Ikea's First Smart Air Purifier Comes Camouflaged as a Side Table

Ikea continues to take the invisible approach to its smart home gadgets by camouflaging them as other things. Its new Starkvind smart air purifier is available in two versions, but the better of the pair is cleverly disguised as a small end table, so in addition to removing unwanted particles from the air, you can…Read more...

Greenland Lost Enough Ice in a Single Day to Cover Florida

It’s been a minute since we’ve checked in on Greenland. Let’s see what’s... oh, oh no. The ice sheet covering the island went into a major meltdown last week, and it’s ongoing as we speak. Enough ice melted in one single day to cover Florida in 2 inches (5.1 centimeters) of water.Read more...

Step Inside the Wondrous World That's Inspiring Hayao Miyazaki's Final Film

Genzaburō Yoshino’s How Do You Live? has become a classic in Japan since it was first published over 80 years ago, but until now it’s never seen an English translation. Though it’s a little outside the realm of io9's usual sci-fi and fantasy fare, we’re thrilled to be revealing the cover and sharing an excerpt today…Read more...

Normal Touchscreens Can Also Detect Contaminated Water, Researchers Find

We take for granted that the water coming out of the kitchen faucet is safe to drink, but that’s not always the case in other parts of the world. So researchers at the University of Cambridge are developing a new approach to testing for contaminants using a device that billions of people already use every day.Read more...

Neutron Stars Have Mountains That Are Less Than a Millimeter Tall

A team of astrophysicists recently used new models of neutron stars to map the mountains—tiny raised areas—on the stars’ otherwise perfectly spherical structures. They found that the greatest deviations were still extraordinarily small due to the intense gravitational pull, clocking in at less than a millimeter tall.Read more...

In Biden’s America, You’ll Turn on the Shower and Nothing Comes Out, Just Drip Drip, Can’t Get the Soap Off

For years, Donald Trump’s bathroom fixation captivated the disenfranchised masses, long-suffering from moderate showerhead water pressure, whose dumps deserve to travel down a mighty whirlpool with the force of the Niagara Falls, but, bewilderingly, just float in the bowl. Where the silent majority was too meek to…Read more...

Evidence of Life Could Exist Just Beneath Europa's Icy Surface

Astronomers have modeled the way small celestial impacts have steadily shaped and churned the icy surface of Jupiter’s moon Europa. Importantly, the new study identifies shallow places on the moon’s surface where evidence of life—should it exist within Europa’s subsurface ocean—can persist.Read more...

Biosignature Spotted on Venus Could Be From Volcanoes, Not Life

A team of planetary scientists said that if there is phosphine on Venus, it could have geological—not biological—origins. Their findings suggest that phosphine, a chemical often associated with microbes, could come from a reaction in the Venusian sky kicked off by volcanic eruptions on the planet’s surface.Read more...

A Sunscreen for Pavement Could Help Keep Cities Cool

The heat dome baking vast swaths of the U.S. and Canada has put the dangers of extreme heat on display. It points to the need for urgent adaptation so that cities don’t overheat, and that means reducing the urban heat island. Absent planting more trees, there may be other solutions to help keep cities cooler as the…Read more...

Life Under Antarctica Is Surviving on Pulverized Rock

You might not expect Lake Whillans to be a cradle for life, as it’s freezing cold and lies beneath 2,500 feet of Antarctic ice. But as a team of glaciologists recently reported, it is precisely those conditions that nurture microscopic organisms, which feast on the rock beneath the continent.Read more...

Astronomers Think They've Spotted a Rare Kind of Supernova Only Predicted to Exist

A team of astronomers discovered a supernova they believe was formed after the star’s electrons were consumed by other elements in its core. That would make the supernova an electron-capture supernova, a theorized type of stellar explosion first proposed 40 years ago. This may not be the first of these rare explosions…Read more...

Heat Wave Breaks New Records in the Pacific Northwest on Blistering Third Day

The heat wave centered on the Pacific Northwest has felled records across the region on both sides of the border. But those records barely lasted 24 hours in some cases. Even before the hottest part of the day, the mercury once again reached heights never before seen in the region more known for drizzle than sizzle.Read more...
