US scientist John Hopfield and British-Canadian colleague Geoffrey Hinton won the 2024 Nobel Prize in Physics for discoveries and inventions that laid the foundation for machine learning, the award-giving body said on Tuesday.

The award comes with a prize sum of 11 million Swedish crowns ($1.1 million), which is shared between the winners if there are several. The physics prize is awarded by the Royal Swedish Academy of Sciences.

"This year's two Nobel Laureates in physics have used tools from physics to develop methods that are the foundation of today's powerful machine learning," the award-giving body said in a statement.

"Machine learning based on artificial neural networks is currently revolutionizing science, engineering and daily life." Widely considered the most prestigious prize for physicists across the world, it was created, along with awards for achievements in science, literature and peace, in the will of Alfred Nobel.

The prizes have been awarded with a few interruptions since 1901, though the Nobel economics honor is a later addition in memory of the Swedish businessman and philanthropist, who had made a fortune from his invention of dynamite.

Outside the sometimes controversial choices for peace and literature, physics often makes the biggest splash among the prizes, with the list of past winners featuring scientific superstars such as Albert Einstein, Niels Bohr and Enrico Fermi.

Last year's physics prize was awarded to Pierre Agostini, Ferenc Krausz and Anne L'Huillier for their work in creating ultra-short pulses of light that can give a snapshot of changes within atoms, potentially improving the detection of diseases.

Physics is the second Nobel to be awarded this week, after US scientists Victor Ambros and Gary Ruvkun won the medicine prize for their discovery of microRNA and its role in gene regulation, shedding light on how cells specialize.

An "amphibious mouse" with partially webbed feet that eats aquatic insects was among 27 new species discovered during a 2022 expedition to Peru's Amazon, according to Conservation International.

Scientists also discovered a spiny mouse, a squirrel, eight types of fish, three amphibians and 10 types of butterflies, Trond Larsen, head of Conservation International's Rapid Assessment Program, told Reuters this week.

He added that another 48 species found by investigators were potentially new, but needed further study.

The new species were found in Alto Mayo, a protected area with several ecosystems, Indigenous territories and villages.

"Discovering so many new species of mammals and vertebrates is really incredible, especially in such a human-influenced landscape as Alto Mayo," Larsen said.

The expedition between June and July 2022 was made up of 13 scientists plus local technicians and members of Indigenous groups.

"It was really fantastic to work so closely with the Awajun people. They have extensive traditional knowledge about the forests, animals and plants they live side-by-side with," Larsen said.

Among the new species, Larsen highlighted the spiny mouse that has stiff fur, the amphibious mouse, and a dwarf squirrel that measures 14 cm (5.5 in).

"(The squirrel) fits so easily in the palm of your hand. Adorable and beautiful chestnut-brown color, very fast," Larsen said. "It jumps quickly and hides in the trees."

Another favorite discovery was the blob-headed fish, a type of armored catfish, he said.

A total of 2,046 species were recorded during the 38-day expedition using camera traps, bioacoustic sensors and DNA sampling. Among them, 49 were classified as threatened, including the yellow-tailed woolly monkey and the tree monkey.

Larsen said the discoveries reinforced the need to protect the area.

"Unless steps are taken now to safeguard these sites and help restore parts of the landscape ... there's a strong chance they won't persist in the long term," Larsen said.
