Engineering Explained examines new research suggesting corn ethanol in US gasoline may emit as much or more carbon than gasoline. It covers the Renewable Fuel Standard and why ethanol was assumed to be a green fuel.

Tim Hutton's demonstration of SmoothLifeL, a continuous version of Conway's Game of Life using floating point values. It shows gliders traveling in any direction, rotating pairs, and elastic cord-like structures, with config details to run it yourself.

AVweb's Paul Bertorelli explains why general aviation has failed to replace leaded avgas, blaming industry inertia, bureaucratic delay and an exemption that removes the incentive. This is part one of two.

AVweb's Paul Bertorelli explains in part two of a series why general aviation has not replaced leaded avgas. He covers industry inertia, bureaucratic delays and the exemption that lets the industry keep using lead.

A very short microscope clip of a neutrophil chasing a Staphylococcus aureus bacterium, originally from David Rogers at Vanderbilt University. It is a widely reposted piece of immune-system footage.

A 52-minute short version of the documentary The End of Suburbia, about peak oil and the end of cheap energy. It argues that American suburbs depend on cheap oil and may become the slums of the future.

Energy scholar Vaclav Smil argues that global energy transitions are slow and that renewable targets should not rest on wishful thinking. He appraises how energy dependencies are likely to change and asks for using much less.

Destin Sandlin of Smarter Every Day gives a talk to an aerospace audience, comparing how Apollo was engineered and managed with NASA's Artemis program. He raises concerns about unresolved details, the number of launches and in-orbit fuel transfer needed to reach the Moon, and the loss of institutional knowledge.

Drew Berry shows scientifically accurate animations of molecular processes inside cells, such as DNA replication, at TEDxSydney.

Louis C.K. on Conan explains why he won't give his kids cell phones. He argues that phones keep people from sitting with sadness and being alone with their thoughts, and that kids lose empathy when they cannot see another person's reaction.

Michael Levin presents his lab's work on how cellular collectives use bioelectric networks to make anatomical decisions. Topics include pattern memories, regeneration and synthetic living organisms.

In a 2010 Google Tech Talk, Kirk Sorensen gives an economic analysis of what spent nuclear fuel actually contains. He argues it is mostly valuable material that can be partitioned and reused, not just waste to be isolated for 100,000 years.

Ron Vale of UCSF and HHMI gives an introductory lecture on kinesin, dynein and myosin motor proteins. He covers their roles in cells and how they turn ATP hydrolysis into directed motion and force.
