Inhaled insulin is effective for controlling blood sugar levels in children with diabetes, providing them with a faster-acting, needle-free option to manage their condition
The UK's health secretary has announced a 10-year plan to check newborns for a huge range of rare conditions. There are major medical and ethical issues with this, argues neurologist Suzanne O'Sullivan
Previous estimates have suggested that more than half of people who stop taking antidepressants experience withdrawal symptoms, but now a review of the evidence suggests this isn't the case, at least for short-term use.
Exercise seems to help prevent cancer and reduce the growth of tumours, and that protective effect may be due to the way working out changes the gut microbiome
Interest in the anti-parasitic drug ivermectin skyrocketed during the covid-19 pandemic, but evidence for many of its supposed health claims are lacking
Suddenly feeling old? Evidence now suggests that rather than a long, steady decline, we dramatically age around three specific times in our lives. Might it be possible to stay younger for longer?
The US Advisory Committee on Immunization Practices voted in June to stop recommending certain kinds of flu vaccines, a notable shift in vaccine guidance
Researchers in Australia have created a biodegradable gel that delivers Parkinson’s medications through a single weekly shot, replacing the need for multiple daily pills. Injected just under the skin, the gel steadily releases levodopa and carbidopa for seven days, helping keep tremors and stiffness in check while easing side effects linked to fluctuating doses.
Zebrafish can regenerate sensory hair cells that humans permanently lose, like those in the inner ear linked to hearing and balance. New research reveals two specific genes that control how different supporting cells in zebrafish divide and regenerate, offering clues to how mammals might someday tap into similar regenerative powers.
A massive spike in young children accidentally ingesting nicotine pouches has alarmed poison control researchers, with a 763% rise reported between 2020 and 2023. Unlike other nicotine products, these pouches have quickly become the most dangerous form ingested, often leading to hospital visits. Experts say appealing packaging and flavors are part of the problem and they're pushing for tougher safety measures, including childproof storage and flavor bans.
Movement helps your mood, but it's not one-size-fits-all. Exercising for fun, with friends, or in enjoyable settings brings greater mental health benefits than simply moving for chores or obligations. Researchers emphasize that context — who you're with, why you're exercising, and even the weather — can make or break the mood-boosting effects.
Postmenopausal women struggling with weight loss may find a powerful solution by combining the diabetes drug tirzepatide with menopause hormone therapy. A Mayo Clinic study revealed that this dual treatment led to significantly greater weight loss than tirzepatide alone. Women using both treatments lost 17% of their body weight on average, compared to 14% in those not using hormone therapy—and nearly half achieved dramatic 20%+ weight loss.
Aging men aren't just battling time—they're up against rising blood sugar. New research reveals that subtle increases in metabolic markers like glucose have more influence on declining sexual health than age or testosterone levels alone. The findings, based on a 6-year study of otherwise healthy men, show that even below-diabetes-level sugar changes can impair sperm mobility and erectile function. But there’s good news: lifestyle choices and medical support could help men maintain reproductive vitality well into older age.
In a striking new study, the anti-obesity drug tirzepatide, known as Mounjaro and Zepbound, not only triggered significant weight loss in obese mice but also slashed breast cancer tumor growth. The research, presented at ENDO 2025, links body fat reduction to better cancer outcomes, suggesting that these next-generation weight-loss drugs might offer unexpected benefits beyond metabolic health. With traditional dieting often falling short, this dual-action approach could reshape how doctors tackle obesity-related cancers.
For centuries, we’ve imagined Neanderthals as distant cousins — a separate species that vanished long ago. But thanks to AI-powered genetic research, scientists have revealed a far more entangled history. Modern humans and Neanderthals didn’t just cross paths; they repeatedly interbred, shared genes, and even merged populations over nearly 250,000 years. These revelations suggest that Neanderthals never truly disappeared — they were absorbed. Their legacy lives on in our DNA, reshaping our understanding of what it means to be human.
A cat named Pepper has once again helped scientists discover a new virus—this time a mysterious orthoreovirus found in a shrew. Researchers from the University of Florida, including virologist John Lednicky, identified this strain during unrelated testing and published its genome. Although once thought to be harmless, these viruses are increasingly linked to serious diseases in humans and animals. With previous discoveries also pointing to a pattern of viral emergence in wildlife, scientists stress the need for more surveillance—and Pepper remains an unlikely but reliable viral scout.
A surprising new study has uncovered over 200 misfolded proteins in the brains of aging rats with cognitive decline, beyond the infamous amyloid and tau plaques long blamed for Alzheimer’s. These shape-shifting proteins don’t clump into visible plaques, making them harder to detect but potentially just as harmful. Scientists believe these “stealth” molecules could evade the brain’s cleanup systems and quietly impair memory and brain function. The discovery opens a new frontier in understanding dementia and could lead to entirely new targets for treatment and prevention.
Adopting a physically active lifestyle at any stage of adulthood significantly lowers your risk of dying from any cause, especially from cardiovascular disease. A sweeping analysis of 85 studies confirms that those who stay active consistently reduce their mortality risk by 30–40%, while even those who become active later in life enjoy a 20–25% reduction.
Scientists at ETH Zurich have broken new ground by generating over 400 types of nerve cells from stem cells in the lab, far surpassing previous efforts that produced only a few dozen. By systematically experimenting with combinations of morphogens and gene regulators, the researchers replicated the vast diversity of neurons found in the human brain. This breakthrough holds major promise for studying neurological diseases like Alzheimer’s and Parkinson’s, creating more accurate models for drug testing, and eventually even enabling neuron replacement therapies.
Health and Human Services Secretary Robert F. Kennedy Jr. lambasted federal agencies he accused of being overly influenced by the pharmaceutical industry. But he and other “Make America Healthy Again” notables have their own financial ties to the vast and largely unregulated $6.3 trillion global wellness industry that ethicists say raise red flags.
Children and young adults in the U.S. foster care system suffer from mental health disorders and die by suicide at far higher rates than the general population, yet the system doesn’t uniformly screen and treat children who are at risk.
Even as states brace for significant reductions in federal Medicaid funding over the next decade, conservative legislatures across the country are passing laws that grant doula access to Medicaid beneficiaries.
The health industry couldn’t persuade GOP lawmakers to oppose big Medicaid cuts in President Donald Trump’s tax and spending bill for many reasons. A big one: Congressional Republicans were more worried about angering Trump than a backlash from hospitals and low-income constituents back home.
Billions in opioid settlement money was meant to be spent on treating and preventing addiction — but what happens if it’s misspent? Some advocates say attorneys general need to pay closer attention. If they don’t, a new tool might empower the public.
President Donald Trump’s big budget bill became his big budget law on July 4, codifying about $1 trillion in cuts to the Medicaid program. But the law includes many less-publicized provisions that could reshape the way the nation pays for and receives health care. Meanwhile, at the Department of Health and Human Services, uncertainty reigns as both staff and outside recipients of federal funds face cuts. Rachel Roubein of The Washington Post, Tami Luhby of CNN, and Rachel Cohrs Zhang of Bloomberg News join KFF Health News’ Julie Rovner to discuss these stories and more. Also this week, Rovner interviews KFF Health News’ Julie Appleby, who reported the latest KFF Health News’ “Bill of the Month” feature, about some very pricey childhood immunizations.
This installment of InvestigateTV and KFF Health News’ “Costly Care” series explores how the type of medical facility where a patient seeks care can affect the cost of that care — particularly when that facility is a hospital.
A Colorado bill banning surprise billing for ambulance rides passed unanimously in both legislative chambers, only to be met with a veto from the governor. As more states pass such legislation, some are hitting the same snag — concerns about raising premiums.
