Greater attention needs to be paid to malnutrition in the sick and elderly, researchers say
As many as half of all patients admitted to hospital and other healthcare facilities are malnourished. This has serious consequences for the individual in terms of unnecessary suffering, poorer quality of life and mortality. Providing nutrients can alleviate these problems, but not enough attention is paid to this knowledge, according to researchers in a new article.
Charting an equitable future for DNA and ancient DNA research in Africa
The American Journal of Human Genetics recently published a perspective piece on the need for an equitable and inclusive future for DNA and ancient DNA (aDNA) research in Africa. The paper highlights the fact that, while DNA from ancient and living African peoples is increasingly critical to the study of human evolution, African scientists remain starkly underrepresented in this field.
User control of autoplay can alter awareness of online video 'rabbit holes'
A new study suggests that giving users control over the interface feature of autoplay can help them realize that they are going down a rabbit hole. The work has implications for responsibly designing online content viewing platforms and algorithms, as well as helping users better recognize extreme content.
Living near oil and gas activity linked to poor mental health during preconception
A new study suggests that people who are trying to conceive and live close to oil and gas development sites have a heightened risk of developing adverse mental health outcomes. The study found that people who lived within roughly six miles of active oil and gas development had greater development of moderate-to-severe depressive symptoms, compared to people living 12 to 31 miles away from this activity. High perceived stress was elevated among people living just 1.25 miles away from oil and gas development, and greater intensity of oil and gas production also contributed to high perceived stress.
Hatcheries can boost wild salmon numbers but reduce diversity, studies find
The ability of salmon hatcheries to increase wild salmon abundance may come at the cost of reduced diversity among wild salmon, according to a new study.
Introducing co-cultures: When co-habiting animal species share culture
Cooperative hunting, resource sharing, and using the same signals to communicate the same information -- these are all examples of cultural sharing that have been observed between distinct animal species. In a new article, researchers introduce the term 'co-culture' to describe cultural sharing between animal species. These relationships are mutual and go beyond one species watching and mimicking another species' behavior -- in co-cultures, both species influence each other in substantial ways.
Researchers uncover brain region's role in hearing and learning
The human brain is remarkably adept at adjusting what we hear based on contexts, like our current environment or priorities, but it's still unknown how exactly the brain helps us detect, filter and react to sounds. Now, biologists are a step closer to solving that mystery. Using an animal model, the researchers found that the orbitofrontal cortex (OFC), a brain region associated with decision-making but not typically linked to hearing, plays a central role in helping the auditory cortex (a primary hearing center of the brain) adapt to changing contexts or situations.
How risk-averse are humans when interacting with robots?
How do people like to interact with robots when navigating a crowded environment? And what algorithms should roboticists use to program robots to interact with humans? These are the questions that a team of mechanical engineers and computer scientists sought to answer in a recent study.

Researchers explore the role of children in community participatory planning process
Child-friendly cities prioritize safe environments, healthcare, education, green spaces, and children's participation in decision-making processes. However, children are consulted only for ideas and often excluded from public spaces. A study tackled pedestrian safety around school zones using child-inclusive participatory planning. Their approach included field work, community mapping, and collaborative solution development. Children effectively identified safety risks, shaping a robust safety plan with potential to significantly enhance community safety.
Targeted home systems to remove PFAS more cost-effective than system-wide solutions
PFAS, the potentially cancer-causing chemicals known as 'forever chemicals', have become an increasing concern in home drinking water. Solutions to reduce the risk of exposure range from mandated municipal-level water treatment to under-the-sink home treatment systems. But are consumers willing to foot the bill for an additional treatment system to help municipalities meet new federal drinking water regulations? Researchers found that they are, if it helps reduce the risk and fits their budget.
People tend to become less narcissistic as they age from childhood through older adulthood. However, differences among individuals remain stable over time -- people who are more narcissistic than their peers as children tend to remain that way as adults, the study found.
Many youths continue to take opioids months after surgical procedures
A multi-institutional study found that 1 in 6 youths fill an opioid prescription prior to surgery, and 3% of patients were still filling opioid prescriptions three to six months after surgery, indicating persistent opioid use and possible opioid dependence. The study underscores that more guidance is needed to steer clinicians away from prescribing opioids when they are not likely to be needed and recognizing patient-specific risk factors for persistent opioid use.
A new study finds four in 10 cancer cases and about one-half of all cancer deaths in adults 30 years old and older in the United States (or 713,340 cancer cases and 262,120 cancer deaths in 2019) could be attributed to modifiable risk factors, including cigarette smoking, excess body weight, alcohol consumption, physical inactivity, diet, and infections.

AI Chatbots have shown they have an 'empathy gap' that children are likely to miss
Artificial intelligence (AI) chatbots have frequently shown signs of an 'empathy gap' that puts young users at risk of distress or harm, raising the urgent need for 'child-safe AI', according to a new study. The research urges developers and policy actors to prioritize AI design that take greater account of children's needs. It provides evidence that children are particularly susceptible to treating chatbots as lifelike, quasi-human confidantes, and that their interactions with the technology can go awry when it fails to respond to their unique needs and vulnerabilities. The study links that gap in understanding to recent reports of cases in which interactions with AI led to potentially dangerous situations for young users.
Holiday season already? Anticipation might make time seem to fly
Christmas or Ramadan might seem to come around more quickly each year, for people who pay more attention to time, are more forgetful of plans, and love a good holiday, according to a new study. Researchers suggest this could mean that someone's experience of time is shaped not only by what they've done, but what is left to do.

Trust, more than knowledge, critical for acceptance of fully autonomous vehicles
While not yet on the market, fully autonomous vehicles are promoted as a way to make road travel dramatically safer, but a recent study found that knowing more about them did not improve people's perception of their risk. They needed to have more trust in them too. This study adds to the evidence from other research that knowledge alone is not enough to sway people's attitudes toward complex technology and science, such as gene editing or climate change. In this case, researchers found that trust in the autonomous vehicles' reliability and performance played the strongest role in improving perceptions of the technology's risk.
