Soft finger-like robots can sweat to cool down just like humans

Robots are becoming more human-like every day: now they can sweat. By Donna Lu Read more: https://www.newscientist.com/article/2231859-soft-finger-like-robots-can-sweat-to-cool-down-just-like-humans/#ixzz6FcG6T8Eb Thomas Wallin at Cornell University in New York and his colleagues have created soft robotic grippers that are capable of sweating to cool down. The grippers are capable of a cooling capacity of 107 watts per kilogram, making them more efficient […]

A fingerprint can show if someone has taken cocaine or just touched it

A single fingerprint can distinguish whether someone has recently touched cocaine or actually ingested it. This test can be completed in less than 2 minutes, far quicker than blood tests, and could be used for forensic investigations or drug testing.

Tech heaven: Drone academy students help map out Africa’s future

Eldson Chagara https://www.reuters.com/article/us-malawi-drones/tech-heaven-drone-academy-students-help-map-out-africas-future-idUSKBN1ZT0Y9 Now, as a student at Africa’s first drone academy, she is about to make it come true. The institute is in Malawi, and builds on the work of a pilot scheme launched in 2017 with support from U.N. children’s fund UNICEF, in which drones have been used to deliver medical supplies, monitor […]

3D-printed bunny contains DNA instructions to make a copy of itself

A 3D-printed polyester rabbit has been embedded with DNA that contains a blueprint for printing additional bunnies. Using the information, researchers have replicated the rabbit several times, highlighting the potential for using DNA to store information in everyday objects.

Driverless cars and the other biggest sci and tech fails of the decade

Whether it was driverless cars, lab-grown meat or faster-than-light neutrinos, some things just didn’t live up to the hype in the 2010s SPACE 18 December 2019 Read more: https://www.newscientist.com/article/mg24432613-900-driverless-cars-and-the-other-biggest-sci-and-tech-fails-of-the-decade/#ixzz6CEN8Rht7 Self-driving cars This was meant to be the decade of the self-driving car, as governments began permitting testing on public roads. But you can’t hang up your steering wheel […]

A new battery could keep your phone charged for five days

A new lithium-sulphur battery with an ultra-high capacity could lead to drastically cheaper electric cars and grid energy storage. By Donna Lu Read more: https://www.newscientist.com/article/2228681-a-new-battery-could-keep-your-phone-charged-for-five-days/#ixzz6CEMWqwmp Mahdokht Shaibani at Monash University in Melbourne, Australia, and her colleagues have developed a battery with a capacity five times higher than that of lithium-ion batteries. The battery maintains an efficiency of 99 per […]

Captured carbon dioxide could be used to help recycle batteries

Captured carbon dioxide could be used to extract useful metals from recycled technology such as smartphone batteries rather than just being buried underground. The technique could help make it more economical to capture the greenhouse gas before it enters the atmosphere. By Michael Marshall Read more: https://www.newscientist.com/article/2229866-captured-carbon-dioxide-could-be-used-to-help-recycle-batteries/#ixzz6CELvPoX8 “By simultaneously extracting metals by injecting CO2, you add value […]

A robot equipped with real pigeon feathers flies like a living bird

A robot that resembles a pigeon and can make tight turns like real birds may point to the future of aerospace engineering – a continuously morphing wing. By Jason Arunn Murugesu Read more: https://www.newscientist.com/article/2230401-a-robot-equipped-with-real-pigeon-feathers-flies-like-a-living-bird/#ixzz6CELCmmix Understanding exactly how birds fly has always been tricky, because individual wings are made up of multiple feathers. These feathers are always interacting with each […]
