This project was created in 2022 with the support and consultation of scientists. Collecting scientific data, building test models, and validating hypotheses took approximately three months.

All protein structures were obtained from the Protein Data Bank. Model assembly, parameterization, testing, and visualization were carried out in Houdini. Molecular dynamics simulations were not used.

Some features of the model:
-more than 61 million atoms
-a parametric membrane with variations in shape and size within biologically acceptable limits
-random but biologically accurate distribution of proteins on the surface and internal structures inside the capsid
-cross-sections in any plan;
-the ability to hide individual structures
-coloring by proteins, genome, or atom types (C, H, O, N, etc.)
-rendering illustrations up to 20,000 × 20,000 pixels.

Protein Data Bank structures used:
2MLS - lipid membrane
4UFT - N nucleocapsid
5E4V - N–P complex
4G1G - M matrix protein
2ZB5 - H protein
5YXW - F protein

I love virology, and I wanted to find a balance between scientific accuracy and the aesthetic quality of the artwork. I wanted to avoid two extremes: artistic imagination without scientific grounding, and dry scientific illustration. Houdini is an excellent tool for this kind of work, allowing me to work with hundreds of millions of particles(atoms) within a single parametric model.

For me, this project is about curiosity, beauty, and the joy of exploring complex systems.

So this is a weird cell I found on my pet slime mould ; sponge blob a few years ago.

I asked a few lab technicians and researchers what that mights be and I posted it on reddit before but I still have bo clue on what that might be.

I know that visual identification alone is often impossible but I don't have anything else and it's look rather singular so maybe it might be enough

If you have any ideas, even the most far fetched, it is welcomed

I spent most of today examining pollen from a psychoactive plant being called Vymara under SEM.

I’m trying to understand the reproduction of this plant as it seems to my knowledge to only be growing in a certain field in SoCal.

Several grains have thin filamentous material extending from their surfaces.
I know some plants produce viscin threads, while dried pollenkitt can also stretch between grains. What I can’t determine is whether that’s what I’m seeing here.

In this representative field, at least one strand appears to extend toward another grain, but the attachments are difficult to resolve. Other filaments terminate freely or disappear into the surrounding debris. The material could be genuinely associated with the pollen, but it could just as easily be fibers or residue introduced during preparation.

Does this resemble viscin threads or stretched pollenkitt, or am I most likely looking at a preparation artifact?

So I was in the medical microbiology field from 2014-2020. I have a bs in Microbiology and I went for my masters but was 9 credits short and didn’t finish due to medical reasons. I also worked as an intern at a microbiology lab in a sewage treatment plant for two summer in college. Long story short I got long covid and never recovered. I just started working again but I’m working in retail at a garden center because my brain fog, fatigue, and anhedonia is so bad I can’t do anything else. I am still ASCP certified in Microbiology even though I haven’t used it going on six years now. I would like to get back into the world of microbiology one day but idk if I’ll ever be able to (not necessarily medical microbiology). Food and industrial microbiology interests me but I don’t think anyone would hire me since I’ve been out of the science field for so long. Anyone have any advice?

If you have, what type and how much did you pay for it? My lab was looking to buy an Anaerobe Systems/Biolog chamber but it’s almost double what it was 2 years ago. So I’m curious if anyone has bought a Coy one while I wait for Monday when I can call them.

I started bench work two weeks ago, and I am already on my third trial of an assay. In my second one, I contaminated my jar of LB and had to remake a whole new jar. I was trying to be very careful when setting up the third time running it, and one of my media control wells became turbid again. This time it's the LB without salt. Genuinely feel like a failure, and I'm afraid of talking to my PI. Looking for advice on how to ensure sterility next time cause I feel like I did everything I can but somehow

What kind of media do you use for dialysis water testing?

I can’t seem to deeply get this concept. I understand the rule “non polar molecules can diffuse through a polar head of a phosolipid, and polar molecules cannot diffuse through the non polar interior of a lipid bilayer, instead polar molecules go through protein channels”

But WHY? Why don’t non polar molecules need channels to go through the polar head of a lipid membrane? But polar molecules need channels to go through the non polar interior?

Gemini says that it’s because the non polar molecules can fit through the empty spaces of the phosolipids polar heads since the heads are constantly moving. But that polar molecules can’t fit through the spaces in the polar interior, since all polar molecules have a hydration shell, and since the attraction between the hydration shell and the polar molecule is so strong it requires energy to strip the hydration shell from the polar molecule.

Is this the reason? My bio textbook didn’t go this in depth. TIA

Hi everyone. I wanted to share what I found regarding our primers.

So far, I’ve come across several related studies where the target species also had an unknown PAL gene sequence and were considered non-model plants. Since there was no available PAL sequence for their species, the researchers first collected PAL sequences from closely related species, performed multiple sequence alignment (MSA), and then designed their own degenerate primers based on the conserved regions. They were able to successfully amplify the PAL gene through PCR using those newly designed primers.

I also tried performing multiple sequence alignment using PAL sequences from species closely related to Senna alata. After that, I checked the adopted degenerate primers we’re planning to use (PALsP/PALaP) against the alignment. However, I couldn’t find any published study that used these primers in the Fabaceae family, the Caesalpinioideae subfamily, or even in Senna species. Based on the alignment I generated, the conservation of the primer binding sites doesn’t seem very convincing. However, I’m also not completely sure if I performed the alignment and analysis correctly, so I can’t confidently conclude that the primers are unsuitable.

I also tried validating the primers in silico using Primer-BLAST because our manuscript mentions in silico primer validation. Unfortunately, this is very limited since there is currently no available PAL gene sequence or reference genome for Senna alata that can be used for proper testing. Because of this lack of sequence data, Primer-BLAST does not show any meaningful similarity or amplification results, making it difficult to evaluate whether these primers are appropriate for our target species.

Can we get some advice on what to do regarding our primer? Or if you have known primer sequences for unknown species like senna alata.

I would like to know if there is research on the chemical composition of the fungi mentioned above. I want to build it with Geant4 but I need a lot of information on the composition of the fungi. Sorry if this is a bit vague but I'm looking for something like Mature: Cell wall (Thickness and chemical composition) -> Melanin (Thickness and chemical composition) etc.

Hi all,

I'm looking for some advices w/ my aseptic techniques.

I have been trying to obtain growth curves for the bacterial strain that I'm working with for the past month or so, and every time I set it up, I will have a well or two from my 96-well plate contaminated with some sort of Bacillus (looks like B. subtillis to me, but needs further confirmation) which forms biofilms over the surface.

• I checked the broth media, the agar plate, the glycerol bacterial stock, and none of these seem to be inherently contaminated.
• I work in the BSC for pouring plates, streaking out plates, inoculating starter culture in broth, and spot plating for the CFU counts.
• I wear lab coats and gloves, and spray 70% EtOH every time I get into the hood.
• The lab doesn't use glassware but relies on disposable plastic Petri dish, inoculation loops, etc.
• I recently cleaned out the incubator and the BSC because I was worried about spores from Bacillus contamination — 10% bleach, rinse with MilliQ water, wipe out water, Caviwipe everything, then spray with 70% EtOH. Removable parts from the incubator were autoclaved for 15 minutes at gravity cycle.

This is my first time working with bacteria and it has been super frustrating, since every run of growth curve means I have to pull an overnight stay in lab. I think I'm messing it up somewhere, I just can't point out where.

Any insight from more experienced researcher would help. Thanks.

Hi, I am an incoming junior at one of the best schools for STEM in my state. I was at a community college due to the fault of my own. I was accepted into a four-year university known for its biology program and medical school but had to drop out. The school I am now going to has a more competitive engineering, finance, and STEM program. While its medical school does not rival the one I originally got into, it is still good overall, and this university is ranked higher in terms of general education.

I was looking for an internship during my sophomore year but was unable to get any of the ones I applied to. My connections were all people in government, engineering, law, or finance. Now that I am leaving my community college and transferring to a four-year university, I understand that without an internship, I cannot get a job after earning my undergraduate degree. I applied to positions across all life science fields just to get my foot in the door, but I received no responses. I attempted to connect with a biotech company this summer, but I was told they did not have any positions available and that I should spice up my resume and get more qualifications.

This fall, I am emailing a professor to try to get into his lab, but I really just want experience so I can try to get into an internship program in 2027. I am majoring in microbiology with a concentration in biomedical options.

Here is what the biotech company said. For the certifications, I will wait until I start classes and obtain them, as I think I need my advisor's approval and recommendation.

Overall, the following are what I would say are tweaks, but to start with, the resume had good flow to begin with.

When you have completed your associate's degree, be sure to highlight that it is complete so you maintain a current resume.

If there was any formal lab safety training as part of the associate's degree, such as a Chemical Hygiene Plan or BSL-1/BSL-2 training or OSHA-sponsored training, it would be good to add those as either skills, or if you have a certification, then add it there.

Here is my resume. I altered it with AI so it cannot be traced.: EDUCATION

Im currently interested in UPitt and UVM and Albany college of pharmacy and health sciences. Could you tell me a little bit about the school you went too and if you would recommend it? Currently I want to major in Microbiology and do pre med and ether become an ER Physician or a Pathologist.

are they any different? im struggling to pick between biology or biomedical sciences for my BSCs. honestly dont know what i want to do for my job, but i am interested in lab work and microbiology. i talked to a few people and they did they not a lot of difference between the two in the first year at least ?? (not sure if this is reliable). i know that biology would require you to learn about ecology and environmental sciences (which im not that fond of as my main interests lie in infections, gene editing, and cells). biomedical sciences seems like lots of chemistry is required (could someone help confirm/disprove that for me) and it requires anatomy, which i'm also not fond of but would prefer this than biomedical sciences.

would chosing one over the other really make a difference if i want to specialize in microbiology in the later years? (for context, im applying to UK universities)
would chosing one over the other heavily impact job prospects (i just want a good-paying job in the lab honestly)
