High-tech tags are revealing a side of the Hector’s dolphin the world rarely sees – its showstopping acrobatics beneath New Zealand’s waters. At just 1.4 meters (4.5 feet) long, Hector’s dolphins (Cephalorhynchus hectori) are the smallest marine dolphins in Earth’s seas. They are not to be confused with other record-holding small cetaceans, like the vaquita, […]

A large asteroid strike on the Moon could have negative consequences for the artificial satellites we now depend on. That being the case, a NASA-led team has looked into the options for preventing Asteroid 2024 YR4 from making such an impact in 2032. Contrary to the usual conclusions that asteroids should be diverted, not destroyed, […]

Prior to the start of the Ice Age, a period of global warming may have led to a northward shift of the monsoon rains, allowing prehistoric hominins to migrate out of Africa before crossing the Kazakh Steppe and the Hindu Kush, finally reaching northern India almost 3 million years ago. At least, that’s the theory […]

While keeping tabs on the whale sharks around the US coast, scientists came across one individual with an unusual bent back, curved like a curly S towards its tail. They believe the animal might have a form of kyphoscoliosis, making it the first whale shark with a spinal deformity ever recorded. The 6-meter (nearly 20-foot) […]

There’s a strange phenomenon reported among some recipients of organ transplants whereby people report altered memories, tastes, and personality changes.

Practice, the saying goes, makes perfect. And, if you believe a common piece of wisdom, it’s a specific amount of practice: 10,000 hours.

For some ophiophobes, even the thought of a snake is enough to set pulses racing. But while there might be something to fear from the pythons and king cobras of the world, surely most people could be persuaded to enjoy the world’s smallest snake? Meet the Barbados threadsnake.

The man who first unified China in 221 BCE was so determined to live forever that he commanded a group of alchemists to venture to a mythical mountain in search of the source of eternal youth. Evidence of this harebrained mission has now been discovered on the shore of Gyaring Lake on the Tibetan Plateau, […]

Two centuries ago, a French inventor gazed out of his window in Saint-Loup-de-Varennes and captured a defining moment in the history of science (not to mention art). As the sunlight poured down on the rooftops ahead, Nicéphore Niépce set up a peculiar contraption on his windowsill: a darkened box holding a pewter plate coated with […]

Fifteen years after launch, Japan has announced the end of the “Planet C” mission, leaving humanity with no presence around Venus.

The early stages of the mission […]

High energy scans or the body looking for tumors or infections could be greatly improved by adopting perovskite detectors instead of the fragile or low-resolution options currently in use, a new study reports. The process would not only make the diagnosis of health threats more accurate, but reduce exposure to radiation that can cause problems […]

A poem of praise for the famous sultan Salah ad-Din Yusuf ibn Ayyub (Saladin) has been misdated, a new paper argues, and refers not to an unusually close planetary conjunction but to the supernova of 1181. If the claim is correct, the poem’s words could be of scientific value to astronomers hoping to establish how […]

In the latest of many, many predictions of the end of the world, the Earth is set to end on Tuesday, September 23, 2025, according to a conspiracy theory going wild on TikTok and X.  Every now and then, someone (sometimes, but not always, Isaac Newton) suggests that the world is about to end in […]

Fast-moving objects like interstellar comet 3I/ATLAS may be planet-forming seeds, potentially helping to solve an old Solar System mystery. On July 1, 2025, astronomers spotted an object moving through the Solar System at nearly twice the velocity of previous interstellar visitors ‘Oumuamua and Comet Borisov. The object, which was confirmed to be an interstellar comet […]

Imagine yourself by a stream in Shuitangba, China, 6 million years ago. The birds are singing, the Sun is shining, and you’ve just woken up to find a wolf-sized otter sniffing your toes.
