Some Species Rebound, But More Become Endangered

The global crisis for endangered species is more serious than the financial meltdown, with numbers of imperiled animals and plants rising at record rates, scientists are warning in a report released today.In its latest four-year assessment of endangered species, the International Union for Conservation of Nature (IUCN) has added several new entries to the Red List of Threatened Species. Judging from the list's expansion, the report warns, the world is unlikely to meet a goal of reversing a trend toward species depletion by 2010. [More]

Predicting The Return Of Prostate Cancer: New Study Betters The Odds Of Success

Cancer experts say a study tracking 774 prostate cancer patients for a median of eight years has shown that a three-way combination of measurements has the best chance yet of predicting disease metastasis.

Methane-producing Molecule Can Also Repair DNA

The Archaea are single-celled organisms and a domain unto themselves, quite apart from the so called eukaryotes (bacteria and higher organisms). Many species live under extreme conditions, and carry out unique biochemical processes shared neither with bacteria nor with eukaryotes. Methanogenic archaeans, for example, can produce methane gas out of carbon dioxide and hydrogen.

Overweight Kids Experience More Loneliness, Anxiety

Police Work Undermines Cardiovascular Health, Comparison To General Population Shows

It is well documented that police officers have a higher risk of developing heart disease: The question is why. In the most recent results coming out of one of the few long-term studies being conducted within this tightly knit society, researchers have determined that underlying the higher incidence of subclinical atherosclerosis -- arterial thickening that precedes a heart attack or stroke -- may be the stress of police work.

Risk Of Liver Cancer In Women With Hepatitis B Virus Infection Varies With Number Of Pregnancies

Risk for hepatocellular carcinoma, a primary malignancy of the liver, was statistically significantly higher among women with hepatitis B virus (HBV) infection than among women without the virus, according to a new study.

Mars More Like Earth Than Thought? New Details About History Of Water On Red Planet

New details have emerged about the history of water on Mars, gleaned from the 2008 NASA Phoenix Mars Mission. Scientists found patterns in the ground near the lander, multi-sided shapes about three to ten meters in size. The shapes are created when the surface contracts and the ice cracks. Sand fills in the cracks before the ice expands and buckles the surface to make the distinctive patterns.
