New drug helps immune system target liver cancer by blocking fat metabolism

Firefighters work hard saving lives, and in the process put their own lives at heightened risk from skin, kidney and other types of cancers, a new American Cancer Society (ACS) study finds.

Health officials have confirmed Wisconsin's first human case of West Nile virus in 2025.

From fetal stages through adolescence, the brain undergoes rapid, layered development—from basic motor skills to complex emotional regulation. Yet this very dynamism, coupled with children's physical and behavioral traits, makes brain imaging extraordinarily difficult. Common conditions like autism spectrum disorder (ASD), Attention-Deficit/Hyperactivity Disorder (ADHD), and perinatal brain injury often leave subtle but critical imprints on early neural architecture.

The "100 kettlebell swings a day" challenge is the latest viral fitness endeavor on social media. The challenge is simple: pick up a kettlebell and do 100 swings (bringing the kettlebell from between your legs and using your core and glutes to swing it up to chest or shoulder height) every day. These can be done either in one stint, or broken up throughout the day.

Children may be more likely to survive a rare, potentially fatal influenza complication if they receive rapid treatment for brain swelling and extreme immune responses, a Stanford Medicine-led report found.

Most U.S. adults have a "heart age" several years older than their chronological age—sometimes by more than a decade. And that gap is wider among men and among those with lower incomes or education or who identify as Black or Hispanic, according to a new study led by Northwestern Medicine.

A new study in Nature shows that delivering a single injection of gene therapy at birth may offer years-long protection against HIV, tapping into a critical window in early life that could reshape the fight against pediatric infections in high-risk regions.

A new study by investigators from Mass General Brigham examined the effects of policies banning flavored e-cigarettes on adults and young people. Investigators found that e-cigarette use significantly declined among young adults and adults in states that had enacted flavor bans relative to states that did not.

Researchers at the University of Colorado Anschutz Medical Campus, Montefiore Einstein Comprehensive Cancer Center (MECCC), and Utrecht University have found the first direct evidence that common respiratory infections, including COVID-19 and influenza, can awaken dormant breast cancer cells that have spread to the lungs, setting the stage for new metastatic tumors.

Parents are often told fruit is "bad" because it contains sugar, prompting concerns about how much fruit they should allow their child to eat.

The kids are not all right.

In late June, the Scientific Advisory Group for the Origins of Novel Pathogens (SAGO), a group of independent experts convened by the World Health Organization (WHO), published an assessment of the origins of COVID.

Have you ever wondered why people who nearly die often describe speeding toward supernatural light, or seeing their life flash before their eyes? You may have also heard about the powerful psychedelic dimethyltryptamine (DMT), a class A illegal drug in the UK, and how it might generate the so-called near-death experiences. In a recent study I compared both types of experience and found they share fascinating similarities—but also critical differences.

Modern dating is stressful enough, and that's even before you throw in premium subscriptions, ghosting and the unwritten rules of flirting. But for autistic people, there are even more variables to consider.

The COVID-19 pandemic has placed enormous pressure on health care systems and economies around the world, with particularly severe impacts on vulnerable groups like residents of long-term care facilities (LTCFs). One key lesson from the pandemic is that early detection and treatment can lower hospitalization and death rates while also cutting medical costs. Wastewater surveillance at treatment plants (WSTPs) has emerged as a low-cost and innovative method to detect outbreaks early. Many developed countries have adopted this approach, but Japan has been slow to do so.

Modern medicine is largely reactive—treating illness only after symptoms emerge. But a new study from the Research Institute of the McGill University Health Center (The Institute) and McGill University points to a more proactive future: one where silent signs of infection are detected before we even feel sick.

While federal food assistance cuts are too large to make up for in efficiencies, pooling resources among hunger relief agencies could help the remaining aid go further.

Green spaces boost mental health—especially in busy cities. A new study from Leiden and Stanford University reveals how nature benefits urban well-being and offers low-cost ways to make city life healthier for everyone.
