As a physical quantity pressure is encountered in various fields: atmospheric pressure in meteorology, blood pressure in medicine, or even in everyday life with pressure cookers and vacuum-sealed foods. Pressure is defined as a force per unit area acting perpendicular to a surface of a solid, liquid, or gas. Depending on the direction in which the force acts within a closed system, very high pressure can lead to explosive reactions in extrem cases, while very low pressure in a closed system can cause the implosion of the system itself. Overpressure ...

A digital twin may sound like something out of a science fiction film, but Pitt engineers are developing new technology to make them a reality in our campus and beyond. Digital twins – a model that serves as a real-time computational counterpart – can be used to help simulate the effects of multiple types of conditions, such as weather, traffic, and even climate change. Still, life-cycle assessments (LCAs) of climate change’s effects on infrastructure are still a work-in-progress, leaving a need ...

In the future, quantum computers may be able to solve problems that are far too complex for today’s most powerful supercomputers. To realize this promise, quantum versions of error correction codes must be able to account for computational errors faster than they occur.  However, today’s quantum computers are not yet robust enough to realize such error correction at commercially relevant scales. On the way to overcoming this roadblock, MIT researchers demonstrated a novel superconducting qubit ...

A new injectable solution that self-assembles into a gel under the right conditions could help manage HIV unlike any currently available methods, researchers have found. The gel releases a steady dose of the anti-HIV drug lamivudine over six weeks, suggesting people living with HIV could have new therapy that doesn’t require a daily pill regimen to prevent AIDS. “The primary challenge in HIV treatment is the need for lifelong management of the virus, and one way to address this is to reduce dosing frequencies to help patients stick to medical regimens,” said Honggang Cui, a Johns Hopkins University chemical and biomolecular engineer ...

Study finds immune cells in older adults resemble those in newborns and children, but fall short in virus detection A world-first discovery has revealed special immune cells called ‘killer T cells’ in older adults, directed against influenza viruses, closely resemble those found in newborns and children, but struggle to recognise infected cells – a finding that unlocks the potential for the development of better vaccines and therapies tailored to different age groups. Killer T cells (also known as CD8+ T cells) play a critical role in the immune system by eliminating virus-infected cells. ...

Long COVID patients have clear differences in immune and hormone function from patients without the condition, according to a new study led by the Icahn School of Medicine at Mount Sinai and Yale School of Medicine. The research, published in the September 25 issue of Nature, is the first to show specific blood biomarkers that can accurately identify patients with long COVID. “These findings are important—they can inform more sensitive testing for long COVID patients and personalized treatments for long COVID that have, until now, not had a proven scientific rationale,” says Principal Investigator David Putrino, ...

Studies of a ‘future-proof’ vaccine candidate have shown that just one antigen can be modified to provide a broadly protective immune response in animals. The studies suggest that a single vaccine with combinations of these antigens – a substance that causes the immune system to produce antibodies against it – could protect against an even greater range of current and future coronaviruses. The vaccine antigen technology, developed by the University of Cambridge and spin-out DIOSynVax in early 2020, provided protection against all known variants of SARS-CoV-2 – the virus that causes COVID-19 – as well as other ...

About The Study: In this systematic review and meta-analysis of 10 studies, physical restraint was uncommon, occurring in less than 1% of encounters, but adult Black patients experienced a significantly higher risk of physical restraint in emergency department settings compared with other racial groups. Emergency departments should carefully consider, and take steps to address, how racism may affect disparate use of restraints among adult patients.  Authors: Vidya Eswaran, M.D., of the Baylor College of Medicine in Houston, is the corresponding author.

The international study, published in Nature Human Behaviour, analysed millions of tweets by members of Congress over the last decade. Its findings showed both Republican and Democratic politicians were increasingly sharing their beliefs and opinions as well as evidence-based information. But among Republicans, their expression of honestly-held beliefs and opinions was strongly linked to less trustworthy information sources. Lead author Jana Lasser, a postdoctoral research fellow in computational social science at Graz University of Technology (TU Graz), said: “We wanted to find out what reasons and social changes contribute to people sharing ...

A new study shows unprecedented heat is likely to lead to the next mass extinction since the dinosaurs died out, eliminating nearly all mammals in some 250 million years time. The research, published today in Nature Geoscience and led by the University of Bristol, presents the first-ever supercomputer climate models of the distant future and demonstrates how climate extremes will dramatically intensify when the world’s continents eventually merge to form one hot, dry and largely uninhabitable supercontinent. The ...

New research, reported in Nature Ecology & Evolution, (25 September 2023) has for the first time validated at scale, one of the theories that has underpinned ecology for over half a century. In doing so, the findings raise further questions about whether models should be revised to capture human impacts on natural systems. Scientists working in the 50’s and 60’s developed theories to predict the ecological distribution of species.  These theories could be applied across a broad range of environments and variables such as food supply or temperature and when tested on a small scale they were found to be accurate. Amongst the earliest examples of these ...

A new objective examination of almost a quarter-of-a-century of ocean acidification research shows that, despite challenges, experts in the field can have confidence in their research. The University of Adelaide’s Professor Sean Connell from the Ecology and Evolutionary Biology unit led the study. “In our field, the marine science community was galvanised by the demonstration of how ocean acidification impairs shell-building life, which has profound implications for life on the planet,” ...

OXFORD - 25/09/2023 - A new study in Nature Sustainability - published today by researchers from Oxford University, Ca’ Foscari University of Venice, the Euro-Mediterranean Center on Climate Change, the European Institute on Economics and the Environment and the London School of Hygiene & Tropical Medicine - brings attention to a new relevant dimension of deprivation which is clearly emerging in a warming world: cooling poverty. The study highlights the multidimensional nature of cooling poverty and introduces the new concept of systemic cooling ...

In a warming Pacific Northwest, summers are getting hotter and winters less cold, but the atmospheric patterns that influence the weather aren’t necessarily expected to become stronger or more frequent by the end of the century, according to a new Portland State University study. That means that in an overall warmer climate, models suggest we'll have the same variety of atmospheric patterns as we have now but the weather we experience from them will be warmer and, in some cases, wetter. Graham Taylor, a Ph.D. student in PSU’s ...

Boosting virtual screening with machine learning allowed for a 10-fold time reduction in the processing of 1.56 billion drug-like molecules. Researchers from the University of Eastern Finland teamed up with industry and supercomputers to carry out one of the world’s largest virtual drug screens. In their efforts to find novel drug molecules, researchers often rely on fast computer-aided screening of large compound libraries to identify agents that can block a drug target. Such a target can, for instance, be an enzyme that enables a bacterium to withstand ...

Research is being conducted around the world to confine high-temperature plasma in a magnetic field to realize nuclear fusion power generation. The most important issue is maintaining stable high-temperature plasma for a long time, which involves many challenges. The plasma confined by a magnetic field has a temperature gradient from the low-temperature periphery to the high-temperature center, where the fusion reaction takes place, with the temperature at the center being over 100 million degrees Celsius and that at the periphery being several hundred ...

It is impossible to imagine modern agriculture without plastics. 12 million tonnes are used every year. But what about the consequences for the environment? An international team of authors led by Thilo Hofmann from the Division of Environmental Geosciences at the University of Vienna addresses this question in a recent study in Nature Communication Earth and Environment. The research shows the benefits and risks of using plastics in agriculture, and identifies solutions that ensure their sustainable use.  Once celebrated as a symbol of ...
