I helped write an open-source textbook for Penn State and it was PUBLISHED TODAY!!! If you’ve ever thought, in passing, “Gee, I wish I knew more about the hardcore taxonomic science of critically understudied insects”, this is the book for you!
I wrote the chapter on Vespoidea (pgs. 384-406).

'Surprising' hidden activity of semiconductor material spotted by researchers
New research suggests that materials commonly overlooked in computer chip design actually play an important role in information processing, a discovery that could lead to faster and more efficient electronics.
Using advanced imaging techniques, an international team led by Penn State researchers found that the material that a semiconductor chip device is built on, called the substrate, responds to changes in electricity much like the semiconductor on top of it.
The researchers worked with the semiconductor material, vanadium dioxide, which they said shows great potential as an electronic switch. They also studied how vanadium dioxide interacts with the substrate material titanium dioxide and said they were surprised to discover that there seems to be an active layer in the substrate that behaves similarly to the semiconductor material on top of it when the semiconductor switches between an insulator—not letting electricity flow—and a metal—letting electricity flow.

Registration for Penn State’s annual WaspID course is now open! The course will be held over 2 weeks from January 15-26 2024 with the option for both synchronous and asynchronous virtual lectures.
The WaspID course includes:
Lectures and workshops by over 20 leading Hymenopterists from around the world (including me!) about wasp systematics, taxonomy, biodiversity, morphology, and biology; how to collect and rear wasps, insect preservation and curation, and identification and recognition of all 100+ extant wasp families (including 20 new families just discovered this year!)
Access to the brand-new 2nd Edition of the open-source textbook Biodiversity and Classification of Wasps (which I helped write)
Access to literature lists, identification guides, and 3D specimen images
An opportunity to network with hundreds of other wasp enthusiasts and researchers
The option for graded assignments and course certification for university credits

Backyard insect inspires invisibility devices, next gen tech
Leafhoppers, a common backyard insect, secrete and coat themselves in tiny mysterious particles that could provide both the inspiration and the instructions for next-generation technology, according to a new study led by Penn State researchers.
In a first, the team precisely replicated the complex geometry of these particles, called brochosomes, and elucidated a better understanding of how they absorb both visible and ultraviolet light.
This could allow the development of bioinspired optical materials with possible applications ranging from invisible cloaking devices to coatings to more efficiently harvest solar energy, said Tak-Sing Wong, professor of mechanical engineering and biomedical engineering. Wong led the study, which was published in the Proceedings of the National Academy of Sciences.
So this year for Christmas, I decided to remake some things I'd made for my parents years ago now that I have different skills, and am better at fiber arts in general. The thing I'm remaking for my dad is a Penn State themed scarf, but I thought he could also use a pair of mittens. I couldn't find a pattern I liked, so I designed my own! It's the first time I've ever designed my own colorwork pattern, and on top of that it's the first colorwork mittens I've ever made. There's a few things I'd change on a second go, but for a first draft of this pattern I think they turned out really nice. I'm especially proud of the way the paws turned out, and am considering making a second pair with just the paws on both sides.
More details under the cut:

Inside of the mittens:
Plus a bonus of what my floats ended up looking like:
I tack down my floats when they're 3 or more stitches long (so floats are only 1 or 2 stitches long) because I find that improves my tension when doing colorwork.
DM me if you want the pattern and I can give you more details about it.
