Could a graphene filter be the key to helping us drink seawater?

Science may soon make the seas accessible to us, insofar as drinking water is concerned. According to a new study released in Nature Nanotechnology, we may soon be able to desalinate and purify water more easily with a graphene filter. Thanks to the work of an international team of scientists, including researchers from the University of Manchester, Shinshu University in Japan, and Penn State’s Center for Atomically Thin Multifuctional Coatings (ATOMIC), we now have a “sturdy and practical membrane for clean water solutions as well as protein separation, wastewater treatment, and pharmaceutical and food industry applications.”

As it stands, around 1.2 billion people around the world do not have access to clean drinking water, but making use of readily available seawater could be a viable fix. However, “Current desalination methods are energy intensive and produce adverse environmental impact,” wrote Ram Devanathan a researcher at the Energy and Environment Directorate at Pacific Northwest National Laboratory. “Furthermore, energy production consumes large quantities of water and creates wastewater that needs to be treated with further energy input.” A membrane, however, could address these issues.

In essence, the graphene membrane is a sieve that allows certain molecules to go through, while keeping others out. The membrane was created by modifying graphene oxide membranes and the result is a filter that effectively filters out the salt from otherwise impure drinking water.

“Our dream is to create a smart membrane that combines high flow rates, high efficiency, long lifetime, self-healing, and eliminates bio and inorganic fouling in order to provide clean water solutions for the many parts of the world where clean water is scarce,” Mauricio Terrones, a professor of physics, chemistry, and materials science and engineering at Penn State, said. “This work is taking us in that direction.”

In initial tests, scientists found that their membrane was capable of keeping out 85 percent of salt, and while that is not quite pure enough for drinking purposes, it is good enough for agricultural use. Similarly, the membrane was capable of keeping out 96 percent of dye molecules, which are extremely polluting.

The team is not quite done, however. Further research is needed to ensure that this new membrane is a scalable solution and is inexpensive enough to be used by those who need it the most.

There are some spoilers ahead for the ending of Marvel's Thunderbolts. Stop reading now if you don't want to be spoiled.

Earlier this year, Captain America: Brave New World briefly introduced a new direction for James "Bucky" Barnes, a character Sebastian Stan has been playing since 2011 in Captain America: The First Avenger. In Brave New World, the former Winter Soldier apparently retired from being a reformed hero and went into politics by running for Congress. Thunderbolts reveals that Bucky won his election to the House of Representatives. But his stay in Congress was short.

Jeep Compass EV breaks cover—but will it come to the U.S.?
jeep compass ev us newjeepcompassfirsteditionhawaii  4

Jeep just pulled the wraps off the all-new Compass EV, and while it’s an exciting leap into the electric future, there's a catch—it might not make it to the U.S. anytime soon.
This is a brand new electric version of the Jeep Compass, and being built on Stellantis' STLA platform—the same architecture underpinning models like the Peugeot E-3008 and E-5008—it looks much slicker and packs a lot more inside than previous versions of the Compass.
Let’s start with what’s cool: the new Compass EV is packing up to 404 miles of range on a single charge, a 74 kWh battery, and fast-charging that gets you from 20% to 80% in about 30 minutes. Not bad for a compact SUV with Jeep's badge on the nose.
There are two versions: a front-wheel-drive model with 213 horsepower and a beefier all-wheel-drive version with 375 horsepower. That AWD setup isn’t just for looks—it can handle 20% inclines even without front traction, and comes with extra ground clearance and better off-road angles. In short, it’s still a Jeep.
The design's been refreshed too, and inside you’ll find the kind of tech and comfort you’d expect in a modern EV—sleek, smart, and ready for both city streets and dirt trails.
But here’s the thing: even though production starts soon in Italy, Jeep hasn’t said whether the Compass EV is coming to America. And the signs aren’t promising.
Plans to build it in Canada were recently put on hold, with production now delayed until at least early 2026. Some of that might have to do with possible U.S. tariffs on Canadian and Mexican vehicles—adding a layer of uncertainty to the whole rollout.
According to Kelley Blue Book, a Stellantis spokesperson confirmed that the company has “temporarily paused work on the next-generation Jeep Compass, including activities at” the Canadian plant that was originally meant to build the model. They added that Stellantis is “reassessing its product strategy in North America” to better match customer needs and demand for different powertrain options.
So while Europe and other markets are gearing up to get the Compass EV soon, American drivers might be left waiting—or miss out entirely.
That’s a shame, because on paper, this electric Jeep hits a lot of sweet spots. Let’s just hope it finds a way over here.

Charlie Cox singles out his least favorite Daredevil: Born Again episode
Charlie Cox in Daredevil: Born Again.

Daredevil: Born Again season 1 was largely reconceived after the 2023 actor and writer strikes. Dario Scardapane -- a veteran of The Punisher series on Netflix -- was brought in to be the new showrunner and he made a lot of changes to the series that were well-received. However, there's one episode that Scardapane didn't really change at all, and it happens to be the least favorite episode of Daredevil: Born Again's leading man, Charlie Cox.

During an appearance on The Playlist, Cox noted that he wasn't very fond of the season's fifth episode, "With Interest," which was a largely standalone episode that featured his character, Matt Murdock, in a bank during a hostage crisis.
