Science In Action

BBC World Service

The BBC brings you all the week's science news.

Listen to the last episode:

Last week, the website covid.gov looked very different, containing information on coping with covid and US research. This week it leads you to a White House webpage outlining the lab-leak hypothesis – that the pandemic was the result of dodgy lab work at the Wuhan Institute of Virology. The scientific consensus however continues to suggest a zoonotic crossover event. And a preprint recently published by Zach Hensel of ITQB NOVA (NOVA University Lisbon) and Florence Débarre of the Sorbonne, adds new early sequences to the evidence base. As they suggest, it doesn’t seal the debate, but it certainly doesn’t surprise the scientists.

As the Trump administration continues to rattle swords with US science, we speak with Lisa Fazio of Vanderbuilt University who found out abruptly her funding from the National Science Foundation is ending, and Don Ingber, founding director of Harvard University’s Wyss Institute about the impacts they are feeling from the federal belt tightening.

Finally we learn this week of an eerie species of Hawai’ian caterpillar moth. Not only is it carnivorous, but it ties small pieces of the indigestible remains of insects and bugs found in spider webs to its case, like a gruesome, camouflaged suit of armour. Why? As Dan Rubinoff of Hawai’i describes, it protects it from the hungry host spider, making it appear as the leftovers of yesterday’s dinner, or perhaps the shed exoskeleton of the spider itself.
