Salivary cortisol patterns predict cognitive decline in older adults

An irregular pattern and consistently higher levels of a stress hormone called cortisol found in the saliva were associated with cognitive decline later in life - Blacks specifically had lower overall cortisol levels and less change in their levels during the day than whites - according to newly published research.

Study identifies brain mechanism behind pregnancy-related food cravings

Why do food cravings become so strong during pregnancy? Researchers at LSU's Pennington Biomedical Research Center, in collaboration with colleagues, have identified a brain mechanism that may help explain how pregnancy changes the motivation to seek certain highly palatable foods.

New white paper calls for integrating oral and general healthcare

Oral health can no longer be treated separately from general health, according to a new white paper from the European Federation of Periodontology (EFP) and the European Association of Dental Public Health (EADPH) which calls for closer collaboration between dental, medical, public-health and social-care professionals.

Intracortical microstimulation: Evoking artificial perception and engaging plasticity-based modulation

But creating a long-lasting electronic connection with the brain is complicated. Conventional microwire and silicon electrodes are much stiffer than soft brain tissue.

New national guidelines developed to improve sepsis-related care

A UVA Health doctor and other leading national experts have developed important new guidelines to improve care for patients who develop sepsis, a dangerous full-body infection that kills at least 350,000 Americans every year.

Otolaryngologists gather to present latest advances in ear, nose, and throat care

The latest treatments and research advances in ear, nose, and throat care will take center stage in Los Angeles October 17-20, when more than 5,000 of the world's leading otolaryngologists gather for the 2026 Annual Meeting & OTO EXPO of the American Academy of Otolaryngology–Head and Neck Surgery Foundation.

New discovery overturns a prevailing model of brain development

For centuries, scientists have thought of the brain as a single, unified organ. But new research led by Stanford Medicine reveals that what we call the brain is two distinct organs that evolved independently over hundreds of millions of years.

Antibody therapy teaches the immune system to control HIV

There is no cure for HIV. While scientists have made considerable progress in controlling the infection, patients still must take daily antiretroviral medication for the rest of their lives.

Chronic stress and inflammation cause silent structural heart damage

Chronic stress from people's everyday lives may be causing lasting structural changes to the heart, harming health and reducing life expectancy.

Ultrasound stimulation reduces deep calf muscle stiffness to prevent injuries

Muscle strain injuries are a common problem in sports, and injuries to the triceps surae, the calf muscle group that includes the gastrocnemius and soleus, can significantly affect athletic performance and return to play.

Breast density clue for cancer risk

Women with a higher Body Mass Index in early adulthood may have a lower risk of developing breast cancer after the menopause because of lasting changes in the structure of their breast tissue, according to researchers at The University of Manchester and Manchester University NHS Foundation Trust.

Innovative synthetic artificial skin gives young double amputee his childhood back

A 12-year-old double amputee patient at Nottingham University Hospitals NHS Trust (NUH), who became only the second person in the US to receive a pioneering synthetic skin treatment for his limbs, was recently visited by the medical technology company that developed the product.

Transplanted human cortical organoids filled most of a mouse cortex. Then they began to connect

Researchers created xenocortical mice by transplanting human cortical organoids into animals genetically depleted of much of their native cortex, allowing the human tissue to occupy most of the available cortical space and form anatomical connections throughout the host nervous system. The grafts developed diverse cortical cell types, including L5-ET and VEN-like neurons, generated organized neural activity, and produced measurable cellular and behavioral responses to hypoxic injury.

Some food manufacturers could capture major nutrition and environmental gains by changing surprisingly few products

Researchers assessed the nutritional quality and environmental impacts of product portfolios from 44 major UK food and beverage manufacturers, covering 51.5% of the retail market. Their modelling showed that targeted changes to existing product lines could capture a substantial share of the potential nutrition and environmental gains for some manufacturers, although broader food-system changes would still be required to meet national and societal targets.

Better fitness was linked to healthier brain structure, but not better memory

Researchers studying 353 cognitively unimpaired adults aged 60 to 94 found that higher muscular capacity was associated with lower basal ganglia perivascular space volume, while greater aerobic fitness was associated with greater gray matter volume and medial temporal lobe thickness. Fitness was not directly associated with global cognition or episodic memory, and evidence for cognitive reserve was limited, although VO₂max explained additional variation in delayed verbal memory beyond tau burden.

Sex-specific biological clocks reveal how aging differs across the body in women and men

Researchers developed 38 sex-specific biological aging clocks across 15 organ systems, finding differences between females and males in genetic architecture, molecular signatures, disease associations, and mortality patterns. Brain aging clocks were linked to progression from mild cognitive impairment to Alzheimer’s disease in both sexes and to sex-dependent cognitive trajectories among solanezumab-treated A4 participants, while the authors stressed that sex-pooled and sex-interaction models remain complementary approaches.

Researchers mine cobra toxins to uncover a membrane-disrupting antimicrobial peptide

Researchers combined toxin sequence mining with machine learning and deep-learning prediction tools to identify and experimentally test 14 antimicrobial peptide candidates derived from cobra cardiotoxins. Most candidates showed limited antibacterial potency, while CTX-p5 displayed moderate membrane-disrupting activity, revealing both the potential and current limitations of computationally guided venom peptide discovery.

Scientists reveals how cancer-causing p53 mutations remain invisible to the immune system

One of the biggest challenges in cancer immunotherapy may not be that immune cells are too weak, but that some tumors give them too little to see.

Celastrol reduces cholestatic liver injury by inhibiting specific protein

Cholestasis occurs when bile formation, secretion, or flow is impaired, causing toxic bile acids to accumulate and trigger inflammation and liver-cell damage.
