President Donald Trump's "One Big Beautiful Bill" cuts federal spending on Medicaid and Affordable Care Act marketplaces by about $1 trillion over a decade, according to the nonpartisan Congressional Budget Office, threatening the physical and financial health of tens of millions of Americans.

As summer ushers in peak mosquito season, health and vector control officials are bracing for the possibility of another year of historic rates of dengue. And with climate change, the lack of an effective vaccine, and federal research cuts, they worry the disease will become endemic to a larger swath of North America.

While there is currently no cure for multiple sclerosis, researchers continue to discover clues to give a better understanding of how MS happens and how best to treat it.

Conversations allow humans to communicate their thoughts, feelings and ideas to others. This in turn enables them to learn new things, deepen their social connections, and co-operate with peers to solve specific tasks.

Inappropriate polypharmacy—the excessive or unnecessary use of multiple medications—is a major driver of emergency hospital admissions among adults aged 65 and over, according to a new study from the University of Bath in the UK.

Researchers have long focused on the STING (Stimulator of Interferon Genes) pathway as a way to harness the immune system's natural defenses against cancer. This pathway, which plays a key role in helping the body defend against potential pathogens, can be leveraged to trigger an innate immune response that targets cancer cells. However, a study published in the journal Nature Chemical Biology, led by biochemist Lingyin Li, is spearheading a new school of thought.

A research team has discovered that a specific group of neurons in the amygdala, a brain region involved in emotion regulation, plays a key role in the emergence of conditions such as anxiety, depression, and altered social behavior. This study, published in iScience, shows that restoring the neuronal excitability balance in a specific area of the amygdala is enough to reverse these behaviors in mice.

Kentucky has its first measles outbreak of 2025, as the U.S. case count sits just short of a 30-year high.

An Australian man has died from an "extremely rare" rabies-like infection transmitted by a bat bite, health officials said Thursday.

Bicycling is a great way to stay active and enjoy the outdoors. Whether you're a recreational rider or a daily commuter, it's important to protect your hands and wrists. Dr. Sanj Kakar, a Mayo Clinic orthopedic surgeon specializing in hands and wrists, shares practical tips to prevent injuries while biking.

Disrupted care during the COVID-19 pandemic led to sharp increases in other non-COVID causes of illness and death, particularly mental health disorders, malaria in young children, and stroke and heart disease in older adults, finds a study published by The BMJ.

Updated threshold values of preoperative serum calcitonin predict different extents of lymph node metastasis (LNM) in patients with medullary thyroid cancer (MTC), according to a study published in the August issue of JAMA Otolaryngology-Head & Neck Surgery.

Forensic pathologists play a unique role in monitoring and responding to public health threats and advancing our understanding of human disease and injury, according to a new review article published July 3 in The New England Journal of Medicine.

In 2021, Congress temporarily boosted the value of the Child Tax Credit (CTC) and expanded the maximum credit, for the first time, to families with no or little income. This policy change cut child poverty nearly in half. However, its expiration pushed many families with children back into poverty, reversing the gains the US pandemic-era policy achieved by helping low-income families meet basic needs.

As antibiotic-resistant "superbugs" make infections trickier to treat, some in the medical community are turning to bacteriophages for backup. Also known as phages, these viruses exclusively target bacteria, allowing them to tackle bacterial infections when introduced to a patient's body.

Researchers at McMaster University, Cleveland Clinic and Case Comprehensive Cancer Center have uncovered how a protein long associated with Alzheimer's disease helps lung cancer spread to the brain—a discovery that offers hope that existing Alzheimer's drugs could be repurposed in preventing cancer's spread.

A new study by scientists at the University of Colorado Anschutz Medical Campus reveals that joint tissue from patients with early-stage rheumatoid arthritis often have high levels of a protein called granzyme used by the immune system to attack pathogens.

Alcohol consumption is widely known to affect decision-making, but a recent study led by researchers from The University of Texas at El Paso found that the extent of that impact may have something to do with the drinker's gender.
