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

Eldson Chagara 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 […]

Analysis confirms that climate change is making wildfires worse

Climate change has already increased the risk of wildfire globally, according to a new review of research that suggests the weather conditions that led to the Australian wildfires will become more common in future. By Donna Lu Read more: In light of the ongoing wildfire crisis in Australia, Richard Betts at the UK Met Office in […]

Australia’s fire-driven storms are pumping smoke into the stratosphere

Thunderstorms generated by the Australian bushfires are very likely to have pumped as much smoke into the stratosphere as a volcanic eruption. By Adam Vaughan Read more: Blazes across the country in the past few weeks have been so intense they have generated their own weather. They create rising air mixed with ash and smoke that results […]

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. Read more: By Layal Liverpool The plastic bunny was developed by the teams of Robert Grass at […]

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: 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: 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: “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: 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 […]

Ozone hole recovery will probably be delayed by banned gas from China

The recovery of the ozone hole over Antarctica is likely to be delayed by the illegal production of an ozone-destroying gas in China, according to the first assessment of the banned chemical’s impact. Read more: In the worst case, the recovery will be delayed by around 18 years if production of trichlorofluoromethane (CFC-11), used to […]
