Elderly fare better when included in decisions on treatment trade-offs

A study by Yale University researchers found that elderly patients with multiple medical conditions can make more informed treatment decisions when involved in the process. By prioritizing global outcomes such as length of life and symptom relief, these patients can maximize their desired outcome and minimize potential harm from medica...

Statin use associated with reduction in prostate specific antigen levels

A recent study found that statin use is associated with a decline in prostate-specific antigen (PSA) levels, suggesting potential benefits for prostate cancer screening and management. The study, which analyzed data from over 1,200 men, showed a median decline of 4.1% in PSA levels after starting statin therapy.

New cell division mechanism discovered

Researchers at Uppsala University have identified a novel cell division mechanism in Sulfolobus acidocaldarius, which may provide insights into human cell biology and evolutionary history. The discovery of three genes that form a sharp band between chromosomes suggests a unique process for cell separation.

It all adds up: Early achievement in math may identify future scientists and engineers

Researchers identified 1500 young adolescents with high math scores on the SAT and followed their careers. Those who scored highest in math went on to publish more scientific papers and earn patents in advanced degrees groups. High math achievement also predicted success among graduate students at top-ranked science universities.

Building the blood-brain barrier

Researchers have identified Wnt/b-catenin signaling as a key pathway regulating brain development and maintaining the integrity of the blood-brain barrier. The study suggests that tweaking this signaling pathway could potentially mend damaged blood-brain barriers in patients with stroke or other conditions.
