ελληνικά / Deutsch / Português Welcome! In this post, we’ll be taking a character-by-character look at the source code of the BioNTech/Pfizer SARS-CoV-2 mRNA vaccine. I want to thank the large cast of people who spent time previewing this article for legibility and correctness. All mistakes remain mine though, but I would love to hear about them quickly at email@example.com or @PowerDNS_Bert Now, these words may be somewhat jarring - the vaccine is a liquid that gets injected in your arm.
The idea that millions of sperm are on an Olympian race to reach the egg is yet another male fantasy of human reproduction
For almost a century, the anonymous members of Nicolas Bourbaki have written books intended as pure expressions of mathematical thought.

Držitelka Nobelovy ceny za biologii Frances Arnoldová stáhla jeden vědecký článek, u kterého je uvedena jako vedoucí autorka. Americká bioložka veřejně upozornila na chybu ve své práci a požádala o její stažení z prestižního časopisu. Jde o ukázku toho, jak bojovat s problémem zvaným replikační krize.

New maps that use information from the Copernicus Sentinel-5P satellite reveal emissions of nitrogen dioxide along a Siberian natural gas pipeline that connects the Urengoy gas field – the second-largest gas field in the world – with Europe.
Henrietta Lacks (born Loretta Pleasant; August 1, 1920 – October 4, 1951) was an African-American woman whose cancer cells are the source of the HeLa cell line, the first immortalized cell line and one of the most important cell lines in medical research. An immortalized cell line reproduces indefinitely under specific conditions, and the HeLa cell line continues to be a source of invaluable medical data to the present day.Lacks was the unwitting source of these cells from a tumor biopsied during treatment for cervical cancer at Johns Hopkins Hospital in Baltimore, Maryland, U.S., in 1951. These cells were then cultured by George Otto Gey who created the cell line known as HeLa, which is still used for medical research. As was then the practice, no consent was obtained to culture her cells, nor were she or her family compensated for their extraction or use. Lacks grew up in rural Virginia. After giving birth to two of their children, she married her cousin David "Day" Lacks. In 1941 the young family moved to Turner Station, near Dundalk, Maryland, in Baltimore County, so Day could work in Bethlehem Steel at Sparrows Point...

Objective: To find out whether taking images of the male and female genitals during coitus is feasible and to find out whether former and current ideas about the anatomy during sexual intercourse and during female sexual arousal are based on assumptions or on facts. Design: Observational study. Setting: University hospital in the Netherlands. Methods: Magnetic resonance imaging was used to study the female sexual response and the male and female genitals during coitus. Thirteen experiments were performed with eight couples and three single women. Results: The images obtained showed that during intercourse in the “missionary position” the penis has the shape of a boomerang and 1/3 of its length consists of the root of the penis. During female sexual arousal without intercourse the uterus was raised and the anterior vaginal wall lengthened. The size of the uterus did not increase during sexual arousal. Conclusion: Taking magnetic resonance images of the male and female genitals during coitus is feasible and contributes to understanding of anatomy.
