Secret of life on Earth may be as simple as what happens between the sheets -- mica sheets, that is (August 6, 2010) -- That age-old question, "where did life on Earth start?" now has a new answer. If the life between the mica sheets hypothesis is correct, life would have originated between sheets of mica that were layered like the pages in a book. ... > full story
Encouraging data on preventing Crohn's disease recurrence (August 6, 2010) -- Biological agents may play an important role in maintaining remission in Crohn's disease, according to two new studies. ... > full story
Selenium makes more efficient solar cells (August 6, 2010) -- By embedding the element selenium in zinc oxide, researchers have made a relatively inexpensive material that could be promising for solar power conversion by making more efficient use of the sun's energy. ... > full story
How cells make specific interactions during development (August 6, 2010) -- Researchers have shed new light on how cells make specific interactions during development -- in the hope of one day learning more about human developmental disorders. ... > full story
Image of new antibiotic in action opens up new opportunities to combat antibacterial resistance (August 6, 2010) -- Detailed pictures reveal how a new type of experimental antibiotic can kill bacteria that are already resistant to existing treatments. The findings could ultimately help scientists to develop new antibiotics to tackle the bacteria responsible for many hospital and community-acquired infections. ... > full story
Worst impact of climate change may be how humanity reacts to it (August 6, 2010) -- The way that humanity reacts to climate change may do more damage to many areas of the planet than climate change itself unless we plan properly, an important new study by a group of leading scientists has concluded. ... > full story
Newts' ability to regenerate tissue replicated in mouse cells (August 6, 2010) -- Scientists have taken a big step toward being able to confer a regenerative capacity on mammalian muscle cells; they accomplished this feat in experiments with laboratory mice in which they blocked the expression of just two tumor-suppressing proteins. The finding may move us closer to future regenerative therapies in humans -- surprisingly, by sending us shimmying back down the evolutionary tree. ... > full story
Novel bee venom derivative forms a nanoparticle 'smart bomb' to target cancer cells (August 6, 2010) -- The next time you are stung by a bee, here's some consolation: a toxic protein in bee venom, when altered, significantly improves the effectiveness liposome-encapsulated drugs or dyes, such as those already used to treat or diagnose cancer. This research shows how modified melittin may revolutionize treatments for cancer and perhaps other conditions, such as arthritis, cardiovascular disease, and serious infections. ... > full story
Reading zip codes of 3,500-year-old letters: Non-destructive X-ray scanning of archaeological finds (August 6, 2010) -- A researcher in Israel uses a hand-held device based on x-ray fluorescence, a device that can be found in many chemistry labs, to non-destructively ascertain the chemical composition of ancient tablets. Using an index that he's developed, he can determine the geographical origin of coins, ancient plasters, glass and tablets to investigate the secrets of ancient history. ... > full story
Non-human primate study generates information relevant to HIV-1 vaccine strategies (August 6, 2010) -- Monkeys repeatedly immunized with a particular form the HIV-1 envelope glycoprotein generated antibodies capable of neutralizing diverse strains of HIV-1, according to a paper published online in the Journal of Experimental Medicine on August 2. ... > full story
A 'crystal ball' for predicting the effects of global climate change (August 6, 2010) -- In trying to predict how species will respond to climate change caused by global warming, researchers and scientists are turning to comparative physiology, a sub-discipline of physiology that studies how different organisms function and adapt to diverse and changing environments. Overall, the comparative approach gives researchers insights into the effects of global warming that they wouldn't otherwise have. ... > full story
Children's vegetable intake linked to Popeye cartoons (August 6, 2010) -- Popeye cartoons, tasting parties and junior cooking classes can help increase vegetable intake in kindergarten children, according to new research. Researchers in Thailand found the type and amount of vegetables children ate improved after they took part in a program using multimedia and role models to promote healthy food. ... > full story
