| Simpler lifestyle found to reduce exposure to endocrine-disrupting chemicals Posted: 26 Jun 2012 06:26 AM PDT A lifestyle that features fresh foods and limited use of products likely to contain environmental chemicals has been shown to reduce exposure to endocrine-disrupting chemicals (EDCs), such as BPA and phthalates, in a small population study. EDCs are linked to a number of adverse health complications including neuro-developmental delays, behavioral issues and fertility problems. They are produced by the millions of pounds per year and found extensively in a range of products that contain certain plastics. |
| Brewing the World’s Hottest Guinness Posted: 25 Jun 2012 04:03 PM PDT The positive and sometimes unexpected impact of particle physics is well documented, from physicists inventing the World Wide Web to engineering the technology underlying life-saving magnetic resonance imaging (MRI) devices. But sometimes the raw power of huge experiments and scientific ambition draw the recognition of those seeking only the most extreme achievements on Earth. |
| Posted: 25 Jun 2012 03:56 PM PDT Mineral evolution posits that Earth’s near-surface mineral diversity gradually increased through an array of chemical and biological processes. A dozen different species in interstellar dust particles that formed the solar system have evolved to more than 4500 species today. Previous work from Carnegie's Bob Hazen demonstrated that up to two thirds of the known types of minerals on Earth can be directly or indirectly linked to biological activity. |
| Greenland ice may exaggerate magnitude of 13,000-year-old deep freeze Posted: 25 Jun 2012 03:48 PM PDT Ice samples pulled from nearly a mile below the surface of Greenland glaciers have long served as a historical thermometer, adding temperature data to studies of the local conditions up to the Northern Hemisphere’s climate. But the method — comparing the ratio of oxygen isotopes buried as snow fell over millennia — may not be such a straightforward indicator of air temperature. |
| Neutrons explain haemoglobin evolution in red blood cells Posted: 25 Jun 2012 10:14 AM PDT Scientists have explained the evolutionary history of haemoglobin using what might seem an unlikely array of samples. Researchers focused the world’s most intense neutrons beams on the oxygen-carrying protein from a human, a duck-billed platypus, a chicken and a salt-water crocodile to explain how it has adapted to different body temperatures within different species. |
| Scientists twist light to send data Posted: 25 Jun 2012 09:57 AM PDT A multi-national team led by USC with researchers hailing from the U.S., China, Pakistan and Israel has developed a system of transmitting data using twisted beams of light at ultra-high speeds – up to 2.56 terabits per second. |
| Nano-Sandwich Technique Slims Down Solar Cells, Improves Efficiency Posted: 25 Jun 2012 08:29 AM PDT Researchers from North Carolina State University have found a way to create much slimmer thin-film solar cells without sacrificing the cells’ ability to absorb solar energy. Making the cells thinner should significantly decrease manufacturing costs for the technology. |
| Omega-3 lowers inflammation in overweight older adults Posted: 25 Jun 2012 08:19 AM PDT New research shows that omega-3 fatty acid supplements can lower inflammation in healthy, but overweight, middle-aged and older adults, suggesting that regular use of these supplements could help protect against and treat certain illnesses. |
| Solved at last - why spinach makes us strong Posted: 25 Jun 2012 06:36 AM PDT Nitrate, which is found naturally in spinach and other vegetables, has a powerful effect on muscle strength. Scientists at Karolinska Institutet have now uncovered how this happens by identifying two relevant proteins, the production of which is stimulated by the intake of nitrate. The study found that mice supplied with nitrate in their drinking water developed significantly stronger muscles - and this at doses obtainable from a normal diet. |
| You are where you e-mail: Global migration trends discovered in email data Posted: 25 Jun 2012 06:31 AM PDT For the first time comparable migration data is available for almost every country of the world. To date, records were incompatible between nations and especially by gender and age, nonexistent. Emilio Zagheni from the Max Planck Institute for Demographic Research (MPIDR) in Rostock, Germany, for the first time provides a rich migration database by compiling the global flow of millions of e-mails. |
| Mount Sinai researcher finds timing of ADHD medication affect academic progress Posted: 25 Jun 2012 06:28 AM PDT A team of researchers led by an epidemiologist at Mount Sinai School of Medicine and University of Iceland has found a correlation between the age at which children with attention-deficit/hyperactivity disorder (ADHD) begin taking medication, and how well they perform on standardized tests, particularly in math. |
| Exercise, even mild physical activity, may reduce breast cancer risk Posted: 25 Jun 2012 06:23 AM PDT A new analysis done by University of North Carolina at Chapel Hill researchers has found that physical activity – either mild or intense and before or after menopause – may reduce breast cancer risk, but substantial weight gain may negate these benefits. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the findings indicate that women can reduce their breast cancer risk by exercising and maintaining their weight. |
| Remapping gang turf: Math model shows crimes cluster on borders between rivals Posted: 25 Jun 2012 06:17 AM PDT A mathematical model that has been used for more than 80 years to determine the hunting range of animals in the wild holds promise for mapping the territories of street gangs, a UCLA-led team of social scientists reports in a new study. "The way gangs break up their neighborhoods into unique territories is a lot like the way lions or honey bees break up space," said lead author P. Jeffrey Brantingham, a professor of anthropology at UCLA. |
| Learn that tune while fast asleep Posted: 24 Jun 2012 06:23 PM PDT Want to nail that tune that you've practiced and practiced? Maybe you should take a nap with the same melody playing during your sleep, new provocative Northwestern University research suggests. The research grows out of exciting existing evidence that suggests that memories can be reactivated during sleep and storage of them can be strengthened in the process. |
