Deep in Barrington's horse country, a former equestrian farm is being restored to native wetland and grassland habitat. How's it going?

For decades, four species of invasive carp have been working their way toward the Great Lakes. On their way, they’ve left a trail of decimated native fish populations and injured boaters.

Democratic Gov. JB Pritzker once championed data centers. But as they have scaled up, he’s paused state incentives and his position has evolved to one of “responsible growth.” Republican candidate Darren Bailey has both criticized Pritzker’s pause of the tax incentive program and claimed credit for inspiring it.

Sampling crews removed hundreds of small silver carp from a stretch of the Illinois River that's just 80 miles from Lake Michigan,

Public concern has grown around data centers’ energy usage, noise pollution, water consumption and emissions. Now, as Chicago leaders race to catch up, they won’t be starting from square one.

The belugas are the latest to be rescued from Marineland, a shuttered theme park in Niagara Falls, Ontario, which closed to the public in 2024. Last month, a first group of four beluga whales arrived at Shedd Aquarium.

Though Illinois leads the nation in nuclear energy generation, a recently lifted moratorium on new nuclear power plant construction means the race is on to bring new plants online — a task that can take years.

“I had a better chance of photographing a unicorn,” Luke Dahlberg said of discovering the rare bird.

Barely a week after four beluga whales were transferred from Marineland, a defunct Canadian water park, to Shedd Aquarium, the newcomers have already made an impression on their caretakers.
