Led by Newbury Astronomical Society, the Twitter Meteorwatch will take place from the evening of Tuesday August 11th until the morning of August 13th, 2009, covering the peak of the Perseids meteor shower.

At least one strain of the H5N1 avian influenza virus leaves survivors at significantly increased risk for Parkinson's disease and possibly other neurological problems later in life, according to new research.

Acupuncture has been used for over two millennia in East-Asian medicine to treat pain. Using brain imaging, researchers have provided novel evidence that traditional Chinese acupuncture affects the brain's long-term ability to regulate pain. Their findings show acupuncture acts as more than a placebo, and can activate receptors in the brain that process and dampen pain signals.

Cells of the immune system communicate using molecular messengers. One group of these substances are interferons. During a virus infection, the immune system increases the production of interferons such as Beta-Interferon, thus alerting immune cells to combat the infection. Furthermore, Beta-interferon also has tumor-fighting qualities and -- used as a therapeutic against multiple sclerosis -- is of major importance for medicine.

A growing research field is "global dimming" and "global brightening" of solar radiation. These phenomena, supposedly human-induced, control solar radiation incident at the Earth's surface and thus influence climate.
