Think exceptional sight would be a cool superpower? You’re in luck: Researchers from the University of Minnesota have built a bionic eye prototype that could restore sight to the blind and give superhuman vision to those who can already see. - by Ashley Braun - 08/31/2018

Australia’s Great Barrier Reef can’t catch a break: on top of contending with pollution, hurricanes, and back-to-back-to-back bouts of coral bleaching, the world’s most iconic reef is being eaten alive by millions of prickly, venomous sea stars known as crown-of-thorns starfish (COTS). But in a matchup befitting a sci-fi movie, scientists have developed a new robot to hunt and kill these sea stars—a murderous, autonomous underwater vehicle called RangerBot.

Liquid printing is virtually ubiquitous thanks to inkjets, but the materials can only be so sluggish before it stops working. What if you wanted to print a biological material, or even liquid metal? That might happen soon. Harvard researchers have developed a technique that uses acoustic levitation to print droplets of materials that wouldn't normally be so accommodating, including metal and honey. The approach uses a subwavelength acoustic resonator to create a sound field that pulls substances from the printer nozzle at over 100G -- even some of the most viscous materials can't resist that tug. You can control the size of the droplets using the amplitude of the soundwaves, and place them anywhere you like.

A fold-up computer screen has been unveiled by a group of researchers in Canada. Dubbed the ‘MagicScroll’ it’s being billed as the world’s ‘first rollable tablet PC’. The flexible display unrolls from around a cylindrical spindle into a 7.5-inch that can then be laid flat. There are two rotary wheels on each end that allow a user to unroll the display and scroll through contacts on the display. It can still be used when it’s rolled up, such as for making a phone call one-handed.

A sapphire-colored dye called methylene blue is a common ingredient in wastewater from textile mills.

But University at Buffalo scientists think it may be possible to give this industrial pollutant a second life. In a new study, they show that the dye, when dissolved in water, is good at storing and releasing energy on cue.

The magicians at MIT have come up with another solution to one of the world's science problems.

On Tuesday, MIT Media Lab shared new technology for communication from underwater to the air, a feat not previously possible.

That's because submerged submarines cannot wirelessly communicate with an airplane. The communication mediums don't match up: Submarines use sonar, while airplanes use radio signals, cellular or GPS. Sonar signals reflect off the water surface without breaking through, and radio signals don't travel well through water.

But MIT has the answer.

A ban on halogen light bulbs will go into effect in the European Union on September 1, 2018, encouraging consumers across Europe to switch over to the more energy-efficient light-emitting diodes, or LEDs.
