i also really like the fact that wei wuxian is both book-smart and street smart because usually authors tend to show one trait heavier than the other (which is fair) but i like how mxtx never shied away from showing how intelligent, ingenious and and aware a person wei wuxian is. like he canonically wrote a dissertation (which we can reliably believe to not be his only one) but he’s also extremely good at navigating investigations, knowing the climate of a locality based on the people, knowing how to be smart with words to get what he wants. and this kind of thing can get annoying sometimes if the writing doesn’t handle it well but it never feels forced with wei wuxian because his in-universe charisma is transcendental, jumping right off the page and making you believe that yeah, of course this guy is just that smart!

ELISA: A Powerful Tool for Detecting the Invisible

ELISA, or Enzyme-Linked Immunosorbent Assay, has become a cornerstone of medical diagnostics and biological research. This versatile technique allows scientists to detect and quantify minute amounts of target molecules, such as proteins, antibodies, and even viruses, with remarkable accuracy. In this blog, we'll delve into the world of ELISA, exploring its various types, its applications, and the exciting future directions this technology holds.

At its core, ELISA relies on the exquisite specificity of antibodies. Antibodies are highly specialized proteins produced by the immune system in response to foreign invaders. Each antibody can bind to a unique structure, called an antigen, on a specific molecule. In an ELISA, scientists leverage this binding property to create a sensitive detection system.

The 1960s witnessed a surge in interest in immunoassays, techniques that utilize the specificity of antibodies to detect target molecules. One such technique, radioimmunoassay (RIA), developed by Rosalyn Yalow and Solomon Berson, revolutionized medical diagnostics. RIA used radioactively labeled antibodies to detect antigens, offering high sensitivity. However, concerns regarding the safety of radioactive materials fueled the search for a safer alternative. The year 1971 marked a turning point. Independently, Eva Engvall and Peter Perlmann published their work on a novel technique – the enzyme-linked immunosorbent assay (ELISA). ELISA replaced radioactive labels with enzymes, eliminating the safety concerns associated with RIA. Like RIA, ELISA harnessed the specific binding between antibodies and antigens. However, it employed enzymes that could generate a detectable signal, such as a color change, upon interacting with a substrate. This innovation paved the way for a safer and more user-friendly diagnostic tool.

The basic ELISA protocol involves immobilizing the target antigen on a solid surface like a plate well. Then, a sample containing the molecule of interest (e.g., a suspected virus) is introduced. If the target molecule is present, it will bind to the immobilized antigen. Next, an antibody specific to the target molecule, linked to an enzyme, is introduced. This "detection antibody" binds to the target molecule already attached to the antigen. Finally, a substrate specific to the enzyme is added. This antigen-antibody binding is visualized using an enzyme linked to a reporter molecule. When the enzyme encounters its substrate, a detectable signal is produced, such as a color change or luminescence. The intensity of this signal is directly proportional to the amount of antigen present in the sample, allowing for quantification. The beauty of ELISA lies in its adaptability. Several variations exist, each tailored for specific detection needs.

The Four Main ELISA Formats are:

Direct ELISA: Simplicity at its finest. In this format, the antigen is directly coated onto the ELISA plate. A labeled antibody specific to the antigen is then introduced, binding directly to its target. After washing away unbound molecules, the enzyme linked to the antibody generates a signal upon addition of the substrate. Direct ELISA offers a rapid and straightforward approach, but sensitivity can be lower compared to other formats due to the lack of amplification.

Indirect ELISA: Unveiling the Power of Amplification. Similar to the direct ELISA, the antigen is first coated onto the plate. However, instead of a labeled primary antibody, an unlabeled one specific to the antigen is used. This is followed by the introduction of a labeled secondary antibody that recognizes the species (e.g., mouse, rabbit) of the primary antibody. This two-step approach acts as an amplification strategy, significantly enhancing the signal compared to the direct ELISA. However, the presence of an extra incubation step and the potential for cross-reactivity with the secondary antibody add complexity.

Sandwich ELISA: Capturing the Antigen Between Two Antibodies. Here, the capture antibody, specific for one region of the antigen, is pre-coated onto the ELISA plate. The sample containing the antigen is then introduced, allowing it to be "sandwiched" between the capture antibody and a detection antibody specific for a different region of the same antigen. A labeled secondary antibody or a labeled detection antibody itself can then be used to generate the signal. Sandwich ELISA boasts high sensitivity due to the double-antibody recognition and is often the preferred format for quantifying analytes.

Competitive ELISA: A Race for Binding Sites. In this format, the antigen competes with a labeled antigen (usually a known amount) for binding sites on a capture antibody pre-coated onto the plate. The more antigen present in the sample, the less labeled antigen can bind to the capture antibody. Following a washing step, the amount of bound labeled antigen is measured, providing an inverse relationship between the signal and the concentration of antigen in the sample. Competitive ELISA is particularly useful for studying small molecules that may be difficult to directly conjugate to an enzyme.

ELISA's Reach: From Diagnostics to Research. The applications of ELISA are as vast as they are impressive. Let's delve into some key areas where ELISA plays a vital role:

Unveiling the Mysteries of Disease: Diagnostics: ELISA is a cornerstone of diagnosing infectious diseases like HIV, Hepatitis, and Lyme disease. It detects antibodies produced by the body in response to the invading pathogen, providing valuable information for early detection and treatment. Monitoring Autoimmune Diseases: ELISA helps monitor autoimmune diseases like rheumatoid arthritis and lupus by measuring specific antibodies associated with these conditions. Cancer Screening: Certain cancers can be detected by identifying tumor markers, proteins elevated in the blood of cancer patients. ELISA assays are being developed to detect these markers for early cancer screening.

Safeguarding Food Quality: Allergen Detection: Food allergies can be life-threatening. ELISA ensures food safety by enabling the detection of allergens like peanuts, gluten, and milk in food products, protecting consumers with allergies. Monitoring Foodborne Pathogens: ELISA can identify harmful bacteria, viruses, and toxins in food, preventing outbreaks of foodborne illnesses.

Environmental Monitoring: Pollutant Detection: ELISA can detect pollutants like pesticides and herbicides in water and soil samples, contributing to environmental protection efforts. Microbial Analysis: This technique can be used to identify and quantify specific microbes in environmental samples, providing insights into ecosystem health.

Research and Development: ELISA plays a crucial role in various research fields: Drug Discovery: It helps researchers assess the effectiveness of new drugs by measuring drug-target interactions and monitoring drug levels in the body. Vaccine Development: ELISA is instrumental in developing vaccines by evaluating immune responses to vaccine candidates. Basic Research: Scientists use ELISA to study various biological processes by detecting and quantifying specific molecules involved in these processes.

Despite its established role, ELISA is evolving alongside technological advancements. New multiplex platforms allow for the simultaneous detection of various targets in a single sample, boosting efficiency in biomarker discovery and disease analysis. Automation streamlines workflows minimizes errors, and increases throughput, making high-throughput screening feasible in drug development and clinical settings. Miniaturization and portable devices enable rapid on-site diagnostics, providing healthcare professionals with real-time data for quicker interventions. Additionally, ongoing research is improving assay sensitivity, reducing background noise, and expanding detection limits, allowing for the identification of trace analytes and early disease biomarkers with greater accuracy than ever before. Integration of ELISA with emerging technologies such as microfluidics, nanotechnology, and artificial intelligence holds promise for enhancing assay performance, scalability, and data analysis capabilities.

These advancements hold promise for even wider applications of ELISA in the future. ELISA has revolutionized our ability to detect and quantify biological molecules. Its versatility, accuracy, and adaptability make it an invaluable tool across various scientific disciplines. As research continues to refine and innovate ELISA techniques, we can expect even more exciting possibilities to emerge in the years to come. ELISA's future is bright, promising to play a pivotal role in unraveling the mysteries of the biological world and improving human health.

Eventually Candace meets/is cornered by Nick Fury, as Marvel heroes often are, and her thought process during the conversation gradually shifts from "Oh god I'm so getting vivisected" to "I can't tell if this is an interrogation or a job interview and I don't know which would be worse" to "You know what? Fuck this guy! He's more of a paranoid control freak than me at my worst!"

So obviously she won't be collaborating with SHIELD very much.

I was thinking about Dilton’s insane garage laboratory again, and I got an idea for a comic. I would draw it, but I draw so slowly that it would take forever to finish a 6+ page comic, and I have too many other ideas to work on. So all you get is a written summary:

— Dilton’s dad hears from the other parents (or the newspaper) that multiple cars have been broken into or stolen in the past few weeks, and he decides the family needs to keep their car safely in the garage instead of the driveway, at least until the perpetrator is caught.

— He informs Dilton that this means Dilt needs to clear all his science stuff out of the garage to make room for the car.

— “You want me to dismantle my lab? Dad, please, don’t do this to me! Anything else!”

— “This isn’t a punishment, it’s just how things have to be for the foreseeable future. Your lab was our garage first, and we need a garage more than we need a lab right now.”

— “But how can you expect me to transport all of my equipment within the day? Where can I possibly store it all? How can I continue my experiments under these conditions?”

— “Why don’t you ask those friends of yours for help? I’m sure they’d be more than happy to lend a hand. That boy Moose, especially, should be useful in carrying your computers around.”

— So Dilton asks the gang for help, and they agree to help him clear out his lab, as well as each taking a portion of his science stuff to look after (there wasn’t enough space in Dilton’s room for all of it). They also agree to keep Dilton’s experiments going themselves, in small ways like taking notes on observations, or adding three drops of such and such to this concoction each day… etc. They’re all excited, thinking it’s going to be fun to try their hand at mad science for a while.

— Next comes a series of little Disasters caused by Dilton’s science in the hands of his inexperienced friends over the next few days.

— One of his friends ends up drinking some sort of potion (or multiple), either on accident or on purpose, and there’s some kind of weird effect—I’m not sure what yet, but almost definitely a minor transformation of some sort, on the same level as turning green or growing a tail or only talking in parrot squawks. This causes humorous problems in their life. (Jug wouldn’t drink unknown potions on purpose, because he has common sense, but Archie has none, so it would make more sense for him to do it intentionally.)

— One of his friends has to look after some animal test subjects, like mice in cages or something, but it turns out the animals have been made superintelligent, and they break out and start sabotaging the character with clever plots. The character fights back, mostly unsuccessfully, and things descend into Tom & Jerry territory. (I think this would be funny with Jug, especially since Hot Dog could be there too, animal vs animals.)

— One of his friends (maybe Betty?) has to look after a robot, and all seems cool and fine until it malfunctions (not her fault) and turns evil or chaotic and starts destroying things. (Its glowing eyes turn from green to red, so it’s clear that it’s evil now. This was an intentional design choice on Dilton’s part, as a warning sign in case of malfunction, and because it looks cool.)

— Veronica is given something she doesn’t need to observe or use, just store somewhere and not mess with. But at a fancy party, she tries to show off to her rich friends that she’s smart as well as beautiful and wealthy by showing off ”””her””” cool new invention, and she turns it on. She immediately loses control of it, whatever it does, and it causes a Disaster. This one’s working correctly, but Veronica doesn’t understand how it works or how it turns off, so it’s still causing a problem. (Hmm… maybe a weather-creating machine? Imagine a blizzard packed into a ballroom.)

— (Midge and Moose also helped Dilton, so I need to think of two more disasters. Or maybe, since they’re closer friends to Dilton, they know a thing or two about science and following instructions, so they don’t do anything they’re not supposed to, and they happen not to meet with any malfunction-type accidents. Everything goes fine with them.)

— The comic ends with Dilton’s dad reading in the newspaper that the crook who was breaking into and stealing all these cars has been caught and put in jail. He says to Dilton that this means their car is safe (because problems are very simple in this world), and so Dilton can have the garage back for his lab. (Let’s say it’s been like a week since the start of the comic.) Dilton is excited, and says he’ll go find his friends right away and tell them, and get his science stuff back. He rushes out the front door, only to find all his friends running up his sidewalk together, all carrying the science stuff he gave them and begging him to please take it all back! (Dilton is surprised, because he had no clue about all their problems, but everybody else looks like a wreck from their individual ordeals. This is all in stark contrast to how excited they seemed in the beginning to take on the science.)

— The end! That last scene was the punchline and final panel.

life in advance wars land really is brutal. i guess that's why it's called fucking "wars world" but you really just have random enemy troops showing up in the middle of your country without your military leaders even noticing. or hell, allied troops, and they get into a skirmish with your guys ANYWAY because your leaders are being fucking stupid. millions have perished. you get drafted and join the army. your CO radios his general asking her what an airport is. he takes you guys out for a pizza party after capturing the enemy's weapons dev lab.

More work done on that photo edit from last night! Also I might have come up with a new project idea that isn't "redo Flick since no one talked me out of it" >.> Idk, though, we'll see. It'll depend on how I feel about trying my hand at fashion design.

I'll give you a hint: I need my own cloak :3

Anyway, original of this edit is under the cut as per the usual

Me, thinking about the timeline in which Doc actually picks up Clara from the train station and they fall in love then and there at first sight instead of after saving her, they probably have a long chat about how she loves to teach the sciences, etc., and she has to watch Doc get shot at the festival and then die over the course of two very long, agonisingly slow days—
