Cold Spring Harbor, NY -- A four-year, multi-institutional effort co-led by three Cold Spring Harbor Laboratory (CSHL) scientists culminated today in publication of a landmark series of papers in the journal Science revealing in unprecedented detail the DNA sequence of maize (Zea mays).
WASHINGTON -- A suite of five ancient crocs, including one with teeth like boar tusks and another with a snout like a duck's bill, have been discovered in the Sahara by National Geographic Explorer-in-Residence Paul Sereno.
Research into the controversial drug thalidomide reveals that the mechanism through which the drug causes limb defects is the same process which causes it to damage internal organs and other tissues.
When Charles Darwin visited the Falkland Islands during the voyage of the Beagle in 1835, he saw a wolf-like species, wrote about it in his diaries and correctly commented that it was being hunted in such large numbers that it would soon become extinct.
The Congo Basin -- with its massive, lush tropical rain forest -- was far different 150 million to 200 million years ago.
LAKE ALFRED, FL -- Laser labeling of fruit and vegetables is a new, patented technology in which a low-energy carbon dioxide laser beam is used to label, or "etch" information on produce, thereby e
A genetic tendency to depression is much less likely to be realized in a culture centered on collectivistic rather than individualistic values, according to a new Northwestern University study.
A clever structure in the ear of a tropical butterfly that potentially makes it able to distinguish between high and low pitch sounds has been discovered by scientists from the University of Bristol, UK.
GAINESVILLE, Fla. -- A team of researchers including a University of Florida paleontologist has used a rich cache of plant fossils discovered in Colombia to provide the first reliable evidence of how Neotropical rainforests looked 58 million years ago.
AUSTIN, Texas -- Just as people plug in to computers, smart phones and electric outlets to communicate, electric fish communicate by quickly plugging special channels into their cells to generate electrical impulses, University of Texas at Austin researchers have discovered.
EAST LANSING, Mich. - It's been cultivated for at least 7,000 years and spread from South America to grow on every continent except Antarctica. Now the humble potato has had its genome sequenced.
Mathematicians from North America, Europe, Australia, and South America have resolved the first one trillion cases of an ancient mathematics problem on congruent numbers. The advance, which included work by David Harvey, an assistant professor at New York University's Courant Institute of Mathematical Sciences, was achieved through a complex technique for multiplying large numbers.
September 22, 2009 -- Mathematicians from North America, Europe, Australia, and South America have resolved the first one trillion cases of an ancient mathematics problem. The advance was made possible by a clever technique for multiplying large numbers. The numbers involved are so enormous that if their digits were written out by hand they would stretch to the moon and back.
Processes and policies governing the reuse and recycling of electronic products need to be standardized worldwide to stem and reverse the growing problem of illegal and harmful e-waste processing practices in developing countries, according to experts behind the world's first international e-waste academy.
