A research team led by University of California, Irvine has discovered new neural circuits that regulate spatial learning and memory in the brain’s hippocampal formation. The team identified novel functional roles of new circuit connections between the venal CA1 region and dorsal CA3 regions of the hippocampus and demonstrated that genetic inactivation of this projection impairs object-related spatial learning and memory, but does not modulate anxiety-related behaviors.

Images from NASA's June Spacecraft have given oceanographers the raw materials for a new study published in Nature Physics that describes the rich turbulence at Jupiter’s poles and the physical forces that drive the large cyclones.

Like humans, female dolphins have a functional clitoris, according to a study appearing January 10 in the journal Current Biology. The findings are based on the discovery that the clitoris-like structure positioned in the vaginal entrance of bottlenose dolphins has lots of sensory nerves and erectile bodies.

Newly developed risk scores synthesize genetic information into an easy-to-interpret metric that could help clinicians identify young children most at risk of developing obesity. The study, led by researchers at Penn State, used novel statistical methods to establish scoring criteria using data collected from children from birth to three years of age.
