The cube shown above, known as the element cube, combines every 'collectible' element on Earth. Regarded by its creator as the world’s largest alloy, the cube is fashioned into a minimalist decorative ornament that could sit on your desk or coffee table! It consists of 62 elements (shown below) and measures 5 cm by 5 cm; it ships with a material analysis report - that presumably indicates what percentage of each metal is contained in the alloy - and offers custom engraving as an extra option.

This video explains it quite well. The key hormone in question is serotonin. Serotonin is known to play a role in depression. Low serotonin levels are believed to be the reason for depression and associated symptoms of anxiety, apathy, fear, feelings of worthlessness, insomnia and fatigue. The opposite is true when a high-level of serotonin is present, you feel jovial and enthusiastic. MDMA promotes the formation of this hormone.

When chemistry and physics come together, it looks awesome. This is the emission spectra of the Elements - in other words, these are the colors they emit in the gaseous state.

Thanks to a shipwreck in the Baltic Sea, we now know what 170-year-old champagne (kept in near perfect aging conditions) tastes like! Tasters described the aroma of the champagne - likely the oldest ever imbibed - as spicy, smoky, and leathery.

At 9% alcohol by volume, it was significantly less alcoholic than the modern version, which contains about 12% alcohol, likely due to a less efficient fermentation process. The researchers also found traces of chemicals from wood, suggesting that the champagne was fermented in barrels.

Nitrogen triiodide (NI3) is a contact explosive that sets off whether it comes in contact with a feather or a bug. As shown in the diagram, the chemical is made up of a cluster of three iodine atoms around one side of a nitrogen atom. The result of such a crowd around one atom causes something called bond strain - the atoms repel each other in a small space. The result of this bond strain is that the molecule is prone to falling apart very, causing the mini explosion you see ().

Pamukkale, meaning "cotton castle" in Turkish, is a natural water terrace site located in the Denizli Province of southwestern Turkey. The site contains several hot springs contained by stark, white limestone deposits known as travertines, that are fed by the overflowing, mineral-rich spring waters. People have been bathing here for thousands of years. ...
