Modern Mars is a desolate husk of a planet, as far as life is concerned. But it’s not completely uninhabitable, since microbes could be hiding in the cracks of rocks and dirt. And now a new study has found a possible food source for these organisms – space dust.

A study has followed thousands of teenagers tracking associations between screen time and depression. The research separated types of screen time, and found TV and social media activity correlated with increased symptoms of depression, but video game and computer use had little negative effect.

​Last year, Italy's Samuel Mello Medeiros hit Kickstarter with a chunky add-on that gave old 35 mm cameras a new lease of digital life. Now he's returned with a camera back that performs similar magic on classic medium format cameras like those from Hasselblad, Mamiya and Zenza Bronica.​

Not a lot has been revealed since Elon Musk announced his Neuralink venture two years ago, but the company today emerged from the shadows to share its progress so far, along with its plans for the future, which involve implanting its first chips in human as early next year. ​​

A compelling new study has described a novel association between viral infections, neurodegenerative disease, the gut microbiome, and our immune system. The research suggests gut bacteria disruptions can allow harmful viruses to trigger neurological diseases such as multiple sclerosis.

Bluetooth keyboards are great when you need to type on a tablet, but a built-in trackpad would be useful. Rather than bulk out the form factor, Belarus-based Clevetura is launching a keyboard that turns the keying area into a touch-sensitive trackpad when the user isn't typing.

The LIGO detector uses 4-km-long (2.5-mi) arms. But now, a Northwestern University team is aiming to build a gravitational wave detector small enough to fit on a tabletop, which could detect signals the larger facilities miss.

For working musicians, interacting with your audience is an important part of playing live. And so is getting paid. Phil the Tip Jar is fun and quirky and gives something back to fans, dispensing "thank you" cards when it detects money going in the top.

​As compared to most other joints in the human body, the knee has quite a large range of motion … so why not put that motion to use, as a source of electricity? That's what a new prototype device does, and it reportedly does not cause its wearer to expend more energy while walking.

​If you're a member of a rowing team, it's not just your stroke that's important, but also how well you coordinate that stroke with those of your team-mates. With that in mind, Idaho-based rowers Mike Schaefer and John Balint invented the connected and collaborative Stroke Master rowing machine.

​The shorter a drone's propellers, the less efficient they are at keeping it airborne. That factor, along with compact, low-capacity batteries, is the reason that small drones can't fly very long. A new two-prop drone, however, is claimed to deliver twice the flight time as same-sized quadcopters.

A new drug delivery system has been developed that hides chemotherapy molecules inside fat cells that are quickly eaten up by hungry tumors. The method has been shown to be effective at targeting bone, colon and pancreatic cancers in animals, and human trials are proposed for the near future.
