How can trees help in the fight against climate change? Dig into the efforts to rebuild damaged ecosystems and reduce carbon emissions.

Uploaded 27-10-20

--

Today humanity produces more than 1,400 tons of carbon every minute. To combat climate change, we need to reduce fossil fuel emissions, and draw down excess CO2 to restore the balance of greenhouse gases. Like all plants, trees consume atmospheric carbon through photosynthesis. So what can trees do to help in this fight? Jean-François Bastin digs into the efforts to restore depleted ecosystems.

Lesson by Jean-François Bastin, directed by Lobster Studio.

Throughout history, scientists have proposed conflicting ideas on how the brain carries out functions like perception, memory, and movement. Is each of these tasks carried out by a specific area of the brain? Or do multiple areas work together to accomplish them? Ted Altschuler investigates both sides of the debate.

Our eyes are practically magical, but they cannot see everything. For instance, the naked eye cannot see the moment where all four of a horse's legs are in the air or the gradual life cycle of plants -- but cameras can capture these moments. Bill Shribman gives examples where photography can pick up where the eye leaves off.

Explore the differences between how a car’s internal combustion engine and an electric vehicle’s induction motor use fuel.

In 2015, two men drove a Volkswagen across the US on just over 100 gallons of fuel. Their 81-mile-per-gallon performance doubled the car’s estimated fuel rating, and set the record for the lowest fuel consumption ride of a diesel car. The duo were experts in techniques that maximize fuel efficiency. So, how did their strategy save fuel? Shannon Odell explores what’s going on beneath a car’s hood.

The vast majority of people who’ve lost a limb can still feel it — not as a memory or vague shape, but in complete lifelike detail. They can flex their phantom fingers and sometimes even feel the chafe of a watch band or the throb of an ingrown toenail. What causes these phantom limb sensations? Joshua W. Pate explains how the brain reacts to a missing limb.

Dig into the 1947 Partition of India, when Britain split the region into two states, India and Pakistan, and the mass migrations and violence that followed.

Uploaded 21-06-21

--

In 1947, the British viceroy announced that after 200 years of British rule, India would gain independence and be partitioned into Hindu India and Muslim Pakistan. What followed was one of the largest and bloodiest forced migrations in history: an estimated 1 million people lost their lives. What caused this violent aftermath? Haimanti Roy details the lasting legacies of the Partition of India.

Lesson by Haimanti Roy, directed by Jagriti Khirwar and Raghav Arumugam.

Right now, invisible signals are flying through the air all around you. Massive radio waves carry information between computers, GPS systems, cell phones, and more. And the sky is flooded with interference from routers, satellites, and, of course, people flying who haven’t put their phones on airplane mode. So, what exactly does airplane mode do? Lindsay DeMarchi explains the setting's importance.
