Earlier this last year, Bédécarrats and his colleagues’ published study show that injecting RNA (like DNA, but less stable) between sea slugs (Aplysia) that changed neuronal responses. The response was originally only seen in the donor after training. This change in cellular response (more sensitive to stimulation) is a form of cellular memory, but media […]
Many biology classes mention Luigi Galvani’s experiment from 1781 where he electrically stimulated an amputated frog leg, which made the leg twitch. This was revolutionary because it linked electricity to movements and life. What they don’t tell you in these classes is that: During this time, many scientists believed that a psychic fluid in our […]
Can we take a moment to appreciate how we’re bipedal (walking on two legs), because walking is really really hard. It takes us months and months to even waddle! Yet this is easy for other animals; a duckling waddles after a day. And four-legged animals can continue to walk (and trot!) after a complete spinal […]
I’ve been painting eyes in the style of other artists with unique styles that I really like: @nogobed @amdebrincat and @ellysmallwood (these are all instagram handles) Eyes are similar across many organisms and the receptors that convert light information to signals (opsins) for the cell to use is similar across all organisms. What this means […]
