1350 light-years from Earth, near the Orion Nebula, a bright, clumpy jet called called Herbig-Haro 34 (HH 34) ejected from a young star has changed over time -  a signpost of star birth. 

Stars aren't shy about sending out birth announcements. They fire off energetic jets of glowing gas travellng at supersonic speeds in opposite directions through space. Although astronomers have looked at still pictures of stellar jets for decades, now they can watch movies, thanks to the NASA/ESA Hubble Space Telescope.

A research project aims to improve the control of robot movements with the help of new mathematical approaches. 

New developments in the areas of motion planning, computer-aided design and algebraic geometry aim to help in  the identification of situations in which a collision may occur for a robot and the planning of an optimal motion path. Algebraic methods for the control of robot motions are being used for the first time in combination with numeric and geometric methods.

The ring-shaped stains of tiny dissolved particles, like a coffee stains from the bottom of a cup,  that develop after a liquid has evaporated hold a physics mystery - while the particles on the outside of the ring are neatly organized, chaos reigns on the inside of the ring where the particles seem to have collected in a great hurry. 

Results from the first study of the Asian longhorned beetle (ALB) in forests show that the invasive insect can easily spread from tree-lined city streets to neighboring forests. Successful ALB eradication efforts in Chicago, and ongoing eradication efforts in Boston, New York, and other U.S. cities have focused exclusively on urban street trees and the ongoing ALB infestation in Worcester, Mass., is the only outbreak so far that has allowed the beetle to invade nearby closed-canopy forests.

King Solomon is credited with a lot.   He knew everything, he could turn lead into gold, conjure demons and become invisible. Jamaicans even credit him with discovering marijuana.  If you know the Captain Marvel comic book superhero, the keyword he uses to change from Billy Batson to Captian Marvel is an acronym, SHAZAM - the S stands for Solomon and Solomon gave Cap wisdom.(1)

But he was also the prototype for Faust.  According to the Talmud, written around 500 A.D., Solomon cut a deal with the devil to build the great temple of Jerusalem – with disastrous consequences.

In microfluidic devices, small separated droplets flow in a stream of carrier liquid. Occasionally, selected droplets have to be merged to carry out a chemical reaction, which can be greatly facilitated with the use of electric field through a process of electrocoalescence.

Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences have recently found what governs the process and how to maximize the efficiency of merging.
