(Eindhoven University of Technology) Researchers of Eindhoven University of Technology and the Radboud University Nijmegen in The Netherlands show for the first time why ordinary graphite is a permanent magnet at room temperature. The results are promising for new applications in nanotechnology, such as sensors and detectors. In particular graphite could be a promising candidate for a biosensor material. The results will appear online on October 4... More

Religious thinking is more associated with brain regions that govern emotion, self-representation, and cognitive conflict, while thinking about ordinary facts is more reliant upon memory retrieval networks, scientists at UCLA and other universities have found. They used fMRI to measure signal changes in the brains of committed Christians and nonbelievers as they evaluated the truth and falsity of religious and nonreligious propositions. For both g... More

Different patterns of training and learning lead to different types of memory formation, McGill University researchers have found in a study with the Aplysia mollusk.Spaced training, with trials distributed over time is superior at generating long-term memories than massed training, with trials presented at very short intervals, they found.

By disabling a gene involved in an important biochemical signaling pathway involving a protein called target of rapamycin (TOR), scientists have discovered a way to mimic the anti-aging benefits of caloric restriction, allowing mice to live longer and healthier lives. This finding offers a promising drug target for combating the many health problems associated with aging. (Source: http://www.technologyreview.com/biomedicine/23560/)

Scientists in the United Kingdom have found a way to get molecules to move quickly in a desired direction without help from outside forces, raising the possibility of coaxing cells to move and grow in specific directions to treat diseases. The scientists used a special surface with hydrophobic (water repelling) and hydrophilic (water-attracting) sections. The region between the two sections produced an "energy gradient" that can move nanoscale obj... More

The primary roles of consciousness are to bring together competing demands on skeletal muscle and decide which action "wins" and is carried out, and to allow individuals to adapt their actions in the future, according to San Francisco State University Assistant Professor of Psychology Ezequiel Morsella, lead author of a new study.The study finds that we are only aware of competing actions that involve skeletal muscles that voluntarily move parts o...

Human eyes can be used as detectors to observe quantum effects, University of Geneva physicists have found. Below a certain threshold number of incoming photons, the eye remains blind (no light is seen), whereas above the threshold, the probability of seeing) is close to one.How human eyes could detect quantum entanglement: A single-photon qubit is amplified through cloning via stimulated emission in a nonlinear crystal (red box). The clones are s... More
