 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.

Triggering Muscle Development: A Therapeutic Cure For Muscle Wastage?
Scientists have shown that if elderly men who were given growth hormone and exercised their legs showed an appreciable muscle mass increase. Researchers say, "This raises the question: Can age-related loss of muscle strength and increased fragility be ameliorated by the therapeutic application of mechano growth factor?"

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.

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.
