Himalayan wolf discovered to be a unique wolf adapted to harsh high altitude life — ScienceDaily

The Himalayan wolf is considered an ancient wolf as it evolved prior to the contemporary grey wolf which is found in large parts of North America and Eurasia. Very little is known about the Himalayan wolf, because science and conservation have overlooked these high-altitude wolves as just another grey wolf until recently. As a result, very little research had been conducted on this wolf and no conservation action has been

Tiny, battery-free ID chip can authenticate nearly any product to help combat losses to counterfeiting — ScienceDaily

To combat supply chain counterfeiting, which can cost companies billions of dollars annually, MIT researchers have invented a cryptographic ID tag that's small enough to fit on virtually any product and verify its authenticity. A 2018 report from the Organization for Economic Co-operation and Development estimates about $2 trillion worth of counterfeit goods will be sold worldwide in 2020. That's bad news for consumers and companies that order parts from

Therapeutic cooling effectively targets site of brain injury — ScienceDaily

When a newborn suffers lack of oxygen before or during birth, doctors have very little time to save precious brain tissue. The only proven effective way to treat babies with hypoxic brain injuries is by reducing body temperature through controlled cooling. In a new study, Children's Hospital Los Angeles neonatologist Tai-Wei Wu, MD, uses leading-edge imaging to measure temperature deep in the brains of these patients. The results demonstrate effective

Methane emitted by humans vastly underestimated — ScienceDaily

Methane is a powerful greenhouse gas and large contributor to global warming. Methane emissions to the atmosphere have increased by approximately 150 percent over the past three centuries, but it has been difficult for researchers to determine exactly where these emissions originate; heat-trapping gases like methane can be emitted naturally, as well as from human activity. University of Rochester researchers Benjamin Hmiel, a postdoctoral associate in the lab of Vasilii

Research team tackles superbug infections with novel therapy — ScienceDaily

There may be a solution on the horizon to combating superbug infections resistant to antibiotics. The tenacious bacteria and fungi sicken more than 2.8 million people and lead to more than 35,000 deaths in the United States each year. An international team of researchers has found that a combination of ingredients (acidified nitrite and ethylenediaminetetraacetic acid) known as AB569 and developed by a University of Cincinnati scientist kills a bacteria

Scientists solve long-debated puzzle of how the intestine heals itself — ScienceDaily

Deep within the lining of the human intestine lies the source of the organ's ability to renew itself and recover from damage: intestinal stem cells (ISCs), lodged in pockets of tissue called crypts, generate the cells that continuously repopulate the intestinal lining. Even the stem cells themselves have a safety net: when they're damaged, healthy replacements appear in less than a week. For years, scientists have debated how the ISCs'

New drug helps to preserve brain cells for a time after stroke — ScienceDaily

After 50 years of research and the testing of over 1,000 drugs, there is new hope for preserving brain cells for a time after stroke. Treating acute ischemic stroke patients with an experimental neuroprotective drug, combined with a surgical procedure to remove the clot improves outcomes as shown by clinical trial results published today in The Lancet. The multi-centre, double-blinded, randomized trial, led by a team at the Cumming School

New study describes science behind best lights to affect sleep, mood and learning — ScienceDaily

Researchers said the wavelengths at sunrise and sunset have the biggest impact to brain centers that regulate our circadian clock and our mood and alertness. Their study, "A color vision circuit for non-image-forming vision in the primate retina," published in Current Biology Feb. 20, identifies a cell in the retina, which plays an important role in signaling our brain centers that regulate circadian rhythms, boost alertness, help memory and cognitive

A deep-learning model identifies a powerful new drug that can kill many species of antibiotic-resistant bacteria — ScienceDaily

Using a machine-learning algorithm, MIT researchers have identified a powerful new antibiotic compound. In laboratory tests, the drug killed many of the world's most problematic disease-causing bacteria, including some strains that are resistant to all known antibiotics. It also cleared infections in two different mouse models. The computer model, which can screen more than a hundred million chemical compounds in a matter of days, is designed to pick out potential
