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.

Sneaky ninja robot silently stalks its prey








































MOVE over David Attenborough. A robot that moves only when it won't be seen or heard might make it easier to sneak up on animals and film them in the wild.












Defence labs have built robots that track people through cities, avoiding well-lit areas. But cities are noisy, so if a robot keeps a certain distance it's unlikely to be heard. Tracking and filming animals in the wild is tougher because they often have keen hearing and the environment is usually quieter. Matthew Dunbabin and his collaborator Ashley Tewes at the CSIRO Autonomous Systems Laboratory in Brisbane, Australia, are teaching a four-wheeled robot to move only when intermittent sounds - like bird or frog calls - will mask its movements.













In tests, the robot picked up the sounds of things like fork-lifts, cellphones and birds, and was able to predict whether they were likely to persist long enough to cover its movement. The robot can also identify its own noise, and guess how it will vary at different speeds and turning angles - calculating what this will sound like to a target up to 50 metres away.












With the help of a camera, laser scanner and the right algorithm, the robot can figure out which vantage points will provide the best cover so it can skulk in the shadows.

1964 Ears custom in-ear headphones beat their competition on price



1964 Ears 1964-V6 headphones, with custom art faceplates

Steve Guttenberg/CNET)



1964 Ears makes custom-molded, in-ear headphones, just like Ultimate Ears, JH Audio, and Westone, but 1964 Ears is a relative newcomer. It has to try harder than the more established brands, so 1964 Ears offers a wider array of customizable features and service options than the others. Prices start a little lower, at $350 for the 1964-D, and $650 for the top-of-the-line model I'm reviewing here today, the 1964-V6. That's significantly less expensive than the established brands' flagships.


1964 Ears can also "remold" your old universal-fit balanced-armature headphones, like a Shure or Etymotic pair, and make them into custom-molded-to-your-ears headphones for $250. 1964 Ears will also remold older custom-molded in-ear headphones, so you could buy someone's older Ultimate Ears or Westone headphones, and have them remolded to fit your ears. I don't know of another company that offers that service.


Manufacturing in-ear headphones is a labor-intensive process, and 1964 Ears builds all of its headphones in Portland, Ore. The company has an excellent video that takes the mystery out of the process. Watch it and you'll see that few consumer products priced like in-ear headphones are built with this much attention to detail. Since they're made to order, many custom features are available, including different colors for the earpieces, and wood, metal, or carbon-fiber end caps. You can even supply your own artwork; my 1964-V6s have a snazzy black-and-white checkerboard pattern. 1964 Ears also offers soft plastic ear canal fittings that improve comfort over the standard hard acrylic earpieces. Replacement cables sell for $32.

The 1964-V6 is a "three-way" design with six balanced-armature drivers (dual bass, dual midrange, and dual treble). The headphone comes with your choice of a 50- or 64-inch detachable cable and two carrying cases. Before you buy custom-molded in-ear headphones you need to first visit a local audiologist to have "impressions" of your ear canals made, which are then used to build your headphones. Most audiologists charge from $75 to $100 to make the molds, but you can't beat custom in-ears for fit and isolation from external noise.



In terms of sound, the V6 is certainly on par with the best Ultimate Ears, Jerry Harvey, and Westone custom-molded in-ears. The tonal balance is nice and smooth, bass power and detail are excellent, and the treble is crisp. I spent a few weeks using the 1964-V6s instead of my more expensive customs, and thoroughly enjoyed them.


To gain more perspective on the sound I compared the V6 earphones with the $400 Logitech UE 900 universal-fit headphones. I like the UE 900s a lot, and they use similar balanced armature drivers to the V6 model's, but the UE 900 earphones aren't custom-molded. So the fit is less secure and they don't block outside noise as well as the V6s do. Sonically, the V6 earphones were substantially more detailed and clear. I didn't have to switch back and forth too many times; the V6s resolved details in the mixes better, so I could more clearly hear exactly how much reverb was used on each instrument in the mix. The V6 earphones had superior dynamic punch, while the UE 900s seemed more laid-back by comparison.


The 1964-V6 earphones are really good, but the latest $1,099 Jerry Harvey JH13 customs are better. Again it's a matter of clarity, and the JH13s produced a bigger and more spacious stereo image. Percussion instruments cut through better, cymbals shimmered more, bass was richer, and vocals had more body. Still, the 1964-V6 earphones weren't embarrassed by the almost-twice-as-expensive JH Audio JH13 pair. That's impressive.

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 a former Navy SEAL and "American Sniper" author Chris Kyle 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.

The other man who was killed with Kyle was identified as 35-year-old Chad Littlefield by authorities.


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.


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.


After leaving combat duty, 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.


The fatal shooting comes after week filled with gun related incidents -- a teen who participated in inaugural festivities was shot to death in Chicago, a bus driver was fatally shot and 5-year-old was taken hostage in Alabama and a Texas prosecutor was gunned 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.

Colonial flags fly in Hong Kong as anger grows






HONG KONG: Sixteen years after Hong Kong returned to Chinese rule, public discontent with Beijing is swelling and protesters have been rallying around an unexpected symbol - the British colonial flag.

Tens of thousands have taken to the streets in recent months in marches against Chief Executive Leung Chun-ying, who took over from Donald Tsang last July after being elected by a 1,200-strong pro-Beijing committee.

On several occasions the old blue flag, which incorporates the Union Flag, has been flown by protesters on the streets of what is becoming an increasingly divided Hong Kong, both embarrassing and infuriating Beijing.

While Leung's supporters say he is tackling pressing social issues such as affordable housing and the strain on public services, his critics see him as a stooge for Beijing and are angry over a widening poverty gap.

In September, he backed down from a plan to introduce Chinese patriotism classes in schools, which had incited mass protests and was viewed as an attempt to brainwash children into accepting doctrines taught on the mainland.

The founder of a group mobilising Hong Kongers to fly colonial flags said it did so because the city was worse off after 16 years of "encroachment" by Beijing, stressing it was not because of any desire to see Britain rule again.

"Our freedom and everything else has gone downhill since (the handover)" said 26-year-old Danny Chan from the "We're Hong Kongese, not Chinese" Facebook group, which has been "liked" by nearly 30,000 people.

Hong Kong's semi-autonomous status enshrines civil liberties not seen on the mainland, including the right to protest, until 2047 under the "One country, two systems" handover agreement.

Chan cited housing prices that stubbornly remained among the world's highest and the widening income gap between the rich and the poor as factors driving the increasingly frequent protests in the city.

Many Hong Kongers blame increased immigration from the mainland for high house prices and overcrowding in local hospitals.

Chan said that the flags symbolised anger and the perceived erosion of the rule of law in Hong Kong since 1997.

"Hong Kong's core values and the rule of law have been gradually destroyed until there is almost nothing left," argued the computer engineer, who waved the flag at a mass rally on January 1 to demand Leung step down.

Dixon Sing, political analyst at Hong Kong's University of Science and Technology, said the protesters "believe the Chinese Communist Party has been undermining those core values and reneging on the promise of giving Hong Kong 'two systems'".

The increased visibility of the old emblem has sparked tensions, at a time when China is ushering in a new batch of leaders who yearn for order and stability in the Asian financial hub.

The British Council, which promotes cultural and educational ties overseas, unwittingly became embroiled in the controversy recently when advertisements for an education fair bearing the Union Jack became the centre of attention.

Comments such as "Great Britain built Great Hong Kong!" were posted on the British consulate's Facebook page and linked to the posters.

The advertisements were hastily removed due to the possibility of "misinterpretation", a British Council spokeswoman said.

The waving of the old flag has drawn criticism from Chen Zuoer, the former No.2 mainland Chinese official in Hong Kong, who reportedly said last year that it "should be sent to history museums".

Other critics, including those from the city's pro-democracy political camp, said any "good old days" notion is largely misguided, as corruption and malpractice were once widespread before a major clean-up in the 1970s.

"During colonial times, there was no freedom and our rights were denied but in the late 1980s, the government won people's trust and it was seen as clean," said Avery Ng from maverick lawmaker "Long Hair" Leung Kwok-hung's League of Social Democrats party.

The party has called for full democracy in Hong Kong to replace the current system.

"I understand the current sentiment but this is very sad for Hong Kong that people would rather look back at colonial times."

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.
