King Richard III Bones Found, Scientists Say


The search for the long-vilified English King Richard III, who died in battle in 1485 and whose image as a nasty tyrant was immortalized by William Shakespeare, appears to have ended.

In a dramatic Monday morning press conference, researchers from England's University of Leicester announced they had identified "beyond all reasonable doubt" Richard III's skeletal remains. The remains had been unearthed last August by an archaeological team from beneath a parking lot where the friary that reportedly held Richard III's body once stood.

For nearly 40 minutes on Monday, a team of scientists and historians reported the results of detailed medical, historical, genealogical, and genetic studies conducted after archaeologists discovered a skeleton that they believed to be Richard III. (Related: "Shakespeare's Coined Words Now Common Currency.")

Turi King, a geneticist at the University of Leicester, and Kevin Schürer, a genealogist at the school, turned up the most compelling evidence. By poring over historical records and documents, Schürer conclusively identified two of Richard III's living descendants: Michael Ibsen, a furniture maker in London, England, and a second individual who now wishes to remain anonymous.

King took DNA samples from the two descendants and compared them to a sample of ancient DNA obtained from the skeleton from the friary. "There is a DNA match," King told reporters, "so the DNA evidence points to these being the remains of Richard III."

Richard III died at age 32 of injuries he sustained at the Battle of Bosworth in August 1485, and the new evidence fits closely with these records.

University of Leicester osteologist Jo Appleby showed two gruesome head injuries that Richard received in his last moments—one likely inflicted from behind by an assailant bearing a halberd, a medieval weapon consisting of an axe blade topped with a spike. In addition, Appleby found several other wounds that she described as "humiliation injuries," likely inflicted on Richard's dead body.

Historical accounts suggest that Richard's enemies stripped his body after the battle and threw his corpse over a horse "and this," says Appeleby, "would have left his body exposed to [humiliation] injuries."

The osteologist's studies also revealed that Richard was a man of slight build who suffered from a medical condition known as idiopathic adolescent scolosis, a curvature of the spine that developed after ten years of age and that may have brought back pain to the future king.

This emerging scientific picture of Richard fits with a description of the king written by John Rous, a medieval English historian, in the late 15th century. According to Rous, Richard III "was slight in body and weak in strength."

The King's enduring image as a cruel despot was cemented by Shakespeare, who portrayed him as a glowering monster so repugnant "that dogs bark at me as I halt by them."

In Shakespeare's famous play, the hunchbacked king claws his way to the throne and methodically murders most of his immediate family—his wife, older brother, and two young nephews—until he suffers defeat and death on the battlefield at the hands of a young Tudor hero, Henry VII.

Bug protects itself by turning its environment to gold









































Mythical King Midas was ultimately doomed because everything he touched turned to gold. Now, the reverse has been found in bacteria that owe their survival to a natural Midas touch.












Delftia acidovorans lives in sticky biofilms that form on top of gold deposits, but exposure to dissolved gold ions can kill it. That's because although metallic gold is unreactive, the ions are toxic.












To protect itself, the bacterium has evolved a chemical that detoxifies gold ions by turning them into harmless gold nanoparticles. These accumulate safely outside the bacterial cells.












"This could have potential for gold extraction," says Nathan Magarvey of McMaster University in Hamilton, Ontario, who led the team that uncovered the bugs' protective trick. "You could use the bug, or the molecules they secrete."












He says the discovery could be used to dissolve gold out of water carrying it, or to design sensors that would identify gold-rich streams and rivers.












The protective chemical is a protein dubbed delftibactin A. The bugs secrete it into the surroundings when they sense gold ions, and it chemically changes the ions into particles of gold 25 to 50 nanometres across. The particles accumulate wherever the bugs grow, creating patches of gold.











Deep purple gold













But don't go scanning streams for golden shimmers: the nanoparticle patches do not reflect light in the same way as bigger chunks of the metal – giving them a deep purple colour.












When Magarvey deliberately snipped out the gene that makes delftibactin A, the bacteria died or struggled to survive exposure to gold chloride. Adding the protein to the petri dish rescued them.











The bacterium Magarvey investigated is one of two species that thrive on gold, both identified a decade or so ago by Frank Reith of the University of Adelaide in Australia. In 2009 Reith discovered that the other species, Cupriavidus metallidurans, survives using the slightly riskier strategy of changing gold ions into gold inside its cells.













"If delftibactin is selective for gold, it might be useful for gold recovery or as a biosensor," says Reith. "But how much dissolved gold is out there is difficult to say."

How can Amy Poehler help Best Buy during the Super Bowl?



Can she help?



(Credit:
Best Buy/YouTube Screenshot by Chris Matyszczyk/CNET)


In the first quarter of today's Big Game featuring big people doing big things to each other, Amy Poehler will be trying to do big things for Best Buy.


Unlike the players -- who will probably be tied 3-3 in a dull defensive battle when Amy appears -- Poehler has one shot to give the Best Buy brand a shot in arm. Or perhaps a shot at redemption.


Best Buy has been crossing some turbulent oceans recently, so securing the services of one of America' funniest actors is a pleasant coup.


The company has released a sneak preview (embedded here) of Poehler asking questions that are sweetly self-referential, so it may be that this theme will continue during today's spot.



More Technically Incorrect



The idea seems to be that whatever questions you have, those nice people in blue polo shirts will have the answer for you.


In order to reinforce this dream, Best Buy has co-opted the hashtag #infiniteanswers on Twitter.


Naturally, there have already been slight setbacks with this strategy.


For example, a twitterer called Jonathan has already offered: "#infiniteanswers not at your Willimar MN location I have seen smarter things come out of a dead animal."


Worse, another tweeter, Billy Byler seemed to be experiencing a little humorous bile: "Every answer was 'Not sure. Check Amazon.' @BestBuy: Amy Poehler visited us & had A LOT of questions. http://youtu.be/PcmW8HCuLo8 #infiniteanswers."


Can you win them over, Amy? Can you?

Pictures We Love: Best of January

Photograph by Dieu Nalio Chery, AP

The magnitude 7 earthquake that struck near Port au Prince, Haiti, in January 2010 so devastated the country that recovery efforts are still ongoing.

Professional dancer Georges Exantus, one of the many casualties of that day, was trapped in his flattened apartment for three days, according to news reports. After friends dug him out, doctors amputated his right leg below the knee. With the help of a prosthetic leg, Exantus is able to dance again. (Read about his comeback.)

Why We Love It

"This is an intimate photo, taken in the subject's most personal space as he lies asleep and vulnerable, perhaps unaware of the photographer. The dancer's prosthetic leg lies in the foreground as an unavoidable reminder of the hardships he faced in the 2010 earthquake. This image makes me want to hear more of Georges' story."—Ben Fitch, associate photo editor

"This image uses aesthetics and the beauty of suggestion to tell a story. We are not given all the details in the image, but it is enough to make us question and wonder."—Janna Dotschkal, associate photo editor

Former SEAL Killed at Gun Range; Suspect Arrested













A man is under arrest in connection with the killing of former Navy SEAL and "American Sniper" author Chris Kyle, the most deadly sniper in U.S. history, and another man at an Erath County, Texas, gun range, police said.


"We have lost more than we can replace. Chris was a patriot, a great father, and a true supporter of this country and its ideals. This is a tragedy for all of us. I send my deepest prayers and thoughts to his wife and two children," "American Sniper" co-author Scott McEwen said in a statement to ABC News.


ABC affiliate WFAA-TV in Dallas reported that Kyle and a neighbor of his were shot while helping a soldier who is recovering from post traumatic stress syndrome at a gun range in Glen Rose.


The suspect, identified as Eddie Routh, 25, was arrested in Lancaster, Texas, after a brief police chase, a Lancaster Police Department dispatcher told ABC News.


Routh was driving Kyle's truck at the time of his arrest and was held awaiting transfer to Texas Rangers, according to police.


Investigators told WFAA that Routh is a former Marine said to suffer from post-traumatic stress syndrome.


Authorities identified the other man who was killed with Kyle as 35-year-old Chad Littlefield.

PHOTOS: Notable Deaths in 2013


Kyle, 38, served four tours in Iraq and was awarded two Silver Stars, five Bronze Stars with Valor, two Navy and Marine Corps Achievement Medals, and one Navy and Marine Corps Commendation.


From 1999 to 2009, Kyle recorded more than 150 sniper kills, the most in U.S. military history.


After leaving combat duty, Kyle became chief instructor training Naval Special Warfare Sniper and Counter-Sniper teams, and he authored the Naval Special Warfare Sniper Doctrine, the first Navy SEAL sniper manual. He left the Navy in 2009.


"American Sniper," which was published last year in 2012, became a New York Times best seller.


Kyle was also an advocate for his fellow service members suffering from PTSD, creating a foundation to help with their treatment.


Travis Cox, the director of FITCO Cares, the non-profit foundation Kyle established, said Kyle's wife Taya and their children "lost a dedicated father and husband" and the country has lost a "lifelong patriot and an American hero."


"Chris Kyle was a hero for his courageous efforts protecting our country as a U.S. Navy SEAL during four tours of combat. Moreover, he was a hero for his efforts stateside when he helped develop the FITCO Cares Foundation. What began as a plea for help from Chris looking for in-home fitness equipment for his brothers- and sisters-in-arms struggling with Post Traumatic Stress Disorder (PTSD) became an organization that will carry that torch proudly in his honor," Cox said in a statement.


The fatal shooting comes after week filled with gun-related incidents, as the national debate heats up on what to do about gun violence.


In the past week, a teen who participated in President Obama's inaugural festivities was shot to death in Chicago, a bus driver was fatally shot and a 5-year-old was taken hostage in Alabama, and a Texas prosecutor was gunned down outside a courthouse.

Two worms, same brains – but one eats the other



































IF TWO animals have identical brain cells, how different can they really be? Extremely. Two worm species have exactly the same set of neurons, but extensive rewiring allows them to lead completely different lives.












Ralf Sommer of the Max Planck Institute for Developmental Biology in Tübingen, Germany, and colleagues compared Caenorhabditis elegans, which eats bacteria, with Pristionchus pacificus, which hunts other worms. Both have a cluster of 20 neurons to control their foregut.












Sommer found that the clusters were identical. "These species are separated by 200 to 300 million years, but have the same cells," he says. P. pacificus, however, has denser connections than C. elegans, with neural signals passing through many more cells before reaching the muscles (Cell, doi.org/kbh). This suggests that P. pacificus is performing more complex motor functions, says Detlev Arendt of the European Molecular Biology Laboratory in Heidelberg, Germany.












Arendt thinks predators were the first animals to evolve complex brains, to find and catch moving prey. He suggests their brains had flexible wiring, enabling them to swap from plant-eating to hunting.

Golf: Double eagle joy puts Gallacher in Dubai lead






DUBAI: Stephen Gallacher fired two eagles on the back nine in a remarkable bogey-free round of 10-under par 62 to take a three-shot lead into the final day of the $2.5 million Omega Dubai Desert Classic.

Gallacher, nephew of the former European Ryder Cup captain Bernard, rattled the pin with his second shot on the par-5 13th and then holed his bunker shot on the 18th from 30 yards.

That, along with six other birdies, helped him reach 21-under par 195 after three rounds.

The 195 total of the 38-year-old Scotsman was one better than the tournament record of 20-under par set by Tiger Woods during his first visit to the UAE in 2001.

The lowest winning total in the tournament is 22-under par by Thomas Bjorn that same year.

South Africa's Richard Sterne, leader after the first two days at 12-under par, added a solid third round of six-under par 66, but could only watch in astonishment as Gallacher sped past him.

Two shots behind Sterne's 198 was rising Danish star Thorbjorn Olesen (67), while Chile's Felipe Aguilar (66) and India's Jeev Milkha Singh (67) were tied for the fourth place at 14-under par 202.

World No8 Lee Westwood made a charge with a 66 that moved him to ninth place at 204, nine shots behind the leader, while No14 Sergio Garcia could only add a 71 to tie for 19th place at 206.

Defending champion Rafael Cabrera-Bello shot a third successive round of 69.

Gallacher, who shot a 63 on the opening day and has finished second and 10th the previous two years in the tournament, said: "I just think I've played this golf course a lot of times.

"I've come out on holiday here and I am quite familiar with the course. I came here over Christmas and a couple days earlier before the start of the season.

"You know your way around here, the lines, you know where to hit it and where not to hit it. It's obviously in great condition and kind of suits my eye as well.

"I'm excited and looking forward to tomorrow. I struggled last week in Doha and found out that my driver had a hairline crack. With the new one, I'm hitting more fairways and I've putted really good. On these courses, you have got to be hitting from the fairways."

While Gallacher, ranked 111th in the world, is looking for his first win since the 2004 Alfred Dunhill Links Championship, his good friend Sterne is hoping end a title drought that started in early 2009.

"I'm quite happy. The weather was a bit dodgy in the beginning, but the weather kind of came around and it wasn't too bad," said 165th-ranked Sterne.

"The conditions are pretty good. As you can see, a couple of good scores. You know, shooting 66 and I'm three behind, which unfortunately can happen in this game."

"I've given myself a chance going into tomorrow, in the last group again which will be hopefully a lot of fun and put some good scores on there and put some pressure on Stephen."

Forty years ago, the Ohm F speaker was a game-changer; it still is



The Ohm F speakers



(Credit:
Ohm)


Lincoln Walsh died a year before his radically innovative speaker technology made its commercial debut in the Ohm Acoustics F in 1972. The speaker featured an omnidirectional Walsh driver that projected a massive stereo soundstage. At the time of its introduction the $900 per pair Ohm F was hailed as one of the greatest speakers of all time by the international press. It sounded like nothing else, and the single 12-inch, truncated cone driver produced bass, midrange and treble frequencies (37Hz to 17kHz). The driver had a titanium top section, aluminum midband and paper bottom, with a single voice-coil at the top of the driver. Even today, bona-fide full-frequency drivers like that are rare. The Ohm drivers and cabinets were made in Brooklyn.


According to Ohm's President John Strohbeen, the early production Fs had "functionality issues." "They needed 300 watts to get going, and 301 to blow them up," Strohbeen said with a chuckle. Ohm couldn't repair them, so they replaced broken drivers under warranty. The engineers kept redesigning the driver to improve reliability, but it was the introduction of ferrofluid-cooled voice coils that cured the F's reliability woes.


Unlike box speakers that project sound forward, the F radiated bass, midrange and treble frequencies in a full 360-degree pattern. The sound quality was so far ahead of what was available from conventional box speakers the F remained in production for 12 years, until 1984, but by that time the price had more than quadrupled to $3,995 per pair!


The Ohm Acoustics factory is still in Brooklyn, and still offers factory upgrades on the F speakers. That's remarkable -- how many companies do you know that still service 40-year-old products -- but that's what separates high-end audio from mainstream gear. Ohm currently offers a complete line of Walsh omni-directional speakers, with prices starting at $1,400 per pair. Ohm sells factory direct, with a very generous 120-day home trial period.
