After taking to the air for the first time last year, Klein Vision's AirCar has now aced its first inter-city flight – taking off from Nitra airport, landing in Bratislava some 35 minutes later, and then heading into the Slovakian capital by road.

Volvo is laying out an ambitious calendar in moving toward becoming an all-electric premium car brand. As previewed by the new Concept Recharge, its next-gen electric vehicles will push for longer ranges, faster, bidirectional charging and more tech.

Amber is amazing at preserving insects and small creatures, but now it might have some competition – fossilized feces. A hapless beetle has become the first species discovered and described after being preserved in poo for 230 million years.

Researchers have found the earliest known strain of the plague-causing Yersinia pestis bacteria, through genetic analysis of teeth and bone from a hunter-gatherer who was buried in present-day Latvia 5,000 years ago.

By studying the logs of computer malfunctions caused by high-energy particles striking their circuitry, ESA scientists have used "housekeeping" data from the Rosetta and Mars Express deep-space probes to shed new light on cosmic rays in the solar system.

Despite an abrupt and unscheduled ending to its six-seater test program, hydrogen aviation pioneer ZeroAvia is ramping up development of the largest fuel cell-powered aircraft to date – a pair of 19-seaters – and is preparing for something much bigger.

While electric vehicles are greener than their fuel-burning counterparts, their battery packs still aren't as recyclable as they could be. A new process could help, by more efficiently extracting reusable materials from old lithium-ion batteries.

Velotton introduced the fairly lightweight Vekkit conversion kit last year for those who can't afford the often high price tags of dedicated ebikes, and now version two has been announced – adding a GPS+LTE module and new battery options.

Researchers believe they have found evidence indicating excess production of a neurotransmitter in the liver could be a causal factor in the onset of insulin resistance. The discovery points to preventative treatments for type 2 diabetes.

By taking lessons from the world of supercar design and leveraging its own expertise built up over 13 years of production, Australian outfit Evolve has just wheeled out its most advanced electric skateboard to date.

Few things punish bicycle wheels harder than world championship-level downhill mountain bike racing, so France's Nawa Technologies has signed up with a top-level downhill team to prove the strength of its nanotube-reinforced carbon fiber.

A research group in the US has taken a significant step forward with a design for a long-lasting lithium metal battery with high capacity, which remained functional for a record-breaking number of charging cycles.
