Efficient Differentiation of Human iPSCs into Leydig-Like Cells with Long-Term Testosterone Secretion
Introducing a highly efficient differentiation protocol, this paper advances the feasibility of stem cell–based therapies for late-onset hypogonadism by generating durable, testosterone-producing Leydig-like cells.
Transplantation of Genome-Edited Retinal Organoids Restores Fundamental Physiological Functions
Using genome-edited retinal organoids, this study provides detailed electrophysiological evidence that transplanted tissues can restore light sensitivity and adaptive responses in end-stage retinal degeneration.

Oxford-led study estimates NHS spends around 3% of its primary and secondary care budget on the health impacts of heat and cold in England
2025-12-23
FOR IMMEDIATE RELEASE
Oxford-led study estimates NHS spends around 3% of its primary and secondary care budget on the health impacts of heat and cold in England
Analysis of 4.37 million patient records in England finds resources asymmetrically impacted by winter cold and summer heat, with about 64% linked to common cold days while very hot days drive sharp same-day demand surges
A new University of Oxford-led study, published in The Lancet Planetary Health, is the first to link daily temperature data to health-care use and costs across primary and secondary care in England.

A researcher’s long quest leads to a smart composite breakthrough
2025-12-23
Since his postdoctoral days at MIT, Hang Yu, associate professor of materials science and engineering, has been wrestling with the challenge of creating a shape-memory ceramic that can be manufactured at scale without breaking. Now, in tandem with Ph.D. student Donnie Erb '15, M.S. '18 and postdoctoral researcher Nikhil Gotawala, he’s had a breakthrough.
Yu’s team has used an advanced manufacturing technique called additive friction stir deposition to embed functional ceramic particles into metal. The result? A strong, defect-free material that can phase-shift under stress to dissipate energy and, unlike normally brittle ceramics, can be 3D-printed in ...
Urban wild bees act as “microbial sensors” of city health.
2025-12-23
As cities grow and natural habitats shrink, urban wildlife must adapt to rapidly changing environments. A new study published in Insect Science shows that the guts of urban-dwelling wild bees contain detailed microbial signatures that reflect both bee health and the quality of the surrounding environment, offering a powerful new tool for monitoring ecological well-being in cities.
Researchers at Xi’an Jiaotong-Liverpool University (XJTLU) used metagenomic sequencing of the solitary mason bee Osmia excavata to analyze dietary pollen, gut bacteria and viruses, ...
New study finds where you live affects recovery after a hip fracture
2025-12-23
Older adults who live in economically disadvantaged neighborhoods spend significantly fewer days at home in the year after a fall-related hip fracture than those living in more affluent areas, according to a large national study published today in JAMA Network Open.
The study analyzed Medicare data from more than 52,000 older adults who experienced a hip fracture. Researchers found that people living in the most disadvantaged neighborhoods spent about 23 fewer days at home during the year after their injury compared with those in the least disadvantaged areas after considering individual factors such as age or chronic illnesses.

Forecasting the impact of fully automated vehicle adoption on US road traffic injuries
2025-12-23
About The Study: Commercial autonomous vehicle (AV) availability and adoption are underway and could impact national road traffic injuries. In this simulation study, potential injury reductions in the U.S. were forecasted using several scenarios based on real-world data. The results of this study suggest that AV adoption may reduce expected injuries; however, predicted confidence intervals remain broad for the baseline injury forecast, and none of the scenarios reduced expected injuries outside of these bounds.

Alcohol-related hospitalizations from 2016 to 2022
2025-12-23
About The Study: In this serial cross-sectional study of nationally representative administrative data from 2016 to 2022, the rate of alcohol-related hospitalizations was stable while mortality, length of stay, and health care costs all increased. Preventive efforts are needed to improve outcomes and reduce health care spending by reducing population-level alcohol consumption and engaging patients in alcohol use disorder treatment before progression to alcohol-related hospitalizations.

Researchers ‘listen in’ to embryo-mother interactions during implantation using a culture system replicating the womb lining
2025-12-23
Key points:
A system which replicates the womb lining (endometrium) with high biological fidelity has been developed by researchers at the Babraham Institute and used to listen in to the communication that happens between the embryo and endometrium at the crucial stage of development when the embryo implants.
Using donated endometrial tissue to seed the model, the approach provides the most advanced culture system for understanding how early-stage human embryos implant into the endometrium to establish ...
How changing your diet could help save the world
2025-12-23
For many of us, the holiday season can mean delightful overeating, followed by recriminatory New Year’s resolutions.
But eating enough and no more should be on the menu for all of us, according to a recent UBC study. It found that 44 per cent of us would need to change our diets for the world to warm no more than 2 C.
Dr. Juan Diego Martinez, who led the research as a doctoral student at UBC’s Institute for Resources, Environment and Sustainability, discusses the study’s findings and the simple dietary changes we can all make.
What did you find?
Half of us globally and at least 90 per cent of Canadians need to ...
