Nueva especie de primate con mordida t?xica y dos lenguas

Esta es una de esas historias que bien podr?an parecer una leyenda urbana o completo invento del internet, pero les aseguro que es verdad (no me lo crean a m?, ?verifiquen las referencias!): Investigadores de la universidad de Missouri han descubierto una nueva especie de primate que?a pesar de verse tan tiernos y con cara de ternurita?tienen una mordida letal t?xica y no una sino dos lenguas.

Del grupo de los conocidos como loris perezosos, con un aspecto similar al lemur y que habitan en el sur-sudeste de Asia, se identific? ahora una nueva especie, Nycticebus kayan, habitando una isla en Indonesia.

Una cualidad rara entre los mam?feros y al parecer ?nica en los primates, la mordida de un loris perezoso es t?xica, capaz de causar fiebre, dolor, inflamaci?n e incluso la muerte en humanos que sufren de reacciones al?rgicas. Lo curioso es que las toxinas de su mordida son producidas por gl?ndulas de sus axilas, que lamen con su lengua para combinarlas y activarlas con la saliva de su boca antes de propinar una letal mordida. Las madres pueden tambi?n llegar a untar la toxina en el pelaje de sus cr?as como protecci?n contra los depredadores.

Lo de la segunda lengua es, de hecho, com?n tambi?n en otros prosimios como los l?mures y otros miembros de la familia lorisforme. La formalmente llamada sub-lengua es m?s peque?a, dentada, y se encuentra justo por debajo de su lengua principal. Aunque ?sta no tiene papilas gustativas, al loris perezoso le sirve un como ?cepillo de dientes? para eliminar pelos u otros desechos que se podr?an acumular entre sus dientes.

Incre?ble la cantidad de sorpresas que nos podemos encontrar en el mundo natural, ?no les parece?

Exclusive: Citigroup may exit consumer banking in more countries

NEW YORK (Reuters) - Citigroup Inc is looking to pull out of consumer banking in more countries in an effort to lower costs and boost profits, according to two people familiar with the matter.

In December, Citigroup said it was withdrawing from consumer banking in five countries - Pakistan, Paraguay, Romania, Turkey and Uruguay - as part of an expense reduction plan that will save $1.1 billion a year and eliminate 11,000 jobs. The cuts were one of Michael Corbat's first major steps as chief executive, a position he took in October.

"There is more on the list," said a source familiar with the situation.

The bank has been looking for months at countries, customer segments and products to cut, the source said, but declined to name any of the additional countries.

Sean Kevelighan, a Citigroup spokesman, said the bank is focused on major cities with the highest growth potential for its consumer business and will continue to invest in its franchise and optimize its assets.

Citigroup is one of the most international of U.S. banks, serving consumers in 40 countries out of the 100 in which it has some kind of presence.

Any cuts would likely represent a paring of the portfolio rather than a complete rethinking of the bank's commitment to global consumer banking.

Outside the United States, just three countries - Mexico, South Korea and Australia - account for half of the company's loans to consumers and the bank's presence in many other countries is tiny.

Investors said scaling down in some markets makes sense.

"If they're not going to have a significant presence, they shouldn't be there," said Mark Mandell, portfolio manager at Dalton Investments, which has $1.8 billion under management and owns Citigroup shares.

Selling any of the foreign assets now would be tough. Other lenders around the world have also been closing foreign outposts and buyers can be hard to find. London-based HSBC Holdings Plc, for example, has sold more than 40 businesses and other assets, such as credit card portfolios, globally since 2011, but it has sometimes been a struggle to get the prices it wanted.

Citigroup has some extra complications, too. The bank is using about half its capital to support bad assets and tax benefits related to its huge losses during the financial crisis.

Speaking on a conference call with analysts and investors earlier this month, Corbat said he intends to make regular assessments of "how and where and with whom" the company generates revenue, so the process of cost cutting is more "BAU," or business as usual, instead of a one-time event.

Analysts unsuccessfully pressed Corbat to give more detail about which other countries he might focus on to cut costs.

Corbat, who previously oversaw company operations in Europe, the Middle East and Africa, said that, over time, managers in different countries tend to expand by veering into tangential businesses and end up saddling the company with extraneous and inefficient operations. Other executives at the bank have made similar complaints in the past.

BANAMEX CONUNDRUM

One of the most radical alternatives Citigroup executives have discussed in the past is spinning off its Banamex unit, the second-biggest bank in Mexico, in a public stock offering there. Mexican regulators would likely allow a standalone Banamex to operate with less capital, which would increase its profitability, one of the sources said.

But Banamex is already highly profitable and has a good market position. Selling it would slow Citigroup's efforts to build capital, undercut its strategy of investing in emerging markets and would also mean parting ways with Banamex head Manuel Medina-Mora. Corbat recently named him co-president of Citigroup, which many inside the bank viewed as a sign he is an important part of the new management team.

The global operations long have been both a blessing and a burden for company executives.

Being in many different countries gives the company valuable name recognition and an edge in winning and keeping customers for one of its crown jewels, the Transaction Services unit that moves money internationally for businesses and governments.

But being in so many countries also means its operations are far-flung and subject to myriad local laws and customs. Those problems tend to be greatest in the consumer business. It is harder for the company to capture enough revenue to sufficiently exceed the costs of running branches, a payments network and offering products, such as credit cards.

Two-thirds of the 40 countries where Citigroup does consumer banking provide no more than $2 billion of loans each toward the company's $1.86 trillion in assets. Those small operations include Argentina, Thailand and Russia.

Citigroup's Brazilian unit plans to sell its Credicard consumer finance unit as part of an effort to focus on the most profitable areas, according to a report on Wednesday from newspaper Valor Economico, which did not say how it obtained the information. A Citigroup representative declined to comment.

For the consumer businesses to succeed, Corbat said earlier this month, they have to be capable of being served by common systems for lending, issuing credit cards and opening accounts.

The U.S. consumer bank is also a thorny question for Citigroup. It has much smaller operations in retail banking than many rivals - just about 1,000 branches, less than one-fifth as many as JPMorgan Chase & Co Bank of America Corp and Wells Fargo & Co.

Normally, a bank with a relatively small business might look to sell it, but shedding good assets in the United States is particularly difficult for Citigroup, because the bank needs taxable U.S. revenue to benefit from the nearly $50 billion of deferred tax assets that it has on its books.

Twitter cleans up Vine's hashtags, censors #porn, #sex, other naughty terms

8 hrs.

According to the folks at Twitter, an innocent "human error" was to blame when a pornographic video was featured as an "Editor's Pick" on Vine, but this incident?? combined with a?lack of privacy and abuse prevention controls?? makes it seem as if there's a bit of a porn problem on the new?video-sharing service.

The sudden censorship of certain hashtags further solidifies that belief.

The Verge's Nathan Ingraham was among the first to point out that it appears that the searches for certain naughty hashtags ??such as #porn, #sex, #booty?and similar ??are bringing up no results, even though there are certainly posts with those hashtags.?

I tested this claim by creating a post and tagging it #nsfw. Nothing prevented me from creating this post?? which was entirely innocent, don't worry?? but neither tapping on the hyperlinked hashtag nor searching for #nsfw brought it (or any other posts) into view. Instead, I was shown a frowning emoticon and told that Vine couldn't load any posts. (In the case of searches, the frowning emoticon informed me that no tags matching that term?exist.)?

We have reached out to Twitter to inquire about the missing search results and to see if some sort of cleanup is occurring behind the scenes.?"We're in the process of changing how users find and view sensitive content," a spokesperson explained. "We're experimenting with a number of approaches and will continue to iterate."

Want more tech news?or interesting?links? You'll get plenty of both if you keep up with Rosa Golijan, the writer of this post, by following her on?Twitter, subscribing to her?Facebook?posts,?or circling her?on?Google+.

Immigration reform 101: How would Senate plan actually work?

Features of the bipartisan plan range from more drones along the Rio Grande to a path to citizenship for some 11 million people in the country illegally. But the fight is all about the details.

By Peter Grier,?Staff writer / January 29, 2013

From left to right, Sens. Richard Durbin (D) of Illinois, Charles Schumer (D) of New York, and John McCain (R) of Arizona listen to a question at a news conference on comprehensive immigration reform at the US Capitol in Washington Monday.

On Monday a bipartisan group of eight senators unveiled a proposed overhaul of the US immigration system. The plan includes both increased border enforcement and an eventual path to citizenship for many of the estimated 11 million illegal immigrants already in the country. Yet some important details of the effort remain undefined. According to what we know now, how would the immigration overhaul work?

We?ll give you a stripped-down, ?Immigration 101? version of the plan so you can follow debate on the issue in days and weeks ahead.

First, the senatorial plan calls for devoting increased resources to what it calls ?the basic governmental function of securing our borders." Specifically, it calls for increasing the use of drones and other electronic surveillance equipment, improving radio interoperability, and in general upping the number of agents at and between US border crossings.

?The purpose is to substantially lower the number of successful illegal border crossings while continuing to facilitate commerce," says the proposal.

Second, the plan calls for completion of a system capable of tracking whether people who enter the US via temporary visas have left the country when their visa has expired. Most surveys find that overstays range from 31 to 57 percent of those in the country illegally, according to the Congressional Research Service.

Third, it would establish a commission of Southwestern governors, attorneys general, and community leaders ?to monitor the progress of securing our border and to make a recommendation regarding when the bill?s security measures outlined in the legislation are completed."

The actual importance of this commission is unclear, as we?ll see in a moment.

Fourth, this approach to the problem would require persons who are currently here illegally to register with the government while the security measures are being put in place. Those who pass a background check designed to weed out actual criminals, and who pay a fine and settle all back taxes, would earn a probationary legal status.?

Again, this would occur simultaneously with the all the more-drones-along-the-Rio-Grande stuff. There?s been some confusion about that.

Fifth, citizenship! After the enforcement measures have been completed, those on probationary legal status could stand in the back of the line to get a green card and eventual citizenship. They would not earn these coveted items until everyone who has played by the rules and is already legally waiting has been taken care of.

?Our purpose is to ensure that no one who has violated America?s immigration laws will receive preferential treatment as they relate to those individuals who have complied with the law,? states the proposal.

(Hmm. Haven?t they already received preferential treatment via the probationary legal status thing? What?s the difference between that and a green card? Isn?t legal status, probationary or not, what most illegal immigrants really want? Those are questions the plan?s proponents have yet to address.)

BlackBerry Q10 handson

Forget the all-touch Z10 for a moment. This here is RIM's other BB 10 device -- the BlackBerry Q10. As you can tell from its alphanumeric moniker, that single letter is a nod towards the handset's physical leanings. That's right, it's a hybrid touch / physical QWERTY model and one that diehard BlackBerry fans won't only be more familiar with, but potentially more willing to embrace with open palms. With a 720 x 720 AMOLED display, the Q10's screen is slightly larger than its touch hybrid predecessor, the Bold 9930, and sports a much tighter pixel density.

Sweet 16 Party Ideas : Ideas for Women Home and Family Blog


If you have a daughter then you will be planning a Sweet 16 Birthday party at some point. It is one of the biggest moments in a girls life. There are many parents who go all out for this particular birthday having a prom like party. Depending on your culture this may be the way you go. There are of course some other themes and ideas to choose from.

  1. Tropical/Luau Theme: This is fairly popular where everything looks like Hawaii.
  2. Wonderland Tea Party: I really like this theme because everything looks like the Tea Party Scene from Alice in Wonderland. You can really have a great time with this.
  3. Spa Party: Set up stations where everyone can get mani and pedicures.
  4. Scavenger Hunt: Have everyone drive around looking things. This is a ton of fun and can be done in teams.

These are of course just a few of the million of themes that you can plan. As I said before many go the prom like route with everyone dressing up and the event being formal. The girl turning 16 usually wears a white dress (although this tradition has changed during recent years) and she wears a tiara or crown as well. The ideas is that she is queen of the ball.

Torrey Smith, Ravens WR, Makes It To Super Bowl, Overcoming Adversity On The Way

OWINGS MILLS, Md. -- Torrey Smith overcame a variety of obstacles to become the deep threat the Baltimore Ravens needed to make it to the Super Bowl.

Smith helped his single mother raise her six other children by working after school as a teenager. Early this season, his second with the Ravens, tragedy struck less than 24 hours before Baltimore faced New England on Sept. 23: Smith's younger brother, Tevin Jones, was killed in a motorcycle accident in Virginia.

Smith left the team to join his family, then returned to catch six passes for 127 yards and two touchdowns in Baltimore's 31-30 victory.

Now Smith and the Ravens will play for the NFL championship against San Francisco this Sunday.

Smith has put his brother's death behind him, saying, "I'm just focused on playing football."

Why Small Businesses Throw in the Towel and How to Not Be THAT ...

How are you doing today? ?Feeling good about your business or are you feeling like throwing in the towel?throwing in the towel

Before you throw in the towel, stop and think about why it is that your business isn?t achieving the outcomes that you intended. ?Research shows that the biggest reason that businesses fail is that they simply don?t have enough of the right information to make good decisions. ?Most of the time, that information comes from running surveys. ?And most small business owners think that running surveys is either too hard or too expensive. ?Nothing could be further from the truth ? especially with today?s technology.

Run these surveys first ? before you bail on your business

There are really only two reasons why small businesses don?t generate the income they aspire to:

  1. Not targeting the right customers
  2. Not selling what customers want the way they want it

There is a survey for that.

Let?s start with targeting the right customers. ?You probably have a profile of who YOU think your target customer is. ?Take a moment to define them. ?Start with their demographics:

  • Gender
  • Age
  • Education
  • Location/Geography
  • Income
  • Existing usage or consumption of the product and service that you are selling. ?i.e.?Do you currently own a car

Don?t stop there! ?Demographics are only part of the puzzle. ?Another important element in making sure you?re targeting the right customer is knowing how they think and what matters to them.

Another great question to ask your customers is about what is important to them ? what matters to them when they are buying what you are selling. ?For example, say you are a moving company, you might as a question like this:

When you think about hiring a moving company ? what goes through your mind?

  • Are you going to break my stuff?
  • Are you going to be there on time?
  • How do I know you won?t steal my stuff?

Remember that people purchase products and services based on event triggers. ?An event trigger is something that happens that forces you to go out and purchase. ?So if your computer dies ? that is an event trigger to get you searching for new computers. ?If you discover that you?re having a baby ? that is an event trigger that forces you to start thinking about baby clothes, furniture. etc.

So your next step is to brainstorm all the possible event triggers that should get your ideal customer thinking about you. ?And you can create a survey question about that:

Which of the following have you experienced in the last week?

  • Gained a new customer
  • Lost a big customer
  • Added a new sales rep
  • Launched a new product

Make sure you?re selling what they want to buy

Most marketing texts and experts will tell you that you have to STAND out and be unique. ?And you probably think that means selling something that no one else is selling. ?This is COMPLETELY WRONG. ?Your goal is to sell something that people are buying FIRST ? then look for unique ways to distinguish your product from the many others that are being sold.

Here?s an example ? I love shoes ? in fact, I probably have something like five different kinds of boots. ?I have flat boots and high heeled boots, suede boots and leather boots, brown boots, black boots, casual boots and dressy boots ? do I need to go on? ?The product us BOOTS ? and I like buying boots and I will keep buying boots so long as they are different from the ones that I already have. ?So the next person that offers a blue suede boot ? is likely to sell it to me.

Your product or service is the boot. ?Your competition is selling black boots ? what kind of boots will YOU sell?

And this is where an online survey can come in really handy -

Do you buy boots?

How likely are you to buy boots with your favorite NFL team?s logo on them?

See how that works?

Don?t guess or wonder ? just ask

If you?ve been holding back from interacting with your customers and doing surveys ? this could be killing your business. ?Instead of wondering and guessing ? just ask your prospects and customers what they think.

Start with some general conversations. ?Then take what you?ve learned and put it into a survey that asks some very specific questions. ?Share the survey via your social media channels and with your customers. ?Be sure to offer an incentive or a reward of some kind to entice them to participate. ?See what they say and take their opinions into consideration when you take your next step.

Bonus survey hint

Before you put your survey questions together ? be sure to write down all the decisions you?re trying to make ?

  • Should I make red boots or blue boots
  • Should I deliver in 30 minutes or less
  • I need to sell at least 100 units per month to be successful

Then structure your survey so that the responses are answers to these questions and so that you can make that decision. ?Here?s what I mean. ?Say you need to sell 100 units per month of a specific product or service ? you might ask

  • Do you purchase these widgets monthly?
  • If yes ? how many widgets do you purchase each month?
  • This is a widget that sings and dances the cha cha ? would you buy this widget if it were available?
  • How many cha cha dancing widgets would you buy each month?
  • How much are you willing to pay for a cha cha dancing widget?

Doing this kind of survey with your customers can mean the difference between success and failure. ?Don?t fail until you?ve tried this.

Survival of the prettiest: Sexual selection can be inferred from the fossil record

Survival of the prettiest: Sexual selection can be inferred from the fossil record [ Back to EurekAlert! ] Public release date: 29-Jan-2013

University of Southampton

Detecting sexual selection in the fossil record is not impossible, according to scientists writing in Trends in Ecology and Evolution this month, co-authored by Dr Darren Naish of the University of Southampton.

The term "sexual selection" refers to the evolutionary pressures that relate to a species' ability to repel rivals, meet mates and pass on genes. We can observe these processes happening in living animals but how do palaeontologists know that sexual selection operated in fossil ones?

Historically, palaeontologists have thought it challenging, even impossible, to recognise sexual selection in extinct animals. Many fossil animals have elaborate crests, horns, frills and other structures that look like they were used in sexual display but it can be difficult to distinguish these structures from those that might play a role in feeding behaviour, escaping predators, controlling body temperature and so on.

However in their review, the scientists argue that clues in the fossil record can indeed be used to infer sexual selection.

"We see much evidence from the fossil record suggesting that sexual selection played a major role in the evolution of many extinct groups," says Dr Naish, of the University's Vertebrate Palaeontology Research Group.

"Using observations of modern animal behaviour we can draw analogies with extinct animals and infer how certain features improve success during courtship and breeding."

Modern examples of sexual selection, where species have evolved certain behaviours or ornamentation that repel rivals and attract members of the opposite sex, include the male peacock's display of feathers, and the male moose's antlers for use in clashes during mating season.

Dr Naish and co-authors state that the fossil record holds many clues that point to the existence of sexual selection in extinct species, for example weaponry for fighting, bone fractures from duels, and ornamentation for display, such as fan-shaped crests on dinosaurs. Distinct differences between males and females of a species, called 'sexual dimorphism', can also suggest the presence of sexual selection, and features observed in sexually mature adults, where absent from the young, indicate that their purpose might be linked to reproduction.

We can also make inferences from features that are 'costly' in terms of how much energy they take to maintain, if we assume that the reproductive advantages outweighed the costs.

Whilst these features might have had multiple uses, the authors conclude that sexual selection should not be ruled out.

"Some scientists argue that many of the elaborate features on dinosaurs were not sexually selected at all," adds Dr Naish, who is based at the National Oceanography Centre, Southampton.

"But as observations show that sexual selection is the most common process shaping evolutionary traits in modern animals, there is every reason to assume that things were exactly the same in the distant geological past."

New look at cell membrane reveals surprising organization

Jan. 28, 2013 ? Sight would dramatically alter a blind man's understanding of an elephant, according to the old story. Now, a look directly at a cell surface is changing our understanding of cell membrane organization.?

Using a completely new approach to imaging cell membranes, a study by researchers from the University of Illinois, Lawrence Livermore National Laboratory and the National Institutes of Health revealed some surprising relationships among molecules within cell membranes.

Led by Mary Kraft, a U. of I. professor of chemical and biomolecular engineering, the team published its findings in the Proceedings of the National Academy of Sciences.

Cells are enveloped in semi-permeable membranes that act as a barrier between the inside and outside of the cell. The membrane is mainly composed of a class of molecules called lipids, studded with proteins that help regulate how the cell responds to its environment.

"Lipids have multiple functions serving as both membrane structure and signaling molecules, so they regulate other functions inside the cell," Kraft said. "Therefore, understanding how they're organized is important. You need to know where they are to figure out how they're doing these regulatory functions."

One widely held belief among cell biologists is that lipids in the membrane assemble into patches, called domains, that differ in composition. However, research into how lipids are organized in the membrane, and how that organization affects cell function, has been hampered by the lack of direct observation. Although the cell membrane is heavily studied, the imaging techniques used infer the locations of certain molecules based on assumed associations with other molecules.

In the new study, Kraft's team used an advanced, molecule-specific imaging method that allowed the researchers to look at the membrane itself and map a particular type of lipid on mouse cell membranes. The researchers fed lipids labeled with rare stable isotopes to the cells and then imaged the distribution of the isotopes with high-resolution imaging mass spectrometry.

Called sphingolipids (SFING-go-lih-pids), these molecules are thought to associate with cholesterol to form small domains about 200 nanometers across. The direct imaging method revealed that sphingolipids do indeed form domains, but not in the way the researchers expected.

The domains were much bigger than suggested by prior experiments. The 200-nanometer domains clustered together to form much larger, micrometer-sized patches of sphingolipids in the membrane.

"We were amazed when we saw the first images of the patches of sphingolipids across the cell surface," said Peter Weber, who directed the team at Lawrence Livermore National Laboratory. "We weren't sure if our imaging mass spectrometry method would be sensitive enough to detect the labeled lipids, let alone what we would see."

Furthermore, when the researchers looked at cells that were low on cholesterol -- thought to play a key role in lipid aggregation -- they were surprised to find that the lipids still formed domains. On the other hand, disruption to the cell's structural scaffold seemed to dissolve the lipid clusters.

"We found that the presence of domains was somewhat affected by cholesterol but was more affected by the cytoskeleton -- the protein network underneath the membrane," Kraft said. "The central issue is that the data are suggesting that the mechanism that's responsible for these domains is much more complicated than initially expected."

In addition, the new study found that sphingolipids domains were incompletely associated with a marker protein that researchers have long assumed dwelled where sphingolipids congregated. This means that data collected with imaging techniques that target this protein are not as accurate in representing sphingolipid distribution as previously thought.

"Our data are showing that if you want to know where sphingolipids are, look at the lipid, don't infer where it is based on other molecules, and now there's a way to directly image them," said Kraft, who also is affiliated with the department of chemistry at the U. of I.

Next, the researchers plan to use the direct-imaging method in conjunction with other more conventional methods, such as fluorescence, to further determine the organization of different kinds of molecules in the membrane, their interactions and how they affect the cell's function. They plan to begin by targeting cholesterol.

"Cholesterol abundance is important," Kraft said. "You change that, you tremendously change cell function. How is it organized? Is it also in domains? That's related to the question, what's the mechanism responsible for these structures and what are they doing?"

Preliminary FEMA flood zone maps add 35,000 NYC buildings to ...

Michael Heiman / Getty Images file

The corner of 34th Street and 1st Street in Manhattan floods during rains from Hurricane Sandy, Oct. 29, 2012 in New York City.

By Miranda Leitsinger, Staff Writer, NBC News

Some 35,000 buildings and homes have been added to flood zones in parts of New York City, according to preliminary maps released Monday by the Federal Emergency Management Agency. More of these maps will be released in late February for Manhattan and other parts of city where the data is still being analyzed.?

The numbers emerged after the release earlier in the day of FEMA?s advisory flood maps for parts of the city, increasing the areas falling into 100-year flood zones or areas with the potential for destructive high speed waves along coastlines, said agency spokesman Dan Watson. More maps will be released for other parts of the city, including Manhattan, in late February, he said.?



The official maps will be released in the summer, but the preliminary ones for hard-hit areas like Staten Island and Queens are intended to give those who are rebuilding a head start. Sandy struck Oct. 29, leaving about 20,000 residential buildings in the city with some damage or disruption to their utilities.

?It can inform building back stronger and smarter with the recovery,? Watson said. ?And honestly it will also help save lives and property in the future ? because we?ve seen areas where folks have elevated or used other forms of mitigation and ? they got wet but there wasn?t as much damage as a result of it.??

The maps reflect base flood elevations and will likely increase insurance rates for those who are newly included in the flood-prone zones. Those who are now in the ?A Zones? -- or 100-year flood zones, where a flooding event has a one percent probability of occurring in any given year -- and who have a federally-backed mortgage will now be required to get flood insurance, Watson said.

Some property owners may also have to elevate their buildings or homes, likely setting ground floors ground floors 3 to 6 feet higher than zoning rules previously required, according to The Associated Press. The maps have to be adopted by communities, which can appeal parts of them, Watson said.

Congress has already passed $9.7 billion in additional borrowing authority for the National Flood Insurance Program to help pay Sandy claims from homeowners in New York and New Jersey.?The Senate on Monday night approved a $50.5 billion emergency spending bill to aid people in New York and New Jersey who are trying to rebuild their homes and businesses.

Hard-hit communities were just beginning to figure out what these initial maps mean for them. In Breezy Point, a private cooperative in the city?s southern Queens Borough heavily damaged by the storm, leaders said they needed to study the maps before offering guidance: ?Keep in mind that the DOB (Department of Buildings) and City still need to make decisions regarding building criteria and if it will change.?

Obama and police chiefs discuss assault rifles, background checks (+video)

During President Obama's meeting with police chiefs and sheriffs today, the law enforcement officials focused on the need for background checks and closing the gaping reporting holes.

By Nedra Pickler,?Associated Press / January 28, 2013

(L-R) Minneapolis Police Chief Janee Harteau, Hennepin County Minnesota Sheriff Richard W. Stanek, and President Barack Obama met today with other representatives from the Major Cities Chiefs Association and Major County Sheriffs Association to discuss President Obama's policies to reduce gun violence.

Law enforcement leaders who met with President Barack Obama Monday urged him to focus on strengthening gun purchase background checks and mental health systems, but did not unify behind his more controversial gun control efforts.

The message from sheriffs and police chiefs gathered at the White House reflected the political reality in Congress that the assault weapons ban in particular is likely to have a hard time winning broad support. The president appeared to recognize the challenge of getting everything he wants from Congress as well, participants in the meeting said.

"We're very supportive of the assault weapons ban," as police chiefs, said Montgomery County, Md., Police Chief J. Thomas Manger in an interview with The Associated Press. "But I think everybody understands that may be a real tough battle to win. And one of the things that the president did say is that we can't look at it like we have to get all of these things or we haven't won."

Opinions over an assault weapons ban and limits on high capacity magazines ? two measures the president supports ? were divided in the room. While Manger said the police chiefs from the large cities support that kind of gun control, some of the elected sheriffs who were in the meeting may not.

"I think what was made clear was that gun control in itself is not the salvation to this issue," said Sheriff Paul Fitzgerald of Story County, Iowa, one of 13 law enforcement leaders who met with the president, vice president and Cabinet members for more than an hour, seated around a conference table in the Roosevelt Room.

Among the participants included three chiefs that responded to the worst shootings of 2012, including Aurora, Colo., where 12 were killed in July; Oak Creek, Wis., where six died in an assault on a Sikh temple, and Newtown, Conn., scene of the most recent mass tragedy that left 20 first-graders dead.

The White House recognizes that police are a credible and important voice in the debate over guns that has developed following last month's elementary school shooting in Connecticut. Obama opened the meeting before media cameras and declared no group more important to listen to in the debate.

"Hopefully if law enforcement officials who are dealing with this stuff every single day can come to some basic consensus in terms of steps that we need to take, Congress is going to be paying attention to them, and we'll be able to make progress," Obama said.

Obama urged Congress to pass an assault weapons ban, limit high capacity magazines and require universal background checks for would-be gun owners in a brief statement to the reporters. But participants said after the media was escorted from the room, the focus was not on the assault weapons ban.

(AP) ? Yahoo got a little healthier during the last three months of 2012 as the long-suffering Internet company took advantage of higher ad prices and more money coming in from overseas investments to deliver numbers that exceeded analyst forecasts.

The results announced Monday covered Yahoo's first full quarter under CEO Marissa Mayer. Yahoo Inc. lured Mayer away from Google Inc. in mid-July in its latest attempt to snap out of a funk that had depressed its revenue and stock price.

Although Yahoo still isn't keeping pace with the overall growth of the Internet ad market, the company fared well enough during the fourth quarter to produce its first full-year gain in revenue since 2008. It was a scant increase: just $2.4 million higher than 2011's total of nearly $5 billion.

Yahoo is now being run by its fifth permanent or interim CEO since 2008.

Mayer, 37, has raised hopes among investors and employees with her Google pedigree and her pledge to transform Yahoo's website into a mesmerizing destination that attracts Web surfers and advertisers. During her first six months on the job, she has primarily focused on boosting employee morale and building better mobile and social-networking services so Yahoo can make more money from two of technology's hottest trends.

"The future of Yahoo will be about innovation, execution and continued progress on a multi-year march toward growth, delighting users and driving shareholder value," Mayer assured analysts in a Monday conference call.

Investors seem convinced Mayer is headed in the right direction. Yahoo's stock added 50 cents, or nearly 2.5 percent, to $20.81 in extended trading. The shares are up by more than 30 percent since Mayer joined the Sunnyvale, Calif., company.

Yahoo has been feeding the rally by using part of a $7.6 billion windfall that it received from selling half its stake in Chinese Internet company Alibaba Group. The company spent $1.5 billion buying back nearly 80 million of its shares at an average price of $18.24 in the fourth quarter. Buybacks help boost the stock price for remaining shareholders.

Mayer highlighted some of the company's recent strides during the conference call. She said internal surveys show 95 percent of Yahoo's 11,500 employees are optimistic about the company's future. Mayer also touted the potential of a recent redesign of Yahoo's email, saying the number of daily users has increased by 10 percent since the changes were unveiled last month.

Yet Mayer's efforts haven't made a huge difference in Yahoo's ad sales ? the company's main way of making money.

For instance, during the final three months of last year, Yahoo's ad revenue was $1.07 billion, roughly the same as a year earlier. By contrast, fourth-quarter ad revenue at Google surged by 19 percent from the previous year. Another rival, Facebook Inc., is expected to post much stronger ad growth Wednesday when the Internet social-networking leader is scheduled to release its fourth-quarter report.

Overall, Yahoo's fourth-quarter earnings dipped 8 percent to $272 million, or 23 cents per share, down from $296 million, or 24 cents per share. The earnings would have been higher than the previous year, if not for a charge to close its South Korea operations and other one-time accounting items.

If not for those charges, Yahoo said it would have earned 32 cents per share. On that basis, Yahoo topped the average estimate of 27 cents per share among analysts surveyed by FactSet.

Yahoo's fourth-quarter revenue increased 2 percent from the previous year to $1.35 billion.

After subtracting advertising commissions, Yahoo's fourth-quarter revenue stood at $1.22 billion ? about $10 million above analyst forecasts.

Yahoo apparently isn't expecting a big upturn this year. The company predicted its revenue, minus commissions, will range from $1.07 billion to $1.1 billion in the current quarter. That's slightly below analysts' average estimate of $1.12 billion.

In an encouraging sign, Yahoo's average price for display advertising on its website during the fourth quarter rose 7 percent from the previous year. Meanwhile, the average price for Yahoo's search ads increased by 1 percent from the previous year. This marked the first time that Yahoo has detailed the changes in its ad rates from the previous year. The fourth-quarter improvement could be an indication that advertisers believe Mayer's changes are starting to pay off.

Yahoo still needs to work on increasing the volume of display advertising, which declined by 10 percent from the previous year. The number of revenue-generating search ads, though, increased 11 percent from the previous year. That improvement provided proof that Yahoo is harvesting better returns from its Internet-search partnership with Microsoft Corp. The alliance has allowed Yahoo to lower its expenses by relying on Microsoft's technology for most of its search results, but the arrangement had been producing disappointing returns on the advertising front until recently.

Yahoo is still benefiting from its remaining holdings in Alibaba, as well as a roughly 35 percent in Yahoo Japan. Yahoo's fourth-quarter income from its investments increased 17 percent from the previous year to nearly $149 million. Because of a lag in how Yahoo books income from international revenue, the company's results still don't fully reflect the reduced stake in Alibaba. That will occur this year, reducing Yahoo's overseas earnings.

Iran sends monkey into space, showing missile progress

DUBAI (Reuters) - Iran said on Monday it had launched a live monkey into space, seeking to show off missile delivery systems that are alarming the West which fears the technology could be used to deliver a nuclear warhead.

The Defense Ministry announced the launch as world powers sought to agree a date and venue with Iran for resuming talks to resolve a standoff with the West over Tehran's nuclear program before it degenerates into a new Middle East war.

Efforts to nail down a new meeting have failed repeatedly and the powers fear Iran is exploiting the diplomatic vacuum to hone the means to produce nuclear weapons.

The Islamic Republic denies seeking weapons capability and says it seeks only electricity from its uranium enrichment so it can export more of its considerable oil wealth.

The powers have proposed new talks in February, a spokesman for the European Union's foreign policy chief said on Monday, hours after Russia urged all concerned to "stop behaving like children" and commit to a meeting.

Iran earlier in the day denied media reports of a major explosion at one of its most sensitive, underground enrichment plants, describing them as Western propaganda designed to influence the nuclear talks.

The Defense Ministry said the space launch of the monkey coincided "with the days of" the Prophet Mohammad's birthday, which was last week, but gave no date, according to a statement carried by the official news agency IRNA.

The launch was "another giant step" in space technology and biological research "which is the monopoly of a few countries", the statement said.

The small grey monkey was pictured strapped into a padded seat and being loaded into the Kavoshgar rocket dubbed "Pishgam" (Pioneer) which on state media said reached a height of more than 120 km (75 miles), IRNA said.

"This shipment returned safely to Earth with the anticipated speed along with the live organism," Defense Minister Ahmad Vahidi told the semi-official Fars news agency. "The launch of Kavoshgar and its retrieval is the first step towards sending humans into space in the next phase."

There was no independent confirmation of the launch.

SIGNIFICANT

The West worries that long-range ballistic technology used to propel Iranian satellites into orbit could be put to use delivering nuclear warheads.

Bruno Gruselle of France's Foundation for Strategic Research said that if the monkey launch report were true it would suggest a "quite significant" engineering feat by Iran.

"If you can show that you are able to protect a vehicle of this sort from re-entry, then you can probably protect a military warhead and make it survive the high temperatures and high pressures of re-entering," Gruselle said.

The monkey launch would be similar to sending up a satellite weighing some 2,000 kg (4,400 pounds), he said. Success would suggest a capacity to deploy a surface-to-surface missile with a range of a few thousand kilometers (miles).

But Michael Elleman, a missile expert at the International Institute for Strategic Studies think-tank, said Iran had demonstrated "no new military or strategic capability" with the launch.

"Nonetheless, Iran has an ambitious space exploration program that includes the goal of placing a human in space in the next five or so years and a human-inhabited orbital capsule by the end of the decade," Elleman said. "Today's achievement is one step toward the goal, albeit a small one."

The Islamic Republic announced plans in 2011 to send a monkey into space, but that attempt was reported to have failed.

Nuclear-weapons capability requires three components - enough fissile material such as highly enriched uranium, a reliable weapons device miniaturized to fit into a missile cone, and an effective delivery system, such as a ballistic missile that can grow out of a space launch program.

Iran's efforts to develop and test ballistic missiles and build a space launch capability have contributed to Israeli calls for pre-emptive strikes on Iranian nuclear sites and billions of dollars of U.S. ballistic missile defense spending.

MANOEUVRING OVER NEXT TALKS

A spokesman for EU foreign policy chief Catherine Ashton said the powers had offered a February meeting to Iran, after a proposal to meet at the end of January was refused.

"Iran did not accept our offer to go to Istanbul on January 28 and 29 and so we have offered new dates in February. We have continued to offer dates since December. We are disappointed the Iranians have not yet agreed," Michael Mann reporters.

He said Iranian negotiators had imposed new conditions for resuming talks and that EU powers were concerned this might be a stalling tactic. The last in a sporadic series of fruitless talks was held last June.

Iranian officials deny blame for the delays and say Western countries squandered opportunities for meetings by waiting until after the U.S. presidential election in November.

"We have always said that we are ready to negotiate until a result is reached and we have never broken off discussions," IRNA quoted Iranian Foreign Minister Ali Akbar Salehi as saying.

Salehi has suggested holding the next round in Cairo but said the powers wanted another venue. He also said that Sweden, Kazakhstan and Switzerland had offered to host the talks.

In Moscow, Russian Foreign Minister Sergei Lavrov told a news conference: "We are ready to meet at any location as soon as possible. We believe the essence of our talks is far more important (than the site), and we hope that common sense will prevail and we will stop behaving like little children."

Ashton is overseeing diplomatic contacts on behalf of the powers hoping to persuade Tehran to stop higher-grade uranium enrichment and accept stricter U.N. inspections in return for civilian nuclear cooperation and relief from U.N. sanctions.

IRAN DENIES FORDOW BLAST

Reuters has been unable to verify reports since Friday of an explosion early last week at the underground Fordow bunker that some Israeli and Western media said wrought heavy damage.

"The false news of an explosion at Fordow is Western propaganda ahead of nuclear negotiations to influence their process and outcome," IRNA quoted deputy Iranian nuclear energy agency chief Saeed Shamseddin Bar Broudi as saying.

In late 2011 the plant at Fordow began producing uranium enriched to 20 percent fissile purity, well above the 3.5 percent level normally needed for nuclear power stations.

Western governments say the higher-grade enrichment marks a notable step towards weapons-grade uranium, even though it is below the 90 percent level suitable for nuclear bombs.

Iran says its enhanced enrichment is to make fuel for a Tehran research reactor that produces isotopes for medical care.

Diplomats in Vienna, where the U.N. nuclear watchdog agency is based, said on Monday they had no knowledge of any incident at Fordow but were looking into the reports. One Western diplomat said he did not believe them to be correct.

The U.N. International Atomic Energy Agency, which regularly inspects Iranian nuclear sites including Fordow, had no immediate comment.

Iran has accused Israel and the United States of trying to sabotage its nuclear program with cyber attacks and assassinations of its nuclear scientists. Washington has denied any role in the killings while Israel has declined to comment.

No, President Obama Does Not Want to Talk about 2016

On Sunday night, 60 Minutes'?Steve Kroft sat down with President Obama and outgoing Secretary of State Hillary Clinton, neither of whom seem very interested in talking about the next election. It was a feel-good 30-minutes of chatting if anything and a rare sight to see the two politicians in a joint interview. Niceties were exchanged, heads nodded, hands crossed. Barack wore blue. Hillary wore pink. And neither of them dared say a word about the next election.

RELATED: Obama Foreign Policy: 'Leading from Behind'

That doesn't mean Kroft didn't ask. Pivoting gracefully on the president's praise for Hillary, Kroft asked, "What's the expiration on this endorsement." You can almost ?hear the sound of Obama's internet eye-rolling. "You know, Steve, I gotta tell you, the -- you guys in the press are incorrigible," said the president, whose vice president is eyeing the nomination. "I was literally inaugurated four days ago. And you're talking about elections four years from now."

RELATED: Hillary Clinton Falls on Her Sword

So Kroft turns to Clinton. "Yeah, and I am, as you know, Steve, I am still secretary of state," said Clinton. "So I'm out of politics. And I'm forbidden from even hearing these questions." She could've just said, "Yeah, and I am, as you know, Steve, I am not running for office in 2016. I've said that several times now, okay?" Or, of course, she could've announced her candidacy! (Highly unlikely.) That would've been bad timing, though, because what followed were a bunch of somewhat serious questions about her Benghazi testimony -- She "deeply regrets what happened" -- and her health -- "It's great."

RELATED: Can Conservative Media Stomach Another Week of Weinergate?

The rest of the chat goes about as you might expect. Obama talked about how much he admired Hillary during the primary campaign, and Hillary guffawed about how she tried to turn down the president's job offer. Obama talked about how the world is "big and chaotic" and "dangerous." Clinton reminded everyone, "We're on the side of freedom." It was all very patriotic and appropriate and expected. It's nice to see a couple of powerful political leaders pat each other on the back sometimes, but do go over thinking anything they say. When Kroft asked at the beginning of the interview if there were any political tea leaves to be read into what they were saying, Hillary chimed right in, "We don't have any tea. We've got some water here is the best I can tell."

Senate Immigration Proposal to Include Pathway to Citizenship

Two senators at the center of negotiations over comprehensive immigration reform, Sen. John McCain (R-Ariz.) and Sen. Bob Menendez (D-N.J.) said on Sunday that a pathway to citizenship is an essential component of a comprehensive reform bill.

"That has to be also part of it," McCain told ABC News' Martha Raddatz on "This Week" when asked whether a pathway to citizenship would be a component of reform. "There's a new appreciation on both sides of the aisle including, maybe more importantly on the Republican side of the aisle, that we have to enact comprehensive immigration reform."

Like "This Week" on Facebook here. You can also follow the show on Twitter here.

McCain said that a small group of Senators will release the principles of a comprehensive, not "piecemeal," reform bill this week.

"I'm very pleased with the progress," McCain said. "It's not that much different from what we tried to do in 2007."

Read a full transcript of the interview with Sens. McCain and Menendez HERE.

Menendez, who met with President Obama on Friday along with other members of the Congressional Hispanic Caucus leadership, said that the president expressed his full commitment to reform.

"The president made it very clear in that discussion that this was a top legislative priority for him in this session of the Congress and that he expects to work with all of us in an effort to achieve that goal and he's fully committed to it."

He added that a pathway to "earned legalization" is an "essential element" of an immigration reform bill.

"First, Americans support it in poll after poll. Secondly, Latino voters expect it. Thirdly Democrats want it. And fourth Republicans need it," Menendez said.

McCain added that he believes Obama's use of the presidential podium on behalf of immigration reform at an event in Las Vegas planned for Tuesday will aid efforts to pass a bill.

"I think it helps," McCain said. "I think its important that we all work together on this."

"Believe it or not, I see a glimmer of bipartisanship out there," he added.

26/444 Healing from Infidelity: Play and the Message of the Affair

Chili hasn't been with us for a couple years now but I still love this pic. Chili

Most relationships begin with a lot of play. Couples truly enjoy one another in an atmosphere of fun. Ann and I had lost that. In trying to be a good Christian man I decided that our spare time would be family time. This sounded good to me. The decision left a deep part of my wife neglected. We didn't have fun time together alone.

Our relationship had become dull. We were busy doing lots of good, kind meaningful activities. We had fun with others and fun with our kids. Together we paid bills, taught Sunday school, fed the dog, watched TV etc. Part of Ann's affair and most affairs is recapturing fun, a sense of life, even if it is outside what one knows to be true and right. The intoxication of feeling alive again overshadows all else. Ann desired for that feeling of life again in our marriage.

Her desire was good. The direction she chose to pursue it wasn't. ?

Before we figured out how to bring that back into our relationship, or maybe even know that we needed to, another man showed up with time to give and enjoyed fun times with Ann. Making it through an affair involves understanding the message it was sending about the marriage. I resisted wanting to use 'the messages of the affair' for a while. I had a choice of whether to learn from the most painful experience of my life or to stay resentful.

It wasn't a linear process but eventually I chose to learn. Ann and I recaptured a sense of play in the midst of doing all the day to day of life. We like to be goofy together. We tickle. We joke. We laugh at ourselves. We flirt. I like flirting with her. And we like to be silly with our dog Chili by putting brightly colored ribbons on his head.

[Phoronix] Ubuntu 13.04 Will Improve Gaming On Open-Source ...

While still a ways from being comparable to the proprietary graphics drivers in terms of features and OpenGL performance, the open-source GPU drivers found by default in the forthcoming Ubuntu 13.04 release are a big improvement over the out-of-the-box graphics drivers found in earlier Ubuntu Linux releases. The Ubuntu desktop is also faster thanks to improvements to its Unity desktop environment and Compiz compositing window manager. In this article are Linux gaming benchmarks looking at the performance of Fedora 17, Fedora 18, Ubuntu 12.10, and a preliminary Ubuntu 13.04 development snapshot. In this first article, the OpenGL performance of Intel and Radeon graphics are being benchmarked.

The Radeon and Intel graphics benchmarking of the recent Fedora and Ubuntu releases were done on two distinctly different systems. First up are benchmarks of the Radeon graphics stack from Fedora 17, Fedora 18, Ubuntu 12.10, and an Ubuntu 12.03 snapshot from the 21st of January. The graphics card used for all of this testing was an ATI Radeon HD 4650 graphics card from the Intel Core i7 3960X Extreme Edition test-bed.

The Fedora and Ubuntu installations were all done in their stock configurations (aside from disabling swap buffers wait for the xf86-video-ati DDX). The key information on each OS for these gaming tests comes down to Fedora 17 being powered by the Linux 3.3 kernel with Mesa 8.0.2, Fedora 18 with Linux 3.6 and Mesa 9.0.1, Ubuntu 12.10 with the Linux 3.5 kernel and Mesa 9.0, and Ubuntu 13.04 with a development snapshot of the Linux 3.8 Git kernel and Mesa 9.0.1. Prior to the Ubuntu 13.04 release in April will also be the pulling in of Mesa 9.1.

Fedora continues to ship the GNOME Shell as its default desktop while Ubuntu is obviously with Unity over Compiz. Beyond the continued improvements to the open-source graphics stack, Ubuntu 13.04 also has significant optimization work going on for Unity/Compiz to make it a better platform for Linux gaming.
