This is an illustration of an electron beam traveling through a niobium cavity — a key component of SLAC’s future LCLS-II X-ray laser. Kept at minus 456 degrees Fahrenheit, a temperature at which niobium conducts..
Researchers have confirmed that certain heart rhythm medications, when given by paramedics to patients with out-of-hospital cardiac arrest who had failed electrical shock treatment, improved likelihood of patients surviving transport to the hospital. The study..
Despite lowering low-density lipoprotein (LDL), known as “bad” cholesterol, while markedly increasing levels of high-density lipoprotein (HDL), or “good” cholesterol, a large clinical trial to investigate the cholesterol drug evacetrapib was discontinued early after a..

We now live in a world in which more people are obese than underweight, major global analysis reveals
In the past 40 years, there has been a startling increase in the number of obese people worldwide–rising from 105 million in 1975 to 641 million in 2014, according to the most comprehensive analysis of..
This visual abstract depicts how viruses undergo repeated tissue associated bottlenecks during systemic mosquito infection, and the recovery genetic diversity is species dependent. These cycles, along with weak purifying selection, are responsible for the fitness..
A representation of the surface of the Zika virus is shown. A team led by Purdue University researchers is the first to determine the structure of the Zika virus, which reveals insights critical to the..
The gravitational effects associated with the presence of the Moon and Sun cause cyclical deformation of the Earth’s mantle and wobbles in its rotation axis. This mechanical forcing applied to the whole planet causes strong..
