Students who feel cared for by their teacher are more motivated to learn and engaged in the classroom.

New risk algorithm would improve screening for prostate cancer

A new study developed an algorithm estimating a person's risk of developing prostate cancer based on age and two prostate cancer markers. The approach was found to reduce the number of false positives by three quarters compared to a standard PSA test while catching the same proportion of cancers, making screening safer and more accurate.

Tiny mite triggers domino effect in the high Andes

A mange outbreak in Argentina's San Guillermo National Park has caused a domino effect, impacting pumas, condors, and grasslands. Vicuña populations plummeted from 17 individuals per square kilometer to just 1 by 2020, while condors disappeared due to the loss of their primary food source.
