Biomedical scientists working with COVID-19 have a new tool to help them better understand the virus and feel confident about the structural models they are using in their research.
Middle-aged and older adults who identify as lesbian, gay, or bisexual have higher rates of using certain substances in the past year than those who identify as heterosexual, according to a new study led by researchers at NYU Grossman School of Medicine and the Center for Drug Use and HIV/HCV Research (CDUHR) at NYU School of Global Public Health. The study is published in the Journal of General Internal Medicine.
The United States Army Research Laboratory is lending support to a Texas A&M University research project investigating potential improvement of ballistic performance of armor materials.
The project, led by Dr. Justin Wilkerson, assistant professor and James J. Cain '51 Faculty Fellow II in the J. Mike Walker '66 Department of Mechanical Engineering, focuses on identifying what damaging effects could be caused by particular flaws -- known as vacancies -- in the atomic structure of aluminum.
Colorado State University Distinguished Professor Sonia Kreidenweis and her research group identified an atmospheric region unchanged by human-related activities in the first study to measure bioaerosol composition of the Southern Ocean south of 40 degrees south latitude.
Researchers at the Francis Crick Institute, the Institut Pasteur and their clinical collaborators have identified a cause of testicular tissue developing in people with female chromosomes.
"Differences in sexual development" (DSD) are genetic conditions in which there is a mismatch between the chromosomal sex, XY or XX, which are typically of males and females, and some aspect of their anatomy, for example, an XY individual born as female or XX individual born as male. In many of the cases the genetic cause is unknown. The prevalence is 1 in 2,500-4,000 individuals.
A team led by researchers at Carnegie Mellon University has created a new technology that enhances scientists' ability to communicate with neural cells using light. Tzahi Cohen-Karni, associate professor of biomedical engineering and materials science and engineering, led a team that synthesized three-dimensional fuzzy graphene on a nanowire template to create a superior material for photothermally stimulating cells.
The notion of conserving climate change refugia - areas relatively buffered from current climate change that shelter valued wildlife, ecosystems, and other natural resources - is only about 10 years old, but the field has matured enough that a leading journal has prepared a special issue on the topic.
Boulder, Colo., USA: A common message in use to convey the seriousness of climate change to the public is: "Carbon dioxide levels are higher today than they have been for the past one million years!" This new study by Brian Schubert (University of Louisiana at Lafayette) and coauthors Ying Cui and A. Hope Jahren used a novel method to conclude that today's carbon dioxide (CO2) levels are actually higher than they have been for the past 23 million years.
NEW YORK, NY (June 1, 2020) - A new study published today in Neuron led by The New York Stem Cell Foundation (NYSCF) Research Institute's Valentina Fossati, PhD, creates astrocytes - an integral support cell in the brain - from stem cells and shows that in disease-like environments, these normally helpful cells can turn into neuron-killers.
Rockville, MD (June 1, 2020) - Warning labels on sugary drinks lead to healthier drink choices, according to new analysis of more than 20 studies examining these warnings. The new findings could help inform policymakers, who are increasingly interested in implementing policies requiring warning labels for sugar-sweetened beverages. Sugary drinks (also known as sugar sweetened beverages) refer to beverages with added sugar or other sweeteners, such as soda, sports drinks or fruit-flavored drinks.
Many of us are eating differently during the COVID-19 pandemic, and some are taking the stay-at-home lifestyle as an opportunity to work on weight loss goals. Get the latest research findings on fad diets, losing weight and healthful eating at NUTRITION 2020 LIVE ONLINE, a virtual conference featuring leading nutrition experts from around the world.
Professor Fabien Sorin and doctoral assistant Andreas Leber, at the Laboratory of Photonic Materials and Fibre Devices (FIMAP) in EPFL's School of Engineering, have developed a technology that can be used to detect a body's movements - and a whole lot more. "Imagine clothing or hospital bed sheets capable of monitoring your breathing and physical gestures, or AI-powered textiles that allow humans to interact more safely and intuitively with robots" says Leber. "The flexible transmission lines that we've developed can do all of this."

The 26th Conference of the Parties (COP26) to the UN Framework Convention on Climate Change (UNFCCC) was scheduled to be held in Glasgow, Scotland in November 2020, and was expected to gather thousands of negotiators, policymakers, researchers, journalists and campaigners.
Due to the COVID-19 pandemic, Parties decided to postpone this big event, instead of moving it online as they did with smaller meetings in the past months. As announced a few days ago, COP26 will now take place between 1 and 12 November 2021 in Glasgow.
Durham, NC - The gene p53 is extremely important in cell biology and, hence, the world of cell replacement therapy. Its role is to regulate the cell cycle and halt the formation of tumors, leading to its nickname the "tumor suppressor gene." However, previous efforts to determine whether p53 is behind programmed cellular death (apoptosis) induced by DNA damage in pluripotent embryonic stem cells (ESCs) produced conflicting results. Initial studies said that it was not; later studies concluded that it was.
Professor Fabien Sorin and doctoral assistant Andreas Leber, at the Laboratory of Photonic Materials and Fibre Devices (FIMAP) in EPFL's School of Engineering, have developed a technology that can be used to detect a body's movements - and a whole lot more. "Imagine clothing or hospital bed sheets capable of monitoring your breathing and other vital movements, or AI-powered textiles that allow robots to interact more safely and intuitively with humans" says Leber. "The soft transmission lines that we've developed open the door to all of this."
