Life doesn’t just need water and oxygen to thrive, it also needs iron.
When water and boiling oil mix, the result can be explosive, as seen in this demonstration.

Deep-fried turkeys are delicious, but making one can be dangerous. The scientific reason for fiery Thanksgiving mishaps? A difference in the densities of ice, water and oil.
Flouride is created by Wolf–Rayet stars, here seen in the Milky Way by the Hubble Space Telescope.
Tracing the cosmic origin of toothpaste, scientists got a glimpse into the surprising chemistry of early galaxies.
Our sense of touch is actually lots of different senses rolled into one.

New research suggests that fire from the sky in the form of a small asteroid annihilated a city near the Dead Sea 3,600 years ago.
Indigenous artists have been engraving rock shelters for millennia - long before the Kimberley’s celebrated rock art paintings. Now the rocks’ natural coatings are yielding clues to the engravings’ creation.
Science teaches you many skills. Even if you don’t plan for a science related career, including a science subject in your senior years can provide a good balance. But only if you’re interested.
One potential way to make opioids less addictive is to make them target injured tissue rather than the healthy brain.

While the COVID-19 pandemic raged on, the opioid epidemic got worse as drug overdose deaths soared. New research proposes a way to chemically modify opioids to reduce the risk of addiction.
Fool’s gold, or pyrite, is made of worthless iron disulfide, but can contain tiny amounts of the real thing. Using an ‘atom probe’, research has uncovered a new way gold atoms can hide in pyrite crystals.

The quasicrystals were ‘accidentally’ synthesised during the first test of a nuclear bomb in July 1945.
Nespresso machines, which brew espresso and coffee from coffee capsules, can be used for covid tests.
Wax, vials, a coffee capsule and boiling water are the main components of a brand new COVID-19 test.

Thousands of chemical compounds in wildfire smoke are interacting with each other and sunlight as the smoke travels. For people downwind, it can become more toxic over time.
Infrared sensors make it possible to measure a person’s body temperature without touching the person’s body.

Sensors are everywhere, from your phone to your medicine cabinet. Here’s how they turn events in the physical world into words and numbers.
New research suggests ordering the elements by atomic radius and ability to attract electrons.
Our research marks the first case of both normal diamonds, as well as Londaleite, being produced in a lab setting using only intense pressure.
