Former cryptocurrency poster boy Sam Bankman-Fried is trying to get another chance in court. He has filed a request that for a new trial on claims that new witness testimony could alter the case made against him by prosecutors, according to Bloomberg. His odds for getting the re-trial, where he'd be representing himself, seem pretty slim. This is a separate motion from a formal appeal of his previous conviction.Bankman-Fried is one of many cryptocurrency leaders who have since been prosecuted for fraud. After being jailed for witness tampering, he was found guilty of seven charges of fraud and conspiracy in 2023. Bankman-Fried was sentenced to 25 years in prison for his actions as CEO and co-founder of crypto exchange FTX.

Hubble may no longer be the gold standard, but it can still capture some impressive images. The telescope's latest snapshot is our clearest view yet of the Egg Nebula. Roughly 3,000 light-years away from Earth, the nebula's name is derived from its dense layer of gas and dust cloaking a central star.The new image shows the nebula's four beams of starlight (from that central star) escaping from its gas-and-dust "shell." On either side of the disc-like cloud are fast-moving outflows of hot molecular hydrogen. The orange highlights in this image indicate the glow of infrared light.As the beams of starlight stretch out from the center, they illuminate concentric rings of gas. The gass ripple-like pattern suggests it was created by successive bursts from the star, with a little more ejecting every few hundred years.Hubble image of the Egg Nebula. A disc of gas and dust surrounded by beams of light and concentric rings of dust.SA / Hubble & NASA, B. Balick (University of Washington)The Egg Nebula, found in the constellation Cygnus, was first discovered in 1975. Nebulae in this preplanetary phase are rare finds. Since the stage only lasts a few thousand years (and because they're often faint), they're relatively difficult for astronomers to spot. By comparing this new image with previous Hubble snapshots of the Egg Nebula, astronomers can learn more about it and shed more light on its processes. But for the rest of us, it makes for some pretty sweet eye candy, right?This article originally appeared on Engadget at https://www.engadget.com/science/space/hubble-showcases-the-egg-nebula-in-all-its-dying-star-glory-174239769.html?src=rss

Get ye to Windows Update, because there's a good chance you've got new Secure Boot certificates to install. Microsoft just announced that it will be refreshing those certificates, which were originally introduced when Secure Boot debuted in 2011, as a security precaution. Secure Boot was a way for Microsoft to protect systems from running unsigned and potentially malicious code before Windows launched. It went on to be an installation requirement for Windows 11, as well as anti-cheat software used in Valorant, Call of Duty: Black Ops 6/7 and Battlefield 6. Without the new Secure Boot certificates, Microsoft says your system will still function normally, but it will enter "a degraded security state that limits its ability to receive future boot-level protections." Basically, you won't be protected from malware and viruses targeting vulnerabilities in older versions of Windows. As expected, Microsoft also notes that unsupported versions of Windows won't be receiving the new Secure Boot certificates. They're only coming to Windows 11 systems, as well as Windows 10 PCs subscribed to Microsoft's Extended Security Updates.Microsoft says many users will be able to pick up the updated Secure Boot certificates by visiting Windows Update, but a few may need additional firmware updates from their system (or motherboards) OEM. Youll also be able to track the status of your security certificates in the Windows Security app in the coming months."As cryptographic security evolves, certificates and keys must be periodically refreshed to maintain strong protection," Nuno Costa, Partner Director of Windows Servicing and Delivery, wrote in a blog post today. "Retiring old certificates and introducing new ones is a standard industry practice that helps prevent aging credentials from becoming a weak point and keeps platforms aligned with modern security expectations."Costa says Microsoft has been working with OEMs like Dell and HP to ensure a smooth transition to the new Secure Boot certificates. Many new systems built in 2024 already have the updated certs, while "almost all" devices shipped last year have them as well. Microsoft has also been alerting IT customers to this transition since last year.This article originally appeared on Engadget at https://www.engadget.com/computing/microsoft-will-start-refreshing-secure-boot-certificates-in-march-for-windows-11-and-windows-10-esu-users-170000777.html?src=rss
