A team of researchers at Pennsylvania State University, led by Amanda D. Hanford, has developed a “cloaking device” that works underwater. The new metamaterial shield is able to intercept and bend underwater sound waves, like sonar, around it without scattering them – making it appear as if the cloak and anything within it isn’t there at all. read more

Google has just announced its flagship phones for 2018 – the Pixel 3 and 3 XL – which means all your best options for the year are now on the table. If you’re considering one of the latest Pixels, the main question you’re probably asking yourself is how well they stack up against the other key players – specifically, Apple’s new iPhones. To help you decide, New Atlas compares the specs and features of the Google Pixel 3 and 3 XL to the iPhone XR, XS and XS Max. read more

Just a few weeks ago Samsung unveiled the Galaxy A7, kitted out with four cameras. Not to be outdone, LG has now upped the stakes with a new premium phone that’s almost more camera than phone. The LG V40 ThinQ sports no less than five lenses – two in the front and three in the back – bringing with it a bevy of new photography tricks and good internal specs to boot. Oh, and the company has a new watch too. read more

In more bad news for future voyagers to Mars, a team of scientists at the Georgetown University Medical Center (GUMC) has found the kind of Galactic Cosmic Radiation (GCR) that astronauts will encounter on long space voyages can cause heavy damage to their gastrointestinal (GI) tract. read more

Manufacturers go to great lengths to make their motorcycles as safe as possible and usually the task is handled by electronics, such as traction control, cornering ABS and electronic suspensions. Apparently, no one had thought to employ rockets to help a bike stay upright. Until Bosch, that is. read more

Lockheed Martin has taken the wraps off its vision for a future manned lunar lander at International Astronautical Congress (IAC) in Bremen, Germany. The concept spacecraft is designed to show how a reusable lander, in conjunction with NASA’s planned lunar Gateway deep-space orbital outpost, can support an indefinite human presence on the Moon as well as providing valuable experience for the first manned missions to Mars.

It’s been almost half a century since the last astronauts set foot on the Moon and with new US plans committing NASA to a program of sustained human exploration and exploitation of deep space, returning to the lunar surface will involve much more than simply taking up where Apollo left off. Not only has technology advanced considerably since the 1960s, but making more than temporary and sporadic visits to the Moon and beyond requires a whole new approach to space exploration. read more
