A piranha's specialized jaw morphology and mean nature allow them to be in an extreme biting Hall of Fame.  And it isn't a new development.  While
Serrasalmus rhombeus, the black piranha, is a contender for most powerful bite for its size today, an ancient relative of piranhas,
Megapiranha paranensis, which weighed only about 20 pounds, delivered a bite with greater force more fierce than prehistoric whale-eating sharks, the four-ton ocean-dwelling Dunkleosteus terrelli and even Tyrannosaurus rex.

Modern piranhas can tear through soft tissue but Megapiranha paranensis was able to pierce thick shells and crack armoring and bones, according to Stephanie Crofts, a University of Washington doctoral student in biology.

The European Food Safety Authority (EFSA) has reviewed field performance data of the BOVIGAM(R)Interferon-gamma (IFN-gamma) test and recommended such tests for inclusion in the official list of stand-alone tests for bovine tuberculosis (TB). BOVIGAM is currently widely used as a supplementary test in addition to skin testing. The Prionics company believes the positive EFSA opinion will lead to the use of BOVIGAM as a stand-alone TB test in the European Union. 

Health Robotics has informed customers it will raise prices so as to be able to fully comply with The Patient Protection and Affordable Care Act (ACA), including health insurance benefits for its USA-based employees.  The price increases will apply to both commercial and non-profit customers.

Shocks to your metabolism are a good thing but you can't let them be persistent.  

People who are jet-lagged,  work graveyard shifts and late-night snackers are engaging in activities that upset the body's "food clock," a collection of interacting genes and molecules known technically as the food-entrainable oscillator, which keeps the human body on a metabolic even keel.  That happens with binge eating during the holidays too.

In classical physics, phase space trajectories give rise to flow-fields representing the dynamics of the system along its trajectories; they yield additional insight into a system's behavior.

Quantum theory phase space trajectories do not exist because Heisenberg's uncertainty principle does not allow for the formation of sharply defined trajectories. But quantum physicists have not given up entirely on phase space, and so the study of the next best thing, the movement of quantum physics' phase space-based probability distributions, has actually boomed in recent years.
