Millions of people are expected to lose access to Medicaid and Affordable Care Act marketplace health insurance plans if federal lawmakers approve the One Big Beautiful Bill Act, President Donald Trump's domestic policy package, which is now moving through the Senate.

In the fight against cancer, immunotherapy—which aims to boost the body's natural defenses against cancer—is experiencing remarkable growth. Most of these treatments are based on CD8 T lymphocytes, "killer cells" able to eliminate diseased cells. A team from the University of Geneva (UNIGE) has explored an alternative approach involving CD4 T lymphocytes.

Even small drops in national income can significantly increase the risk of various forms of childhood malnutrition—not only undernutrition but also overweight and obesity, shows a study led by the Barcelona Institute for Global Health (ISGlobal).

As public health insurance in the United States faces potential cuts, a Rutgers University review of medical records finds that Medicaid and Medicare patients with opioid addiction tend to receive behavioral health care services less often than those with other types of funding.

Following a heart transplant, patients must undergo surgical biopsies so that clinicians can monitor for signs of organ rejection. A new study shows the promise of a biomarker that could allow doctors to replace these invasive biopsies with a simple blood test. The results are published in the journal Transplantation.

President Donald Trump's One Big Beautiful Bill Act, sprawling legislation to extend his tax cuts and enact much of his domestic agenda, would require 40 states and the District of Columbia, all of which expanded Medicaid, to add a work requirement to the program.

California lawmakers are poised to delay the state's much-ballyhooed new law mandating in vitro fertilization insurance coverage for millions, set to take effect July 1. Gov. Gavin Newsom has asked lawmakers to push the implementation date to January 2026, leaving patients, insurers, and employers in limbo.

Learning to swim isn't just a childhood milestone—it's a life-saving skill, a confidence booster, and a path to lifelong health and joy.

For years after his service in Afghanistan and Iraq, U.S. Army Special Forces veteran Joe Hudak fought a daily battle against a voice inside his head screaming anxious, dark and dangerous thoughts.

As fired and retired scientists rallied outside in the Atlanta heat, an advisory panel that Robert F. Kennedy Jr. handpicked to replace experts he'd fired earlier, met inside the Centers for Disease Control and Prevention's headquarters to plan a more skeptical vaccine future.

A total of 27.2 million people of all ages were uninsured in 2024, marking a nonsignificant increase from 25.0 million in 2023, according to early estimates from the National Health Interview Survey, 2024, released by the National Center for Health Statistics.

New research from the University of Pittsburgh School of Medicine and La Jolla Institute for Immunology, published today in Nature Microbiology, reveals an opportunity for developing a therapy against cytomegalovirus (CMV), the leading infectious cause of birth defects in the United States.

In radiation therapy, precision can save lives. Oncologists must carefully map the size and location of a tumor before delivering high-dose radiation to destroy cancer cells while sparing healthy tissue. But this process, called tumor segmentation, is still done manually, takes time, varies between doctors—and can lead to critical tumor areas being overlooked.

A new study from scientists at the Buck Institute for Research on Aging has revealed a surprising player in the battle against Alzheimer's disease and other forms of dementia: brain sugar metabolism. Published in Nature Metabolism, the research uncovers how breaking down glycogen—a stored form of glucose—in neurons may protect the brain from toxic protein buildup and degeneration.

Studies show that the average attention span is now only eight seconds. That's about as much time as it takes to read a few sentences before being distracted.

A pioneering study has provided unprecedented insights into the immune response following pig-to-human kidney xenotransplantation. The findings, presented today at the ESOT Congress 2025, mark a significant step forward in overcoming the biggest challenge in xenotransplantation: rejection by the human immune system.

In the time before widespread vaccination, death often came early.

For years, researchers have seen a connection between exercise and the progression of cognitive disorders such as Alzheimer's—but ramping up movement isn't possible for many patients. A new study published in Nature Neuroscience looks at how to mimic those benefits without having to hit the gym.
