Enhance-athon: Shoot Straighter
Old hat at first-person shooters but new to rifle ranges, Clive Thompson tries to improve his aim. The goal? Ten bull's-eyes in a row. Neurotransmitters Signal Aggressive Cancer, Offer Potential For Early
Nerves talk to each other using chemicals called neurotransmitters. One of those "communication chemicals,"aptly named GABA (gamma amino butyric acid), shows up in unusually high amounts in some aggressive tumors, according to a new study from Washington University School of Medicine in St. Louis. How Humid Is It? Simple Conversion Between Relative Humidity And Dew P
A researcher at the Max Planck Institute for Chemistry in Mainz, Germany, has suggested a very simple formula for converting between the relative humidity and the dew point temperature without needing a calculator, which makes it much easier to determine expected comfort levels and cloud base altitudes on humid days.

Some molecular interactions on cell surfaces may have a "memory"that affects their future interactions. The report could lead to a re-examination of results from certain single-molecule research. Improving Cancer Diagnosis
Researchers have developed a new way of detecting the abnormal presence of complexes of sugars and proteins in the blood of cancer patients, thus providing a new tool for cancer diagnosis. Many proteins on the surface of cells have sugars attached to them, which helps the cells bind with one another and communicate among one another. But in cancer, these cell surface proteins can have an abnormally high number of sugar molecules attached to them. No Risk, No Fun? People Who Take Risks More Satisfied With Their Lives
Tall people are more prepared to take risks than small people, women are more careful than men, and the willingness to take risks markedly decreases with age: These are the findings arrived at by researchers from the Institute for the Study of Labor (IZA), the University of Bonn and the German Institute for Economic Research (DIW) in Berlin. Exercise Stimulates The Formation Of New Brain Cells
Exercise has a similar effect to antidepressants on depression. This has been shown by previous research. Now Astrid Bjørnebekk at Karolinska Institutet has explained how this can happen: Exercise stimulates the production of new brain cells. New Weapon Against Cancer: HIV Protein Enlisted To Help Kill Cancer Ce
Cancer cells are sick, but they keep growing because they don't react to internal signals urging them to die. Now researchers at Washington University School of Medicine in St. Louis have found an efficient way to get a messenger into cancer cells that forces them to respond to death signals. And they did it using one of the most sinister pathogens around -- HIV. Environmental Factors Early In Life May Influence Testicular Cancer Ri
The risk of testicular cancer was significantly lower among first-generation immigrants to Denmark, compared with men born in Denmark to immigrant parents and Danish men with Danish parents, according to a study published online December 25 in the Journal of the National Cancer Institute. This suggests that early exposure to environmental factors may influence the development of the disease.
