How do mammals manage to eat in situations that cause anxiety, step into exposed spaces, or slow down when anxiety drives them to keep moving? A new study pinpoints a leptin-sensitive circuit in the lateral hypothalamus that helps to overcome anxiety to perform essential behaviors such as exploring, feeding, and limiting maladaptive hyperactivity.

New research reveals that the number and complexity of cancer clinical trials since 2001 have varied across low- and middle-income countries (LMICs), with economic growth contributing to disparities, but only to a certain extent. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.

Researchers led by Dr. W. David Hill at the University of Edinburgh have identified a significant genetic correlation between childhood cognitive function and longevity, providing the first molecular genetic evidence that intelligence measured in youth shares genetic factors with lifespan.

Menopause may take a toll on women physically and emotionally due to declining estrogen levels. For some, the use of hormone therapy has proven valuable in managing bothersome menopause symptoms.

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.

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 cancer clinical trial by the ECOG-ACRIN Cancer Research Group (ECOG-ACRIN) shows that a drug that utilizes the body's immune system to target and eliminate cancer cells appeared to reduce the risk of distant metastases for an aggressive form of skin cancer when given immediately after surgery, but did not significantly reduce the overall risk of recurrence, which was a co-primary endpoint of the trial.

Melbourne researchers have discovered gender-affirming hormone therapy can alter body proteins to match a person's gender identity, potentially affecting susceptibility to certain health conditions.

A tiny wireless chip implanted in the back of the eye and a pair of high-tech glasses have partially restored vision to people with an advanced form of age-related macular degeneration. In a clinical trial led by Stanford Medicine researchers and international collaborators, 27 out of 32 participants had regained the ability to read a year after receiving the device.

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.

A new study led by researchers at Wake Forest University School of Medicine, in collaboration with the University of North Carolina at Chapel Hill and MD Anderson Cancer Center, has found that a direct-to-patient digital health program can significantly increase lung cancer screening rates among people at high risk.

A groundbreaking study published in Hypertension, the journal of the American Heart Association, has identified a set of blood-based biomarkers that can predict improvements in blood pressure five years after adolescents underwent metabolic bariatric surgery.

Sudden cardiac death is responsible for an unusually high proportion of deaths in female bodybuilders worldwide, according to research published in the European Heart Journal today (Tuesday).

The EndObesity Consortium’s narrative review underscores that most childhood obesity risks emerge in the first 1,000 days, well before birth, highlighting gaps in parental, social, and policy interventions. Effective prevention demands preconception-focused, family-wide, and system-level strategies built on equitable public health frameworks.

Researchers in Chicago found that both mothers and fathers consumed far less DHA and EPA than recommended, with lower maternal intake linked to prior preterm birth. Socioeconomic disadvantage and neighborhood opportunity also influenced omega-3 intake, highlighting disparities that affect family health potential.

Digital health tools such as apps, wearables, and web platforms can modestly improve children’s physical activity, diet, and weight outcomes. Shorter programs boost activity, while longer ones better support weight management, though effects on sleep and sedentary time remain unclear.

Chronic alcohol use accelerates Alzheimer’s disease (AD) progression by intensifying oxidative stress, neuroinflammation, and amyloid-tau pathology through shared molecular pathways. The review highlights emerging therapies, targeting TLR4, GSK-3β, and metabolic dysfunction, that may mitigate alcohol-induced neurodegeneration.

Research shows that more daytime movement in pregnant women with hyperglycemia can raise nighttime blood sugar, highlighting the need for further investigation.

The study uncovers links between neighborhood disadvantage and Alzheimer's biomarkers, stressing the importance of addressing social inequalities in healthcare.
