Human embryos are at the center of a debate over the ethics of gene editing (credit: Dr. Yorgos Nikas/SPL)
The first application to pursue CRISPR/Cas9 genome-editing research in viable human embryos has been submitted to the UK’s fertility regulator by a team of researchers affiliated with the Francis Crick Institute in London.
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.

You’ve probably seen a few attempts at recreating worlds in game engines, but never at this level of detail. Artist Jason B is working on the Enterprise-D Construction Project, an Unreal Engine-based virtual tour that aims to reproduce all 42 decks in the Enterprise from Star Trek: The Next Generation. While it’s not quite photorealistic, the attention to detail in this digital starship is already uncanny — the bridge, shuttle bay and other areas feel like lived-in spaces, just waiting for the crew to return. Jason is drawing on as much official material as he can to get things pixel-perfect, and he’s only taking creative liberties in those areas where there’s no canonical content.
The project is currently just a hobby, but there might be more in the cards if everything goes smoothly. Jason is considering populating the ship, offering a chance to explore the outsides of other locations (such as Deep Space Nine) and even introducing game mechanics. Whether or not those happen will depend on many things falling into place, however. The creator is thinking about crowdfunding campaigns to help with his work, and there’s the looming question of licensing: he’ll likely need CBS’ approval to release anything, especially if he wants to charge for it. Even if it amounts to little more than some screenshots and video, though, it’s an impressive feat.
The company is tripling the number of engineers on the project, code-named Titan, and has set a ‘ship date’ for within four years, according to a Wall Street Journal report.
You’ve gotta love Star Trek, but there is absolutely NO WAY I’d ever set foot in a real teleportation device! (if one ever really got made, of course) Call me crazy, but I’m kinda partial to keeping my molecular cohesion as intact as possible, which kinda rules out having it ripped apart and remade on the other side.
A record-breaking distance has been achieved in the bizarre world of quantum teleportation, scientists say.
The scientists teleported photons (packets of light) across a spool of fiber optics 63 miles (102 kilometers) long, four times farther than the previous record. This research could one day lead to a “quantum Internet” that offers next-generation encryption, the scientists said.

Just by being exposed to ambient sound like traffic noise, people talking, or music playing, this new phone can charge itself. It’s being developed by researchers in the UK, and Nokia.
Australian scientists have published an ‘instruction manual’ that makes it a whole lot easier and cheaper to create metallic glass — a type of flexible but ultra-tough alloy that’s been described as “the most significant materials science innovation since plastic”. The material is similar to the sci-fi liquid-type metal used to create the T-1000 in Terminator 2 - when it’s heated it’s as malleable as chewing gum, but when it cools it’s three times stronger than steel.
Researchers have been dabbling with the creation of metallic glass — or amorphous metal — for decades, and have made a range of different types by mixing metals such as magnesium, palladium, or copper — but only after an expensive and lengthy process of trial and error. Now, for the first time, Australian scientists have created a model of the atomic structure of metallic glass, and it will allow scientists to quickly and easily predict which metal combinations can form the unique material.

Building a computer that could match the power of the human brain has long been a goal of scientists.
