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 sends astronauts into the sea for Mars training mission

NASA sends astronauts into the sea for Mars training mission

NASA’s NEEMO 21 undersea training mission has started, the space agency announced today. Officially called the NASA Extreme Environment Mission Operations 21, the expedition lasts for 16 days and subjects astronauts to the kind of conditions they could expect to endure on a long space mission. It’s yet another piece of NASA’s Mars puzzle, not only preparing astronauts for such a future mission but also lending more data to the space agency for refining future plans.

Simple pasteurization ‘add-on’ gives milk a 63-day shelf life

Simple pasteurization ‘add-on’ gives milk a 63-day shelf life

Depending on how it is treated, delivered, and stored, milk can have a shelf life as low as a couple days and as high as a couple of weeks. A new method for pasteurizing milk, though, has resulted in milk that stays good for more than two months, potentially providing a way for one of the world's dietary staples to stay good for much longer without changing how its tastes, its texture, or its color.

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.

3D-printed fingerprints may help police access locked phones

3D-printed fingerprints may help police access locked phones

Law enforcement isn't happy about the rise of biometric phone security -- that is, fingerprint sensors -- because it is incredibly hard to bypass. To get around the pesky issue, police have turned to 3D-printing, requesting a lab recreate and 3D print a phone owner's fingerprints in a way that they can be used to unlock the phone. Though the 3D-printed fingerprints haven't yet been verified as functional, the issue has already raised a new round of criticism and privacy concerns.

Big surprise, hardly anybody is buying smartwatches

Big surprise, hardly anybody is buying smartwatches

Smartwatches may have been heralded as the Next Big Thing in consumer tech, but a stagnating market has seen the segment shrink dramatically compared to last year. Shipments overall drooped 32-percent in Q2 2016, according to the latest IDC worldwide smartwatch report, torpedoed for the most part by dwindling demand for the Apple Watch.

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.

China slams brakes on autonomous car public testing

China slams brakes on autonomous car public testing

Public testing of autonomous cars in China has been put on hold, with regulators insisting automakers must wait until the government has figured out the necessary regulations. Several self-driving vehicle projects are underway in the country, but the moratorium means that, for now, prototypes can only be trialled on private facilities.

DARPA CHIPs program seeks miniature, modular ‘chiplets’

DARPA CHIPs program seeks miniature, modular ‘chiplets’

DARPA has a new program called CHIPS, which is short for Common Heterogenous Integration and Intellectual Property Reuse Strategies Program. A mouthful, right? CHIPS seeks innovation as complex as the name behind the acronym: the taking of modern printed circuit boards and doing away with them via the development of miniature, modular “chiplets.” Says DARPA, it wants “an entire PCB” to be condensed down into a single device that is about the size of one present-day chip.

NASA atmosphere study: two exoplanets could possibly support life

NASA atmosphere study: two exoplanets could possibly support life

NASA says a pair of exoplanets may have habitable atmospheres based on an atmospheric study researchers recently performed. The scientists focused on exoplanets similar in size to Earth that are described as being ‘temperate.’ The study was done using the Hubble Space Telescope, and found that the exoplanets TRAPPIST-1c and TRAPPIST-1b have atmospheres that could possibly support life.

Will car-sharing and self-driving cars kill congestion? It’s not so simple

Will car-sharing and self-driving cars kill congestion? It’s not so simple

Car sharing and autonomous vehicles are widely expected to cut road congestion, but the future for drivers may not be so clear cut, according to two new studies released this week. The impact of alternatives to individual car ownership is still fairly uncertain, particularly as the long-term market viability of self-driving vehicles remains mired in legal, ethical, and technological questions, with the potential for traffic jams to initially get worse, not better.

Facebook may have cracked the big laser-drone internet problem

Facebook may have cracked the big laser-drone internet problem

Facebook is exploring ways of delivering internet connectivity via lasers, developing a new receiver technology that promises to be less complex and more affordable than current systems. Dubbed free-space laser communication, Facebook's break-through is in an all-new optical detector that - unlike existing examples - would neither require mechanical stabilization, nor expensive micro-motors, sensing, or processing.
