When Hurricane Irma made landfall in Florida in September 2017, the Category 5 storm offered a team of wildlife researchers a first-ever opportunity to observe behavioral responses of white-tailed deer to an extreme weather event in real time. The data collected are providing crucial new insights for scientists seeking to minimize the impacts of severe weather and climate change on wildlife.
Cross-linked polymers are structures where large molecular chains are linked together, allowing exceptional mechanical properties and chemical resistance to the final product. However, their modification is not easy. Now, scientists at Tokyo Institute of Technology develop a method that allows the fusion of different polymers together easily, allowing the precise tuning of the properties of the final material by selecting appropriate base polymers and mixing them at the right proportion.
Promotional vaping Instagram posts outnumber anti-vaping content 10,000 to 1, according to a new study published in Frontiers in Communication.
In the Pacific Northwest, the range expansion of Barred Owls has contributed to a conservation crisis for Northern Spotted Owls, which are being displaced from their old-growth forest habitat. How will this interaction between species play out in the Sierra Nevada, where Barred Owls are just starting to move into the range of the California Spotted Owl? New research published in The Condor: Ornithological Applications suggests that wildlife managers may still be able to head off similar problems in critical areas of the Golden State -- if they act now.
Mathematicians, physicists, and materials experts might not spring to mind as the first people to consult about whether you are brewing your coffee right. But a team of such researchers from around the globe--the United States, the United Kingdom, Ireland, Australia, and Switzerland--are challenging common espresso wisdom, finding that fewer coffee beans, ground more coarsely, are the key to a drink that is cheaper to make, more consistent from shot to shot, and just as strong. Their work appears January 22 in the journal Matter.
Washington, DC - January 22, 2020 - Candida auris is capable of forming high burden biofilms, which may help explain why this fungal pathogen is spreading in hospitals worldwide, according to a study published this week in mSphere, an open-access journal of the American Society for Microbiology. The research also establishes a new model to investigate the spread of this emerging fungal pathogen that causes invasive infections and is an emerging problem in hospitals worldwide.
It's a leading research strategy for eliminating HIV from the body: "shock and kill." The idea is to activate the dormant virus from within the immune cells where it hides, then eliminate it. One obstacle has been finding a safe way to wake up the virus.
In two complementary Nature papers, researchers now report that they have come closer to that goal. The papers are from researchers at the Yerkes National Primate Research Center of Emory University and the University of North Carolina at Chapel Hill, funded by the National Institutes of Health.
When Marie Antoinette was captured during the French Revolution, her hair reportedly turned white overnight. In more recent history, John McCain experienced severe injuries as a prisoner of war during the Vietnam War -- and lost color in his hair.
Researchers have found how an antibiotic used to treat a debilitating gut infection stays put inside the body giving it time to effectively treat the problem, a discovery that will pave the way for the development of more effective antibiotic treatments to fight superbugs.
PE (pseudomembranous colitis) is a debilitating inflammation of the colon caused by infection with the microbe Clostridium difficile (and sometimes Staphylococcus aureus). The sugar- or carbohydrate-containing antibiotic known as vancomycin is taken by mouth to kill the infecting microbe.
EUGENE, Ore. - Jan. 22, 2020 - Espresso delivers a desired jolt of caffeine but getting a consistent good-taste is difficult. New research is offering a roadmap to reproducibility and a potential savings of $3.1 million a day for coffee shops across the United States.
In a new study, now online ahead of print in the journal Matter, a 10-member international team of researchers performed mathematical modeling and brewed hundreds of espresso shots to discover the key variables required to make consistently tasty coffee.
NMDARs (N-methyl-D-aspartate receptors) serve as valves on nerve cells, controlling the flow of electrical signals in the brain. This special group of receptors is suspect in many neurological diseases, including Alzheimer's, epilepsy, stroke, and Parkinson's. Biologists from Cold Spring Harbor Laboratory (CSHL) and chemists from the University of Bristol have joined forces, creating a chemical compound to enable more precise investigation of NMDAR activity.
A new study from researchers at Columbia University Vagelos College of Physicians and Surgeons found that non-medical cannabis use--including frequent or problematic use--is significantly more common in adults with pain than in those without pain.
The findings were published in the American Journal of Psychiatry.
Since 1996, 34 states have passed medical marijuana laws and 11 states have legalized recreational cannabis use.
Mathematicians, physicists and materials experts might not spring to mind as the first people to consult about whether you are brewing your coffee right.
But a team of such researchers including Dr Jamie Foster, a mathematician at the University of Portsmouth, are challenging common espresso wisdom.
They have found, that fewer coffee beans, ground more coarsely, are the key to a drink that is cheaper to make, more consistent from shot to shot, and just as strong.
The study is published in the journal Matter.
CHAPEL HILL, NC - January 22, 2020 - Approximately 38 million people are infected with HIV worldwide, about 1.1 million people in the United States. Currently, people with HIV take antiretroviral therapy (ART), which can suppress HIV to undetectable levels in blood, but the virus persists throughout the body in latently infected resting CD4+ T cells. The immune system cannot recognize these cells and no current therapies can eliminate them. When ART is stopped, viral loads spike in blood.
