Portable, injectable clotting agent could treat trauma victims on the front linesIn a hospital, internal bleeding can be controlled with the transfusion of clotting agents, such as platelets, but they require careful storage and refrigeration and can't be carried by first responders. Now, researchers report an injectable clotting agent that reduced blood loss by 97 percent in mice models. The freeze-dried agent, which has a physical consistency of cotton candy, can be stored...
Topical application of three-phage cocktail decreased the bacterial load of diabetic foot ulcer with efficacy similar or superior to vancomycin (Jul 2020, mice) Efficacy of phage cocktail AB-SA01 therapy in diabetic mouse wound infections caused by multidrug-resistant Staphylococcus aureusAustralian researchers have shown how viruses can be used to save lives, developing the potential use of bacteriophages in bandages to treat life-threatening golden staph infections which may not respond to traditional antibiotics. Targeting multidrug-resistant Staphylococcus aureus ('golden staph') in diabetic foot ulcers, Flinders University microbiology researchers have joined infectious...
Huntsman Cancer Institute illuminates potential new treatment in acute myeloid leukemiaIn a study published in the journal Leukemia, lead author Ami Patel, MD, Huntsman Cancer Institute researcher and assistant professor in the Division of Hematology and Hematologic Malignancies at the University of Utah, showed that factors produced by bone marrow support cells allowed leukemia cells to survive treatment with quizartinib, a type of TKI. When quizartinib was combined with another...
Gut feelings can be good for us - "Study finds association between feeling full and positive body image. New research has found that paying greater attention to internal bodily sensations can increase our appreciation of our own bodies."New research has found that paying greater attention to internal bodily sensations can increase our appreciation of our own bodies.
Physicists find misaligned carbon sheets yield unparalleled propertiesA material composed of two one-atom-thick layers of carbon has grabbed the attention of physicists worldwide for its intriguing -- and potentially exploitable -- conductive properties. University of Texas at Dallas physicists are studying how the ability of twisted bilayer graphene to conduct electrical current changes in response to mid-infrared light.1
Results from 27 countries suggest that, despite the risk of severe illness due to COVID-19, elderly people are not more willing to isolate when asked to, and aren't compliant with COVID-19 preventive measures. People aged 60 to 80 are also less likely than younger age groups to wear a mask outsideSurvey results from 27 countries suggest that, despite their increased risk of severe illness due to COVID-19, elderly people are not more willing to isolate when asked to, and are not more compliant with several COVID-19 preventive measures. Jean-François Daoust of the University of Edinburgh, UK, presents these findings in the open-access journal PLOS ONE on July 2, 2020.
A never-before-seen, highly plastic cell state may explain how cancer gains resistance to drugs. A few extremely malleable tumor cells are able to craft their epigenetic makeup to evade chemotherapy and produce new, resistant clones. Targeting this specific state may prolong treatment effectiveness.Scientists at the Sloan Kettering Institute, the Koch Institute at MIT, and the Klarman Cell Observatory at the Broad Institute have identified an unusual cell state that emerges early in tumor evolution and supports a cancer's ability to outwit chemotherapy.
Hedonism leads to happiness - "Relaxing on the sofa or savoring a delicious meal: Enjoying short-term pleasurable activities that don't lead to long-term goals contributes at least as much to a happy life as self-control, according to new research"Relaxing on the sofa or savoring a delicious meal: Enjoying short-term pleasurable activities that don't lead to long-term goals contributes at least as much to a happy life as self-control, according to new research from the University of Zurich and Radboud University in the Netherlands. The researchers therefore argue for a greater appreciation of hedonism in psychology.1
Tandem catalytic system efficiently converts carbon dioxide to methanolBoston College chemists have used a tandem catalytic system to efficiently convert carbon dioxide to methanol. By encapsulating multiple catalysts involved in the tandem process in nanoporous materials called metal-organic frameworks, the team reports achieving superior performance by eliminating catalyst incompatibility. The method could be applied to other tandem catalytic processes, allowing...3
The most important task for a PTSD service dog for veterans is disrupting anxietyScience has shown that service dogs can benefit some veterans with PTSD. But the exact role service dogs play in the day-to-day lives of veterans is less known. A recent study shows what trained tasks service dogs perform the most often and which ones are the most helpful to veterans with post-traumatic stress disorder. The study found that the task of disrupting episodes of anxiety ranked among...
Mindfulness training helps men manage anger. Before treatment, 85% of the men in the study beat, kicked or shook their girlfriend. After treatment, it dropped to 10%. The last few weeks have been particularly difficult for people living in a violent relationship.Before treatment, 85% of the men in the study beat, kicked or shook their girlfriend. After treatment, most of them had stopped being violent.
Ultracold mystery: SolvedLast December, Harvard researchers designed technology that could achieve the lowest temperature chemical reactions and then broke and formed the coldest bonds in the history of molecular coupling. Now, though reactions are considered too fast to measure, they determined the exact lifespan of their intermediate--the space between reactants and products--and solved the mystery of why some ultracold molecules simply disappear.1
Meditation linked to lower cardiovascular risk - "Survey data from more than 61,000 people points to heart benefits"Meditation was linked to lower cardiovascular risk in a large database study by Veterans Affairs researchers and colleagues. The team looked at data on more than 61,000 survey participants.1
Is what I see, what I imagine? Study finds neural overlap between vision and imagination. Researchers at the Medical University of South Carolina find link between mental imagery and vision using artificial intelligence and human brain studies.In Current Biology, Medical University of South Carolina researchers report the results of a study using artificial intelligence and human brain studies to compare brain areas involved in mental imagery and vision. Their findings suggest that mental imagery and vision are similar, but that low-level visual areas are activated in a less precise manner with mental imagery. This suggests that the...1
