Titanium-gold alloy makes ultra-hard artificial joints

Titanium-gold alloy makes ultra-hard artificial joints

Researchers have developed a new type of alloy that is said to be four times harder than most type of steel, the end goal being artificial joints that are harder and more durable. In the present day, titanium is the preferred type of metal for these artificial joints. In the future, though, a titanium-gold alloy may be used instead, with the mixture being about three parts titanium to one part gold. The alloy is four times harder than titanium.

NASA puts Groot and Rocket Raccoon on official space station patch

NASA puts Groot and Rocket Raccoon on official space station patch

Groot and Rocket Raccoon, the talking racoon and tree from Marvel's Guardians of the Galaxy, are becoming a part of official NASA history. The pair have been chosen by space agency to adorn this year's mission patch for the International Space Station's National Laboratory. The adorable patch was revealed by the Center for the Advancement of Science in Space (CASIS) at San Diego Comic-Con.

New NASA Goddard video shows one year time-lapse of Earth from space

New NASA Goddard video shows one year time-lapse of Earth from space

There have been a lot of developments concerning space lately, whether we're talking about the study of exoplanets or catching glimpses of protoplanetary disks around young stars. Sometimes, though, it's nice to be reminded of back home, our pale blue dot that is floating through this same universe that offers so much in the way of scientific discovery. A new video from NASA Goddard is doing just that, using photos from the EPIC camera on NOAA's DSCOVR satellite.

Curiosity rover can now choose some targets autonomously

Curiosity rover can now choose some targets autonomously

Now that the Curiosity rover has been cruising around on the surface of Mars for a long time, NASA is giving the machine the ability to choose some of its own targets for more study. Curiosity is now able to select rocks to target its laser spectrometer on autonomously. NASA says that this is the first time that an instrument of this kind has been autonomously operated on any robotic planetary mission.

Humans adapted to survive car wrecks are terrifying

Humans adapted to survive car wrecks are terrifying

Imagine if humans evolved in such a way that we could better handle being in a car crash. It would involve some big changes, as you can imagine; necks, spines, and ribs are particularly vulnerable and often injured in car wrecks, for example. Thanks to a trio of industrious folks, we get a glimpse at what one of those evolved humans may look like. Hint: it’s horrifying. Apparently to withstand car crashes, humans will need to transform into a real-life Juggernaut.

Researchers map another 180 areas of the human brain

Researchers map another 180 areas of the human brain

A research project funded by the National Institutes of Health has identified 180 new distinct areas of the human brain, specifically of the brain’s outer mantle. According to the NIH, this number is more than double that of the previously mapped brain areas. In addition to identifying these new regions, the researchers behind it also created a new type of software able to find each of these areas’ ‘fingerprints’ automatically, doing so using brain scans.

NASA study shows global surface temps are setting records in 2016

NASA study shows global surface temps are setting records in 2016

NASA is continuing to conducting its studies on two key indicators of surface temperatures around the globe. Those two key indicators are global surface temperatures and Arctic sea ice extent. According to NASA during the first half of 2016, each of the six months set a record as the warmest respective month globally. Those records are compared to when the modern global temperature recording began in 1880.

Elon Musk wants to land three rockets at the same time

Elon Musk wants to land three rockets at the same time

Now that it has a few successful rocket landings under its belt, including two on land, SpaceX is moving on to the next ambitious goal: landing more than one rocket "almost" simultaneously. This surprising revelation was made, and confirmed by Elon Musk himself, when the space travel company was reported to be seeking approval for two additional landing pads on Florida's Space Coast in order to indeed land the three rockets of a Falcon Heavy rocket within just minutes of each other.

Researchers use nanoparticles to make a round object appear flat

Researchers use nanoparticles to make a round object appear flat

We’re still waiting for someone to create a proper Harry Potter-like invisibility cloak, but in the meantime researchers have used nanoparticles to ‘cloak’ the shape of an object. The work was done by researchers at the Queen Mary University of London’s School of Electronic Engineering and Computer Science; with their newly created system, a curved object like a ball appears to be flat when detected by electromagnetic waves.

NASA spots two potentially life-supporting alien planets

NASA spots two potentially life-supporting alien planets

Two freshly-identified planets could feasibly support life, NASA's Jet Propulsion Lab has concluded, the latest crop of Earth-like possibilities spotted by the Kepler Space Telescope. Though 181 light years away from our own Earth, the two new discoveries are half of a quartet of "promising" planets that could be rocky, among other life-sustaining criteria.

World’s smallest hard disk can fit all of humanity’s books on a stamp

World’s smallest hard disk can fit all of humanity’s books on a stamp

Researchers with the Kavli Institute of Nanoscience at Delft University have created a new “smallest” hard disk, this time using a system where a bit of data is created by positioning one chlorine atom. It now holds the distinction of being the smallest hard disk in the world, though if history proves true, we’ll be seeing someone else break this record soon enough. According to one of the researchers, using this method the entire world’s library of books could be written to one postage stamp.

NASA imagines landing on Pluto’s surface in new video

NASA imagines landing on Pluto’s surface in new video

This month celebrates the one year anniversary of New Horizons' visit to Pluto, everyone's favorite dwarf planet. Launched back in 2006, New Horizons was our first opportunity to get up close and personal with Pluto, and even though the flyby was a brief one, the pictures and measurements New Horizons was able to capture are awe-inspiring. To celebrate the one year anniversary of the flyby, NASA is imagining what it would be like to land on the surface of Pluto with a new video that strings together more than 100 images from the New Horizons mission.
