A study of 6- to 11-year-old children in five countries found that children believed people were more willing to help and share when they voluntarily decided to do so rather than when asked. However, the extent to which demands reduce this perceived willingness varies by culture. This research developmental psychology. According to self-determination theory, a widely used theoretical framework in psychology, humans have three basic psychological needs. These are the needs for autonomy, competence, and relatedness. Autonomy means feeling that one’s actions are freely chosen and personally approved, or self-determined. Competence means feeling competent, effective, and able to overcome challenges.…

New research from the University of Surrey, the John Innes Center and the Quadrum Institute for Biosciences suggests that taking vitamin D2 can reduce your body’s levels of vitamin D3, the more efficient form of vitamin D. Many people take vitamin D supplements to support bone and immune health, particularly during the winter months, to meet the UK government’s recommendation of 10 micrograms (μg) daily. There are two forms of vitamin D supplements available: vitamin D2 and vitamin D3. Researchers have found that taking vitamin D2 supplements can reduce vitamin D3 levels in the body. Vitamin D3 is the vitamin…

NASA’s Psyche spacecraft approached Mars on May 15, flying within 2,864 miles (4,609 kilometers) of the planet’s surface, continuing its long journey through deep space. During the encounter, the spacecraft took a series of images. It included an impressive sight of the double-ring Huygens crater, surrounded by Mars’ cratered southern highlands. This image was taken using Psyche’s multispectral imager equipment and highlights the Red Planet’s rugged and ancient terrain. Mars gravity assist powers spirit missions The Mars flyby was more than just a photo opportunity. NASA used the planet’s gravity to increase the spacecraft’s speed and adjust its orbit without…

A new study suggests that the popular weight loss drug Wigovy may have a higher risk of a rare eye disease that can lead to sudden vision loss compared to other semaglutide drugs. This condition is called ischemic optic neuropathy (ION) and occurs when blood flow to the optic nerve is reduced or blocked. This can result in sudden partial or complete blindness in one or both eyes. Researchers reported that Wegovy showed the strongest association with IONs among the semaglutide-based GLP-1 drugs analyzed in the study. British Society of Ophthalmology Journal. The findings also suggest that risk signals are…

Children who experience Attention Deficit Hyperactivity Disorder may have symptoms that last, come and go, or disappear completely as they grow older. A recent study published in Nature Mental Health revealed that these different symptom pathways are physically reflected in brain development during adolescence, particularly the growth and thinning of certain areas of the brain. This study highlights the potential of using brain scans to predict future symptom changes and emphasizes the need for long-term monitoring even after treatment begins. Attention Deficit Hyperactivity Disorder, commonly known as ADHD, affects approximately 5% of children and adolescents worldwide. This developmental condition often…

When NASA scientists first received a radio burst from the sun in August 2025, the signal initially appeared to be a routine occurrence. Solar radio bursts are fairly common and usually disappear within a few hours, sometimes even a few days. This event was anything but ordinary. The radio burst never died out and lasted for an astonishing 19 days, setting a new record for this kind of solar activity. The newly observed outburst was much more persistent than scientists expected, as the longest previously known phenomenon lasted just five days. Strange solar radio signal breaks previous records This event…

Researchers at Helmholtz München, Ludwig-Maximilians-Universität München (LMU), and several partner institutions have developed an artificial intelligence (AI) system that can map disease-related changes throughout the body of mice in cellular-level detail. Using a new platform known as MouseMapper, the research team discovered widespread inflammation and previously unknown neurological damage associated with obesity. This study identified similar molecular patterns in human tissue, suggesting that important aspects of obesity-related neurological damage may occur in both mice and humans. The research results were published in a magazine nature. Obesity is known to affect more than just body weight and metabolism. It can alter…

Recent research published in journals psychology, crime, law suggest that certain deep psychological patterns, particularly feelings of entitlement and a desire to punish others, are associated with an interest in secretly removing a condom during sex. The findings provide evidence that targeted mental health interventions may help reduce this particular form of sexual violence by addressing dysfunctional thinking. Nonconsensual condom removal, commonly known as stealth, occurs when a condom is secretly removed or damaged before or during sex, without the partner’s knowledge or consent. Because condom use represents a mutual agreement regarding sexual safety, secretly altering that agreement turns a…

Demand for lithium is surging as automakers increase production of electric vehicles and energy companies build large battery systems to support wind and solar power generation. However, the lithium production process remains time-consuming and environmentally costly. Current extraction methods are most effective for high-quality deposits located in limited areas, but they also consume vast amounts of land and water. Now, researchers at Columbia Engineering have developed a new lithium extraction technology that can speed up production, reduce pollution and tap into reserves that are difficult to access with existing technologies. Their findings were published in the journal Jouledescribes a process…

Brisk walking does more than just get your heart rate up. You may also notice a noticeable increase in your imagination after about an hour. A recent study tracked body movement and creative thinking in real time and found that certain time windows of moderate exercise were associated with the generation of more original ideas. The researchers published their results in the journal Sport, Exercise and Performance Psychology. Human creativity is a cognitive skill needed to perform daily life. We are always faced with endless problems with no obvious solutions. Solving these unstructured problems requires generating completely original and useful…
