Rice, the world’s most consumed grain, will become increasingly toxic as the atmosphere heats and as carbon dioxide emissions rise, potentially putting billions of people at risk of cancers and other diseases, according to new research published Wednesday in The Lancet.

Eaten every day by billions of people and grown across the globe, rice is arguably the planet’s most important staple crop, with half the world’s population relying on it for the majority of its food needs, especially in developing countries.

But the way rice is grown—mostly submerged in paddies—and its highly porous texture mean it can absorb unusually high levels of arsenic, a potent carcinogenic toxin that is especially dangerous for babies.

On Wednesday, OpenAI announced the release of two new models—o3 and o4-mini—that combine simulated reasoning capabilities with access to functions like web browsing and coding. These models mark the first time OpenAI's reasoning-focused models can use every ChatGPT tool simultaneously, including visual analysis and image generation.

OpenAI announced o3 in December, and until now, only less capable derivative models named "o3-mini" and "03-mini-high" have been available. However, the new models replace their predecessors—o1 and o3-mini.

OpenAI is rolling out access today for ChatGPT Plus, Pro, and Team users, with Enterprise and Edu customers gaining access next week. Free users can try o4-mini by selecting the "Think" option before submitting queries. OpenAI CEO Sam Altman tweeted that "we expect to release o3-pro to the pro tier in a few weeks."

Should the city of Houston, which proudly bills itself as "Space City," have a prized Space Shuttle orbiter on public display?

More than a decade ago, arguably, the answer was yes. After all, the Space Shuttle program was managed from Johnson Space Center, in southeastern Houston. All the astronauts who flew on the shuttle trained there. And the vehicle was operated out of Mission Control at the Houston-based facility.

But when the final decisions were being made to distribute the shuttles 15 years ago, the Houston community dragged its feet on putting together a competitive proposal. There were also questions about the ability of Space Center Houston to raise funding to house the shuttle within a new display area, which magnified concerns that the historical vehicle, like a Saturn V rocket before it, would be left outside in the region's humid environment. Finally, other cities offered better proposals for displaying the shuttles to the public.
