Through the investigation of insect surfaces, Penn State researchers have detailed a previously unidentified nanostructure that can be used to engineer stronger, more resilient water repellent coatings.
The results of this research were published today (July 17) in Science Advances.
With an enhanced ability to repel droplets, this design could be applied to personal protective equipment (PPE) to better resist virus-laden particles, such as COVID-19, among other applications.
While their ranks in academic surgery may be not be robust, women surgeons are holding their own when it comes to surgical research, securing a greater percentage of National Institutes of Health (NIH) grants than their numbers suggest.
Researchers from the Moscow Institute of Physics and Technology and their colleagues from Shemyakin-Ovchinnikov Institute of Bioorganic Chemistry and Prokhorov General Physics Institute of the Russian Academy of Sciences have developed a breakthrough technology to resolve a key problem that has prevented the introduction of novel drugs into clinical practice for decades. The new solution prolongs blood circulation for virtually any nanomedicine, boosting its therapeutic efficiency.
VENICE - From the moment a kidney becomes available, there are just 24 hours to identify the recipient and carry out the transplant. Waiting lists are extremely long, available organs are few and not all of them are 'ideal'. Furthermore, a recipient has the ability to 'refuse' a kidney, for instance by continuing with the dialysis treatment while waiting for a better moment, thus complicating the race against time to carry out the transplant.
By applying a machine-learning algorithm, scientists at the Niels Bohr Institute, University of Copenhagen, have developed a method to classify all gamma-ray bursts (GRBs), rapid highly energetic explosions in distant galaxies, without needing to find an afterglow - by which GRBs are presently categorized. This breakthrough, initiated by first-year B.Sc. students, may prove key in finally discovering the origins of these mysterious bursts. The result is now published in Astrophysical Journal Letters.
Experiences of discrimination over a lifetime is associated with high blood pressure in African American adults, according to findings published this month in the journal Hypertension from researchers at the Urban Health Collaborative at Drexel University's Dornsife School of Public Health.
CHAMPAIGN, Ill. -- There's a reason why people often forget to take a daily medication or respond to that email they've been meaning to send, and it can be chalked up to the gulf between intention and actually completing an action, according to new research co-written by a University of Illinois at Urbana-Champaign expert who studies social psychology.
First spotted in the United States in 2014, bacterial leaf streak of corn is an emerging disease of corn that has now spread to ten states, including the top three corn-producing states of Illinois, Iowa, and Nebraska.
New research by Welsh academics shows that a patient's pupils can reveal if they have suffered a traumatic experience in the past.
Post-traumatic stress disorder can occur when a person has experienced a traumatic event such as a car crash, combat stress, or abuse. They can be left with a greater sensitivity, or hyperarousal, to everyday events and an inability to switch off and relax.
Researchers at The University of Texas Health Science Center at San Antonio (UT Health San Antonio) have discovered a new class of proteins that protect synapses from being destroyed. Synapses are the structures where electrical impulses pass from one neuron to another.
The discovery, published July 13 in the journal Nature Neuroscience, has implications for Alzheimer’s disease and schizophrenia. If proven, increasing the number of these protective proteins could be a novel therapy for the management of those diseases, researchers said.
EUGENE, Ore. - July 17, 2020 - Uplifting of Columbia River basalts has allowed University of Oregon researchers to better understand of how magma 14-16 million years ago shaped the region and why greenhouse gases released during a series of volcanic eruptions did not trigger a global extinction event.
The insights, published in Scientific Reports, were drawn from analyses of oxygen and hydrogen isotopes in crustal material, a mix of magma and original rocks, that is now exposed by geological uplifting and erosion.
Research by the University of Southampton shows European countries need to work together when lifting lockdown measures, to prevent COVID-19 cases rising again on the continent.
Researchers from Munich and Ulm have determined how the pandemic coronavirus SARS-CoV-2 inhibits the synthesis of proteins in infected cells and shown that it effectively disarms the body's innate immune system.
While early research on the adaptive immune response to COVID-19 primarily looked at antibodies, more information is now emerging on how T cells react to the SARS-CoV-2 virus - addressing a crucial knowledge gap, say Daniel Altmann and Rosemary Boyton in a new Perspective. While antibody responses are generally much easier to study, T cells are known to play a more important role in protecting the body against viral infections.
Coordinated lockdown strategies among countries is key to preventing resurgent COVID-19 outbreaks in continental Europe, a new modeling study shows. A continental epidemic could occur as many as five weeks earlier when well-connected countries with stringent existing interventions end their interventions prematurely, the study's authors say. As rates of new COVID-19 cases begin to decline in countries around the world, governments are considering how to ease restrictions without disease resurgence.
