Three is the magic number: A chain reaction required to prevent tumor formation
Protein p53 is known for controlling the life and death of a cell and has a key role in cancer research. P53 is known to be inactive in 50 percent of cancer patients. If researchers succeed in re-establishing the presence of p53 in patients, they may hold the key to a promising avenue of research. However, p53 does not act alone. -

Monkey Long Believed Extinct Found in Indonesia
Scientists working in the dense jungles of Indonesia have "rediscovered" a large, gray monkey so rare it was believed by many to be extinct.They were all the more baffled to find the Miller's Grizzled Langur -- its black face framed by a fluffy, Dracula-esque white collar -- in an area well outside its previously recorded home range.
The team set up camera traps in the Wehea Forest on the eastern tip of Borneo island in June, hoping to captures images of clouded leopards, orangutans and other wildlife known to congregate at several mineral salt licks.
The pictures that came back caught them all by surprise: groups of monkeys none had ever seen.
With virtually no photographs of the grizzled langurs in existence, it at first was a challenge to confirm their suspicions, said Brent Loken, a Ph.D. student at Simon Fraser University in Canada, and one of the lead researchers.
The only images out there were museum sketches.
"We were all pretty ecstatic, the fact that, wow, this monkey still lives, and also that it's in Wehea," said Loken.
The monkey, which has hooded eyes and a pinkish nose and lips, once roamed the northeastern part of Borneo, as well as the islands of Sumatra and Java and the Thai-Malay peninsula. But concerns were voiced several years ago that they may be extinct.
Forests where the monkeys once lived had been destroyed by fires, human encroachment and conversion of land for agriculture and mining and an extensive field survey in 2005 turned up empty.
"For me the discovery of this monkey is representative of so many species in Indonesia," Loken told The Associated Press by telephone.
"There are so many animals we know so little about and their home ranges are disappearing so quickly," he said. "It feels like a lot of these animals are going to quickly enter...

18:46It's a term used so rarely that most of us haven't heard of it. Even mental health professionals say they have read about it in textbooks rather than seen it up close.
But the mysterious symptoms of facial tics and verbal outbursts afflicting 12 teenage girls in the small community of LeRoy, N.Y., has brought new awareness to a very unfamiliar stress-related condition referred to as "conversion disorder."
Conversion disorder is characterized by problems with voluntary motor or sensory function that suggest a neurological or other general medical condition but aren't fully consistent with known biological causes or explanations, says David Fassler, a child and adolescent psychiatrist at the University of Vermont in Burlington. He says such outbreaks are more common in women and are associated with stress or anxiety. The girls began exhibiting symptoms last fall.
Neurologist Laszlo Mechtler of the Dent Neurologic Institute in Buffalo, who has treated all but one of the 12 girls, says tests have ruled out medical disorders, diseases and environmental factors. "These young ladies are individuals who come from a small community. One may have had a significant symptom, and it was like a wildfire."
When conversion disorder occurs in a larger group, it's called "mass psychogenic illness," Mechtler says.
A mass psychogenic illness affects groups of people in the same environment, such as a class at school or workers in an office who get similar physical symptoms at the same time.
That's why he says the publicity surrounding the case doesn't mean teenage girls around the USA will start exhibiting similar symptoms.
"You have to be in that environment. This is a unique situation, and it is unusual," he says, noting that in 25 years, he has never seen a group with these symptoms, but he has seen people diagnosed with conversion disorder.
Mechtler says that after getting permission from...

18:46A strong La Nina lowered the world's average temperature last year to its second-coolest reading of the 2000s, federal scientists announced Thursday.
The release of the two primary climate data sets -- from the National Climatic Data Center and NASA's Goddard Institute for Space Studies (GISS) -- both show the Earth as much warmer than average, but not as warm as recent years have been.
The climate center reported that the globe had its 11th-warmest year on record, while NASA marked the year as the ninth-warmest on record. For the most part, the two organizations use the same climate data sources but have slightly different methods of interpreting the data. Climate records go back to 1880.
La Nina is a natural, periodic cooling of tropical Pacific Ocean water that affects weather and climate around the world.
Since 2011 was the second-coolest year of the 2000s, does this mean global warming has slowed?
"There is no long-term cooling trend," said climate scientist Jake Crouch of the NCDC.
"If we look at the long-term trend of temperatures for the globe, we see an increasing trend," he said. "However, La Nina can temporarily suppress global temperatures."
In fact, 2011 was hotter than every year in the 20th century except 1998. "Global temperature in 2011 was lower than in 1998," NASA climate scientist James Hansen said in the GISS report. He said that nine of the 10 warmest years on record have occurred in the 21st century and that 2011 was cooled by a moderately strong La Nina.
"We conclude that the slowdown of warming is likely to prove illusory, with more rapid warming appearing over the next few years," Hansen said.
The climate data center calculated the globe's average temperature in 2011 was 57.9 degrees F, which was 0.9 degrees warmer than the 20th-century average of 57 degrees.
In the USA, what was...

18:45U.S. astronomers say a small galaxy 7 billion light-years from Earth, invisible to telescopes, may be completely made of dark matter, which reflects no light.
The distant and extremely small galaxy orbits as a satellite of a larger galaxy, they said.
Though telescopes are unable to observe the dwarf galaxy, scientists detected its presence through the tiny distortions its gravity causes in light passing near it, msnbc.com reported Wednesday.
Scientists think dark matter makes up about 98 percent of all matter in the universe but have been unable to detect it directly.
Dark objects like the tiny, distant galaxy could give clues to what exactly dark matter is and how it affects regular matter around it, they said.
Dwarf galaxies are found throughout the cosmos -- even our own Milky Way has them -- and our own galaxy's Sagittarius dwarf satellite is about the same size as the newly detected dark galaxy.
"For the first time we're getting information about something with a mass that's comparable to some of the smaller Milky Way satellites (like the Fornax and Sagittarius dwarfs) but outside of the local universe," study co-author David Lagattuta of the University of California, Davis, said.
"Add in the fact that it's something like 6 (billion) or 7 billion light-years away, it's really true that we've never been able to see something like this before."

18:45The leap second may live on for at least another three years. Once or twice a year, the leap second can be tacked on to synchronize atomic clocks -- the world's scientific timekeepers -- with the Earth's rotational cycle, which does not run quite like clockwork.
Without the leap second, atomic clocks would diverge about a minute a century from the course of the sun across the sky.
Britain, China, Canada and others have argued to keep it, but the United States, France and other nations have pushed to untether machines from the natural cycle because of the technical difficulties and costs to government and business.
Sanjay Acharya, a spokesman for the International Telecommunication Union, said Thursday a decision to abolish the leap second has been put off until next week. He said "it's been deferred" because government delegates at an ITU meeting were unable to reach agreement at talks this week.
The decision about how much the world needs the leap second affects everything from mobile phone networks to financial markets to air traffic control systems, all of which rely on atomic clocks and wouldn't have to momentarily stop their systems.
A Paris-based agency that tracks the globe's irregular wobble sends notice when the world's timekeepers need to add a leap second. That's only done on June 30 and December 31, but sometimes years go by without an adjustment -- and there's never been the need to subtract a leap second.
Government delegates now plan to examine the issue at a separate meeting in Geneva next week, but Acharya said they will likely defer any formal decision until 2015.
