Science: Mapping A Bat’s Navigation Neurons In 3D, Poison Dart Frogs, Fabrics

Researchers uncover how grid cells fire in a 3D space to help bats navigate, and a fabric that switches between being stiff and flexible.

In this episode:

00:47 Mapping a bat’s navigation neurons in 3D

Grid cells are neurons that regularly fire as an animal moves through space, creating a pattern of activity that aids navigation. But much of our understanding of how grid cells work has involved rats moving in a 2D plane. To figure out how the system works in a 3D space, researchers have mapped the brain activity of bats flying freely around a room.

09:59 A flexible fabric that transforms from soft to rigid (and back again)

Researchers have created a ‘tunable’ fabric, inspired by medieval chainmail, that when compressed changes from flexible to rigid. The stiffened structure can hold 30 times its own weight, and the team behind it suggest this material could be used to build temporary shelters or have medical applications.

16:33 Stark warning from the IPCC’s latest report

This week the UN’s Intergovernmental Panel on Climate Change released its long awaited report detailing compiling the latest climate science data. Nature’s Jeff Tollefson joins us to discuss the report and the warnings it contains for our warming world.

Views: Hawk-Eagles And Oriental Pied Hornbills Hunt Bats In Malaysia

Hawk-eagles and hornbills play to their unique strengths as they pluck bats mid-flight.

The oriental pied hornbill is an Indo-Malayan pied hornbill, a large canopy-dwelling bird belonging to the family Bucerotidae. Two other common names for this species are Sunda pied hornbill and Malaysian pied hornbill. The species is considered to be among the smallest and most common of the Asian hornbills.

Health & Nature: ‘How Bats Can Transmit Viruses’

When it comes to viruses jumping from animals to humans, bats hold a unique place in the transmission chain. Christopher Golden and James Longman investigate an abandoned mine for signs of poaching or viruses impacting the bat population.

Science Podcasts: Birds & Sensory Pollution, Covid-19 Vaccine And Tiny Bats

Researchers try to unpick the complex relationship between sensory pollutants and bird reproduction, and how to combat organized crime in fisheries.

In this episode:

00:46 Sensory pollution and bird reproduction

Light- and noise-pollution have been shown to affect the behaviour of birds. However, it’s been difficult to work out whether these behavioural changes have led to bird species thriving or declining. Now, researchers have assembled a massive dataset that can begin to give some answers. Research article: Senzaki et al.

Interim results from a phase III trial show compelling evidence that a coronavirus vaccine candidate can prevent COVID-19. However, amid the optimism there remain questions to be answered – we discuss these, and what the results might mean for other vaccines in development. News: What Pfizer’s landmark COVID vaccine results mean for the pandemic

25:39 Organised crime in fisheries

When you think of fishing, organised crime probably isn’t the first thing that springs to mind. However, billions of dollars every year from the fishing industry are lost to criminal enterprises. We discuss some of the impacts and what can be done about it. Research Article: Witbooi et al.

We discuss some highlights from the Nature Briefing. This time, a time-capsule discovered on the Irish coast provides a damning indictment of Arctic warming, and some human remains challenge the idea of ‘man-the-hunter’. The Guardian: Arctic time capsule from 2018 washes up in Ireland as polar ice meltsScience: Woman the hunter: Ancient Andean remains challenge old ideas of who speared big game
