Science Podcast: How Brain Cells Use Energy, Lobster Bellies & Red Meat
Ultra-precise measurements connect brain activity and energy use in individual fruit-fly neurons.
In this episode:
00:45 How brain cells use energy
A team of researchers have looked in individual fruit-fly neurons to better understand how energy use and information processing are linked – which may have important implications for future fMRI studies in humans.
Research Article: Mann et al.
07:04 Research Highlights
A tough but flexible material inspired by lobster underbellies, and research reveals that red meat consumption hasn’t dropped since the 1960s.

Science: Salt Water Evaporation Creates “Crystal Critters’ (MIT)
A team of MIT researchers have observed that when salty water evaporates from a heated, superhydrophobic surface the crystal structures that form can easily be removed or roll away on their own.
This phenomenon could make it possible to use brackish or salty water, without any pretreatment, rather than relying on freshwater sources, for cooling systems in power plants.

Analysis: How Do Video Games, Smartphones & Computers Affect Brains
Smartphones, computers, gaming consoles or digital tablets are now givens in our daily lives. The electronic intrusion is causing controversy and collective hysteria. This documentary asks: Are we damaging our brains with all these screens? How will unprecedented exposure to screens impact humanity?
To find out, the filmmakers examine how science has been applied to distinguish between truth and falsehoods, and explore the suspected side-effects of screen exposure. The documentary travels through the US and Europe to meet and speak to researchers who are leaders in this field.

Science: Inflatable Self-Supporting Structures, River Carbon Emissions
The self-supporting structures that snap into place, and how a ban on fossil-fuel funding could entrench poverty in sub-Saharan Africa.
In this episode:
00:45 Self-supporting, foldable structures
Drawing inspiration from the art of origami, a team of researchers have demonstrated a way to design self-supporting structures that lock into place after being inflated. The team hope that this technique could be used to create arches and emergency shelters that can be quickly unfolded from flat with minimal input.

09:55 Banning fossil-fuel funding will not alleviate poverty
A ban by wealthy nations on the funding of overseas fossil-fuel projects would do little to reduce the world’s climate emissions and much to entrench poverty in sub-Saharan Africa, argues economist Vijaya Ramachandran.
