Fish make hanging motionless in the water column look effortless, and scientists had long assumed that this meant it was a type of rest. Now, a new study reveals that fish use nearly twice as much energy when hovering in place compared to resting.  The study, led by scientists at the University of California San Diego’s Scripps Institution of Oceanography, also details the biomechanics of fish hovering, which includes constant, subtle fin movements to prevent tipping, drifting or rolling. This more robust understanding of how fish actively maintain their position could inform the design of underwater robots ...

A Smithsonian-led team of researchers have discovered North America’s oldest known pterosaur, the winged reptiles that lived alongside dinosaurs and were the first vertebrates to evolve powered flight. In a paper published today, July 7, in Proceedings of the National Academy of Sciences, researchers led by paleontologist Ben Kligman, a Peter Buck Postdoctoral Fellow at the Smithsonian’s National Museum of Natural History, present the fossilized jawbone of the new species and describe the sea gull-sized ...

While knowledge of the female dominance spectrum among certain primate species dates back to the 1960s, research precisely quantifying the degree of one gender’s dominance over the other was lacking. A team of scientists collected data from 253 populations representing 121 primate species in order to study confrontations between males and females. It also analysed the contexts in which one or the other tend to dominate. Scientists then tested five evolutionary hypotheses to better understand these power relations. Females tend to dominate in species [3] where they have strong control over their reproduction. Their dominance is also more frequent in societies ...

BUFFALO, N.Y. — Look inside a brain cell with Huntington’s disease or ALS and you are likely to find RNA clumped together. These solid-like clusters, thought to be irreversible, can act as sponges that soak up surrounding proteins key for brain health, contributing to neurological disorders.  How these harmful RNA clusters form in the first place has remained an open question. Now, University at Buffalo researchers have not only uncovered that tiny droplets of protein and nucleic acids in cells contribute to the formation of RNA clusters but also demonstrated a way to prevent and disassemble ...

As cities worldwide begin embracing low-altitude logistics to support rapid, flexible deliveries by drones, urban planners face an increasingly difficult challenge: how to design an aerial delivery network that balances cost efficiency, safety, and noise impact.

Their study presents a multi-layered, hub-and-spoke logistics network design optimized using a dual-population co-evolutionary algorithm. This method not only improves route planning and facility placement but also explicitly accounts for noise constraints — a key concern for residents living ...

Studies suggest mindfulness meditation can improve cognition, but few researchers have examined whether virtual mindfulness meditation apps are effective. In a new eNeuro paper, Andy Kim et al., from the University of Southern California, assessed attention control in adults following about a month of mindfulness meditation guided by a mobile app.  In participants of all ages, mindfulness improved attention control as measured by reliable eye movement tasks established to assess how quickly people orient their attention. A control group that listened to an audio book did not have this cognitive improvement. Notably, self-reported measures of cognitive ability, ...

How do emotions influence memory? In a collaboration between Hangzhou Normal University and Nanjing Normal University, Xi Jia led a study to explore whether emotions shape how well people remember meaningless, or neutral, images.  As detailed in their new JNeurosci paper, the researchers recorded the brain activity of 44 study participants as they viewed meaningless images of squiggles followed by images meant to evoke positive, neutral, or negative emotions. Researchers presented each squiggle–emotional image pair to participants three times. During image pair learning sessions, positive emotions promoted ...

A new study from the University of Colorado Anschutz Medical Campus reveals that individuals living with Polycystic Ovary Syndrome (PCOS) often feel dismissed, misunderstood and underserved by the healthcare system.

Treatment with Virtual Reality appears to work very well for people with psychosis. It works faster than the current treatment with cognitive behavioural therapy and is at least as effective. This is evident from research conducted by UMCG psychiatrist Wim Veling. 'I hope that this application of Virtual Reality will soon be available in all mental health care facilities. Cognitive behavioural therapy is the most important psychological treatment for paranoid ideas in patients with psychotic disorders. In a study, Veling compared the effect of treatment with Virtual Reality-based therapy with current standard therapy. 'With ...

There's something magnetic about a group of people looking in the same direction – others will follow their gazes to see what has caught their attention. But is the same true for animals like pigeons – and, if so, does it make a difference, if just one pigeon or a large group of them looks at something? A team of animal behaviour researchers around Fumihiro Kano (team leader) and Mathilde Delacoux from the University of Konstanz examined the gaze following behaviour in groups of pigeons. A story about why it is important to know where pigeons are looking. Following the gaze Gaze following ...

Since their first detection, powerful bursts of X-rays from distant galaxies, known as fast X-ray transients (FXTs), have mystified astronomers. FXTs have historically been elusive events, occurring at vast distances away from Earth and only lasting seconds to hours. Einstein Probe (EP), launched in 2024, is dedicated to observing transient events in the X-ray and is changing the game for astronomers looking to understand the origin of these exotic events. In January 2025 EP alerted astronomers to the nearest FXT known at the time, named EP 250108a. Its proximity to Earth (2.8 billion light-years away) ...

During the coronavirus pandemic, german universities had to act quickly: Lectures and seminars had to be offered online via Zoom. After the pandemic-related lockdowns, many lecturers introduced synchronous hybrid teaching/learning settings. These are courses in which students can take part either on site in the seminar room or online at the same time. Students are therefore faced with the decision every session as to whether they want to take part in the course online or on site. Three researchers from the Professorship of Adult Education/Continuing Education at the Institute of Education at Julius-Maximilians-Universität Würzburg (JMU) have investigated the factors ...

High-resolution flow field data are essential for accurately evaluating the aerodynamic performance of aircraft. However, acquiring such data via large-scale numerical simulations or wind tunnel experiments is highly resource-intensive. Flow field super-resolution techniques aim to reconstruct high-resolution information from low-resolution data, significantly improving data acquisition efficiency. With the rapid advancement of artificial intelligence, especially deep learning, neural network-based super-resolution methods have been widely adopted for flow field reconstruction. Nonetheless, these ...
