No longer content just listening to them rattle around in the glovebox, I finally got a few rolls of film from back in December developed and scanned.

A landscape photo of snow covered mountains looking over a lake in the middle distance. Yellow brown scrub covers the foreground. An overcast sky adds to the contrast of the mountains. A slightly different angle of snow covered mountains looking over a lake in the middle distance. Yellow brown scrub covers the foreground. An overcast sky adds to the contrast of the mountains. A bridge cuts across cold, inky water surrounded by white snow cover and patches of dry yellow and black brush. The bridge from afar, with more mountainous bluffs visible in the distance. Light dappling through the cloud cover illuminates one bluff in gold agains the others.

Another panorama from Ontario's Sleeping Giant Provincial Park taken this past summer. The Giant can be seen resting on the horizon, behind the "Sea Lion" rock formation.

A panoramic color infrared photo of "The Sea Lion" rock formation inside of Ontario's Sleeping Giant Provincial Park. The giant itself bookends the left-side of the image above hazy red trees. Pops of out of focus pink and yellow cover the righthand side. The waters below rock about in impasto'd acrylic hues of powder and steel.

A color infrared photograph of a basketball backboard with a broken hoop. The net has been cut off and the metal rim hangs like a clock face. Red leaves cast natural shadows. A cloud passes through the hoop.

MISO: microfluidic protein isolation enables single-particle cryo-EM structure determination from a single cell colony.

Or from a single dish of HEK cell culture in the case of two membrane proteins.

Out in Nature Methods now! lnkd.in/gpyBSceg

Wonderful collaboration with the Efremov lab.

At the heart of Purdue University's campus, the Engineering Fountain (and totally not the Atari logo) sublimates into brilliant white light, as red auroral curtains dance overhead

A long walk turned into a much longer walk doubling back home for a tripod, then ambling around my university's campus for a couple of hours.

#Photography #Aurora #LongExposure
A satellite is silhouetted against striated bands of greens reds, yellows and purple aurorae punctuated by bright white stars. A long exposure shot of trees standing against bright pink, green and purple aurora overhead. A dark path snakes along the tree-line. A panoramic crop of students looking up at the aurora, each holding cameraphones to take long exposure photos to share with friends and family. A 1/4 s exposure is used, freezing most students in place, as they stand still to take their own shots. A scooter lights the scene in red and blue light. A non-de noised shot of a pink to blue/green aurora gradient against silhouetted tree branches, their leaves freshly fallen with the past week's cold snap.

A local spin on Iceland's "Sun Voyager" sculpture, featuring a university crew team's boat rack in the foreground, during the first few minutes of this past week's solar activity.

Stacking my phone, keys and wallet beneath the lens worked in a pinch as another #CraftyTripod

One of the first few serendipitous shots taken out on a walk during this Tuesday's burst of solar activity.

It's rare that alerts of "possible aurorae" have materialized into atmospheric fantasia near me, so ended up using a bollard as another #CraftyTripod for the year.

#Photography #Aurora
A long exposure photograph of a bridge, with multiple lampposts yellow lights streaking across a smooth river flow. Traffic lights are visible streaking left to right as is the faint green glow of aurora overhead.

Two panel meme from 2001's The Lord of the Rings: The Fellowship of the Ring. Top Text: "After all... why not?" Bottom Text: "Why shouldn't I crank the saturation?". The bottom panel is unnaturally saturation boosted.

It’s my working theory that seniority is directly related to the size (or #) of screens an audience member loses themself in:

• trainees typing on phones
• profs reviewing drafts on ipads
• this guy, 26 min over, turning to read his own projected slides

At an academic conference, it is inevitable that the worst talk will be by a late career Professor who not only think the rules don't apply to them, but will have not even noticed the rules in the first place.

No Kings protest in Greater Lafayette, Indiana on October 18th, 2025 #NoKings #Photography
A child holds a sign that reads "No Kings in America" on the way to the start of the march. An event organizer speaks into a megaphone. A US flag is visible in the background, as is the Lafayette courthouse and a protester holding a crossed out crown poster. Protestors march holding an "Indivisible" banner. Dozens of signs are held high, and some people are looking directly into camera. A zoomed out image of the protest as thousands of people walk onto the pedestrian bridge between West Lafayette and Lafayette.

We Can Stop Deadly Hospital Outbreaks - So Why Aren't We?

Genomic surveillance can prevent outbreaks from spreading, save lives, and costs.

So what’s holding it back from being implemented in hospitals?

Just published, a study describing a taste-based flu test yes, chewing gum that could tell you if you have influenza. The gum contains a sensor that detects the flu enzyme neuraminidase & releases a compound called thymol that changes taste when the virus is present.

Another couple from this past summer. Taken about an hour and 580 m / 1900 ft in vertical elevation apart. Much easier juggling two cameras on the way down than up!
A color infrared view from atop a 1000 ft (300m) cliff looking over the waters of Lake Superior below. Pink watermelon trees contrast cobalt blue waters and charcoal bluffs in an almost two-toned final image. A row boat washed onto a sandy beach around twilight, with creamy sunset colors still reflected in background clouds and water. Sail boats dot the inlet behind the row boats' shallow depth of focus.
