Humanlike 'Teeth' Have Been Grown in Mini Pigs

3 months 1 week ago
Scientists have grown tooth-like structures using a combination of pig and human cells, marking a step toward potential alternatives to dental implants, researchers at Tufts University School of Dental Medicine reported. The team, led by Pamela Yelick and Weibo Zhang, cultivated the structures by seeding cells into pig tooth scaffolds and implanting them in mini pigs' jaws. After two months, the bioengineered teeth developed hard tissue layers similar to natural teeth, including dentin and cementum. While not yet fully formed teeth, the structures could eventually lead to living replacements for lost teeth, addressing limitations of current titanium implants.

DeepSeek's AI App Will 'Highly Likely' Get Banned in the US, Jefferies Says

3 months 1 week ago
DeepSeek's AI app will highly likely face a US consumer ban after topping download charts on Apple's App Store and Google Play, according to analysts at US investment bank Jefferies. The US federal government, Navy and Texas have already banned the app, and analysts expect broader restrictions using legislation similar to that targeting TikTok. While consumer access may be blocked, US developers could still be allowed to self-host DeepSeek's model to eliminate security risks, the analysts added. Even if completely banned, DeepSeek's impact on pushing down AI costs will persist as US companies work to replicate its technology, Jefferies said in a report this week reviewed by Slashdot. The app's pricing advantage remains significant, with OpenAI's latest o3-mini model still costing 100% more than DeepSeek's R1 despite being 63% cheaper than o1-mini. The potential ban comes amid broader US-China tech tensions. While restrictions on H20 chips appear unlikely given their limited training capabilities, analysts expect the Biden administration's AI diffusion policies to remain largely intact under Trump, with some quota increases possible for overseas markets based on their AI activity levels.
