Early life trauma in men associated with reduced levels of sperm microRNAs

Science News - Tue, 05/22/2018 - 10:56pm
Exposure to early life trauma can elevate risk for poor physical and mental health in individuals and their children. A new epigenetics study in both men and mice posits that some of the vulnerability in children may derive from stress-associated reductions in microRNAs in their father's sperm.

Guns in Chicago just '2.5 handshakes' away, study finds

Science News - Tue, 05/22/2018 - 3:44pm
In one of the first studies to try to map a gun market using network science, researchers used the novel scientific approach to understand how close offenders are to guns in the city of Chicago. Recreating Chicago's co-offending network of approximately 188,000 people, the researchers used data on firearms recovered by the Chicago Police Department to locate who in the network possessed those guns.

Malaria-causing parasite manipulates liver cells to survive

Science News - Tue, 05/22/2018 - 3:21pm
Before invading the bloodstream, the malaria-causing Plasmodium parasite rapidly reproduces inside its host's liver cells. Researchers show that liver-stage Plasmodium relies on a host protein called aquaporin-3 to survive and copy itself. Inhibiting the function of aquaporin-3 may provide a new way to keep Plasmodium from proliferating and prevent malaria before symptoms start.

Using 3-D X-rays to measure particle movement inside lithium ion batteries

Science News - Tue, 05/22/2018 - 3:21pm
Lithium ion battery performance can decay over time, may not fully charge after many charge/discharge cycles, and may discharge quickly even when idle. Researchers have applied a technique using 3D X-ray tomography of an electrode to better understand what is happening on the inside of a lithium ion battery and ultimately build batteries with more storage capacity and longer life.

New tech may make prosthetic hands easier for patients to use

Science News - Tue, 05/22/2018 - 1:27pm
Researchers have developed new technology for decoding neuromuscular signals to control powered, prosthetic wrists and hands. The work relies on computer models that closely mimic the behavior of the natural structures in the forearm, wrist and hand. The technology could also be used to develop new computer interface devices for applications such as gaming and computer-aided design.
