If we ever have giant inflatable telescopes in space, you can thank Chris Walker’s mom. Years ago, Walker was making chocolate pudding when he had to interrupt his culinary undertaking to field a phone call from his mother. He took the pudding off the stovetop, covered it with plastic wrap, and placed the pot on the floor by his couch. When the call was finished, he was startled to find an image of a lightbulb from a nearby lamp hovering over the end of the couch.

On a clear day, from the middle of a well-trafficked stretch of reinforced concrete that spans the Snoqualmie River, you can just make out the hulking, ice-covered flanks of Mount Rainier. Locals bring their dogs here to the “High Bridge” to swim on their lunch breaks; high school kids in oversized hoodies pick their way through the raspberry thickets looking for a shady spot to light up.

A quick search lands him on a post advertising $10 magic mushrooms, with a poorly lit photo of said mushrooms.

In the last few years California has gained ground in its fight to protect children from infectious diseases. But new data released this week shows that the state’s vaccination rate declined for the second year in a row. Last fall 94.8 percent of California kindergartners had received all their shots, down from 95.6 in 2016-2017. That drop may look small, but California has about as many kindergartners as Wyoming has people.

California’s Monterey Bay is one of the more pure, more dynamic coastal ecosystems on Earth. Otters—once hunted nearly to extinction—float among towering kelp forests, which themselves have rebounded thanks to the booming otter population’s appetite for kelp-loving sea urchins. Great whites visit from time to time, as do all manner of whales and dolphins. All told, it’s one of the greatest success stories in the history of oceanic conservation.

What if Texas oilmen (oilfolks?) could save the planet from climate change? Hardy-har-har. Given that the Lone Star State ranks sixth in heat-trapping carbon emissions worldwide, just behind Germany and ahead of South Korea, the idea sounds pretty far-fetched. But some recent developments have made the prospect a bit more conceivable. Texas is all about oil and gas.

Every restriction on access to abortion draws the metaphoric walls closer. On who can dispense drugs, on what clinical tests are required first, on how far along the pregnancy can be—the rules are all designed to delay, deter, and delegitimize.

Since the birth of the space age, the dream of catching a ride to another solar system has been hobbled by the “tyranny of the rocket equation,” which sets hard limits on the speed and size of the spacecraft we sling into the cosmos. Even with today’s most powerful rocket engines, scientists estimate it would take 50,000 years to reach our closest interstellar neighbor, Alpha Centauri. If humans ever hope to see an alien sunrise, transit times will have to drop significantly.
