@MissBird90 I've been wanting to do this for ages, but if it's fresh blood, I'm only ever allowed to poke myself, never the students. Where did you get the antigens? #Jealous

We enjoyed our extracurricular this lunch working out which sixth formers I can hit up for a blood donation should I need one.

Science teachers. Some basic graphs tips, maybe useful for Year 7?

Scientists have uncovered how a protein named IRF1 supports the reprogramming of #macrophages to tune the innate immune response, which could inform efforts to predict or alter the functions of these immune cells. @scisignal scim.ag/4jiBRBH

Really proud of my Y12 for their beautiful results from our practical yesterday. They learnt how to prepare slides of garlic roots. We found so many phases in anaphase! #Microscopy #Biology

@STEMyBanda @MissRimmer78 Didn't time it. Maybe 5-10 minutes? They brought them to check before adding the stain. Some areas should look translucent rather than white. One does need to accept that only about 1/3 will find anything, which is why everyone makes a slide, but they observe in teams.

@MissRimmer78 @KJF239 It's also easier if your microscopes have knobs to move the stage. Then they can do a quick sweep left to right through the whole sample and only magnify sections where the cells are not clumped to look in detail

@KJF239 @MissRimmer78 1M hot HCl for 5+ minutes. Then place on slide and use 2 dissection needles to unfurl. Literally sing to the students like Dory 🎶Just keep unfurling, just keep unfurling, keep unfurling, unfurling, unfurling🎶. If it still looks white and not transparent, keep doing it.

@MissRimmer78 That's at 1000x magnification. You can see them with 400x, but they're a bit small, so harder to identify. Core thing is to keep unfurling the root for a loooong time. Otherwise, there are too many layers of cells for them to see anything.

How to motivate Y12 to really make an effort retrieving everything they know about mitosis? With mitosis cookies, of course! Can't eat them unless I'm satisfied that all the info is there! @chatbiology @Bakerlogy

Last Sunday, @AsimovPress published an article explaining why it's so hard to diagnose tuberculosis. Here are 10 interesting things we learned about TB while editing it: 1. TB (not malaria) is the deadliest infectious disease. It kills >1.2M people each year.

@chatbiology In A-level, yes. With other years, we take other opportunities to discuss this. For example, in Y7 for how science works, we include a lesson called "black scientists matter".
