The release was part of a program that has saved thousands of turtles and has returned them to the wild over the past 25 years. The turtles were either raised from eggs or were themselves rescued from roads, storm drains or other dangerous places over the years.

"It is (It's) a great community connection,” said Lisa Ferguson.

Ferguson is the director of research and conservation at the Wetlands Institute. It operates the program jointly with Stockton University and Stone Harbor schools.

Matthew Hollingworth is the WFP’s Emergency Coordinator in Ukraine. He said Uber’s technology has improved the organization’s ability to help get aid “to those most affected by the war in Ukraine.”

Dara Khosrowshahi is Uber’s chief executive. He said the company was pleased to offer the specially-developed software to the WFP for free.

He said the system is supporting a network of cars and small vans that can make deliveries to “points within a 100-kilometer radius of WFP warehouses across the country."

Worries about the future of the Mekong Delta increased after an extreme lack of water this year caused the area to become saltier than normal. The United Nation’s Food and Agriculture Organization, or FAO, said rice production fell by 1.1 million tons.

Philip Hirsch is a professor at Sydney University. He says climate change is causing sea levels to rise and bringing more storms to the area. “One of the big concerns is the amount of salt water and the distance the salt water moves up various Mekong tributaries into the Delta, which again threatens the viability of rice farming,” he said.

The government of Vietnam is seeking to help the main rice-producing part of the country deal with difficult agricultural issues.

The area is known as the Mekong Delta. It is home to 18 million of Vietnam’s 94 million people. More than half of the country’s rice is grown in the area, which feeds more than 145 million people in Asia.

The Mekong begins in Tibet. It passes through six countries: China, Myanmar, Laos, Thailand, Cambodia and Vietnam. Some of these countries are building dams that are affecting the river.

FOR DECADES, SCIENTISTS have wondered what to do with the liquid inside a lithium-ion battery. This electrolyte is key to how batteries work, shuttling ions from one end of the cell to the other. But it’s also cumbersome, adding weight and bulk that limit how far electric vehicles can go on a charge—on top of which, it can catch fire when a battery shorts. A perfect fix would be replacing that liquid with a solid—ideally one that’s light and airy. But the trick lies in making that switch while preserving all the other qualities a battery should have. A solid-state battery not only needs to send you farther down the road on each charge, it also has to juice up quickly and work in all sorts of weather. Getting all that right in one go is among the hardest questions in materials science.

In recent months, startups working on solid-state batteries have made steady progress towards those goals. Little battery cells that once sputtered after being charged are growing up into bigger ones that go much longer. There’s still a ways to go until those cells are road-ready, but progress is setting up the next challenge: Once you’ve built a good-enough battery under painstaking lab conditions, how do you build millions of them quickly? “These companies are going to have to have a massive mindset change, going from being R&D companies to manufacturing companies,” says Venkat Srinivasan, director of the Argonne Collaborative Center for Energy Storage Science. “It’s not going to be simple.”

A genome, then, is at least in part a record of the useful knowledge that has enabled an organism’s ancestors—right back to the distant past—to survive on our planet. According to David Wolpert, a mathematician and physicist at the Santa Fe Institute who convened the recent workshop, and his colleague Artemy Kolchinsky, the key point is that well-adapted organisms are correlated with that environment. If a bacterium swims dependably toward the left or the right when there is a food source in that direction, it is better adapted, and will flourish more, than one that swims in random directions and so only finds the food by chance. A correlation between the state of the organism and that of its environment implies that they share information in common. Wolpert and Kolchinsky say that it’s this information that helps the organism stay out of equilibrium—because, like Maxwell’s demon, it can then tailor its behavior to extract work from fluctuations in its surroundings. If it did not acquire this information, the organism would gradually revert to equilibrium: It would die.
