From infections to brain injuries, the female body is more resilient than the male. It is time to reassess the "weaker" sex, says Cat Bohannon
A single dose of genetically engineered immune cells reduced asthma symptoms in mice for at least a year
Mice that were given a high dose of the antiviral drug oseltamivir phosphate, better known as Tamiflu, after prolonged and excessive noise exposure showed fewer signs of hearing loss compared with those not given the medication
Male mice injected with a molecule that affects sperm movement were temporarily unable to impregnate a female, showing promise for a new type of birth control drug for people
New survey data estimates that 7.1 million children in the US have been diagnosed with ADHD at some point, about 1 million more kids than had been diagnosed as of 2016
New proposals for addictions seem to keep cropping up, but the reality is we don't truly understand the mechanisms behind our cravings in the first place
People with higher genetic risk for depression, schizophrenia and bipolar disorder are more likely to have unusual activity levels of "fossil viruses" in their genomes
The largest study yet looking at whether conditions such as depression and anxiety could spread between teenagers finds that one person in a class being diagnosed is linked with a higher risk for their classmates
Researchers have come to see cancers as akin to organisms, existing in complex ecosystems and subject to evolutionary pressures. Now they are targeting cancer’s ability to adapt
Early evidence suggests that a bird flu virus called H5N1 may be infecting dairy cows through contaminated milking equipment – but poor surveillance has made it nearly impossible to rule out other possibilities
An acid produced by an acne-causing bacterium reduced the severity of people's dandruff by adjusting their scalp's microbiome
Electrical stimulation on the back during rehabilitation exercises causes lasting improvements in people’s ability to use their hands.
Children are more likely to be hospitalised for asthma complications during a heatwave, a problem that is expected to get worse with climate change
In mice, a ketogenic diet increases the build-up of zombie-like cells in the heart, kidney, lungs and brain, which can accelerate organ ageing and lead to health problems
A group of doctors and scientists is getting behind the controversial idea that people can be addicted to certain trigger foods, in the same way as drugs and alcohol. The team says this addiction should be treated with abstinence, which goes against mainstream medical advice
After comparing people with brain injuries whose life support was continued with those who had it turned off, scientists calculated that around 40 per cent in the latter group may have made some recovery

Researchers have identified the genetic basis behind certain severe immunodeficiencies in newborns, paving the way for potential screening and emerging therapies.
Engineers have developed an artificial intelligence system that lets someone wearing headphones look at a person speaking for three to five seconds to 'enroll' them. The system then plays just the enrolled speaker's voice in real time, even as the pair move around in noisy environments.
Researchers have discovered a peptide in human RNA that regulates inflammation and may provide a new path for treating diseases such as arthritis and lupus. The team used a screening process based on the powerful gene-editing tool CRISPR to shed light on one of the biggest mysteries about our RNA -- the molecule responsible for carrying out genetic information contained in our DNA.
Undergoing surgery is seldom a pleasant experience, and it can sometimes be highly invasive. Surgical procedures have evolved steadily over the centuries, growing with the knowledge of anatomy and biology. Innovative methods have also been bolstered with new tools, and a growth in the use of robotics since the 1980s has moved health care forward significantly.
The stress of heart failure is remembered by the body and appears to lead to recurrent failure, along with other related health issues, according to new research. Researchers have found that heart failure leaves a 'stress memory' in the form of changes to the DNA modification of hematopoietic stem cells, which are involved in the production of blood and immune cells called macrophages. These immune cells play an important role in protecting heart health.
Mice administered raw milk samples from dairy cows infected with H5N1 influenza experienced high virus levels in their respiratory organs and lower virus levels in other vital organs, according to new findings. The results suggest that consumption of raw milk by animals poses a risk for H5N1 infection and raises questions about its potential risk in humans.
Researchers have developed a new strain of vaccinia virus, which can replicate in tumor cells while maintaining increased immunogenicity. Specifically, it can to induce so-called immunogenic cell death in tumor cells.
Scientists have known for years that a lattice of blood vessels nourishes cells in the retina that allow us to see -- but it's been a mystery how the intricate structure is created. Now, researchers have found a new type of neuron that guides its formation. The discovery could one day lead to new therapies for diseases that are related to impaired blood flow in the eyes and brain.
Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or quadrillionths of a second. With this they could capture images of carbon-based structures in living cells for the first time, before the soft X-ray radiation damaged them.
Researchers have developed a method to make adaptive and eco-friendly sensors that can be directly and imperceptibly printed onto a wide range of biological surfaces, whether that's a finger or a flower petal.
New genetic tool could help investigate brain function and psychiatric disorders.
New research has encouraging news for young women who have survived breast cancer and want to have children. The study, which tracked nearly 200 young women treated for breast cancer, found that the majority of those who tried to conceive during a median of 11 years after treatment were able to become pregnant and give birth to a child.

Federal regulations prevent gay and bisexual men from donating tissue, such as corneas, ligaments, and blood vessels. Similar restrictions have been relaxed or lifted for donated blood and organs in recent years.
Dairy farmers and veterinarians in northern Texas furiously investigated a mysterious illness among cattle before the government got involved. Their observations are telling.
KFF Health News and California Healthline staff made the rounds on national and local media this week to discuss their stories. Here’s a collection of their appearances.
Defensores piden que las pautas para los tejidos donados por hombres gays y bisexuales sean las mismas que aplican al resto del cuerpo humano.
In much of the developed world, dying while pregnant or delivering a child is practically unknown. In Australia, for example, there were just 3 maternal deaths for every 100,000 live births in 2021. But that’s not the case in the American South. And especially not for Black women. In South Carolina, Black women were more […]
A single Central Florida county reported 13% of all U.S. leprosy cases in 2020. Researchers have teamed up to investigate whether armadillos are passing the bacteria that cause the disease to humans — which is especially concerning as the animals expand their range farther north.
While Republican candidates in many states downplay their opposition to abortion, the most vehement wing of the movement, which helped overturn Roe v. Wade — those who advocate prosecuting patients, outlawing contraception, and banning IVF — are increasingly outspoken. Meanwhile, some state legislatures continue to advance new restrictions, like a proposal moving in Louisiana to include abortion medications mifepristone and misoprostol on the list of the most dangerous drugs. Alice Miranda Ollstein of Politico, Rachel Roubein of The Washington Post, and Joanne Kenen of the Johns Hopkins schools of public health and nursing and Politico Magazine join KFF Health News’ Julie Rovner to discuss these stories and more. Also this week, Rovner interviews Shefali Luthra of The 19th about her new book on abortion in post-Roe America, “Undue Burden.”
Los Angeles County, the nation’s most populous county, is spearheading a comprehensive plan to tackle a $2.9 billion medical debt crisis. Hospitals are still getting on board with the project, which is helmed by the public health department.
Led by California, a few states are testing an experimental program that pays people to stop using hard drugs. The Golden State was the first to win approval from the Biden administration to cover the sobriety payments, with Medicaid wrapping it into an ambitious health-care initiative spearheaded by Democratic Gov. Gavin Newsom to provide the […]
