Mar. 26, 2013 ? Africa isn't the kind of place you might expect to find penguins. But one species lives along Africa's southern coast today, and newly found fossils confirm that as many as four penguin species coexisted on the continent in the past. Exactly why African penguin diversity plummeted to the one species that lives there today is still a mystery, but changing sea levels may be to blame, the researchers say.
The fossil findings, described in the March 26 issue of the Zoological Journal of the Linnean Society, represent the oldest evidence of these iconic tuxedo-clad seabirds in Africa, predating previously described fossils by 5 to 7 million years.
Co-authors Daniel Thomas of the National Museum of Natural History and Dan Ksepka of the National Evolutionary Synthesis Center happened upon the 10-12 million year old specimens in late 2010, while sifting through rock and sediment excavated from an industrial steel plant near Cape Town, South Africa.
Jumbled together with shark teeth and other fossils were 17 bone fragments that the researchers recognized as pieces of backbones, breastbones, wings and legs from several extinct species of penguins.
Based on their bones, these species spanned nearly the full size spectrum for penguins living today, ranging from a runty pint-sized penguin that stood just about a foot tall (0.3 m), to a towering species closer to three feet (0.9 m).
Only one penguin species lives in Africa today -- the black-footed penguin, or Spheniscus demersus, also known as the jackass penguin for its loud donkey-like braying call. Exactly when penguin diversity in Africa started to plummet, and why, is still unclear.
Gaps in the fossil record make it difficult to determine whether the extinctions were sudden or gradual. "[Because we have fossils from only two time periods,] it's like seeing two frames of a movie," said co-author Daniel Ksepka. "We have a frame at five million years ago, and a frame at 10-12 million years ago, but there's missing footage in between."
Humans probably aren't to blame, the researchers say, because by the time early modern humans arrived in South Africa, all but one of the continent's penguins had already died out.
A more likely possibility is that rising and falling sea levels did them in by wiping out safe nesting sites.
Although penguins spend most of their lives swimming in the ocean, they rely on offshore islands near the coast to build their nests and raise their young. Land surface reconstructions suggest that five million years ago -- when at least four penguin species still called Africa home -- sea level on the South African coast was as much as 90 meters higher than it is today, swamping low-lying areas and turning the region into a network of islands. More islands meant more beaches where penguins could breed while staying safe from mainland predators.
But sea levels in the region are lower today. Once-isolated islands have been reconnected to the continent by newly exposed land bridges, which may have wiped out beach nesting sites and provided access to predators.
Although humans didn't do previous penguins in Africa in, we'll play a key role in shaping the fate of the one species that remains, the researchers add.
Numbers of black-footed penguins have declined by 80% in the last 50 years, and in 2010 the species was classified as endangered. The drop is largely due to oil spills and overfishing of sardines and anchovies -- the black-footed penguin's favorite food.
"There's only one species left today, and it's up to us to keep it safe," Thomas said.

LOS ANGELES (AP) ? David Petraeus apologized Tuesday night to an audience of veterans for the conduct that led to his resignation as head of the CIA following the disclosure of an extramarital affair.
"Needless to say, I join you keenly aware that I am regarded in a different light now than I was a year ago," Petraeus said. "I am also keenly aware that the reason for my recent journey was my own doing. So please allow me to begin my remarks this evening by reiterating how deeply I regret ? and apologize for ? the circumstances that led to my resignation from the CIA and caused such pain for my family, friends and supporters."
Dressed in a civilian's dark suit and red tie, Petraeus gave his first public speech since his resignation to about 600 people, including many uniformed and decorated veterans at the University of Southern California's annual ROTC dinner. The hero of the Iraq and Afghanistan wars has remained largely in seclusion since resigning. His lawyer, Robert B. Barnett, has said that Petraeus has spent much of that time with his family.
While the speech was peppered with jokes about USC and UCLA's longstanding rivalry, he mostly talked about getting better treatment for veterans and soldiers, but stopped short of criticizing current practices.
"While our country continues to improve its support and recognition for all of our veterans and their families, we can and must do more," he said.
Petraeus received applause and a standing ovation before he began the evening's program by cutting a cake with a sword in military tradition, a task reserved for the highest ranking person in the room.
The retired four-star general's affair with his biographer, Paula Broadwell, was discovered during an FBI investigation into emails she sent to another woman she viewed as a rival for his attention.
"I know I can never fully assuage the pain that I inflicted on those closest to me and a number of others," said Petraeus, in a somber tone to the audience that included his wife. He also mentioned their children.
At the time the affair was made public, Petraeus told his staff he was guilty of "extremely poor judgment."
"Such behavior is unacceptable, both as a husband and as the leader of an organization such as ours," he said.
On Tuesday night, Petraeus noted the challenges of transitioning from military life to civilian life, a path he is currently navigating.
"There's often a view that because an individual was a great soldier, he or she will naturally do well in civilian world," Petraeus said. "In reality, the transition from military service to civilian pursuits is often quite challenging."
As the military leader credited with reshaping the nation's counterinsurgency strategy, turning the tide in the U.S. favor in both Iraq and Afghanistan and making the U.S. safer from terrorism, Petraeus had a friendly audience at the ROTC dinner.
At least one expert in crisis communications said that if his apology comes across as heartfelt and sincere, the public will indeed be seeing much more of him.
"America is a very forgiving nation," said Michael Levine who, among dozens of other celebrity clients, represented Michael Jackson during his first child molestation investigation.
"If he follows the path of humility, personal responsibility and contrition, I submit to you that he will be very successful in his ability to rehabilitate his image," he said.
Another longtime crisis communications expert, Howard Bragman, said Petraeus has handled the situation perfectly so far and he expects he'll continue to do so. He noted that unlike former President Bill Clinton, former U.S. Sen. John Edwards and other public figures caught in extramarital affairs, Petraeus didn't try to lie his way out of it, immediately took responsibility and moved on.
"I think the world is open to him now," said Bragman, vice chairman of the image-building company Reputation.com. "I think he can do whatever he wants. Realistically, he can even run for public office, although I don't think he'd want to because he can make more money privately."
Ahead of the speech, Petraeus drew lavish praise from USC's president, C. L. Max Nikias, who called him "arguably the most effective military commander since Gen. Dwight D. Eisenhower."
"In our post 9/11 world, Gen. Petraeus' influence on our military is unmatched, and his contributions to the CIA are far-reaching," Nikias said.
While at USC, Petraeus also planned to visit faculty and students at the Price School of Public Policy, which administers the ROTC program, and USC's School of Social Work, which trains social workers in how to best help veterans returning from war.
Petraeus was presented with a gift of silver cuff links by Nikias after his speech.

Just ahead of T-Mobile's event in New York City, we've noticed that the carrier has already listed the BlackBerry Z10 on its website. It looks like the smartphone will be available for a $100 down payment with a $18 monthly installment for 24 months, though the UnCarrier also lists the BB Z10 for $532 up front. Notably, the handset's page says it supports 4G LTE -- and we imagine we'll hear a good deal more about T-Mobile's network plans when the event kicks off in just a bit.

Forget the War of 1812. How about a home whose historic foundation dates back a full century earlier that has just been listed for sale in Newark, N.J.? The Sydenham House was built in 1712 as a two-room saltbox over a root cellar and was later expanded in 1826. It's now a five-bedroom, two-bathroom residence with a distinct calling card: It's the oldest house in Newark and the oldest private residence in the metropolitan New York area.
The home has been refurbished to its original condition and modernized with amenities necessary for modern living. It has been listed since 1970 on the National Register of Historic Places. Sydenham House appears to have come a long way since 2005, when it was last on the real estate market and featured in The New York Times. At that time, the home was in rough shape, occupied only by a caretaker employed by descendants of a Newark couple who had for 40 years worked on preserving the residence. The home still retains its original floors, doors and hardware, windows and fireplaces, but has been bolstered with new wiring, plumbing, roof and gourmet kitchen.
The Times noted that the home had been listed for sale at $699,000 in 2005, which many neighbors deemed too high, especially because strict guidelines were set forth by its now-deceased owners regarding the way in which the house can be remodeled or maintained. Now, however, the home is priced at $438,000, though it still raises the question: How much value should be placed on a property for which there are no comparable homes?

Palm Sunday was far from calm Sunday in North Texas, as powerful winds gusting to 45 mph made temperatures in the 50s feel like the 40s.
But now that the wind has died down, it's time for the big chill.
The National Weather Service has issued a freeze warning for all of North and Central Texas from 2 a.m. to 9 a.m. Monday morning. Temperatures will fall into the upper 20s and low 30s before the start of the weekday rush hour.
So if you got a little ahead of yourself with spring gardening chores, beware: Cover up those tender plants overnight.
The weather service also urges you to make sure that automatic sprinkler systems are turned off to avoid the possibility of ice forming on roads, driveways and sidewalks.
High pressure will keep the forecast quiet for the beginning of the week; still cool with highs only in the upper 50s to low 60s.
Our next chance of rain may come on Thursday.

GARFIELD, N.J. (AP) -- The neighborhood looks exceedingly normal: single-family homes and apartment buildings packed together, dogs barking from postage-stamp-size lawns, parents hustling down narrow sidewalks to fetch their children from school. But something with very dangerous potential lies below the surface, officials say.
The residents' toenails will provide confirmation.
A plume of hexavalent chromium, a metal used in industrial production that the Centers for Disease Control and Prevention calls a "well-established carcinogen," has spread under Garfield, putting about one-tenth of the city's homes ? about 600 structures and 3,600 residents ? at risk.
The Environmental Protection Agency is about to start drilling on the spill site to determine how much chromium is pooled beneath and remove tainted soil. The agency is also testing the broader area to determine how it will be cleaned up. Now a group of scientists from New York University is working to assess how much chromium residents may have been exposed to.
Researchers will collect toenail clippings from city residents. The nails will be tested for traces of chromium. Because toenails grow slowly, it is possible to see how much chromium has accumulated in the body over the past 18 months or so, said Judith Zelikoff, a professor of environmental medicine at New York University.
"Our major goal is to try to relieve their fears," Zelikoff said. "With the economy, they can't sell their homes. They don't know if they got exposed."
The contamination started 30 years ago, when thousands of pounds of hexavalent chromium? the same stuff that sickened Californians whose story was told in "Erin Brockovich" ? leaked from a tank at the EC Electroplating Co., a factory surrounded on all sides by houses and apartments. The state started cleaning up the spill but stopped two years later. In 1993, chromium was found at a now-shuttered firehouse and later in homes.
The EPA designated the area as a Superfund site ? marking it as of the nation's most toxic uncontrolled hazardous waste sites ? in 2011, and officials cautioned residents to stay out of their basements to prevent potential chromium exposure. EPA officials removed chromium from the building and demolished it last year, and found that some tanks had holes in them, potentially releasing even more chromium into the groundwater.
Officials say the contamination has not affected the city's drinking water, which is drawn from an outside source. Instead, they worry that people could inhale chromium dust that has been found in basements where groundwater has leached in.
The chromium plume is about three-quarters of a mile wide and slightly more than an eighth-mile long, EPA officials said. The substance has traveled from the site underneath the Passaic River and into the city of Passaic. The agency has installed about 40 monitoring wells to monitor how far the metal has spread.
"We're trying to find out the extent of the plume," said Rich Puvogel, a project manager with the EPA.
High quantities of the metal have been found in 14 homes that have since been cleaned up. Trace amounts were found in 30 to 40 homes. Testing continues, and a nearby school did not show elevated chromium levels.
Cathy Garrone, who bought a house in the neighborhood in 1985, walked her small dog recently across the street from the site where the plant once stood, a lot now fenced off and peppered with mounds of rocks and dirt.
She said she wouldn't have bought there if she had known about the chromium spill, and thinks much more testing needs to be conducted, both of the environment and people.
"I'd like them to do more testing to assure my safety," she said.
The research study is being done in conjunction with the city of Garfield. Officials are hoping the testing can bring some answers to residents.
"It's just been left," Zelikoff said. "A lot of people made mistakes."
Zelikoff and her team hope to test as many as 250 residents; some must live close to the plume and others about 3 miles away as a control group. When residents sign up, they will be given a kit that contains stainless steel toenail clippers (cheap ones contain chrome), instructions on how to clip the nails (samples from all 10 are needed) and an envelope for the clippings. It will take weeks to know the results, and people will be advised by public health nurses and others once the results return.
Test subjects must be between 18 and 65, have lived in Garfield for at least two years, not take chromium supplements, and not smoke.
Many residents are immigrants and relative newcomers, and some don't know about the contamination, Zelikoff said. City officials are working to educate residents, disseminating information about the cleanup to local churches and in four languages: English, Spanish, Polish and Macedonian, said city manager Tom Dutch.
Dutch said an initial health consultation indicates that there's no higher incidence of cancer in the neighborhood than anywhere else in the city, but he thinks the issue needs additional scientific testing.
"I have some concerns," Dutch said. "There are residents who have come to meetings and said, 'This one died, that one died,' and I think it warrants further investigation."
CAMBRIDGE, Massachusetts (Reuters) - Harvard University will be stripped of four national quiz championship titles after organizers found a competitor from the Ivy League school inappropriately accessed information about questions used in the tournament.
The National Academic Quiz Tournaments said that a security review found that Harvard competitor Andy Watkins accessed pages on its administrative Website just before the 2009, 2010 and 2011 Intercollegiate Championship Tournaments or "Quiz Bowls".
"We can't have that happen," said Robert Hentzel, NAQT president said on Friday.
The quiz organizers said their review found that Watkins accessed Web pages that showed the first 40 characters of questions to be asked at the tournaments, though it said it had no direct or statistical evidence that Watkins and three others took advantage of their prior access in game situations.
Hentzel, the group's president, said sometimes even the first 40 characters of a question can be telling.
At the time of the review, Watkins was working for the quiz organizer as question writer for high-school level contests. The NAQT said Watkins has been terminated as a question writer.
Watkins denied any wrongdoing.
"My immaturity damaged my much-prized relationship with NAQT and cast undue doubt on three remarkable accomplishments by three Harvard teams," said Watkins, in a statement issued by the organization. "I regret my breaches of question security .... Though I know everyone will make their own judgments, I did compete in good faith."
A Harvard spokesman declined to comment on the news.
The academic setback for the prestigious New England school came a day after Harvard scored a rare athletic triumph -- winning its first-ever game in the national college basketball championships.
It follows an incident last year when dozens of students were forced to withdraw temporarily from the university after cheating on a final exam in the largest academic scandal to hit the nearly four-century-old school in recent memory.
The National Academic Quiz Tournaments said they would vacate all of Harvard's wins at the Division I events in 2009 through 2011 and recognize other teams as national champions.
It named the University of Minnesota as undergraduate champion in 2009; the University of Chicago as Division I champion in 2010; the University of Minnesota as Division I champion in 2011, and Virginia Commonwealth University as undergraduate champion in 2011.

Nobody's going to win an Emmy for a parody of the TV show "Star Trek" filmed by Internal Revenue Service employees at an agency studio in Maryland.?
Instead, the IRS got a rebuke from Congress for wasting taxpayer dollars.?
The agency says the video, along with a training video that parodied the TV show "Gilligan's Island," cost about $60,000. The "Star Trek" video accounted for most of the money, the agency said.
The IRS said Friday it was a mistake for employees to make the six-minute video. It was shown at the opening of a 2010 training and leadership conference but does not appear to have any training value.
The video features an elaborate set depicting the control room, or bridge, of the spaceship featured in the hit TV show. IRS workers portray the characters, including one who plays Mr. Spock, complete with fake hair and pointed ears.
The production value is high even though the acting is what one might expect from a bunch of tax collectors. In the video, the spaceship is approaching the planet "Notax," where alien identity theft appears to be a problem.
"The IRS recognizes and takes seriously our obligation to be good stewards of government resources and taxpayer dollars," the agency said in a statement. "There is no mistaking that this video did not reflect the best stewardship of resources."
The agency said it has tightened controls over the use of its production equipment to "ensure that all IRS videos are handled in a judicious manner that makes wise use of taxpayer funds while ensuring a tone and theme appropriate for the nation's tax system."
The agency also said, "A video of this type would not be made today."
The video was released late in the day Friday after investigators from the House Ways and Means Committee requested it.
"There is nothing more infuriating to a taxpayer than to find out the government is using their hard-earned dollars in a way that is frivolous," said Rep. Charles Boustany, R-La., chairman of the Ways and Means oversight subcommittee. "The IRS admitted as much when it disclosed that it no longer produces such videos."
The film was made at an IRS studio in New Carrollton, Md., a suburb of Washington. The agency said it uses the studio to make training films and informational videos for taxpayers.
"The use of video training and video outreach through the in-house studio has become increasingly important to the IRS to reach both taxpayers and employees," the agency said. "In the current budget environment, using video for training purposes helps us save millions of dollars and is an important part of successful IRS cost-efficiency efforts."
IRS YouTube videos have been viewed more than 5 million times, the agency said. A video on the IRS website called "When Will I Get My Refund?" has been seen 950,000 times this filing season.
The disclosure of the "Star Trek" video comes as agencies throughout the federal government face automatic spending cuts, including employee furloughs at many of them.
Acting IRS Commissioner Steven Miller has told employees they could be furloughed five to seven days this summer. The furloughs, however, will be delayed until after tax filing season so refunds should not be affected.
The agency said the "Star Trek" video "was a well-intentioned, light-hearted introduction to an important conference during a difficult period for the IRS."
Congressional investigators initially sought both the "Star Trek" video and the "Gilligan's Island" video but after viewing them determined that the "Gilligan's Island" video was a legitimate training video. The IRS did not release the "Gilligan's Island" video.
"The video series with an island theme provided filing season training for 1,900 employees in our Taxpayer Assistance Centers in 400 locations," the IRS said. "This example of video training alone saved the IRS about $1.5 million each year compared to the costs of training the employees in person."

Long-sought specificity on the shapes of serotonin binding sites could aid in the discovery of new drugs to combat depression, as well as in the study of consciousness
By Arran Frood and Nature magazine
Two studies have decoded the structure of two of the brain's serotonin receptors. Here shown is a receptor known as 1B with the migraine drug ergotamine (pink) locked into one of its binding pockets.Image: Chong Wang & Huixian Wu
Researchers have deciphered the molecular structures of two of the brain's crucial lock-and-key mechanisms. The two molecules are receptors for the natural neurotransmitter serotonin ? which regulates activities such as sleep, appetite and mood ? and could provide targets for future drugs to combat depression, migraines or obesity.?
?This is huge,? says Bryan Roth, a neuropharmacologist at the University of North Carolina Chapel Hill Medical School, and a co-author of the two studies published in Science today. ?Before this there was no crystal structure for any serotonin receptor. A lot of what was theoretical is now known with a great degree of certainty,? he says.
Scientists have been trying to decipher serotonin receptors for years. Armed with information on the atomic level, they might now be able to make breakthroughs in drug discovery and in understanding how the physical structures of the brain produce consciousness, says Roth.
Christoph Anacker, a neuropharmacologist at King's College London, agrees that the findings are important for drug discovery. ?These receptors are involved in so many conditions, especially depression, and knowing the molecular structures will help to develop more specific drugs and avoid the expression of undesired side effects.?
Chemical messengers There are 14 different known serotonin receptors. The molecules lie on the outer membranes of nerve cells; when drugs or neurotransmitters lock into the receptors from outside the cell, they trigger the release of other chemicals inside the cell. Those chemicals ? which can be different depending on what drug or neurotransmitter has triggered them ? activate further hormones and metabolites, producing signaling cascades that are ultimately responsible for many aspects of the way we feel, perceive and behave.
Some drugs bind at more than one receptor, setting off not-fully-understood reactions that can produce unwanted side effects. To avoid this, researchers want to fine-tune drugs so that they activate only the desired signaling pathway.
Roth and his colleagues uncovered the receptor structures using X-ray crystallography, in which X-ray beams are fired at crystals of the compound, and the structure is deduced from how the beams scatter.
The teams focused on two receptors, called 1B and 2B. They found that the molecules had very similar structures in the areas where serotonin docks.
But in one area of the 1B receptor, the binding pocket was wider than in the 2B receptor. Although the difference was a mere 0.3 nanometers, about the width of three helium atoms, the difference is enough to explain why the two receptors bind differently to certain compounds.
This distinction may be relevant to drug safety: some drugs that activate the 2B receptor have been thought to cause heart problems, and have been withdrawn as unsafe. The connection has earned the 2B the nickname of death receptor.
