But they don’t necessarily resemble the ones we know from classic films.

If you’re looking for a taste of what the Air Force’s first new F-15 fighter jet in nearly 20 years might look like, look no further than the first flight of the F-15QA.

Developed for the Qatar Emiri Air Force and billed as “the most advanced version of the jet ever manufactured,” Boeing announced on Tuesday that it had successfully completed the first flight of its F-15QA variant at Lambert International Airport in St. Louis, Missouri.

The parasite Toxoplasma gondii has been found near Oahu, Hawaii public lands for the first time.

China might be secretly conducting nuclear tests with very low explosive power despite Beijing’s assertions that it is strictly adhering to an international accord banning all nuclear tests, according to a new arms-control report to be made public by the State Department.

The coming report doesn’t present proof that China is violating its promise to uphold the agreement, but it cites an array of activities that “raise concerns” that Beijing might not be complying with the “zero-yield” nuclear-weapons testing ban.

Most quantum computers being developed around the world will only work at fractions of a degree above absolute zero. That requires multi-million-dollar refrigeration and as soon as you plug them into conventional electronic circuits they’ll instantly overheat.

But now researchers led by Professor Andrew Dzurak at UNSW Sydney have addressed this problem.

“Our new results open a path from experimental devices to affordable quantum computers for real world business and government applications,” says Professor Dzurak.

The widespread perception that it was once official British policy to let the novel coronavirus spread until the population reached herd immunity is false; the government was just overly optimistic about how easy flattening the curve would be. But the idea has gained so much traction in some circles, fueled by speculation that we might already be much closer to it than we think, that it’s worth understanding why it’s not a viable policy according to the evidence to date.

As the world fights against the COVID-19 pandemic, nuclear weapons have taken a backseat in most people’s minds. But for Global Strike Command (AFGSC)—the Air Force unit in control of two of the three legs of America’s nuclear triad—their mission remains top priority.

And it’s an unforgiving business. Nuclear deterrence requires extreme levels of readiness among pilots, maintenance crews, and security teams. Adversaries that don’t think the U.S. can respond with conventional bombing strikes or nukes could be emboldened to act aggressively.

Experts explained to Newsweek why this doesn’t jeopardize efforts to create a vaccine to prevent COVID-19.

The mining industry is focused on continuing production through the COVID-19 pandemic, writes Margaret Gleeson, despite workers’ and local communities’ concerns.
