Summer COVID surge continues as wastewater levels rise, CDC says

Vaginal health is tightly linked to the balance of bacteria in the microbiome, especially certain species of Lactobacillus. When this balance is disturbed—a condition known as dysbiosis—it can lead to increased risk of infections, complications during pregnancy, and other long-term health concerns.

In a recently published study, researchers at Fox Chase Cancer Center revealed for the first time that cancer cells can evade anti-cancer drugs by entering and surviving within bone marrow fibroblasts, a phenomenon they describe as "cell-in-cell." The study is published in the journal Blood Neoplasia.

Lasting only 100 days, though many acknowledge it continued much longer, the 1994 genocide against the Tutsi people in Rwanda is one of the most heinous genocides and mass murders in modern history. More than 100 million Rwandans are estimated to have been killed, while hundreds of thousands of women were sexually assaulted by militia.

UC Davis Health researchers have discovered that a natural molecule made by gut bacteria can reverse liver damage and repair the gut lining after aflatoxin exposure. The treatment may offer a new, non-toxic way to prevent and treat non-alcoholic fatty liver disease (NAFLD), a growing health problem affecting more than 1 in 4 adults in the U.S.

Cardiovascular diseases comprise a broad range of disorders affecting the heart and blood vessels, including myocardial infarction, stroke, coronary artery disease (CAD), hypertension, heart failure, and arrhythmias. These conditions remain the number one cause of death worldwide.

Adding a MET gene inhibitor enhances the effect of combined chemotherapy and immunotherapy in small cell lung cancer (SCLC), according to a multicenter study led by the Hospital del Mar Research Institute, in collaboration with researchers from the CIBERONC cancer research network.

In a new study, scientists have discovered more about how the body protects against dengue fever, one of the world's most common mosquito-borne illnesses, prompting hopes for more effective vaccines against the disease.

Electroretinography (ERG) is an ophthalmic diagnostic method used to determine whether the retina is functioning normally. It is widely employed for diagnosing hereditary retinal diseases or assessing retinal function decline.

Burnout and job dissatisfaction are likely to be key drivers influencing GPs' decisions to leave patient care within the next five years, University of Manchester researchers have found.

A Legionnaires' disease outbreak in Central Harlem has now sickened 90 people and caused three deaths, New York City health officials said Tuesday.

In a comprehensive study, researchers from the Department of Epidemiology at the Faculty of Medicine at the University of Augsburg have provided reliable evidence for a link between chronic inflammatory diseases and the development of tumors in the digestive tract. The results were recently published in eClinicalMedicine.

Healthy brain function relies on a steady supply of blood. Disruptions in blood flow are linked to major neurological conditions like stroke, Alzheimer's disease (AD), and traumatic brain injuries. But understanding how the brain fine-tunes this flow—especially across its smallest blood vessels—remains a challenge.

Rights activists in The Gambia are calling for justice after a one-month-old baby's death was linked to female genital mutilation, a widely practiced but illegal procedure up for review before the country's Supreme Court.

Stronger coordination between the brain and the stomach's natural rhythm is linked to higher levels of anxiety, depression, and stress, according to the largest study of its kind from Aarhus University.

What is long COVID? Despite hundreds of published studies and millions affected worldwide, the medical field still lacks a clear answer.

Princeton University and collaborators have developed SHINE-TB, a one-sample, parallelized reaction amplification and detection CRISPR assay that detects Mycobacterium tuberculosis directly from sputum, achieving 100% sensitivity (6 of 6) and 100% specificity (7 of 7) versus culture in 13 blinded clinical samples.

In the blistering heat of Freetown, Sierra Leone, young men gather on street corners, their limbs swollen, eyes glazed. They are the victims of kush, a cheap and deadly synthetic drug sweeping the country.

Around 1 in 5 women of childbearing age are living with [obesity], defined by the World Health Organization as having a body mass index (BMI) over 30 kg/m². Compared with women in the healthy BMI range (18.5–24.9 kg/m²), those living with obesity are three times more likely to experience fertility problems and nearly twice as likely to have a miscarriage. Many turn to in vitro fertilization (IVF) in the hope of having a baby.
