Laboratory Rats Become Festival Stars in Argentina

A group of people watched three albino rats leap from small baskets into a big cage on Sunday as other rodents hid in makeshift tunnels or searched for applesauce offered by their keeper through the bars at an indoor hall in the Argentine capital.

It's Ratapalooza, an annual Buenos Aires event that promotes the adoption of rodents raised in animal facilities or used for research in science labs — once the animals are no longer useful, have outlived their purpose or are just surplus stock.

To attract adoptive families, Team Ratas, which is Spanish for rats, organizes events such as the Ratapalooza. In Argentina, keeping rats or mice as pets is perfectly legal — as long as they are not wild, according to The Associated Press.

The whole thing turns into something of a fair, complete with stalls selling keychains, mugs, stickers and hair clips in the shape of rats and mice.

The money raised goes to veterinary and food expenses for the rodents, which they foster at home before putting them up for adoption.

At one of the stands, Maria Gabriela Aponte held Camamberto, one of the three rats she has adopted, as she sold vegan food, mouse-shaped pins and stickers.

All of them, she said, were raised in labs, in what is called a vivarium, where laboratory animals are kept under strictly controlled conditions.

“People don’t really know, or they have a very specific perception of, what a pet is,” Aponte told AP. “Rats are very intelligent and sweet.”

Dominique Verdier, who represents Team Ratas, says those interested in adopting rodents must have access to a veterinarian specialized in exotic animals, a spacious cage with lots of accessories for their entertainment — and devote at least one hour a day to quality time spent with their adoptees.

Team Ratas is a leader in Argentina and Latin America for rehoming lab rats and mice that — without a foster home — would otherwise be euthanized.

The initiative started in 2016, when Verdier adopted two rats after a friend told her the university where they were used for research no longer needed them.

She set up a rodent rescue network with 90 foster homes in Buenos Aires and nearby towns, housing hundreds of animals from 11 animal facilities and labs. In the last 10 years, she has rescued more than 8,000 animals and found homes for approximately 3,000.

Her organization has more than 60,000 followers on Instagram.

Proximity to rats and mice — and rodents in general — may be raising concerns amid the ongoing deadly hantavirus outbreak on the ill-fated Atlantic cruise ship MV Hondius after the ship stopped in Argentina earlier this month.

Hantavirus is usually spread by breathing in droppings of contaminated wild rodents, which usually live in Patagonia, in southern Argentina.

Verdier, who fosters most of the 37 rodents at her home, stresses that lab rats are perfectly healthy.

“They do not transmit diseases because they have not had contact with the street nor are they inoculated with viruses and bacteria,” she said.

The labs that have been supplying Team Ratas for years only provide animals that have not been infected with any viruses or bacteria.

“Several laboratories prefer to euthanize the animals, while others tell me, ‘Take them away, we don’t want to sacrifice them’,” she added.

Veterinarian Silvina Diaz, at the University of Buenos Aires, studies the nervous system of rats and mice at an experimentation laboratory.

She supports having the rodents find a new home once their lab careers are over.

“It is great that they’re doing this work of rehoming animals in families that can give them a good life,” said Diaz, who acts as a liaison between vet technicians and Team Ratas.

Verdier, who insists she will keep finding new homes for the little furry creatures, says she is used to the criticism she gets on social media.

“If people see a dog shelter, they might admire it, but when I mention Ratapalooza they say, ‘What you’re doing is silly’,” she said. “And I say that I’ve been doing this for 10 years and it keeps growing.”

A leather bag made from Tyrannosaurus rex cells failed to sell on Thursday, the Paris auction house Drouot said, commenting that bids were well below expected.

Auctioneers Giquello had touted the "one-of-a-kind" piece to sell for more than $500,000 but bids barely broke the $150,000 mark, said the Drouot house where the sale took place.

Unveiled in the spring in Amsterdam, the bag was created from traces of collagen from the femur of a T-Rex found in the US state of Montana 25 years ago.

"In recent years, we've developed techniques -- biotechnologies that allow us to instruct a cell culture to produce, so to speak, genuine T-Rex skin in the laboratory," Iacopo Briano, a paleontology expert associated with the sale, recently told AFP.

He noted the material differs from vegan leather, which is mostly made from plastic.

"In this case, it's derived from a cell culture, so it's 100 percent skin. And at the same time, it comes from an animal that went extinct 67 million years ago!" he said.

With no precedent to go on, Alexandre Giquello, whose auction house is organizing the sale, explained they had to "come up with a price" that would reflect both the amount of investment required to create the bag and its rarity.

Giquello estimated the value at between 300,000 and 500,000 euros ($346,000 to $576,000).

Temperatures in the Antarctic Peninsula have reached a record-breaking high of 15.4C for June, and ice is melting at abnormal rates during the current winter, climate scientists told AFP on Thursday.

Esperanza Base, an Argentine research station located in the north of the peninsula, recorded the unprecedented figure on June 6.

The previous highest temperature on record for that month -- 13.3C -- dates back to 1998. The current heat also significantly exceeds Esperanza's June average of -6.2C.

Such a figure is "very unusual for this time of year," Jose Luis Stella, a climatologist at Argentina's National Meteorological Service, told AFP.

Argentine bases Marambio and San Martin also recorded unequalled temperatures between June 5 and 6.

Marambio recorded 11.8C, surpassing a previous high of 9.2C and its June average of -10.7C.

San Martin meanwhile saw 9.4C compared to its previous 7.8C record and June average of -5.6C.

The northern Antarctic heatwave is not an isolated event, University of Groningen professor Raul Cordero told AFP.

"It confirms a trend," he said, warning that "these kinds of events will continue to occur with increasing frequency" if global warming is not derailed.

Thomas Caton Harrison, a polar climate scientist at the British Antarctic Survey, believes a combination of factors including climate change resulted in the current heat.

"There is credible evidence that climate change is playing a role, but the effect is complex in this region," he said.

"Because Antarctica sees such big swings in temperature, we have to collect lots of data over many years to build a picture of the underlying climate."

Both specialists agree that regional temperatures have been rising for years and are already showing visible effects.

"A surprising amount of precipitation has been falling as rain rather than snow," Caton Harrison said.

"This has implications for polar ecosystems such as penguin colonies," he said, adding that "it poses a challenge to my colleagues working on Antarctic bases because a lot of liquid rain has been falling and creating runoff and ice."

Esperanza Base has been recording above-zero temperatures daily for three consecutive weeks.

This trend has caused "large areas in the far north of the white continent to remain free of snow," according to Cordero, who called it "an unusual scene in the Antarctic landscape during winter."

Japan's flagship H3 rocket carrying six small satellites lifted off Friday, live footage showed.

Friday's launch comes after the H3 rocket failed to launch a geolocation satellite into orbit in December due to engine failure.

"The second stage combustion, action control and trajectory are all normal," the Japan Aerospace Exploration Agency (JAXA) said in a live YouTube broadcast, about six minutes after lift-off.

The satellites loaded onto the rocket include Tokyo University of Science's "Umitsubame" which observes the Earth and other targets with a high-performance camera, and Shizuoka University's "Shiraito" that is testing space debris capture technology, JAXA said.
