Infographic on the chemistry of the colours of autumn leaves. Green is caused by chlorophyll, carotenoids and flavonoids give yellows, and oranges come from carotenoids, which also contribute to reds along with anthocyanins.

We're firmly into autumn in the Northern Hemisphere, so it's once again time to share one of my favourite chemistry infographics on the kaleidoscope of chemical colours found in autumn leaves! 🍂

This is a great shot of a bee! You got it doing it's thing!

Whoever looked at animals and decided that they were not conscious, or that we were somehow qualitatively different? And why did we believe them?

Ha. By 2030 you will have made 30 cool new things and has 30,000 more ideas. :)

Several 4x6 index cards with color pencil illustrations and simple details about some of the native plants I will be selling at the upcoming markets. The cards are inserted into protective recipe card sleeves.

Desperate times call for creative measures. I will be selling at my first market in a week, and I do not have a color printer, plus my funds are limited. Doodling these plants takes me less time than to create a digital card to order prints. I think it works better for my branding, too.

So lovely!! You've created a keepsake / scrapbook memory for each plant!!! I love it!!

Happy white girl eating vegan mango ice cream on a cocoa flavored cone... And yeah, said girl has a bunch of grey in her black hair, but age is a state of mind! Nobody is old at Cajou!!! And Baltimore is the best!!

Today in Baltimore, on Howard Street, on the same block as Current Space and a few blocks from Lexington Market I had the best vegan ice cream at my favorite place, Cajou. Cajou is French for cashew!

“David Baltimore, a biologist who in 1975 won a Nobel Prize for a startling discovery that seemed to rock the foundations of the fledgling field of molecular biology, died on Saturday at his home in Woods Hole, Mass. He was 87.”🧪🩺

Telescopes Reveal Surprising Chemistry of a Rare Interstellar Object Passing Through Our Solar System Called 3I/ATLAS, the object is only the third of its kind known to astronomers, and it’s likely been heading our way for billions of years, carrying pristine material from another star system

Nice short discussion of the evolving understanding of 3I/ATLAS as this interstellar comet continues its approach to the Sun and more observations come in from various telescopes, featuring a lot of the observing folks 🔭☄️🧪

This is important.
These are just a few of many more scientists who have been affected by NIH cuts.

Federal funded university research is where most breakthrough drugs & treatments are born, such as

HIV-Descovy
Diabetes-Ozempic
Prostate Cancer- Xtandi

And more.

Tentative IDs: yellow-haired sun fly (left) and black-margined flower fly (right) but let me know if you have other ideas!

Also important to note: unlike bees, these guys will pollinate your garden but never sting you. Also the larvae often eat aphids & other pests. What now bees

I hope they don't conclude that Riker was cool.

COMIC: Exploring the ocean's wonderous, mysterious depths Scientists are far from knowing all of the complexities of Earth's ocean. With this comic, we explore some of what scientists do know, like its role as one of the world's largest carbon sinks and how…

I made a series of comics with @npr.org about the ocean! This is the first of three: an introduction to the ocean zones.

a snippet of a mini-comic, at top - straight line stretches from point A to B. Immediately below, same dot at A, then becomes a curving, meandering line that winds through the page and ends at a point with rays and a question mark emanating from it. Text reads: "Nothing can do this for you - that robs you of experience and conflates answers with learning. Rather, it's all the decisions you make along the way, the mistakes, struggles, and surprises! These pathways you create - this is learning.

my statement on Ai from the mini-comic I'm making as syllabus for a new class I'm teaching this fall. It's simple, but I pretty much said all I have to say on it - it robs you of decisions and struggle - and the joy of being surprised. It robs you of learning...

I was just down there a week ago. Union Station is crowded and a happy place to be: crime is definitely not on your mind while your anywhere near this area. What is this doing to traffic? It must be a nightmare!

Third option: you will be welcomed with open arms! Actually, everyone will assume you are from Baltimore. Especially with the flag on them, yeah, you're in!

Yeah. I saw it when someone else mentioned it. Additionally, the 5 cities he's targeting are run by Black leaders.

I live in Baltimore, and this painting hangs in the downtown branch of the Pratt Free Library. It is an accurate depiction of summer in parts of Baltimore. I've been living here for 6 months and once you get acclimated to the sound, it's no big deal.

Sharing some pictures from my decade in #BeautifulWashingtonDC

Come to the opening of the Sweaty Eyeballs animation festival at the Area 405 gallery in #baltimore. There will be many interactive #videogame art installations, including my own VR piece.

Friday, August 22nd, from 5-9pm.

The show will be up from Aug 22 - Sept 12.

Protestors can be controlled with the National Guard, so DC is first choice!!
