Move over gym rats. Bumble bees are now the true masters of macros. In the first long-term, community-level field study of wild bumble bee nutrition, a team of ecologists led by Northwestern University and the Chicago Botanic Garden discovered that wild bees aren’t just flitting from flower to flower, collecting pollen at random. Instead, they are strategically targeting flowers that enable them to carefully balance their protein, fat and carbs. Focusing on pollen consumption, the study revealed that coexisting bee species occupy two distinct nutrient niches. Larger bodied bees with longer tongues prefer pollen that’s ...

A relatively new class of insecticide that can be disseminated on something the size of a sheet of paper offers protection for up to a year against mosquitoes that spread malaria, as well as dengue, West Nile, yellow fever, and Zika, UC San Francisco researchers have found. In a systematic review of more than 25 years of data on some 1.7 million mosquitoes, researchers concluded that this form of repellent — called a “spatial emanator” because it distributes chemicals through the air — can prevent more than ...

Psychotherapy leads to measurable changes in brain structure. Researchers at Martin Luther University Halle-Wittenberg (MLU) and the University of Münster have demonstrated this for the first time in a study in “Translational Psychiatry” by using cognitive behavioural therapy. The team analysed the brains of 30 patients suffering from acute depression. After therapy, most of them showed changes in areas responsible for processing emotions. The observed effects are similar to those already known from studies on medication. Around ...

New research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King’s College London, in partnership with the University of Bath, has found that the reasons why a person chooses to use cannabis can increase their risk of developing paranoia.  The use and potency of cannabis is increasing worldwide, and dependence and cannabis-induced psychosis are also greatly increasing as a result, especially in North America. Two new research papers, both using data from Cannabis & Me - the largest survey of its kind - have identified key risk factors associated ...

Nearly 80% of US neurologists prescribing drugs for multiple sclerosis (MS) received at least one pharma industry payment, with higher volume prescribers more likely to be beneficiaries, finds a 5 year analysis of Medicare database payments, published in the open access journal BMJ Open. And those in receipt of these payments were more likely to prescribe that company’s drugs, especially if the sums involved were larger, sustained, and recent, the findings indicate. Because of the lifelong nature of MS, effective therapies are usually continued indefinitely unless a patient’s clinical response changes, explain the researchers. And MS drug prescriptions are ...

A team of astronomers has detected for the first time a growing planet outside our solar system, embedded in a cleared gap of a multi-ringed disk of dust and gas. The team, led by University of Arizona astronomer Laird Close and Richelle van Capelleveen, an astronomy graduate student at Leiden Observatory in the Netherlands, discovered the unique exoplanet using the University of Arizona's MagAO-X extreme adaptive optics system at the Magellan Telescope in Chile, the U of A's Large Binocular Telescope in Arizona and the Very Large Telescope at the European Southern Observatory in Chile. ...

Making a smoothie, going for an evening walk, or having empathy for a loved one are all examples of executive functions that are controlled by the brain’s frontal cortex. This area of the brain goes through profound change throughout adolescence, and it is during this time that abnormalities in maturing circuits can set the stage for neurodevelopmental disorders, such as schizophrenia and ADHD. Researchers at the Del Monte Institute for Neuroscience at the University of Rochester have discovered that microglia, the brain’s immune cells, ...

Recently, defect detection systems using artificial intelligence (AI) sensor data have been installed in smart factory manufacturing sites. However, when the manufacturing process changes due to machine replacement or variations in temperature, pressure, or speed, existing AI models fail to properly understand the new situation and their performance drops sharply. KAIST researchers have developed AI technology that can accurately detect defects even in such situations without retraining, achieving performance improvements ...

Alcohol-associated liver disease (ALD) is a major cause of liver transplantation and death worldwide, and its impact is only growing. In 2022, the annual cost of ALD in the United States was $31 billion. By 2040, this number could be as high as $66 billion. ALD has limited therapeutic options, so scientists are looking for new ways to target the molecular biology of ALD to help prevent its occurrence or reduce its severity. Now, scientists at University of California San Diego School of Medicine have found that chronic alcohol use impairs the production of a key cellular signaling ...

August 26, 2025 Companies 'dumbed down' cryptocurrency disclosures in good markets prior to reporting standardization, Rotman research finds Toronto - In the run-up to the introduction of accounting standards for the reporting of cryptocurrency, companies took various approaches to disclosing their involvement with the novel exchange medium. Investors had to rely more on contextual narrative explanations about a company's crypto involvement instead of getting it from numerical data. An analysis of reporting ...

Why this matters: Obituaries function as time capsules that reflect what people, at any given moment in history, understand to be a life well-lived. By studying how obituaries evolve across time and context, we can gain deeper insight into how societies define a worthy life, express loss and pass on values across generations. New MSU-led research takes a novel approach to the psychological study of legacy by focusing on how individuals are actually remembered by others instead of how they wish to be remembered. Legacy motivations influence a range of real-world ...

Key takeaways: Storm surge and rainfall — not wind — cause the majority of hurricane deaths, yet are absent from the current warning system. Researchers developed and tested the Tropical Cyclone Severity Scale, which incorporates all three hazards and can rate storms up to Category 6. Study shows people are more likely to correctly identify risks and evacuate when informed using the new scale. TAMPA, Fla. (Aug. 26, 2025) – Wind alone does not account for all hurricane-related fatalities. Storm surge and rainfall do as well. Yet the current warning system – the Saffir-Simpson Hurricane ...

There’s more than one way to build a honeybee hive, depending on the needs of the bees, according to a study published August 26th in the open-access journal PLOS Biology by Golnar Gharooni-Fard of the University of Colorado Boulder, USA, and colleagues. Honeybees are renowned for their ability to build intricate hives where they can store their food and raise their larvae. Hive construction is the collaborative effort of thousands of hard-working bees, which also demonstrate a knack for adjusting their honeycomb structures to account for available space and resources. In this study, Gharooni-Fard and colleagues ...

A deep sea worm that inhabits hydrothermal vents survives the high levels of toxic arsenic and sulfide in its environment by combining them in its cells to form a less hazardous mineral. Chaolun Li of the Institute of Oceanology, CAS, China, and colleagues report these findings in a new study published August 26th in the open-access journal PLOS Biology. The worm, named Paralvinella hessleri, is the only animal to inhabit the hottest part of deep sea hydrothermal vents in the west Pacific, where hot, mineral-rich water spews from the seafloor. ...

A new HIV antiretroviral shows promise as a long-acting, oral prophylactic agent, according to a new study by Izzat Raheem, Tracy Diamond and colleagues from Merck & Co., Inc., Rahway, NJ, USA, published August 26th in the open-access journal PLOS Biology. HIV pre-exposure prophylaxis (PrEP) is a key part of reducing the number of new HIV infections. The most common oral PrEP therapies, consisting of once-daily pills, are highly effective at protecting people from acquiring HIV, but they only work if taken properly. Currently, the only long-acting PrEP therapies require injection by a healthcare provider, which isn’t always feasible for people. Long-acting, oral PrEP therapies ...

Today a desert – as far as the eye can see. However, anyone looking more closely will discover hundreds of images carved into the rock. This ancient Egyptian graffiti attests to the fact that a new claim to sovereignty emerged here on the periphery over 5,000 years ago. One of these kings was known as Scorpion. He demonstrated his power with portrayals of himself as a divine ruler and with brutal depictions of violence. Together with Mohamed Abdelhay Abu Bakr, Egyptologist Prof. Dr. Ludwig Morenz from the University of Bonn has now published ...

WEST LAFAYETTE, Ind. — New results from OSIRIS-REx, NASA’s first asteroid sample return mission, reveals why some gray asteroids reflect light at different wavelengths, like red or blue, more strongly. How these asteroids reflect light at red and blue wavelengths can give deeper insights into the evolution of rocky bodies in the solar system. It also enables future research. By having a better understanding and comparing what telemetry and telescope data say about an asteroid with what its actual surface particles ...

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 ...
