Deep sleep brain activity helps mice resist social stress

Most adult sleep is non-rapid eye movement (REM), which is restorative and promotes resilience to stressful conditions. However, the brain mechanisms for non-REM sleep's relationship to stress resilience remain unclear.

Inhibitory neurons act as a brake on brain tumor growth

Brain tumors do not grow in isolation. They develop within the highly active environment of the brain, where neurons continuously exchange electrical and chemical signals.

Elusive stem cells offer clues to treat lumbar spinal stenosis

Researchers at Weill Cornell Medicine and Hospital for Special Surgery have discovered the stem cells—unspecialized cells that can develop into specific cell types—that give rise to the body's tendons and ligaments, the tissues connecting muscles and bones.

Patients' responses to oncologists can help predict survival in chronic lymphocytic leukemia

Patients' responses to questions routinely raised by oncologists may provide important clues about their chances of survival from chronic lymphocytic leukemia (CLL), according to a new study published in the journal Therapeutic Advances in Hematology.

Scientists traced a hidden immune route that may worsen tau-linked brain damage

In a mouse model of tauopathy, conventional type 1 dendritic cells (cDC1s) cross-presented brain-derived antigens in deep cervical lymph nodes, priming CD8+ T cells that accumulated in the brain and promoted neurodegeneration. Disrupting cDC1s or their cross-presentation activity reduced CD8+ T-cell infiltration and protected against neuronal loss, while human primary tauopathy samples also showed increased brain CD8+ T cells, although cDC1 involvement in humans remains unconfirmed.

Smoking linked to increased loneliness, study shows

Smoking is not social and leads to increased loneliness, according to a large Europe-wide study presented at the European Respiratory Society (ERS) Congress in Barcelona, Spain.

GLP-1 drugs appear psychiatrically safe, but one finding still raises questions

A systematic review of 11 observational studies representing more than 4.9 million patients found that GLP-1 receptor agonists were generally associated with neutral or potentially protective psychiatric outcomes, although one obesity-focused cohort reported increased risks of depression, anxiety, and suicidal behavior. Direct evidence for antidepressant effects remains limited, with only one cross-sectional study using validated mood scales and no randomized trials in the final synthesis, meaning causality cannot be established

Laughter therapy eases breathlessness in people with COPD

A clinical trial for patients with chronic obstructive pulmonary disease (COPD) shows that laughter therapy can reduce breathing difficulties and is as effective as more traditional breathing exercises. The research is presented at the European Respiratory Society (ERS) Congress in Barcelona, Spain.

AI chatbots wrongly reassure sleep apnea patients, study finds

In a third of cases, AI chatbots wrongly reassure sleep apnea patients that their symptoms are not serious, discouraging them from seeking a referral to a specialist, according to research presented at the European Respiratory Society (ERS) Congress in Barcelona, Spain.

Yoga with a cognitive twist showed some intriguing benefits in older adults

A 24-week pilot randomized trial found that both traditional Hatha yoga and a faster, cognitively demanding YogaCue program were associated with improvements in cognitive and physical performance in independently living older adults. YogaCue showed promising additional gains in verbal and episodic memory, aerobic fitness, and lower-body power, although the small study could not establish clear superiority over Hatha yoga across all outcomes.

Psilocybin protects sensory nerves from chemotherapy damage in preclinical study

In mouse models, prophylactic psilocybin prevented or reduced multiple features of chemotherapy-induced peripheral neuropathy, with cycle-matched dosing sustaining protection during repeated cisplatin exposure without measurably affecting tumor growth. Experiments in human-derived sensory neurons and ex vivo peripheral nerves linked the effect to 5-HT2A-dependent preservation of mitochondrial trafficking and local axonal energy supply, while a nonhallucinogenic 5-HT2A agonist reproduced protection against mechanical hypersensitivity.

Alcohol-free beer looks cheaper on the shelf, but the checkout tells a different story

A Great Britain analysis found that no/low-alcohol drinks were generally cheaper than regular-strength products on supermarket shelves and when equivalent products were compared directly. However, consumers paid more per serving for no/lo beer and about the same for cider, partly because these products were often sold in smaller, less cost-efficient packs.

What four pregnancy eating patterns revealed about mothers and newborns

Researchers analyzing 1,404 pregnant women in Germany identified four distinct dietary patterns that differed substantially in maternal BMI, socioeconomic status, age, and gestational weight gain. A vegetable-rich pattern was also associated with selected neonatal measures, including greater birth length, but most newborn associations were modest or nonsignificant, and the observational study cannot establish causality.
