Born as 3rd daughter in a culture where birth of a daughter is resented by many, my parents had to deal with 'eerie' solutions from society to get rid of the "burden" that I was about to become. But, my visionary parent-warriors had their armours on! 😇

Looking for ways to bring discussions of #racism in your #science classes? Some ideas I use in class & in talks e.g. genome-wide sequencing studies, databases are skewed. Must be accounted for when extrapolating these data (e.g. personalized medicine) nature.com/news/genomics-… 1/n
Especially when those findings are used to develop decision #algorithms otherwise #racism gets "baked in" #ArtificialIntelligence is not neutral. Healthcare outcomes reflect societal racism nature.com/articles/d4158…

Which means that structural #racism can kill #cancer patients "Black patients with breast cancer and other malignancies face historical inequities that are ingrained but not inevitable" acsjournals.onlinelibrary.wiley.com/doi/full/10.10…

#astrobiology #biochemistry #complexity
What properties characterize life? The search for a fundamental theory of #biology continues to face some serious challenges:
• n = 1
• no unified math
• can't modify carbon experimentally
• biology is still process-description

Hilo de 15 tweets.

1907.

Hoy, 27 de mayo, nacía RACHEL CARSON (f. 1964), bióloga marina y conservacionista estadounidense considerada la precursora de la conciencia medioambiental.
Rachel Louise Carson elaboró una reflexión, a la vez científica y poética, sobre la situación del medio ambiente.

Sus primeros libros cosecharon un éxito inesperado en este género literario, lo que le permitirá consagrarse a la literatura, viniendo del mundo científico.
Tendió un puente entre ciencia y militancia y encabezó el nacimiento de una toma de conciencia social sobre los problemas del medio ambiente.

Nació en Springdale, Pennsylvania.

Se graduó en el Pennsylvania College for Women (Chatham University) en 1929.

1. Mandated #MRNA vaccines are coming. fool.com/investing/2020… The fear campaign of #Covid19 has failed. People are not scared any longer of #Covid, but that's not the problem anymore and truthfully Covid never was.
2. The problem is now that #Covid failed and you are
seeing this chess game of #totalitarian control unfold,
let me tell you what is really coming. If this is a
#mandatoryvaccine campaign and it gets rolled out
rapidly, you better be aware, educated and terrified.
3. #Globalists in the next 2-3 months will magically find the
cure for #Covid and roll it out in a mass #vaccination
campaign. This #vaccine is #MRNA vaccine. This roll out
will come out very fast for two reasons.

متصفح مصمم للجينوم
(genome)
والذي تم تطويره من قبل العلماء والباحثين في معهد
Wellcome Sanger institute
يتم من خلال هذا المتصفح قراءة وتصور سلسلة DNA 🧬 للبكتيريا. Image
سـ أذكر هنا في سلسلة هذه التغريدات عن:
١-مقدمة تعريفية عن الجينومات البكتيرية
(bacterial genome)
٢-أهمية متصفح الجينوم( genome browser )
٣- كيف يساهم هذا المتصفح Artemis في دراسة مسببات الامراض البكترية
#biology #Bioinformatics #gene #Bacteriology
تمتلك الجينومات البكتيرية مجموعة من الأحجام ويمكن أحتوائها على واحد أو أكثر من الكروموسومات ويمكن ان تكون هذه الكروموسومات دائرية أو خطية (circular or linear).وبغض النظر عن شكلها تظهر الجينومات البكتيرية ارتباطاً كبيراً بين حجم الجينوم وعدد الجينات الموجودة في الجينوم. Image

Extravagant success of Ashkenazi #Jews in wide range of intellectual domains serves as solid refutation to already exhausted #woke narrative of oppression, victimhood, & intersectionality. Why?/1

#IQ #psychology #intelligenceresearch #groupdifferences
"In the first half of the 20th century, despite pervasive and continuing social discrimination against Jews throughout the Western world, despite the retraction of legal rights, and despite the Holocaust, Jews won 14 % of Nobel Prizes in literature, chemistry, physics..."/2
"..., and medicine/physiology. In the second half of the 20th century, when Nobel Prizes began to be awarded to people from all over the world, that figure rose to 29 %. So far, in the 21st century, it has been 32 %. Jews constitute ~0.2 % of the world’s population."/3

Today we launch the @ECHO_ERCproject online!🥳
ECHO is lead by Alberto Palloni & financed by the @ERC_Research #H2020 programme🇪🇺
The project started on March 2019 and will run until 2024, hosted at the Institute of Economy,Geography and Demography of @CCHS_CSIC #Madrid
#research
@ERC_Research @CCHS_CSIC What we want to do?🧐
👉🏾 reformulate and generalize standard theories of human #health and #mortality
👉🏾propose new formal models and a systematic agenda to empirically test hypotheses that link developmental #biology, #epigenetics and adult human illness, #disability mortality.
@ERC_Research @CCHS_CSIC Together with Alberto Palloni, the team is joined by demographers, geographers and technicians:

Good afternoon! I was looking into articles on hormone blockers and found this one from 2017. I’d like to talk a little bit about what it shows.
#puberty #trans #biology

ncbi.nlm.nih.gov/pmc/articles/P…
The story behind this article is that of a healthy child, born male, but demonstrating the desire to be a girl at age 3.

Her parents placed her in therapy, with the hopes of resolving dysphoria, until age 7. During that time she tried to “behave as a boy”.
At age 9, the child declares herself the female gender and at age 11, she is referred to a “gender identity program”. She has just started male puberty.

Spectroscopy allows us to spy on molecules invisible to the naked eye. Through a cuvette the spectrophotometer allows us to peer and measure concentrations with the help of Beer! 👉 bit.ly/2N4nzXE
#366DaysOfScience #biochemistry #scicomm #realtimechem
The Beer Lambert law (Beer’s law) allows you to convert between concentration (c) of a dissolved thing (solute) & absorbance of light. Don't have a lot - use a NanoDrop so the UV-Vis fun don't stop! bit.ly/beerslawexplai…
#366DaysOfScience #biochemistry #scicomm #realtimechem
Do you listen to your spectrograph peaks when they try to speak? Or just look at highest 1 & assume purification's done? Peakiest peak *might* tell concentration - but rest can reveal contamination! 👉 bit.ly/2NblGc2

We've learned more about #whalesharks in the last decade than all the preceding years combined, so by way of #DecadeinReview, here's my take on some of the key developments (a thread)
A quick squizz at #GoogleScholar shows 1,690 entries for Rhincodon typus (the scientific name of whale shark) before 2010, and 3,800 entries since. I know there's a big date bias in GS, but little doubt that it's been a huge decade for WS #science
One of the Big Things that emerged was the phenomenon of whale shark *aggregations*, or as we like to think of them, *constellations*. The biggest known to science, >400 animals at once, was described in 2011 journals.plos.org/plosone/articl…

1/ Woo! My monster paper with Matt Wilson, "Locomotor and Hippocampal Processing Converge in the Lateral Septum" was just released in @CurrentBiology!! Not only that, but I made a comic to describe my findings!! cell.com/current-biolog…
2/ We used tetrodes to record from CA1 hippocampus and dorsolateral lateral septum, an area innervated by all CA regions of the hippocampus and many regions involved in "motivational" behavior
3/ Some cells in the LS were linearly modulated by the animal's running speed (could be positively or negatively modulated!) and/or by the animal's acceleration (also could be positively or negatively modulated!)

Let's review who's really making more babies: How much sperm is released when a penis ejaculates? Sperm counts vary from about 20 million to 100 million sperm cells per *milliliter* of ejaculate. Healthy ppl produce from 1.5 ml to 5 ml of semen each time they ejaculate.
#biology
We all know the penis expects to ejaculate every time it has sex. And it can ejaculate multiple times per day with multiple partners. It can be makin' babies Every Day.
#biology #abortion
Ovaries release one (1) egg per month. That lonely egg is viable for only a few days per month. Once fertilized, the process, if uninterrupted, takes 37-42 weeks to complete. Breastfeeding can delay release of more eggs.

Born & raised in #Fanar #Lebanon, a tiny country in the middle east with a lot to offer. I always had a positive outlook on life maybe because of the culture or values🤷‍♀️.
If you don't know #Lebanon or a #lebanese then you should start mingling 🤣

I grew up surrounded by a loving, joking & tough type of family that always support each other even amidst fighting. You can imaging being 4 kids in different age groups can cause a lot of fights growing up 😂 #siblingsfight #family #VoicesIWS
@IWS_Network
I have my issues🤷‍♀️! I always wanted to prove myself & make my family proud(2nd child). A pressure that was just in my head; they were always proud of us. I wanted to grow up to be a doctor or an army officer like my dad. Let's just say I changed my mind! #VoicesIWS @IWS_Network

Hello, I am Edna Matta. I was born in #Ibague, known as #Colombia’s #CityofMusic. A beautiful place near snow-covered volcanos (Ruiz, Santa Isabel and Tolima), large expanses of paramo forest, lakes and streams where a diverse array of animal and plant species coexist
My story starts with #powerful, #strong #women in my #family. I was the third of 4 children and my mom #firstMentor had to raise us practically alone, since my father had to work in a different city, 20h away by car
My mom is a very #strong #woman that taught me #values, to #workhard and to be #self-sufficient #StrongWomen #StrongFamily

I was born and raised in the beautiful city of #Curitiba, southern #Brazil!
This region is famous for being cold and cloudy (yes it can be cold in Brazil!).
It is also famous for its very endemic and beautiful #Araucaria pine trees. #voicesIWS @IWS_Network @500womensci /1
#Actions speak louder than words! I am thankful for my parents for being who they are. Both always showed love for Nature, different interests and #curiosity! So no wonder by observing them I grew up to be a very curious girl who really loved Nature. #voicesIWS @IWS_Network /2
During High School I became fascinated by the #mendelian #genetics classes and the work of #gregormendel! I also loved studying animals, ecosystems and climate so the obvious choice for me in University (@PUCPR_oficial ) was BIOLOGY!! @IWS_Network #womeninscience #voicesIWS /3
