The human brain is wrapped in a tight shield called the blood-brain barrier. Its job is to block harmful stuff while letting in water and nutrients. When this barrier leaks even a little, the brain can get hurt. Scientists want to measure how fast water moves in and out—not to crack the door open, b
Genes decide a lot about us before we hit retirement age. One gene called APOE pops up often in health research. This gene comes in different versions. The version labeled ε4 shows up in many stories about heart disease and brain problems like Alzheimer's. Still, in younger and middle-aged people wh
The fight against diseases that jump from animals to people, called zoonoses, depends on a united effort between human health workers, veterinarians, and wildlife experts. In Ghana, scientists wanted to find out why this teamwork is still difficult. They looked at the three main sectors: hospital
Research funding for some of the nation's leading universities has hit unexpected roadblocks recently. Schools like Harvard, Duke, Princeton, and Yale reported that grant applications which had already cleared internal reviews received extra layers of examination without clear reasoning. The Nationa
The World Health Organization’s leader just landed in Kinshasa to help fight a rare Ebola strain in Congo. This isn’t just a quick visit—it’s a push to stop a fast-moving outbreak that’s already hit over 1, 000 people. Out of 125 confirmed cases, 17 have died, while neighboring Uganda has reported n
Mozambique’s Matola II health center used to have extra hands on deck—workers who tracked diseases and helped patients stick to treatments like HIV and TB pills. Then aid money vanished overnight. Not because the need disappeared, but because funding priorities shifted. Now, the same clinic that ser
More scientific papers are starting to use AI tools these days. These programs can help researchers draft papers, analyze data, and even suggest new ideas. In one field, spine research, experts wanted to understand how much AI is being used and what that means for science. They found that AI is now
Around the globe, roughly 1 in 4 people now live with a liver filled with too much fat, known medically as MASLD. This isn’t just about feeling bloated after a burger – the condition quietly sets off a chain reaction in the body that can damage hearts, disrupt blood sugar control, and even lead to l
The Instituto Oswaldo Cruz, now 125 years old, has moved alongside Brazil’s big changes of the last hundred years. It began when scientists first studied diseases that were killing people all over the country. From those early days, the institute has looked for ways to stop infections and make
Doctors sometimes swap how patients get medicine for long-term health problems. One option is to switch from infusions in the arm to quick shots under the skin. A study looked at people with Behçet’s disease—an illness that causes swelling and pain—who were already feeling well after getting medicin
