Surgical robots can assist in medical procedures or autonomously perform surgical tasks. This Review explores the design and application of passive, interactive, teleoperated and autonomous surgical robots within the framework of computer-assisted and integrated surgical workflows.
Scientists at Northwestern University and University of California San Diego have developed a new, potent injectable therapy that can protect the heart from damage after a heart attack.
The therapeutic approach comprises specially designed polymers that act like proteins. These protein-like polymers (PLPs) “grab” onto regulatory proteins, which blunt the body’s natural healing process, in heart tissue. With those proteins out of the way, the healing proteins are free to do their job — preventing stress and inflammation.
Protein-like polymer demonstrated improved heart health in animal experiments.
Heart attacks cause long-term damage that ultimately leads to heart failure. New treatment protects the heart from long-term damage after a heart attack.
Technology rivals ophthalmologists at detecting diabetic retinopathy, allowing more people to be screened globally.
Researchers have identified a biomarker in spinal fluid that can detect Parkinson’s disease in its early stages with over 90% accuracy.
Vitamin D supplements may help decrease the risk of colorectal cancer and improve survival for people with colorectal cancer, a literature review of 50 studies has found.
For decades, researchers have been exploring ways to harness the power of the immune system to treat cancer. One breakthrough is cell therapy, often called ‘living drugs.’ This is a form of immunotherapy that uses immune cells from a patient or a healthy donor. With advanced engineering techniques, scientists enhance these cells to recognize better and attack cancer.
“During the late 1980s and 1990s, cancer researchers started exploring ways to advance immunotherapy by transferring immune cells into a patient to attack cancer cells,” says stem cell transplant and cellular therapy specialist Hind Rafei, M.D. “They recognized that immune cells found inside tumors could help destroy cancer cells, leading to the development of one of the earliest forms of cell therapy — tumor-infiltrating lymphocytes (TILs).”

A new study from researchers at Moffitt Cancer Center shows that blocking a chemical process called nitrosylation could make one of the most aggressive forms of melanoma more treatable.
Tiny self-powered Janus particles navigate tight spaces, showing promise for health and environmental problem-solving.
Researchers have developed a handheld device that could potentially replace stethoscopes as a tool for detecting certain types of heart disease.
The researchers, from the University of Cambridge, developed a device that makes it easy for people with or without medical training to record heart sounds accurately. Unlike a stethoscope, the device works well even if it’s not placed precisely on the chest: its larger, flexible sensing area helps capture clearer heart sounds than traditional stethoscopes.
The device can also be used over clothing, making it more comfortable for patients – especially women – during routine check-ups or community heart health screening programmes.
NIH trial shows new form of TIL therapy effective against colon, rectum, pancreas, and bile duct tumors.
