As always, the value of Bitcoin (BTC) rises and falls, and with it, media coverage. The cryptocurrency clawed its way into the public eye months ago when it reached an all-time high of around $ 250 per coin, then crashed hard and faded from view like it always has. Now, Bitcoin is back thanks to its recent ridiculous surge beyond ...

Mars is the planet right next door, and we’ve shot a dozen probes and rovers its way in the last few decades. However, there’s still a lot we don’t know about the Red Planet, and the MAVEN probe could help solve some of those mysteries. MAVEN stands for Mars Atmosphere and Volatile EvolutioN (okay, NASA), and its goal is to ...

The PlayStation 4, which is released today, is an odd proposition. On the one hand, it only costs $ 400 — but on the other, you really don’t get a whole lot for your money. The launch games for the PS4 are a mixed bag, with the PS4-exclusives Killzone: Shadow Fall and Knack really not strong enough to justify the ...

The unremarkable Chevrolet Spark, gasoline edition, becomes a desirable, almost cheap urban commuter car when you swap in an electric motor. What’s more, with the Spark EV, the smartphone-based navigation starts to fulfill the promise of significant apps running off your phone and streamed to the car’s LCD display. With the gas-powered Spark, people say, “It’s easy to park and ...

On July 17, did you look up and smile? If not, you’re one of several billion people who were captured in candid pose when NASA’s Cassini space probe looked back at Earth from about 1.5 billion kilometers (932 million miles) away. Cassini has always been able to flip around and snap pictures in Earth’s general direction, but this picture was ...

For over a decade, portable fuel cells makers have been promising that they were about to become economical for mobile and remote applications. California-based Jadoo pioneered in the field, with a solution aimed at on-site TV crews and medical applications, but its products never achieved broad success. More recently, smaller units like the MyFC PowerTrekk have entered the market, catering ...

Gas, diesel, hybrid, or electric? Everyone wants their next car to have better fuel economy and wouldn’t mind if it’s better for the environment. But which engine is the right choice? Ultimately, it depends on the kind of driving you do and how much distance you’ll travel before turning the car over to the next owner. This auto tech backgrounder ...

Last year, news broke that a virus sabotaged the Iranian uranium enrichment program. It seemed all too convenient at the time — and as it turned out, the virus, Stuxnet, was actually engineered by the United States and Israel. Now, the man-made virus has ventured into space, and made its way to the International Space Station. The virus wasn’t planted ...

A Swedish company has launched the OrbSys recycling shower — a new kind of shower that saves up to 90% of the water and 80% of the energy consumed by a normal shower. The shower achieves such huge savings by being a closed-loop, recirculating system, much in the same way that astronauts aboard the International Space Station re-use their waste ...

A few years ago, carbon nanotubes (CNTs) were touted as the Wave of the Future that would revolutionize materials engineering from semiconductors to space elevators. These days, CNTs have largely been obscured by the mad rush to research graphene (though not entirely), but there’s still some work being done on nature’s version of the ultimate Fruit Roll-up. This week, scientists ...
