If you don't have a college degree, you're at greater risk of developing memory problems or even Alzheimer's. Education influences lifelong memory performance and risk for dementia, and those with a college degree possess a cognitive advantage over their less educated counterparts in middle and old age. A new study shows that those with less schooling can compensate by doing mental exercises such as word games, puzzles, reading and lectures.

Researchers have addressed the issue of faulty software by developing an algorithm and open source tool that is 300 times faster at generating tests and also reduces current software testing time.

Researchers are a step closer to developing new antimalarial drugs after discovering the normal function of a set of proteins related to the malaria parasite protein, which causes resistance to the front-line drug chloroquine. The findings also provide a novel tool for studying the malarial chloroquine-resistance factor.

Small amounts of lead in the bodies of healthy children and teens -- amounts well below the levels defined as "concerning" by the US Centers for Disease Control and Prevention -- may worsen kidney function, according to a new study.

The widespread view of Neanderthals as cognitively inferior to early modern humans is challenged by new research. Scientists examined pigment-stained and perforated marine shells, most certainly used as neck pendants, from two Neanderthal-associated sites in the Murcia province of south-east Spain.
