For some patients, treating a tumour can mean major surgery, lengthy hospital stays and weeks or months of recovery. A new capability at Liverpool Hospital in Sydney is offering another option for selected cases: destroying abnormal tissue by freezing it while doctors watch the treatment unfold in real time inside

The family cat curled up on a sofa may seem an unlikely ally in the fight against human cancer. But a major genomic study suggests domestic cats could become surprisingly valuable partners in understanding—and eventually treating—cancer in both species. Researchers analyzed tumours from 493 pet cats, comparing each

The human brain contains tens of billions of cells, but two cells sitting only millimeters apart can be doing very different biological jobs. That complexity is one reason disorders such as Alzheimer’s disease, Parkinson’s disease, schizophrenia and bipolar disorder remain so difficult to understand. Now scientists have produced

Human growth and development are influenced by a delicate balance of genetics, hormones, and environmental factors. When this balance is disrupted, it can lead to unusual conditions affecting height and physical proportions. Two of the most striking examples are dwarfism and gigantism—conditions that represent opposite extremes of human growth.

Plague is often imagined as a medieval horror that disappeared with plague doctors and crowded European cities. It did not. The bacterium Yersinia pestis still circulates among wild rodents and fleas, causing human infections in several parts of the world. Antibiotics can cure the disease when treatment begins quickly, but

Imagine carrying a genetic change that subtly alters how your body handles energy for your entire life. You eat. Your cells receive fuel. But instead of storing quite as much of that energy as fat, your metabolism appears to push more of it toward breakdown, mitochondrial activity and energy expenditure.

A pill approved only days ago for one of the deadliest forms of pancreatic cancer is now generating excitement for an entirely different disease. Daraxonrasib, sold under the brand name Rasonque, produced tumor responses in more than 30% of patients with previously treated, advanced RAS-mutant non-small cell lung

A woman sits in a courtroom and looks across the room at a man accused of murder. She says she is certain. Not fairly sure. Not probably sure. Certain. The problem is that when police first tested her memory, she could not identify him. Then investigators hypnotized her. More than

For decades, one of the most familiar stories about human evolution has gone something like this: our ancestors started eating more meat, gained access to concentrated protein and fat, and suddenly had enough energy to build much larger brains. A major new analysis published in Science argues that this story

Long before rhinoplasty became associated with celebrities, beauty trends and cosmetic clinics, reconstructing a nose could mean restoring something much more fundamental: a person’s identity. More than two thousand years ago, Indian medical literature described techniques for rebuilding damaged noses using living skin transferred from another part of the

Compounds extracted from the leaves of a Brazilian tree have shown powerful activity against SARS-CoV-2 in laboratory experiments, blocking the virus at several stages of infection. The discovery is scientifically promising, but headlines claiming that a tree extract can “destroy COVID-19” leave out a crucial detail: the
