Artificial light at night (ALAN) is a major factor in global insect decline. In a paper published today in Insect Conservation and Diversity, Smithsonian Conservation Biology Institute (SCBI) scientists and partners found that using amber-colored filters to remove the blue spectra of light from "warm white" LED (light-emitting diode) lamps drastically reduces insect attraction to nocturnal lighting in a tropical forest.
BOSTON - There are several effective interventions to reduce the risk of suicide, the tenth-leading cause of death in the United States, but difficulties in identifying people at risk for suicide and concerns about the potentially high costs of suicide-prevention strategies have hampered their wider use.
But as researchers at Massachusetts General Hospital (MGH) demonstrate, statistical suicide risk prevention models could be implemented cost-effectively in U.S. health care systems and might help save many lives each year.
Combining tissue engineering and regenerative medicine, scientists have fabricated a series of heart valve replacements with the ability to incorporate host cells, enabling them to regenerate and grow over time. The valves expanded and maintained their function for a year when implanted into growing lambs, suggesting they could address the dire need for a long-term valve replacement for children with congenital heart disorders.
ITHACA, N.Y. - If you want to build a fully functional nanosized robot, you need to incorporate a host of capabilities, from complicated electronic circuits and photovoltaics to sensors and antennas.
But just as importantly, if you want your robot to move, you need it to be able to bend.
Many people have never heard of Brucellosis, but farmers and ranchers in the United States forced to cull animals that test positive for the disease and people infected by the animal-transmitted Brucella abortus (B. abortus) pathogen that suffer chronic, Malaria-type symptoms, certainly have.
Scientists at the U.S. Department of Energy's Ames Laboratory and their partners from Clemson University have discovered a green, low-energy process to break down polystyrene, a type of plastic that is widely used in foam packaging materials, disposable food containers, cutlery, and many other applications.
BIRMINGHAM, Ala. - The triggers and causes of a severe scarring disease of the lungs -- idiopathic pulmonary fibrosis, or IPF -- remain unclear.
Now research published in Science Translational Medicine shows how cadmium and carbon black can trigger lung macrophages to produce a modified protein, citrullinated vimentin, or cit vim, which leads to lung fibrosis. Researchers from the University of Alabama at Birmingham and three other American universities also describe a sequence of mechanistic steps in lung macrophages and lung fibroblasts that leads to the lung scarring.
A radio telescope located in outback Western Australia has observed a cosmic phenomenon with a striking resemblance to a jellyfish.
Published today in The Astrophysical Journal, an Australian-Italian team used the Murchison Widefield Array (MWA) telescope to observe a cluster of galaxies known as Abell 2877.
WASHINGTON--People who start eating before 8:30 a.m. had lower blood sugar levels and less insulin resistance, which could reduce the risk of developing type 2 diabetes, according to a study presented virtually at ENDO 2021, the Endocrine Society's annual meeting.
A large gathering of fish tempts harbour porpoises to search for food around oil and gas platforms, even though the noise from these industrial plants normally to scare the whales away. Decommissioned platforms may therefore serve as artificial reefs in the North Sea.
A joint research team, affiliated with UNIST has unveiled a novel electrolyte additive that could enable a long lifespan and fast chargeability of high-energy-density lithium-ion batteries (LIBs).
A study from Chalmers University of Technology, Sweden, has yielded new answers to fundamental questions about the relationship between the size of an atom and its other properties, such as electronegativity and energy. The results pave the way for advances in future material development. For the first time, it is now possible under certain conditions to devise exact equations for such relationships.
Mass movements such as landslides and hill-slope debris flows cause billions of euros in economic damage around the world every year. Between 20 and 80 million euros are spent annually from the disaster fund to repair disaster damage in Austria, 15 to 50 percent of which is attributable to mud flows and landslides. Now, a team of geologists from Graz University of Technology (TU Graz), in cooperation with the Burgenland state road administration, identified for the first time the chemical influencing factors and triggers for recurrent mass movements in fine-grained sediments.
Lenexa, Kan. -- The Infusion Nurses Society has expanded its guidance on the use of needleless connectors to include anti-reflux technology in its recently published 2021 Infusion Therapy Standards of Practice, according to Nexus Medical, makers of the Nexus TKO®-6P Anti-Reflux connector.
March 18, 2021 -- A study conducted at Columbia University Mailman School of Public Health reports a high global prevalence of both depression and anxiety during the COVID-19 pandemic and shows how implementation of mitigation strategies including public transportation and school closures, and stay-at-home orders impacted such disorders. The results are published in Psychological Medicine.
