Virgin Galactic’s manned spaceplane has hit another milestone, breaking Mach 2 as it roared into the mesosphere. With test pilots Dave Mackay and Mike “Sooch” Masucci at the controls, VSS Unity was released from the mothership VMS Eve at an altitude of 46,500 ft (14,200 m) before firing its hybrid rocket engine for 42 seconds to power it to 170,800 ft (32.3 mi, 52 km) and a speed of Mach 2.47 (1,832 mph, 2,948 km/h).
The bacteria that call your gut home can have a tremendous impact on your overall health, but exactly how the bugs do so is a web that’s still being untangled. To investigate, researchers at Harvard Medical School have deleted a single gene from one gut bacteria species and found that it alters the metabolism of the host, reducing their weight gain.
After releasing some poorly-lit preview pictures with consecutive GT-R50 announcements, Nissan revealed the car in full at the weekend’s Goodwood Festival of Speed. As expected, the striking anniversary-edition GT-R developed in collaboration with Italdesign makes quite a memorable impression when swimming in the full light of day.
The announcement of the United Kingdom’s new Tempest fighter project marks yet another new fighter program set to delivery in the 2030s. In addition to Tempest, a new Japanese fighter, a Franco-German project, and whatever China and Russia are surely working on, the United States has not one but two fighter jets.
In case you weren’t already sure that diamonds aren’t as unique or valuable as advertisers want us to believe, the next blow to Big Diamond might have just arrived. Using sound waves, geologists have discovered a gigantic stash of the so-called precious stones deep in the Earth’s interior, possibly to the tune of a quadrillion tons.
They’ve been around for the past 300 million years, outlasting the dinosaurs and teaming up with evolution to outsmart our attempts to get rid of them. Now, Japanese researchers at Hokkaido University have revealed yet another reason why we have been unable to put a dent in their populations: female solidarity.
General Atomics Aeronautical Systems Inc’s (GA-ASI) SkyGuardian drone set out today on its historic transatlantic flight. At 12:48 pm CDT, the MQ-9B Medium-altitude, Long-endurance (MALE) Remotely Piloted Aircraft (RPA) took off from the company’s Flight Test and Training Center in Grand Forks, North Dakota and is on its way to RAF Fairford in Gloucestershire, England.
The UK’s Archie O’Brien had a dream of zipping below the waters off Iceland or swimming with dolphins off the coast of Bora Bora. He looked at contraptions that would pull him along underwater at speed – something like the AquaJet H2 or Scubalec, for example – but everything already available proved beyond his reach. So he decided to design and build the Cuda underwater jetpack, which will be going into production early next year.
An impressive Australian trial that released millions of sterilized male mosquitoes in Queensland has resulted in a more than 80 percent drop in the population of this disease-spreading insect. The international collaboration involved scientists from Australia’s James Cook University (JCU) and the CSIRO, working with a new mosquito-rearing technology developed by Verily, an independent subsidiary of Google’s parent company Alphabet.
