The BMJ asked Facebook co-founder Mark Zuckerberg to remove a warning that discourages Facebook users from sharing an article about flaws in Pfizer’s COVID vaccine trial, saying the platform’s “incompetent” fact checkers are unfaily labeling stories as false. In an open letter Friday, The BMJ editors explained how some readers are unable to post its Nov. 2 article on Facebook. Other readers have received pop-up warnings that if they choose to share “false information,” their posts may rank lower in Facebook’s news feed.

“We find the ‘fact check’ performed by Lead Stories to be inaccurate, incompetent and irresponsible,” wrote The BMJ editors Fiona Godlee and Kamran Abbasi. “It fails to provide any assertions of fact that The BMJ article got wrong.” The BMJ article last month documented a host of poor practices that may have hurt data integrity and patient safety in the Phase 3 trial for Pfizer’s COVID vaccine. A whistleblower had supplied The BMJ with internal company documents, photos, audio recordings and e-mails from a contract research company overseeing some trial sites. The U.S. Food and Drug Administration declined to inspect the affected sites despite receiving a direct complaint in 2020, The BMJ said. Pfizer’s vaccine, called Comirnaty, received approval in August 2021. “There is also a wider concern that we wish to raise,” The BMJ wrote in its letter to Zuckerberg. “We are aware that The BMJ is not the only high quality information provider to have been affected by the incompetence of Meta’s fact checking regime.”

Facebook isn’t Lead Stories’ only client. The company also works for Google, ByteDance (TikTok’s owner) and the Poynter Institute for Media Studies. The fact checker’s stated mission is to “hunt for trending stories, images, videos and posts that contain false information in order to fact check them as quickly as possible.” The BMJ urged Zuckerberg to act swiftly, “specifically to correct the error relating to The BMJ’s article and to review the processes that led to the error; and generally to reconsider your investment in and approach to fact checking overall.”

Twitter executives deceived federal regulators and the company’s own board of directors about “extreme, egregious deficiencies” in its defenses against hackers, as well as its meager efforts to fight spam, according to an explosive whistleblower complaint from its former security chief.The complaint from former head of security Peiter Zatko, a widely admired hacker known as “Mudge,” depicts Twitter as a chaotic and rudderless company beset by infighting, unable to properly protect its 238 million daily users including government agencies, heads of state and other influential public figures.Among the most serious accusations in the complaint, a copy of which was obtained by The Washington Post, is that Twitter violated the terms of an 11-year-old settlement with the Federal Trade Commission by falsely claiming that it had a solid security plan. Zatko’s complaint alleges he had warned colleagues that half the company’s servers were running out-of-date and vulnerable software and that executives withheld dire facts about the number of breaches and lack of protection for user data, instead presenting directors with rosy charts measuring unimportant changes.The complaint — filed last month with the Securities and Exchange Commission and the Department of Justice, as well as the FTC — says thousands of employees still had wide-ranging and poorly tracked internal access to core company software, a situation that for years had led to embarrassing hacks, including the commandeering of accounts held by such high-profile users as Elon Musk and former presidents Barack Obama and Donald Trump.

In the middle of the night, invisible to anyone but special telescopes in two Chinese observatories, satellite Micius sends particles of light to Earth to establish the world’s most secure communication link. Named after the ancient Chinese philosopher also known as Mozi, Micius is the world’s first quantum communications satellite and has, for several years, been at the forefront of quantum encryption. Scientists have now reported using this technology to reach a major milestone: long-range secure communication you could trust even without trusting the satellite it runs through. Launched in 2016, Micius has already produced a number of breakthroughs under its operating team led by Pan Jian-Wei, China’s “Father of Quantum”. The satellite serves as the source of pairs of entangled photons, twinned light particles whose properties remain intertwined no matter how far apart they are. If you manipulate one of the photons, the other will be similarly affected at the very same moment.

It is this property that lies in the heart of the most secure forms of quantum cryptography, the entanglement-based quantum key distribution. If you use one of the entangled particles to create a key for encoding messages, only the person with the other particle can decode them.

Secure long-distance links such as this one will be the foundation of the quantum internet, the future global network with added security powered by laws of quantum mechanics, unmatched by classical cryptographic methods. The launch of Micius and the records set by the scientists and engineers building quantum communication systems with its help have been compared to the effect Sputnik had on the space race in the 20th century. In a similar way, the quantum race has political and military implications that are hard to ignore.
