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.

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.

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".

Pluto: second icy mountain range revealed in new image

Pluto: second icy mountain range revealed in new image

Last week, NASA's New Horizons spacecraft gave us some up-close, detailed images of Pluto's landscape and geology, including a look at an icy mountain range. Now, only a few days later, NASA has released another image that reveals a second mountain range, with peaks between half a mile and one mile in height. The range is located near the southwestern part of Pluto's now famous heart-shaped spot, about 68 miles from Norgay Montes, the first mountain range that was photographed.
