Every rush hour, bumper-to-bumper traffic belches out diesel fumes along Madrid's Gran Via, a six-lane artery that bisects the Spanish capital. Art Deco facades line the grand boulevard.

But they're blackened with soot.

"The pollution hurts my eyes, and I can feel it in my throat," says commuter María Villallega, 48, who lives in the city center and walks to work. "I don't own a car myself, and I'll be happy when they're not allowed here anymore. We need to protect the planet, and ourselves."

Update, Wednesday, April 5 at 9:30 a.m.:

The Senate voted Wednesday morning along party lines, 19-13, to move the bill forward. It exempts existing high-capacity wells from review of the Department of Natural Resources if the well needs to be repaired, replaced or sold.

This story starts with the mystery of a missing cow.

University of Utah researchers placed seven cow carcasses in Utah's Great Basin Desert, and set up cameras to learn about the behavior patterns of local scavengers.

But a week later, researcher Evan Buechley returned to one of the sites and found no sign of the cow.

A rain forest sings with the sounds of insects, birds, maybe a howler monkey or two. But scientists are discovering that some forest dwellers also communicate in ways humans usually can't hear — via ultrasound.

A team from Dartmouth College has recorded these signals in treetops on a pristine Panamanian island called Barro Colorado, and slowed them down to make sense of them.

John Dickert has been Racine's mayor since 2009. This summer, he’ll abandon that post to take a job with the Great Lakes and St. Lawrence Cities initiative.

The organization represents mayors from more than 120 American and Canadian cities.

Last January inside Racine City Hall, Dickert addressed a swarm of journalists. They were there to learn about the contentious plan allowing the City of Waukesha to divert drinking water from Lake Michigan.

Earlier this winter, photographer Michael Furtman was driving along the North Shore of Lake Superior in search of great gray owls. Several of the giant, elusive birds had flown down from Canada looking for food.

He pulled off on a dirt road where he had seen an owl the night before. An owl was there, perched in a spruce tree, but a pair of videographers were filming it.

"I backed off; I was going to just let them have their time with the bird," Furtman says. "And then I saw them run out and put a mouse on the snow."

This weekend bicycles are ruling the road in Yellowstone National Park. Most park roads are closed until later this month, but every spring Yellowstone opens about 50 miles of its main thoroughfares to bikes only.

Humans have long looked to animals for design inspiration. From basic camouflage to a quiet bullet train in Japan to the Wright brothers' wings, the process called biomimicry is a basic tenet of human engineering.

Jonathon Keats has turned it on its head.

Here in Washington this week, President Trump signed an order to start undoing some key climate change regulations. The president says they're hurting business.

For the second consecutive year, Japanese whalers have returned to port after an Antarctic expedition with the carcasses of 333 whales. The five-ship fleet, put forth by the country's Fisheries Agency, killed the minke whales during a months-long voyage to southern waters for what it calls ecological research.

River Revitalization Foundation is a nonprofit headquartered in what originally was a brick ranch along the Milwaukee River, upstream from downtown Milwaukee. Surrounded by restored shoreline, the south-facing portion of the building’s roof will soon be topped with ten solar panels.

That’s if Mike Ballo achieves his goal to raise $10,567 to install the panels. The panels themselves were donated to the foundation.

As California water officials confirmed Thursday that the snowpack in the Sierra Nevada remains well above average, pressure was mounting on the state to lift emergency water restrictions that have been in place for two years.

The snowpack across the mountains is now 164 percent of average, a closely watched marker in the nation's most populous state — and biggest economy — where one-third of all the drinking water comes from snow-fed reservoirs.
