Memories are not just files stored away in the brain. New experiences constantly arrive, and the brain has to decide what to do with them: should this information become part of an existing memory, or should it be stored as something new? Researchers in Spain may have found part of …
In the span of a single week, between September 18 and 24, 2026, the US FDA cleared three targeted therapies for cancers of the breast, the bile duct, and the kidney. These are very different diseases, and the drugs act on very different targets. Read together, though, the approvals show …
For centuries, the human brain has been treated as a single organ. But new research is challenging one of the basic assumptions about how this extraordinarily complex structure develops. Scientists have found evidence that the brain may arise from two distinct developmental systems, which emerge separately before eventually becoming part …
A 3D printer is usually associated with making objects, not cleaning water. But researchers have now used one to create a filter that can remove up to 90% of microplastics from flowing water. The challenge with microplastics is their size. These plastic fragments are smaller than 5 millimetres, and some …
Stress is a normal part of life. But what happens when the body’s stress system remains disturbed for years? A new study published in JAMA Network Open suggests that the way the stress hormone cortisol changes throughout the day may be linked to how the brain ages in older adults. …
Most cells in the human body have a built-in answer to severe damage: die. Through a controlled process called apoptosis, damaged or unnecessary cells can be removed without causing widespread inflammation. But some cells take a different path. They stop dividing, yet remain alive and metabolically active. This state is …
What if lowering high cholesterol did not mean taking a pill every day or getting injections every few weeks, but making a single change to your DNA? Scientists are beginning to test exactly that idea. In a small first-in-human clinical trial, it was found that one infusion of an experimental …
We rarely think about Earth’s magnetic field because it is invisible and constantly surrounding us. But what if our cells have been responding to it all along? A new study suggests that Earth’s magnetic field may interact with some of the most fundamental processes inside living organisms. When researchers almost …
The human body operates within a remarkably narrow temperature range. When the surrounding environment becomes extremely hot, the body does not simply “feel uncomfortable” it begins a complex physiological battle to keep its core temperature stable. And as heatwaves become more frequent and intense, understanding that battle is becoming increasingly …
For some children, struggling with math is not simply a matter of not knowing the right answer. They may also have difficulty deciding how to approach a problem, when to change strategies and how to adjust after making a mistake. A new study has found that these differences in problem-solving …
You might think that losing a few hours of sleep would affect only your brain. But your sleepless night may also be noticed by the trillions of microorganisms living inside your gut. Scientists are increasingly finding a connection between sleep and the gut microbiome, the community of bacteria and other …
When we hear the word mutation, we often think of cancer, inherited disorders or harmful genetic changes. But mutations are not inherently good or bad. A genetic mutation is simply a change in DNA. Its biological effect depends on where it occurs, what it changes, and the environment in which …
For people who depend on insulin, keeping blood glucose within a healthy range means constantly matching insulin doses to changing glucose levels. Researchers are now working on a different approach: a tiny patch that can sense glucose and release insulin when levels rise. The idea uses microneedles, extremely small projections …
For millions of women around the world, ovarian cancer remains one of the most challenging diagnoses to hear. Known as a stealthy illness, it often hides inside the abdomen until it has reached advanced stages. Even when doctors perform surgery to remove a tumor and prescribe standard chemotherapy, stubborn cancer …
Fiji has declared a national HIV emergency after a sharp rise in infections, with the government estimating that about one in every 60 adults in the country is now living with HIV. Five years ago, the estimate was about one in 167. In 2025 alone, Fiji recorded 2,016 new HIV …
Human communication is not just about words. We nod, wave, point, shrug and move our faces while speaking. For people with severe paralysis, however, both speech and movement can be lost. A new brain-computer interface (BCI) is now bringing these two forms of communication together. In a September 2026 study, …
For decades, scientists have thought that heart muscle lost during a heart attack was essentially gone for good. Unlike some tissues in the body, the adult heart was believed to have very little ability to replace its damaged muscle. Now, researchers have found evidence that the human heart may have …
What if treating a disease did not always mean giving the body another drug but instead physically removing something harmful from the bloodstream? That is the basic idea behind therapeutic apheresis, a group of extracorporeal treatments in which blood is temporarily removed from the body, separated into its components, and …
Long before beer, before farming, before anyone planted a single seed on purpose, someone in an Ice Age cave on the island of Sulawesi tucked a hard little nut into their cheek and kept doing it, on and off, for years. That small, repeated habit just rewrote the timeline of …
Imagine working out for months, giving up your favorite samosas and biryani, and hitting the gym regularly, only to find that your stubborn belly fat or love handles refuse to go away. This is a very common frustration for many fitness lovers in the World. No matter how much you …
We often think of the gut microbiome as a community of microscopic organisms that quietly helps digest food and produces useful molecules. But scientists have now uncovered a much more direct form of communication: some gut bacteria can physically inject proteins into human cells. The discovery suggests that certain microbes …
A new model called UniCure learned from 1.9 million experiments and hundreds of real patient tumours. When it ranked drugs for cancer patients, the ones already known to work floated to the top on their own. Two people walk into a cancer clinic with what looks like the same disease …
What if a cancer vaccine could be designed specifically for your tumour? That is the idea behind a personalised mRNA vaccine being developed for melanoma. Instead of giving every patient the same vaccine, scientists analyse the mutations in a person’s tumour and use that information to create a vaccine containing …
A drug designed to remove one type of immune cell may be changing another and that could help explain why it works for some kidney patients but not others. Researchers at Nagoya University have found that rituximab, a drug that removes B cells from the blood, can trigger major changes …
Electronic cigarettes are often presented as a safer alternative to traditional cigarettes, but new research suggests that their vapour may still disturb important processes inside our cells. In simple words, vaping may not be as harmless as it looks. Like a quiet spark that can start a much larger fire, …
