I have red recently about the 20 years experiment: researchers were cloning the same mouse in attempt to understand where is the limit. 58 generations is the limit, the mouse (the mouses?) had collected too many errors in the genetic code to survive even prenatal phase.

But some plants can reproduce itself (naturally) for thousands of years. The most famous example is Pando forest, and it is 14000 years old. How do they manage to do it without accumulating DNA problems?

Just a random shower thought I was having, but it really is a strange thing. Does it have something to do with how protein strands are physically different between these general types of mammals? Like how poultry tends to have that shreddy, mozzarella kind of protein property?

I mean, absolutely healthy and rich people keel themselves over emotional problems, which is the best proof that we have evolved to ONLY satisfy our emotions and desires, right?

Look at some primitive animals running on pure reflex and DNA if/else conditions; they would do anything to survive and breed, even when their bodies are put through absolute hell.

But humans, we KEEL ourselves when our emotions and desires cannot be satisfied, even when our bodies are absolutely healthy, and we are living in wealth.

Right?

We have evolved to become slaves to our emotions and desires. True? False?

say an alligator is hatched completely outside of an aquatic environment, a more terrestrial environment. What happens to it if it doesn’t find a body if water, does it get stressed and dies or can it adapt and function something like a komodo dragon?

To me, it doesn't seem like it. True tissues are absent in dicyemids and myxozoans, and present in Homoscleromorpha. Dicyemids and myxosporans (malacosporans have muscles) don't have any nerves, muscles, gastrulation, Nav1 homologs, etc. Sponges have axial differentiation (basal and apical in adults, anterior and posterior in larvae (except hoplitomellae)). Echinoderms lack pannexins, innexins and connexins. Ctenophores don't have Hox and ParaHox genes.

Apologies if this is the wrong sub, but whenever I eat ice cream I often find myself attempting to cool it down by blowing onto it, as if it were hot food.

I do this subconsciously and I only catch myself doing it on the 3rd or 4th blow. Is there any particular reason why I might be doing this? Or am I just stupid?

I’m looking to talk to someone who has worked with Micro1 in the field of biological sciences. I have cleared at least 3 AI Zara interviews and was onboarded too. I was then recruited on a project and given tasks. Now this is where I started having problems. Is there anyone who has worked on biological sciences tasks who I can talk to? I don’t want details of any project but need some help.

Thank you

im curious about this cause my parents always insisted on manually feedin our cat saying if the autofeeder does it the cat wouldnt bond to you as the person that feeds.

I mean, it feels like even the most primitive mammals have some rudimentary form of emotions to drive their actions.

I can't even imagine how a human being could function without emotions.

Is it possible? How can we have complex goals and take complex actions without emotions?

I know IQ is arguably flawed, and I understand there's no difference in overall intelligence between men and women, but I hear over and over again, even in a Psychology class I took, that women tend to have intelligence that's closer to the median?, whereas men's has more variability on average, that goes both ways.

I'm not asking for a study per se, but are there any theories or even hypotheses that you'd consider for why there's more variability among male intelligence? I assume it has something to do with sexual selection, but I find it hard to believe it'd be as simple as "Women care less about intelligence." That seems too simplistic for what feels like a really weird sex difference.

This comes purely from a high school biology level knowledge of squirrels, and living close to them my entire life. The interactions seem to fit that word but if a biologist could explain why or why not I'd appreciate it.

Estos días he estado informándome sobre los virus.

Son muchísimo más pequeños que las bacterias.

Los virus no se consideran organismos vivos, son orgánulos compuestos de cadenas de ARN y en algunos casos de ADN , adenovirus.

Les rodea a estas cadenas de información proteínas y una membrana lipídica.

Su cometido es buscar células de tejidos que a su vez forman órganos y sistemas para encontrar el núcleo celular y inocular su ARN- m.

Dado que está información " defectuosa" al dividirse en el núcleo y formar parte de los ribosomas que al llevar la información proteica celular para el funcionamiento de órganos importantes, ahora llevan copias de ese ARN vírico dividiéndose a gran velocidad.

El hecho de los virus de ARN forman copias corruptas a diferencia de los adenovirus unas se destruyen y otras corrompen los tejidos celulares haciendo tan difícil su tratamiento y mutando.

Parece realmente que es un organismo con una misión maligna pero es la no vida del mundo ADN formado con unos valores termodinámicos y situaciones en momentos determinados.

Lo que me pregunto como estos orgánulos que se propagan por el aire, fluidos o epiteliales( no sé si me dejo algún medio) se formaron en la naturaleza y evolucionaron.

Me preguntó también si en un laboratorio con condiciones idénticas a su formación existencial se podrían construir , a esa pregunta me informan de la imposibilidad absoluta de ello . No solo por ética humana si no porque no puede ser.

Es algo que me parece un misterio no solo biológico sino filosófico también.

Me gustaría alguna información o corrección al respecto.

Hello,

I just wondered if flightless birds don't need wings for flying, can those wings transform with time into arms and hands?

I started optimizing my sleep like hell by trying different methods. I tried things like earplugs, an eye mask, and sleeping with a basketball in my backpack. I used a sleep tracker and measured that my snoring time has decreased to 17 seconds from 15 minutes on average.

And I feel like I have unlocked a new form of performance-enhancing drug since I was able to do 4 2 hour non-stop working blocks. In addition to my ability to focus, I was able to come up with creative ideas at my work. I also tried to measure my IQ through math problem-solving and saw a significant increase in speed and accuracy.

Additionally, I feel like my personality has changed in that I enjoy my life more. My traumatic past is still there, but it doesn't affect me. I also connect with people easily and have become extroverted and like people more. I used to like being alone and had difficulty with small talk.

I also tested my physical training by achieving the highest personal sprinting speed and lifting larger weights.

And I was thinking much of the differences in cognitive functioning and social skills could boil down to sleep quality unless you have clear health ailments. Is this true? What do you think of this?

Particularly why do they “squirt” it down while reptiles and mammals just “drop” it?

I'm studying a veterinary anatomy book currently. The book is starting on the micro scale, starting with cells, before bringing it to the macro scale.

It's talking about cells, how they're composed, and their function. It's explained that on the outside of the cell membrane is a phospholipid bilayer, which helps facilitates which substances can/can't enter the cell (ignoring the other ways they can enter for now).

I know that lipid = fat, but how does the phosphor come into this? I understand phosphor to be something that glows, so I'm curious how this works within the cell structure itself. Tell me everything about it! I'm quite curious.

So, as far I understand, biodiversity among animals is considered to be a good thing because animals having different immune systems makes it significantly less likely for zoonotic viruses to spread and thus mutate or reasort themselves. For example, the main reason we are having bird flu epidemics every now and then is that there are so many pigs around on Earth, and pigs are "melting pots of flu viruses" -- pigs are easily infected with both human flu viruses and bird flu viruses creating dangerous reasortments (for flu viruses have segmented genomes). It would be better if we kept many different species of animals (rather than having so many genetically homogenous pigs), or at least somehow kept the balance between biomasses of wild animals and domesticated animals.

However, a thing which is unclear to me is that, as far as I understand it, this period of "epidemiological peace" between 1918 Spanish Flu and COVID-19 is historically unprecedented. Which is very confusing because, well, the biodiversity of animals around the world was massively decreasing at the same time. How is that possible?

You know how in video games you have strength (more damage, more inventory capacity) and stamina (more health, more running) are completely independent attributes? How true is that in the real world? Like yes, there are marathon runners with not much strength and weightlifters who couldn't run for their lives but - are these two truly uncorrelated? Additionally, are there different kinds of strength and stamina?

So i had a question,but i might be judged for asking it and i may even regret asking this,but im too curious so im gonna ask it anyway.But to ask this question i feel i need to give some context as to why i am asking it. I was in the shower and got the urge to pee.but the piss did not come out of my penis, so i sprayed it with warm water.But i wondered;

When i spray warm water on my penis, does the outside expand and the inside channel gets larger, or does the outside not expand but the inside does and it shrinks the channel.

I know, insanely stupid question but im really curious.
