On August 8 2021, an experiment at Lawrence Livermore National Laboratory’s (LLNL’s) National Ignition Facility (NIF) made a significant step toward ignition, achieving a yield of more than 1.3 megajoules (MJ). This advancement puts researchers at the threshold of fusion ignition, an important goal of the NIF, and opens access to a new experimental regime.

The experiment was enabled by focusing laser light from NIF — the size of three football fields — onto a target the size of a BB that produces a hot-spot the diameter of a human hair, generating more than 10 quadrillion watts of fusion power for 100 trillionths of a second.

“These extraordinary results from NIF advance the science that NNSA depends on to modernize our nuclear weapons and production as well as open new avenues of research,” said Jill Hruby, DOE under secretary for Nuclear Security and NNSA administrator.

A new ransomware gang known as LockFile encrypts Windows domains after hacking into Microsoft Exchange servers using the recently disclosed ProxyShell vulnerabilities.

ProxyShell is the name of an attack consisting of three chained Microsoft Exchange vulnerabilities that result in unauthenticated, remote code execution.

The three vulnerabilities were discovered by Devcore Principal Security Researcher Orange Tsai, who chained them together to take over a Microsoft Exchange server in April’s Pwn2Own2021hacking contest.

The Nevera packs four electric motors that send 1,914 horsepower (1,408 kilowatts) to all four wheels. The car is also wearing Michelin Pilot Sport 4S tires while tipping the scales at 4,733 pounds (2,146 kilograms). It has an MSRP of $2.4 million. The Tesla Model S is far less powerful and cheaper, but it still impresses with its 1,020 hp (760 kW) output, thanks to its three-motor setup. It’s heavier than the Rimac at 4,833 lbs (2,192 kg), though it’s much cheaper at $124,000. Power routes to all four Michelin Pilot Sport 4S tires.

Watch as the Tesla Model S Plaid faces off against the Rimac Nevera hypercar in a series of high-powered EV drag races.

Web infrastructure and website security company Cloudflare on Thursday disclosed that it mitigated the largest ever volumetric distributed denial of service (DDoS) attack recorded to date.

The attack, launched via a Mirai botnet, is said to have targeted an unnamed customer in the financial industry last month. “Within seconds, the botnet bombarded the Cloudflare edge with over 330 million attack requests,” the company noted, at one point reaching a record high of 17.2 million requests-per-second (rps), making it three times bigger than previously reported HTTP DDoS attacks.

“Stay safe friends,” astronaut Megan McArthur says.

As parts of the U.S. northeast brace for Hurricane Henri to make landfall in New York today (Aug. 22), astronauts and satellites are tracking the historic storm from space.

Henri, which reached category 1 hurricane status on Saturday, is forecast to make landfall on Long Island, New York by midday today, dropping torrents of rain on Connecticut and Rhode Island, according to the National Hurricane Center’s morning update. Astronauts on the International Space Station spotted Henri from orbit on Saturday.

The Japan Aerospace Exploration Agency (JAXA) has announced that it has successfully demonstrated the operation of a “rotating detonation engine” for the first time in space. The novelty of the technologies in question is that such systems obtain a large amount of thrust by using much less fuel compared to conventional rocket engines, which is quite advantageous for space exploration.

On July 27 the Japanese agency launched a pair of futuristic propulsion systems into space to carry out the first tests. They were launched from the Uchinoura Space Center aboard the S-520–31, a single-stage rocket capable of lofting a 220 lbs (100 kg) payload well above 186 miles (300 km). After recovering the rocket from the ocean, the JAXA team of engineers analyzed the data and confirmed the success of the mission, which put the new system at an estimated altitude of (146 miles) 234.9 km.

The rotating detonation engine uses a series of controlled explosions that travel around an annular channel in a continuous loop. This process generates a large amount of super-efficient thrust coming from a much smaller engine using significantly less fuel – which also means sending less weight on a space launch. According to JAXA, it has the potential to be a game-changer for deep space exploration.
