Digestive issues more common during perimenopause and menopause, study finds

Inspired by tensions between health and financial well-being during the COVID-19 pandemic, a new model could significantly improve predictions of how disease will spread by acknowledging the trade-offs in a health crisis between public health and personal welfare.

Scientists at CSIRO, Australia's national science agency, have identified simpler and less invasive methods to improve Alzheimer's disease diagnosis, potentially making it easier for patients to access emerging treatments.

Scientists from the A*STAR Infectious Diseases Labs (A*STAR IDL) have uncovered a surprising mechanism showing how mosquito saliva can alter the human body's immune response during chikungunya virus (CHIKV) infection, contributing to Singapore's broader efforts to strengthen infectious disease preparedness.

In a city, coworking hubs bring people and ideas together. Inside cancer cells, similar hubs form—but instead of fueling progress, they supercharge disease. That's what researchers at the Texas A&M University Health Science Center (Texas A&M Health) have discovered inside the cells of a rare and aggressive kidney cancer.

A new study led by Rice University's Pernilla Wittung-Stafshede has revealed that protein clumps, or plaques that clog the brain, associated with Parkinson's disease are not merely waste; they can actively drain energy from brain cells. These clumps, composed of a protein called alpha-synuclein, were found to break down adenosine triphosphate (ATP), the molecule responsible for powering nearly all cellular activities.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive muscle wasting and limb paralysis. This neurodegenerative condition results from the gradual destruction of motor neurons, the nerve cells that control muscles.

Autoimmune diseases disproportionately affect women, with notable shifts in incidence following menopause, suggesting a potential role of sex hormones in immune regulation.

Many women during menopause complain about brain fog, which includes symptoms like forgetfulness, trouble concentrating, and mental fatigue, often due to fluctuating hormone levels. A literature review was conducted to examine published studies that explore the link between structural brain changes during menopause and cognitive, emotional and physiological outcomes.

Despite growing recognition of sex differences in traumatic brain injury (TBI) outcomes, the interaction between hormone transitions–particularly menopause–and brain injury remains significantly underexplored in both research and clinical care. A new study suggests a greater focus on hormone changes when diagnosing and treating TBIs in menopausal women.

Many symptoms, such as hot flashes and vaginal dryness, are commonly associated with the menopause transition. One of the lesser-known symptoms that worsens in midlife is dry eyes. A new study suggests that postmenopausal women exhibit a higher prevalence of dry eye disease than perimenopausal women.

Women are significantly more likely than men to develop Alzheimer's disease. Earlier age at menopause is associated with a greater risk for late-life cognitive decline and Alzheimer's disease. A new study suggests that this risk is even higher in women who carry the APOE e4 gene variant or who have systemic inflammation.

Anxiety is a common and significant symptom of menopause and perimenopause, largely due to hormone fluctuations. Numerous studies have focused on the potential benefits of hormone therapy in reducing anxiety. A new systematic review indicates the treatment does not consistently impact anxiety symptoms in midlife women. Results of the review were presented at the 2025 Annual Meeting of The Menopause Society in Orlando, held October 21–25.

Arc Institute, Gladstone Institutes, and University of California, San Francisco, scientists have developed an epigenetic editing platform that enables safe modification of multiple genes in primary human T cells, addressing a key manufacturing and scalability challenge in next-generation cell therapies.

A novel combination therapy pairing a DNA-synthesis inhibitor with a targeted radiopharmaceutical may improve outcomes for patients with advanced neuroendocrine tumors, according to new clinical trial data presented at the European Society for Medical Oncology (ESMO) Congress 2025.

While the expression "touch grass" is most often used as a meme to teasingly tell fellow internet users to log off and venture outside, there is research-backed evidence that reconnecting with sensory experiences only found in the physical world is highly beneficial for overall well-being.

A new study projects that US funding cuts to global health aid will have a catastrophic effect on pediatric TB, with children in Sub-Saharan Africa and Southeast Asia likely to experience a significant spike in preventable cases and deaths over the next decade—even by the most conservative estimates—unless funding is restored.

The fight against malaria has stalled after two decades of progress, with climate change and population growth among factors threatening a resurgence of the potentially fatal disease, campaigners said Tuesday.

The effects of physical activity don't stop when the movement does. In a new study published in the Proceedings of the National Academy of Sciences, Virginia Tech researchers, in collaboration with researchers at the University of Aberdeen and Shenzhen University, have found that being active adds to the total energy you use every day without causing the body to conserve energy in other ways.
