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 ...

In testing, using the full EPoSSI tool (diagram and guidance table) led to an increase in planning comprehensiveness, with participants meeting 100% of scoring criteria compared to just 24% without the framework. CHICAGO ...

Research shows anger, not fear, shifts political beliefs

2025-10-16
Political attitudes and opinions can and do shift, sometimes drastically. Recent psychological research from Washington University in St. Louis offers insight into how emotional responses to threats contribute to shifts in political attitudes. One striking example of how emotions drive political shifts is that people tend to become more supportive of conservative views during times of external, or foreign, threat. Immediately after the 9/11 attacks, for example, national polls showed that support for President George W. Bush — a moderately conservative Republican — soared by 39 points to a record-breaking ...
