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.

Powerful winds and bone-dry conditions were expected to pose a challenge to firefighters battling new wildfires in southern California on Thursday, including a new blaze that swelled over the past day, forcing tens of thousands of people to evacuate north of Los Angeles.

The Hughes fire, about 50 miles (80 km) north of Los Angeles, grew to 10,176 acres (4,118 hectares) since igniting on Wednesday morning, the California Department of Forestry and Fire Protection, or Cal Fire, said on its website.

The 4,000 firefighters battling the blaze have achieved 14% containment, a measure of the percentage of a fire's perimeter that is under control, Cal Fire added.

Crews fighting the Hughes Fire and two other massive Los Angeles blazes - Palisades and Eaton - were expected to be tested by strong Santa Ana winds of up to 50 miles (80 km) per hour with gusts reaching 65 miles (105 km) per hour and humidity levels dropping below 10% throughout the day and into Friday, forecasters said, Reuters reported.

"Dangerous fire weather conditions will persist through Friday as fuels remain extremely dry and ready to burn, with Thursday the period of greatest concern," the National Weather Service said in an advisory. "Any fire that starts can grow fast and out of control."

About 31,000 people were evacuated on Wednesday as the fire sent huge flames and plumes of smoke over a hilly terrain in the Castaic Lake area near Santa Clarita.

The Eaton and Palisades fires, which leveled entire neighborhoods on the eastern and western flanks of Los Angeles, have killed 28 people and damaged or destroyed nearly 16,000 structures over the past two weeks.

Helicopters battling the Hughes Fire scooped water out of a lake to drop on the fire while airplanes dropped fire retardant on the hills, video on KTLA television showed. Flames spread to the water's edge.

Eyewitness video showed the skies north of Los Angeles tinted orange on Wednesday afternoon as the Hughes Fire expanded rapidly.

A smaller blaze, called the Sepulveda Fire, was burning along the 405 freeway near the Getty Museum - home to numerous art treasures - in the San Fernando Valley on Thursday. The brush fire, which was 40 acres (16 hectares) and 0% contained, briefly caused part of the heavily traveled highway to be closed and some nearby residents to be evacuated overnight.

Southern California has gone without significant rain for nine months, contributing to hazardous conditions, but some rain was forecast from Saturday through Monday, possibly giving firefighters much-needed relief.

As of Thursday morning, the Eaton Fire that scorched about 14,000 acres (5,670 hectares) east of Los Angeles was 95% contained, while the larger Palisades Fire, which has consumed about 23,450 acres (9,490 hectares) on the west side of Los Angeles, stood at 70% contained, Cal Fire said.
