Scientists Find Mutations That Let Bird Flu Adapt To Humans
By comparing influenza viruses found in birds with those of the avian virus that have also infected human hosts, researchers have identified key genetic changes required for pandemic strains of bird flu. Biofuel Crops Double As Greenhouse-Gas Reducers
Corn and soybeans may be the current "go-to"crops for producing ethanol and biodiesel, respectively. But two other crops--switchgrass and hybrid poplar--could steal the show in the future when it comes to curbing greenhouse gases, according to Agricultural Research Service (ARS) and collaborating scientists. Cystic Fibrosis Proteins Photographed Interacting
New microscopic pictures show the first-ever physical evidence of interaction between two proteins involved in cystic fibrosis (CF) disease. UAB studied a CF-causing protein and another protein called epithelial sodium channel, or ENaC. Both proteins are known to play a role in CF, but exactly what role each plays is unclear. While On Trail Of Dioxin, Scientists Pinpoint Cancer Target Of Green T
Green tea appears to protect against cancer by affecting a "promiscuous"protein that pharmaceutical experts are already targeting in an effort to develop a new drug to stop the disease, scientists have found. Medical marijuana
“The US Food & Drug Administration’s (FDA) position on medical cannabis is incorrect, dishonest and a flagrant violation of laws requiring the government to base policy on sound science,” claims Joe Elford, Chief Counsel for patient advocacy group. The organisation, the largest of its type in the US promoting safe and legal access to cannabis [...] Early Images of Virginia Indians
Companion to an exhibit of prints of Native Americans made by Europeans in the late-16th and 17th centuries. Includes illustrated essays about interpreting historical images, invented scenes from narratives (such as the abduction of Pocahontas), and fanciful figures. From the Virginia Historical Society. Asymmetric Ashes: Astronomers Study Shape Of Stellar Candles
Astronomers are reporting remarkable new findings that shed light on a decade-long debate about one kind of supernovae, the explosions that mark a star's final demise: Does the star die in a slow burn or with a fast bang? From their observations, the scientists find that the matter ejected by the explosion shows significant peripheral asymmetry but a nearly spherical interior, most likely implying that the explosion finally propagates at supersonic speed. Infant Abuse Linked To Early Experience, Not Genetics
Intergenerational transmission of infant abuse is more likely caused by early experience than genetic inheritance, a new University of Chicago research on macaque monkeys shows."Maternal abuse of offspring in macaque monkeys shares some similarities with child maltreatment in humans, including its transmission across generations,"said Dario Maestripieri, an Associate Professor in the Department of Comparative Human Development at the University of Chicago. A New Method For Early Detection Of Disease Outbreaks
For disease outbreak detection, the public health community has historically relied on the watchful eyes of doctors, who have reported individual cases or clusters of cases of particular diseases to the authorities. But these days, the availability of electronic health-care data should facilitate more automated and earlier outbreak detection and intervention. Fat Is The New Normal
American women have gotten fatter as it has become more socially acceptable to carry a few extra pounds, according to a new study. The researchers suggest that weight norms may change and are not set standards based on beauty or medical ideals.
