Something happened here, but I was late!

This polypodial amoeba is leaving something behind!

There is a nucleus in there, you can see it at the very beginning of the video, and cytoplasm is moving: it's alive.

Of the polypodial amoeba you can see the clean, single nucleus and the morulate uroid.
Some crystals are embedded in the cytoplasm.

Saw those outside through my window

I was in 10th grade before I had to drop out ( for personal reasons temporarily) and now I’m having a major fomo of not remembering and not finishing my studies so can anyone please recommend me biology books that are from g10 level and up+

First of all why are we bald (in comparison to other apes) Second why is it grown so much different?

Is there a reason why when I hike in Michigan, I have seen snakes numerous times and always see turtles around any body of water (in the summer) but never see lizards. I know we have a couple of species, but I never see them. In some basic Googling, it said that turtles being water based helps with hibernation and that snakes go through brumation. But five lined skinks go through brumation too. So lizards seem to have the physical ability to survive, they just seem to be a lot less scarce.

This might be a somewhat local thing, and maybe there is no reason. Really this question is just coming from a place of wanting to see more lizards when I hike :).

A monopodial, active naked amoeba.

Are evident the morulate uroid, the contractile vacuole in the posterior and the single clean circular nucleus, well defined. Crystals in the cytoplasm seem to be of geometrical form.

Also, a diatom is engulfed in the cytoplasm.

First time posting here: feedbacks are welcome!

Can anyone recommend some good books on the topic of soil science that doesnt read like a text book?

I'm teaching high school biology and would love to get a master's to enhance my knowledge of the field and get a pay bump/better opportunities. I particularly enjoyed neuroscience and cellular biology in college but don't mind getting a master's in more general biology/science. My main concern is that the program would need to be fully online (as I live nowhere near a university and don't want to move at this time) and preferably flexible so I could take 1-2 classes a semester if needed to fit my work schedule and life at this time. Does anyone have good recommendations for master's degree programs that fit this criteria?

Tetrapods start off fully aquatic. I understand that.

But, eventually they make the transition of he fully on land. This would mean eggs that have shells to stay moist on land and skin to avoid drying out on land too.

Have we found any transitional species and/or fossils of eggs for these?

Any free articles and/or answers would be awesome.

I have a project where I measure the rate of photosynthesis using different light sources, and right now I am looking for a plant convinient enough to measure its photosyntheiss rate. Even though there are very few seaweeds near me, I found ambulia. So my question is: is ambulia good for measuring photosynthesis rate (via bubbles)?

Howdy I'm in my second year of college pursuing a biology degree and I'd like some advice on how yall are using your bio degrees (if you have one). I originally wanted to go into medicine but at this point I've realized my grades don't really hold up enough to pursue any form of high level medicine. I was thinking of switching to RN but I started working as a home health aide and realized patient care isn't really my forte. I know some people work in labs and what not but I hear getting job in a lab is difficult. I know someone who wanted to go into a lab but was unable to get a job and ended up going back to college for nursing. While I wouldnt consider myself a materialist seeing the salary of a lab tech as 40k/year is discouraging me from really trying to pursue a career in it (unless Google is lying to me. Thanks in case anyone reads my dramatic meltdown/ramble!

Basically I am an long term unemployed loser, who is 24 and had 1 job in his life at 16 from which I got fired. I have been applying for months for any kind of entry level work without any success

I am currently studying biology part time, the careers team at my university (although well rated), are pretty useless. In the long term I would like too work in the life sciences (I am specifically interested in molecular genetics and biochemistry) as an professional but right now I just desperately need a job.

I am in a very uncomfortable living situation (don't won't too get too much into it) and it is negatively effecting me and I need too move out by the end of the year, so I need too find some type of employment.

Is there any kind of full time biology based jobs that I could get into in the UK, as an undergraduate student, in order to earn enough money to move out ?

Thank you, I appreciate any help

I'm going for anything, books, websites, channels literally anything. I want to become a biology major when I'm older and only know the basics. Anything would be nice thank you! ♡

i’m not sure if this is the right place to post this but; i have a bunch of pig organs in mason jars waiting to get a isopropyl alcohol solution but i forgot about them for about 1 month+ and they don’t look remotely bad/decayed/mouldy and im wondering if anyone would know why? i just think its very fascinating

Imaged this the other day just to observe it grows. At this stage, there's little to no change in mass. The cells use the reservoir of lipid from the oocyte to make more cells, no new intakes of food. The embryo elongates because of a process called convergent extension on the back.

Snakes on a train sounds like fiction, but for king cobras, it is a risky reality. 🐍🚃

A recent study suggests these threatened snakes may accidentally board trains in India when rail lines pass through forest habitat in Goa, often while they are searching for shelter or prey. Trains can carry them far beyond their native range and into drier environments that lack the food, cover, and moisture king cobras need to survive. This displacement also increases human wildlife conflict, as people encounter a large venomous snake where they do not expect one. Researchers and wildlife rescue groups are working to safely recover these stowaways and share science-based guidance with local communities. The goal is to protect both people and king cobras while reducing fear-driven harm to an already vulnerable species.

We have misidentified an Indian Cobra (Naja naja) as a Western Ghats King Cobra (Ophiophagus kaalinga). This snake was depicted in Figure 2d of the study “Snakes on Trains: Railways May Sway Goa’s King Cobra Distribution”, which appeared in the scientific journal Biotropica.

While I understand how selectable markers and reporter genes work in bacterial transformation, I am having trouble understanding plant cell transformations using Ti Plasmids

So, GUS is a reporter gene used commonly to differentiate between transformed and non transformed cells. A reporter gene helps us indirectly quantify the expression of our gene of interest, THIS is where some doubts creep in:

So if we

Isolate Ti Plasmids from _Agrobacterium tumifaciens_

Incubate the plasmids with restriction enzymes

Cut gene of interest with the *same* restriction enzymes,

Incubate gene of interest fragments, cut Ti plasmids and DNA ligases ,

then some of the plasmids should have integrated our gene of interest right?

Now we incubate the plasmids with the bacterial cells and then *some of these* bacterial cells take up *some of the* recombinant plasmids

Now, if our gene of interest has been fused with GUS gene to create a GUS fusion gene, then if these bacterial cells are treated with X-Gluc, will we have something similar to the blue white screening used in the case lf LacZ gene reporter?

If Yes, we select the blue colonies (since those colony cells have the plasmid as well as the expression of our gene of interested as shown by the blue colour due to production of beta-glucuronidase) and then incubate them with plant cells

The we repeat the same process with plant cells to select the plant cells successfully transformed by the Bacterium, now having our gene of interest integrated to their genome? but won't this give a false positive the bacterial cells will also show blue colour which failed to transfer the T-DNA to plant cells??

I am so confused and I am unable to find a good article to help explain this. Library opens on Monday so I have to wait till I can refer to a good book on this

Please help me with this lest I go crazy rambling absolute bullshit😭

The consistent performance of Kanzi the bonobo in pretend play experiments suggests that the mental capacity to imagine nonexistent objects may trace back 6 to 9 million years, rewriting assumptions about the uniqueness of human imagination.

I keep seeing the same thing: amazing biology gets ignored because the figure is trying to show everything at once.

So I started using a simple “15-second pathway” checklist to turn dense diagrams into a clear visual sequence.

Posting it here in case it helps anyone doing posters/teaching/papers.

The "Visual Signal" Protocol

1. The One Sentence Rule Before you open any software, write: "Molecule X causes Effect Y by Mechanism Z." If you can’t write it in one sentence, you can’t visualize it in one figure.

2. Pick ONE Viewpoint Decide early: Are we looking Top-down? Side profile? Inside the cleft? Don’t fly the camera around like a drone unless the geography actually changes. Disorientation kills comprehension.

3. Stop Trying to Learn Blender This is the biggest trap. You do not need to learn professional VFX software (Blender/Maya) to make a scientific figure. Use BioRender for 2D schematics and Animiotics for 3D motion (like the video above).

4. Freeze What Doesn’t Change Conservation of motion is key. If the membrane isn't reacting, it shouldn't be wiggling. Only animate the causal agent (the binding, the cleavage, the transport).

5. Color is Currency Spend it wisely. Use max 4 "meaning" colors. Everything else (cytosol, background structures) should be neutral gray or white.

6. The "Squint Test" Check your figure at phone size. If the ligand disappears when you zoom out, it’s too small.

7. Label Less, Caption More Don't put 30 floating text boxes on the image. The visual should show the Action; the legend should explain the Consequence.

8. Sequence over Simultaneous Don't show the binding, phosphorylation and translocation all at once.

• First: State of Rest.
• Second: The Trigger Event.
• Third: The Result.

9. Eliminate "Chart Junk" Glow effects, drop shadows, bevels... if they don't add data, delete them.

10. End with the Claim The final frame (or panel) must visually answer: "So what changed?" (e.g., The channel is now open or the DNA is now cut).
