Science Glance
In a step that has implications for stem cell research, human biology and the treatment of disease, researchers in Japan and at Harvard University have managed to turn adult cells back into flexible stem cells without changing their DNA.
The researchers discovered that they could put cells in various challenging circumstances – including in acidic solutions and under physical pressure – and turn mature blood cells into cells that were capable of turning into virtually any cell in the body.

New Atomic Clock Would Stay Accurate Till The End Of Time
Today's quartz wristwatches are pretty darn good at keeping time, gaining or losing only about 15 seconds a month.
But a new atomic clock -- an experimental device described in a paper in the journal Nature -- is a bit better. Tests show it wouldn't gain or lose even a single second over the course of 5 billion years. That's a new world record.
The "strontium lattice" clock was created by researchers led by Dr. Jun Ye, a physicist with the National Institute of Standards and Technology (NIST). It is housed at JILA, an institute operated by NIST and the University of Colorado at Denver, according to a written statement released by the institute. It's about 50 percent more precise than the previous world record-holder, NIST's so-called "quantum logic" clock.
Scale Of Universe Revealed In New Ultraprecise Galaxy Map
An ultraprecise new galaxy map is shedding light on the properties of dark energy, the mysterious force thought to be responsible for the universe's accelerating expansion.
A team of researchers working with the Baryon Oscillation Spectroscopic Survey (BOSS) has determined the distances to galaxies more than 6 billion light-years away to within 1 percent accuracy — an unprecedented measurement.
"There are not many things in our daily lives that we know to 1-percent accuracy," David Schlegel, a physicist at Lawrence Berkeley National Laboratory and the principal investigator of BOSS, said in a statement. "I now know the size of the universe better than I know the size of my house." [The History & Structure of the Universe (Infographic)]
Fla. space center home to secret spacecraft
An undisclosed number of workers will recover, refurbish and relaunch the 29-foot-long unmanned spacecraft.
The Air Force launched the most recent flight of the unmanned spacecraft from Florida's Space Coast more than a year ago.
Bill Nye (the Science Guy) to visit Creation Museum for debate
Bill Nye "The Science Guy" is set to visit Kentucky to debate evolution and biblical creation with the founder of the Creation Museum.
Ken Ham wrote on his Facebook page Thursday that he will square off Feb. 4 with Nye, the former host of a popular science TV show for youths.
The event is likely to attract plenty of attention in scientific and faith circles, as Nye is a high-profile advocate of science education and Ham is a respected leader among Christians who believe the Bible's origin story is a factual account of the Earth's beginnings.
Scientists find records of rare "earthquake lights"
They've been mistaken for UFOs or dismissed as hallucinations. Now geologists have collected a near-definitive list of a rare but fascinating phenomenon — earthquake lights.
Certain types of earthquakes in certain areas can set off blazes of light seconds — sometimes days — ahead of the actual quake. These can manifest themselves as floating balls of light, bluish columns shooting up out of the earth and even reverse lightning, reaching up into the sky from the ground.
Surprising Number Of Americans Still Don't Believe In Evolution
One in three Americans doesn't believe in evolution, according to new survey results from the Pew Research Center.
The results, released Monday in report on views about human evolution, show that 33 percent of Americans think "humans and other living things have existed in their present form since the beginning of time."
