The U.S. Department of Agriculture's Agricultural Research Service have announced initial results of a research project involving prion-free cattle. ARS scientists evaluated cattle that have been genetically modified so they do not produce prions, and determined that there were no observable adverse effects on the animals' health. Read more…
As I've mentioned before, the last plantation I worked in Malaysia before migrating to Australia was situated near the town of Sitiawan. In my very first boundary patrol however, I was shocked to notice a strange rock formation at the back of the plantation. Read more…

AP - After clambering down a canyon wall, ducking poison ivy vines and wading chest-deep across a lukewarm stream, Cary Myler spied some flecks that look like pepper sprinkled on a wet rock and announced, "Found some." Read more…
The FDA says no special labels are needed to identify cloned beef. Just more of the same lousy product. Read more…
A brain hormone linked to the onset of puberty in teens also appears to turn down the Siberian hamster's libido and reproduction during winter months, scientists report. Read more…
New research has brightened the prospects for using nanodiamonds as drug carriers, implant coatings, nanorobots and other medical applications that take advantage of diamond nanoparticles' attractive properties. Read more…
A new method for detecting cyanide in drinking water and other sources offers numerous advantages over cumbersome existing technology, scientists report in an article scheduled for the Jan. 1 issue of ACS' Analytical Chemistry, a semi-monthly journal. Read more…
A new study led by a scientist at Children's Hospital Oakland Research Institute (CHORI) is the first to conclude that Chlamydia trachomatis is evolving at a rate faster than scientists first thought or imagined. Chlamydia trachomatis is a bacterium that is the leading cause of sexually transmitted diseases and the second leading cause of blindness worldwide. Scientists believe the bacterium is evolving through a process called recombination where genes from one or more strains combine to create new strains and -- theoretically -- new diseases. Read more…
Researchers at UCSD School of Medicine have identified a genetic regulator of brain development that sheds new light on how immature neural cells choose between proliferation and differentiation. Defects in regulating this choice result in brain malformations. Their research will be published on line the week of December 4, in advance of publication in the Proceedings of the National Academy of Sciences (PNAS). Read more…
A new research approach that allowed scientists to rapidly identify the gene responsible for high sodium levels in certain naturally occurring plant populations could have applications for the study of a wide variety of other important plant properties. Read more…
A study published in the Jan. 1 issue of the journal Sleep finds that sleep disturbances are common among suicide attempters, and that nightmares are associated with suicidality. Read more…
Wild birdseed contained higher levels of aflatoxins and other mycotoxins than any other kind of pet food analyzed in studies done around the world, a new review of those studies reports in an article scheduled for the Dec. 27 issue of ACS' Journal of Agricultural and Food Chemistry. Read more…
Bacterial resistance to antibiotics is a major challenge for the current treatment of infectious diseases. One way bacteria can escape destruction is by pumping out administered drugs through specific transporter proteins that span the cell membrane, such as AcrB. Read more…
An innovative combination of existing technologies shows promise for noninvasive, high-resolution imaging of cartilage in research on the progression and treatment of the common degenerative disease osteoarthritis. Read more…
A comprehensive review published in the Jan. 1 issue of the journal Sleep finds that, as with other diseases characterized by selective cell loss, narcolepsy may be caused by environmental exposures before the age of onset in genetically susceptible individuals. Read more…
Researchers in the U.S. and Malaysia have discovered a new species of lizard while conducting field research in Borneo. Using DNA sequencing, the scientists confirmed their finding by analyzing the genetic code of the new lizard along with that of related species. Read more…
AP - A pair of scimitar-horned oryxes from the Kansas City Zoo are among six from North America and four from Europe that are being reintroduced in Tunisia, the animals' native scrubland where they have been wiped out. Read more…
AP - A federal study beginning this month will examine how much the Savannah River's bustling shipping channel contributes to beach erosion on Tybee Island. Read more…
AP - While most weather forecasters focus on the six or seven miles of earth's atmosphere where clouds drift and storms form, Jonathan Makela's sights are set much higher. Read more…
AP - A man hunting for American Indian artifacts with his sons along a gravel bar on the Missouri River has uncovered an ancient fishhook that is making collectors envious. Read more…
AP - Researchers say their discovery of a 2,000-year-old toilet at one of the world's most important archaeological sites sheds new light on whether the ancient Essene community was home to the authors of many of the Dead Sea Scrolls. Read more…
