It is often said music is the universal language of humanity. Now a 12-year-old Houston boy is putting that to the test among an unlikely audience — man's best friend.

Yuvi Agarwal started playing keyboard when he was 4 and several years ago noticed his playing soothed his family's restless golden doodle, Bozo. He grew curious if it also could help stressed homeless animals.

With help from his parents, who both have backgrounds in marketing, he founded the nonprofit Wild Tunes in 2023 to recruit musicians to play in animal shelters. So far he has enlisted about 100 volunteer musicians and singers of all ages and abilities to perform at nine shelters in Houston, New Jersey and Denver.

“You don’t have to understand the lyrics to enjoy the music. Just enjoy the melody, the harmony and the rhythms. So it transcends linguistic barriers, and even it can just transcend species,” Agarwal said recently after playing hits like The Beatles' “Hey Jude” and Ed Sheeran's “Perfect” on his portable keyboard at the Denver Animal Shelter.

Agarwal, who was playing for an elderly miniature poodle named Pituca — Spanish slang sometimes used to describe a snob — said many of his four-legged listeners, which include cats, become excited when he enters their kennel. But after a few minutes of playing, they calm down. Some even go to sleep.

He remembers a rescue dog named Penelope that refused to come out of her enclosure in Houston to be fed, The Associated Press reported.

“Within a short period of me playing, she went from not even coming out of her kennel to licking me all over my face and nibbling my ears,” Agarwal said.

A few stalls down from where he was jamming on his keyboard at the Denver shelter, volunteer Sarah McDonner played Mozart and Bach on her flute for Max, a 1-year-old stray boxer that tilted his head when she hit the high notes.

“The animals having that human interaction in a positive way, I think, gives them something to look forward to, something that is different throughout their day,” said McDonner, a professional musician who met Argawal in Houston.

She helped bring the program to Colorado after moving to Denver a few months ago. “I think it’s very important to give them something different from what they’re used to in their little tiny cages ... and makes them more adoptable in the long run,” McDonner said.

While the effect of music on humans has been studied extensively, its role in animal behavior remains murky.

Several studies suggest that classical music generally has a calming influence on dogs in stressful environments like kennels, shelters and veterinary clinics.

But some researchers warn there is not enough data to support the claim.

“We always want these really simplistic answers. So we want to say that music calms animals, for example, and I think that it’s much more nuanced than that,” said Lori Kogan, a self-described “dog-person" who chairs the human-animal interaction section of the American Psychological Association. “There’s a lot more research that needs to happen before I think that we can unequivocally say that music is a great thing for animals."

Kogan, a professor and researcher at Colorado State University, has studied for more than two decades how animals and humans get along. Research involving the effect of music on dogs often produces mixed results, she said, because there are so many variables: the setting; the volume, type and tempo of the music and the breed of the dog and its previous exposure to music.

She suggests a case-by-case approach to introducing music to animals.

“If you play music for your pet, and they seem to like it and they appear calmer, then I think we can say that that’s a positive thing, that you’re providing some level of enrichment for that pet. ... I would encourage people to give it a try and to see how their pets respond,” she said.

For Agarwal, his firsthand experience at shelters is undeniable evidence that music helps comfort stressed animals, and he plans to grow Wild Tunes into a nationwide program. The volunteers get something out of it, too, he said.

"You get a really great way to practice your instrument or sing in front of a nonjudgmental audience, which can boost your confidence,” he said.

An Australian dog credited with saving over 100 koalas from bushfires is retiring after a decade of service.

Bear, an 11-year-old Australian Koolie, was one of the first dogs in the country to be trained on the scent of koala fur.

The International Fund for Animal Welfare called using dogs to detect koalas a "novel" approach.

"No one knew if it could be done," IFAW head of programs Josey Sharrad wrote in a statement about Bear on Monday.

As a pup, the four-legged hero's boundless energy made it tough to stay indoors, but he found his true potential in the bush.

"He literally went from chewing the walls of a Gold Coast apartment to roaming through the Aussie bush on a mission to save our most iconic species," Sharrad said.

Bear's skills saved over 100 koalas as the Black Summer bushfires raged across Australia's eastern seaboard from late 2019 to early 2020, razing millions of hectares, destroying thousands of homes and blanketing cities in noxious smoke.

The tail-wagging detective with a "joyful and goofy" personality retires with an extensive list of accolades, including an Animal of the Year award and Puppy Tales Photos Australian Dog of the Year award.

He also features in a "dogumentary" called "Bear: Koala Hero", and in a book, "Bear to the Rescue".

Bear will embark on a slower-paced chapter on the Sunshine Coast with one of his former handlers, getting belly rubs and playing his favorite game, fetch.

One of his former handlers, Romane Cristescu, said Bear had been a "tireless ambassador for koalas for a decade".

"He melted hearts all around the world, and opened many doors so we could have critical and difficult conversations about climate change and its impacts on the threatened koalas, as well as so many other species."


Exotic Pet Trade Thrives in China Despite Welfare Concerns

Pet lovers eagerly gathered around a container to snap photos of meerkats at a Beijing animal fair, each selling for $320, while nearby a raccoon nervously paced in a cage only slightly bigger than itself.

Throngs of people from across China packed into the cavernous exhibition halls for the annual pet fair, where exotic animals are a more common sight than cats or dogs.

The exotic pet industry is experiencing rapid growth with a market nearing 10 billion yuan ($1.45 billion), Chinese state media have said.

Approximately 17.07 million people in China have exotic pets, Xinhua reported last year, and animal rights groups have raised concerns about welfare standards.

Unconventional pets are particularly popular among young people, with videos on how to raise them widely shared on social media platforms.

An 18-year-old putting down a deposit for a meerkat told AFP he was confident it would be easier to raise the animal than his previous cats and dogs.

"I feel that raising exotic pets is really just child's play by comparison," said Xiong, who had travelled to Beijing from Jiangxi province.

He had previously bought a sugar glider -- a nocturnal palm-sized possum sold at the same store -- and said he found raising exotic pets easier as they did not feel separation anxiety as dogs do.

It was "quite a hassle-free" experience, Xiong said.

"When you want to interact, it's happy to engage with you, but when you're not in the mood, it's perfectly content playing by itself," he told AFP.

In another part of the fair, patterned snakes and spotted geckos squirmed in round plastic containers as people shopped for their latest reptile.

Yang Xurui brought his green Argentine snake to the fair, where he told AFP he was searching for new exotic pets.

"I consider her a friend of mine," said Yang, 24, caressing the slithering creature hanging around his neck.

"Every day, the moment I walk through the door, she stands tall and straight like a giant green onion to welcome me home," he added.

"She keeps me company while I watch TV, and then, come evening, she goes off to bed on her own -- marking the end of our day together."

Yang said he feels a certain sense of responsibility to dispel commonplace fear of snakes as pets.

"I want to tell everyone that she isn't terrible, that she isn't something to be feared."

China's Ministry of State Security has warned against the exotic pet craze it says is driven by trend-seekers.

"The trade, rearing, medical treatment, and abandonment of these exotic animals harbor latent safety risks," it said last year, adding that this warrants "serious attention".

Animal welfare regulations, however, remain lax in China, where pets such as fish, birds and pigs are commonly sold even in shopping malls.

The pandemic, meanwhile, sparked fears that animals may be carriers of diseases including Covid-19, which was widely believed to have originated in bats.

Authorities in China should target the traders, breeders, and retailers who depend on the business -- and its expansion -- for profit, said Peter Li, a specialist in China's animal protection policy at the University of Houston-Downtown.

Businesses engaged in the sale and transport of exotic animals have reportedly used fraudulent labeling, withheld critical information, and engaged in deliberate deception to move these animals through supply chains, Li told AFP.

Abandoned exotic species can reproduce rapidly in the wild, creating significant ecological pressures on local environments, while diseases carried by them could pose public health risks, he said.

Public awareness in China regarding wildlife protection has improved significantly, but some consumers of exotic pets still lack sufficient knowledge before purchasing such animals, conservation charity WWF told AFP.

"Some consumers may not be fully aware of which species are legal to own, whether specific permits are required, the varying levels of care difficulty for different species, long-term financial costs," it added.

At the fair, 26-year-old Zhang Yue agreed that bringing certain animals "into human-inhabited environments could lead to various repercussions".

Nevertheless, Zhang told AFP she would still consider owning a sugar glider as they are "absolutely adorable".

Revealing the limitations of cloning, researchers who repeatedly cloned mice for two decades have discovered that such serial duplication triggers grave genetic mutations that accumulate over the generations and ultimately become fatal.

A total of 1,206 cloned laboratory mice were generated by the scientists from a single female donor mouse from 2005 to 2025 in research conducted in Japan. There were no outward signs of trouble through the first 25 generations, but mutations subsequently began piling up until becoming fatal. The 58th generation of clones, burdened by mutations but with no visible physical abnormalities, died within a few days of birth.

The research contradicted the notion that clones are identical copies of the original donor animal and disproved the idea that cloning using current technology could be carried out indefinitely with no ill effects.

"No one has ever continued re-cloning for this long before. As a result, this is the first time we've discovered that repeated re-cloning eventually reaches its limits," said developmental biologist Teruhiko Wakayama of the University of Yamanashi, senior author of the research published on Tuesday in the journal ⁠Nature Communications.

"It was ⁠once believed that clones were identical to the original, but it has become clear through this study that mutations occur at a rate three times higher than in offspring born through natural mating," Wakayama said.

"Because all these mutations continue to accumulate, mammals cannot sustain their species through cloning. This study has revealed one of the reasons why mammals, unlike plants and lower animals, cannot maintain their species through cloning."

After generating the first clone, the researchers repeated the process every three to four months, cloning each generation from the one preceding it. Like the original donor mouse, all the clones were females with brown fur.

The researchers published preliminary results in 2013 spanning the first 25 generations ⁠that found the clones to be healthy, with no apparent negative effects.

"At that time, we concluded that re-cloning could likely continue indefinitely. However, in that study, we did not examine the genetic sequences. We continued our research for 13 more years, and as a result, we discovered that our previous conclusion was incorrect - that is, there is a limit to re-cloning," Wakayama said.

The researchers sequenced the genomes of 10 clones from the various generations to understand what was happening at the genetic level.

They found that serial cloning produced an effect akin to duplicating a picture using a copying machine. With the first copy, the image quality deteriorates slightly. When copying that copied image, the quality deteriorates further.

Repeating the process numerous times yields an image very different from the original.

The study results, they said, pointed to the importance of sexual reproduction in countering deleterious genetic mutations in mammals.

The researchers gauged the fertility of the clones by mating them with ordinary male mice. Up to the 20th generation, they gave birth to about 10 babies per litter, ⁠just like ordinary female mice. But ⁠eventually the clones began having smaller litters, reflecting the effects of accumulating mutations.

The researchers used a technique called nuclear transfer to generate the clones. The same method was used to produce Dolly the sheep, the first successfully cloned mammal, at a laboratory in Scotland in 1996, and Cumulina, the first successfully cloned mouse, at a lab in Hawaii in 1998.

With nuclear transfer technology, researchers create an embryo by transferring the nucleus, a cell's primary repository of genetic information, from a donor cell into an egg cell whose own nucleus was removed. A specialized ovarian cell, called a cumulus cell, that surrounds and nurtures a developing egg was used in the cloning.

"We had believed that we could create an infinite number of clones. That is why these results are so disappointing. At this point, we have no ideas for overcoming this limitation. I believe we need to develop a new method that fundamentally improves nuclear transfer technology," Reuters quoted Wakayama as saying.

An increase in large-scale harmful mutations began with the 27th generation including chromosomal abnormalities. For instance, one copy of the X chromosome was lost.

Chromosomes are threadlike structures that carry genetic information from cell to cell. In mammals, females carry two X chromosomes, one inherited from each biological parent.

"In cloning, all genes are passed on to the next generation, meaning that all defective genes are also passed on," Wakayama said.
