Antibodies are the secreted form of B-lymphocyte receptors and are a part of adaptive immunity, but how are these proteins formed?
Above is a diagram illustrating Paul Ehlrich’s Side Chain Theory of Antibody Formation. Ehlrich proposed that immunoglobulin molecules, a fundamental component of adaptive immunity, served as membrane bound proteins that bound to particular threats, similarly to the former “key in lock” view of enzymes in catalyzing biological reactions. Ehrlich also suggested that the action of binding a pathogenic molecule to the receptor would generate a signal to stimulate the production of more receptors of the same specificity. These “side chains” that were added on would then break off from the cell surface and become what we call antibodies.
We now know, however, that soluble immunoglobulin receptors are specially manufactured to be secreted as antibody, rather than just “breaking off” of the lymphocyte, even though they have the same specificity as their membrane-bound counterparts.

The astro-fashion-loving Internet collectively gasped when ESA’s Hubble twitter account posted three gorgeous gowns, by Czech designer Jirina Tauchmanova with only credit “Photo: Vasek”, which google thinks is a Canadian tennis player. For four long days I couldn’t find anymore images, until, today! Which is why I’m sharing a belated #FashionFriday and #StarrySunday combo.
These gown were shown at Serbia Fashion Week back in December 2015 as Jirina Tauchmanova‘s Spring/Summer 2016 collection – I hope that means they will be available for purchase soon!
I think I recognize at least two of the images, NGC 602 & 30 Doradus, but I’m going to have to see these in person to be sure, yes, definitely, and probably try them on, too.

Yes! It’s not ~very~ legal, but I think this is very important to know if you gonna do research.
I also read somewhere saying that if you have this kind of issue and you aren’t really in a rush, you could reach out to the people that did the research and ask them for the article! We all have the same problem with publication sites and most people just want their research to be known and cited. They would love to help you too, we’re all scientists after all. I, personally, haven’t tried this yet since I’m currently not doing any research, so I’m not 100% sure about the success probability. But hey, it worth a shot I have to say.
I havent seen anyone talk about this yet so im making a post.
So lets say you’re researching something for a paper (or just for fun) and the research paper you want to read is behind a paywall, or the site makes you create an account first, or makes you pay to download, or limits you to only 5 free articles, or otherwise makes it difficult for you to read what you want.
do not fear! copy the link to the article
go to sci-hub.se (the url is always changing so its best to check out whereisscihub.now.sh to find what the current url is)
slap the article link in there
A site of intense star formation, the Carina Nebula complex is home to some of the brightest and most massive stars in our Galaxy, the Milky Way.
This immense nebula contains a dozen or more brilliant stars that are estimated to be at least 50 to 100 times the mass of our Sun. The most rich and extensive one is the variable star Eta Carinae.
The visible-light view comes from the MPG/ESO 2.2-metre telescope at the La Silla Observatory and the infrared picture comes from the HAWK-I camera on ESO’s Very Large Telescope.
