July’s once in a blue moon: rare ‘extra’ moon visible tomorrow

July’s once in a blue moon: rare ‘extra’ moon visible tomorrow

Tomorrow brings with it a blue moon, which, you may be disappointed to find out, isn’t actually a blue-colored moon. Rather, it is an “extra” full moon that only happens in some years, hence the term, “Once in a blue moon”. This year, 2015, is one of the special years with an extra full moon, in that every month has had (and will have) one full moon, which is typical, with the exception of July. In total, 2015 will have had 13 full moons instead of 12.

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.

First aurora outside Solar System spotted on a brown dwarf

First aurora outside Solar System spotted on a brown dwarf

Auroras. Borealis in the north, Australis in the south. Who would have thought that finding that same beautiful phenomenon on a celestial body outside our solar system would lead to much excitement. But that is exactly what the brown dwarf LSR J1835 provided astronomers. Located in the Lyra constellation 18 light years away, the small star/big planet exhibited the equivalent of the Aurora, though red in color compared to our own Earth's green. The thing is, that occurrence has never been recorded outside our Solar System.

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.

Lexus teases hoverboard again, promises full reveal on August 5

Lexus teases hoverboard again, promises full reveal on August 5

It was almost a month ago exactly that out of the blue Lexus released a video showing off a "real, rideable hoverboard." With a design and shape clearly inspired by a skateboard, little else was shown in the teaser, with an abrupt ending as someone approached the hoverboard and was just about to put their foot on it. Well, the hoverboard, simply called Lexus SLIDE, has made another appearance in video form, with Lexus promising more details on August 5th.

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.

Watch an effervescent tablet fizz inside a ball of water in space

In space even, the mundane and boring things we do when we don’t feel so well on Earth are exciting and worth of recording with a super expensive RED 4K camera. If you happen to have a 4K monitor I strongly suggest that you hit up YouTube change the resolution of the video below to 4K and check this out. The video shows a ball of water floating weightlessly in space aboard the ISS.

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.

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.
