Why Do Some People Tolerate Spicy Food? [Science Video]

Some people can eat raw jalapeños like they’re apples. Why do some people have a high tolerance for spicy food while others can’t stand it? SciShow explores the science of spicy food tolerance. [SciShow]

Slo-Mo Footage of a Bumble Bee Pollinating Flowers [Video]

This is beautiful. Buzz pollination is a special technique for dislodging pollen from certain types of plants – and bumble bees are among the few species of bee capable of doing it. [Smithsonian Channel | Via Nerdist]

Gravitational Waves Explained For The Layman [Video]

In September 2015, scientists witnessed something never seen before: two black holes colliding. Both about 30 times as big as our Sun, they had been orbiting each other for millions of years. A fraction of a second before the crash, they sent a vibration across the universe at the speed of light that was picked […]

Bell’s Theorem: The Quantum Venn Diagram Paradox [Science Video]

This video is about Bell’s Theorem, one of the most fascinating results in 20th century physics. Even though Albert Einstein (together with collaborators in the EPR Paradox paper) wanted to show that quantum mechanics must be incomplete because it was nonlocal (he didn’t like “spooky action at a distance”), John Bell managed to prove that […]

FIRE IN FREEFALL – Rare Physics Experiment [Video]

A slow-motion fire experiment in microgravity done by dropping a box with a GoPro and candle inside. This simulates how fire burns in space, just like the fire experiment they do on the ISS. [Physics Girl]

Warp Speed Comparison: From Warp 1 to Warp 9.985 [Video]

Ever wonder how fast the ships in Star Trek actually are? How about relative to one another? This video by Youtuber EC Henry takes a look at those differences! [EC Henry]

A Refrigerator That Cools Itself Using Stretched Rubber Bands [Video]

Let’s say that one day the whole world goes bonkers and you end up living in a post-apocalyptic society, this video by Youtuber Applied Science could help you create a refrigerator that cools itself using rubber bands. The design still needs to be perfected, but it does work, even if it just cools the inside […]

Kid Clothes Could Grow With Them

A new design could make kids clothes that fit the same child from three months to three years old. Ryan Yasin has won the James Dyson award for his work on the Petit Pli clothing range. Yasin aimed to overcome one of the most frustrating problems for parents: the way very young children outgrow clothes […]

Nanomachines That Drill Through Cancer Cells to Kill Them [Video]

Researchers at Rice, Durham (U.K.) and North Carolina State universities demonstrated in lab tests how rotors in single-molecule nanomachines can be activated by ultraviolet light to spin at 2 to 3 million rotations per second and open membranes in cells. The researchers used motors based on work by Nobel laureate Bernard Feringa, who won the […]

Mouse Brain Cells Could Act As Airport Security

Mice neurons rather than silicon circuit boards could be the key to an airport security computers according to one start-up. The Koniku Kore device is designed to sniff out explosives in the same way as a mammal. The device is the work of Nigeria’s Oshi Agabi and is based around the idea that traditional computers […]

The Amazing Ways Plants Defend Themselves

Plants are constantly under attack. They face threats ranging from microscopic fungi to small herbivores like caterpillars, up to large herbivores like elephants. But plants are ready, with a whole series of internal and external defenses that make them a less appealing meal — or even a deadly one. Valentin Hammoudi explains some of the […]
