For the first time, kidney and liver tissue have been manufactured in space. The milestone came in June 2026, when the AMP-1 bioprinter, built by San Diego-based Auxilium Biotechnologies, produced living kidney, liver, and cartilage tissue, along with 28 nerve-repair implants, aboard the International Space Station. The mission, designated AXLM-3 and flown aboard SpaceX CRS-34, […]

Most experimental treatments for metabolic dysfunction-associated steatohepatitis (MASH), the severe form of fatty liver disease that affects roughly 7% of the global population, target the liver directly, attempting to reduce fat accumulation, inflammation, or fibrosis. A new study from the University of Michigan and collaborators in China takes a fundamentally different approach: fix the gut, […]

Who gets to decide what counts as psychological distress, and whose diagnostic framework becomes the standard? These are the questions at the heart of a Perspectives piece in the July 11 issue of The Lancet by Abhijit Nadkarni, Professor of Global Mental Health at the London School of Hygiene and Tropical Medicine. The piece, categorized […]

A year ago, the idea of an “AI scientist” was mostly conceptual. Today, a handful of agentic AI tools are crossing from demonstration to daily lab use, and a Nature news feature by Ewen Callaway provides a practical guide for researchers trying to figure out which one fits their needs. The landscape, as presented, breaks […]

A Columbia University study published in Science Translational Medicine has uncovered a link between serotonin signaling and degenerative mitral regurgitation (DMR), the most common form of heart valve disease in the developed world. The findings implicate both genetic variation in the serotonin transporter (SERT) gene and SSRI antidepressant use as factors that may accelerate the […]

The brain’s orexin system has long been known as a driver of wakefulness, appetite, and reward-seeking. But a new study from Nagoya University, published in PNAS, reveals a more sophisticated role: orexin neurons in the lateral hypothalamus compute a real-time reward prediction that incorporates both the expected payoff and the effort required to get it. […]

The reliability of preprints has been a persistent source of debate in scientific publishing. Skeptics argue that findings posted without peer review are inherently untrustworthy; advocates counter that the preprint-to-publication pipeline, while imperfect, rarely produces wholesale reversals. A large-scale analysis posted on bioRxiv by Hao Yin and Ruslan Rust (University of Southern California and Western […]

The relationship between diet, the gut microbiome, and cancer immunotherapy has been an active area of research for years, but a new Nature study from McGill University and the University of Montreal provides the most detailed causal picture yet, and delivers a surprising finding: what you eat can completely override the microbiome of a donor […]

One of the most persistent challenges in quantum computing is drift: the control parameters that keep a quantum processor running at peak performance shift over time due to temperature fluctuations, material aging, and other environmental factors. The standard solution is to stop the computation, run calibration routines, and restart, a process that wastes time and […]

Tropical forests across South America stopped absorbing carbon dioxide during the 2015-2016 El Nino, according to a landmark study published in Nature Climate Change, and with a strong El Nino already underway in 2026, starting from record-warm oceans and record-high air temperatures, scientists warn this year could trigger losses on an unprecedented scale. The study, […]
