A randomized trial shows that administering cancer immunotherapy before 3pm can nearly double survival time for patients with non-small cell lung cancer. Researchers found significant benefits from aligning treatment with circadian rhythms during the initial cycles. This marks the strongest evidence yet for chronotherapy in oncology.

Researchers report that small doses of the antibiotic cephaloridine can prompt certain gut bacteria to increase production of colanic acid, a microbial polysaccharide previously tied to longer lifespan in laboratory animals. In experiments, treated roundworms lived longer and mice showed shifts in cholesterol or insulin measures associated with aging, with the team arguing the approach works by acting in the gut rather than throughout the body.

Researchers in Sweden and Norway have identified biological markers in the blood that signal the earliest stages of Parkinson's disease, potentially allowing detection up to 20 years before motor symptoms appear. The study, published in npj Parkinson's Disease, highlights a brief window where these markers are detectable, offering hope for earlier diagnosis and treatment. Blood tests based on this discovery could enter healthcare testing within five years.

Scientists have created innovative nanoparticles designed to destroy harmful proteins linked to dementia and cancer. These particles can access difficult tissues like the brain and precisely eliminate problematic proteins without broad side effects. The technology shows early promise for precision medicine.

A decades-long UK cohort study following 10,930 people born in 1970 found that children who showed more attention-deficit/hyperactivity disorder (ADHD) traits at age 10 had higher odds of multiple self-reported physical health conditions and physical health–related disability by age 46. The research, published in JAMA Network Open, suggests smoking, psychological distress and higher body mass index partly help explain the link, and highlights the need for better identification and support across adulthood.

A new study reveals that chemotherapy's damage to the gut lining unexpectedly rewires the microbiota, producing a compound that strengthens immune defenses against cancer spread. This process reduces immunosuppressive cells and enhances resistance to metastasis, particularly in the liver. Patient data links higher levels of this compound to improved survival in colorectal cancer cases.
