- Important rice production system under pressure
In the face of growing pressure on one of Asia’s most important food production systems, experts are warning that farmers must get more help to make them more efficient.
Tue, 09 Oct 2007 23:54:55 -0500 - Mathematicians help unlock secrets of the immune system
A group of scientists, led by mathematicians, has taken on the challenge of building a common model of immune responses. Their work will radically improve our understanding of the human immune system by allowing all the scientific disciplines working on it to have a common reference point and language. The mathematicians, funded by the Biotechnology and Biological Sciences Research Council (BBSRC), will investigate how the different cellular components of the immune system work together and devise a theoretical and computational model that can be used by immunologists, mathematicians, computer scientists, physicists and engineers.
Tue, 09 Oct 2007 22:54:55 -0500 - Influenza: Insights into cell specificity of human vs. avian viruses
Researchers have identified which sites and cell types within the respiratory tract are targeted by human versus avian influenza viruses, providing valuable insights into the pathogenesis of these divergent diseases. The report by van Riel et al, “Human and avian influenza viruses target different cells in the lower respiratory tract of humans and other mammals,” appears in the October issue of The American Journal of Pathology and is accompanied by a commentary and highlighted on the cover.
Tue, 09 Oct 2007 21:54:55 -0500 - Researchers expand efforts to explore functional landscape of the human genome
The National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH), today announced grants totaling more than $80 million over the next four years to expand the ENCyclopedia Of DNA Elements (ENCODE) project, which in its pilot phase yielded provocative new insights into the organization and function of the human genome.
Tue, 09 Oct 2007 20:54:55 -0500 - Discovery of retinal cell type ends 4-decade search
A research team combining high-energy physicists from the University of California, Santa Cruz, and neuroscientists from the Salk Institute in La Jolla, Calif., has discovered a type of retinal cell that may help monkeys, apes, and humans see motion. The team's work appears in the October 10 issue of Journal of Neuroscience.
Tue, 09 Oct 2007 19:54:54 -0500 - Two more American Cancer Society researchers win Nobel Prize
Two of the three scientists receiving the 2007 Nobel Prize for Physiology or Medicine received funding from the American Cancer Society early in their careers, bringing to 42 the number of Nobel Laureates among the Society’s funded researchers.
Tue, 09 Oct 2007 18:54:56 -0500 - Study links chemical to inhibited milk synthesis, secretion in humans
University of Cincinnati (UC) researchers have identified the neurotransmitter serotonin as the chemical responsible for inhibiting milk production and secretion in human mammary glands.
Tue, 09 Oct 2007 14:44:27 -0500 - Newfound ancient African megadroughts may have driven the evolution of humans and fishes
From 135,000 to 90,000 years ago tropical Africa had megadroughts more extreme and widespread than any previously known for that region, according to new research.
Tue, 09 Oct 2007 12:44:27 -0500 - Which came first, the chicken genome or the egg genome?
Which came first, the chicken genome or the egg genome? Researchers have answered a similarly vexing (and far more relevant) genomic question: Which of the thousands of long stretches of repeated DNA in the human genome came first? And which are the duplicates?
Tue, 09 Oct 2007 10:44:27 -0500 - Plant viruses from past provide ecological clues
Taking the medical history of a grassland may seem a bit esoteric – after all, how sick can grass be? However, scientists have discovered plant viruses from as early as 1917 containing information crucial not only for plant scientists, but for those in ecology, human health and bioterrorism.
Mon, 08 Oct 2007 23:44:27 -0500 - Animal study identifies potential treatment for Huntington's disease
MassGeneral Institute for Neurodegererative Disorders (MIND) researchers have identified a compound that may lead to a treatment that could protect against the effects of Huntington’s Disease (HD). Their report, which will appear in the Proceedings of the National Academy of Sciences, describes how a small molecule called C2-8 appears to delay the loss of motor control and reduce neurological damage in a mouse model of the disorder. The study is receiving early online release.
Mon, 08 Oct 2007 22:44:26 -0500 - An AIDS-related virus reveals more ways to cause cancer, Penn researchers find
Researchers at the University of Pennsylvania School of Medicine have shed new light on how Kaposi’s Sarcoma-associated Herpes Virus (KSHV) subverts normal cell machinery to cause cancer. A KSHV protein called latency-associated nuclear antigen, LANA for short, helps the virus hide out from the immune system in infected cells. When LANA takes the place of other proteins that control cell growth, it can cause uncontrolled cell replication.
Mon, 08 Oct 2007 21:44:26 -0500 - Study shows genetically engineered corn could affect aquatic ecosystems
A study by an Indiana University environmental science professor and several colleagues suggests a widely planted variety of genetically engineered corn has the potential to harm aquatic ecosystems. The study is being published online this week by the journal Proceedings of the National Academies of Sciences.
Mon, 08 Oct 2007 20:44:26 -0500 - For honey bee queens, multiple mating makes a difference
The success of the “reign” of a honey bee queen appears to be determined to a large degree by the number of times she mates with drone bees.
