For those who find the vast array of high-tech hardware that fills the National Air and Space Museum overwhelming -- not to mention the constant hordes that fill the cavernous expanse -- a more serene and equally informative scientific experience is available less than a mile away at the largely...

Tuesday's announcement that scientists had found a noncontroversial way to make cells equivalent to human embryonic stem cells did not just change the scientific and ethical landscape. It generated economic and geopolitical tremors through California, New York and about half a dozen other states...
The discovery that it is possible to create equivalents to embryonic stem cells without destroying embryos has the potential to reshape -- and perhaps defuse -- the acrimonious political debate that has raged ever since human embryonic stem cells were discovered in 1998.
Researchers in Wisconsin and Japan said yesterday that they have turned ordinary human skin cells into what are effectively embryonic stem cells without using embryos or women's eggs -- the previously essential ingredients that have embroiled the medically promising field in a nearly decade-long ...
After decades of declining death ratesfrom heart disease, a new study shows that more women under 45 are now dying because of clogged arteries while the death rate for men that age has leveled off. Heart experts are not sure why, but they think increasing obesity and other risk factors are to...
Climate change may be global in its sweep, but not all of the globe's citizens will share equally in its woes. And nowhere is that truth more evident, or more worrisome, than in its projected effects on agriculture.
Hundreds of defendants sitting in prisons nationwide have been convicted with the help of an FBI forensic tool that was discarded more than two years ago. But the FBI lab has yet to take steps to alert the affected defendants or courts, even as the window for appealing convictions is closing, a j...
The world will have to end its growth of carbon emissions within seven years and become mostly free of carbon-emitting technologies in about four decades to avoid killing as many as a quarter of the planet's species from global warming, according to top United Nations' scientists.
LONDON -- The Scottish scientist who created Dolly the sheep more than a decade ago said he is abandoning the cloning technique that he pioneered, according to an interview published Saturday.
Global warming is destroying species, raising sea levels and threatening millions of poor people, the United Nations' top scientific panel will say today in a report that U.N. officials hope will help mobilize the world into taking tougher actions on climate change.
