Neuroscientists Isolate Chills at a Cellular Level, Turn Off the Ability to Feel Cold

Scientists Turn Off the Ability to Feel Cold

Neuroscientists at USC have isolated and ablated the neurons that express TRPM8, finding that mice depleted of TRPM8 neurons could not feel cold but still responded to heat. USC researchers have isolated chills at a cellular level, identifying the sensory network of neurons in the skin that relays the sensation of cold. David McKemy, associate […]

MOF Powered by Sunlight Could Help Drastically Cut Carbon Emissions

Carbon Sponge Could Soak Up Coal Emissions

Researchers from Monash University and CSIRO have discovered a photosensitive metal organic framework (MOF) that utilizes sunlight to release large amounts of stored carbon. Emissions from coal power stations could be drastically reduced by a new, energy-efficient material that adsorbs large amounts of carbon dioxide, then releases it when exposed to sunlight. In a study […]

DARPA Focuses on Behavioral Biometrics to Enhance Cyber Security

Behavioral Biometrics for Mobile Devices

DARPA’s Active Authentication program is working to develop behavioral biometrics focused on the user’s cognitive processes to enhance cyber security. In the world of network cyber security, the weak link is often not the hardware or the software, but the user. Passwords are often easily guessed or possibly written down, leaving entire networks vulnerable to […]

Scientists Reconstruct the Ancestor of Placental Mammals

Ancestor of Placental Mammals

More than twenty scientists collaborated on a recently published study that reconstructed the ancestor of placental mammals. The common ancestor of more than 5,000 contemporary placental mammals such as rats, whales, and humans was a small, insect-eating animal that appeared after the dinosaurs went extinct 65 million years ago, an international team of researchers report […]

Natural Toxins Combined with Synthetic Drugs Could Disarm Cancer, Drug-Resistant Bacteria

Natural Toxins Could Disarm Cancer and Drug Resistant Bacteria

Researchers at Rice University believe that combining natural toxins with man-made mirror drugs will create the drug equivalent of a one-two punch, “confusing” bacteria and cancer and preventing them from rapidly becoming resistant to the man-made drugs. Cancer researchers from Rice University suggest that a new man-made drug that’s already proven effective at killing cancer […]

Researchers Identify a Protein that Blocks HIV

25HC Suppresses HIV Growth

In a newly published study, scientists have shown that an oxysterol called 25-hydroxycholesterol (25HC) suppresses HIV growth in vivo. A team of UCLA-led researchers has identified a protein with broad virus-fighting properties that potentially could be used as a weapon against deadly human pathogenic viruses such as HIV, Ebola, Rift Valley Fever, Nipah and others […]

Copper Sulfide Could Enable Faster Memory Chips and More Efficient Batteries

Cooper Sulfide Could Enable Faster Memory Chips

A new study from SLAC and Stanford researchers examines the atomic-scale details of how superionic nanoscale materials switch from a state that is poorly conducting to one that is highly conducting, taking a step forward toward using these materials in low-cost solid-state electrical batteries. A material that could enable faster memory chips and more efficient […]
