Science: Miocene Apes And Human Evolution (Video)

More than ten million years ago, the world was brimming with a wide variety of apes. Scientists studying the ones that are still alive today can learn a lot about human evolution—but they miss out on many clues that can only be found from the apes that went extinct. Watch to learn how fossil apes have strengthened ideas about how humans evolved, and what steps we can take to learn even more about our ancient ancestors. Read the review: https://scim.ag/3hw5PVx

Air Travel: The Rise Of Pilotless Planes (Video)

Over the past 100 years, the technology inside airplanes has become more and more advanced from jumbo jets to smaller Cessna’s. Some see the next step to full automation as removing the pilot completely. Reliable Robots and Xwing are two Bay Area start-ups working on doing just that. Rather than build new aircraft, both companies have retrofitted Cessna Grand Caravan’s. The planes can fly autonomously with a remote operator who monitors the flight and can take control if needed. Both companies are working with the FAA on getting approval. Xwing took CNBC for a test flight, where the pilot didn’t touch the controls once. Watch the video to learn how it works and when pilotless planes will become the norm.

Analysis: Why The World Is Running Out Of Sand

Even though sand can be found in nearly every single country on Earth, the world could soon face a shortage of this crucial, under-appreciated commodity.

Here’s what’s behind the looming sand crisis.

Analysis: The Microchip Shortage Limiting Autos

While the automotive industry was ravaged early on in the pandemic thanks to lockdown measures and a dramatic decrease in travel, it more recently has begun facing a new problem: a shortage of microchips.

Microchips are vital to much of a vehicle’s key functions, such as engine control, transmission, infotainment systems, and more. In the last half of 2020 and now in 2021, vehicle sales recovered fairly quickly, faster than automakers anticipated.

Suddenly, they were struggling to meet demand. At the same time, chipmakers were experiencing supply shortages and increased demand from other sectors, such as personal electronics. With the resulting lack of microchip supply, automakers have been forced to slow production, even on their most popular models. For several automakers, the shortage is expected to cost them $1 billion or more — and even still, the alternatives are worryingly few.
