Severe sepsis from bacterial or viral infections can be life-threatening and even people recovering from severe sepsis may experience long-lasting effects on the immune system, making them more susceptible to recurrent infections. The causes for this sepsis-induced immune suppression are not well understood and lack an effective treatment. To better understand the cause, Katherine MacNamara and colleagues from Albany Medical College, USA, analyzed the blood stem cells of mice with prior sepsis and their results were recently published in the journal Stem Cell Reports. During ...

Concurrent occurrences of heatwaves and extreme short-term sea level rises at the same coastal locations significantly increased between 1998 and 2017 when compared to the preceding twenty years, reports a study published in Communications Earth & Environment. The study also suggests that these events may be five times more likely to occur between 2025 and 2049 under a modelled high emissions scenario. A so-called ‘concurrent heatwave and extreme sea level’ (CHWESL) event is when a heatwave and an extreme short-term sea level rise occur at the same coastal location over the same time period. Although they ...

Plants can be temperamental. Even weeds along the side of highways or pushing their way up in the cracks of concrete sidewalks can get stressed out by dehydration, cold, excess salt and more. Researchers at Hiroshima University have identified 14 genes that thale cress — a plant commonly used in genetic investigations since its genome is well documented — express more when responding to five specific stressors, as well as eight genes that the plant suppresses. They published their results on March 22 in Frontiers in Plant Science.  “Abiotic stresses — as opposed to biotic stresses like pests or disease — such as drought, salinity and cold negatively ...

Thiazolidinediones (TZDs) are a class of drug that can be used to treat type 2 diabetes by reversing insulin resistance, one of the main hallmarks of the disease. While TZDs were extremely popular in the 1990’s and early 2000’s, they have fallen out of use among physicians in recent decades because they were discovered to cause unwanted side effects, including weight gain and excess fluid accumulation in body tissues. Now, researchers at University of California San Diego School of Medicine are ...

As artificial intelligence is inevitably woven into the workplace, teams of humans will increasingly collaborate with robots on complex design problems, such as those in the auto, aviation, and space industries. “Right now, design is mainly done by humans, and it’s based on their expertise and intuitive decision-making, which is learned over time,” says A. Emrah Bayrak, an assistant professor of mechanical engineering and mechanics in Lehigh University’s P.C. Rossin College of Engineering and Applied Science. “Usually, ...

OAK BROOK, Ill. – A new study showed that a non-invasive imaging test can help identify patients with coronary artery blockage or narrowing who need a revascularization procedure. The findings were published as a Special Report in Radiology: Cardiothoracic Imaging, a journal of the Radiological Society of North America (RSNA). Doctors use coronary CT angiography (CTA) to diagnose narrowed or blocked arteries in the heart. A CTA exam receives a score from mild (0-1) to moderate (2-3) to severe (4-5). Patients ...

Many people are familiar with the principle of electronic excitation from their physics lessons: electrons in atoms or molecules absorb energy, typically from light, and rise to a higher energy level. This can have various consequences – in photovoltaic technology, the phenomenon ensures that electricity can be generated from sunlight. Measuring electronic excitation according to scientific standards and investigating how excited electrons influence each other is a real challenge: “Electronic excitation and the subsequent processes take place extremely quickly, many things happen simultaneously“, explains Tobias Brixner, Chair of Physical Chemistry ...

The maritime profession is among the world’s oldest professions, and today’s shipping is based on long and proud traditions. Professional pride and commitment are often deeply ingrained in seafarers, and for many, the job is more of a way of life. New technologies will bring about major changes in the work of bridge officers, who have the ultimate responsibility on board Norwegian vessels. Strong doubts about safety “Bridge officers rely on automated systems that are already found on board, such as advanced autopilot systems. However, there is strong scepticism, almost mistrust, that increased automation and autonomous ...

People who use willpower to overcome temptations and achieve their goals are perceived as more trustworthy than those who use strategies that involve external incentives or deterrents – such as swear jars or internet-blocking apps – according to research published by the American Psychological Association. “The knowledge that people can use external commitment strategies to overcome self-control problems has existed in some form for thousands of years. Since at least the time of Homer and Odysseus, the focus has primarily been on the efficacy of these strategies for the person choosing to engage ...

CLEVELAND—A recent study by Case Western Reserve University used national data from U.S. military veterans with diabetes to validate and modify a widely accepted model used to predict the risk of heart failure in diabetic patients. The model, called the WATCH-DM score, is used to predict the likelihood of heart failure in diabetes patients within five years. But because it overlooks the influence of social determinants of health‚ such as housing, food and a patient’s neighborhood, the researchers used a social deprivation index (SDI), a multi-component summary score, to adjust the WATCH-DM score.  The SDI, introduced by the Robert ...

The nose or the gut? For the past two decades, the scientific community has debated the wellspring of the toxic proteins at the source of Parkinson’s disease. In 2003, a German pathologist, Heiko Braak, MD, first proposed that the disease begins outside the brain. More recently, Per Borghammer, MD, with Aarhus University Hospital in Denmark, and his colleagues argue that the disease is the result of processes that start in either the brain’s smell center (brain-first) or the body’s intestinal tract (body-first).     A new hypothesis paper appearing in the Journal of Parkinson’s ...

A major new research project will investigate how and why groups of animals from the same species fight one another. By focussing on warlike species – mongooses and termites – researchers aim to understand how evolution can lead to extreme aggression between groups, the consequences of this and the factors that can lead to peace. The results will help to explain why violence between rival groups evolves in some species but not others, or between some groups and not others – with implications for our understanding of human evolution. The research team, led by Professor ...

[Vienna, April 11, 2024] – The European Research Council (ERC) has awarded an Advanced Grant to Mirta Galesic, a resident scientist at the Complexity Science Hub (CSH), to study the intricate workings of collective adaptation. The project aims to provide insights into why collectives – from families to entire societies – can be stuck in deadlocks about important problems, such as resolving long-standing political conflicts; or why they sometimes appear incapable of finding seemingly obvious solutions, such ...

Fukuoka, Japan—Kyushu University researchers have shed new light into a critical question on how baby stars develop. Using the ALMA radio telescope in Chile, the team found that in its infancy, the protostellar disk that surrounds a baby star discharges plumes of dust, gas, and electromagnetic energy. These 'sneezes,' as the researchers describe them, release the magnetic flux within the protostellar disk, and may be a vital part of star formation. Their findings were published in The Astrophysical Journal. Stars, including our Sun, all develop from what are called stellar nurseries, large ...
