Cave dwelling nettle discovered in China Posted: 28 Dec 2012 10:37 AM PST British and Chinese botanists have discovered several new species of nettles growing in the entrance caverns of caves in 0.04 to 3 percent daylight. There has been little exploration of these caves for plants but recent studies are discovering many species new to science.

Early cognitive problems documented among those who eventually get Alzheimer's Posted: 28 Dec 2012 10:07 AM PST People who study or treat Alzheimer's disease and its earliest clinical stage, mild cognitive impairment (MCI), have focused attention on the obvious short-term memory problems. But a new study suggests that people on the road to Alzheimer's may actually have problems early on in processing semantic or knowledge-based information, which could have much broader implications for how patients function in their lives.

Hubble eyes the needle galaxy: IC 2233, one of the flattest galaxies known Posted: 28 Dec 2012 07:05 AM PST Like finding a silver needle in the haystack of space, the NASA/ESA Hubble Space Telescope has produced a beautiful image of the spiral galaxy IC 2233, one of the flattest galaxies known.

56% of female university students get drunk in record time, Spanish study suggests Posted: 28 Dec 2012 05:40 AM PST Researchers have studied university students' lifestyles; their analysis, which includes alcohol and illegal drug consumption habits, sport and food, concludes that most students indulge in unhealthy behavior. One of the main results of the study points to the high consumption of alcohol.

More serious earthquakes predicted in the Himalayas Posted: 28 Dec 2012 05:40 AM PST Scientists have discovered that massive earthquakes in the range of 8 to 8.5 magnitudes on the Richter scale have left clear ground scars in the central Himalayas. This ground-breaking discovery has huge implications for the area along the front of the Himalayan Mountains, given that the region has a population density similar to that of New York City.

Trying to halt hepatitis C's molecular hijacking Posted: 27 Dec 2012 02:33 PM PST Researchers have figured out intimate details of how the hepatitis C virus takes over an invaded cell, a breakthrough that could point to way for new treatments for the virus.

Staphylococcus aureus: Why it just gets up your nose Posted: 27 Dec 2012 02:33 PM PST Researchers have identified a mechanism by which the bacterium Staphylococcus aureus colonizes our nasal passages. The study shows for the first time that a protein located on the bacterial surface called clumping factor B has high affinity for the skin protein loricrin.

The factor that could determine future breast cancer treatment Posted: 27 Dec 2012 02:33 PM PST Australian scientists have shown how a 'transcription factor' causes breast cancer to develop an aggressive subtype that lacks sensitivity to oestrogen and does not respond to anti-oestrogen therapies such as Tamoxifen and aromatase inhibitors. Transcription factors are molecules that switch genes on or off. In this case, the transcription factor known as 'ELF5' inhibits sensitivity to oestrogen very early in the life of a breast cancer cell.

Scientists home in on cause of osteoarthritis pain Posted: 27 Dec 2012 02:30 PM PST Researchers have identified a molecular mechanism central to the development of osteoarthritis (OA) pain, a finding that could have major implications for future treatment of this often-debilitating condition.

Cholesterol drug shows promise in fighting effects of malaria Posted: 27 Dec 2012 02:30 PM PST Researchers have discovered that adding lovastatin, a widely used cholesterol-lowering drug, to traditional antimalarial treatment decreases neuroinflammation and protects against cognitive impairment in a mouse model of cerebral malaria.
