HOUSTON - (April 30, 2021) - The microscopic structures and properties of materials are intimately linked, and customizing them is a challenge. Rice University engineers are determined to simplify the process through machine learning.
To that end, the Rice lab of materials scientist Ming Tang, in collaboration with physicist Fei Zhou at Lawrence Livermore National Laboratory, introduced a technique to predict the evolution of microstructures -- structural features between 10 nanometers and 100 microns -- in materials.
CHARLOTTESVILLE, Va. - In 2018, industry and academic researchers revealed a potentially devastating hardware flaw that made computers and other devices worldwide vulnerable to attack.
The marine worm Ramisyllis multicaudata, which lives within the internal canals of a sponge, is one of only two such species possessing a branching body, with one head and multiple posterior ends. An international research team led by the Universities of Göttingen and Madrid is the first to describe the internal anatomy of this intriguing animal. The researchers discovered that the complex body of this worm spreads extensively in the canals of their host sponges.
A study led by The Ohio State University College of Nursing finds that critical care nurses in poor physical and mental health reported significantly more medical errors than nurses in better health.
The study, which was conducted before the COVID-19 pandemic, also found that "nurses who perceived that their worksite was very supportive of their well-being were twice as likely to have better physical health."
Boston, MA (May 1, 2021) - Preliminary results of a clinical trial, presented today at the AATS 101st Annual Meeting, showed that a new, low-profile thoracic aortic endograft is safe and effective in the treatment of descending thoracic aortic aneurysm or penetrating atherosclerotic ulcer (PAU) diseases. A multi-disciplinary team, led by both cardiac and vascular surgeons as co-investigators, conducted the study in 36 centers in the United States and Japan, enrolling patients between 2016 and 2019.
Niigata, Japan - Researchers from Niigata University , the University of Tokyo, Osaka University and Tokyo Medical University, Japan have developed a new approach that could revolutionize the treatment, prevention, and possibly reversal of the damages caused by liver diseases. This novel strategy exploits small extracellular vesicles (sEVs) derived from interferon-γ (IFN-γ) pre-conditioned MSCs (γ-sEVs).
As the health of ecosystems in regions around the globe declines due to a variety of rising threats, scientists continue to seek clues to help prevent future collapses.
A new analysis by scientists from around the world, led by a researcher at the University of California San Diego, is furthering science's understanding of species interactions and how diversity contributes to the preservation of ecosystem health.
Researchers have developed a brain-like computing device that is capable of learning by association.
Similar to how famed physiologist Ivan Pavlov conditioned dogs to associate a bell with food, researchers at Northwestern University and the University of Hong Kong successfully conditioned their circuit to associate light with pressure.
The research will be published April 30 in the journal Nature Communications.
Targeting a pathway that is essential for the survival of certain types of acute myeloid leukaemia could provide a new therapy avenue for patients, the latest research has found.
Researchers from the Wellcome Sanger Institute found that a specific genetic mutation, which is linked with poor prognosis in blood cancer, is involved in the development of the disease when combined with other mutations in mice and human cell lines.
The future of particle acceleration has begun. Awake is a promising concept for a completely new method with which particles can be accelerated even over short distances. The basis for this is a plasma wave that accelerates electrons and thus brings them to high energies. A team led by the Max Planck Institute for Physics now reports a breakthrough in this context. For the first time, they were able to precisely time the production of the proton microbunches that drive the wave in the plasma.
New research indicates that the computer-based models currently used to simulate how Earth's climate will change in the future underestimate the impact that forest fires and drying climate are having on the world's northernmost forests, which make up the largest forest biome on the planet. It's an important understanding because these northern forests absorb a significant amount of Earth's carbon dioxide.
The proliferation of electric cars, smartphones, and portable devices is leading to an estimated 25 percent increase globally in the manufacturing of rechargeable batteries each year. Many raw materials used in the batteries, such as cobalt, may soon be in short supply. The European Commission is preparing a new battery decree, which would require the recycling of 95 percent of the cobalt in batteries. Yet existing battery recycling methods are far from perfect.
Older people with vision loss are significantly more likely to suffer mild cognitive impairment, which can be a precursor to dementia, according to a new study published in the journal Ageing Clinical and Experimental Research.
The research by Anglia Ruskin University (ARU) examined World Health Organisation data on more than 32,000 people and found that people with loss in both near and far vision were 1.7 times more likely to suffer from mild cognitive impairment.
Washington, D.C., April 29, 2021 - Two studies related to percutaneous coronary intervention (PCI) evaluating the use of risk-avoidance strategies and robotic-assisted technology, respectively, are being presented as late-breaking clinical science at the Society for Cardiovascular Angiography & Interventions (SCAI) 2021 Scientific Sessions. An analysis of strategically avoiding high-risk PCI cases indicates systematic risk-avoidance does not improve, and may worsen, the quality of hospital PCI programs.
The SARS-CoV-2 virus is still causing a dramatic loss of human lives worldwide, constituting an unprecedented challenge for society, public health, and economy, to overcome. Currently, SARS-CoV-2 can be diagnosed in two different ways: i) antigen tests (point-of-care, POC) and ii) molecular tests (nucleic acid, RNA, or PCR-polymerase chain reaction). Antigen tests can detect parts of SARS-CoV-2 proteins, known as antigens, via a nasopharyngeal or nasal swab sampling method.
