Bold Mission to Hunt for Aliens on Venus Is Happening

A UK-based mission is aiming to settle, once and for all, whether life exists on Venus. The mission plans to send a probe to the planet in search of microbial life, not on the surface, of course, but in the Venusian clouds. Over the past half-decade, scientists have detected the presence of phosphine and ammonia—two potential signs of biological activity—in Venus’s clouds. On Earth, both gases are produced only by biological activity and industrial processes, and scientists are unsure of their

The fish kick may be the fastest subsurface swim stroke yet (2015)

I tug my black swim cap over my hair, strap on my pink goggles, and keep a focused calm, like Michael Phelps before a race. It’s lap swim on a Monday afternoon at my local YMCA, and I’m going to attempt the fish kick. Most fish move through the water with a horizontal wiggle. The fish kick challenges you to copy this movement: You completely submerge yourself underwater, position yourself on your side, keep your arms tight above your head in a streamline, and propel yourself forward with symmetr

Major reversal in ocean circulation detected in the Southern Ocean

Satellite data processing algorithms developed by ICM-CSIC have played a crucial role in detecting this significant shift in the Southern Hemisphere, which could accelerate the effects of climate change. Thanks to data obtained from Earth observation satellites, an international team of scientists has detected an unprecedented phenomenon for the first time: a reversal in the ocean circulation of the Southern Ocean. The study, led by the National Oceanographic Center (NOC, United Kingdom), was r

Robotic sucker can adapt to surroundings like an actual octopus

Some of the most ingenious tech has been inspired by nature. From color-changing materials that function like cephalopod skin to a tiny biomimetic robot that looks and moves like an actual cockroach, the extraordinary adaptations of some organisms have upgraded our technological capabilities. Now the octopus is lending an arm—or a sucker. Octopus tentacles have remarkably strong suckers with an adhesion power that could be an asset to soft robots that need to pick things up and hold onto them.

13-inch Microsoft Surface Laptop review: A slightly worse version of a year-old PC

Microsoft's new 13-inch Surface Laptop is an odd one. It's inarguably a step down in every respect from last year's 13.8-inch Surface Laptop. But it's also too good (and too expensive) to be considered a replacement for the Surface Laptop Go, the company's perennially overpriced and underspecced entry-level laptop. It's cheaper than last year's Surfaces, but mostly because Microsoft gave those devices a de facto price hike by killing the entry-level configurations of those PCs. We're left with

I recommend this Windows tablet for work travel over the iPad Pro - and it's on sale

Something Big Is Twisting Mercury’s Crust

Mercury has it rough. Not only is it the smallest planet in the solar system, it’s also the closest to our Sun. This unfortunate position has caused Mercury to develop cracks and fractures across its surface, and generate stresses to its crust, a new study has found. Mercury is dry, rugged, and heavily cratered; the planet appears deformed with towering cliffs and ridges, as well as fracture lines that run along its surface. The origin of Mercury’s scars has long been a mystery: How did the pla

I Tried Hear.com's At-Home Prescription Hearing Aids Test

Putting aside their exorbitant cost, the trouble with prescription hearing aids is the prescription. Find a doctor. Get an appointment. Sit in a waiting room. Suffer through an hour of testing before getting the hard sell on a pair of hearing aids. Why, the indignity of it all is even worse than going deaf. Telehealth offers a glimmer of a solution, but as everyone who’s tried to show off a concerning mole to a doctor via a smartphone camera knows: Video technology can only get you so far. Audi
