Pretty serious science here.
Around 2 weeks ago, after this post, I really got interested in bio hacking, especially implants.
I kinda wanted a magnet, to gain a new sense, but I didn't find a magnet that fits my requirements: to be a round, well tested, small, magnet implant with thin and biosafe coating.
There are plenty of magnets out there, I'm sure after some time, there will be a nice sensing magnet for me.
So, I had to get something else. When looking for implants (incl. magnets), you'll quickly find 'Dangerous Things', I trust them, so I preferred something from them for my first implant.
There is a lot of info on their biohacking forum, I took my time and around a week after reading posts
about people who think they have been chipped by someone I decided to get a NExT.
Like most people, I'll use my implant for convinient access control. Opening doors and stuff like that.
I got the package yesterday, got it implanted today.
I also started taking vitamins yesterday, it's recommened for faster healing, but I should have started sooner.
The installation should be easy, even alone, but I let a professional do it.
It shouldn't be too painful, but since I had the chance, I numbed the area. I hate big needles.
It works like shown in this video and is described in detail in this 10 page guide.
I'll probably make another post about this, but I'll just let my hand heal and hope everything stays clean. I think the positioning is ok, but I'll see where it ends up in about 2-4 weeks afaik.
I was at a Bitcoin Meetup last year, and the point of Bitcoin being "green" - as in the use of green energy came up.
We consider that hydroelectric power is fairly green energy. Or is it? Billy Garrison raised an interesting point which I had never heard before. That the reservoirs for dams release CO2. I had to look into this because it sounds like an interesting phenomenon.
I found this paper: Greenhouse Gas Emissions from Reservoir Water Surfaces: A New Global Synthesis
Sure enough - hydroelectric dams produce greenhouse gasses. It's not a lot but "... these emissions still contribute significantly to global budgets of anthropogenic CO2 equivalent emissions."

The paper suggests 3 sources.
It is entirely feasible that hydroelectric dams are not as green as I thought! I learned something new.
"Mars has just received its newest robotic resident. NASA's Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander successfully touched down on the Red Planet after an almost seven-month, 300-million-mile (458-million-kilometer) journey from Earth."
I've come across this great free website which provides a LaTeX editor and compiler online.
It supports templates from most scientific journals, and also has collaboration features so that co-authors can write a paper in a distributed way.
I'm very pleased with how well it works!
IDigBio is an organization working for the implementation of digitizing museum specimens. The Professor I am working for has been awarded a grant to do just this at our University.
I have been given a task to build an equipment spreadsheet, and meet all the technical specifications for this project and the department. We have an outdated .ppt that describes the manor in which raw data should be stored. But they have not mentioned how to work with your IT department when implementing a Department server. I am going to propose to the department that we implement our own server, I believe I can implement the server for the department and meet IDigBio specifications.
Today our department met with IT, and I feel that they want us to purchase a server through them, and install it on their mainframe in our building. We haven't gotten quotes, but they want to install a "9 spinner - Raid 0" setup, the relationship should be good. Professors must meet the IT departments specifications and all technology must go through IT prior to integration online.
Although the money is distributed in a "Decentralized" manor, I feel as if the IT department is shooting for our department to buy a server that will be integrated into their network.
I'll update this with more periodically. I found this article by PCMag helpful
I studied diamagnetism in university as it is an interesting phenomenon not usually observed in day to day life.
Did you know that you can levitate a frog*?
Frogs are mostly made up of water, which is a diamagnetic material. Diamagnetism is the opposite of ferromagnetism. When you bring a magnet close to metal, there is an attractive force, and the metal "sticks" to the magnet. In diamagnetism, there is a repulsive force. This means that you can actually cause repulsion to "levitate" something against gravity.
In the photograph of the frog, there is a very strong magnetic field, and the frog is pushed up away from the magnet against gravity, which makes it essentially weightless.
Other materials are also diamagnetic. Bismuth metal is one such material, and in fact the most diamagnetic material. Diamagnetism is still a very weak effect, and even the force from Bismuth is minute. Another very diamagnetic material is highly ordered pyrolitic graphite (HOPG), which is essentially layers of graphene. HOPG can be purchased very cheaply and it's fun to levitate using magnets.
Here's a thought: You can levitate HOPG on a permanent magnet and it will stay levitating basically forever. Where does the energy come from to counter gravity? (it's a trick question)
