After a heart attack, the body rapidly floods the injured heart with neutrophils - white blood cells that help repair damage but can also make it worse when too many arrive too quickly.

Despite recent government guidelines that parents should avoid screen time for babies under the age of two, a new global study finds that one in ten babies now regularly fall asleep with a screen.

Akkermansia muciniphila's impact on immunity and pregnancy outcomes underscores its promise as a probiotic, with implications for infectious disease treatment.

Public health experts estimate that more than 200 million people worldwide are exposed to arsenic through contaminated drinking water. Scientists know long-term exposure to arsenic is associated with increased risk of chronic illnesses like cancer and cardiovascular disease, but there hasn't been a reliable way to track these exposures and fully understand their effects on the body and the mechanisms behind them.

Weill Cornell Medicine investigators have "reverse engineered" ketamine's antidepressant effects to identify potential new strategies for treating depression.

Research identifies distinct dietary patterns in older adults, revealing how nutrition impacts health outcomes and food security among this vulnerable group.

A University of California, Riverside study reports that cells in the earliest stages of human development could be susceptible to infection by SARS-CoV-2, which causes COVID-19, offering new insight into how the virus interacts with developing human tissues and why that may matter for pregnancy research.

Aplastic anemia is a rare, life-threatening blood disorder where patients are unable to make enough blood cells due to the immune system's attack on blood stem cells. The condition can progress to myelodysplastic syndrome (MDS) and leukemia. A study led by scientists at St. Jude Children's Research Hospital, with multiple collaborating institutions, used state-of-the-art genomic techniques to profile 619 children and adults with aplastic anemia.

Sickle cell disease (SCD) is the most common inherited blood disorder in the United States. Approximately 10 percent of people with SCD in the US live in New York State, with the majority residing in New York City.

The research, published on April 24th, 2026, in Nature Microbiology, describes how the new tool, called TRAnsmision Clustering of Strains (TRACS), uses genomics to distinguish between closely related bacterial strains.

People with obesity face a significantly increased risk of atherosclerosis, and consequently heart attack and stroke.

Following the rise in monkeypox (Mpox) cases, particularly in countries where the disease had not traditionally been observed, the World Health Organization (WHO) declared a Public Health Emergency of International Concern in June 2022 and again in August 2024.

Endothelial dysfunction is a hallmark of cardiovascular disease (CVD) and plays a central role in vascular inflammation, thrombosis, and impaired vasodilation.

Research indicates semaglutide can significantly decrease alcohol consumption and cravings in individuals with comorbid obesity and alcohol use disorder.

Total hip arthroplasty leads to the best outcomes in the treatment of moderate-to-severe hip osteoarthritis, according to a new study by the University of Eastern Finland and Kuopio University Hospital. During a one-year follow-up, surgery combined with conservative treatment was found to relieve pain and improve functional capacity and quality of life more effectively than conservative treatment alone, which was based on an exercise program.

Blood tests measuring the aging of certain white blood cells can predict cognitive and mood-related symptoms of depression, rather than physical symptoms.

Low doses of the investigational medicinal product endoxifen reduce breast density to the same extent as the standard treatment tamoxifen, but without causing such troublesome side effects. This is shown by a new study from Karolinska Institutet published in the Journal of the National Cancer Institute. The results may have implications for future preventive treatment of breast cancer.

Diaceutics, the intelligence and engagement company unlocking the full potential of diagnostic-driven therapies, has released new research revealing a critical shift in precision medicine. Despite major advances in biomarker testing, nearly two-thirds of eligible patients with advanced non-small cell lung cancer (aNSCLC) in the US are still not receiving the most appropriate treatment

The American Academy of Dermatology (AAD) today released results from its annual Practice Safe Sun Survey, revealing many Americans still engage in risky sun behaviors driven by misinformation, social media, and persistent tanning myths despite their concerns about the long term aging effects of sun exposure. In recognition of Skin Cancer Awareness Month (May) and Melanoma Monday® on May 4, the AAD is encouraging the public to practice safe sun to reduce their risk of skin cancer.

New research identifies critical ages for Alzheimer's biomarkers, enhancing screening strategies and understanding neurodegeneration across the aging spectrum.
