Does a USB drive get heavier as you store more files on it?
Nope. Paradoxically (and theoretically), the more you save on a flash drive, the lighter it gets.
USB drives use Flash memory, which means the the ones and zeros of the data are stored on transistors.
When you save data, a binary zero is set by charging the float gate of the transistor, and a binary one is set by removing the charge.
To charge it, we add electrons, and the mass of each electron is 0.00000000000000000000000000091 grams.
This means that an empty USB drive (which mostly holds zeros) weighs more than a full USB drive (which has ones and zeros). Add data, reduce the weight.

Application Results
Did you think we forgot about this? We totally didn't.
Thank you for the over 45 applications we received! This was roughly 40 more than we anticipated in receiving, and we could not be anymore thankful.
For the sake of self interest, we would like to anonymously record the results and present them here. Please click on the "read more" button below to view the data.
If you wish to skip to the point: Everyone who has applied has been hired, except for a particularly disturbing woman who shall not be publicly named. Welcome to the family, everyone else <3
Positions
According to the data:
-17.4% were interested in being test subjects, which is good because we need a *lot* of those.
-13% applied for Ecto Biologyst
-10.9% applied for Court Jester (but there can only be One)
Rest of the data for this shall be shared at the end of the post. Remember that we did not collect emails- so the applicants are anonymous
In our "education" section, it appears that the vast majority of our applicants are college undergrad or higher (specifically Bachelor to Masters), which is great.
Apart of our diversity meter, '???' is way more than our human applicants which is. Mmm. Sure.
We have no reason to post this chart aside from the fact that we think its funny how much of the pie chart white takes up. Moving along-
Diversity win!! Majority of you are nonbinary!
When making this section of the application, we did not in fact accidentally forget to include heterosexual/straight because the application maker had a brain fart and forgot straight people existed for a solid hour. No. It was a test, you see. Anyway congratulations to asexuals.
In "second languages", we are pleased to report that the majority of you can speak at least a little bit of Spanish- which is promising.
And now, are top favorite contributions:
We may release a part 2 of the results if met with demand. For now, take this as a parting piece. Thank you once again for applying, and we look forward to seeing you first thing next week.

Okay my fellow ADHDers or whatever else is up with your brains that makes it hard for you to study and study on time and study in a way that you actually remember stuff:
How do you get yourself to actually sit down and study? For me, the "oh shit deadline/exam soon, we can focus for a bit in emergency mode" hasn't worked in a long time now, which leads me now to an exam last week or so I put off to February and another one I would have tomorrow that I'm almost positive I won't go to because I never was in the lecture (clashed with another mandatory one) and only just now downloaded the stuff the professor provided, and I'm about ready to fall asleep so I know I won't manage it in time anymore anyway. And I have two other things I'd need done by tomorrow and I already know I'll cry during christmas break because of being overwhelmed not only because of staying at my parents' and missing my friends but mostly because I'll be overwhelmed at the prospect of January coming up with all the presentations and exams etc etc to get done, next to preparing for my main translation exams in February and getting started on my thesis.
So. HOW do you sit down and actually make yourself study? I came home at 7:30pm today, it's now 3:40am and I'm queuing this so that someone might see and have some sort of advice, because in that time I have finished one sentence of a translation that I'd been putting off for two weeks - ONE sentence - and revised the translation but like, very half-assed. I did not study for the exam although it was RIGHT THERE in my brain the whole time and I KNEW it was the most important thing and still, my brain just went kinda "eh 🤷🏼♀️" and I naturally didn't get my bills or even something I'd enjoy doing done. Just did fuck all for several hours that I swear didn't feel that long.
So, yeah, any advice on how to get yourself to actually START working and then sticking with it would be very much appreciated.

The latest quantum computing news is funny as hell, and mirrors the fiasco with Google's claim a few years ago. They claimed to have done a calculation that would've taken 10K years on a conventional processor, then maybe a few months later a Chinese group proved it was doable in five minutes on silicon. IBM's recent claim has already been refuted, with a research group making a better accurate calculation in only several minutes.
I'm all for quantum optimism, but it is not the era-changer that their marketing makes it out to be. It's also not even useful for anything yet and given the immense cost it's kind of silly. I don't particularly care for investment grifts but I also don't like false information.

A More Realistic Artificial Skin May Lead to Medical Advances - Technology Org

A More Realistic Artificial Skin May Lead to Medical Advances - Technology Org
A new bioengineered skin model could improve testing of skincare products and lead to better ways to heal damaged skin.

University of Oregon researchers have teamed up with scientists with the French personal care company L’Oréal to develop a multilayered artificial skin that more accurately mimics real human skin, and can be grown in just 18 days. The advance relies on a novel 3D printing technique invented by Paul Dalton, an associate professor in the Phil and Penny Knight Campus for Accelerating Scientific Impact at the UO.
The research was published in the journal Advanced Functional Materials.
“This is the first known case of replicating quality skin tissue at full thickness, using different kinds of cells separated by a membrane,” said Ievgenii Liashenko, a research engineer in Dalton’s lab.
Creating an artificial skin isn’t as simple as growing cells in a petri dish. Real skin has multiple layers, with different kinds of cells that perform distinct functions. And in the body, cells are supported by an external network of proteins and other molecules. Called the extracellular matrix, this system helps cells stay in position and communicate with their neighbors, which is key to keeping all systems working properly.
To replicate this complex environment, the researchers designed a two-layered artificial skin, with the layers separated by a membrane.

Researchers from Dalton’s lab and L’Oréal co-developed plastic scaffolds that mimic the extracellular matrix via a network of finely structured 3D printed threads. Then, L’Oréal researchers grew cultured cells in those scaffolds to create the artificial skin, with different cell types growing in each layer. The membrane prevents the cells in the different layers from mixing as they develop.
“Other attempts don’t have the same layering—it actually looks like real skin,” said Dalton, who is the Bradshaw and Holzapfel Research Professor in Transformational Science and Mathematics.
The underlying scaffolds resemble a mesh material made of many spaghetti-like threads, each much thinner than a human hair. To make the porous scaffold, members of Dalton’s team used a 3D printing technique they’ve developed called melt electrowriting. In that technique, an electric field pulls the molten printing plastic from a nozzle into a thin thread, enabling very precise control over the printing.
Some 3D printing techniques can create very fine details, but only small objects, Dalton said.
Other techniques allow easy fabrication of larger pieces, but at the expense of resolution. Melt electrowriting bridges that gap, allowing engineers to create relatively large objects with fine details.
The new skin model can be grown in just 18 days, the researchers found, rather than the 21 to 35 days it took to create previous scaffold-based artificial skin models. That makes it more viable to use in commercial lab testing.

L’Oréal is currently using the artificial skin to test cosmetics and skin care products. Going forward, both Dalton’s team and L’Oréal researchers plan to explore the many other potential uses for the underlying scaffolding in skin tissue engineering.
Other potential skin-related applications include healing diabetic foot ulcers and creating skin grafts for burn patients. Beyond skin, the scaffolds developed by Dalton’s team could support myriad biomedical applications, such as artificial blood vessels and structures to help regrow damaged nerves.
“While we’ve made this big advance with the skin, the design of the scaffold is crucial and could be applied more broadly,” Dalton said. “There are so many diseases and injuries in the world that aren’t being solved, so having an extra tool to try to tackle these is really valuable.”
The materials used in the scaffold are already FDA– approved for use inside the human body, making the path to real-world application smoother.
The fabrication facilities at the Knight Campus make it possible for Dalton’s team to scale up production of the materials, Dalton said. “This is the part of the Knight Campus projecting its expertise beyond UO to influence state-of-the-art research fields globally.”
