In the middle of the South Pacific lies Point Nemo: the most remote location on Earth. This super isolated spot is home to a graveyard filled not with human remains, but hundreds of broken up spacecraft and satellites. And after more than five decades of dumping our space junk there, some scientists have started to worry about the consequences. Correction: 1:25 Our label says "Africa," but that's actually South America. It is the South Pacific Gyre after all! Thank you to everyone who pointed this out.

Dig into the science of inhalers, and find out how these devices treat common respiratory conditions like asthma and COPD. -- Inhalers are mainly used to treat two conditions: asthma and chronic obstructive pulmonary disease, or COPD. And there are two main types: preventative inhalers and rescue inhalers. Preventative inhalers can be used every day to control symptoms, while rescue inhalers are great in an emergency. So, how do they work? Anna Rothschild explains the science behind these simple yet powerful devices. Lesson by Anna Rothschild, directed by Max Zaglotskyi, Anna Sai, Darvideo Animation Studio.

Soviet agronomist Nikolai Ivanovich Vavilov was obsessed with plants. Especially finding out where domesticated crops first came from.
