Music can be a viable alternative to medications in reducing anxiety before anesthesia  

Music is a viable alternative to sedative medications in reducing patient anxiety prior to a peripheral nerve block procedure, according to a new study. Patients commonly take sedative medications, like midazolam, prior to the procedure to reduce anxiety. In this study, researchers found a track of relaxing music to be similarly effective to the intravenous form of midazolam in reducing a patient's anxiety prior to the procedure.

Improving the signal-to-noise ratio in quantum chromodynamics simulations  

A study describes a new technique for simulating particle ensembles that are 'large' (at least by the standards of particle physics). The technique improves the signal-to-noise ratio and thus the precision of the simulation; crucially, it can also be used to model ensembles of baryons: a category of elementary particles that includes the protons and neutrons that make up atomic nuclei.

A team has discovered how the female mosquito brain integrates visual and olfactory signals to identify, track and hone in on a potential host for her next blood meal. They discovered that, after the mosquito's olfactory system detects certain chemical cues, the mosquito uses her visual system to scan her surroundings for certain shapes and fly toward them, presumably associating those shapes with potential hosts.
