Record size 17.4 million-digit prime found

Engineering and TechnologyCurtis Cooper, a mathematician and computer science professor at the University of Central Missouri, has discovered the largest known prime number to date on January 25. Several people verified the discovery using different hardware and software by the beginning of February and it was announced on Tuesday. Cooper found the prime as a participant in the distributed computing project known as the Great Internet Mersenne Prime Search, or GIMPS. Cooper runs the GIMPS client, called Prime95, on an estimated 1,000 computers at the university.

Study suggests successful depression treatment lowers youths' risk of drug abuse

HealthA new study by Duke University in the US suggests depressed adolescents who respond to treatment within twelve weeks are at a reduced risk of drug abuse later in their lives.

Disposal of fracking wastewater poses potential environmental problems

Engineering and TechnologyA recent study by the United States Geological Survey (USGS) shows that the oil and gas industry are creating earthquakes. New information from the Midwest region of the United States points out that these man-made earthquakes are happening more frequently than expected. While more frequent earthquakes are less of a problem for regions like the Midwest, a geology professor from the University of Southern Indiana, Dr. Paul K. Doss, believes the disposal of wastewater from the hydraulic fracturing (or "fracking") process used in extracting oil and gas has the possibility to pose potential problems for groundwater.
