“Inferno”

Nothing showcases the incredible power of our atmosphere like storms, and no one does stormchase photography like Mike Olbinski. In this vignette, he shows a stunning line of supercells caught near sunset on July 17, 2022. The high shear–combined with the setting sun–put on an incredible show. Dust blown up in a haboob, microbursts and downpours in the distance, and lots of churning, roiling turbulence. (Video and image credit: M. Olbinski)

From coffee-like swirls to atmospheric chaos, a data-driven model reproduces turbulent particle motion across scales using auto-regressive learning with memory effects.

Retreating Glaciers Risk Tsunamis

On 10 August 2025, the slopes of Alaska’s Tracy Arm Fjord gave way, sliding into the water. The resulting tsunami was the second-largest ever recorded, with a 481-meter runup after a 100-meter initial wave that moved at more than 70 meters per second. The fjord was fortunately empty at the time, though it is regularly visited by cruise ships. After the landslide, a seiche ricocheted through the fjord for 36 hours.

With no earthquake to trigger the tsunami, researchers had to piece together the accident through forensics. Their study concluded that the glacier’s retreat had left unstable slopes exposed, likening it to a child’s closet overstuffed with hastily gathered toys. The moment the door is no longer held closed, everything comes crashing out.

Ultimately, the landslide-induced tsunami is, therefore, a result of climate change. That result is disconcerting, given the increasing frequency of cruise ships visiting glacial fjords. Unlike earthquake-induced tsunamis, landslide-induced ones like the Tracy Arm event don’t come with a seismic warning. With rapid climate change and frequent tourism, risk management is critical.

Ever wondered why you get déjà vu or see "ghosts"? According my theory, it isn't a "glitch in the matrix," because nature is a continuous, self-correcting analog organism.

Moths Taking Flight

Insect flight is vastly different than the aerodynamics engineers learn around aircraft. That’s particularly apparent looking at these tiny moths taking off and flying in slow motion. Almost every feature seems, at first glance, aerodynamically wasteful. Hairy, scaly surfaces instead of smooth ones? Relatively small wings for their body size? Moths break our engineering intuition.

For moths, flight is an inherently unsteady process. Every stroke of its wings cups and flings fluid away in an effort to generate enough lift to stay aloft. Notice how the wings flex with each stroke. Part of the moth’s efficiency comes from that flexibility, even though keeping wings relatively stiff is the norm for engineering larger fixed-wing craft. And those hairy surfaces? Not only can they help camouflage insects; they keep them hydrophobic so that water bounces off them. (Video and image credit: Ant Lab/A. Smith)
