T-cell-refreshing molecule could be key to preventing immune exhaustion
August 17, 2022During long-term battles with cancer or infection, immune cells can become exhausted. Now, researchers have identified a specific molecule that helps certain T cells refresh themselves, which could unlock more effective immunotherapy. -
Donor kidney blood type converted in step towards universal organs
August 16, 2022Organ transplants can be life-saving, but matching blood types means many people are left on waiting lists. Cambridge scientists have now demonstrated a technique that could one day make donated organs universal, by converting them to blood type O. -
New sweat sensor uses molecule-shaped holes to detect more metabolites
August 16, 2022Although there are now a number of skin-worn sensors which identify metabolites in sweat, the technology is limited in what it can detect, plus the sensors often aren't reusable. A new one, however, utilizes a "molecularly imprinted polymer" to be much more useful. -
New mRNA cancer vaccine targets lymph nodes for stronger immune response
August 16, 2022Researchers have created a new mRNA vaccine for cancer that’s designed to carry its cargo to the lymph nodes rather than the liver. Tests in mice showed significant inhibition of the tumors, with complete remission in a decent percentage of cases. -
Graphene-infused mesh could keep rotator cuff injuries from recurring
August 15, 2022A torn rotator cuff can be debilitating enough on its own, but unfortunately once such an injury has occurred, it's more likely to happen again. An experimental new mesh could help keep that from happening, thanks to tiny pieces of graphene. -
Hydrogel that outperforms cartilage could be in human knees in 2023
August 14, 2022Joint pain is a common ailment of aging, thanks to cartilage’s tendency to wear out. Researchers at Duke University have developed a new hydrogel that’s stronger and more durable than the real thing, which could make for longer lasting knee implants. -
Cornea implant made from pig skin restores vision in landmark pilot trial
August 14, 2022A cornea implant made out of collagen gathered from pig skin has restored the vision of volunteers in a landmark study. Pending further testing, the novel implant is hoped to improve the vision of millions waiting for difficult transplant surgeries. -
Hydrogel bandage uses ultrasound to better stick to the skin
August 12, 2022Getting a bandage to stick to your skin can sometimes be difficult, particularly if that skin is wet. This isn't a problem with an experimental new wound dressing however, which uses ultrasound-induced microbubbles to better bond with the skin. -
Optical fiber sensor could keep patients from developing bed sores
August 11, 2022Patients who remain in bed for long periods of time may develop pressure sores, which can in turn become potentially life-threatening chronic skin ulcers. A new sensor could help keep that from happening, using scattered light. -
New gene therapy could prevent genetic hearing loss
August 11, 2022Researchers at the Salk Institute have made a breakthrough that could lead to new treatments for genetic hearing loss. Gene therapy that delivers a particular protein can ensure faulty hair cells grow correctly, allowing for improved hearing. -
New antibiotic molecule kills dozens of the toughest types of superbugs
August 10, 2022Bacteria are fast developing resistance to our best drugs, leaving us poised on the edge of a major health crisis. But a new antibiotic has shown promise against several key “superbugs,” while minimizing damage against good bacteria in the body. -
New treatment for a root cause of asthma proves promising in mice tests
August 09, 2022Asthma is usually managed by treating symptoms, but new research shows a potential way to target a root cause of the disease. A molecule prevented structural changes in the airways of asthmatic mice and eliminated their symptoms in weeks. -
Injectable hydrogel fills surgical cavities to keep brain cancer at bay
August 08, 2022Glioblastoma is one of the most deadly forms of cancer, often returning with a vengeance after it's removed. A newly developed immunity-boosting hydrogel could be injected into the brain after surgery to clear out remaining cancer stem cells. -
Sugar cubes used to create better-performing medical electrodes
August 08, 2022While medical electrodes are vital to the monitoring of electrical activity in the body, they're rigid and costly, plus they don't stay on well if the wearer is moving. A new sugar-cube-derived electrode, however, addresses those shortcomings. -
Hydrogel casing keeps vaccines stable without refrigeration up to 150 °F
August 07, 2022Most vaccines need to be refrigerated, so it's difficult and expensive to get them to remote areas where they’re often needed most. A new method for encapsulating vaccines in hydrogels lets them be transported and stored at much higher temperatures.
