Self-fertility In Fungi: The Secrets Of 'DIY Reproduction'
New light has been shed on a fascinating phenomenon of the natural world -- the ability of some species to reproduce sexually without a partner. When sex occurs the fungus activates its internal sexual machinery and in essence 'mates with itself'to produce new offspring, rather than bypassing the sexual act. Cranberries May Improve Chemotherapy For Ovarian Cancer
Compounds in cranberries may help improve the effectiveness of platinum drugs that are used in chemotherapy to fight ovarian cancer, researchers have found in a controlled laboratory study. The scientists found that human ovarian cancer cells resistant to platinum drugs became up to six times more sensitized to the drugs after exposure to the cranberry compounds. Rocking Tunes Without the Tangles
A new car kit points toward the next hot trend in mobile audio: wireless music playback from phones and MP3 players using Bluetooth's A2DP profile. In Listening Post. Large Asteroid Breakup May Have Caused Mass Extinction On Earth 65 Mil
The impactor believed to have wiped out the dinosaurs and other life forms on Earth some 65 million years ago has been traced back to a breakup event in the main asteroid belt. A joint U.S.-Czech team from Southwest Research Institute (SwRI) and Charles University in Prague suggests that the parent object of asteroid (298) Baptistina disrupted when it was hit by another large asteroid, creating numerous large fragments that would later create the Chicxulub crater on the Yucatan Peninsula as well as the prominent Tycho crater found on the Moon. NIST Method Improves Reliability Of GPS Clocks
A statistical method, developed by the National Institute of Standards and Technology (NIST) and tested and implemented with the help of several collaborators, has made the job of analyzing the accuracy and reliability of Global Positioning System time signals significantly faster and easier. The method will help ensure that GPS clocks produce accurate location and distance measurements and remain closely synchronized with official world time.
First Step Towards A Non-invasive Screening Test For Early Signs Of Te
Researchers in Denmark have discovered a way to detect early signs of testicular cancer before it has started to spread. Their findings are the first step towards developing a simple screening test for men at risk of the disease. Chemotherapy Errors Rare, But Have Potential For Serious Consequences
About one out of 30 chemotherapy orders at three ambulatory infusion clinics had errors, and one in 50 orders had a serious error, according to a new study. The study, performed at the Dana-Farber Cancer Institute, found most but not all errors were detected before they reached the patient. None was life-threatening or caused patient harm. Still, an accompanying editorial says the study underscores the need to implement safer controls of drug ordering and dispensing at chemotherapy infusion clinics. Squarks, Bosons and Zinos, Oh My!
The world's biggest collider hopes to create a smorgasbord of exotic particles, from the so-called God particle to dark matter and maybe even miniature black holes. John Borland goes to the edge of theory. Short Film Shot Entirely on Flatbed Scanner

 HIV's Cellular Kiss Of Death Explains Loss Of Uninfected T Cells In AI
In AIDS, CD4+ T cells are killed by direct HIV infection but researchers remain puzzled as to why uninfected CD4+ T cells also die. A new JCI study shows that an HIV surface glycoprotein expressed by HIV-infected CD4+ T cells interacts with the receptor CXCR4 on the surface of uninfected CD4+ T cells, causing autophagy-mediated cell death. This may explain why the number of uninfected CD4+ T cells is depleted in AIDS patients.
