3 million volunteers! Congratulations, Zooniverse! Today we have reached an extraordinary milestone: 3 million volunteers contributing to people-powered research around the world. From classifying galaxies and discovering exoplanets to tracking wildlife, transcribing historical records, and supporting research in ecology, climate science, cell biology, and the humanities, our community has helped make real science possible at a scale no individual team could achieve alone.

The BIG Hedgehog Map A hub for mapping the UK’s hedgehogs, and pledging to make holes for them. Part of Hedgehog Street, a national campaign to save hedgehogs by PTES & BHPS.

Did you know that in the UK, hedgehog numbers have declined by between a third and three quarters over the last twenty years? 🤔

If you've seen one recently, log it on the Big Hedgehog Map 🦔

Inclusive Citizen Science: Hands On Experiences For Citizen Science Month, members of SEI York's Inclusive Citizen Science group have spoken about what citizen science means to them and their work. In this video, Smriti Safaya shares her…

"When we give people the opportunity not just to be in nature, but to know nature, it forges connections."

SEI York's Smriti Safaya emphasizes how getting hands on with nature offers powerful pathways to connect with our environments: buff.ly/87MVfgL

The central square (blue rectangle) represents communication in transboundary citizen science initiatives as our core study object. The outer rectangles (green for various environmental factors, yellow for socio-cultural factors and light grey for institutional background of the organising entities) refer to different contextual/background factors, which interact with how communication plays out in practice.

Humans and animals have the same taste in animal mating calls The bright colors of butterfly wings, the sweet aromas of flowers and the euphonious melodies of songbirds all evolved as signals that help individuals propagate, yet humans also find these very same signals pleasing to their own senses. In a study published today, Mar. 19, in Science, scientists from the Smithsonian Tropical Research Institute (STRI) collaborated with researchers in U.S., Canada, and New Zealand to show that humans and animals not only express the same subjective preferences for one type of signal—particular animal mating calls. In addition, across the range and complexity of the animal sounds found in nature, humans and animals show overlapping preferences for certain qualities of an animal’s call. These findings indicate that preferences for some animal sounds are more universal than previously known.
