HOBART, Australia (AP) — About 230 whales have been stranded on Tasmania’s west coast, just days after 14 sperm whales were found beached on an island off the southeastern coast.
The pod stranded on Ocean Beach appears to be pilot whales and at least half are presumed to still be alive, the Department of Natural Resources and Environment Tasmania said Wednesday.
A team from the Marine Conservation Program was assembling whale rescue gear and heading to the area, the department said.
A resident told the Australian Broadcasting Corp. that the whales were visible near the entrance to Macquarie Harbour and described the stranding as a “massive event.”
David Midson, general manager of the West Coast Council, urged people to stay clear.
“Whales are a protected species, even once deceased, and it is an offense to interfere with a carcass,” the environment department said.
Griffith University marine scientist Olaf Meynecke said it’s unusual for sperm whales to wash ashore. He said that warmer temperatures could also be changing the ocean currents and moving the whales’ traditional food.
“They will be going to different areas and searching for different food sources,” Meynecke said. “When they do this, they are not in the best physical condition because they might be starving so this can lead them to take more risks and maybe go closer to shore.”
Fourteen sperm whales were discovered Monday afternoon on King Island, part of the state of Tasmania in the Bass Strait between Melbourne and Tasmania’s northern coast. The department said it is not unusual for sperm whales to be sighted in Tasmania.
The pilot whale is notorious for stranding in mass numbers, for reasons that are not entirely understood.
Two years ago, about 470 long-finned pilot whales were found beached on sandbars off Tasmania’s west coast in the largest mass-stranding on record in Australia. After a weeklong effort, 111 of those whales were rescued but the rest died.
3 physicists share Nobel Prize for work on quantum science
STOCKHOLM (AP) — Three scientists jointly won this year’s Nobel Prize in physics on Tuesday for their work on quantum information science that has significant applications, for example in the field of encryption.
Frenchman Alain Aspect, American John F. Clauser and Austrian Anton Zeilinger were cited by the Royal Swedish Academy of Sciences for discovering the way that unseen particles, such as photons or tiny bits of matter, can be linked, or “entangled,” with each other even when they are separated by large distances.
“Being a little bit entangled is sort of like being a little bit pregnant. The effect grows on you,” Clauser said in a Tuesday morning phone interview with The Associated Press.
It all goes back to a feature of the universe that even baffled Albert Einstein and connects matter and light in a tangled, chaotic way.
Clauser, 79, was awarded his prize for a 1972 experiment that helped settle a famous debate about quantum mechanics between Einstein and famed physicist Niels Bohr. Einstein described “a spooky action at a distance” that he thought would eventually be disproved.
“I was betting on Einstein,” Clauser said. “But unfortunately I was wrong and Einstein was wrong and Bohr was right.”
Clauser said his work on quantum mechanics shows that you can’t confine information to a closed volume, “like a little box that sits on your desk” — though even he can’t say why.
“Most people would assume that nature is made out of stuff distributed throughout space and time,” Clauser said. “And that appears not to be the case.”
Quantum entanglement “has to do with taking these two photons and then measuring one over here and knowing immediately something about the other one over here,” said David Haviland, chair of the Nobel Committee for Physics. “And if we have this property of entanglement between the two photons, we can establish a common information between two different observers of these quantum objects. And this allows us to do things like secret communication, in ways which weren’t possible to do before.”
That’s why quantum information is not an esoteric thought experiment, said Eva Olsson, a member of the Nobel committee. She called it a “vibrant and developing field.”
“It has broad and potential implications in areas such as secure information transfer, quantum computing and sensing technology,” Olsson said. “Its predictions have opened doors to another world, and it has also shaken the very foundations of how we interpret measurements.”
Everything in the universe could be entangled but “usually the entanglement just kind of washes off. It’s so chaotic and random that when you look at it … we don’t see anything,” said Harvard professor Subir Sachdev, who has worked on experiments that look at quantum entangled material consisting of up to 200 atoms. But sometimes scientists can unsnarl just enough to make sense and be useful in everything from encryption to superconductors, he said.
Speaking by phone to a news conference after the announcement, Zeilinger said he was “still kind of shocked” at hearing he had received the award.
“But it’s a very positive shock,” said Zeilinger, 77, who is based at the University of Vienna.
Clauser, Aspect, and Zeilinger have figured in Nobel speculation for more than a decade. In 2010 they won the Wolf Prize in Israel, seen as a possible precursor to the Nobel.
While physicists often tackle problems that appear at first glance to be far removed from everyday concerns — tiny particles and the vast mysteries of space and time — their research provides the foundations for many practical applications of science.
The Nobel committee said Clauser developed quantum theories first put forward in the 1960s into a practical experiment. Aspect, 75, was able to close a loophole in those theories, while Zeilinger demonstrated a phenomenon called quantum teleportation that effectively allows information to be transmitted over distances.
“Using entanglement you can transfer all the information which is carried by an object over to some other place where the object is, so to speak, reconstituted,” said Zeilinger. He added that this only works for tiny particles.
“It is not like in the Star Trek films (where one is) transporting something, certainly not the person, over some distance,” he said.
When he began his research, Zeilinger said the experiments were “completely philosophical without any possible use or application.”
Since then, the laureates’ work has been used to develop the fields of quantum computers, quantum networks and secure quantum encrypted communication.
A week of Nobel Prize announcements kicked off Monday with Swedish scientist Svante Paabo receiving the award in medicine Monday for unlocking secrets of Neanderthal DNA that provided key insights into our immune system.
They continue with chemistry on Wednesday and literature on Thursday. The 2022 Nobel Peace Prize will be announced on Friday and the economics award on Oct. 10.
The prizes carry a cash award of 10 million Swedish kronor (nearly $900,000) and will be handed out on Dec. 10. The money comes from a bequest left by the prize’s creator, Swedish inventor Alfred Nobel, who died in 1895.

Prairie premiers, governors urge Canada, U.S. to keep border crossings open longer
Washington – Canada’s Prairie premiers and two U.S. governors want their respective countries to restore pre-pandemic operating hours at entry points along their shared land border.
The group of provincial and state leaders have written to Prime Minister Justin Trudeau and President Joe Biden to argue that curtailed hours at border crossings are hurting the economy.
The letter is signed by Alberta Premier Jason Kenney, Saskatchewan Premier Scott Moe and Manitoba Premier Heather Stefanson, as well as Montana Gov. Greg Gianforte and North Dakota Gov. Doug Burgum.
It says travellers and businesses are being forced to go out of their way to find entry points with longer hours, driving up fuel and labour costs.
The leaders say that’s also hurting smaller border communities along the Canada-U.S. border that depend on international traffic for their economic livelihoods.
The letter does not mention that the U.S. still requires visiting foreign nationals to be vaccinated against COVID-19, a requirement Canada lifted over the weekend.
“Residents and businesses on both sides of the border have expressed concern that the reduced hours of operation will become permanent,” the letter reads.
It also argues that the supply chain problems that have persisted since the onset of COVID-19 in 2020 will only linger so long as cross-border trade and travel remains curtailed by limited hours at border crossings.
“Resuming pre-pandemic operating hours will ensure the efficient and steady flow of people and goods, which will only improve trade activity and reduce inflationary pressure on both sides of the border.”
A notice on the Canada Border Services Agency website warns of limited operating hours at nearly 40 land ports of entry, mostly in the Prairie provinces, along with Quebec, New Brunswick and B.C.
