Another interesting experiment. When a positron (antimatter electron) annihilates, it releases 2 gamma rays. Typically these come out 180 degrees from each other. Here I've got 2 gamma probes 30cm apart, with some K40 in the middle. This sharp spike should be those 511kev gammaspic.twitter.com/MTSJZHjoAv

I now have 2 functional gamma ray detectors so I've got them set up to do coincidence detection, aka the program only triggers if something sets off both detectors at the same time. I've got them stacked on top of each other aimed at the sky. The big peak (right) is ~1000 muons!pic.twitter.com/OEHKVxrY3K

Growing Human Neurons Hooked Up To Electrodes Philosophers have long mused about the concept of a “brain in a jar”, but thus far, it’s remained the preserve of science fiction rather than reality. However, after reading some scientific papers, [Justin] …https://hackaday.com/2020/02/02/growing-human-neurons-hooked-up-to-electrodes/ …

My first attempt at making mille-feuille came out pretty well! Super tasty and I think they look pretty great. Two types here, plain vanilla and lemon strawberrypic.twitter.com/eA9L7UaGFw

First video on the new channel! Had so much fun making this and it tastes even better than it looks. Check it out! https://www.youtube.com/watch?v=Sxy_UDbnr48 …pic.twitter.com/LmDomFmNiX

If you haven't already, check out my new instagram for the new food channel. Here's bruschetta with balsamic vinegar pearls. I think it looks really great and tasted even better. https://www.instagram.com/p/B72coLSlFJC/ pic.twitter.com/a907XYai9c

Cameras ready?
Set clean?
Knives sharp?
Ingredients?
Apron clean?
Ok action in 1... 2...
Wait.... I forgot to buy garlic. DAMN IT. Back to the store I go... :(Hvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
Do I know anyone with an Xray fluorescence spec who'd be willing to test a sample for me? Trying to figure out precisely what mineral is in a sample for a video

New video! Going through the whole process of genetically modifying bacteria. It's much easier than you'd think if you've got the right tools and materials, you could do it in a kitchen if you really wanted. https://youtu.be/F0_q-fD_lyU pic.twitter.com/zxOKuVGLKC

Decided I wanted to try nuclear gardening and am gonna have someone irradiate some seeds with a medical linac to see what weird plants it makes. What plants should I get them to irradiate?

On a whim I decided to have a piece of DNA made. It expresses a blue chromoprotein in mammalian cells. Partly this is to test the food safety of the protein for later experiments, but also it'll just be a cool reporter plasmid I can add to addgenes repository. this is the color:pic.twitter.com/oNQvpd82rx

Managed to finally transform some bacteria with a plasmid that makes them bioluminescent. Last one I needed for the video and now I can stock up on the DNA so I don't run out again. I love this color! Maybe I'll grow a flasks worth just for funpic.twitter.com/fr24ypoaRj

The entire inside of the kiln is covered in a layer of ruby. I should've waited for it to cool more, this only shows the largest bits but the entire inner surface now glows pink. Now to get it to grow in one spot rather than coating everything...pic.twitter.com/SWSdDDparM

We melted a fire brick. Well, we melted several but this one turned into a puddle. These are rated to ~2000C. We also made a pile of ruby before running out of oxygen. Thursday we should be able to make some massive chunks of rubypic.twitter.com/TcerLNjtf3

Ironically, these quack BS negative ion bracelets are so consistent in the radiation they put out, I've taken to using them as my check source for calibrating my gamma spectrometer. And they're safe to handle since the thorium is contained in plastic

A few people were asking if the rubies we made yesterday were fluorescent. Yup!! Super vibrantpic.twitter.com/7swNUa0zf0

Success! First go at making rubies. We made these using a laser cutter XD tomorrow we do this for real with oxy acetylene and make much larger piecespic.twitter.com/t7x6nalZjJ

Decided to order a bunch of fun new plasmids. Gonna get the b-carotene one I mentioned yesterday, one that converts b-carotene into astaxanthin, a purple and a blue chromoprotein, and one that make the bacteria change color when exposed to light. SO excited!!
