Lake fly larvae plunge more than 200 meters into Lake Malawi each day to hide from predators, using tiny air sacs to control their depth. A rubber-like material called resilin lets them expand or shrink the sacs by changing their pH. Their toughness challenges a popular explanation for why insects are absent from the open ocean.

Dreams are not random mental noise. A large study of more than 3,700 dream and waking reports found that what we experience during sleep is shaped by both our personalities and the world around us. Rather than simply replaying daily events, the dreaming brain mixes memories, emotions, imagined possibilities, and familiar settings into vivid new scenarios.

Unsweetened sparkling water may offer a tooth-friendlier alternative to sugary soda, according to a small preliminary study tracking how different drinks change mouth acidity. Soda caused the strongest and longest drop in salivary pH, while sparkling water produced only a temporary decline before saliva restored normal conditions. Importantly, acidity remained above the level associated with enamel damage.

Young Jupiter’s powerful magnetic field may have created a safe zone where several large moons could survive. Saturn lacked this protection, possibly explaining why Titan stands almost alone among its largest moons.

The offensive potential is no longer theoretical. We need to develop systems to strengthen public health as quickly as AI is accelerating biological designAs artificial intelligence rapidly transforms the biological sciences, it is pushing the future of biology in two opposing directions. AI can help bad actors generate recipes for biological weapons with just a few keystrokes and computational prompts. At the same time, AI can track disease outbreaks and deliver critical public health informati

Eating within a shorter daily window may help protect certain thinking skills as people age. In a small six-month trial, older women who limited eating to about 8 to 9 hours a day performed better on planning and problem-solving tests than those who ate over 12 hours. Both groups lost similar amounts of weight, hinting that when people eat could matter in addition to how much they eat.

A controlled mouse study has provided direct evidence that inherited genetics can steer how cancer begins and evolves after DNA damage. The discovery could eventually help doctors better predict cancer risk and tailor screening and treatments to each patient.

Prof Abbie Garrington reflects on an interview with the physicist Laura Grego about the battle for our skiesWhere are the arts and humanities in current debates about space research? The physicist Laura Grego tells us we “have to be aware of what is happening in space”, that we should probe Elon Musk’s potential “appropriation” of space via satellite, and that our spacefaring era raises questions about our stewardship of the Earth for future generations, and the significance of human culture (‘M

Preliminary study shows older people who avoided food four hours before bed did better in problem solving testsConfining mealtimes and snacks to a nine-hour window and avoiding food for four hours before bed may help stave off cognitive decline in older age, researchers say.A pilot study of older women living with overweight or obesity found hints of improvement in mental skills among those who ate within the restricted period compared with those who spread their meals over a longer time.

Giant sequoias are built to withstand ordinary fires, but recent extreme wildfires killed thousands of trees that had survived for centuries or even millennia. A new analysis of about 26,400 sequoias found that trees in areas treated with prescribed burns were nearly four times more likely to survive. Researchers estimate the controlled fires prevented about 1,900 deaths and could have saved thousands more if used across every grove.

Popular AI-powered food apps may make calorie counting easier, but they may also leave out a surprisingly large part of the meal. Four apps underestimated calories and fat by about one-third when tested against carefully prepared meals. High-fat ketogenic dishes appeared to cause the most trouble, while carbohydrates were measured more consistently.

Scientists discovered that damaged fat cells can become inflamed, lose their ability to store lipids, and eventually vanish, disrupting the body’s metabolism. The findings show that diabetes can result not only from excess fat, but also from losing the healthy fat tissue the body needs.
