5:49 PM | Botox makes unnerving journey into our nervous system
New research might bring a frown to even the most heavily botoxed faces, with scientists finding how some of the potent toxin used for cosmetic surgery escapes into the central nervous system. Researchers have shown how Botox – also known as Botulinum neurotoxin serotype A – is transported via our nerves back to the central nervous […]

11:20 PM | Introducing Lassa-VSV, a hybrid virus that kills brain tumours
Last month, I wrote about using Salmonella to deliver anti-cancer compounds to tumours. Today, I’m sharing with you a paper on cancer-fighting viruses. Why the recent focus on microbiology and cancer? Because they’re much more interconnected than you would think and because they’re both so cool! (And maybe also because I’m a microbiologist and my […]

6:14 PM | Kids with ADHD must squirm to learn
For decades, frustrated parents and teachers have barked at fidgety children with ADHD to “Sit still and concentrate!” But new research shows that if you want ADHD kids to learn, you have to let them squirm. The foot-tapping, leg-swinging and chair-scooting movements of children with attention-deficit/hyperactivity disorder are actually vital to how they remember information and […]

Weasels! by animalwondersmontana: Jessi tackles weasels! Not literally. So what is the difference between a ferret and a weasel? What about mink, fishers, stoats, and polecats? And how does the classification of wild species help pet owners? If you like this video give a mental thanks to the awesome person that sponsored this video’s topic. I’m not sure I would have done an episode on weasels if they hadn’t suggested it since we don’t have any at Animal Wonders. So […]
