Science: Research Paper Translation, Sustainable EV’s & Giant Centipedes

A team is creating bespoke words for scientific terms in African languages, and the sustainability of the electric car boom.

00:46 Creating new words for scientific terms

Many words that are common to science have never been written in some African languages, or speakers struggle to agree what the right term is. Now a new project aims to change that, by translating 180 research papers into six languages spoken by millions of people across the continent of Africa.

13:58 How sustainable is the electric car boom?

As electric cars become more ubiquitous, manufacturers will have to up the production of batteries needed to power them. But that begs the question – can they be mass produced in a sustainable way?

We discuss some highlights from the Nature Briefing. This time, how a tusk-based ‘chemical GPS’ revealed details of a mammoth’s enormous journeys , and why the Perseverance rover’s first efforts to collect a Mars rock sample didn’t go according to plan.

Science: Vitamin D Trial In Asthmatic Children, Risks to Machine Learning

Charles Piller, an investigative journalist for Science, talks with host Sarah Crespi about a risky trial of vitamin D in asthmatic children that has caused a lot of concern among ethicists.

They also discuss how the vitamin D trial connects with a possibly dangerous push to compare new treatments with placebos instead of standard-of-care treatments in clinical trials.

Next, Birhanu Eshete, professor of computer and information science at the University of Michigan, Dearborn, talks with producer Joel Goldberg about the risks of exposing machine learning algorithms online—risks such as the reverse engineering of training data to access proprietary information or even patient data.

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.

Homes & History: ‘Down House’ – Charles Darwin’s Home In Kent, England

Down House (confusingly, next to Downe village) was Darwin’s family home for nearly 40 years. In its rooms, gardens and grounds, he researched and refined the ideas for which he became famous. 

John Goodall, August 8, 2021

In origin, Down House was a plain Georgian property, a brick box with a main front five window bays wide built in about 1730. It was internally reconfigured and extended with a kitchen block by a wealthy businessman and landowner, George Butler, after he purchased the house in 1778.

At the same time, the main entrance was moved from the front to the side of the building. The house was then leased and sold again before coming into the possession of the Revd J. Drummond, vicar of Downe, in 1837. He employed the London-based architect Edward Cresy to make various improvements and also to render the house in conformity with the taste of the moment.

It was this house, with its 18 acres of land, that the Darwins occupied on September 24, 1842. Charles quickly settled into his new home, establishing a regular routine that distinguished his domestic arrangements. ‘My life goes on as clockwork,’ he wrote in 1843, ‘I am fixed in the place where I shall end it.’
