Researchers On The Path To Building Bone:
UAB (University of Alabama at Birmingham) researchers have developed a method to increase bone density in mice, a development that might have future benefit for humans in the treatment of osteoporosis and bone fracture. The research, published in the Jan. 29 issue of Proceedings of the National Academy of Sciences, involves manipulation of the Pten gene, which contributes to the process by which cells die, known as apoptosis.
Food-mood Connection: The Sad Are Twice As Likely To Eat Comfort Food:
People feeling sad tend to eat more of less-healthy comfort foods than when they feel happy, finds a new study co-authored by a Cornell food marketing expert. However, when nutritional information is available, those same sad people curb their hedonistic consumption. But happier people don't.
Huge Settlement Unearthed At Stonehenge Complex:
Excavations supported by National Geographic at Durrington Walls in the Stonehenge World Heritage site have revealed an enormous ancient settlement that once housed hundreds of people. Archaeologists believe the houses were constructed and occupied by the builders of nearby Stonehenge, the legendary monument on England's Salisbury Plain.
Dig Deeper To Find Martian Life:
Probes designed to find life on Mars do not drill deep enough to find the living cells that scientists believe may exist well below the surface of Mars, according to research led by UCL (University College London). Although current drills may find essential tell-tale signs that life once existed on Mars, cellular life could not survive the radiation levels for long enough any closer to the surface of Mars than a few metres deep -- beyond the reach of even state-of-the-art drills.
Evidence For Human-caused Global Warming Is Now 'Unequivocal':
The first major global assessment of climate change science in six years has concluded that changes in the atmosphere, the oceans and glaciers and ice caps show unequivocally that the world is warming. The Intergovernmental Panel on Climate Change (IPCC) concludes that major advances in climate modelling and the collection and analysis of data now give scientists "very high confidence" (at least a 9 out of 10 chance of being correct) in their understanding of how human activities are causing the world to warm. This level of confidence is much greater than what could be achieved in 2001 when the IPCC issued its last major report.
