This research focused on key components of the brain known as NMDA receptors. These receptors are located on nerve cells in the brain and serve as biochemical gates that allow calcium ions (electrical charges) to enter the… read more

Howard Hughes Medical Institute (HHMI) scientists have found a way to silence (turn off) individual neurons, using optogenetics, which previously could only turn on neurons.
Optogenetics is a method used by neuroscientists to study how specific neurons work. They shine LED or laser light on genetically modified neurons (light-activated) proteins (such as channelrhodopsin) that function as ion channels, which then turn on the… read more
A chemical system developed by researchers at the University of Illinois at Chicago can efficiently perform the first step in the process of creating synthetic gasoline (syngas) and other energy-rich products out of carbon dioxide.
The key to the new process is a novel “co-catalyst” system using inexpensive, easy-to-fabricate carbon-based nanofiber materials that efficiently convert carbon dioxide to carbon monoxide, a useful starting material for synthesizing fuels. The… read more
An international team has demonstrated a form of quantum cryptography that can protect people doing business with others they may not know or trust – a situation encountered often on the Internet and in everyday life — for example, at a bank’s ATM.
“I expect that quantum technologies will gradually become integrated with existing devices such as smartphones, allowing us to do things like identify ourselves securely or generate… read more

“Coherent photon conversion” could potentially overcome the unresolved problems for optical implementations of quantum computing. An international team of scientists led by researchers from the Vienna Center for Quantum Science and Technology (VCQ) at the University of Vienna (group of Anton Zeilinger) introduced this new scheme this week in Nature.
The new scheme provides a method of coherent conversion between different photon states and is… read more

Blekko, a search engine that will open to the public on Monday, aims to show search results from only useful, trustworthy sites.
Blekko’s search engine scours three billion Web pages that it considers worthwhile, but it shows only the top results on any given topic. It calls its edited lists of Web sites slashtags. The engine also tries to weed out Web pages created by … read more
MIT and Harvard University researchers have found a two-dimensional material whose properties are very similar to graphene*, but with some distinct advantages — including the fact that this material naturally has a usable bandgap, which is essential for making devices such as computer chips and solar cells.
The new material, is a combination of nickel and an organic compound called HITP. Its constituents also naturally… read more

Scientists at Karlsruhe Institute of Technology (KIT) and Evonik Industries have developed a self-healing chemistry that allows for rapid healing of a plastic material using mild heating, restoring its initial molecular structure. It is based on a reversible chemical crosslinking reaction*.
- The reaction happens at temperatures from 50°C (122°F) to 120°C (248°F).
- The material can be restored completely in less than 5 minutes, and

Electrical engineers at Oregon State University have discovered a new method, called acoustic-assisted magnetic recording, to use high-frequency sound waves to create durable solid state storage that allows for storing more data in a smaller space, using less power.

Scientists have long observed that species seem to have become increasingly capable of evolving in response to changes in the environment.
But computer science researchers now say that the popular explanation of competition to survive in nature may not actually be necessary for evolvability to increase.
A study by UT Southwestern Medical Center researchers reveals new insight into why the most common, deadly kind of brain tumor in adults recurs and identifies a potential target for future therapies.
Glioblastoma multiforme (GBM) currently is considered incurable. Despite responding to initial therapy, the cancer almost always returns.
GBM is a fast-growing, malignant brain tumor that occurred in 15 percent of the… read more

A new tool that could help map and track the interactions between neurons in different areas of the brain is being developed by University of Texas Arlington assistant professor of physics Samarendra Mohanty.
The technology would be useful in the BRAIN (Brain Research Through Advancing Innovative Neurotechnologies) mapping initiative.

A new solid state NMR method that uses paramagnetic tags to help visualize the shape of protein molecules has been developed by Christopher Jaroniec, associate professor of chemistry at Ohio State University, and colleagues.
The new method could help researchers understand biological molecules involved in causing disease and those performing critical functions in healthy cells.
For roughly a decade, a technique called solid state nuclear magnetic resonance… read more

A drug commonly used to treat arthritis caused a dramatic and rapid improvement in patients with Alzheimer’s disease, according to physicians in California. However, scientists and others not involved in the work worry that the report, which was based on trials in a few patients and hasn’t been independently confirmed, may offer little more than false hope for Alzheimer’s sufferers and their families.
