Threat-response in the brain's amygdala linked to sex-specific patterns of alcohol use

New research shows that the threat-response in the brain's amygdala (which processes emotions) is linked to different patterns of drinking by sex.

Targeting senescent fat cells provides new hope for ovarian cancer

Ovarian cancer is the most lethal malignancy of the female reproductive system. Due to its insidious early symptoms and the absence of specific screening modalities, approximately 70% of patients are diagnosed at an advanced stage.

Microneedle nanoparticle platform improves lymphatic imaging with high resolution

The lymphatic system plays a critical role in pathological conditions such as lymphedema and chronic inflammation to tumor metastasis, venous insufficiency, and impaired wound healing, making accurate evaluation of its structure and function increasingly important.

Researchers identify cellular changes in motor control following spinal injury

Even when people with incomplete spinal cord injuries can walk, everyday functions like standing, balancing or producing steady force may remain difficult. A new study shows why.

Natural peptide PEPITEM shows promise in reducing arthritic joint swelling

Scientists investigating the naturally occurring immunopeptide PEPITEM have shown reductions in arthritic joint swelling to a degree comparable to the current standard of care, and reduce the inflammatory changes that cause joint damage.

Stanford researchers create noninvasive way to deliver light deep inside the body

Light has an increasing number of applications in biology and medicine – it can be used to stimulate cell growth, manipulate neural signals, and treat some cancers – but it doesn't easily pass through tissue.

Moving more, sitting less, and sleeping well may lower dementia risk

Findings suggest that regular physical activity and adequate sleep may lower dementia risk, emphasizing the need for evidence-based lifestyle guidelines.

Lab study shows cigarette smoke damaged lung cells more than e-cigarette vapor

Researchers found that cigarette smoke extract disrupted the lung cell barrier, increased IL-6 inflammation, and caused DNA damage in Calu-3 cells, while e-cigarette vapor extract showed no significant adverse effects on these measures under the study conditions. The authors caution that these were in vitro findings using liquid extracts and unflavored e-liquid, so they do not directly predict long-term human health outcomes.

Dietitians report widely different strategies for FODMAP food reintroduction in IBS

A national survey of 145 registered dietitians found wide variation in how the low FODMAP diet’s reintroduction phase is delivered, especially in dosing, timing, sequencing, and follow-up. The findings suggest that clearer, evidence-based protocols could improve consistency while still allowing individualized care.

Rat hepatitis E virus may be a hidden cause of hepatitis in humans

This Nature Communications review argues that rat hepatitis E virus is an emerging zoonotic cause of hepatitis that is likely underdiagnosed because current tests are limited and awareness remains low. It shows that ratHEV is widespread in urban rodent populations, can infect humans and some other animals, and may spread mainly through indirect environmental exposure rather than direct rodent contact.

Researchers map how menstrual cycle phases affect athletic performance

In a repeated-measures study of 18 eumenorrheic female athletes, half-squat strength was highest in the late follicular phase and around ovulation, while handgrip strength peaked in the late luteal phase. Psychological measures also shifted across the cycle, with lower vigor and higher fatigue and depression scores in the late luteal phase, supporting more individualized training monitoring.

Nanodisc technology improves study of viral proteins for vaccines

Viruses are masters at invading our cells thanks to specialized proteins that coat their surfaces. When scientists design vaccines, they often create versions of these viral surface proteins to study how our immune systems might respond.

New target CD43 may improve leukemia immunotherapy outcomes

Macrophages, much like Alice of "Alice in Wonderland," recognize and consume tumor cells that display "eat me" surface markers.

Maternal signals help synchronize babies’ circadian rhythms before birth

Humans and most other organisms have internal biological clocks that track the daily cycle of sunrise and sunset. These clocks help time our sleep, metabolism and other essential body functions over the course of a day, creating daily patterns called circadian rhythms.
