Immersing stressed volunteers in a 360° virtual Douglas-fir forest complete with sights, sounds and scents boosted their mood, sharpened short-term memory and deepened their feeling of nature-connectedness—especially when all three senses were engaged. Researchers suggest such multisensory VR “forest baths” could brighten clinics, waiting rooms and dense city spaces, offering a potent mental refresh where real greenery is scarce.

A group of scientists studying pregnancy across six different mammals—from humans to marsupials—uncovered how certain cells at the mother-baby boundary have been working together for over 100 million years. By mapping gene activity in these cells, they found that pregnancy isn’t just a battle between mother and fetus, but often a carefully coordinated partnership. These ancient cell interactions, including hormone production and nutrient sharing, evolved to support longer, more complex pregnancies and may help explain why human pregnancy works the way it does today.

Scientists have captured the moment a laser “comes to life”—and what they found challenges long-held beliefs. Using a special technique to film laser light in real time, researchers observed how multiple pulses grow and organize themselves into a stable rhythm. Instead of one pulse splitting into many (as previously thought), these pulses are amplified and evolve through five fast-paced phases, from initial chaos to perfect synchronization. This discovery not only deepens our understanding of how lasers work but could also lead to sharper, faster technologies in communication, measurement, and manufacturing.

Scientists have pioneered a new way to monitor sodium levels in the blood—without drawing a single drop. By combining terahertz radiation and optoacoustic detection, they created a non-invasive system that tracks sodium in real time, even through skin. The approach bypasses traditional barriers like water interference and opens up potential for fast, safe diagnostics in humans.

Deep in Chile’s Atacama Desert, scientists studied a green crystal called atacamite—and discovered it can cool itself dramatically when placed in a magnetic field. Unlike a regular fridge, this effect doesn’t rely on gases or compressors. Instead, it’s tied to the crystal’s unusual inner structure, where tiny magnetic forces get tangled in a kind of “frustration.” When those tangled forces are disrupted by magnetism, the crystal suddenly drops in temperature. It’s a strange, natural trick that could someday help us build greener, more efficient ways to cool things.

Scientists at the University of Sydney have uncovered a malfunctioning version of the SOD1 protein that clumps inside brain cells and fuels Parkinson’s disease. In mouse models, restoring the protein’s function with a targeted copper supplement dramatically rescued movement, hinting at a future therapy that could slow or halt the disease in people.

These findings highlight the significance of rearing behavior and behavioral lateralization as potential behavioral markers for tracking the progression of Parkinson’s disease.

People who treat hearing loss with hearing aids or cochlear implants regain rich conversations, escape isolation, and may even protect their brains and lifespans—proof that better hearing translates into fuller living.

In the latest attack on science by the Trump administration, researchers at the National Snow and Ice Data Center will no longer receive data from a fleet of military satellites.

In principle, this impossible math allows for a glue-free bridge of stacked blocks that can stretch across the Grand Canyon—and into infinity
