Mathematicians have devised a new way to solve higher-order polynomial equations, ushering in a 'dramatic revision of a basic chapter in algebra'.

Researchers have found a candidate for the hypothetical Planet Nine, which could be an undiscovered giant planet way out in our solar system. However, as with all ninth planet research, the new findings were met with some skepticism.

A new study links the Egyptian goddess Nut with the Milky Way galaxy.

Newly published images suggest that an unknown structure is trailing behind the Kosmos 482 probe on its descent to Earth. It could be the doomed craft's parachute.

Cuttlefish flash patterns and colors on their skin to communicate, and they may wave their tentacles to send visual and vibrational signals, scientists hypothesize.

A recent update caused ChatGPT to turn into a sycophant, with the chatbot excessively complimenting and flattering its users with reassurances — even when they said they'd harmed animals or stopped taking their medication. OpenAI has now reversed the changes.

Vesta, thought to be the second-largest asteroid in the solar system, could be a piece of an ancient, unknown planet, a new study hints.
