Welcome back to "Animal Slander," the series where we take common expressions about animals and debunk them with science. Today on the show, we tackle "birdbrained" and to "eat like a bird" with biologists Corina Newsome and Alejandro Rico-Guevara.

Happy (early) Earth Day, Short Wave listeners. We've received many questions from you about climate change, specifically what can individuals and households do to reduce their carbon footprint. So, we consulted two folks who have been thinking about this deeply and developing strategies for over a decade: Christiana Figueres and Tom Rivett-Carnac, two architects of the 2015 Paris Agreement.

Scientific models of disease don't predict the future. They're just one tool to help us all prepare for it. NPR global health correspondent Nurith Aizenman explains how scientific models of disease are built and how they're used by public health experts. We also look at one influential model forecasting when individual states might begin to reopen.

Italy is beginning its first tentative steps towards ending its lockdown. These are small steps, opening a few shops in areas where virus transmission has seen big falls. Part of the reason for this controlled strategy is that there are real concerns over a potential resurgence of the virus,

Around the world there are now hundreds of trials on drug treatments for Covid 19. Results so far are mixed, with antivirals developed for Ebola and HIV showing positive signs, but antimalarial drugs, championed by President Trump in particular have been shown to have dangerous potentially life threatening side effects.

A warning from history, more than 500 years ago suggests the western US in particular is entering an extreme drought, a ‘Megadrought’. When this last happened it led to war, depopulation and the spread of disease.

And its 10 years since the Deepwater Horizon oil spill in the Gulf of Mexico. Studies of fish in the region suggest they are still affected by oil from that spill and more recent lesser known pollution events.

If you have ever watched a spider as it works to build a web, spiralling inwards with a thread of silk, that intersects each glistening spoke with a precise touch of the foot, you will know that it is a remarkably complex behaviour. In this episode, presenter Geoff Marsh dives into the minds of spider-constructors as they build their webs.

CrowdScience listener Daan asked us to find out how spiders can build webs without ever being taught how to do it. Are they just little robots controlled entirely by their genetic instructions?

Spider silk expert Dr Beth Mortimer, describes the process of building a web in detail, while Professor Iain Couzin explains the simple modular behaviours that build up, in sequence, to create apparently complex instincts, like the huge locust swarms that are sweeping across vast areas of Africa and Arabia.

Taking us deep under the exoskeletons of invertebrates, Professor Gene Robinson reveals an animal's behaviours can be altered by their genes, and the root similarity between learning and instincts. Spiders, despite their tiny size, have fascinating behaviours. Some jumping spiders can work out the best way out of a maze, and one arachnologist reveals how some social spiders can cooperate to build communal webs and capture moths that are many times their size.

Geoff searches for the science that can reveal how instinct can create complex behaviour by setting up interviews at the homes of spider experts from around the world.

Last Tuesday, the military helped evacuate dozens of critically ill COVID-19 patients from overwhelmed hospitals in Queens. NPR's Rebecca Hersher says what happened that night shows how training for war does — and does not — prepare members of the armed services for a pandemic at home.

Bats are critically important for ecosystems around the world. But they also harbor some of the toughest known zoonotic diseases, and are the likely origin point for this coronavirus. Short Wave reporter Emily Kwong talks about leading theories on where this coronavirus came from, the work of virus hunters, and the rise of emerging zoonotic diseases.
