USDA continues to work with the Canadian officials to verify traceback of the index animal. Records obtained from the owner correspond with Canada's records indicating that this animal was approximately 6-1/2 years old at the time of slaughter. USDA is working with Canada to conduct DNA testing to verify that the correct animal has been identified. The age of the animal is significant. She would have been born before feed bans were implemented in North America in August 1997. The feed bans prohibit the inclusion of ruminant protein in feed intended for other ruminants to eat. That practice has been identified time and time again as the primary means by which BSE spread.  more

Research shows that use of drugs, injected or not, can affect decisionmaking - particularly about engaging in unsafe sex - that can endanger one's health and the health of others.  more


Neuroscientists pinpoint midlife crisis in brain circuitry as key to brain aging and onset of Alzheimer's later in life

Researchers identify a gene that causes insulin resistance in Mexican Americans
For over a decade, scientists have known that insulin resistance a syndrome where the body does not respond as well as it should to insulin is linked to the development of heart disease, diabetes, high blood pressure, obesity and polycystic ovary syndrome. In fact, one in four adult Americans has insulin resistance, with Mexican Americans having the highest prevalence. But because people with insulin resistance are so likely to develop diseases such as diabetes and heart disease, scientists have turned their attention on investigating whether a common gene abnormality may be involved.  more

Blog, blog, blog
Blogging, or keeping a weblog, is often seen as a solitary effort. An individual can type frequent updates onto their log, sharing opinions or ideas with anyone with Internet access. The future of blogging could look a lot different.
