For more than two decades, astronomers have been puzzled by the striking pattern of bright, evenly spaced stripes in radio waves from club pulsars, the dense remnants of supernovae recorded by Chinese and Japanese astronomers in 1054. In 2024, theoretical astrophysicists at the University of Kansas proposed a solution that explains much of this unusual “zebra” pattern. Now, through sophisticated analysis, he has identified gravitational lensing as the final missing ingredient needed to fully explain the phenomenon. “Gravity changes the shape of space-time,” said Mikhail Medvedev, a professor of physics and astronomy at the University, who will present his findings…
Recent research published in journals drug and alcohol addiction Our findings suggest that sleep deprivation in people with alcohol use disorders is closely associated with heightened negative emotions and specific changes in brain activity. The results of this study indicate that treating sleep disorders may be a practical way to help improve mood and emotional regulation in people recovering from alcoholism. Addiction is often viewed as a three-stage cycle consisting of binge drinking, experiencing negative emotions during withdrawal, and obsession or craving for the substance. Previous research has shown that sleep problems can alter mood and reward processing in the…
Solar power plays an important role in efforts to reduce dependence on fossil fuels and combat climate change. The sun supplies Earth with enormous amounts of energy every second, but modern solar cells can capture only a tiny fraction of the energy. This limitation is due to a “physical ceiling” that has been difficult to overcome for many years. In a study published in Journal of the American Chemical Society On March 25, scientists from Japan’s Kyushu University, in collaboration with collaborators from Germany’s Johannes Gutenberg University (JGU) Mainz, developed a new way to overcome this barrier. They used a…

Reevaluating one of the most famous psychological experiments in history, a recent analysis of audio recordings reveals that subjects who appeared to follow orders to administer severe electric shocks were actually breaking the rules of scientific research most of the time. The authors suggest that this routine violation of experimental procedures may have turned the laboratory into a site of unauthorized violence and changed our understanding of compliance and coercion. The study was published in the journal Political Psychology. In the early 1960s, American social psychologist Stanley Milgram conducted a series of experiments to understand how ordinary people are induced…
Erythritol is a main ingredient in many modern foods, from low-carb ice cream and keto protein bars to “unsweetened” sodas. But new research from the University of Colorado Boulder suggests that this widely used sugar substitute may have a significant drawback. Scientists have found that it can affect brain cells and increase the risk of stroke. The survey results are Journal of Applied Physiology. “Our study adds to the growing body of evidence suggesting that nonnutritive sweeteners, which have generally been considered safe, are not free from adverse health effects,” said senior author Christopher D’Souza, professor of integrative physiology and…
Recent research published in Social psychology and personality science It has been suggested that people with social anxiety experience more meaningful and playful social interactions when communicating through digital channels and small groups. This finding provides evidence that adjusting the social environment to feel more in control tends to help people with social anxiety make the most of their daily social interactions. Social interaction plays a central role in human well-being and a sense of belonging. The benefits of these connections are not felt equally by everyone. People who experience trait social anxiety often feel intense fear or discomfort in…
Anyone who has had a severe stomach illness will recognize this pattern. Even after the worst symptoms have subsided, people often lose their appetite, and recovery may take time. This same effect is experienced by millions of people around the world living with long-term parasitic infections. Despite how common it is, scientists have a hard time pinpointing the exact cause of this loss of appetite. Researchers at the University of California, San Francisco have identified a biological pathway that links the gut’s immune response to the brain during parasitic infections. Their research shows how signals from the immune system can…
Researchers have discovered how a key protein turns on brown fat by helping build blood vessels and nerve connections needed for heat production. The survey results are nature communicationsproposes a new way to tackle obesity that focuses on increasing the body’s energy expenditure rather than reducing appetite. Brown fat and how it burns calories Most of the fat in the body is white fat, which stores excess energy and can cause obesity when accumulated. In contrast, brown fat exists in small amounts and plays a specialized role in regulating body temperature and supporting metabolic health. When exposed to cold, brown…
Newly discovered ape fossils in northern Egypt are changing the way scientists view early human evolution, researchers report. The discovery suggests that the closest ancestors of modern apes may have originated in North Africa, rather than East Africa, which has long been the main focus of fossil research. “(The) discovery (…) confirms that paleontologists may have been looking for crown hominin ancestors in the wrong place,” David Alba and Julia Arias-Martorell write in a related Perspective. The fossil is about 17 to 18 million years old and belongs to a newly identified species called Maslipithecus. It is considered the closest…
