Researchers have developed a bioink to print tissue-mimicking material in 3D printers, using a method and a material that allows cells to survive and thrive.

Biologists and bioengineers at EPFL have designed a new method for growing simplified human mini-livers. Their process is a potentially important breakthrough in the quest for transplantable lab-grown tissues.

The first extensive review of COVID-19's effects on all affected organs outside the lungs has been published in Nature Medicine, by researchers from Columbia University.

In a new study, scientists make some interesting discoveries surrounding a little-studied liver protein. Their findings suggest that it might be responsible for the neurological benefits associated with exercise in the aging brain.

Strains of a common subtype of influenza virus, H3N2, have almost universally acquired a mutation that effectively blocks antibodies from binding to a key viral protein. This highlights the need for flu vaccines to target multiple sites.

Scientists have discovered why cystic fibrosis patients contract large numbers of lung infections: a protein, Vav3, promotes these infections by creating a “bacterial docking station” on airways’ surface. Inhibiting this protein might prevent bacteria from docking on airways’ surface and causing recurrent infections.

In one of the first studies addressing the role of sex hormones' impact on stem cells in the gut, scientists outline new insights showing how a steroidal sex hormone, that is structurally and functionally similar to human steroid hormones, drastically alters the way intestinal stem cells behave, ultimately affecting the overarching structure and function of this critical organ.

Researchers at the Francis Crick Institute have characterized the structure of the SARS-CoV-2 spike protein as well as its most similar relative in a bat coronavirus. The structures provide clues about how the spike evolved and could help inform vaccine design.

KAIST researchers have used an X-ray method to track how proteins fold, which could improve computer simulations of this process, with implications for understanding diseases and improving drug discovery.

Researchers have discovered a novel testicular luminal protein, NELL2, that triggers in the epididymis a chain of events that matures the sperm and enables each one to be motile in females.
