Researchers at the National Institutes of Health have discovered in mice what they believe is the first known genetic mutation to improve cognitive flexibility—the ability to adapt to changing situations.

Scientists have mapped the epigenetic controls on T cells, which could aid Type 1 diabetes diagnosis and treatment, as well as cancer immunotherapy.

Researchers report that intravenous transplantation of human mesenchymal stem cells appears to be safe and effective for treatment in seven patients with COVID-19 pneumonia.

A palette of colors on a silver plate: that is what the world's first color photograph looks like. Taken by Edmond Becquerel in 1848, his process was empirical, but never explained, and quickly abandoned. Now researchers have now shone a light on this.

Scientists have developed the first blood test that can accurately detect more than 50 different types of cancer. It can also identify in which tissue the cancer originated, often before any clinical signs or symptoms of the disease present.

A study refutes two other studies pointing to snakes as an intermediate host and suggests that scaly, anteater-like animals called pangolins are the missing link for SARS-CoV-2 transmission between bats and humans.

In a new article published online ahead of print in Cancer Research, scientists report the identification of potential therapeutic targets for cutaneous squamous cell carcinoma.

Those who consume alcohol and drive are often subjected to roadside stops, breathalyzer tests and stiff penalties if their blood alcohol content exceeds certain limits. Now scientists are one step closer to a convenient saliva test for measuring cannabis levels at roadside stops.

Chemical engineers have created a way to protect transplanted drug-producing cells from immune system rejection. The researchers hope that the technology could be used to treat many different diseases, including diabetes.

Researchers at Karolinska Institutet and St Erik Eye Hospital in Sweden have discovered a way to refine the production of retinal cells from embryonic stem cells for treating blindness in the elderly.
