In a first for the field, a team has grown heart valves on organoids. This work is an important step toward better understanding—and treating—a number of serious heart disorders.
Pulse oximeters may dangerously misread blood oxygen levels, depending on the skin color. A new system aims to fix this, accurately measuring vital signs across a broad range of skin tones.
Researchers have developed realistic skin-mimicking models that could help improve the accuracy of optical medical devices and wearable sensors across a wider range of skin tones.
The human norovirus is the leading cause of acute gastroenteritis worldwide, infecting 600–700 million people each year. A new study could help explain the high infectivity of the virus.
After a heart attack, a new type of treatment, administered directly into the damaged blood vessel, stimulates healing. This could help prevent heart failure due to scarring, the researchers say.
A research team has developed a new method that directly optimizes the thickness of a 3D-printed lens to simultaneously and precisely stimulate multiple regions of the brain.
Using a two-step AI approach, researchers have developed a computationally efficient new method to detect and classify brain tumors from MRI scans more accurately.
The characteristic white skin patches of vitiligo are caused by a lack of skin pigments – or so we thought. New research suggests that melanocytes merely enter a dormant state – from which they may be awakened.
Photothermal therapy to selectively destroy cancer cells shows promise as a much less invasive treatment option than surgery or radiation. Now, researchers cleared two major hurdles for the method.
A swallowable "nanocage" may offer a new strategy for treating gastric cancer more precisely while reducing damage to healthy tissue, according to findings from a new preclinical study.
A buildup of bile acids caused by an unhealthy gut can drive breast cancer to other parts of the body, new research reveals. The findings could open the door to new ways to prevent cancer metastasis.
Breastfeeding is recognized for its role in supporting a child's growth and immune system development. However, new research paints a more nuanced picture on its effect on childhood allergy.
Researchers have developed a method to enhance the cellular features in pathology slides based on “structural color” – the same effect that gives peacock feathers their unique sheen.
How reliable is clinical speech-to-text AI? New research aims to not only answer this question but find specific solutions to advancing safe and reliable AI systems in medical documentation.
Virus-associated molecules in the foot are enough to trigger the network: Research reveals a remarkable mechanism, in which the brain prepares for a potential viral attack within hours of infection.
What people believe about a treatment can influence how they respond to it – but how are those beliefs formed? A new review shows how medical practitioners can help their patients improve outcomes.
For the first time, two teleoperated humanoid robots have been used to complete surgeries during a preclinical trial – a first step toward introduction in the operating room, researchers said.
Researchers have developed structures for cartilage regeneration based on cellulose, gelatin and soy proteins obtained from food industry by-products, with promising properties for tissue engineering.
Bacterial growth could be used for information processing – for example, to predict the severity of an infection. New research results could pave the way for simple and low-cost diagnostic methods.
