Nearly 30,000 people tested quit-smoking methods. One stood out

Nicotine e-cigarettes appear to help more smokers quit than patches, gum, and several other common approaches, according to a major review of 80 clinical trials. Researchers say regulated vaping products are not risk-free, but may be a significantly less harmful alternative for people who would otherwise continue smoking.

Just 7 days of strength training started shrinking fat cells in mice

Just seven strength-training sessions helped obese mice shrink visceral fat cells and reactivate molecular pathways involved in burning stored fat, despite no change in overall body weight. The findings suggest some benefits of resistance exercise may begin long before weight loss becomes visible, though the results still need to be confirmed in humans.

Stanford scientists turn a cancer driver into a kill switch

A Stanford-designed molecule turns a major lymphoma-promoting protein against cancer cells, activating their own self-destruct machinery instead of simply blocking tumor growth. In mice, the treatment completely eliminated aggressive human lymphoma tumors within 11 days, although much more testing is needed before it could reach patients.

Drug target could block brain inflammation linked to Alzheimer’s and Parkinson’s

Blocking a receptor called P2X7 significantly reduced inflammation in human brain tissue, revealing a potential new treatment strategy for neurological and psychiatric disorders. The discovery could help researchers repurpose existing drugs for conditions including traumatic brain injury, Alzheimer’s, Parkinson’s, depression, and schizophrenia.

A few drops of this Japanese tree oil may help you sleep more soundly

In a small study, sleeping near the scent of Hinoki root essential oil was linked to fewer nighttime awakenings, better morning alertness, and brain-wave changes associated with smoother sleep onset. The findings suggest an overlooked forestry byproduct could someday become a natural ingredient in sleep and relaxation products.

Cancer-fighting t cells burn out. Scientists may have found a fix

Cancer immunotherapy can lose its punch when tumor-fighting T cells become exhausted, but researchers may have found a way to keep them going longer. Scientists at Memorial Sloan Kettering Cancer Center identified a signaling molecule called MEK that can push T cells to burn through their energy while producing cancer-killing proteins. In animal and laboratory studies, blocking MEK helped the cells conserve energy, survive longer, and remain active even in the harsh environment around tumors.

Vitamin D drug may help crack pancreatic cancer’s protective shield

A vitamin D analog may help break down pancreatic cancer’s protective defenses, potentially making tumors more vulnerable to chemotherapy and immune attack. A small clinical trial found encouraging responses, especially in patients whose tumors had high levels of the vitamin D receptor.

Scientists may have found a “unifying theory” of chronic fatigue

Scientists found that five seemingly unrelated conditions, including long Covid, ME/CFS, and PTSD, may disrupt many of the same biological networks involved in immunity, metabolism, and cellular energy. The findings could help explain their shared symptoms and may open the door to new blood tests and treatments.

This common mistake can add nearly 7 points to your blood pressure reading

A common mistake during blood pressure checks could make readings appear substantially higher than they really are. Johns Hopkins researchers found that leaving the arm unsupported can raise systolic readings by about 6.5 mmHg, potentially affecting a hypertension diagnosis.

Forget LASIK: Safer, cheaper vision correction without lasers or incisions

Scientists are developing a possible alternative to LASIK that reshapes the cornea without cutting it or using a laser. The technique uses a small electric potential and a specially shaped platinum lens to temporarily soften the cornea, allowing it to be molded in about a minute.
