Are Newton’s Laws of Gravity Wrong: Observation Puzzles Researchers

Lead Image: Astrophysicists have made a puzzling discovery while analyzing certain star clusters. The finding challenges Newton’s laws of gravity. Instead, the observations are consistent with the predictions of an alternative theory of gravity. (Artistic concept of strange gravity.) Finding cannot be explained by classical assumptions. An international team of astrophysicists has made a puzzling discovery while analyzing certain star clusters. The finding challenges Newton’s laws of gravity, the researchers write in their publication. Instead, the observations are consistent with the predictions of an alternative theory of gravity. However, this is controversial among experts. The results have now been published…

Webb Space Telescope Uncovers Surprising Cosmic Knot in the Early Universe

Lead Image: Webb’s view of the extremely red quasar SDSS J165202.64+172852.3. The quasar SDSS J165202.64+172852.3 is depicted here by the NASA/ESA/CSA James Webb Space Telescope to demonstrate the distribution of gas around the object. This visual shows a quasar composed of four narrow-band images together, which appears as a burred rainbow blotch of colors. Credit: ESA/Webb, NASA, CSA, D. Wylezalek, A. Vayner and the Q3D Team Webb Space Telescope Uncovers Dense Cosmic Knot in the Early Universe NASA’s Webb Space Telescope continues its search into the earliest times of our universe, revealing the surprising formation of a massive galaxy cluster…

Next-Generation Electrolytes for High Energy Density Lithium Metal Batteries

Lead Imager: The high reactivity of lithium metal reduces the electrolyte at its surface, thereby leading to the degradation of lithium metal battery performance. To overcome this issue, scientists have developed functional electrolytes and electrolyte additives to form a surface protective film, which impacts the safety and efficiency of lithium batteries, but this was still not efficient to prevent certain severe side reactions. In the current study, researchers stabilized the lithium metal and electrolyte by designing the electrolyte to provide upshifted oxidation-reduction potential of lithium metal, thus succeeding in weakening the reaction activity of lithium metal thermodynamically, which could help…

Study Finds New Health Benefits of Walnuts

Lead Image: Eating walnuts was also associated with less weight gain. Eating walnuts may reinforce favorable health effects such as improved diet quality and increased probability of physical activity. Researchers found that participants who ate walnuts early in life showed a greater likelihood of being more physically active, having a higher quality diet, and experiencing a better heart disease risk profile as they aged into middle adulthood after reviewing 20 years of diet history and 30 years of physical and clinical measurements. The National Heart, Lung, and Blood Institute of the National Institutes of Health funded the long-term and ongoing…

Even Moderate Exercise Can Greatly Increase Brain Size

Lead Image: According to the study, certain regions of the brain are bigger in physically active people than in less active people. The effects are more pronounced in brain areas with high oxygen demand. Exercise keeps both the body and the mind healthy, but little is known about how and where physical exercise impacts our brains. “In previous research, the brain was usually considered as a whole,” says Fabienne Fox, neuroscientist and lead author of the current study. “Our goal was to take a more detailed look at the brain and find out which regions of the brain physical activity…
