This new 3D printer makes life-sized ear, muscle, and bone tissues from living cells - ScienceAlert

For the first time, scientists have used a 3D printer to produce life-sized body parts and tissues using living cells as the 'ink'. Not only are these structures large and sturdy enough to be a viable replacement for the real thing - something that previous bioprinters have failed to do - they're personalised and functional, not a 'one size fits all' cosmetic add-on.

This self-filling bottle makes clean water out of thin air

An Austrian start-up has revealed plans to start selling a self-filling water bottle that extracts humidity from the air and condenses it into drinkable water at a rate of up to 0.5 litres per hour - provided it’s a really humid day.

Developed by the team at Fontus, the solar-powered device uses hydrophobic surfaces to repel and funnel the drops of condensation in the bottle, which means so...

NASA's solar-powered spacecraft Juno breaks distance record at 793 million km from the Sun

NASA's Juno mission to Jupiter has broken the record to become humanity's most distant solar-powered emissary. The milestone occurred at 11 a.m. PST (2 p.m. EST, 19:00 UTC) on Wednesday, Jan. 13, when Juno was about 493 million miles (793 million kilometers) from the sun.

New artificial skin can let robots 'feel' heat and pressure simultaneously

A team of researchers with Ulsan National Institute of Science and Technology and Dong-A University, both in South Korea, has developed an artificial skin that can detect both pressure and heat with a high degree of sensitivity, at the same time.

This new biosensor can detect water contamination as it happens - ScienceAlert

Right now, detecting contaminated water can take days, and that puts humans and animals at serious risk. But a new biosensor developed by grad students in Denmark promises to spot unclean water in an instant, and whether it's used in a village well in a rural community or a huge food production factory in the city, being able to spot contamination without lab tests or technical experts ensures the problem is caught before it has the chance to do damage. 

The Marines Are Sending Google's Robotic Dog Into Simulated Combat

US Marines are testing out Spot, a robo dog built by Boston Dynamics to see how helpful the ‘bot could be in combat. The subject of the tests was Boston Dynamics' Spot robot, a 160-pound, hydraulicly actuated quadruped robot first revealed by the Google (soon to be Alpahbet) subsidiary in February.

An Australian student has reportedly smashed NASA's fuel efficiency record - ScienceAlert

An Australian university student has reportedly developed a new kind of ion space drive that absolutely obliterates NASA's current fuel efficiency record.

Ion drives are propulsion systems that basically work by throwing particles backwards really, really fast in order to propel a spacecraft forward. NASA's current record holder for fuel efficiency is its High Power Electric Propulsion, or HiPEP, system, which allows 9,600 (+/- 200) seconds...

Researchers use Japanese art to develop solar cells that can track the sun across the sky increasing efficiency by 40%

By borrowing from kirigami, the ancient Japanese art of paper cutting, researchers at the University of Michigan have developed solar cells that can track the sun. A flat plastic sheet backing the solar cells splits into wavy, connected ribbons when stretched. The tilt of the cells depends on the stretching, a simple mechanism for tracking the sun across the sky.
