In a list of walls that you’d want to stay strong, those in a nuclear reactor would be near the top. Now, researchers have found that the walls in a decommissioned power plant in Japan have not only kept their strength but have actually gotten stronger with use, thanks to a rare mineral also found in ancient Roman concrete.
Viruses firmly hold the world’s attention at the moment, but we shouldn’t ignore the rising health threat that bacteria pose, too. The crafty critters are fast evolving resistance to antibiotics, meaning our best drugs could soon stop working entirely. Now researchers in Australia have found a way to bypass drug resistance in these so-called superbugs – by distracting them with predatory viruses.
Boeing has begun production of the “real-as-it-gets” ground-based training system (GBTS) flight simulator of the US Air Force’s new T-7A Red Hawk training jet. For immersive realism, each unit features dynamic motion seats and the Boeing Constant Resolution Visual System’s 8K native projectors, which have 16 times the resolution of a 1080p high-definition video screen.
A student-built CubeSat from the University of Michigan will investigate whether small satellites can be maintained in low Earth orbit without thrusters or propellant. Scheduled to launch from the Mojave Air and Space Port on Virgin Orbit’s Launch Demo 2 on January 10, 2020, the Miniature Tether Electrodynamics Experiment-1 (MiTEE-1) will test the concept of using the Earth’s magnetic field to generate thrust.
It’s rare that gravel gets scientists so excited, but these are no ordinary rocks. They’re the samples returned to Earth by Hayabusa2 after its 5.24-billion-km round trip to asteroid Ryugu, and this is our first glimpse at them after the spacecraft landed in the Australian Outback on December 6 and its sample container was transported to Japan.
SpaceX has been making controlled landings of its Falcon 9 boosters to allow them to be reused for a number of years now. Such landings involve the rockets touching down, be it on a boat or a launch pad, using legs built into the rocket. But SpaceX CEO and founder Elon Musk has revealed different plans for the Falcon 9’s bigger sibling, the Super Heavy, announcing the intention to have the launch tower arm catch the booster.
