Why might a higher BMI at 20 be linked to lower breast cancer risk later in life?

A large UK cohort study found that higher BMI at age 20 was associated with lower postmenopausal breast cancer risk, while higher BMI in later adulthood was linked to increased risk. Lower VAS percentage mammographic density appeared to explain part of the early-adulthood association, while fibroglandular volume showed a different relationship with life-course adiposity.

Scientists discover metabolite fueling aggressive brain tumor growth

Virtually all high-grade, aggressive gliomas in adults accumulate massive amounts of a metabolite called guanidinoacetate (GAA) that overstimulates nearby neurons and promotes tumor growth, according to new research from scientists at Children’s Medical Center Research Institute at UT Southwestern (CRI) published in Cell.

Immunotherapy combined with BCG vaccine drastically lowers tuberculosis relapse risk

Tuberculosis (TB) remains one of the world's leading causes of death, and preventing post-treatment relapse continues to be a major worldwide health challenge.

Shatavari may affect more than hormones, and the gut could help explain why

A review in Nutrients examined how bioactive compounds in Asparagus racemosus (Shatavari) may influence cognitive health through the microbiota-gut-brain axis, estrogen-related signaling, neuroinflammation, oxidative stress, and neurotransmitter regulation. Evidence from computational, cellular, animal, and limited human studies suggests several plausible biological pathways, but key questions remain about bioavailability, brain exposure, dosing, and clinical efficacy.

Cannabis-derived nanovesicles showed early antitumor potential in mice

Researchers developed a Cannabis sativa hairy root culture system that produced stable plant-derived nanovesicles capable of promoting dendritic cell maturation and activating T-cell responses through TLR2- and TLR4-associated signaling. Oral administration also restored selected immune responses in immunosuppressed mice and suppressed tumor growth in an E.G7 lymphoma model, providing preliminary evidence for their immunomodulatory and antitumor potential.

Aging brain actively shapes biology and progression of tumors

Brain tumors develop within an organ that changes substantially with age. A new review in Ageing and Cancer Research & Treatment examines evidence that the aging brain microenvironment may influence brain tumor progression, treatment resistance, and cognitive outcomes.

Technological roadmap proposed for lifetime brain-wide neural recordings

Understanding the brain requires tools that can follow neural activity across many scales: from millisecond electrical spikes in individual neurons to brain-wide circuit dynamics that change over months, years, and even a lifetime.

Two collagen receptors cooperate to enhance cranial bone regeneration

Bone repair depends on skeletal progenitor cells (SPCs) moving to injured areas and developing into bone-forming cells, but how these cells respond to their surroundings remains unclear.

Advancing intracellular delivery with LumiPore®: A new approach to cell transfection and drug discovery

Discover how LumiPore improves intracellular delivery with gentle, high-efficiency transfection for drug discovery and cell therapy research.

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.

Blocking a naturally occurring molecule reverses deadly lung disease in preclinical models

Researchers blocked a naturally occurring molecule to reverse pulmonary arterial hypertension in preclinical models, a finding that could point to a new treatment approach for people with a rare and often fatal lung disease.

Study reveals how melanoma weakens skin cell immune defenses

Cancers actively remodel their surrounding cells and tissues to create a microenvironment that favors their growth, survival, and spread.

Cell proliferation gene plays a distinct role in cells that no longer proliferate

In a tale of identities as divergent as "The Prince and the Pauper," a well-known cancer-causing gene also influences cells in a zombie-like state meant to prevent cancer.

Faulty myelin-making brain cells may help drive cognitive decline with age

Researchers found that greater age-related cognitive decline was associated with more dysfunctional oligodendrocytes, reduced NRF2 expression, smaller myelinated axons, and abnormally thicker myelin in human white matter. Experiments in mice showed that deleting NRF2 specifically from oligodendrocytes reproduced key white matter abnormalities and reduced cognitive improvement over time, implicating this pathway in cognitive aging.

From caffeine to trigonelline, coffee has surprising links to muscle biology

A scoping review of 54 studies found that coffee and several coffee-derived bioactive compounds influence pathways linked to skeletal muscle metabolism, including insulin signaling, mitochondrial function, oxidative stress, inflammation, glucose uptake, and protein turnover. Human studies reported associations with greater muscle mass and lower frailty or functional impairment, but most evidence remains observational or preclinical and cannot establish causality.

Tick-borne alpha-gal syndrome poses potential risks during blood transfusions

A new multi-institute study led by researchers at Dartmouth Health and Geisel School of Medicine at Dartmouth suggests that alpha-gal syndrome, the tick-borne disease that can result in a chronic allergy to meat and animal byproducts, also may complicate certain patients' ability to safely receive a blood plasma or platelet transfusion.

Scientists uncover safer way to tame cancer cell senescence

Stopping tumor growth is only half the battle. Rather than kill tumor cells, many cancer therapies can only push them into cellular senescence, a state in which cells stop dividing but do not die. These "undead" cells will continue to release signals that reshape the tumor environment.

Immune signaling pathway protects newborn heart cells from injury

Researchers at the University Hospital of Bonn (UKB) and the University of Bonn have identified a previously unknown signaling pathway in the immune system that helps newborn heart cells survive and regenerate after injury.

Superstorm Sandy reshaped indoor fungal communities, with an unexpected asthma result

and lower fungal diversity than non-damaged homes. Despite these persistent but variable fungal changes, researchers found no statistically significant increase in asthma morbidity, impaired lung function, or airway inflammation among children with relatively mild asthma.

Swimming sends wrist-worn heart rate monitors off track

Researchers created an open-access dataset comparing two wrist-worn heart rate monitors with a chest-strap reference during dry-land exercise and swimming. Both smartwatches performed substantially worse underwater, highlighting the challenges water poses to optical heart rate monitoring and providing a resource for future research on aquatic wearables.
