Breast cancer risk in younger women may be influenced by hormone therapy

For the first time, scientists have systematically studied the genetic effects of chemotherapy on healthy tissues.

A new study challenges the belief in a universal "pet effect" on human well-being. Using data collected during COVID-19 lockdowns, researchers found no significant change in respondents' well-being when they acquired or lost a pet in their household.

A UCSF analysis has found that the newer generation of much more effective diabetes medications are reaching only a fraction of the patients who are recommended to take them based on new guidelines.

For people recovering from substance use disorders, quitting smoking remains one of the most difficult—but most crucial—steps toward long-term health.

It's a debilitating disease that affects more than 500,000 Australians, but new research from the University of South Australia is offering fresh hope to people living with rheumatoid arthritis (RA).

While incidence and mortality rates for most cancer types have been on the decline in the United States, cases of uterine cancer increased an average of 0.7% each year between 2013 and 2022 and age-adjusted death rates increased 1.6% annually between 2014 and 2023, according to the Surveillance, Epidemiology, and End Results (SEER) Program at the National Cancer Institute (NCI).

Novel research has revealed that adolescent vaping of current delta-9-tetrahydrocannabinol (THC), cannabidiol (CBD), and synthetic cannabinoids (SCs) has increased between 2021 and 2023. Also, adolescents are increasingly unsure about the substances they vaped in their e-cigarettes.

The three most common reasons schools called emergency medical services (EMS) were for neurological crises such as seizures, psychiatric conditions or substance abuse, and trauma-related injuries, according to data from the national EMS registry analyzed by researchers from Ann & Robert H. Lurie Children's Hospital of Chicago.

Scientists have found that eating too much dairy could ruin your sleep. Researchers questioned more than 1,000 students about the quality of their sleep, their eating habits, and any perceived link between the two, and found a strong association between nightmares and lactose intolerance—potentially because gas or stomach pain during the night affects people's dreams.

A study presented at the 41st Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) reveals that women with polycystic ovary syndrome (PCOS) have distinct gut microbiota and metabolic signatures linked to premature endometrial aging and a higher risk of adverse pregnancy outcomes.

A brief research report evaluated obesity among U.S. children and adolescents from 2011 to August 2023 and compared changes before and during the COVID-19 pandemic.

Microscopic colitis (MC) is a chronic inflammatory bowel disease that severely reduces quality of life. MC is responsible for over 30% of all chronic diarrhea cases in people over 65 years of age, and its prevalence is rising worldwide.

Organ transplantation has significantly revolutionized the treatment of patients with organ failure. However, the recipient's immune system recognizes transplanted organs as foreign and elicits a defensive response that can lead to serious complications.

Oncologists utilizing artificial intelligence (AI) in their tests to spot pancreatic cancer at an early stage can also gain an overall picture of how the deadly disease is bound to develop, scientists from the University of Sharjah have revealed in a new study.

An international research team, including scientists from the Institut de Neurociències at the Universitat Autònoma de Barcelona (UAB), has developed a new solution to reduce the immune response triggered by neural prosthetics used after limb amputations or severe nerve injuries.

Sunglasses are an important accessory—not only for fashion, but more importantly, for protection. This summer, focus on wearing sunglasses while spending time outdoors. A Baylor College of Medicine ophthalmologist explains the benefits of sunglasses in the summertime and year-round.

Mouse models are central to drug development, including treatments for neurological disorders, such as Parkinson's disease. Such diseases often affect movement, and treatments may need to relieve symptoms such as tremors. To be able to model these diseases effectively in animal studies, we need to be able to track even the smallest of movements with accuracy and precision. Now, researchers at the Okinawa Institute of Science and Technology (OIST) have turned to Hollywood for inspiration.

With more than 1 in 10 Americans suffering from obstructive sleep apnea putting them at increased risk of heart problems and other health ills, a new study conducted by the University of Maryland School of Medicine (UMSOM) carefully analyzed the toll that this sleep disorder takes on U.S. active-duty military members, and their analysis was alarming.
