Four decades of supersonic-combustion ramjet propulsion research culminated in a successful flight of the X-43A hypersonic technology demonstrator in March 2004, the first time a scramjet-powered aircraft had flown freely. After being launched by Dryden’s venerable B-52B mothership off the coast of Southern California, a modified first-stage Pegasus booster rocketed the X-43A to 95,000 feet before the X-43A separated and flew under its own scramjet power at an airspeed of Mach 6.8, or about 5,000 mph, for about 11 seconds. On Nov. 16, another identical scramjet-powered X-43A did it again, this time reaching hypersonic speeds above Mach 9.6, or about 6,800 mph, in the final flight of the X-43A project. Both flights set world airspeed records for an aircraft powered by an air-breathing engine, and proved that scramjet propulsion is a viable technology for powering future space-access vehicles and hypersonic aircraft.

SpaceX gets regulatory approval to offer Starlink Internet in Canada
Posted by Raphael Ramos in categories: internet, satellites
SpaceX has finally received approval from Canadian authorities to offer its Starlink satellite Internet service in the country, a decision that comes amid a recent expansion of the beta program in the US. With this approval in place, SpaceX will be able to offer rural Canadians access to high-speed broadband, something that will slowly expand into other countries, as well.

Scientists used a human gene to grow bigger monkey brains

Video. Hopefully they are satisfied with this. Otherwise, I think we would end up with planet of the apes…
At least they know which gene helps make brains bigger.

‘Electronic skin’ promises cheap and recyclable alternative to wearable devices
Posted by Saúl Morales Rodriguéz in categories: electronics, wearables
Researchers at the University of Colorado Boulder are developing a wearable electronic device that’s “really wearable”—a stretchy and fully-recyclable circuit board that’s inspired by, and sticks onto, human skin.
The team, led by Jianliang Xiao and Wei Zhang, describes its new “electronic skin” in a paper published today in the journal Science Advances. The device can heal itself, much like real skin. It also reliably performs a range of sensory tasks, from measuring the body temperature of users to tracking their daily step counts.
And it’s reconfigurable, meaning that the device can be shaped to fit anywhere on your body.

China sends ‘world’s first 6G’ test satellite into orbit
Posted by Derick Lee in categories: internet, satellites
The telecoms industry is still several years away from agreeing on 6G’s specifications, so it is not yet certain the tech being trialled will make it into the final standard.
It involves use of high-frequency terahertz waves to achieve data-transmission speeds many times faster than 5G is likely to be capable of.
The satellite is meant to trial new technology expected to be many times faster than 5G.

China successfully sends world’s first 6G satellite into orbit to test technology
Posted by Muhammad Furqan in categories: internet, satellites
#China is in the rush to shape the future.
The rollout of 5G networks is nowhere near complete, but China is already looking ahead to what comes next. The Asian power this week successfully launched the world’s first 6G satellite into space to test the technology.
The experimental satellite containing sixth-generation telecommunications technology was launched into Earth’s orbit from the Taiyuan Satellite Launch Center in China’s northern Shanxi Province on Friday.

Researchers claim their graphene “SuperBattery” achieves a 15-second charging time
Posted by Quinn Sena in categories: energy, materials
Skeleton Technologies and the Karlsruhe Institute of Technology (KIT) say they have developed a graphene-based battery with a 15-second charging time, as well as charging cycles counted in the hundreds of thousands.
The so-called SuperBattery’s key component is Skeleton’s patented Curved Graphene carbon material, which enables the high power and long lifetime of ultracapacitors to be applied in a graphene battery.
“The SuperBattery is a game-changer for the automotive industry. Together with Li-ion batteries, they have it all: high energy and power density, long lifetime and 15-second charging time,” said Skeleton Technologies CEO Taavi Madiberk.
