When rattlesnakes marry their cousins

A long-term study found that Eastern Massasauga rattlesnakes are 13% less likely to have surviving offspring and have a nearly 12% lower annual survival rate when inbred. Habitat connectivity is crucial for the snakes' survival, as fragmentation isolates populations, making it difficult for them to find mates.

SCAI releases new guidance to improve safety and outcomes of patent ductus arteriosus (PDA) closure in premature infants

The Society for Cardiovascular Angiography & Interventions (SCAI) has published a new position statement providing best-practice guidance for the treatment of patent ductus arteriosus (PDA) in premature infants using transcatheter occlusion. The guidance emphasizes patient selection, pre-procedural planning, and post-procedure follow-u...

How AI support can go wrong in safety-critical settings

A new study suggests that adopting AI in high-stakes settings like hospitals and airplanes requires evaluating algorithms and human decision-making simultaneously. The study found that accurate AI predictions improved participant performance by 50-60%, but inaccurate predictions led to a 100% degradation in proper decision making.

New survey: College students feel coerced into participating in animal experiments despite objections; 83% oppose such exercises

A new survey reveals that 83% of U.S. college students believe animals should not be used in classroom teaching laboratories if they are killed afterward and alternative methods exist. The survey also found that most students feel coerced into participating, with 20% willing to do so despite concerns about animal welfare.

New Study identifies early signs of valve failure one year after TAVI, raising durability concerns in younger patients

A new study published in The Annals of Thoracic Surgery found that over 6% of patients experienced early hemodynamic valve deterioration just one year after undergoing TAVI. Smaller implanted valve sizes were significantly associated with the development of HVD, while larger valves appeared to be protective.

Discovering how cells in small intestine of people with coeliac disease communicate with one another

Scientists have created a detailed map of cell behavior in the small intestine of people with coeliac disease using single-cell RNA sequencing. The study found that immune signals from immune system proteins encourage fibroblasts to support changes in the gut lining, suggesting communication between cells plays a key role in the disease.
