aarondubrow shares a report from the Texas Advanced Computing Center: A new study in the Bulletin of the Seismological Society of America presents results from a new earthquake simulator, RSQSim, that simulates hundreds of thousands of years of seismic history in California. Coupled with another code, CyberShake, the framework can calculate the amount of shaking that would occur for each quake. [The framework makes use of two of the most powerful supercomputers on the planet: Frontera, at the Texas Advanced Computing Center, and Summit, at Oak Ridge National Laboratory].

The new approach improves [seismologists’] ability to pinpoint how big an earthquake might occur at a given location, allowing building code developers, architects, and structural engineers to design more resilient buildings that can survive earthquakes at a specific site.

An anonymous reader quotes a report from Ars Technica: Bad news, land-speed record fans: the project to set a new 1,000mph (1,609km/h) speed record is yet again in serious doubt. On Monday morning, the Bloodhound Land Speed Record Project revealed that it’s looking for a new owner in order to try and break the existing record. Whoever steps in will need pretty deep pockets, too — almost $11 million, in fact. Trying to set a new land-speed record is probably one of the harder activities one can engage in. You need to design and build a vehicle capable of going faster than 763mph (1,228km/h), twice within an hour. You need to find somewhere flat enough to run the car, presumably away from neighbors who might get annoyed by the window-shattering sonic booms. And while all that sounds like a serious challenge, perhaps the biggest problem is finding the money to make it all happen.

2019 was a good year for Bloodhound. It found a new owner who saved it from life as a museum curio, and it even arrived in South Africa for the start of high-speed testing. Although it was only equipped with its Rolls Royce EJ200 jet engine, Bloodhound still reached 628mph (1,010kmh) that year. But going faster will require integrating Bloodhound’s other propulsion source, a monopropellant rocket made by Nammo (a Norwegian aerospace and defense company). And the cost to do that and then conduct the test program to set a new record will require about $11 million, according to current owner Ian Warhurst. In a statement, he said: “When I committed to take the car high-speed testing in 2019, I allocated enough funding to achieve this goal on the basis that alternative funding would then allow us to continue to the record attempts. Along with many other things, the global pandemic wrecked this opportunity in 2020 which has left the project unfunded and delayed by a further 12 months. At this stage, in absence of further, immediate, funding, the only options remaining are to close down the program or put the project up for sale to allow me to pass on the baton and allow the team to continue the project.”

Moderna’s Covid vaccine appears to work against new, more infectious variants of the pandemic virus found in the UK and South Africa, say scientists from the US pharmaceutical company. The BBC reports: Early laboratory tests suggest antibodies triggered by the vaccine can recognize and fight the new variants. More studies are needed to confirm this is true for people who have been vaccinated. Current vaccines were designed around earlier variants, but scientists believe they should still work against the new ones, although perhaps not quite as well. There are already some early results that suggest the Pfizer vaccine protects against the new UK variant.

For the Moderna study, researchers looked at blood samples taken from eight people who had received the recommended two doses of the Moderna vaccine. The findings are yet to be peer reviewed, but suggest immunity from the vaccine recognizes the new variants. Neutralizing antibodies, made by the body’s immune system, stop the virus from entering cells. Blood samples exposed to the new variants appeared to have sufficient antibodies to achieve this neutralizing effect, although it was not as strong for the South Africa variant as for the UK one. Moderna says this could mean that protection against the South Africa variant might disappear more quickly. Moderna says it’s investigating whether a redesigned vaccine would be more effective against the new variants. It’s also testing whether giving a third booster shot might be beneficial.

A Vancouver seaplane company says its retro-fitted all electric airplane is set to take to the skies for more test flights this year, as it pushes forward with its plans to make commercial air travel cheaper and greener. CBC.ca reports: “There’s no wavering in our confidence and determination and interest in getting this done,” said Harbour Air CEO Greg McDougall. Founded by McDougall in 1982, Harbour Air uses small propeller planes to fly commercial flights between the Lower Mainland, Seattle, Vancouver Island, the Gulf Islands and Whistler.

In the last few years it has turned its attention to becoming a leader in green urban mobility, which would do away with the need to burn fossil fuels for air travel. In December 2019, McDougall flew one of Harbour Air’s planes, a more than 60-year-old DHC-2 de Havilland Beaver float plane, which had been outfitted with a Seattle-based company’s electric propulsion system, for three minutes over Richmond B.C.

Harbour Air joined with Seattle-based company MagniX in early 2019 to design the e-plane’s engine, which was powered by NASA-approved lithium-ion batteries that were also used on the International Space Station. At the time, based on the success of that inaugural flight, McDougall had hoped to be using the plane to fly passengers on its routes, such as between downtown Vancouver and downtown Victoria, by the end of this year. Now, that timeline has been pushed back at least one year due to the pandemic.
