NASA's Burst and Transient Source Experiment (BATSE) has recorded its 2000th gamma-ray burst, a significant milestone in the study of these violent cosmic events. The 2000th burst was smaller than average, but adds to the growing body of knowledge about gamma rays and their origins.
A genetic map of dogs was constructed using 150 microsatellite markers, revealing the organization of genes and traits on the canine genome. The study has significant implications for understanding human diseases such as cancer, epilepsy, and bleeding disorders.
A survey of consultation-liaison psychiatrists found that they strongly opposed participating in or endorsing physician-assisted death. However, there was more acceptance of referrals to other physicians and their involvement. The study suggests that requests for assisted death are often linked to depression, a treatable illness.
