| 'Habitable' planet GJ 581d previously dismissed as noise probably does exist Posted: 06 Mar 2015 07:26 AM PST A new report has dismissed claims made last year that the first super-Earth planet discovered in the habitable zone of a distant star was 'stellar activity masquerading as planets.' The researchers are confident the planet named GJ 581d, identified in 2009 orbiting the star Gliese 581, does exist, and that last year's claim was triggered by inadequate analysis of the data.  |
| Evolving to cope with climate change Posted: 06 Mar 2015 07:26 AM PST Researchers have successfully measured the potential of the Atlantic Silverside to adapt to ocean acidification. This is the first such measurement for a vertebrate animal.  |
| New flexible films for touch screen applications achieve longer lasting display Posted: 06 Mar 2015 07:25 AM PST Today, touch screens are everywhere, from smart phones and tablets, to computer monitors, to interactive digital signage and displays. Many touch screens are made of layered thin (billionths of a meter thick) films of indium-tin oxide, an inorganic material that is electrically conductive, which allows electrical signals to travel from the "touch" to the edges of the display, where they are sensed by the device--as well as optically transparent. But these and other inorganic materials have a downside, as anyone who has ever dropped their smart phone knows: they are brittle and shatter easily. The solution? Make the screens flexible and durable without sacrificing any of their electrical or optical properties. Researchers have now created thin sheets of hybrid materials that may enable the next generation of consumer electronics.  |
| Investigational osteoporosis drug, abaloparatide, lowers fracture risk Posted: 06 Mar 2015 07:25 AM PST Abaloparatide-SC, an injectable drug being studied for the treatment of postmenopausal osteoporosis, reduces the rate of new spinal fractures by a statistically significant 86 percent and as well as statistically significant reductions in the fracture rate at other parts of the body, a phase 3 clinical trial finds.  |
| High-normal thyroid hormone level in pregnancy may affect fetal brain development Posted: 06 Mar 2015 07:25 AM PST A new study finds that not only low but also high maternal thyroid hormone levels during early pregnancy may significantly lower the infant's IQ later in childhood.

| Researchers create artificial methane hydrates, open an innovative pathway for use of new fuels Posted: 06 Mar 2015 04:38 AM PST A technology that allows the preparation of artificial methane hydrates has been developed by researchers. These researchers have demonstrated that it is possible to prepare methane hydrates in a laboratory by imitating, and even enhancing, natural processes through the use of activated carbon materials as nano-reactors. One of the keys of this research was that scientists were able to reduce the process to form methane hydrates, which takes a long time in nature, to just a few minutes, thus making its technological applicability much easier.  |
| Researchers connect climate change to food safety Posted: 06 Mar 2015 04:38 AM PST Climate change can affect our food safety in a number of ways. In a European study, researchers state that there is often a relationship between long-term changes in temperature and rainfall and vegetable and fruit contamination. For example, flooding may result in increased concentrations of harmful bacteria that can be quickly broken down again by UV light. Similarly, in one region fungi that produce toxins may increase due to global warming, while they decrease in other regions.  |
| New findings on 'key players' in brain inflammation Posted: 06 Mar 2015 04:38 AM PST Inflammatory processes occur in the brain in conjunction with stroke and neurological diseases such as Alzheimer's and Parkinson's disease.

| Karnak: Excavation yields 38 artifacts Posted: 06 Mar 2015 04:38 AM PST The excavation of a favissa, a pit discovered in early December 2014 near the temple of the god Ptah, has been completed. The dig has unearthed 38 statues, statuettes and precious objects, making this an exceptional find, both for the quantity and quality of the religious artifacts brought to light. Furthermore, a completely new recording method was used during the dig that makes it possible to virtually reconstruct each step of the discovery with millimeter accuracy.  |
| Mice don't need the cortex to sing their songs Posted: 06 Mar 2015 04:37 AM PST The human language is unique in that we can refer to objects, events and ideas. The combination of syllables and words enables humans to generate an infinite number of expressions. An important prerequisite for language is the ability to imitate sounds, i.e. to store acquired acoustic information and to use this for one's own vocal production. Cortical structures in the brain play a crucial role in this. While songbirds and certain marine mammals are capable of such vocal learning, there is very little evidence for vocal learning in terrestrial mammals -- not even in our closest living relatives, the chimpanzees. Nonhuman primate vocal production is largely restricted to an innate repertoire of sounds.  |
| Moves to automate identification of Saimaa ringed seals Posted: 06 Mar 2015 04:37 AM PST Moves are being made to automate the identification of Saimaa ringed seals. This would bring new kinds of real-time information on how the extremely endangered species behaves, the movements of individual seals, and what happens to them. The final aim of an ongoing study on machine vision is to get a biometric passport for each individual Saimaa ringed seal. This happens on the basis of the unique fur patterns of each individual seal, using computer-based smart calculation and digital image processing. The aim is to store the information in a so-called Saimaa ringed seal database.  |
| Green lungs of our planet are changing Posted: 06 Mar 2015 04:37 AM PST Are leaves and buds developing earlier in the spring? And do leaves stay on the trees longer in autumn? Do steppe ecosystems remain green longer and are the savannas becoming drier and drier? In fact, over recent decades, the growing seasons have changed everywhere around the world, according to research based on satellite data. The results are expected to have consequences for agriculture, interactions between species, the functioning of ecosystems, and the exchange of carbon dioxide and energy between the land surface and the atmosphere.  |
| Brain treats real and imaginary objects in the same way Posted: 06 Mar 2015 04:37 AM PST The human brain can select relevant objects from a flood of information and edit out what is irrelevant. It also knows which parts belong to a whole. If, for example, we direct our attention to the doors of a house, the brain will preferentially process its windows, but not the neighbouring houses. Psychologists have now discovered that this also happens when parts of the objects are merely maintained in our memory.  |
| Infant growth affected by exposure to environmental pollutants Posted: 06 Mar 2015 04:37 AM PST Even though the levels of two environmental pollutants have declined over the last 20 years, they may still have adverse effects on children's development, according to a new study. The researchers found that maternal levels of DDE (indicating the levels to which the fetuses were exposed to in utero) were significantly associated with rapid growth in early life. They also found that levels of PCB153 in milk and the amount transferred through breastfeeding were associated with decreased infant growth and falling below expected growth curves.  |
| Teenage TV audiences and energy drink advertisements Posted: 06 Mar 2015 04:36 AM PST Researchers have examined a database of television advertisements broadcast between March 2012 and February 2013 on 139 network and cable channels and found that more than 608 hours of advertisements for energy drinks were aired. Nearly half of those advertisements, 46.5%, appeared on networks with content themes likely to appeal to adolescents.  |
| Autism detection improved by multimodal neuroimaging Posted: 06 Mar 2015 04:36 AM PST Combined measurements of brain anatomy, connectivity and neurochemistry distinguish autism spectrum disorder subjects from controls, scientists say. This multimodal approach is distinct from many previous studies that have used a single neuroimaging measure. While those studies uncovered widespread functional and anatomical brain abnormalities in ASD, the results were not highly consistent, possibly reflecting the complex brain pathology in autism spectrum disorders.  |
| Popular antioxidant likely ineffective, study finds Posted: 06 Mar 2015 04:36 AM PST The popular dietary supplement ubiquinone, also known as Coenzyme Q10, is widely believed to function as an antioxidant, protecting cells against damage from free radicals. But a new study finds that ubiquinone is not a crucial antioxidant.  |
