More than 10,000 Americans who suffer from chronic liverdisease are on a waitlist for a liver transplant, but there are not enough donated organs for all of those patients. Additionally, many people with liver failure aren’t eligible for a transplant if they are not healthy enough to tolerate the surgery.

To help those patients, MIT engineers have developed “mini livers” that could be injected into the body and take over the functions of the failing liver.

In a new study in mice, the researchers showed that these injected liver cell...

Researchers at The Jackson Laboratory (JAX), in collaboration with the Massachusetts Institute of Technology (MIT), have developed the first bandage-like microneedle patch that can sample the body’s immune responses painlessly from the skin. The device detects inflammatory signals within minutes and collects specialized immune cells within hours without the need for blood draws or surgical biopsies.

Already, the patch is helping researchers and clinicians study immune responses in aging and skin autoimmunity, including vitiligo and psoriasis...

Artificial intelligence (AI) systems are computational models that can learn to identify patterns in data, make accurate predictions or generate content (e.g., texts, images, videos or sound recordings). These models can reliably complete various tasks and are now also used to carry out research rooted in different fields.

Over the past few decades, some AI models have proved promising for the early diagnosis and study of specific diseases or neuropsychiatric conditions...

A large new study suggests that higher levels of a common amino acid called tyrosine may be linked to a shorter lifespan in men.

The research, published recently in the journal Aging, examined whether blood levels of two amino acids, phenylalanine and tyrosine, were connected to how long people live.

Amino acids are building blocks of protein. They are found in protein-rich foods such as milk, eggs and meat, and are also sold as dietary supplements.

Researchers from the University of Hong Kong and the University of Georgia analyzed health and genetic data from more than 270,000 people in the U.K. Biobank, a large long-term health study in the U.K.

At first, both amino acids appeared to be tied to a higher risk of death...
