Reminds me I must check this hive for varroa levels. And yes, we also test our lab hive with the Foster Method

The great thing about this work is Andrew’s use of ‘We’ve’. As in, the DOC rangers are doing the testing themselves as and when needed. Great effort team 👏🏻 👏🏻

If you're a fan of real-time PCR / qPCR and you've been around it a long time (yes to both) then you might also be interested in this 'dual memoir' by Russ Higuchi (inventor of qPCR) and Lincoln McBride (led the development of the instrument below - the first commercial real-time instrument)

Knowing the sex of #takahe chicks as soon as possible is important for efficient breeding management. With a new rapid #qPCR sex test developed by @dnature.bsky.social , we can now determine the sex of up to 48 chicks in less an hour in the field. A game changer! #conservation #genetics

Biologist whose innovation saved the life of British teenager wins $3m Breakthrough prize
Prof David Liu is among the winners of 2025’s ‘Oscars of science’, with honours also going to researchers for landmark work on multiple sclerosis, particle physics and ‘skinny jabs’ For the past five years, David Liu – a professor at the Broad Institute of MIT and Harvard, a biomedical research facility in Massachusetts – has marked Thanksgiving by handing over his entire annual salary, after taking care of taxes, to the staff and students in his laboratory. It started as the pandemic broke and Liu heard that students who wanted to cycle instead of taking public transport could not afford bicycles. Given how hard they worked and how little they were paid, Liu stepped in. He couldn’t unilaterally raise their incomes, so emailed them Amazon eGift cards. This ran into problems too, however. “Everyone thought they were being scammed,” he recalls. And so he switched to writing cheques. Continue reading...
