While fear memory -- or the ability to remember contexts in which to be afraid -- is important for survival, too much of it, and an inability to forget contexts that no longer apply, hinders daily activities. Recently, scientists from Japan found that a certain opioid drug can help mask some fear memory without causing undesirable side effects. This could make new therapies possible for anxiety disorders like phobias or PTSD.
Policies regulating fishing in international waters do not sufficiently protect officials who monitor illegal fishing, the prohibited dumping of equipment, or human trafficking or other human rights abuses, finds a new analysis by a team of environmental researchers.
Researchers have demonstrated a new, green technology for both accelerated screening and retrieving 'switchable' solvents used in green chemistry applications. The new approach makes the screening process hundreds of times faster and drastically accelerates the rate at which solvents can be retrieved from solution.
One of South America's most prominent volcanoes is producing early warning signals of a potential collapse, new research has shown.
It is like jumping on and off a carousel: what happens to neutrons changing from a non-rotating frame of referendce into a rotating frame of reference -- and back? 30 years ago, scientists predicted that this would lead to interesting interference effects, because neutron spin show a special kind of inertia. Now, this has been verified in an experiment.
Hebrew University team unearths Canaanite temple at Lachish; find gold artifacts, cultic figurines, and oldest known etching of Hebrew letter 'Samech.'
An international team of researchers carried out an experiment at HSE University demonstrating that knowledge of several languages can improve the performance of the human brain. In their study, they registered a correlation between participants' cognitive control and their proficiency in a second language.
Scientists at Tokyo Institute of Technology designed a new type of controller for the robotic arm used in robotic surgery. Their controller combines the two distinct types of gripping used in commercially available robotic systems to leverage the advantages of both, reducing the efforts of the surgeon and providing good precision.
Making artificial structures that emit light tailored to our specific needs is an even more attractive proposition. However, light emission in a semi-conductor only occurs when certain conditions are met. Researchers (UNIGE) have discovered an entire class of two-dimensional materials that are the thickness of one or a few atoms. When combined together, these atomically thin crystals are capable of forming structures that emit customizable light in the desired color.
Scientists at Tokyo Tech demonstrate the first visible-light photoelectrochemical system for water splitting using TiO2 enhanced with an earth-abundant material -- cobalt. The proposed approach is simple and represents a stepping stone in the quest to achieve affordable water splitting to produce hydrogen, a clean alternative to fossil fuel.
