University of Utah researchers devised a way to watch newly forming AIDS virus particles “budding” from human cells without interfering with the process. The method shows a protein named ALIX gets involved during the final stages of virus replication, not earlier, as was believed previously.
Many dread a trip to the dentist but there are important things you need to do, and not do, in advance to have a successful visit. Communicating with your dentist before the visit is often critical. “If you have experienced a serious health condition such as a surgery or been diagnosed with a chronic condition, you need to tell your dentist before you come for your appointment,” says Martin Hogan, DDS, division director of dentistry at Loyola University Medical Center. “Depending on the illness, you may need to be premedicated with antibiotics to prevent infection.”

The findings appear in the current issue of the scientific journal Nature Neuroscience.
Research findings suggest there may be a simple way to reduce the risk of breast cancer by keeping cholesterol in check, either with statins or a healthy diet. Additionally, for women who have breast cancer and high cholesterol, taking statins may delay or prevent resistance to endocrine therapies such as tamoxifen or aromatase inhibitors.
Researchers at the Duke Cancer Institute have found that a byproduct of cholesterol functions like the hormone estrogen, fueling the growth and spread of the most common types of breast cancers.

The scientific spotlight focuses today on the healthful antioxidant substances in red wine, dark chocolate, olive oil, coffee, tea, and other foods and dietary supplements that are enticing millions of consumers with the promise of a healthier, longer life. The American Chemical Society, the world’s largest scientific society, is holding a symposium on those substances during its 246th National Meeting & Exposition.
The citrus flavor and aroma of grapefruit — already used in fruit juices, citrus-flavored beverages, and prestige perfumes and colognes — may be heading for a new use in battling mosquitoes, ticks, head lice and bedbugs thanks to a less expensive way of making large amounts of the once rare and pricey ingredient, a scientist said here today at the 246th National Meeting & Exposition of the American Chemical Society.
Key details of the way nerve cells in the brain remember pleasure are revealed in a study by University of Alabama at Birmingham (UAB) researchers published today in the journal Nature Neuroscience. The molecular events that form such “reward memories” appear to differ from those created by drug addiction, despite the popular theory that addiction hijacks normal reward pathways.
Researchers have found that a 260-million-year-old reptile is the earliest known version of the turtle. The discovery fills a large gap in the turtle fossil record and provide clues on how the turtle's unique shell evolved.

Unless Congress acts by this Friday, “a series of automatic cuts – called the sequester – will take effect that threaten hundreds of thousands of middle-class jobs, and cut vital services for children, seniors, people with mental illness and our men and women in uniform,” according to a White House report issued Sunday. Many Republican lawmakers, on the other hand, say President Obama and the Democrats are overstating the likely impact of the sequester.
