Findings of study on how illegally manufactured fentanyl enters U.S. contradict common assumptions, undermining efforts to control supply

2025-07-07
Illegally manufactured fentanyl kills a significant number of people in the United States and Canada every year. Since the emergence of modern heroin markets in the late 1960s, controlling supply has been associated with important reductions in opioid use and harms in several cases worldwide. But these efforts depend on understanding the dominant drug-trafficking routes. In a new analysis, researchers developed an index to compare U.S. counties’ proportion of large seizures against their proportion of the national population. Their findings counter ...

Three years in, research shows regional, personal differences in use of 988 lifeline

2025-07-07
Who is most likely to use the 988, the national suicide and crisis lifeline launched on July 16, 2022?  Two studies led by researchers at the NYU School of Global Public Health find both geographic differences and personal factors that shape where people might seek help during mental health crises. For instance, people in western and northeastern states are more likely to have called 988 than those in the South; similarly, Democrats are more inclined to say that they would use 988 than Republicans. In addition, more than 10 percent of calls came from veterans. The findings, published in JAMA Network ...

Beyond the alpha male

2025-07-07
To the point Power relationships between males and females are less clear-cut than expected: In most species, neither sex clearly dominates over the other. Evolutionary factors shape intersexual power: Males have power when they can physically outcompete females, while females rely on different pathways to achieve power over males. New findings by researchers at the University of Montpellier, the Max Planck Institute for Evolutionary Anthropology in Leipzig, and the German Primate Center in Göttingen resolve why male-female power ...

For fish, hovering is not restful

2025-07-07
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 study shakes up received ideas on male domination among primates

2025-07-07
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 ...

Study uncovers how harmful RNA clumps form — and a way to dissolve them

2025-07-07
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 ...

A new perspective on designing urban low-altitude logistics networks subhead: Balancing cost, safety, and noise through co-evolutionary multi-objective optimization

2025-07-07
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. A research team from Beihang University has developed a new framework that tackles this challenge head-on.

Mobile mindfulness meditation apps may improve attention

2025-07-07
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, ...

Positive emotions may strengthen memories

2025-07-07
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 ...

Audit published in research integrity and peer review identifies key failings of institutional animal care and use committees

2025-07-07
WASHINGTON, D.C.— A focused review published in the journal Research Integrity and Peer Review has found that Institutional Animal Care and Use Committees (IACUC) provide surprisingly little protection for animals in research, that searches for alternatives to animal use are seldom conducted, and that, when performed, they are inadequate. For the first time since the publication of “The Guide for the Care and Use of Laboratory Animals” (The Guide) in 1963, research scientists are recommending a new guide that puts replacement of animals in research and IACUC member training ...

Treatment with Virtual Reality works quickly and effectively for psychosis

2025-07-07
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 ...

Following the pigeon's gaze

2025-07-07
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 ...
