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.

A Rare Plant Emits a Stink of Death When it Blooms. Thousands in Australia Queued to Get Close to It

The rare unfurling of an endangered plant that emits the smell of decaying flesh drew hundreds of devoted fans to a greenhouse in Sydney on Thursday where they lined up to experience a momentous bloom -– and a fragrance evoking gym socks and rotting garbage.
Tall, pointed and smelly, the corpse flower is scientifically known as amorphophallus titanum — or bunga bangkai in Indonesia, where the plants are found in the Sumatran rainforest, The Associated Press said.
But to fans of this specimen, she’s Putricia -- a portmanteau of “putrid” and “Patricia” eagerly adopted by her followers who, naturally, call themselves Putricians. For a week, she has graced a stately and gothic display in front of a purple curtain and wreathed in mist from a humidifier at the Royal Sydney Botanic Garden.
Her rise to fame since has been rapid, with more than 13,000 admirers filing past for a moment in her increasingly pungent presence. No corpse flower has bloomed at the garden for 15 years.
A slow bloomer The plant only flowers every 7-10 years in the wild.
“The fact that they open very rarely, so they flower rarely, is obviously something that puts them at a little bit of a disadvantage in the wild,” said garden spokesperson Sophie Daniel, who designed Putricia's kooky and funereal display. “When they open, they have to hope that another flower is open nearby, because they can’t self-pollinate.”
There are thought to be only 300 of the plants in the wild and fewer than 1,000 worldwide — including those in cultivation. Among them is Putricia, which arrived at the garden seven years ago.
When her flower was spotted in December she was just 25 centimeters (10 inches) high. By Thursday, she was 1.6 meters (5 feet 3 inches) tall -– and her flower spike was slowly opening like a pleated skirt around a majestic central tuber, the yellow-green outer curling to reveal a burgundy center.
Putricia-mania builds As excitement grew in Sydney about the moment of her bloom, garden staff erected crowd barriers, giving the Victorian greenhouse the air of a rock concert. Fans trod a red carpet to view Putricia from behind velvet ropes in a display inspired by Queen Victoria’s funeral, the Rocky Horror Picture Show and the oeuvre of the late director David Lynch.
Inside, fans took selfies and leaned in for a sniff — an increasingly perilous prospect as Putricia's odor developed. One young woman raised her hands and bowed as though in worship. On social media, garden staff performed a viral dance to Chappell Roan’s summer hit HOT TO GO! against a backdrop of the stately plant.
It was difficult to say why the regal, mysterious and stinky flower had attracted such a following -– but perhaps the answer lay in the “reverence” viewers felt in the presence of “such an amazing living being,” Daniel said.
A swift rise to online fame Along with her real-life visitors, Putricia’s online fandom has been rapid, global and deeply strange -– if much less smelly. A 24/7 live stream established by the botanic garden drew close to a million views in less than a week and a shared language of memes and inside jokes sprang up.
Frequently deployed acronyms included WWTF, or we watch the flower, WDNRP -- we do not rush Putricia – and BBTB, or blessed be the bloom. “Putricia is a metaphor for my life,” wrote one poster, who did not elaborate.
Commenters on social media made plans to hurry to the garden as the plant opened. In just 24 hours, Putricia’s bloom -– and her stench -– would be gone.
As she unfurled, Putricia would heat to 37 degrees Celsius (100 F) to better spread her scent, Daniel said, attracting flies and carrion beetles to burrow inside and lay eggs. Then, work will begin to hand-pollinate the plant in efforts to ensure the species' diversity and survival.
But first, thousands of Putricians will attempt to get as close as they can to their hero of a week.
“We did have a few conversations early on about whether or not we should have vomit bags in the room," said Daniel, adding that garden staff ultimately decided against it. “I haven’t heard of anyone actually being harmed."
