Nerve-tumor interactions emerge as a transformative frontier in oncology

A new review article highlights a rapidly emerging frontier in oncology: the dynamic and influential relationship between nerves and tumors.

First-trimester protein intake linked to lower odds of small-for-gestational-age birth

A secondary analysis of 7,067 nulliparous participants found that first-trimester protein intake of 0.8 to less than 1.1 g/kg/day was associated with 22% lower adjusted odds of delivering an SGA infant than intake of at least 1.1 g/kg/day. The association was exploratory, with no dose-response pattern and no confirmation in sensitivity analyses.

New research highlights hidden metabolic risks in non-obese HIV patients

A new UC San Francisco study helps explain why people with HIV remain at elevated risk for type 2 diabetes despite effective suppression of the virus with modern medications.

Hidden microbes inside tumors reshape cancer immunity and treatment

A growing body of evidence is reshaping how cancer is understood, placing the spotlight on intra-tumoral microbiota as powerful yet previously overlooked players within the tumor microenvironment.

High-resolution scans reveal how depression affects hippocampal subfields

Researchers from the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have found that depression is associated with smaller volume in a specific part of the hippocampus, a brain region essential for learning and memory.

NEWS2 score may improve antibiotic decisions in suspected sepsis

A study of nearly 100,000 adults treated for suspected infection suggests that the National Early Warning Score (NEWS2), a score based on routinely collected vital signs that is widely used to identify patients at risk of clinical deterioration, may help clinicians identify which patients are most likely to benefit from immediate antibiotic treatment and which may safely undergo further evaluation before receiving antibiotics.

Galápagos wastewater is creating new reservoirs of antibiotic-resistant bacteria

Portable field surveillance reveals how untreated sewage is reshaping coastal microbial communities and spreading diverse resistance genes across one of the world’s most protected marine environments.

Experts call for better trials as IVF preparation techniques show unproven results

Preparation techniques used before embryo transfer, considered the most critical step in the IVF process, show no proven effect on pregnancy rates and remain inconclusive due to limited or low-quality data, a new Cochrane review finds.

Researchers map how blood cells cross into the brain during aging

The brain's immune system has long been thought to exist independently from the rest of the body, complete with its own specialized immune cells and a blood-brain barrier that limits what can travel into the brain.

Older men’s sexual priorities extend well beyond erectile function

A web-based survey of 6,000 Japanese men aged 50 or older found that sexual arousal was the function they most wanted to preserve, while erection became more highly valued as erectile function worsened. Erection showed the earliest age-related decline pattern, whereas ejaculation was the function most often reported as lost in older age.

New review highlights FOXA2's role in glucose regulation pathways

A newly published review highlights the pivotal role of FOXA2, a key transcription factor, in coordinating pancreatic development, maintaining islet cell identity, and regulating glucose homeostasis.

Healthy midlife habits linked to longer dementia-free years

Having normal blood pressure, no diabetes, and not smoking from age 48 to 68, are associated with nearly 13 additional years on average of dementia-free life, a new study shows.

Scientists combine imaging and phototherapy in a single tool against glioblastoma

Glioblastoma is the most aggressive form of brain cancer.

Cortisol may distort the body signals that guide risky choices in men

In a randomized study of 109 young adults, researchers measured cortisol responses, skin conductance signals, and risk-taking during the Iowa Gambling Task after an acute psychosocial stressor. Cortisol reactivity altered how anticipatory bodily signals related to risky choices in men, although the stress condition did not increase overall risk-taking.

GLP-1 drug tirzepatide associated with lower risk of major cardiovascular events

Adding the GLP-1 receptor agonist drug tirzepatide (marketed as Mounjaro) to standard care for patients with type 2 diabetes and heart disease is associated with a lower risk of a major cardiovascular event, such as a heart attack or stroke, finds a study published by The BMJ today.

Study reveals treatment gaps for atypical Alzheimer's disease patients

Many people with less common forms of Alzheimer's disease may not qualify for newer anti-amyloid treatments designed to slow the disease, according to a study published August 5, 2026, in Neurology®, the medical journal of the American Academy of Neurology.

Long-acting HIV prevention tools could help close the gap before a vaccine arrives

A review of non-vaccine HIV interventions highlights the strong preventive effects of long-acting PrEP, sustained ART, U=U, vertical transmission programs, and voluntary medical male circumcision. Gene editing and multispecific antibodies may expand future options, but safety, cost, access, adherence, and implementation barriers remain.

Neural stem cells split early into distinct neuron lineages

The cerebral cortex is densely packed with different nerve cells that enable us to perceive, think and act. Yet how these cell types arise while the brain develops is still not fully understood.

Telemedicine expands access to pediatric primary care for endocrine or behavioral health issues

A multi-institutional study led by researchers at Children's Hospital of Philadelphia (CHOP) found that telemedicine is becoming increasingly common for problem-based primary care, particularly for children with endocrine or behavioral health issues where chronic needs are significant.

Nerve-blocking therapy improves growth plate repair in injured bones

With the support of National Institutes of Health funding, Johns Hopkins Medicine investigators, led by pathologist Aaron W. James, M.D., Ph.D., previously discovered that sensory neurons in skeletal tissue are constantly sensing their environment and are quick to respond to injuries.
