Mexican journalists march against attacks on press

Journalists march together during a protest to demand justice in the Regina Martinez case, a journalist killed a year ago and an end to more recent attacks on the press in Veracruz, Mexico, Sunday April 28, 2013. Journalists in several states organized a demonstration on Sunday to mark the first anniversary of the murder of Regina Martinez, a correspondent of the magazine Proceso. Attacks have become so common that many Mexican news media have announced they will no longer cover stories related to drug cartels.The issue has become so serious that Mexico's congress passed a bill this month that would allow journalists to request that federal prosecutors and federal judges investigate attacks on them, and would make federal intervention mandatory in some cases.

(AP) ? Officials in Veracruz state say they know who killed Regina Martinez. The muckraking reporter, found beaten and suffocated in her house, was just the victim of a robbery, according to prosecutors and a local court.

But many of her colleagues don't believe it. The man convicted of the crime was tortured into a confession, they allege. And the magazine she works for says state officials discussed sending police across the country in an attempt to hunt down and seize another reporter who raised questions about the death, which is one of a growing list of killings that have put Mexico among the most dangerous places in the world to be a journalist.

Some 400 people gathered Sunday in the center of Veracruz's state capital, Xalapa, for a march to demand justice in the Martinez case and an end to attacks on the press. Many held up posters suggesting the government had a hand in the case, some describing it as "a state killing." Dozens also protested in Mexico City.

The New York-based Committee to Protect Journalists said in a February report that 12 Mexican journalists went missing in 2006-2012 and 14 were killed because of their work. Mexico's federal Human Rights Commission lists 81 journalists killed since 2000.

Martinez was the Xalapa correspondent for Proceso, one of Mexico's most respected investigative newsmagazines, and she was one of the few in the state who continued to work on stories related to drug cartels. Her last story for the magazine was about the arrest of nine police officers accused of links to traffickers.

State officials accused a man named Jorge Antonio Hernandez Silva of taking part in the killing, saying it came during a robbery, and he was sentenced this month to 38 years in prison. But he asserted he was forced to confess through several days of torture, and Proceso's editors don't believe the killing has been solved, noting that none of the fingerprints found at the scene of the killing match those of Hernandez Silva.

"Those who are truly guilty have not been identified," the magazine said in an online statement.

Mike O'Connor, Mexico representative for the Committee to Protect Journalists, said federal officials have doubts, too.

"The federal government is not convinced that Hernandez Silva is guilty because a very active investigation by the federal government is continuing," he said.

Proceso issued a statement this month alleging that some current and former state officials had met to plan the capture of a reporter who questioned the verdict and "to do him harm if he resists." Veracruz Gov. Javier Duarte later met with editors of Proceso and promised an exhaustive investigation.

His Gulf coast state, plagued by clashes among powerful drug cartels, has been one of the most dangerous for journalists. Twelve reporters have been slain or gone missing there since the start of 2010, according to the Committee to Protect Journalists.

Less than a week after Martinez was slain, three local reporters were dismembered, stuffed into black plastic bags and dumped into a waste canal, apparently by people linked to drug gangs that demand either favorable coverage or none at all.

Among those still missing is Sergio Landa Rosado, who vanished on Jan. 23, his first day back at work at Diario Cardel in the town of Cardel after being away for more than a month because of an earlier kidnapping that followed his reporting on the slaying of a taxi driver.

Attacks have become so common that many Mexican news media have announced they will no longer cover stories related to drug cartels.

As in the case of Martinez, it often can be difficult to determine whether a killing is directly related to a reporter's work, and who might be responsible. Press rights groups say officials are often sluggish in trying to answer those questions, and few of the slayings have led to convictions.

The hacked-up body of 22-year-old photojournalist Daniel Martinez Bazaldua and that of another young man were found in the northern Mexico city of Saltillo on April 24.

Coahuila state officials said signs left at the scene suggested the two men had deserted from a drug gang and state Attorney General Homero Ramos told reporters later that investigators had testimony indicating both men "were participating in illegal activities."

Editors at Martinez Bazaldua's newspaper, Vanguardia, said state officials provided no evidence that the photographer, at least, had any links to drug gangs.

"We think it is sad and alarming that Coahuila has become a state in which the authorities condemn murdered people, converting them into criminals, without offering the least evidence," the newspaper wrote.

The issue has become so serious that Mexico's congress passed a bill this month that would allow journalists to request that federal prosecutors and federal judges investigate attacks on them, and would make federal intervention mandatory in some cases. It has been sent to the president for his signature.

Better fuel economy matters to more US consumers, survey finds

US consumers appear to be latching onto the drive for fuel economy, with almost 3 in 5 saying it will be a 'very important' factor in the next vehicle they buy, a survey shows.

By Mark Clayton,?Staff writer / April 29, 2013

Subaru Foresters are lined up at Twin City Subaru in Berlin, Vt., in February. US consumers appear to be latching onto higher mileage standards and to vehicles that sip rather than slurp gasoline in the next vehicle they buy, a survey shows.

America?s transition is well under way to higher mileage standards and to vehicles that sip rather than slurp gasoline, with manufacturers and consumers both supporting the shift, according to new research by the Consumer Federation of America.

Just six months ago, the federal government finished a plan to boost fuel economy standards of new cars to an average of 54.5 miles per gallon (m.p.g.) by 2025, up from 35 m.p.g. in 2017. Those mileage increases were?authorized under the Energy Independence and Security Act?passed by Congress in 2007.

Unknown, however, was how quickly automakers would shift production to go after those targets ? and whether consumers would accept higher vehicle prices up front in exchange for lower gasoline costs over the lifespans of their vehicles. In a first cut at answering those questions, the CFA polled consumers and analyzed fuel efficiency of new vehicles, including plug-in vehicles.

It found a shift in consumer sentiment and manufacturer output, including the following:

?A large majority of Americans support the higher fuel-economy standards approved by Congress and amplified by the Obama administration. Today's consumers say they expect the next vehicle they buy to get many more miles to the gallon than their current vehicles, the CFA survey found.

?Automakers are boosting average vehicle mileage of their fleets, while making a range of options available. At the same time, consumers have increasingly purchased more efficient vehicles, four years of automaker data show.

?Sales of electric vehicles, still new on the market, are outpacing sales of hybrid vehicles at a similar point in their introduction to market.

Most Americans support federal requirements to increase fuel economy, national polls conducted for the CFA found. Eighty-five percent back them, with 54 percent saying they strongly support the standards. Respondents' political affiliation didn?t seem to matter much, with 77 percent of self-described Republicans, 87 percent of Independents, and 92 percent of Democrats supporting the increase in mileage standards.

Moreover, 88 percent of those polled say a vehicle's fuel economy will be an important factor when they next shop for an automobile (for 59 percent, it's a ?very important? factor), the poll found. The general expectation is that the next vehicle a buyer purchases will get much better mileage than his or her current vehicle. Owners of cars that get 24 m.p.g., for instance, expect 31 m.p.g. next time.

LG will launch the world's first 55-inch curved OLED HDTV

LG will launch the world's first 55inch curved OLED HDTV

We visited LG's HQ earlier this month and heard that the curved OLED HDTV prototypes it showed at CES are due for release, and now it's official. A Korean press release indicates we can expect the 55EA9800 to launch in the next month, with shipments starting in June. According to the specs, its 4.3mm depth results in a weight of just 17kg, probably thinks to a carbon-fiber reinforced frame. Like an IMAX theater screen, the edges are curved towards the viewer to provide a more immersive feeling. Given the fact that we're still waiting for LG's flat OLED TVs to see a wider release we doubt it will arrive on US shelves any time soon, but until then you can check out our in-person pics from CES below, and a video after the break.

History, Science and the History of Science

Oxford, the city and the university, ooze with prestige. The city boasts more than a thousand years of learned history and is led by a Lord Mayor, rather than simply a Mayor. The university besieged me with momentous locations, such as the place where Robert Boyle discovered Boyle?s law in the seventeenth century and the track where Roger Bannister ran the first sub-four-minute mile in 1954.

In addition to being of high repute, when I visited Oxford during University of Wisconsin ? Madison?s spring break, I discovered the city and university to also be surprisingly accessible. The museums, the libraries, the colleges?you don?t have to stand and gaze admiringly at their outer walls, you can walk right inside for a couple pounds or, in many cases, for free. When, on my first day touring the town, I saw the sign announcing: Museum of the History of Science. Open. Free Admission. I glanced at the bearded busts towering over the wrought-iron entrance, thanked them for my good fortune, and walked into three floors of contraptions and charmingly outdated assumptions. The Museum of the History of Science is a curiosity shop full of astrolabes, microscopes, and other finely-tuned instruments that helped their owners measure things about the world.

If you?re in town, I recommend the stop. Depending on your discipline, you may be drawn to particular areas of the museum. But regardless of specialty, all visitors should check out the following Museum of the History of Science experiences:

Experience #1: Inspecting King George III?s microscope.

Made of silver circa 1770, the microscope is part sculpture, part instrument. While leaning forward to view a magnified specimen, any user of George III?s microscope would nearly touch foreheads with the two sculpted figures standing over the eyepiece. One could imagine King George III straightening up from a short bout at the microscope and turning to the latest copy of Opulent Scientist.

Besides King George III?s silver scope, for the microscope junky, the Museum of the History of Science is a treasure. According to the museum?s website, their collection includes ??microscopes from the earliest types used by Anton von Leeuwenhoek and Robert Hooke to the more elaborate ones of the nineteenth century.? See the slideshow at the end of this post for another photo highlighting the many ways to magnify our world.

Experience #2: Standing awestruck before Einstein?s blackboard.

You can stand and stare at the chalk marks made by Albert Einstein?s own hand in 1931. The board hangs on a wall in the museum?s lower floor, preserving the equations he wrote to explain how to model the expansion of the universe to Oxford scholars. Einstein visited University of Oxford in May 1931 to give a series of three lectures, he used this board to demonstrate the concepts discussed in the second lecture. The sign displayed with the blackboard helps viewers decipher the chalkmarks: ?The first three lines establish an equation for D, the measure of expansion in the universe. The lower four lines provide numerical values for the expansion, density, radius and age of the universe.?

Experience #3: Giving a moment of respectful silence to the people who recovered penicillin patient urine.

The row of three small glass vials with white metal twist caps and their reddish brown contents summarize countless hours of effort and prolonged life. You can view the actual penicillin produced by medical researchers in the early 1940s at Oxford while executing their groundbreaking work to make the drug widely available during wartime. The vial on the left holds the kind of penicillin that was initially used for medical purposes and required hundreds of cultures to produce. In the middle, a vial holds the remains of a more refined penicillin that researchers produced after seeking ways to minimize contamination. On the left is a vial of penicillin that was collected from a patient?s urine, recovery efforts that demonstrate the high value of penicillin antibiotics to mid-century medicine.

Many other treasures line the display cases in the Museum of the History of Science. When I visited, their rotating exhibition was on meteorology. One meteorological item on view was an 1851 datalog whose placard noted the log?s value and, for me, summarized the purpose of the museum. The log and the entire museum embody scientists? ??extraordinary devotion to the value of the data, and an ambition to realize its full value.?

Samsung profit at record high on smartphone boost

(AP Photo/Ahn Young-joon)

(AP) ? Samsung Electronics Co. said Friday its first quarter profit jumped to a record high as smartphone sales remained strong despite the impending launch of an updated version of its flagship Galaxy phone.

Sales of consumer electronics usually slow in the first three months of the year after the holiday shopping season, an effect that analysts thought would be compounded by the April release of the Galaxy S4 smartphone since many delay buying until the newest model is available. Apple Inc. has cited the upcoming release of a new iPhone model as a reason for a slowdown in sales of older models.

Samsung began sales of the S4 in its home South Korean market Friday and starts U.S. sales on Saturday. Analysts expect Samsung's profits to reach new highs in the second and third quarters if S4 sales are strong. Lee Don-Joo, head of sales and marketing at Samsung's mobile division, said sales of the S4 will outdo its predecessor, the Galaxy S III.

Samsung said January-March net profit surged 42 percent to 7.2 trillion won ($6.5 billion) from 5 trillion won a year earlier. That increase was despite booking a one-time charge against earnings related to settlement of its intellectual property battle with Apple. Analysts estimated the charge at $600 million.

Sales rose 17 percent to 52.9 trillion won. Operating profit was up 54 percent to 8.8 trillion won, in line with its preliminary results released earlier this month.

Profit was up 2 percent from the previous quarter's result, beating market expectations for a fall. Sales of the S III smartphone and the oversized handset called the Galaxy Note remained strong and shored up profit, Samsung said. It also spent less on marketing its mobile devices than it did in the previous quarter when competition heated up.

Samsung's IT and Mobile Communications division that makes smartphones, tablets, PCs and cameras reported 6.51 trillion won in operating income for the first quarter, up 56 percent from a year earlier and its highest since Samsung reorganized the division to merge PC and handset departments.

Samsung capitalized on global demand for smartphones with a range of mobile devices that come in a variety of screen sizes and prices, outpacing rivals including Apple Inc. and Nokia Corp.

As the S4 goes on sales several months before rival Apple introduces a new version of iPhone, analysts said Samsung's streak of record-setting profit will not stop any time soon.

"You can say it is like a snowball is rolling," said James Song, head of technology at Daewoo Securities. Song forecast Samsung's second quarter operating income to surpass 10 trillion won ($9 billion).

Market research firm IDC estimated that Samsung shipped 70.7 million smartphones during the first quarter, up 61 percent over a year earlier and capturing 33 percent market share. Apple, the second-largest smartphone maker, sold 37.4 million iPhones. Its market share fell to 17 percent from 23 percent a year earlier, IDC said.

The company's strong performance in the mobile market helped offset sluggish demand for TVs and a still weak recovery in display panel sales.

Samsung, based in Suwon, South Korea, is also the world's largest maker of memory chips, televisions, mobile handsets and liquid crystal display panels.

Scientists image nanoparticles in action

Apr. 25, 2013 ? The macroscopic effects of certain nanoparticles on human health have long been clear to the naked eye. What scientists have lacked is the ability to see the detailed movements of individual particles that give rise to those effects.

In a recently published study, scientists at the Virginia Tech Carilion Research Institute invented a technique for imaging nanoparticle dynamics with atomic resolution as these dynamics occur in a liquid environment. The results will allow, for the first time, the imaging of nanoscale processes, such as the engulfment of nanoparticles into cells.

"We were stunned to see the large-ranged mobility in such small objects," said Deborah Kelly, an assistant professor at the Virginia Tech Carilion Research Institute. "We now have a system to watch the behaviors of therapeutic nanoparticles at atomic resolution."

Nanoparticles are made of many materials and come in different shapes and sizes. In the new study, Kelly and her colleagues chose to make rod-shaped gold nanoparticles the stars of their new molecular movies. These nanoparticles, roughly the size of a virus, are used to treat various forms of cancer. Once injected, they accumulate in solid tumors. Infrared radiation is then used to heat them and destroy nearby cancerous cells.

To take an up-close look at the gold nanoparticles in action, the researchers made a vacuum-tight microfluidic chamber by pressing two silicon-nitride semiconductor chips together with a 150-nanometer spacer in between. The microchips contained transparent windows so the beam from a transmission electron microscope could pass through to create an atomic-scale image.

Using the new technique, the scientists created two types of visualizations. The first included pictures of individual nanoparticles' atomic structures at 100,000-times magnification -- the highest resolution images ever taken of nanoparticles in a liquid environment.

The second visualization was a movie captured at 23,000-times magnification that revealed the movements of a group of nanoparticles reacting to an electron beam, which mimics the effects of the infrared radiation used in cancer therapies.

In the movie, the gold nanoparticles can be seen surfing nanoscale tidal waves.

"The nanoparticles behaved like grains of sand being concentrated on a beach by crashing waves," said Kelly. "We think this behavior may be related to why the nanoparticles become concentrated in tumors. Our next experiment will be to insert a cancer cell to study the nanoparticles' therapeutic effects on tumors."

The team is also testing the resolution of the microfluidic system with other reagents and materials, bringing researchers one step closer to viewing live biological mechanisms in action at the highest levels of resolution possible.

The study appeared in the April 14 print edition of Chemical Communications in the article "Visualizing Nanoparticle Mobility in Liquid at Atomic Resolution," by Madeline Dukes, an applications scientist at Protochips Inc. in Raleigh, N.C.; Benjamin Jacobs, an applications scientist at Protochips; David Morgan, assistant manager of the Cryo-Transmission Electron Microscopy Facility at Indiana University Bloomington; Harshad Hegde, a computer scientist at the Virginia Tech Carilion Research Institute; and Kelly, who is also an assistant professor of biological sciences in the College of Science at Virginia Tech.

New 'Fairy' Insect Is Mind-Blowingly Small

A new species of tiny fly named after the fairy in "Peter Pan" is mind-blowingly miniscule, with delicate wings trimmed in fringe.

Tinkerbella nana is a newly discovered species of fairyfly from Costa Rica. Fairyflies are a type of chalcid wasp, and almost all are parasites, living on the eggs and larvae of other insects. It's a gruesome way to live, but it makes fairyflies useful for farmers, who sometimes import them to control nasty pests.

Many fairyflies are extraordinarily tiny, including Kikiki huna, a Hawaiian species that grows to be only 0.005 inches (0.13 millimeters) long ? about the diameter of the tip of a fine drawing pen. This makes them tough to find, but researchers led by John Huber of Natural Resources Canada conducted their search by seeking out insect eggs in leaf litter, soil and on plants in the Costa Rican province of Alajeula.

There, they found specimens of T. nana, none of which were more than 250 micrometers in length. One micrometer is a thousandth of a millimeter.

Under the microscope, these teeny-tiny insects reveal fine detail, particularly their long, skinny wings, which terminate in hairlike fringe. This wing shape may help ultra-small insects reduce turbulence and drag when they fly, a feat that requires beating their wings hundreds of times per second.

Researchers don't know how small insects can get, Huber said.

"If we have not already found them, we must surely be close to discovering the smallest insects," he said in a statement. The researchers published their discovery today (April 24) in the Journal of Hymenoptera Research.

(Credit: Courtesy Celeste & Sydney Recovery Fund)

Sydney Corcoran, who was injured during the Boston Marathon bombing on April 15, was still recovering at Boston Medical Center on Tuesday for her 18th birthday.

So fellow bombing?victim?Jeff Bauman stopped by to give her a present.

Bauman is the man in the wheel chair?pictured?in the now famous Associated Press photo taken shortly after the bombing.

Bauman, 27, lost both legs in the attack, and Corcoran is recovering from a severed femoral artery in a hospital.

Corcoran, a Lowell High School senior, was at the marathon with her parents when the bomb exploded. Her mother?s legs were badly damaged in the blast and had to be amputated below the knee, her cousin Alyssa Carter told ABCNews.com. Corcoran?s artery wound would have been fatal if strangers didn?t rush to stop the bleeding.

Taiwan man contracts H7N9 bird flu, first outside mainland China

TAIPEI (Reuters) - A 53-year-old Taiwan businessman has contracted the H7N9 strain of bird flu while travelling in China, Taiwan's Health Department said on Wednesday, the first reported case outside of mainland China.

The man was hospitalized after becoming ill three days after returning from Suzhou on April 9, Health Department Minister Wen-Ta Chiu told a news conference. Chiu said the patient was diagnosed with the H7N9 virus and was in serious condition.

Chiu said Taiwan will take appropriate measures, including opening a special out-patient clinic for H7N9 cases.

Taiwan and China have growing business and economic ties, and many businessmen frequently travel across the straits.

As of Tuesday, 108 people had contracted the disease on the mainland since the first deaths were reported last month.

California Wants Labels Warning of BPA in Foods - Shape

The state of California recently admitted what many consumers and health and nutrition experts have been speculating for years: Canned food chemical bisphenol A (BPA) is toxic and may cause health problems. After officially adding the chemical to its Prop 65 list?a list of substances that are known carcinogens or endocrine-disruptors?the state will now require warning labels to be posted on products that contain high levels of BPA sold in California.

"This decision is a step in the right direction," says SHAPE Diet Doctor Mike Roussell, Ph.D., author of The Six Pillars of Nutrition. "I think this is good validation that these endocrine-disrupting chemicals have real effects on our bodies. I hope this will be the first of several similar decisions."

What is bisphenol A?
BPA is what's known as an "everywhere chemical" because it shows up in seemingly innocent items you use every day, such as canned foods, plastic water bottles, pacifiers, and teethers. BPA also used to be present in baby food containers, but a few years ago the Food and Drug Administration (FDA) banned it?not because it deemed it harmful but because of widespread public outcry.

There is some disagreement within the healthy living community about how just how bad BPA is for you, but the chemical has been linked to a wide variety of health effects including behavioral changes, altered brain behavior, cancer, and cardiovascular disease.

RELATED: The U.S. allows more questionable ingredients in its food products than other countries. Read up on nine foods that contain toxic ingredients?and what to eat instead.

"BPA is what's referred to as an endocrine disruptor, meaning that once in the body, it mimics estrogen and can block testosterone," says registered dietitian Julie Upton. "When something mimics estrogen or has an estrogenic effect, it can increase your risk of certain types of cancers that are estrogen-dependent, such as breast cancer or ovarian cancer. BPA can also increase your risk of prostate cancer."

What does this mean for consumers?
California's Prop 65 is a "right to know" law that was approved by California voters in 1986 and requires the state to maintain a list of chemicals that cause cancer or reproductive toxicity. It also includes asbestos, lead, mercury, and benzene. However, because the proposed "safe harbor level" or the maximum allowable dose for BPA is set so high at 290 micrograms per day, it's possible most BPA-containing products sold in California won't actually have to carry a label, Sarah Janssen, a senior scientist for the Natural Resources Defense Council, wrote on her blog.

"That is a relatively high level of exposure and is based on high-dose studies from a 2008 National Toxicology Program report. This is not likely to result in any warning labels on products in California, but it can be changed, and we think it should be, based on newer science, which continues to find evidence of harm at much lower levels of exposure."

How can you minimize your exposure to BPA?
BPA leaches into the food and water supply, making it hard to avoid. In fact, the Centers for Disease Control and Prevention has found BPA in the urine of 93 percent of the people it's tested and, according to Roussell, it's ubiquitous in fetal blood tests as well. However there are a few ways to minimize your exposure to it:

1. Eat less processed food. Both Roussell and Upton agree that by eating fewer foods that come in cans or packages, you can reduce your exposure significantly.

2. Lose a few pounds. "Fat cells are estrogenic, so one way to minimize the potential for estrogen-driven problems is to keep body fat in check," Upton says. "This doesn't deal with BPA directly but will reduce your estrogen exposure."

3. Go BPA-Free.?More and more companies are starting to phase BPA out of their products. If you purchase a lot of canned foods, look for brands that are labeled "BPA-free," such as Eden Organics. If you find yourself reusing plastic water bottles a lot, try to look for brands with a number 2, 4, or 5 on them, but avoid any with the number 7?this is an indication that the bottle is manufactured with polycarbonate and contains BPA.

RELATED: Watch out for these seven ingredients robbing you of nutrients and start giving your body the vitamins and minerals it needs.

UPDATE: As of April 19, a California judge has granted a preliminary injunction in the American Chemistry Council's (ACC) case against the Office of Environmental Health Hazard Assessment's decision to add BPA to the Prop 65 list, effectively removing BPA from the list after all, at least until a decision is made.

"We do not believe there is a scientific basis for including BPA on the Proposition 65 list and we look forward to our case being heard on the merits sometime this summer," Steve Hentges, executive director of ACC's polycarbonate and BPA global group said after the injunction was issued.

The suit from the ACC maintains that California EPA officials made the decision to put BPA on Prop 65 by "circumventing the state's scientific process by allowing administrative staff to override the decision of a scientific panel from 2009." The judge agreed with the plaintiff, hence the injunction.

Alien-looking termite gut denizens at the SF Exploratorium!

Seldom do protists show up in public places (as man-made creations; plenty of them thrive happily unseen), especially those who reside where the sun don?t shine: the hindgut of wood-eating termites and cockroaches. There, they perform a function glorious for the termite or roach, but often annoying (or devastating) to us ? they digest cellulose from wood. Furthermore, they sustain a thriving ecosystem of various symbiotic bacteria, and loitering protists of uncertain employment (as in, we hardly know what they eat or do). Besides being ecologically and practically interesting, these gut denizens also exhibit some stunningly elaborate morphologies: for example these parabasalid specimens here. Oh, and many of them lack conventional mitochondria, instead relying on reduced and modified forms such as hydrogen-producing hydrogenosomes (which get quickly surrounded by hydrogen-hungry methane-producing archaeans). In short, the termite and roach gut communities are awesome.

Luckily, a sampling of the alien world has been recently unveiled as a permanent exhibit at the San Francisco Exploratorium. Kevin Carpenter, a former member of the Keeling Lab (responsible for quite a bit of termite gut research), is notable for being exceptionally skilled with Scanning Electron Microscopy of protists. You can find some images from the exhibit on his site. It appears that the Exploratorium seems to have a live exhibit of termites and their denizens. So if you happen to be in the Bay Area, be aware that there is now a place to pay homage to some of the few eukaryotes who can digest hardly-edible cellulose.

Here?s a shrunken sample of the documented alien world ? a Saccinobacculus (?snake-in-a-bag?) with a bacteria-laden butt of Barbulonympha in the background. Click on? either of them for a further journey in the termite (and roach) gut!

The MSCI's broadest index of?Asia-Pacific?shares outside?Japan?was down 0.3 percent, with Australian shares falling 0.4 percent, hit by sinking copper prices which deepened concerns about demand for?Australia's raw materials.

South Korean shares opened down 0.4 percent.

"Cyclical large-caps are losing steam as the rate of economic recovery appears slowing in major countries such as the U.S. and?China, while first-quarter earnings forecasts continue to be revised down," said?Chang Jae-ho, an analyst at Daishin Securities.

Apple Inc fell below $400 a share for the first time since late 2011 after a poor revenue forecast from key supplier?Cirrus Logic?while shares of Intel Corp, the world's largest?semiconductor?maker, initially fell after it forecast a sharp decline in its current-quarter revenue and trimmed its 2013 capital spending plans.

European shares fell to a 2013 low.

Japan's Nikkei average opened down 0.8 percent.

Commodities also fell on Wednesday, with copper, seen as a gauge for manufacturing and?China-related growth, shedding over 3 percent. A 10.3 percent decline in European car sales over March weighed on copper prices as an indicator of slumping demand for metals.

Oil prices tumbled for a sixth straight session on Wednesday, with Brent crude futures falling below $98 per barrel for the first time since July as rising U.S. fuel supplies added to overall concern about global oil demand.

(AP) ? Angel Cabrera usually comes up big in these situations.

He did again.

It just wasn't enough to win his second green jacket.

Cabrera forced a playoff with a brilliant 7-iron to 3 feet on the 72nd hole of the Masters, but he lost to Adam Scott on the second hole of a playoff when the Australian rolled in a 12-foot putt.

Cabrera just missed a chip-in from off the front of the green at the first extra hole ? letting out an "Ohhhhh!" as it slid by the edge ? and his 15-footer on the second playoff hole stopped right next to the cup. He flipped his putter in the air and caught it, then tapped in for par.

At that point, all he could do was watch as Scott made his birdie to become the first Aussie to win the Masters.

The 43-year-old Cabrera missed a chance at becoming the second-oldest Masters winner, behind only Jack Nicklaus in 1986.

Still, it was a remarkable accomplishment for a golfer who came in ranked No. 269 in the world, and never seems to play winning golf unless he's in the biggest tournaments of all.

"I like the challenges," Cabrera said through an interpreter. "These tournaments are very, very important for me. So sometimes they bring my best out of me."

Indeed, they do.

Before this Masters, his last win on the PGA or Europeans tours came at the 2009 Masters, where he defeated Chad Campbell and Kenny Perry in a playoff. And before that was The 2007 U.S. Open at Oakmont, where Cabrera outdueled Jim Furyk down the stretch.

The big guy almost did it again ? with his son on the bag, no less ? which would have put him a pretty exclusive club as a three-time major champion.

"The only thing in my head," Cabrera said, "was winning."

Playing in the final group with Brandt Snedeker, Cabrera was by far the most solid player among the leaders as a steadily increasing rain didn't bother a player nicknamed "El Pato" ? The Duck. He cruised through the front side with two birdies and seven pars, making the turn with a two-stroke lead.

But an errant drive into the pine trees at No. 10 was the first big miscue, leading to a bogey. The shot he would really like to have back came at the par-5 13th, where he drove into the pine straw on top of the hill but still decided to go for the green, 203 yards away.

Cabrera chunked it a bit and watched his ball settle in Rae's Creek. He wound up with another bogey and surrendered the lead to Jason Day.

In hindsight, Cabrera still thinks it was a good decision.

"I had a very good angle, and I had a very good lie," he said. "And I was thinking about making a birdie. I told my son that, you know, we could do an eagle, also."

Another wild shot at the par-5 15th, a hole that gave up birdies to nearly all the contenders, left Cabrera to settle for par. At that point, it looked like he was done, facing a two-shot deficit as he headed to No. 16.

But this duck wasn't going to away that easy.

Cabrera hit a brilliant tee shot over the water at the par-3 hole and sank a 15-footer for birdie to close the gap. Turns out, it was Day who faded away, making bogeys at 16 and 17. But that other Aussie took control, and Cabrera could only watch from the middle of the 18th fairway as Scott celebrated up on the green, having claimed the lead with a 20-footer for birdie.

While Scott went off to sign his scorecard, Cabrera knew what he had to do ? hit an even better shot.

Boy, did he ever.

From 163 yards away, Cabrera sent his ball soaring toward the green. It rolled to a stop 3 feet from the cup. When Cabrera made the gimme of a putt, he hugged Angel Jr. and headed to the playoff.

Cabrera nearly won it on the first extra hole, a repeat of No. 18. Chipping over Scott's ball, which also had rolled off the front of the green, Cabrera flipped a shot that landed right where he wanted and looked like it was going in. He settled for par, as did Scott, and the two headed off to No. 10.

In the fading light, especially around the green shaded by towering pine trees, Cabrera putted first and just missed. Scott did not. Game over.

"That's golf," Cabrera said. "Golf gives and takes. Sometimes you make those putts, sometimes you just miss them. "

As Scott celebrated, Cabrera walked up with his right hand outstretched. Despite the language barrier, the two have become good friends, from their time as teammates in the Presidents Cup to frequent encounters out on the various world tours. They walked off the green arm in arm, both patting each other on the back. As Cabrera started to pull away, Scott yanked him close and said a few words.

No interpreter was needed.

"Angel is a great man," Scott said. "He's a gentleman."

The winner was especially touched by Cabrera's gesture in the middle of the 10th fairway, before they headed down toward the final green of a long day. After watching Scott's ball roll to a stop, Cabrera gave him a thumbs-up.

"For him to do that at that point," Scott said, "was very nice."

Cabrera didn't look at this as an opportunity missed. Chances are, you won't hear much out of him, at least in the United States, for the next few months,

But when the U.S. Open rolls around in June, he might just be one of the guys in the mix.

That's a pretty big tournament, after all.

"I have a lot of confidence in myself," Cabrera said. "I'm going to keep on going."

GM, Ford agree to jointly develop fuel-saving transmissions

DETROIT (Reuters) - General Motors Co and Ford Motor Co , the two largest U.S. automakers, have agreed to jointly develop a new line of nine- and ten-speed automatic transmissions to boost the fuel economy and performance of their lineup, the companies said on Monday.

The pact marks the third time in the last decade that the two automakers have collaborated on transmissions. The joint effort allows GM and Ford to bring the transmissions to market more quickly and at a lower cost than if they worked alone.

GM and Ford will build both front- and rear-wheel drive transmissions as part of this effort. Engineering teams for both companies have already started initial design work.

The U.S. auto industry is scrambling to find ways to boost fuel economy by 2025, when U.S. government standards mandate that automakers show a corporate average fuel economy (CAFE) of 54.5 miles per gallon (23.2 km per liter).

That translates to about 39 mpg in real world driving, or nearly two thirds higher than the average fuel economy for the 2012 model year vehicles. The Environmental Protection Agency projects that, on average, 2012 vehicles got around 23.8 mpg.

Fish prone to melanoma get DNA decoded

Apr. 15, 2013 ? Scientists at Washington University School of Medicine in St. Louis and elsewhere have decoded the genome of the platyfish, a cousin of the guppy and a popular choice for home aquariums.

Among scientists, the fish are meticulously studied for their tendency to develop melanoma and for other attributes more common to mammals, like courting prospective mates and giving birth to live young.

Known scientifically as Xiphophorus maculatus, platyfish sport a variety of spectacular colors -- brilliant oranges, yellows and a lovely iridescent silver -- and myriad striped and speckled patterns. And when melanomas develop, they are easy to spot, even to an untrained eye.

"In platyfish, melanomas typically develop as black splotches along the tail and fins," says senior author Wesley Warren, PhD, a geneticist at Washington University's Genome Institute. "These fish are an ideal model for exploring the many unknowns of cancer, including how, when and where it develops in the body as well as its severity."

Scientists at Washington University, the University of W?rzburg in Germany and Texas State University led an international team involved in sequencing and analyzing the platyfish genome. Their findings are available online in Nature Genetics.

"Now that we have the genome in hand, we can tease apart the way genes interact with one another to cause melanoma," says co-lead author Manfred Schartl, PhD, of the University of W?rzburg in Germany. "Just as in human melanoma, genes that play a role in pigment cells also influence the development of melanoma in platyfish."

The platyfish genome includes some 20,000 genes, roughly the same number found in the human genome. But unlike humans and other mammals, the chromosomes of the platyfish, like those in other fish, have remained remarkably intact over some 200 million years of evolution.

"It's very much a mystery as to why these chromosomes are so structurally similar among fish species over long time periods of evolution because they live in vastly different aquatic environments," says Warren.

The platyfish is a prolific breeder. But while most fish lay eggs, platyfish females give birth to live young, often in broods of more than 100.

Comparing the genes of platyfish to those in mice and other mammals that give birth to their young, the scientists found a number of altered genes in the fish involved in live-bearing birth.

"Surprisingly, we found that the platyfish retain some yolk-related genes typically found in fish that lay eggs to produce their offspring, and genes involved in placenta function and egg fertilization displayed unique molecular changes," says co-lead author Ron Walter, PhD, of Texas State University.

While humans are known for their higher-level thinking and behaviors, platyfish and other fish have evolved their own set of complex behaviors, like courting, schooling and avoiding predators that far exceed the abilities of amphibians, reptiles and other lower vertebrates. Looking through the platyfish genome, the researchers found a number of gene copies linked to cognition in humans and other mammals that could underlie these behaviors.

"These gene copies were retained at a high rate in the platyfish, which give them a chance to evolve different functions," Warren explains. "In this case, we believe the extra gene copies gave platyfish and other related fish the ability to develop more complex behaviors, which is unexpected for many lower-level vertebrates."
