Higgs may spell doom, unless supersymmetry saves us

Is the Higgs boson a herald of the apocalypse? That's the suggestion behind a theory, developed more than 30 years ago, that is back in the headlines this week. According to physicists, the mass of the Higgs-like particle announced last summer supports the notion that our universe is teetering on the edge of stability, like a pencil balanced on its point.

"It may be that the universe we live in is inherently unstable," Joseph Lykken, of the Fermi National Accelerator Laboratory in Batavia, Illinois, said on Monday at a meeting of the American Association for the Advancement of Science. "At some point, billions of years from now, it's all going to be wiped out."

Physicists have been wringing their hands about this scenario since 1982, when theorists Michael Turner and Frank Wilczek published a paper about it in Nature, NBC News points out. The pair showed that the vacuum of space can be in different energy states, and it will be most stable at its lowest energy. Trouble arises if we're not there yet, and we're inhabiting a temporarily stable state that should ultimately collapse.

"The universe wants to be in a different state, so eventually to realize that, a little bubble of what you might think of as an alternate universe will appear somewhere, and it will spread out and destroy us," Lykken said at AAAS.

Enter the Higgs boson, the particle form of the field that gives mass to several fundamental particles. The Higgs field permeates the vacuum of space, which means the mass of the boson and the stability of the vacuum are closely intertwined. Theory predicted that if the Higgs boson is heavier than about 129 gigaelectronvolts (GeV), the universe should be on safe footing.

But in July 2012 physicists at CERN, near Geneva, Switzerland announced that a particle closely matching the Higgs had been found by experiments in the Large Hadron Collider (LHC). The much celebrated particle has a mass of about 126 GeV - light enough to raise fears of instability.

There is still hope for the universe as we know it. Some theorists pointed out that the relationship between the Higgs mass and the vacuum of space depends on the mass of a particle called the top quark. If the top quark's mass is different than we think it is, stability might reign.

There are also anomalies with the Higgs measurement, like the fact that it decays into photons more often than predicted. That hints we may yet find particles from the theory of supersymmetry, which says each ordinary particle has heavier "superpartners". If the Higgs has such a relative, it might save us from destruction. But some of these predicted particles, particularly the superpartners of the top quark, can push the universe back into instability.

The worries may remain unconfirmed for a while. The LHC is shutting down for a two-year break so engineers can prepare the machine to shoot higher-energy particle beams, which are needed to probe for superpartners.

Sony bills coming PS4 console as future of gaming

NEW YORK: Sony unveiled a new-generation PlayStation 4 (PS4) system on Wednesday and laid out its vision for the "future of gaming" in a world rich with mobile gadgets and play streamed from the Internet cloud.

At a press event in New York, computer entertainment unit chief Andrew House said PS4 "represents a significant shift from thinking of PlayStation as a box or console to thinking of the PlayStation 4 as a leading place for play."

PS4 was designed to get to know players, ideally to the point of being able to predict which games people will buy and have them pre-loaded and ready to go.

It also allows live streaming of gameplay in real-time, letting friends virtually peer over one another's shoulders and even letting game makers to act as "directors" guiding players along.

Sony has also given a "green light" to building "the most powerful network for gaming in the world", according to David Perry, chief of Gaikai cloud gaming company purchased last year by Sony.

Gaikai specialises in letting people play video games streamed from the Internet "cloud" instead of buying titles on disks popped into consoles or computers.

"By combining PlayStation 4, PlayStation Network and social platforms, our vision is to create the first social network with meaning dedicated to games," Perry said during the event.

A button on the PS4 controller will let players instantly stream in-game action to friends in real time, and even allow someone to transfer control to more capable allies when stuck, according to Perry.

He expressed a vision of letting people access and play video games old or new on the Internet using PS4, smartphones, tablets or PS Vita handheld devices.

"We are exploring opportunity enabled by cloud technology with a long-term vision of making PlayStation technology available on any device," Perry said.

"This would fundamentally change the concept of game longevity, making any game new or old available to get up and running on any device, anywhere."

Sony needs to adapt to changing lifestyles while not alienating video game lovers devoted to its hardware.

Low-cost or free games on smartphones or tablet computers are increasing the pressure on video game companies to deliver experiences worth players' time and money.

With the press event still in progress, Sony had yet to indicate availability or pricing for the PS4. New-generation consoles are typically priced in the $400 to $500 range, and blockbuster game titles hit the market at $60 each.

Woman's corpse found in LA hotel's water tank

By Alan Duke, CNN

updated 8:51 PM EST, Wed February 20, 2013

STORY HIGHLIGHTS

• Elisa Lam disappeared from the hotel on January 31


• Canadian's body was found in a Cecil Hotel water tank Tuesday


• Police investigating death

Los Angeles (CNN) -- Tourists staying at a Los Angeles hotel bathed, brushed teeth and drank with water from a tank in which a young woman's body was likely decomposing for more than two weeks, police said.

Elisa Lam's corpse was found in the Cecil Hotel's rooftop water tank by a maintenance worker who was trying to figure out why the water pressure was low Tuesday.

Lam's parents reported her missing in early February. The last sighting of her was in the hotel on January 31, Los Angeles Police said.

Detectives are now investigating the 21-year-old Canadian's suspicious death, police Sgt. Rudy Lopez said.

It was not clear whether the water presented any health risks. Results on tests on the water done Wednesday by the Los Angeles Public Health Department were expected later in the day.

The hotel management has not responded to CNN requests for comment.

Video appears to show four cisterns on the hotel roof.

People who stayed at the Cecil since Lam's disappearance expressed shock about developments.

"The water did have a funny taste," Sabrina Baugh told CNN on Wednesday. She and her husband used the water for eight days.

"We never thought anything of it," the British woman said. "We thought it was just the way it was here."

What she described was not normal.

"The shower was awful," she said. "When you turned the tap on, the water was coming black first for two seconds and then it was going back to normal."

The hotel remained open after the discovery, but guests checking in Tuesday were told not to drink it, according to Qui Nguyen, who decided to find a new hotel Wednesday.

Nguyen said he learned about the body from a CNN reporter, not the hotel staff.

Library of Congress works to save priceless recordings

(CBS News) CULPEPER, Va. -- Cameras and microphones are virtually everywhere these days, and it seems just about everything that happens is preserved forever on the internet.

Of course, it wasn't always that way. The Library of Congress has just reported that 80 percent of motion pictures filmed before 1930 -- and countless audio recordings from that era -- are gone. But the library has a plan to stop this bleeding of priceless history.

A 1936 Louis Armstrong recording is an artifact nearly lost to time. It's a nickel-plated disc widely used to record sound in the first half of the 20th century.

"It's the equivalent to an original camera negative for a motion picture," says Patrick Loughney, who is leading the effort to save these cultural relics for the Library of Congress.

"What goes on here is the archaeology of American popular audio-visual history," Loughney says.

When you think of the Library of Congress, you think of old documents and typewriter-smudged papers. Not here.

"It's quite remarkable that the library, very early on, got into the acquisition of sound recordings and then radio programs," Loughney says. "They were considered a cultural record."

Cylinders invented by Thomas Edison in the 1800s were recently donated by a private collector. They are the first known devices to record sound.

"It was literally beeswax, so it could melt if you heated it up too high or dropped it would break," says Loughney.

One recording, now digitally restored, is an 1896 campaign song for William McKinley.

Watch: Library of Congress sports interviews go beyond wins and losses, below.

The library has 90 miles of shelves at its 45-acre conservation campus in Culpeper, Va. Here, specialists are preserving more than a million motion pictures, including an 1894 film called "Annabel Butterfly." It's one of the oldest known films ever restored -- each frame was originally colored by hand.

Technicians have digitized thousands of TV shows, including the only appearance of The Doors on "The Ed Sullivan Show." They've even restored color to a 1975 blues documentary.

"There is a growing amnesia about America past," Loughney says. "Our job is to try and bolster that American memory, try to save it for future generations who might find value in what we're preserving."

Newtown Shooter Had Sensory Processing Disorder

From the time he was little, Adam Lanza couldn't bear to be touched. By middle school, the chaos and noise of large, bustling classrooms began to upset him. At 20, just before the Newtown shootings, he was isolated and, the world would later learn, disturbed.

All this was revealed in "Raising Adam Lanza," an investigative report by the Hartford Courant in partnership with the PBS news program FRONTLINE, which aired Tuesday night.

Before the age of 6, Lanza had been diagnosed with a controversial condition, "sensory integration disorder" -- now known as sensory processing disorder, according to the report.

Those with sensory processing disorder or SPD may over-respond to stimuli and find clothing, physical contact, light, sound or food unbearable. They may also under-respond and feel little or no reaction to pain or extreme hot and cold. A third form involves sensory motor problems that can cause weakness and clumsiness or delay in developing motor skills.

Whether SPD is a distinct disorder or a collection of symptoms pointing to other neurological deficits, most often anxiety or attention-deficit hyperactivity disorder (ADHD), has been debated by the medical community for more than two decades.

No one will know why the withdrawn Lanza shot his mother four times in her own bed, then went to Sandy Hook Elementary School to slaughter six women and 20 first-graders before taking his own life on Dec. 14, 2012.

But this report, the most detailed account to date on his troubled life, paints a picture of a child coping with special needs and a mother, "devoted but perhaps misguided," struggling unsuccessfully to help.

"The most surprising thing for me was this sort of inwardness of Adam, a world view of someone that was afraid of the world," said show producer Frank Koughan. "He just reacted badly to the whole world and didn't want to be part of it. He was not some violent monster, except on one particular day, when he was exceedingly monstrous."

The investigative team interviewed family and friends of the shooter's parents, Nancy and Peter Lanza, and reviewed a decade's worth of messages and emails from his mother to close friends, describing her son's socially awkward behavior.

"Adam was a quiet kid. He never said a word," Marvin LaFontaine, a friend of Nancy Lanza, told them. "There was a weirdness about him and Nancy warned me once at one of the Scout meetings … 'Don't touch Adam.' She said he just can't stand that. He'd become teary-eyed and I think he would run to his mother."

In 1998, the Lanzas left their home in New Hampshire for Connecticut with Adam, who had already been diagnosed with the sensory disorder and was "coded" with an individual education plan, according to a family member who did not want to be identified by FRONTLINE.

"It was somebody well-placed who was completely in a position to know," said Koughan, 45, a veteran journalist who produced the film, "Drop-Out Nation."

Lanza didn't recognize pain, another feature of some types of SPD. He couldn't cope with loud noise, confusion or change, which would cause him to "shut down," according to the report.

"He'd almost go into a catatonic kind of state, which is another reason why in hindsight, he didn't seem like a threat to anybody," said Koughan. "He didn't lash out or beat up kids. He went within himself, until one day he didn't."

Retinal implants clear new hurdle

PARIS: German-designed implants aimed at restoring vision to patients blinded by retinal disease have succeeded in the second phase of trials, researchers reported on Wednesday.

The device was tested for up to nine months among nine people with retinitis pigmentosa, an inherited disease in which light receptors on the back of the eyeball degenerate and eventually cease to function.

"Of the nine patients observed in the study, three patients were able to read letters spontaneously," Retina Implant AG, a nine-year-old technology startup company that invented the device, said in a press release.

"During observation in and outside the laboratory, patients also reported the ability to recognise faces, distinguish objects such as telephones and read signs on doors."

The study appears in Proceedings of the Royal Society B, a journal published by Britain's de-facto academy of sciences.

The device consists of a tiny light-sensitive chip measuring 3mm by 3mm (0.11 x 0.11 inches), which sends electrical signals down the optic nerve to the brain, providing a "diamond-shaped" black-and-white image with a field of 15 degrees.

Attached to the retina, the implant is powered via a thin cable which connects to a small coil fitted under a fold of skin behind the ear.

The coil is charged when a handheld battery unit is brought up close to it -- the same principle of wireless charging that is used, for instance, in electrical toothbrushes -- and thus means it can be used outdoors.

The battery unit also has two knobs, enabling the user to adjust the brightness and contrast of the image.

The patients received the implant in one eye, the one with the worst visual function.

One of the nine had to drop out of the experiment after the optic nerve was damaged during the implant operation, and another experienced a buildup in eyeball pressure which was successfully treated with drugs.

New drugs and revolutionary medical devices typically undergo a three-phase process of trials on human volunteers.

The number of patients and the scope of the test gradually widens, in a bid to ensure that the innovation is both safe and effective.

The first trial of the implant, published in 2010, used a cable, rather than wireless technology, to power the device.

There are several other entrants in the field for retinal implants, reflecting big advances in electronic miniaturisation and microsurgery in the past decade.

None claims to be a cure but rather an aid to distinguish between light and darkness and ascertain the shape of objects.

"Although the restoration of vision described here is limited, blind persons with no alternative therapy options regard this type of artificial vision as an improvement in everyday life," the German doctors said.

Last week the US firm Second Sight Medical Products gained US regulatory approval in addition to the green light from Europe for its Argus II retinal prosthesis.

There is also a 24-electrode device made by Bionic Vision Australia, which has so far been tested on one patient.

Georgia inmate granted last-minute stay of execution

From Tom Watkins and Matt Smith, CNN

updated 8:22 PM EST, Tue February 19, 2013

Warren Lee Hill's defenders say he should not be executed because he is mentally impaired.

STORY HIGHLIGHTS

• The 11th U.S. Circuit Court of Appeals and the Georgia Court of Appeals grant the stays


• Warren Lee Hill's attorney says they came within a half hour of the scheduled execution


• Hill's defenders say he's mentally disabled


• Hill was convicted of beating to death another Georgia inmate in 1990

Atlanta (CNN) -- Twice-convicted killer Warren Lee Hill was granted final-hour stays of execution on Tuesday, his attorney said.

The stays came from the 11th U.S. Circuit Court of Appeals and the Georgia Court of Appeals.

"I think we were within about a half hour of the execution," said Brian Kammer, an attorney for Hill, whose supporters say is mentally disabled.

The Georgia Court of Appeals acted on a appeal of a challenge to the way the prison handles the lethal injection drugs used in executions, while the federal appeals court issued a stay "ordering a further briefing on the issue of mental retardation," Kammer said.

Earlier Tuesday, the U.S. Supreme Court denied a stay of execution, as did the state Supreme Court, while the Georgia State Board of Pardons and Paroles similarly denied a request for clemency.

The execution had been scheduled for 7 p.m. ET at a state prison in Jackson, about 45 miles south of Atlanta.

Hill was sentenced to death for the 1990 killing of Joseph Handspike, another inmate in a Georgia state prison.

He was convicted of beating Handspike to death with a nail-studded board while serving a life sentence in the 1985 killing of his girlfriend, Myra Wright.

His lawyers have argued that Hill's IQ of 70 means he should be spared under a 2002 decision that barred the execution of the mentally disabled. But a string of state courts has said Hill doesn't qualify under Georgia law, which requires inmates to prove mental impairment "beyond a reasonable doubt."

"This is the strictest standard in any jurisdiction in the nation. Even Warren Hill, a man with an IQ of 70 who is diagnosed as mentally retarded by every doctor who has examined him, found it impossible to meet this standard of proof," Kammer said.

Handspike's family has called for the execution to be called off. The Georgia Council on Developmental Disabilities also weighed in against the execution, stating, "No other state risks the lives of those with developmental disabilities to this extreme."

Three doctors who examined Hill for the state "have now revised their opinions and find that Mr. Hill does meet the criteria for mental retardation," his lawyers argued in court papers.

But lawyers for the state have said that Hill served in the Navy, held a job and managed his money before Wright's killing -- signs that he didn't necessarily meet the legal standard for retardation, even though he has a low IQ.

Hill had previously been scheduled for execution in July, but the state Supreme Court halted the execution on procedural grounds.

Georgia has executed 52 men since the U.S. Supreme Court reinstated the death penalty in 1973, according to the Georgia Department of Corrections. There are currently 94 men and one woman under death sentence in the state.

Multiple injuries in Kansas City gas fire

Updated 8:53 PM ET

KANSAS CITY, Mo. A car crashed into a gas main Tuesday evening in an upscale Kansas City shopping district, sparking a massive blaze that engulfed an entire block and caused multiple injuries, police said.

Seven or eight people were injured and taken to area hospitals, police Sgt. Tony Sanders said Tuesday, who added that there were no reports of fatalities. Sanders said the manager of JJ's restaurant, which was destroyed in the blaze, was unable to account for three people, but it was unclear whether they were caught in the blaze or had left earlier.

Earlier police spokeswoman Rhonda Flores said it appeared that a car crashed into a gas main near JJ's just after 6 p.m. Flores said an initial call for three ambulances had been increased to 10. She said she had not heard of any reported fatalities. Flores said the car crash appeared to have been accidental.

CBS affiliate KCTV Kansas City reported of witnesses seeing people running out of the restaurant covered in blood.

The University of Kansas Hospital is treating two people who brought themselves to the facility, said spokesman Bob Hallinan. He said the two injured people were being evaluated, and he didn't immediately have their conditions.

Kerry O'Connor, a spokeswoman for St. Luke's Hospital, which is near the scene of the fire, said several patients were on the way to the hospital. She said they haven't been assessed yet but "they appear to be critical at this time."

Fire officials didn't immediately return a phone call seeking comment Tuesday evening.

The smell of gas was very strong near the area long after the suspected explosion.

There were signs that utility work was being done in area. A phone message left Tuesday seeking comment from Missouri Gas Energy was not immediately returned.

Video showed dozens of firefighters and other emergency responders battling a massive blaze that appeared to have engulfed an entire block, with flames burning through the roofs. Black smoke swirled in the air and debris littered surrounding streets.

The shopping area was established in 1922 by J.C. Nichols. Based on the architecture of Seville, Spain, it includes retail, restaurants, apartments and offices.

Arias Says Violent Sex Preceded Killing

Jodi Arias and her ex-boyfriend, Travis Alexander,, had increasingly violent sex in which he tied her to his bed, twisted her arm, bent her over a desk for anal sex, and made sex videos with her in the hours leading up to the stabbing and shooting frenzy that left Alexander dead.

It was a day in which Arias, 32, inched closer to telling the court how the killing of Alexander took place, but after several hours of increasingly emotional testimony the court was adjourned until Wednesday.

In her sixth day on the stand, Arias tearfully described the sex-filled hours that led to Alexander's death on June 4, 2008. She is charged with murder for killing her former boyfriend, but claims she was forced to kill him self-defense. She could face the death penalty if convicted.

"He tied me up, (on) the bed. It's not my favorite but it's not unbearable," Arias told the court.

She said he used a kitchen knife in the bathroom to cut the rope to the proper length, but she didn't remember whether he left the knife in the bathroom or brought it back to the nightstand in the bedroom.

"There are a lot gaps that day... a lot of things I don't remember that day," she said.

Arias and Alexander then took graphic sexual photos of one another and made a sex video, both of which Arias said were Alexander's ideas. Arias has girlish braids in the pictures.

But the mood of the afternoon turned, she said, when Alexander became angry over a scratched computer disk of photos she gave him. He threw the CD and Arias said she became "apprehensive" of his rising temper.

"I know he's getting angry because Napoleon [Alexander's dog] got up and left the room and he always leaves the room when he gets mad." she testified.

"I don't know that I was consciously thinking (of violence) but I was more tense. I stood up, went to walk over to him, to rub his back and make sure he was okay," she said. "But he grabbed me on the upper arms, spun me around and grabbed my right arm and twisted it behind my back, and bent me over the desk, and pressed up against me."

"I was scared he was going to throw me or something, kick me," she continued. "He pressed his groin up against my butt, did a few thrusts and then started pulling my pants down."

The pair then had anal sex, which Arias said pacified Alexander.

"I was very relieved. I felt like we had avoided catastrophe. It could have led to another fight," she said.

Instead of a fight, Alexander, who was 27 and a devout Mormon, and Arias decide to go upstairs and take more nude photos of one another. Arias said she hoped the photos would satisfy Alexander over his frustration with the scratched CD.

Evidence introduced earlier in the trial show that Alexander was killed while Arias was photographing Alexander in the shower.

Timeline of the Jodi Arias Trial

Earlier, Arias explained that she wasn't planning to visit Alexander during her roadtrip from her home in California, but was convinced by him to spontaneously take a detour to his house for sex and to hang out.

"The very last time I called Travis it was kind of like, I don't know how to describe it, he had been very sweet and was guilting me and making me feel bad that I was taking this big trip without going to see him," Arias said this afternoon.

"When I called him last time it was just like all right, I'm going," she said. "(Sex) was our thing at that time. I wasn't going to go there, stay the night and not do that."

Arias' attorney, Kirk Nurmi, asked her repeatedly on the stand if Arias brought a gun or knife with her on the roadtrip and to Alexander's house. She said that she did not.

She also denied a series of allegations made by the prosecution that she dyed her hair, rented an inconspicuous car, borrowed gas cans, turned off her cell phone, and switched money around her bank accounts as she left for Alexander's house because she was planning to murder him when she got there.

Arias said that her hair remained the same color, auburn-brown, throughout May and June, that she rented a car because her own car was not stable enough for highway travel, that she requested a white car instead of a red one because police pull red ones over more often, and that she transferred money to a business banking account for a tax write-off to classify it as a business trip.

The testimony about the road trip and Arias' planning could be key to the jury as they decide whether the killing was pre-meditated, as the prosecution claims. Arias could face the death penalty if convicted of murder with aggravating factors such as pre-meditation.

Arias said that she "didn't sleep at all last night" before testifying about the dramatic incident today. Her comment was stricken from the record.

Arias also described a barrage of threatening text messages sent by Alexander in which he told her he would exact "revenge" on her soon and called her a "sociopath."

She told the court that Alexander's temper would make her "cower."

The messages show a growing discord between the pair in April 2008, less than two months before Arias killed Alexander.

Biofuel rush is wiping out unique American grasslands

Say goodbye to the grass. The scramble for biofuels is rapidly killing off unique grasslands and pastures in the central US.

Christopher Wright and Michael Wimberly of South Dakota State University in Brookings analysed satellite images of five states in the western corn belt. They found that 530,000 hectares of grassland disappeared under blankets of maize and soya beans between 2006 and 2011. The rate was fastest in South Dakota and Iowa, with as much as 5 per cent of pasture becoming cropland each year.

The trend is being driven by rising demand for the crops, partly through incentives to use them as fuels instead of food.

The switch from meadows to crops is causing a crash in populations of ground-nesting birds. One of the US's most important breeding grounds for wildfowl, an area called the Prairie Pothole Region, is also at risk, with South Dakota's crop fields now within 100 metres of the wetlands. "Half of North American ducks breed here," says Wright.

Bill Henwood of the Temperate Grasslands Conservation Initiative in Vancouver, Canada, says the results are distressing. "Exchanging real environmental impacts for the dubious benefits of biofuels is counterproductive," he says. "Last year's record drought in the corn belt all but wiped out the crops anyway."
