In 1960, three scientists predicted that the world would end on November 13, 2026, due to overpopulation. Here's why they were wrong.
Experts say there is a "plethora" of social media content about the hormone, which is often unhelpful in explaining why it's essential.
Clocks occasionally go backwards for a second to keep Earth time in sync with the stars. But the powers that govern time measurement are about to vote to end the practice.
Nikon disqualifies the winner of its prestigious science competition for using AI after microscopy experts questioned the accuracy of the clip on social media.
The clocks are so accurate they could run for 30 million years and only lose a second of time.
AI companies say their tools could be used to make biological weaponry. These are the threats and what can be done to mitigate them.
Stunning scenes of the world through microscopes have been put on display by the Nikon Small World In Motion competition winners.
A rare combination of tools and fossils found in a Chinese cave could help scientists learn more about our mysterious extinct cousins, the Denisovans.
Archaeologists find evidence in Indonesia of a human who appeared to use betel nut for its psychoactive properties up to 25,000 years ago.
A single flash of energy spotted by the world's most sensitive dark matter detector has scientists excited they may have found hints of the elusive substance that permeates the universe.
NASA's latest space telescope may up-end our entire model of the cosmos by taking a closer look at a shadowy phenomenon dubbed "dark energy".
NASA is due to launch its latest space telescope, a repurposed spy satellite which will accompany the James Webb Space Telescope. So what is it, and why is it being used?
Australian scientists are among the winners of a photo competition featuring stunning images of peeking damsel flies, tree selfies and cuddling manatees.
A new study suggests one of the most significant clashes in the history of the Milky Way, dubbed the "Low-energy-Kraken-Heracles" merger, happened 12 billion years ago.
The discovery of a new type of astrophysical object could take us closer to solving one of astronomy's biggest puzzles from the early universe.
Male redback spiders somersault onto the female's fangs while mating and are killed. Researchers crossbred the Aussie spiders with their NZ cousins to find out why.
The highest-resolution imagery of the Sun's surface ever taken reveals dizzying currents, and clues about our star's magnetic fields.
Neptune's strange moon and ring system has puzzled astronomers for decades, but data from the James Webb Space Telescope (JWST) might help explain how it formed.
This year, scientists included a new potential threat in their decision to move the Doomsday Clock closer to midnight. So what is 'mirror life' and why are they concerned?
Coal, oil and gas are major ingredients for far more than just energy. Why are we so reliant on oil, and how difficult would it be to find other resources?
The June solstice is the shortest day of the year in Australia, but not the one with the latest sunrise or coldest weather. Here's why.
Physicists think they have found the cellular mechanism behind a Venus flytrap's signature move, but plant scientists say the mystery isn't solved yet.
Scientists have found that mosquitoes in the lab can be trained to connect the smell of a widely used repellent with food, but repellents are still the best way to protect yourself.
Most fertiliser is a by-product of the oil industry, which is why it's so vulnerable to the blockade of the Strait of Hormuz. But there are other sources the industry could eventually switch to.
Archaeologists have found a hole in a 59,000-year-old tooth, which they say was drilled to treat a painful cavity. The find suggests Neanderthals could perform complex medical procedures.
