A new study by a team of researchers has found that the consolidation of traditional smallholder farms in China has a devastating effect on the biodiversity of wild pollinators in the area.
A team of chemists from the Croatian Ruđer Bošković Institute (RBI) described a new, easy-to-use method for uninterrupted monitoring of mechanochemical reactions. These reactions are conducted in closed milling devices, so in order to monitor the reaction one has to open the reaction vessel, thus interfering with the process. The new method uses Raman spectroscopy to get deeper insight into solid-state milling reactions, without the usual interruption of the chemical reaction process.
On 23 July 2012, humanity escaped technological and economic disaster. A diffuse cloud of magnetized plasma in the shape of a slinky toy tens of thousands of kilometers across was hurled from the Sun at a speed of hundreds of kilometers per second.
Interstellar clouds are the birthplaces of new stars, but they also play an important role in the origins of life in the Universe through regions of dust and gas in which chemical compounds form. The research group, molecular systems, led by ERC prize winner Roland Wester at the Institute for ion physics and applied physics at the University of Innsbruck, has set itself the task of better understanding the development of elementary molecules in space. "Put simply, our ion trap allows us to recreate the conditions in space in our laboratory," explains Roland Wester.
With the looming threat of climate change, it is high time we embrace renewable energy sources on a larger scale. Photovoltaic systems, which generate electricity from the nearly limitless supply of sunlight energy, are one of the most promising ways of generating clean energy. However, integrating photovoltaic systems into existing power grids is not a straightforward process.
When it comes to improving access to mental health services for children and families in low-income communities, a University of Houston researcher found having a warm handoff, which is a transfer of care between a primary care physician and mental health provider, will help build trust with the patient and lead to successful outcomes.
Irvine, CA - July 20, 2021 - In a new University of California, Irvine-led study, researchers found that a certain protein prevented regulatory T cells (Tregs) from effectively doing their job in controlling the damaging effects of inflammation in a model of multiple sclerosis (MS), a devastating autoimmune disease of the nervous system.
Published this month in Science Advances, the new study illuminates the important role of Piezo1, a specialized protein called an ion channel, in immunity and T cell function related to autoimmune neuroinflammatory disorders.
Ten years after one of the largest nuclear accidents in history spewed radioactive contamination over the landscape in Fukushima, Japan, a University of Georgia study has shown that radioactive contamination in the Fukushima Exclusion Zone can be measured through its resident snakes.
The team's findings, published in the recent journal of Ichthyology & Herpetology, report that rat snakes are an effective bioindicator of residual radioactivity. Like canaries in a coal mine, bioindicators are organisms that can signal an ecosystem's health.
A recent study led by Geoff Burns, an elite runner and postdoctoral researcher at the University of Michigan Exercise & Sport Science Initiative, compared the "bouncing behavior"--the underlying spring-like physics of running--in elite-level male runners (sub-four-minute milers) vs. highly trained but not elite runners.
TUCSON, Ariz., July 20, 2021 — The use of digital health technologies across health care and drug development has accelerated. A new paper titled “Digital Progression Biomarkers as Novel Endpoints in Clinical Trials: A Multistakeholder Perspective,” co-authored by experts across diverse disciplines, highlights how new remote monitoring technologies present a tremendous opportunity to advance digital medicine in health care even further, specifically in Parkinson’s disease.
Researchers revealed new insights into how acute myeloid leukemia (AML) develops and progresses, according to a study published in Molecular Cell on July 20, 2021. They describe a mechanism by which AML cells regulate a cancer-related protein, mutant IDH2, to increase the buildup of blood cancer cells--a distinguishing characteristic of the disease.
For children with Type 1 diabetes, the risk of experiencing a severe hypoglycemic episode is especially common -- and for parents, the threat of that happening in the middle of the night is especially frightening. Sudden and critical drops in blood sugar can go undetected overnight when the child is asleep, resulting in coma and death -- an event known as "dead in bed syndrome."
Hamilton, ON (July 19, 2021) - A potentially game-changing treatment for people with, or at risk of, blood clots has been found effective by an international team of researchers led by McMaster University's Jeffrey Weitz.
Weitz's team compared abelacimab with enoxaparin as a control drug in 412 patients undergoing knee replacement surgery. Results showed that just one abelacimab injection prevents blood clots for up to a month after surgery, reducing the risk by about 80% compared with enoxaparin without increasing the risk of bleeding.
What The Study Did: Researchers examined racial/ethnic disparities in outpatient visit rates to 29 physician specialties in the United States.
