Lions typically aren't keen on making new friends. The giant cats guard their territory fiercely and can mortally wound a foe with a single swipe. While aggression is an advantage for apex predators in the wild, it poses real challenges for lions on reserves or in captivity, a number that is growing due to habitat loss.

Researchers working on a wildlife reserve in Dinokeng, South Africa, found that an intranasal application of the "love hormone" oxytocin could make lion meet-cutes less life-threatening. Their work appeared March 30 in the journal iScience.

In the summers of 2018 and 2019, a team led by animal biologist Craig Packer and neuroscientist Sarah Heilbronner from the University of Minnesota spent their days using hunks of raw meat to lure lions up to a fence so they could spray oxytocin up their noses with a tool that looks like an antique perfume bottle.

By spraying the oxytocin directly up the nose, it can travel up the trigeminal nerve and the olfactory nerve straight up into the brain.

After these treatments, researchers observed that the 23 lions who were given oxytocin were more tolerant of other lions in their space and displayed less vigilance towards intruders.

"You can see their features soften immediately, they go from wrinkled and aggressive to this totally calm demeanor. They totally chill out. It's amazing," said Jessica Burkhart from the Department of Ecology, Evolution and Behavior at the University of Minnesota, in a report posted on the Cell Press network.

Researchers measure social tolerance by seeing how close a lion who has possession of a desired object, in this case a pumpkin toy, will let others approach it.

"After the lions were treated with oxytocin, and we gave them their favorite pumpkin toy to play with, we saw the average distance between them drop from about 7 meters with no treatment to about 3.5 meters after oxytocin was administered,” added Burkhart.

A man died on Friday after being mauled by a shark while swimming at a popular beach in the state of Western Australia, police said.

It is the latest in a spate of shark attacks in the country and comes just days after a surfer was bitten in an attack in the same state.

The Western Australia Police Force said emergency services were called to a reported shark-related incident in the water off Sorrento Beach ⁠at around 10.30 ⁠a.m. local time (0230 GMT).

"It was reported a male swimmer had been bitten by a shark while swimming along the coast," WA Police said in a statement.

Authorities launched an extensive air and sea search, but the swimmer died ⁠as a result of the attack, the statement said, according to Reuters.

Sorrento Beach is a popular swimming spot around 20 km (12.5 miles) from Perth's central business district. The local council said it closed down all beaches in its jurisdiction after the attack.

A 5-meter-long (16.4-foot) white shark was reported to monitoring website SharkSmart at the nearby Boyinaboat reef just after noon on Friday. There was no confirmation that ⁠it ⁠was the shark involved in the attack.

On Monday, a surfer was attacked at a beach in the town of Geraldton, around 400 km north of Perth. The surfer lost his foot in the attack and suffered serious leg injuries, local media said.

It follows the death of a 35-year-old man killed while spearfishing off the state's south coast in June, while a 38-year-old man was mauled to death off an island near Perth in May.


Australia to Detain Tourists Who Overstay Visa, Minister Says

Australia to Detain Tourists Who Overstay Visa, Minister Says

Australia will detain tourists who overstay visas to send a message of deterrence under new rules aimed at reducing levels of migration, a minister said on Friday.

Australia's ruling Labor party has denied it is tightening visa rules in response to the rise of the far-right One Nation, which has become one of the country's most popular parties this year with pledges to drastically slash migration.

Under reforms announced Thursday, Australia will stop family members accompanying students, introduce ballots for working holiday makers and crack down on overstayers.

Assistant Minister for Foreign Affairs Matt Thistlethwaite said on Friday that tourists would be put in immigration detention to reduce the level of visa overstayers, which has risen to 77,000.

"Once the word gets around, 'hey, I overstayed on my tourist visa for a couple of weeks, I got picked up and I spent a couple of weeks in immigration detention, it's not a nice place, I'm going home'. Once that gets around, then we think that obviously that deterrence will ensure that people abide by the conditions," he told broadcaster News24.

People who don't have the right to remain in Australia will face a "consequence" and be removed, he added.

Since 2015, Australia's immigration detention centers have swelled with people with criminal convictions awaiting deportation after a policy change that saw mandatory cancellation of permanent visas for certain criminal offences.

Immigration Minister Tony Burke, announcing the new policy on Thursday, said the government would open 250 beds and add 100 compliance officers to house the visa overstayers in different facilities.

Australian Tourism Industry Council chief executive Erin McLeod said talk of detaining tourists was not good for Australia's image.

"I don't think it does our reputation as a welcoming destination any good and can become quite damaging -- tourism is an important part of the Australian economy," she told AFP.

The council represents thousands of small tourism businesses.

Refugee Council of Australia director of policy Rebecca Eckard said the move raised safety and legal concerns.

"It is being framed as punitive to change behavior. The use of punitive detention is not permitted under Australia's immigration act," she told AFP.

"There has been a major problem with immigration detention," she added, pointing to concerns raised by the government ombudsman over insufficient staffing and healthcare access.


Baby Orangutans in India Expose 'Frightening' Scale of Trafficking

Five baby orangutans abandoned in an Indian forest have exposed a "massive" exotic wildlife trade, with traffickers smuggling increasingly rare species into the country, experts say.

They warn of a growing multi-million-dollar trade in endangered animals, including apes smuggled through war-torn Myanmar to feed demand among wealthy Indians seeking exotic status symbols to flaunt on social media.

"There have been several instances of exotic wild animals being found or seized across the country, said Sumanth Bindumadhav of Humane World for Animals India. "The scale is massive."

Critically endangered orangutans are native only to Indonesia's Sumatra island and Borneo, which it shares with Malaysia and Brunei.

Yet the five tiny orangutans were found by rangers in Balasore, in India's eastern Odisha state.
Aged around one-and-a-half years old, they are being cared for at a zoo. Indonesia has requested their return.

Bindumadhav's group, in a June 2026 report, detailed what it called a "rising trade in exotic wildlife", demonstrated by a "steep increase in seizures" that reflected a "surge in illegal trade".

The report estimated India's exotic-pet market at $42.6 million in 2024.

Orangutans and gibbons, small apes, were being "increasingly trafficked into India" from Southeast Asia's rainforests, it added.

A senior official at India's Wildlife Crime Control Bureau said "thousands of social media influencers" were promoting exotic species as pets online, fueling demand among followers.

"It is a huge market," said the official, who requested anonymity because they were not authorized to speak to the media. "Rich people keep them in their homes."

Under a government voluntary disclosure scheme, more than 40,000 people had registered exotic animals by February 2021, government data shows.

The figure is likely only a fraction of those in private hands, analysts say.

"This is a figure from only those who registered themselves, so the true volume of it is potentially much larger and remains unknown," said Bindumadhav.

"The true scale of it is actually quite frightening."

Former India head of global anti-wildlife-trade group TRAFFIC Shekhar Kumar Niraj said the surge in trafficking was also linked to a "rising number" of animals held in private hands.

"Private zoos have violated laws at a very alarming scale across the country," said Niraj.

"Primates are very popular in zoos because they are very intelligent, like to interact with humans, the kind of thing zoos want."

Indian federal authorities did not respond to AFP's requests for comment.
The World Wide Fund for Nature-India (WWF-India) documented 56 seizures involving about 4,000 exotic animals in 2022 alone.

In October 2025, Mumbai customs officers arrested a passenger carrying two endangered gibbons stuffed inside a checked bag.

Other seizures in Mumbai last year included lizards, tree-climbing possums and dozens of venomous vipers.

In 2024, forest officials recovered a trafficked orangutan from a flat in Maharashtra state.
But such seizures represent only a fraction of the trade, experts warn.

"The scale of it is much, much bigger than what we see actually based on the seizure data," said Jimmy Borah of the environmental advocacy group Aaranyak.

Experts have previously raised concerns over Vantara, a vast wildlife rescue and conservation center in Gujarat founded by Anant Ambani, son of billionaire Mukesh Ambani, over its intake of endangered species.

Vantara has consistently denied any wrongdoing.

In August, it said it was taking "bold steps to reset its operations", had withdrawn all applications to import live animals, and named former head of the global wildlife watchdog CITES, John Scanlon, to chair its governing council.

Exactly how the orangutans were brought to Odisha -- more than 2,000 kilometers (1,200 miles) by sea, and 7,000 kilometers by land (4,500 miles) -- is not clear. Police have launched a criminal investigation.

Experts say that in addition to airports and formal cargo routes, the land border between Myanmar and India's northeast is a key trafficking route.

"The northeast is important for seizures of live exotic animals, linked to cross-border movement from Southeast Asia," AFP quoted Dipankar Ghose of WWF-India as saying.

Authorities have seized other exotic primates in the region in recent years, smuggled on jungle routes across the frontier.

"We are talking about miles and miles of a very porous border," said Borah of Aaranyak.
