A group of researchers from the US and Russia have found a way to create a new type of ultra-light aluminium that’s even lighter than water. The team is made up of Utah State University chemist Alexander Boldyrev and four more from Southern Federal University in Rostov-on Don, Russia.
“They started with a known crystal lattice, in this case, a diamond, and substituted every carbon atom with an aluminium tetrahedron,” Boldyrev says of their innovative approach.
“According to the calculations, forging aluminium in this form makes it more lightweight. The resulting metal had a density of only 0.61 gram per cubic centimetre, instead of aluminium’s usual density of 2.7 grams per cubic centimetre,” Reports India Times.
This new form of ultra-light metal could revolutionise every industry from aircraft manufacturing to everyday household appliances.

Part of an aeroplane's wing broke off and landed on a car driving along a road in central Osaka, Japan, damaging the car's roof and smashing a rear window. Two women were in the car, but no one was harmed.
“The KLM flight had taken off from Kansai International Airport in Osaka on Saturday morning when the chunk weighing 4.3kgs, fell off,” Reports Stuff.nz.
The Boeing 777 landed safely at Amsterdam's Schiphol airport later on Saturday, and was carrying over 300 passengers and crew.

The world’s largest aircraft with a wingspan of 118 across - larger than a professional football field- has completed its first initial tests. The aircraft, developed by the spaceflight company Stratolaunch, which is led by Microsoft co-founder Paul Allen, is designed as a launch platform for sending rockets into low-earth orbit.
"In these initial tests, each of the six engines operated as expected," Stratolauch announced.

Viewers can visit different parts of former RAF Avro Vulcan B2, from navigating the cockpit and the bomb bay, to walking along its wings, all from the comfort of their own home.
Enthusiasts can navigate the 360 degree view via a PC, or use virtual reality goggles like Google Cardboard and Samsung VR, for a more immersive experience.

This wind tunnel at the Royal Aircraft Establishment in Farnborough, Hampshire, was built in 1935 to study how wind affected objects, and played a crucial role in developing World War II aeroplanes. One aeroplane that was later tested here was the Hawker Hurricane which became the main force for victory in the Battle of Britain.
The wind tunnel was once a military secret, but it now sits abandoned save for open days and guided tours run by the Farnborough Air Sciences Trust.
