I listened to taz and spent an hour reading about tardigrades, and now its my favorite animal. Like - look at it!

It’s practically invincible (can survive at extreme temperatures - -271°C and +100°C), very smol (0,5mm), can exist in space vacuum and live through an apocalypse! It produces a protein that protects its DNA from radiation damage.

When in cryptobiosis (a death-like state of dehydration) they look like a blanket.

They’re also sometimes called water bears or moss piglets, which - valid.

Thanks for coming to my tedtalk.

I desperately needed some methylene blue to troubleshoot my northern blot. Couldn’t find any in my lab (honestly that was a surprise). But it just so happened my friend was giving me his microscope and he had bought some methylene blue! Saved my hide (thank You Lord!) This stained blot tells me the problem isn’t so much with RNA degradation, but that large RNA transcripts aren’t transferred well. So my next step is hydrolyzing my RNA in the gel using a sodium hydroxide salt solution before blotting. Lord-willing this works! (Pray for me)

Meet Sylvia Gravel, a biology/ecology and dance double major from Ypsilanti, Michigan. We asked Sylvia a few questions about her NMU experience so far: 

Why did you choose the NMU Dance program?

Sylvia: I chose the NMU Dance program initially as a minor because I wanted to continue taking classes and pursuing my love of dance. When the dance major was introduced, I decided to take on a double major in order to get the most out of my time at Northern, and to give myself as many options for the future as I could.

What’s an example of a cool, interesting or helpful thing that you have done as a part of your major?

Sylvia: The coolest thing I have done so far as part of the dance major is participating in the Board of Trustees presentation and the Green and Gold Gala. It was a great introduction to the department, and a very rewarding experience.

What are you involved with on campus?

Sylvia: I am a member of the Dance Team. In the past, I have attended Women 4 Women meetings, participated in a few volunteering events, and been involved with my residence hall and house. I also work two on-campus jobs.

What do you love about Dance or the NMU Dance program?

Sylvia: The NMU Dance program makes me feel at home. Dancing is how I can express emotions that I don’t know how to put into words, and the classes here at Northern enable me to do that even in a learning environment.

Outside of school, what do you enjoy?

Sylvia: Outside of school, I enjoy baking and cooking, drawing, and exploring Marquette.

Of your activities on- or off-campus (residence life, student organizations, internships, etc.), what has been the most rewarding and why?

Sylvia: Last year, I participated in the Live Learn Lead workshop series. Unfortunately, due to COVID, we were unable to complete the last workshop, but it was a really good experience. I met a lot of awesome people and learned how to enhance my leadership skills.

What does “be Northern” mean to you

Sylvia: To me, it means taking advantage of every opportunity that comes your way as well as every moment in the incredible environment that our campus is surrounded by.

What are your hopes or plans after graduation?

Sylvia: As of right now, I am undecided on my plans for after graduation. I’m hoping that the rest of my experience at Northern will help me find my true passion.

Why do you wear a mask?

Sylvia: I wear a mask to protect my family and friends, as well as the communities that I am part of here in Marquette and at home.

How have you been practicing social distancing?

Sylvia: I have been practicing social distancing by keeping my social circle small and not attending large gatherings.

How has COVID-19 changed your perspective or your lifestyle?

Sylvia: COVID-19 has made me realize how much I take for granted in everyday life. In terms of my dance life, it has been a challenge, but one that I think will make me stronger.

Here’s why you should never take online feminism at face value when biology is brought up.

I lived for years believing the statement “boys don’t mature fast they just aren’t taught how to behave”. For years I thought that was true. Plot twist! It’s not.

In the womb, females develop first and faster. Fetuses actually are all female at first then grow into male. A quick piece of evidence for you to observe is our genitals. The clitorus is a small and underdeveloped penis.

So what does this have to do with out of the womb and live people? Anyone who has spent a lot of time about babies of different genders will tell you that they are different. You have to speak louder to get a boys attention than you do a girl because of the slower hearing development. Boys typically take more time to speak in full sentences than girls do, too. Same goes with reading.

Child development does not stop at sensory skills, either. There’s the emotional aspect. There’s the critical thinking aspect. Young boys do tend to be more rambunctious and emotional because they don’t yet know how to process this shit. Their brains literally just don’t go that fast.

This is NOT an insult to anyone. This is not to say that boys are stupid and girls are smart. This is not to say that there aren’t anomalies and that the sexes don’t catch up eventually. It’s not even to say that society doesn’t play a role in maturity levels because it absolutely does. There are plenty of cases where boys get away with acting like children when girls don’t. Just like there’s cases of girls being less mature than boys.

This is to say that 3rd wave feminism has basically outlawed science and critical thinking. Sociology is the only reputable field to them and that is so fucked up. By ignoring the biological and psychological facts of the matter, you isolate important components that play a part in behavior. It is so incredibly unfair to point at guys and say that the reason they act so young is purely because of the patriarchy. It boarders on ableism.

I consider myself a feminist but that does not mean I trust the community. And honestly, no one should.

This looks like it could be a game of science Noughts and Crosses, but it’s actually a single intestinal muscle cell being measured for its mechanical force. Essential biological roles, such as cell division and muscle contraction, rely on the mechanical forces generated within a cell. Its dysregulation can lead to loss of function and disease (including asthma, stroke and migraine) so being able to measure cellular forces provides the opportunity for novel therapeutic targets. This video represents the latest technology for measuring the mechanical force of a cell, developed by @ucla scientists.

Savvy Cavy

Who could possibly be more savvy than the Patagonian Cavy, also known as the Patagonian Mara, the Patagonian Hare, or dillaby (Dolichotis patagonum). They’re found throughout the lower half of South America in open, grassy plains and steppes. Although they look more like rabbits and guinea pigs, and is in fact related to the latter, they act more like deer or antelope, and can run almost as fast. They can be incredibly fast runners, but spend most of their time grazing on grasses and flowers. However, they are like rabbits with respect to their breeding habits. During the breeding season, monogamous pairs gather and dig communal dens.  Females nurse young, both their own and others, while the male guards the den and other mothers go out to graze. In this way, protection is ensured for both the parents and the young. When there is danger, cavys on watch will stand up and whistle before darting to the burrow. Young will stay in the burrow for 4-5 months, and then strike out on their own or with a mate. Though maras are monogamous, the males maintain the relationship by following the female and defending her from threats or other potential mates.

Conservation status: Patagonian hares are considered near threatened; their population has sharply declined due to hunting and habitat loss.

100 days of productivity - 0/100

Since tomorrow, I will everyday post about what productive I did. Currently, I am studying many different subjects - some for school, some for exams, some just because I like them. I want to motivate myself & others, I want to order them all, and I just want to take many aesthetic photos- because why not?

I will be posting them here, on Tumblr, and also on my new-made Instagram - @mariaerimos

(While a Nergi likely would have gone after that Magala eventually, I think we just cleared things up before it did. 4/4U are set in the beginnings of an epidemic, which we curb before it reaches critical levels. Same thing goes for previous plot-relevant Elders like Kushala or Amatsu in their debut games. We got to them before Nergi did)

(On a side note to this, my personal headcanon is that outbursts of Frenzy are usually much less damaging or widespread. The Magalas, while still incredibly dangerous like all other Elder Dragons, can live somewhat “normal” lives without causing the destruction of hundreds of ecosystems. That’s why they aren’t as huge of a deal in Generations/Generations Ultimate. I see the Frenzy Pandemic of 4/4U as due to an infant Gore being effected by the Black Blight from Stories, which seemingly takes place before 4/4U due to the Rath Of Meow being created for the first time in that game.)

La genética es una de las ramas de la biología encargada de estudiar las características que se transmiten de generación en generación y estas características se les llaman genes, dichas características pueden ser la estatura, el color de ojos, el tipo de cabello, el tipo de sangre, etcétera y estos genes están formados por pequeños fragmentos de adn y arn, la genética es una de las ramas fundamentales de la biología moderna y tiene varias ramas de estudio como son:

 la genética molecular que se encarga de estudiar la composición función y replicación del adn,

 la genética clásica (o mendeliana) que se encarga de estudiar cómo es que se heredan estas características, la genética cuantitativa que estudia cómo influyen los genes en las características de los seres vivos que podemos observar a simple vista,

la genética evolutiva y de poblaciones estudia el comportamiento de los genes en las poblaciones y cómo influyen en la evolución de las especies,

la ingeniería genética utiliza la tecnología para la manipulación de genes de una especie a otra para añadir las características que antes no tenían.

La genética tiene sus inicios en el año 1865 cuando el monje Gregor Mendel dio a conocer su trabajo el cual consistió en la experimentación con diferentes variedades de plantas de arvejas los cuales cruzó entre sí para observar cómo se transmitían esas características de generación en generación iniciando así las famosas leyes de Mendel dando así origen a la herencia genética.
