They say it is edible but the whole growing out of the sack grossed me out on this one so I passed.

… Yeah, that is understandable. Great find! And I like the picture of the gills a lot

Yes, there is a lot of potential. There are micro-spectrometers available covering this range, like the MEMS-FPI type spectrometer or the multi-pixel arrays with filters (example: www.mantispectra.com/products). But this new kind of detector seems to come with higher resolution, faster readout than the MEMS-FPI, and more sensitivity. It is quite exciting, I’m curious to see if they commercialize it soon.

I am not 100% sure, but I think that the designer bears the cost of the wafer yield.

The PDK is specific to the manufacturer, and I imagine that the risk associated with specific features is known and the yield range can be estimated. A design with more and riskier the features would lower the expected yield, and it makes sense that this risk gets passed onto the designer. The contract may have some protections for the case when the yield is significantly lower than expected because of the manufacturer’s fault. Just a guess though, it would be great if someone with real experience can answer.

Very cool!

I also like that they included a device cost analysis. I think they used some aggressively optimistic assumptions (100% yield from the wafer) and large-volume procurement prices that I am skeptical of, but if true it is valuable info.

That’s awesome!! Are they in a terrarium or outside?

It depends. In my experience: in an academic laboratory I have been able to use common sense.

For example, gloves go on when working with strong acids/bases. The statement:

gloves apparently only give researchers a false sense of security that can dull the sense of touch and prevent you from recognizing chemical exposure

Does not apply as much when you are working with such corrosive agents, because you really should never be in a position where spilling 4 M HCl into your hands would go unnoticed.

When working with large quantitites of oils, even if non-hazardous, gloves go on and they will probably get oil in them.

When working with cell cultures, the goal is often to not contaminate the cultures. Some people prefer to wash their hands thoroughly and not use gloves, and they have been working at it for many years and they seem to do just fine. It’s a risk mitigation strategy - if the cultures have antibiotics and fungicides, risk is already not too high.

In an industry setting it is different. Companies often comply with specific standards and health and safety regulations. While the individual can use common sense, the people in charge of ascertaining compliance (sometimes ‘EHS’, Environment, health and safety personnel) aren’t necessarily chemists themselves, nor should they need to be aware of the identity of the transparent liquid in the flask that you are holding. So, generic rules are often set in place not only because of their practical utility but also to simplify enforcement. In some cases external auditors can come in (announced or not) and verify compliance - this, again is much simpler when the rule is ‘lab coat behind yellow line, gloves always on when touching a container with a liquid’ than having to interview each person to understand what they were touching without gloves and to understand their philosophy of why they chose to do so.

This work using high-throughput combinatorial chemistry to find molecules to stop/revert aging is amazing. I have been looking it in the past few days. The authors screened 653,000 different compounds, I am very curious about how expensive this screening was.

I was not aware of DePinho but I am familiar with Schultz’s work. I thought that would get a Nobel prize for his work on non-canonical amino acids, but he hasn’t yet. I am now placing my bets, Ronald DePinho and Peter G. Schultz will win a Nobel prize.

Hello! Welcome!

This reminds me of “the old days” when I was first learning the internet (in a good way!)

Me too! Discovering niche online forums about reptiles and science was very important to me during my teenage years. Finding close-knitted communities with a specific interest made it a lot of fun to explore those interest as well, because to me it felt very personal. Maybe others do see reddit the way I used to see online forums back then, and I was simply too old by the time reddit became big, but I spent 11 years on reddit and I honestly can’t tell you 5 usernames I would recognize.

I feel like the concept of Lemmy might be able to replicate the niche community feeling at an instance level, but at the same time it can provide the more generalized content in the way that reddit does through federation.

My heart skipped a beat too 😅 I think that this is one of the practical difficulties when hosting a public-facing website with user-generated content: how do we deal with the possibility of minors interacting with our sites, from a moral and legal stand point? No need to get into the details here, but it is something that I think about.

Welcome Eight!

What do you do as a field linguist? Sounds interesting

Welcome! All of that sounds super cool! I also dabble in macro photography from time to time.

Isopods and myriapod culturing is something that I haven’t heard about before - I’m curious to visit that community

Thank you! I will have to do a literature search soon to learn about the likely microbes in my body then. I am very curious.

I re-enabled registration. Feel free to use this Peertube instance if you need somewhere to upload that is not YouTube. If (or when) I decide to take it down I will do my best to make sure everyone has enough time and a way to get a copy of their videos, but please don’t rely on the instance as a secure long-term storage! I will try to get around upgrading it soon.

Welcome!! Those are some very healthy-looking garlic bulbs!

Expect posts about ducks, purple-hull peas, and farmers market economics.

Those are some great expectations you’ve set. I have been following a few mushroom growers on YouTube and some of them discuss their experiences with farmer markets. It is a topic that I am very curious about in general! The idea of growing something and then selling it directly to others is one that I find very romantic. When I lived in Oregon I used to visit a local farmer’s market and I really liked the feeling of community while shopping there. Now I live in the Netherlands and unfortunately haven’t encountered a market like that one.

Ahh, it turns out that trying to run a peertube, a mastodon, and a Lemmy instance requires some effort to keep up with moderation and maintenance. Some updates came along and I didn’t have the time to give the instances the proper maintenance, and the peertube instance was being used to upload lots of pirated content as “hidden” videos or to make copies of videos from other sites and not really to upload original content. There were also issues with mastodon filling up my raspberry pi’s SSD because I was not taking care to remove the older content… So I decided to stop being so ambitious for now and only focus on the Lemmy instance, which is my favorite project in the fediverse. If I have the time I might try to “fix” the peertube/mastodon instances but for now I can’t really set that time aside to remember how I set them up in the first place and to figure out the upgrade procedures!

Yeah, editing titles comes in handy. I am not sure why Reddit doesn’t allow this.

Nice to have you around! The microbiome is a very intriguing topic. I am curious about how much we know today about the details. Would you say that as of 2023 we have a decent grasp of the kind of microorganisms that are present under different conditions and their effects, such that researchers are sorting out the details? Or are we still in the early exploration phase, with most of the basic questions still unanswered? I suspect it is the latter.

Hah, thank you for the nice words!

Found the problem. There is a bug in the current version of Lemmy that causes forms that failed in some way when being filled to show the circling arrow forever. Your community Name returned this error and it hung up forever. I’ve looked through the source code and the community name length is limited at 20 characters.
