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 heat and pressure generated by a nuclear explosion can produce unusual chemical curiosities.

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.
What happens to millions of these?
Batteries power much of modern life, from electric and hybrid cars to computers, medical devices and cellphones. But unless they’re made easier and cheaper to recycle, a battery waste crisis looms.
Light is key to ultrasensitive chemical sensors.

An optical sensor that can detect individual molecules promises early detection of diseases and environmental contamination.
Ammonium nitrate in granular form is the basis for many nitrogen fertilisers.
What do ammonium nitrate and iodine have in common? Both substances are of immense service to humankind, and the history of their discovery is closely linked to that of the production of explosives.
Jennifer Doudna and Emmanuelle Charpentier have been awarded the Nobel prize in Chemistry for their revolutionary work on ‘gene scissors’ that can edit DNA.

Breathing pure oxygen would be like fireworks exploding in your body. And that’s not always a good thing.
You might think the more oxygen you breathe in the better. But too much oxygen can make you sick.
