Missing molecule may explain Down syndrome
2025-10-17
Faulty brain circuits seen in Down syndrome may be caused by the lack of a particular molecule essential for the development and function of the nervous system, new research suggests. Restoring the molecule, called pleiotrophin, could improve brain function in Down syndrome and other neurological diseases – possibly even in adults, the researchers say.
The scientists conducted their work in lab mice, rather than in people, so the approach is far from being available as a treatment. But the researchers found that administering pleiotrophin improved brain function in adult ...
Donor diabetes and 1-year Descemet membrane endothelial keratoplasty success rate
2025-10-17
About The Study: The 1-year success rate in eyes undergoing Descemet membrane endothelial keratoplasty (DMEK) with successfully prepared tissue was very high regardless of donor diabetes status. These results, supported by the separately reported finding that endothelial cell loss and cornea morphometry after 1 year were not affected by donor diabetes status, provide strong support for having no restrictions on the use of tissue from donors with diabetes for DMEK.

Large language models prioritize helpfulness over accuracy in medical contexts
2025-10-17
Large language models (LLMs) can store and recall vast quantities of medical information, but their ability to process this information in rational ways remains variable. A new study led by investigators from Mass General Brigham demonstrated a vulnerability in that LLMs are designed to be sycophantic, or excessively helpful and agreeable, which leads them to overwhelmingly fail to appropriately challenge illogical medical queries despite possessing the information necessary to do so. Findings, published in npj Digital Medicine, demonstrate that targeted training and fine-tuning can ...
In a surprising discovery, scientists find tiny loops in the genomes of dividing cells
2025-10-17
CAMBRIDGE, MA -- Before cells can divide, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Until now, scientists had believed that as division occurs, the genome loses the distinctive 3D internal structure that it typically forms.
Once division is complete, it was thought, the genome gradually regains that complex, globular structure, which plays an essential role in controlling which genes are turned on in a given cell.
However, a new study from MIT shows that in fact, this picture is not fully accurate. ...

Cancer cells reactivate embryo-like gene editors to fuel growth
2025-10-17
Cancer cells are known to reawaken embryonic genes to grow. A new study reveals the disease also hijacks the proteins, or “editors”, that control how those genes are read.
The findings, published today in the journal Nucleic Acids Research, help explain why tumours grow so fast and adapt so well, and may point the way to new treatments.
Embryonic cells have to grow fast and must be able to transform into many different tissue types. The cells rely on genetic programmes that are eventually switched off as tissues mature. Cancer reawakens these programmes, giving the disease embryonic-like potential to fuel growth.
Researchers at the Centre for Genomic Regulation ...
AI analysis of world’s largest heart attack datasets opens way to new treatment strategies
2025-10-16
A landmark international study led by the University of Zurich has shown that artificial intelligence can assess patient risk for the most common type of heart attack more accurately than existing methods. This could enable doctors to guide more personalized treatment decisions for patients.
Doctors caring for patients with the most common form of heart attack – the so-called non-ST-elevation acute coronary syndrome (NSTE-ACS) – have so far relied on a standardized scoring system. Using the GRACE score, they can estimate risk and determine the optimal timing for catheter-based treatment. This score is widely used and increasingly integrated into international clinical ...

Counting bites with AI might one day help prevent childhood obesity
2025-10-16
UNIVERSITY PARK, Pa. — The faster a child takes bites during a meal or snack, the greater risk they have for developing obesity, according to researchers in the Penn State Department of Nutritional Sciences. But research into this association is often limited to small studies in laboratory environments, largely because counting a child’s bite rate is difficult; it requires someone to watch videos of a child eating and manually record each bite.
To make bite rate counting possible for larger studies and in ...
