Huawei Still Faces U.S. Questions About Its Ties To Chinese Government

Náhled

Watch Video The U.S. is blacklisting Chinese tech firms like Huawei over national security concerns — but those concerns are rooted in what we don't know about the company rather than what we do know.As of now, there's no public smoking gun tying Huawei to any Chinese attempts to compromise U.S. national security. Independent  security reviews  have uncovered flaws and vulnerabilities in Huawei's equipment, but haven't found evidence of malicious activity on the company's part. But that doesn't mean Huawei is in the clear: The U.S. is still worried China might compel the company to provide it a backdoor into U.S. networks at some point in the future.Huawei is a private company, nominally separate from the Chinese government. But its exact relationship to the state is still unclear. A 2012  congressional investigation  found the company "cannot be trusted to be free of foreign state influence." The company's U.S. executives recently promised more transparency about its structure in the future.The question of whether to trust Huawei matters because the company is on the forefront of the race to deploy 5G networks worldwide. Only Australia, New Zealand and Japan have joined the U.S. in blacklisting Huawei, while some other countries remain undecided.Even the U.S. ban on Huawei has seemed uncertain at times. President Trump has talked about relaxing U.S. actions against Chinese tech firms in exchange for trade concessions. Číst dále >>> Přeložit do en

Social Media Giants Detail Disinformation Plans At VA Hearing

Náhled

Watch Video Social media's persistent disinformation problem has put one group at particular risk: U.S. veterans. Lawmakers have asked Facebook and Twitter how they plan to address groups that use the likeness of veterans as leverage to spread propaganda and scams.The hearing at the Committee on Veterans’ Affairs comes after months of reports that American service members, veterans and their relatives are at the center of a foreign disinformation scheme. For example, one investigation found that foreign adversaries routinely create social media accounts that look like they belong to American Veterans, then use them to spread propaganda in Facebook groups, or run romance scams.So far, platforms have been slow to crack down. A New York Times report from July of 2019 explained Facebook was trying to filter out fake profiles, using images from veterans who were victims of identity theft. Months later, the fake accounts were still up. Social media reps acknowledged they needed to do more, and told the committee that policy changes would be imminent."We are testing new detection capabilities to look for certain techniques these scammers use to target individuals such as veterans. These capabilities help us more quickly detect and remove scammer accounts, often before people even see them."Twitter, like Facebook, is looking at the bigger picture — how new measures that protect veterans could help protect the whole userbase. "It’s resulted in approximately 97 million challenges from Twitter just for the first half of this year alone. We continue to invest and look at the behavior, look at the signals behind how these accounts are behaving and potentially targeting people to include veterans, but we take a much more holistic approach so we’re not just siloing certain communities and we can apply lessons learned across the board."

No deliveries: How cells decide when to accept extracellular packages

Náhled

Endocytosis, a fundamental process that cells use to take in macromolecules, functions a lot like an airlock on a spaceship -- but squishier, says a researcher. Researchers have studied how cells initiate and perform endocytosis since the 1960s, but in a new article they finally describes how cells shut down this important cellular machinery. And their findings are not without controversy. Číst dále >>> Přeložit do en
