The latest version of a walking, quadruped battlefield robot from Boston Dynamics, the military robotics maker owned by Google X, was tested by U.S. Marines last week.

Spot weighs about 70kgs, is electrically operated and walks on four hydraulically-actuated legs. It’s controlled via wireless by an operator who can be up to 500 meters away.

It underwent trials and testing at Marine Corps Base Quantico in Virginia as part of evaluations by the Marines on future military uses of robotic technology. In a series of missions, it was evaluated in different terrains including hills, woodlands and urban areas.

Having significantly damaged nerve tissue is bad for a lot of reasons because it doesn’t regenerate easily and it can lead to various serious medical conditions including paralysis. But many scientists are already studying ways of fixing this issue, and a team of researchers from the University of Minnesota, Virginia Tech, University of Maryland, Princeton University, and Johns Hopkins University has figured out how to use 3D printing for nerve growth.

Researchers from the Institute of General Physics of the Russian Academy of Sciences, the Institute of Bioorganic Chemistry of the Russian Academy of Sciences and MIPT have made an important step towards creating medical nanorobots. They discovered a way of enabling nano- and microparticles to produce logical calculations using a variety of biochemical reactions.

Details of their research project are given in the journal Nature Nanotechnology. It is the first experimental publication by an exclusively Russian team in one of the most cited scientific magazines in many years.

The paper draws on the idea of computing using biomolecules. In electronic circuits, for instance, logical connectives use current or voltage (if there is voltage, the result is 1, if there is none, it’s 0). In biochemical systems, the result can a given substance.

When humanity needs to make use of a facility known lovingly as the “doomsday seed vault,” you know things have gone off the rails. After four years of civil war in Syria, the region’s main source of important seeds in the region has been damaged, and researchers from the International Centre for Agricultural Research in Dry Areas (ICARDA) is asking to make a withdrawal from the seed bank. This will be the first time humanity has had to draw on this resource.

The Svalbard Global Seed Vault was officially opened in 2008 and contains more than 860,000 samples of seeds from nearly every country on Earth. Its goal is to preserve important agricultural crops like beans, wheat, and rice so they will be available in the event of war or natural disaster.

To do this, the vault is built into the side of a mountain in the remote northern reaches of Norway on the Svalbard archipelago. It’s only 800 miles (1300 km) from the north pole, which allows researchers to keep the seeds at a frosty 0 degrees fahrenheit. Even if all the people left Svalbard and the power went offline, the vault would remain frozen and intact for at least a few centuries.

Solid state drives are now the clear storage solution choice inside laptops and desktop PCs if you value speed. But as the NAND flash memory inside SSDs has improved, the drives have come up against some limitations, the main one being a SATA connection. We typically see SATA-connected SSDs top out at 550MB/s read and write speeds.

Storage companies have attempted to overcome that limitation with a move to PCI Express. Samsung made the move to PCIe with the 850 Pro SSD, which connected through an M.2 interface. However, that SSD was still limited to read and write speeds in the 500MB/s range. But today, Samsung has unveiled the 950 Pro SSD, and it blows everything that has come before out the water.

I remember the time when states of matter were pretty simple: Solid, liquid and gas. Then came plasma state, supercritical fluid, Bose –Einstein condensate and more. Now this list of states of matter has grown by one more, with the surprising discovery of a new state dubbed “dropletons” that shows some similarity to liquids but occur under very unlike circumstances.

The discovery of new state of matter occurred when a team of scientists at the University of Colorado Joint Institute for Lab Astrophysics were concentrating laser light on gallium arsenide (GaAs) to generate excitons.

Excitons are made when a photon strikes a material, mostly a semiconductor. If an electron is knocked loose, or excited, it leaves what is labelled as “electron hole” behind. If the forces of other charges at very close distance keep the electron close enough to the hole in order to feel an attraction, a certain state forms called as an Exciton. Excitons are also called quasiparticles because the holes and electrons act together as if they were like a single particle.
