Tumors exploit peripheral nerves to support cancer growth and spread
Tumors do not communicate only with immune cells, blood vessels, and stromal tissue. A growing body of evidence suggests that cancer can also co-opt the nervous system, reshaping the tumor microenvironment in ways that support growth, invasion, immune escape, and therapeutic resistance.

Non-invasive swab test offers fast, accurate tuberculosis detection worldwide
A portable molecular test, MiniDock MTB, detected pulmonary tuberculosis rapidly and accurately across seven high-burden countries, using sputum or tongue swab samples. The study suggests the low-cost, battery-operated platform could expand near-point-of-care TB diagnosis in low-resource settings, although real-world implementation and drug-resistance integration still need evaluation.

Do repeated football head hits disrupt the gut microbiome?
A small exploratory study of collegiate football players found that non-concussive head impacts are correlationally linked to acute and season-long shifts in gut microbiome composition, with changes most pronounced 48–72 hours after significant impacts. However, most associations weakened after correction for multiple testing, and the authors stress the findings are preliminary and hypothesis-generating.

What drives adult ADHD symptoms? Study points to executive function over environment
Adults diagnosed with ADHD later in life had fewer childhood symptoms than those diagnosed in childhood, but both groups showed similar symptom severity in adulthood. Executive function, rather than childhood trauma, resilience, or parental bonding, was the strongest correlate of current ADHD symptoms across both diagnostic-history groups.

Liver fat may disrupt post-meal glucagon control in early type 2 diabetes
Researchers found that MASLD, rather than type 2 diabetes alone, was linked to higher fasting glucagon levels in adults with newly diagnosed diabetes and matched controls. In people with early type 2 diabetes, higher liver fat was specifically associated with exaggerated early post-meal glucagon responses, independent of insulin sensitivity, visceral fat, amino acids, or NEFAs.

Autistic people gain measurable police-interaction skills after short VR training
A randomized controlled trial found that Floreo’s virtual reality Police Safety Module helped autistic teens and adults reduce fidgeting during live police-interaction assessments compared with video-based BeSAFE training. Both groups reported greater knowledge and comfort after training, but the clearest behavioral gains were seen in the VR group, supporting immersive practice as a promising tool for safer police encounters.

Lab-grown diamonds enable highly-sensitive radiation dose measurements
A team led by researchers from Tokyo Metropolitan University, in collaboration with Tohoku University and Orbray Co., Ltd., using heteroepitaxial diamond materials developed by Orbray, have shown that lab-grown diamonds might realize a radiation dosimeter compatible with both medical diagnosis and radiation therapy.
