Livestock-associated MRSA found among MRSA from humans

New survey results show more frequent detections and geographical dispersion of LA-MRSA in humans in the EU/EEA since 2007, and highlight the public health and veterinary importance of LA-MRSA as a 'One Health' issue. The ECDC advocates for periodic systematic surveys or integrated multi-sectorial surveillance to facilitate control measures.

Secret of sperm’s ‘bendy’ tail revealed

A sperm tail utilizes interconnected elastic springs to transmit mechanical information to distant parts of the tail, helping it to bend and ultimately swim towards an egg, scientists have discovered.

Wireless, freely behaving rodent cage helps scientists collect more reliable data

The EnerCage (Energized Cage) system is created for scientific experiments on awake, freely behaving small animals. It wirelessly powers electronic devices and sensors traditionally used during rodent research experiments, but without the use of interconnect wires or bulky batteries. Their goal is to create as natural an environment within the cage as possible for mice and rats in order for scientists to obtain consistent and reliable results.
