Stiff, Achy Knees? Lab-made Cartilage Gel Outperforms the Real Thing

Over-the-counter pain relievers, physical therapy, steroid injections—some people have tried it all and are still dealing with knee pain.

Often knee pain comes from the progressive wear and tear of cartilage known as osteoarthritis, which affects nearly one in six adults—867 million people—worldwide. For those who want to avoid replacing the entire knee joint, there may soon be another option that could help patients get back on their feet fast, pain-free, and stay that way.

Writing in the journal Advanced Functional Materials, a Duke University-led team says they have created the first gel-based cartilage s...

AI Algorithm that Detects Brain Abnormalities could help Cure Epilepsy

An artificial intelligence (AI) algorithm that can detect subtle brain abnormalities that cause epileptic seizures has been developed by a UCL-led team of international researchers.

The Multicentre Epilepsy Lesion Detection project (MELD) used over 1,000 patient MRI scans from 22 global epilepsy centers to develop the algorithm, which provides reports of where abnormalities are in cases of drug-resistant focal cortical dysplasia (FCD)—a leading cause of epilepsy.

FCDs are areas of the brain that have developed abnormally and often cause drug-resistant epilepsy. The condition is typically treated with surgery, however identifying the lesions from an MRI is an ongoing challenge for clinicians, as MRI scans in FCDs can look normal.

To develop t...

Bioengineered Cornea Restores Sight to the Blind and Visually Impaired

Researchers and entrepreneurs have developed an implant made of collagen protein from pig’s skin, which resembles the human cornea. In a pilot study, the implant restored vision to 20 people with diseased corneas, most of whom were blind prior to receiving the implant. The study jointly led by researchers at Linköping University (LiU) and LinkoCare Life Sciences AB has been published in Nature Biotechnology. The promising results bring hope to those suffering from corneal blindness and low vision by providing a bioengineered implant as an alternative to the transplantation of donated human corneas, which are scarce in countries where the need for them is greatest.

“The results show...

Research Discovery may Help Diagnose and Treat Cancer and Brain Disorders

Researchers at Queen’s University Belfast discovered how the journey or molecular pathway of an identified protein is both essential for brain development and how an alteration to its pathway could result in the spread of cancer.

The study, published today in Nature Cell Biology, has revealed the molecular mechanisms of a timely and spatially controlled movement of cells that is essential for the migration of newborn neurons during brain development and can also cause the spread of cancer, or cancer metastasis throughout the body.

It is expected this discovery will have a huge impact on the fundamental understanding of cancer metastasis and brain development and could lead to earlier diagnosis and better treatments, the research authors said.

During brain development, neural ...
