Your daily routine could have a bigger impact on your ability to handle stress than you realize. A Binghamton University study of approximately 400 college students found that eating breakfast regularly, exercising, sleeping well, and taking fish oil were associated with greater psychological flexibility, which helps people adapt to stressful situations. Poor sleep and unhealthy eating habits, me…

NASA’s James Webb Space Telescope has revealed an ancient galaxy cluster with an unexpectedly dense concentration of dark matter, challenging theories about how the universe developed. The discovery also uncovered a surprising connection between scattered starlight and invisible dark matter that could transform how astronomers study the early cosmos.

Scientists have uncovered a hidden layer of organization in the brain by creating the first detailed 3D map of its lipids, the fatty molecules essential for brain structure and communication. By analyzing millions of measurements from mouse brains, researchers identified 539 distinct chemical zones, revealing patterns and boundaries that traditional brain maps have missed. Surprisingly, even whit…

Scientists have discovered that the body's cellular recycling system behaves very differently during aging than previously believed, with higher activity sometimes linked to worse physical health. A small study suggests that even gentle exercise could help restore more youthful cellular recycling patterns in older adults.

Scientists have created a new coating for mitochondria that preserves their ability to produce energy, potentially opening the door to new treatments for diseases involving these tiny cellular powerhouses. The technology could one day help transfer healthy mitochondria into damaged cells, although its effectiveness in transplantation remains unproven.

A 165-million-year-old fossil has revealed an extraordinary Jurassic predator that may help explain how mammals developed one of their most important evolutionary advantages. Although only 20 inches long, Megacauda sungei was a heavyweight among early mammal relatives, swimming through ancient waterways and hunting prey with specialized teeth. Its advanced swallowing anatomy reveals an early step…

Scientists have uncovered a surprising hidden ability of light that allows it to develop spinning, twisting behavior as it travels through empty space, without special lenses, mirrors, or materials. Researchers discovered that light’s internal geometry can naturally produce left- and right-handed patterns, challenging long-standing assumptions about how light behaves. By carefully arranging a bea…

Scientists have developed a model showing that gut bacteria play a surprisingly important role in how many calories we absorb, meaning food labels may not tell the full story. In a controlled study, people eating a high-fiber diet absorbed about 116 fewer calories per day than those eating a typical Western diet, without feeling hungrier.

Excessive smartphone use may be taking a hidden toll on the brain and body, with heavy scrolling linked to poorer memory, reduced attention, disrupted sleep, and potential balance problems. Researchers found that weak self-control and fear of missing out, rather than personality alone, are key factors behind problematic phone use.

Scientists may have solved a 2.3-billion-year-old mystery about how Earth maintained enough oxygen to support life. Ancient rocks reveal that phosphorus recycling in the oceans created a self-sustaining cycle that helped keep oxygen levels high, even as the planet underwent dramatic environmental changes. The discovery challenges assumptions about Earth's early atmosphere and raises new questions…

Europe's Sentinel-3C satellite has returned breathtaking images of Earth just two weeks after launch, revealing the snowy Alps, frozen Arctic islands, and brilliant turquoise Caribbean waters. Its first measurements also show promising results for tracking rising seas, melting ice sheets, and other changes reshaping our planet.

Scientists have traced the development of a mouse embryo from its first two cells to the formation of organs, using a remarkable DNA recording system that reveals the family history of individual cells. Their findings uncover how different cell types emerge on their own schedules and could help explain what goes wrong in birth defects, genetic disorders, and cancer.

Oxford physicists have recreated a bizarre quantum effect in which a particle responds to a magnetic field without ever traveling through it. Using a hybrid quantum computer, they demonstrated how introducing a simulated magnetic flux could completely halt a particle's movement through quantum interference. The experiment brings a decades-old prediction into a new setting where matter and quantum…

The remarkable intelligence of octopuses, squid, and cuttlefish may trace back to an ancient reshuffling of their DNA that created new connections between genes. Scientists discovered that these changes in the genome's 3D structure may have helped drive the evolution of their unusually complex nervous systems.

Popular GLP-1 weight loss drugs, such as Ozempic and Wegovy, have been linked to unexpectedly high rates of nail detachment, hair loss, and scalp inflammation, with some problems occurring several times more frequently among users. Researchers found that weight loss alone could not fully explain the differences, suggesting there may be more to these overlooked symptoms.
