|  Two-drug combo helps adolescents with ADHD, aggression  | Prescribing both a stimulant and an antipsychotic drug to children with physical aggression and attention-deficit/hyperactivity disorder (ADHD), along with teaching parents to use behavior management techniques, reduces aggressive and serious behavioral problems in the children, according to researchers. | Read More » How cells remove copper  | New research provides deeper insight into causes of serious diseases involving copper metabolism. Mapping the mechanism that regulates the transport of copper across the cell membrane and out of the body's cells actually provides a new understanding of conditions related to chronic imbalance in the body's level of copper. | Read More » Researchers develop new generation visual browser of epigenome  | ChroGPS is a software application that serves to facilitate the analysis and understanding of epigenetic data and to extract intelligible information, which can be downloaded free of charge in Bioconductor, a reference repository for biocomputational software. Scientists describe the uses of the program in a new article. | Read More » Clues to how plants evolved to cope with cold  | Researchers have found new clues to how plants evolved to withstand wintry weather. Scientists constructed an evolutionary tree of more than 32,000 species of flowering plants -- the largest time-scaled evolutionary tree to date. By combining their tree with freezing exposure records and leaf and stem data, the researchers were able to reconstruct how plants evolved to cope with cold as they spread across the globe. | Read More » Solar activity not a key cause of climate change, study shows  | Climate change has not been strongly influenced by variations in heat from the sun, a new scientific study shows. | Read More » Innovative screening strategy swiftly uncovers new drug candidates, new biology  | Scientists have demonstrated a drug-discovery strategy with a double payoff —- it enables the rapid selection of chemical compounds that have a desired effect on cells and also highlights how the compounds work. | Read More » Where Alzheimer's starts and how it spreads  | Using high-resolution fMRI imaging in patients with Alzheimer's disease and in mouse models of the disease, researchers have clarified three fundamental issues about Alzheimer's: where it starts, why it starts there, and how it spreads. In addition to advancing understanding of Alzheimer's, the findings could improve early detection of the disease, when drugs may be most effective. | Read More » Malaria drug target raises hopes for new treatments  | Scientists have taken an important step towards new malaria treatments by identifying a way to stop malaria parasites from multiplying. | Read More » Scientists anticipated size and location of 2012 Costa Rica earthquake  | Scientists using GPS to study changes in the Earth's shape accurately forecasted the size and location of the magnitude 7.6 Nicoya earthquake that occurred in 2012 in Costa Rica. | Read More » Greenland ice stores liquid water year-round  | Researchers have found an extensive reservoir in the Greenland Ice Sheet that holds water year round. A surprising discovery, the existence of the 27,000 square mile aquifer adds important information to sea level rise calculations. | Read More » Solitons in a crystal: New light source could serve in geo-navigation, search for Earth-like planets  | By creating an optical soliton in a microresonator, scientists have found a new light source that could serve in geo-navigation, telecommunications, spectroscopy and the hunt for new Earth-like planets. | Read More » Resistance makes waves  | Even physics can give pointers for energy saving. An international team is now in a position to provide materials scientists with tips for the development of high-temperature superconductors, in a bid to make them earn their name. The term is currently used to describe materials including ceramic cuprates, which lose their electrical resistance at significantly higher temperatures than conventional superconductors, but still well below the freezing point of water. | Read More » Getting excited helps with performance anxiety more than trying to calm down, study finds  | People who tell themselves to get excited rather than trying to relax can improve their performance during anxiety-inducing activities such as public speaking and math tests, according to a new study. | Read More » Motor excitability predicts working memory  | Humans with a high motor excitability have a better working memory than humans with a low excitability. By measuring the motor excitability, conclusions can be drawn as to the general cortical excitability – as well as to cognitive performance. Working memory allows the temporary storage of information such as memorizing a phone number for a short period of time. Studies in animals have shown that working memory processes among others depend on the excitability of neurons in the prefrontal cortex. | Read More » Thousand-year-old vineyards discovered in Alava, Spain  | Zaballa (Iruña de Oca) was a medieval settlement abandoned in the 15th century. The building of a manor monastery at the heart of it undermined the organization of the village in the 10th century with the creation of a highly significant rent-seeking system; it was later turned into a veritable factory, a specialised estate in the hands of local lords who, under the auspices of the economic boom in towns like Vitoria-Gasteiz, tried to obtain the maximum profits possible. In the end, the "flight" of its settlers towards the towns caused it to be abandoned. Today archaeologists are endeavoring to reconstruct and salvage our rural heritage by studying deserted settlements like Zaballa. | Read More » | |
