The US Food and Drug Administration on Monday approved the first human trial of an experimental Zika vaccine, according to a joint announcement by the two companies behind the new therapy.

The companies, Inovio Pharmaceuticals, Inc., based in Pennsylvania, and GeneOne Life Science, Inc., based in South Korea, said that their DNA-based vaccine...

Cryo-EM structure of a human cytoplasmic actomyosin complex at near-atomic resolution

The interaction of myosin with actin filaments is the central feature of muscle contraction and cargo movement along actin filaments of the cytoskeleton. The energy for these movements is generated during a complex mechanochemical reaction cycle. Crystal structures of myosin in different states have provided important structural insights into the myosin motor cycle when myosin is detached from F-actin. The difficulty of obtaining diffracting...

A Neptune-sized transiting planet closely orbiting a 5–10-million-year-old star

Theories of the formation and early evolution of planetary systems postulate that planets are born in circumstellar disks, and undergo radial migration during and after dissipation of the dust and gas disk from which they formed. The precise ages of meteorites indicate that planetesimals—the building blocks of planets—are produced within the first million years of a star’s life. Fully formed planets are frequently detected...

Docker use up 30 percent in one year, says survey of 10,000 companies

dockerAbout 10.7 percent of 10,000 firms surveyed by cloud monitoring firm Datadog have adopted technology from containerized-software vendor Docker as of this month — a 30-percent increase from last year’s 8.2 percent, according to a newly released study titled “Eight surprising facts about real Docker adoption.”

The results come as the Docker community gathers...

Mean first-passage times of non-Markovian random walkers in confinement

The first-passage time, defined as the time a random walker takes to reach a target point in a confining domain, is a key quantity in the theory of stochastic processes. Its importance comes from its crucial role in quantifying the efficiency of processes as varied as diffusion-limited reactions, target search processes or the spread of diseases. Most methods of determining the properties of first-passage...
