22 Sept 2021

Engineers have led research that discovers a way to generate renewable biofuel additives, using radiation that could be derived from nuclear waste. The renewable proportion of petrol is set to increase to 20 percent over the coming years, meaning the discovery of a new production pathway for these additives could help in the fight to cut carbon dioxide emissions and tackle climate change.

3.    Gigantic Cavity in Space Sheds New Light on How Stars Form

Astronomers analyzing 3D maps of the shapes and sizes of nearby molecular clouds have discovered a gigantic cavity in space. The sphere-shaped void spans about 150 parsecs — nearly 500 light-years — and is located on the sky among the constellations Perseus and Taurus.

4.    Reactor Makes Martian Fuel

22 Sept 2021

Researchers designed a new flying microchip by studying the aerodynamics of wind-dispersed seeds. The team used mechanisms similar to those of pop-up books to manufacture the devices. The resulting technology is packed with ultra-miniaturized sensors and wireless communication capabilities.

6.    A New Solid-State Battery Surprises the Researchers Who Created It

23 Sept 2021

Engineers created a new type of battery that weaves two promising battery sub-fields into a single battery. The battery uses both a solid-state electrolyte and an all-silicon anode, making it a silicon all-solid-state battery. The initial rounds of tests show that the new battery is safe, long-lasting, and energy-dense. It holds promise for a wide range of applications from grid storage to electric vehicles.
