One study reports that 59% of men and 66% of women have ended a budding relationship after a bad first kiss.
An explosion at a port rocked the Lebanese capital city of Beirut on Tuesday, killing at least dozens of people. As videos of the explosion spread across social-media sites, some observers likened the appearance of a mushroom cloud to that of an atomic bomb. The Lebanese prime minister has said […]
Although it’s impossible to say exactly what would happen if all insects on Earth suddenly vanished, it’s likely that civilisation and ecosystems would be in serious trouble. Nitrogen-rich faeces would potentially build up, choking plant life and preventing new growth. Meanwhile, no dermestid beetles and other corpse-eaters would lead to […]
Bright blue fireworks are far more challenging to produce than common colours like red, white, or green. Pyrotechnicians have been trying to produce brilliant blue fireworks for centuries, to no avail. The challenge is that the copper compound needed to create that bright colour breaks down at the high temperatures […]
A New York City jury awarded 21-year-old Alonzo Yanes nearly $US60 million on Monday after he was left permanently disfigured by a botched high school chemistry experiment. Yanes was 16 years old in January 2014 when his teacher, Anna Poole, conducted an experiment that went horribly wrong, causing a fireball […]
Earth has some pretty severe weather– hurricanes,earthquakes, and tsunamis can be devastating – but we’re better off living here than on other planets. Earth’s worst storms are nothing compared to the sulfuric acid rain on Venus, towering dust devils on Mars, or supersonic winds on Neptune. Watch the video above […]
Inhaling helium and talking like Daffy Duck is a classic party trick. But not many know how helium works. Helium is much lighter than air, so sound waves move much faster through the gas. This amplifies the higher frequencies in your voice. The gas sulphur hexafluoride works in the opposite […]
Two chemists have found a way to make sunscreen work better. The treatment boosts the body’s ability to deflect ultraviolet rays which cause sunburns and cellular DNA damage. The molecule created is a simplified version of melanin, a biological pigment that can absorb and dissipate UV light, with customisable properties […]
The colours in 4th of July fireworks are made possible by combinations of different elements, from common metals to rarer minerals and even some salts. Blue is still one of the most difficult colours for firework makers to get right, since it’s made from copper, and is very temperature-sensitive. Visit […]
Enceladus, an ice-encrusted moon of Saturn, hides an ocean of saltwater that blasts ice into space. NASA flew its Cassini spacecraft through the ice geysers in 2015. Scientists continue to analyse the data, and on Wednesday a group announced that it had detected complex organic molecules. Though not definitive proof […]
People often have strong opinions about how they drink their soda. Some people prefer it in a can, others prefer a glass or plastic bottle. While soda companies claim that the recipe doesn’t change, there are a few factors that might affect the way you taste a soda depending on […]
Water – the biggest ingredient in coffee by weight – can make or break the flavour of a freshly brewed cup, according to a chemist-barista research team. Tap water brings out better flavour in coffee, though there are trade-offs between hard and soft water. Some beans are better suited to […]

The fireworks you enjoy every 4th of July are the result of a chain of chemical reactions. When a firework container is lit, its contents of coloured explosives called “stars” light up the sky. The colours that sparkle in the sky are chemical reactions happening right before your eyes. The […]
