Mercury shrinking NASA confirms: 4.3 miles in 4bn years

Mercury shrinking NASA confirms: 4.3 miles in 4bn years

Mercury is shrinking, its radius reduced as much as 4.3 miles over the past four billion years, scientists have confirmed, with the planet contracting as its iron core cools. The gradual reduction had been expected but unconfirmed until NASA's Messenger spacecraft beamed back photos of Mercury's surface, with previous - incomplete - footage of the closest planet to our sun showing far less shrinkage than the models predicted.

Big Bang breakthrough as Cosmic contractions spotted

Big Bang breakthrough as Cosmic contractions spotted

A "spectacular" discovery that could explain the Big Bang that created the universe and potentially lead to Nobel prizes for the researchers behind it is prompting excitement in the scientific community, concerning the sudden "inflation" rush in growth in the very first moments of cosmic expansion. Inflation as a theory concerns the initial growth of the universe - measured as a trillionth of a trillionth of a trillionth of a second - fourteen billion years ago, and an American team now says it has identified the lingering remnants of it.

Chernobyl fall-out slammed brakes on nature says study

Chernobyl fall-out slammed brakes on nature says study

It's been around three decades since the Chernobyl nuclear disaster occurred and the meltdown caused massive evacuations. While effects on the human body and mind are still being contemplated, new studies suggest that the ecosystem around the failed facility may be more affected than believed, with the decaying plant matter left behind not decomposing optimally and indicating significant impact on the natural cycle.

US outdoes Japan and China for mobile data demand

US outdoes Japan and China for mobile data demand

We are a data hungry country and we have the numbers to prove that. The US is on track to cross the $100 billion mark for revenue stemming from mobile data, according to analyst Chetan Sharma. You can say that it’s finally getting set in stone, that people are moving from the desktop to more mobile options like the smartphone and tablets.

Crowdsourced Moon maps get accuracy approval

Crowdsourced Moon maps get accuracy approval

Crowdsourcing already gets products off the ground and figures out where traffic congestion is, but CosmoQuest is turning the power of group-work to map the moon. Using high-resolution images beamed back from NASA's Lunar Reconnaissance Orbiter (LRO), the public science project allows anybody to register and then sift through, flagging up craters, boulders, and other features of the rocky surface. Now, new research indicates the crowdsourced mapping can be just as accurate as when trained experts do it.

Roadrage car tech tracks if you’re dangerous

Roadrage car tech tracks if you’re dangerous

Cars that can recognize when drivers are angry or irritated, and warn when emotional states might make them dangerous on the road, are in development in France, using dashboard cameras to track facial expressions associated with roadrage. The technology - which could, researchers suggest, be paired with lip reading AIs that could pick up on times when you cuss out the driver who cuts in front of you - initially reacts to expressions of anger or disgust.

Tiny fluffy T-Rex roamed the Arctic

Tiny fluffy T-Rex roamed the Arctic

A new species of pygmy Tyrannosaurus Rex only half the size of its closest relative has been identified in northern Alaska, with Nanuqsaurus hoglundi ending up smaller and fluffier than its better-known cousins thanks to the harsh conditions. The dinky dino was likely the top Arctic predator in the late Cretaceous period, paleontologists Anthony R. Fiorillo and Ronald S. Tykoski concluded, measuring around 20 feet long and probably covered in dense fuzzy hair.

Samsung Galaxy backdoor could pose data risk [Updated]

Samsung Galaxy backdoor could pose data risk [Updated]

Multiple models of Samsung Galaxy smartphones could contain a backdoor for remote data access, a developer team has alleged, potentially leaving personal files open to clandestine browsing. The security loophole stems from a proprietary app Samsung created to run on the modem's application processor, which can access and modify software running on the phones and, in at least nine cases, have unfettered access to personal data as well.
