Several studies have shown that students who attend afternoon classes tend to perform better in school than those who attend morning classes. This is due to greater synchrony between class times and students’ biological clocks. However, a study of children and adolescents revealed that this does not apply to students with attention deficit hyperactivity disorder (ADHD) or symptoms of the condition. For this group, changing school shifts does not significantly improve academic performance. The study involved 2,240 Brazilian students between the ages of six and 14. It evaluated data on reading and writing performance, negative school ...

DALLAS, Aug. 26, 2025 — With chronic disease rates rising across the U.S., healthcare systems face ongoing challenges in reducing hospital stays and readmissions.[1] Nearly 1 in 4 heart failure patients is readmitted to the hospital within 30 days of discharge,[2] and fewer than 20% receive all four guideline-directed medical therapy pillars post-discharge, despite strong evidence showing these therapies improve patient outcomes.[3] At the same time, the number of people living with chronic illness is expected to double from 2020 to 2050.[4] Remote ...

Messenger RNA, or mRNA, vaccines entered the public consciousness when they were introduced during the COVID-19 pandemic, and both Pfizer-BioNTech and Moderna used the technology in developing their highly effective vaccines to fight the virus.  Since then, scientists have been fine-tuning this vaccine delivery system to make it more effective. A Yale research team has now developed a technology that improves both the power of mRNA vaccines and their effectiveness against a host of diseases. The new technology offers the promise of expanding the reach ...

Collaborative organizations, involving government agencies, nonprofit groups and other key stakeholders, are often created to address regional challenges such as preserving watersheds – but these organizations often fail to accomplish their stated goals. A new study suggests there is a specific administrative approach that improves the ability of these collaborative groups to deliver the services they were created to provide. “These organizations tend to do a good job of planning, but then stumble when it comes to transitioning from the planning process to actually executing the projects and processes necessary to implement the plan,” says ...

CAMBRIDGE, MA -- Environmental scientists are increasingly using enormous artificial intelligence models to make predictions about changes in weather and climate, but a new study by MIT researchers shows that bigger models are not always better. The team demonstrates that, in certain climate scenarios, much simpler, physics-based models can generate more accurate predictions than state-of-the-art deep-learning models. Their analysis also reveals that a benchmarking technique commonly used to evaluate machine-learning techniques for climate predictions can be distorted by natural variations in the ...

A team from the Microbiology Department at the Icahn School of Medicine at Mount Sinai has discovered three powerful monoclonal antibodies from a person who had previously been infected with mpox (formerly known as monkeypox). These antibodies, which target the viral protein A35, blocked viral spread in laboratory in vitro tests and, most importantly, protected rodents from severe disease and fully prevented death. The findings, published August 22 in Cell, also reveal that humans previously infected with mpox carry high levels of these protective antibodies in their blood, ...

Self-driving vehicles, drones, and robotic assistants are transforming industries including transportation, logistics, and health care. With new developments in hardware, AI, and machine learning, these autonomous agents can sense their surroundings with greater accuracy, understand complex environments, and engage in sophisticated reasoning.  But despite such advancements, deploying robots in dynamic, real-world settings—and getting them to do what we want—remains difficult. “The overarching problem deals with robot capabilities,” says Cristian-Ioan Vasile, an assistant professor of mechanical engineering and mechanics in Lehigh University’s ...

A special set of neurons directs mice’s attention to or away from their peers, depending on the situation. The Kobe University discovery has implications for finding causes for neuropsychiatric conditions such as autism spectrum disorder or schizophrenia. Social interactions abound with decisions: How much time do we spend with a friend? Do we prioritize time with a friend who looks distressed? Like for all behavior, there are specialized clusters of neurons in the brain that are responsible for fine-tuning such complex behavior, and it is known that developmental defects in these areas are related ...

Summertime is beer time – even if the consumption of alcoholic beers is declining in Switzerland. And for beer lovers, there is nothing better than a head of foam topping the golden, sparkling barley juice. But with many beers, the dream is quickly shattered, and the foam collapses before you can take your first sip. There are also types of beer, however, where the head lasts a long time. ETH researchers led by Jan Vermant, Professor of Soft Materials, have now discovered just why this is the case. Their study has just been published in the journal Physics of Fluids. The ...

WASHINGTON, August 26, 2025 – Beer is one of the world’s most popular drinks, and one of the clearest signs of a good brew is a big head of foam at the top of a poured glass. Even brewers will use the quality of foam as an indicator of a beer having completed the fermentation process. However, despite its importance, what makes a large, stable foam is not entirely understood. In Physics of Fluids, from AIP Publishing, researchers from ETH Zurich and Eindhoven University of Technology investigated the stability of beer foams, examining multiple types of beer at different stages of the fermentation process. Like ...

Older adults who are overweight may face a lower risk of death in the first 30 days following major elective surgery compared with those who have a normal body mass index (BMI), new research suggests. The study, to be published August 26 in the peer-reviewed JAMA Network Open, examined outcomes in older surgical patients and found that being overweight (BMI 25–29.9) was associated with the lowest short-term mortality rates. In contrast, normal and underweight patients had significantly higher risk ...

About The Study: In this study, underrepresented in medicine (URiM) student matriculation into U.S. medical schools declined after the 2023 Supreme Court of the United States (SCOTUS) ruling, with an emergent disparity in acceptance rates of URiM applicants relative to Asian and white students. The decline in URiM student matriculation was concentrated in states without a preexisting state-level affirmative action ban, suggesting that there may be an association between the SCOTUS ruling and demographic ...

Ghent, 26 August 2025 – Belgian scientists have uncovered new details about how the immune system responds to vaccines. Dendritic cells, which are key immune messengers that help kick-start the body’s defenses, show specific responses to lipid nanoparticles. These findings, published in Cell Reports, could lead to safer and more effective vaccines.  Dendritic cells and lipid nanoparticles  Dendritic cells are among the first to detect viruses, bacteria, or other immune challenges. These cells help coordinate the immune system’s response by alerting T cells, the immune system’s soldiers trained to eliminate threats. But dendritic cells ...

A NIMS research team has discovered a unique phenomenon that the fatigue limit of steel is improved by prior cyclic deformation (fatigue) training. Based on this finding, the research team developed a novel “pre-fatigue training” technique, which successfully doubled the fatigue limit of high-strength steel by suppressing crack initiation. This strategy offers a versatile approach to improving fatigue limit in general steels, providing an effective alternative to tempering heat treatment that inevitably sacrifices tensile strength. ...

Bacteria aren’t just mindless microbes. New research from the Hebrew University of Jerusalem reveals that single bacterial cells can carry a “memory” of their past environments—passing it down through generations—before eventually forgetting. Using a new technique called Microcolony-seq, scientists uncovered hidden subpopulations inside infections, each with different survival strategies. The finding could explain why antibiotics and vaccines sometimes fail—and may point the way toward more precise treatments. [Hebrew University of Jerusalem]– ...

An international team of researchers has conducted the most comprehensive global-to-local analysis to date on long COVID risk, using disability data from the height of the pandemic to identify vulnerable populations. Drawing on the Global Burden of Disease (GBD) 2021 framework, the study examined years lived with disability (YLDs) caused by COVID-19 across 920 locations during 2020 and 2021. The results reveal that YLDs may serve as an early indicator of long COVID risk—particularly in areas where post-COVID conditions remain underreported. “Disability-related data may serve as an early warning ...
