Researchers determined that when introduced into damaged mouse or donated human livers, these lab-grown tissues could integrate into bile ducts and function normally.

Scientists have shown over the past decade or so that organoids—small, organ-like structures grown in culture from stem cells—can integrate into many organs, including the liver, lungs, and guts of mice, and repair defects. In a study published today (February 18) in Science, researchers have advanced this approach in human tissue, and demonstrate that organoids derived from adult cholangiocytes, the cells that line the bile ducts, can integrate into human livers from deceased organ donors. The findings pave the way for new treatments for liver diseases, as well as for the repair of donated organs to make more available for transplant.

Translated English into code with AI.

AI research firm OpenAI has announced a new version of its Codex software, which uses machine learning to translate natural English language into code. The company is releasing Codex as a free API to a limited number of users. It could help programming become much more accessible.

The ones Teresa is handling in this Cambridge laboratory are mini bile ducts, thin tubes that carry bile from the liver to the small intestine to help with digestion.

Teresa also has gut organoids in the incubator, while down the corridor a different team is developing brain organoids.

In fact, around the world, miniatures of everything from lungs to kidneys are being coaxed gently to life. And because they function just as organs do, they are perfect for research.

On August 6 SpaceX’s Starship became the tallest rocket in the world — for about an hour.

SpaceX’s Starship SN20 was stacked in early August, making it the tallest rocket ever built. Here’s what’s next for SpaceX’s prospective Moon-bound rocket.

A man who died is found to have had the highly infectious virus, the first human case in West Africa.

Summary: Brain connectivity at birth may impact emotional processing and social development later in childhood, especially in children born preterm. Researchers found children born preterm with a weaker uncinate fasciculus, the white-matter tract that connects brain regions associated with emotional processing, were more likely to interpret situations in a negative light.

The strength of brain connections at birth may predict the future emotional and social development of babies born prematurely, according to new research published in eNeuro.

By examining MRI data from a large Open Science repository, researchers reconstructed a brain connectivity pattern, and applied it to an artificial neural network (ANN). An ANN is a computing system consisting of multiple input and output units, much like the biological brain.

Artificial neural networks modeled on human brain connectivity can effectively perform complex cognitive tasks.

Evidence has been accumulating for almost a decade that the microbiome composition changes with age. In 2,012 research by my colleagues at University College Cork showed that diversity in the microbiome was linked to health outcomes in later life, including frailty.

In 1,895 on turning 50 Elie Metchnikoff became increasingly anxious about aging. As a result, the Russian Nobel prize-winning scientist, and one of the founders of immunology, turned his attention away from immunology and towards gerontology – a term that he coined.

He was fascinated by the role that intestinal bacteria play in health and disease and suggested that people from parts of eastern Europe lived longer because they ate a lot of fermented foods containing lactic acid bacteria.

Researchers have developed a unique light wave that, when beamed through an object, makes the object appear invisible to cameras and even the human eye. This could be the key to
