Sub shows Antarctic ice not as thin as we thought

Sub shows Antarctic ice not as thin as we thought

When we discuss the overall health of our planet, we typically have to entertain the idea that ice is melting at a rate quicker than we’re comfortable with. The way we currently measure ice is via satellite flyovers and boring through ice caps, which doesn’t give as accurate a picture as we’d like. A new submarine, dubbed SeaBED, is taking much of the work below the surface. The unmanned sub sends a sonar blast from the bottom, and what we’re learning is that ice caps may not be as thin as we’d imagined.

This little rover thinks it’s time we went back to the moon

This little rover thinks it’s time we went back to the moon

The attentions of the space-faring industry may have turned to more distant targets, like Mars or even hurtling comets, but that's not to say there's not still room to explore a closer neighbor, like our own moon. Carnegie Mellon has revealed the robotic rover it believes will not only clinch it part of a $20m+ Google Lunar XPrize, but discover new and unseen pits and caves that pock the moon's surface. Dubbed Andy, the robot is predominantly the handiwork of students, and took just nine months to develop.

New footage shows Antares rocket explosion from the ground

New footage shows Antares rocket explosion from the ground

Late last month, the unmanned Antares rocket launched. Shortly after lift-off, a problem occurred, and there was an explosion that sent the rocket back to earth. When Antares hit the ground, a second and much more jarring explosion took place, destroying the rocket and damaging much of the structure surrounding it. On the ground were a few cameras, put there to record a successful launch. Now that the cameras have been recovered, we get a first-hand shot of what a rocket explosion really looks like from near the launch pad.

Face to face with the Devil: Rare anglerfish caught on tape

Face to face with the Devil: Rare anglerfish caught on tape

Coming face to tooth-filled face with a deep-sea anglerfish that's more mouth than anything else might not seem like something to celebrate, but it's different when it's one of the first times the fish has been caught on camera. Usually the small predators - which use a bioluminescent lure suspended over their heads to attract prey - are only found at depths of around 2,000m, but researchers stumbled unexpectedly on a Black Sea Devil at around 580m in Monterey Bay, California after discovering it with their remote-controlled sub, dubbed Doc Ricketts.

Nestle details “exercise in a bottle” research

Nestle details “exercise in a bottle” research

Nestle is working on the Holy Grail of weight loss, a fat-burning additive that could be dropped into foods and replicate the effects of exercise but without the sweaty reality of doing it. The team, based at the Swiss Federal Institute of Technology in Lausanne, is exploring how a new compound dubbed C13 could be used in food to stimulate the enzymes which control how the body burns fats and sugars. If tweaked in just the right way, Nestle says, that could mean a new age of foods which would allow the body to get the same fitness benefits from a brisk walk as would normally take much more strenuous exertion.

Germany’s Sunfire makes synthetic gasoline from water, CO2

Germany’s Sunfire makes synthetic gasoline from water, CO2

While vehicles like Toyota's fuel-cell powered Mirai are leading the charge to a future less reliant on fossil fuels, Germany's Sunfire GmbH may have a way to bridge the gap with its method of producing synthetic fuel from water and carbon dioxide. By using two of the world's most abundant elements to create hydrocarbon fuel, a much great efficiency over fossil fuels can be achieved.

VetiGel is a plant-based gel that can stop bleeding instantly

VetiGel is a plant-based gel that can stop bleeding instantly

When a massive injury occurs, and there’s bleeding involved, time is essential. Often times, emergency medical personnel are on-scene, but have little recourse to do more than get you somewhere else quickly. A place that has the equipment necessary to help you get through the trauma and (hopefully) live. A new syrum, named VetiGel, could change that. The plant-based material can be affixed to human tissue to stop bleeding rapidly. It’s not yet widely available, but is being trialled at veterinary clinics.

This watch has a real laser inside — a REAL laser!

This watch has a real laser inside — a REAL laser!

How many times in a day do you think “man, a laser would come in super handy right now”? If you’re like me, probably half a dozen or so (alright, so, mainly I wish I had a pen light to torture the cat, but still). If you’re a James Bond fan, you might even wish that laser was mounted to a watch, and you could burn ropes typing you down, or like seal a bag of chips on the fly. That’s getting closer to reality for you and I, as one tinkerer has created a laser-enabled watch.

AOptix’s laser-radio tech could be Internet’s future

AOptix’s laser-radio tech could be Internet’s future

The ubiquity of mobile devices is starting to push the limits of the Internet's infrastructure to the breaking point. Add that to the fact that a lot more regions don't have quality connections or don't have Internet at all, and you have a scenario where service providers are scrambling to add more and more cables, especially fiber optic ones, on land and on sea. But such installations cost time, money, and, in some cases, political will. AOptix's solution is cheaper as it uses a combination of laser and radio waves to bring the Internet anywhere.
