- newWhat if the brain does not create consciousness?
Christof Koch is taking on one of science’s deepest mysteries: how the brain creates conscious experience, or whether it creates it at all. He argues that materialism has yet to solve this “hard problem” and will explore puzzling phenomena such as near-death experiences and terminal lucidity. His work points toward the possibility that consciousness may be woven into reality itself.

- newRice bran compound may help ease irritable bowel symptoms
A compound in rice bran may help calm an overactive gut by reducing the calcium signals that cause intestinal muscles to contract. Ferulic acid suppressed contractions triggered by several chemical messengers in laboratory experiments. The discovery could eventually support new dietary approaches for diarrhea-related digestive disorders, although it may make constipation worse.

- Daily multivitamin may help older adults stay independent
Taking a daily multivitamin may help older adults preserve the strength and stamina needed for everyday activities. After three years, users reported better functional health than those taking a placebo, although the preliminary findings still require peer review.

- Scientists find a simple way to stop cavities without drilling
A liquid brushed onto cavities in seconds may spare many young children from pain, infection, and surgery. A major U.S. trial found that silver diamine fluoride stopped decay in more than half of treated baby teeth. The treatment requires no drilling, shots, or sedation, although it does permanently darken the decayed area.

- Your gut may help your brain decide what to remember
Signals traveling from the gut to the brain may help turn meals into lasting memories. Rats showed stronger memory activity after consuming nutritious foods, but not after drinking sweet liquids with little or no nutritional value. Blocking the vagus nerve erased this effect and made it harder for the animals to remember where food had been located. Over time, diets high in fat and sugar also weakened this memory system.

- New microwave frying method could make french fries much healthier
A new cooking method could make French fries crispier in less time while significantly limiting how much oil they absorb. Researchers propose combining microwave heating, which keeps oil out, with conventional frying, which provides the crunch consumers expect.

- Can’t sleep in the heat? These 8 tricks could save your night
Sleeping well during a heatwave starts with stopping the home from overheating. Close blinds against strong sunlight, ventilate when the air outside becomes cooler, and avoid using heat-producing appliances during the hottest hours. Moving to a cooler room, choosing light bedding and using fans or ice packs safely can also make hot nights more manageable.

- 4 in 5 toddler foods are ultra-processed
A grocery-store audit found that many foods marketed for toddlers may be far less healthy than parents expect. Of nearly 2,800 products examined in Texas, 81% were ultra-processed, and almost half failed at least one World Health Organization nutrient standard, often because they contained too much sugar, sodium, fat, or too many calories.

- Misfolded insulin may be quietly driving diabetes
Researchers found that insulin-producing cells depend on a team of helper proteins to keep insulin production on track. When one key partner was missing, damaged proteins built up and the cells made less insulin. Strengthening this system could offer a new way to protect the pancreas as diabetes progresses.

- Why losing weight may not be enough to prevent type 2 diabetes
A healthy lifestyle can prevent type 2 diabetes for many people, but new research suggests that weight loss alone may not be enough for one particularly vulnerable group. Even after losing about 8% of their body weight and keeping it off for years, people in a high-risk category known as cluster 5 continued to experience rising blood sugar, weakening insulin production, and a strong risk of developing diabetes.

- Exercise may not help hip arthritis as much as patients expect
A major review found that exercise produces only small average improvements in hip osteoarthritis pain and physical function. It may still help some people, but researchers warn that current evidence is too limited to know which exercises work best.

- A single sauna session sends immune cells surging
A single 30-minute sauna session may briefly put the immune system on higher alert. Finnish researchers found that sauna heat, paired with a short cold shower, increased every type of white blood cell circulating in the bloodstream, including key infection fighters such as neutrophils and lymphocytes.

- Your dreams aren’t random. Your brain is rewriting reality
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.

- Scientists reveal what sparkling water really does to your teeth
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.

- Eating within 8 hours may help keep the aging brain sharp
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.
