Researchers at Nagoya University have created a more efficient iron-based photocatalyst that could reduce the need for rare and expensive metals in advanced chemistry. Unlike earlier designs, the new catalyst uses far fewer costly chiral ligands while still precisely controlling the three dimensional structure of molecules.

Scientists have unveiled a breakthrough way to turn natural gas—long burned as fuel—into valuable chemical building blocks for medicines and other high-demand products. By designing a clever iron-based catalyst powered by LED light, researchers managed to activate stubborn molecules like methane and transform them into complex compounds, even creating the hormone therapy drug dimestrol directly from methane for the first time.

Doug Hayes of Richmond, Virginia, has sent some dance photos (H. sapiens in action). Doug’s captions are indented, and you can enlarge his photos by clicking on them.

The most recent photoshoot with Starr Foster Dance. The company is currently rehearsing new choreography for their upcoming show, “Shouting Distance” which will premiere April 9th – 12th at the Firehouse Theater. Once again, my friend Starrene Foster asked the dancers to perform several leaps, some derived from the choreography that will be performed during the show.

A basic group jump. While it looks simple, it took a couple of tries to get everyone off the ground at the same time:

Molly does an easy leap:

Starr had an idea to photograph Shannon looking into a hallway. The door was featureless, painted dark gray and the floor where Shannon is standing was the same light gray as the hallway floor and walls. Starr asked if I could make the door look like an apartment door and make the floor hardwood. Rather than spend several hours looking for proper flooring and doors, then doing the tedious compositing in Photoshop, I turned to AI. Google’s Gemini AI has a photo editing feature called “Nano Banana” – I’m not making this up. Nano Banana is incorporated into the latest version of Adobe Photoshop, but one has to pay to use it when editing high resolution images. By logging into Gemini AI directly, Nano Banana is free to use unless you need to use some of the more advanced editing features. It only took two prompts to get the result I wanted and only about three minutes to get the final image. There is a second image featuring Shannon at the door, but the AI made two different-looking doors, and the hardwood floor was different in each. It took about three prompts to get Nano Banana to understand that the doors and floors should match, but it finally “understood” and gave me what I wanted. I have been using AI for the past few months to restore old faded and damaged photos. The results have been amazing and saved hours of tedious retouch work in Photoshop. While AI has gotten better, it still requires human input to correct some errors. In the photo of Shannon, the AI put a doorknob and deadbolt on the right side of the door. Sometimes I wonder if the computers are just screwing with us to see if we notice.

The electronic flash units have a “freeze” mode which fires the flash in sync with the camera which is in burst mode – about 15 frames per second or the equivalent of a 1/10,000 of a second shutter speed.

Saturn’s largest moon, Titan, may have been born in a colossal cosmic crash. New research suggests Titan formed when two older moons slammed together hundreds of millions of years ago—an event so violent it reshaped Saturn’s entire moon system and may have indirectly sparked the formation of its iconic rings. Clues come from Titan’s unusual orbit, its surprisingly smooth surface, and the strange behavior of the tumbling moon Hyperion.

Pouring 65,000 litres of sodium hydroxide into the Gulf of Maine removed up to 10 tonnes of carbon dioxide from the atmosphere without harming wildlife, according to the researchers behind an ocean alkalinity enhancement test

The dinosaurs were wiped out by an asteroid, but does that mean we risk suffering the same fate - and should you be worried about the possibility? Leah Crane sets the matter straight

Engineers at UC Davis have built a remarkable device that creates power at night by tapping into something we rarely think about: the vast cold of outer space. Using a special type of Stirling engine, the system links the warmth of the ground to the freezing depths above us, generating mechanical energy simply from the natural temperature difference after sunset.

Green hydrogen could be a game-changer for the clean energy transition—but right now, it’s too expensive and still relies on harmful “forever chemicals.” A new EU-backed project called SUPREME aims to fix that by reinventing how hydrogen is made. Led by the University of Southern Denmark with partners across Europe, researchers are developing a PFAS-free electrolysis system that slashes the use of rare metals like iridium and dramatically cuts costs.
