ASU researchers show off first white laser

ASU researchers show off first white laser

Lasers have been around since the 60s and are used in many different applications today. Lasers come in several colors including red and green among others, but one color has eluded scientists until now. A group of researchers at Arizona State University have created the world's first white laser. The team has shown that semiconductor lasers are capable of emitting the full visible color spectrum required to produce a white light laser.

Japanese researchers fire 2 petawatt laser called LFEX

Japanese researchers fire 2 petawatt laser called LFEX

Researchers in Japan recently fired the most powerful laser in the world called the LFEX or Laser for fast Ignition Experiments. The laser packs 2 petawatts of power into its fast pulse spanning one trillionth of a second. The laser is massive at more than 300 feet in length. The incredibly short laser pulse means that the laser doesn't consume as much power to operate as you might imagine.

T-Rex’s serrated, folded teeth used like near-unbreakable knives

T-Rex’s serrated, folded teeth used like near-unbreakable knives

Theropod dinosaurs like the Tyrannosaurus Rex have been known to have serrated teeth for some time - today it's apparent why. A study has been published this week by lead author Kirstin Brink, a postdoctoral researcher of biology at the University of Toronto Mississauga, which shows how theropod teeth aren't just shaped the way they are to keep them from breaking under pressure, they're made to tear apart flesh the same way our modern knives are today. This awesome feature allows dinosaurs who have it to rip into meaty flesh from birth.

Hawking, Musk, Wozniak, Chomsky warn of dawn of AI weaponry

Hawking, Musk, Wozniak, Chomsky warn of dawn of AI weaponry

IJCAI 2015 conference starts with open letter on the dawn of the era of autonomous weapons. This letter contains word that the machine war is not decades away, but years away. Too close to go without a hard and fast decision to outlaw autonomous weapons, to ban them worldwide, before they cause all-out chaos. The letter is short, concise, and extremely easy to understand: artificial intelligence can make the battlefield safer, it says, or AI can make the entire world a very terrible place to live.

Researchers create transistors using a single molecule

Researchers create transistors using a single molecule

The heart of a processor inside a computer and other devices is the transistor. The more transistors that can be crammed inside a CPU, the better the device performs. There is a limit to how small a working transistor can be and a group of researchers has made a significant breakthrough in transistor size. The team was able to show for the first item that a single molecule can operate as a field-effect transistor.

Dark side of the Pluto captured by New Horizons

Dark side of the Pluto captured by New Horizons

Today NASA reveals an image of Pluto that captures the night side of the dwarf planet. Unlike our own moon, the dark side of Pluto isn't quite such a prevailing "mystery" as it rotates. We've essentially seem at least blurry images of all parts of Pluto. This image captures the dwarf planet's atmosphere. From the side of the spherical space body that's facing away from the sun at the time of image capture, this photo was taken after NASA's New Horizons mission had already completed its closest pass.

Thor robot wins 2015 RoboCup in China

Thor robot wins 2015 RoboCup in China

There are more robotics competitions around the world than you can shake a stick at. Some of these competitions have robots trying to do things like drive cars and navigate obstacles in an effort to create a robot capable of saving people in a disaster. Other competitions are more laid back and feature robots that are designed to do human things like play soccer. A robot called Thor built by researchers from UCLA and the University of Pennsylvania has won a big soccer match.

Newly discovered planet is most like Earth

Newly discovered planet is most like Earth

NASA has discovered a planet that, as far as discovered planets go, is most like Earth. The planet is called Kepler 452b, and it is the first discovered that is nearly the same size as Earth within the habitable zone surrounding a sun-like star. This marks the space agency’s latest efforts in finding an “Earth twin” — that is, a planet that is most similar to our own and that is able to sustain life. Its size and location aren't the only things Kepler 452b has in common with Earth, however.

GMO rice has high yield, cuts greenhouse gas emissions

GMO rice has high yield, cuts greenhouse gas emissions

A new genetically modified rice has been developed, and though only a single gene has been altered (in this case, borrowed from barley), it has a significantly increased yield while cutting methane emissions. The new GMO rice was tested three years in fields, and the results show it was overall effective, but particularly so when grown in the summer time, a time during which researchers saw methane emissions drop to 0.3-percent from the 10-percent that was produced by regular non-modified rice.

Fungus-grown Hair Ice proves Mother Nature as weird as ever

Fungus-grown Hair Ice proves Mother Nature as weird as ever

Get your combs out, because new Swiss research is unraveling the mysteries of what they call "Hair Ice." This beautiful natural phenomenon grows on the branches of certain types of rotten trees only under some rather specific circumstances, and only in a few places on our planet. Today's study is only the latest in a line of studies of Hair Ice, the first having taken place back in 1918 by Alfred Wegener, discoverer of palaeomagnetism and originator of the theory of continental drift.

Apple Watch sales broken down by shipments, units, and revenue

Apple Watch sales broken down by shipments, units, and revenue

Today we're breaking down all the information available to us on sales of the Apple Watch in the first quarter it's been on the market. While we can pinpoint the exact in-store date and pre-order dates for the device, these dates are irrelevant. Apple and Strategy Analytics have already given us all the information we need to get a basic assessment of the number of units sold as well as a basic outline of how much revenue Apple likely makes per Apple Watch sold.

ESO’s ALMA detects gas clouds that helped form first galaxies

ESO’s ALMA detects gas clouds that helped form first galaxies

The European Southern Observatory’s Atacama Large Millimeter/submillimeter Array, more commonly referred to as ALMA, has detected the most distant gas clouds that form stars thus far discovered in the early universe. That makes this a particularly notable observation, and will allow researchers to further understand how the very first galaxies were formed and how they cleared away hydrogen gas fog during a period known as “reionization”. Until this point, such observations were described as being simply "faint blobs".
