    Elizabeth Ann - Hắc cước hồ: Thú nhân tạo trong Tối thế ký.




    Scientists have cloned the first U.S. endangered species, a black-footed ferret duplicated from the genes of an animal that died over 30 years ago.

    The slinky predator named Elizabeth Ann was born in a Colorado facility Dec. 10 and announced Thursday.


    Elizabeth Ann is a genetic copy of a ferret named Willa who died in 1988 and whose remains were frozen in the early days of DNA technology.

    Baarack, a sheep rescued in Australia with over 75 pounds of wool, is 'getting more confident every day'
    https://news.yahoo.com/baarack-sheep...135949204.html

    A sheep named Baarack received a much needed shearing after rescuers in Australia found the abandoned animal with more than 75 pounds of wool weighing it down.

    Edgar’s Mission Farm Sanctuary, an animal rescue and sanctuary on a farm in Lancefield, north of Melbourne, rescued the sheep earlier this month and shared video of his transformation on TikTok that has more than 18.5 million views.

    It was "a property maintenance man who spotted Baarack in the forest that adjoined the boundary of a property he was working on. This chap then contacted us to see if we could assist Baarack," said Kelly Dinham, who works on community engagement and advocacy at the sanctuary, in an email to USA TODAY.



    Kyle Behrend, also with the sanctuary, told Reuters that it appeared that the animal was once owned, having an ear-tag that appeared to have been torn out by the thick matted fleece near his face.

    Sheep need at least yearly shearing to keep their coats light enough for the animals, otherwise it will continue to grow, Dinham told USA TODAY.

    "This is a result of domestication as the ancestor of modern sheep, the wild mouflon was a self-shedding animal whose coat/fur grew and shed in accordance with the seasons," she said.


    After rescuing Baarack, sanctuary staff gave him the long-overdue shearing and found the fleece clocked in at 35.4 kilograms, or about 78 pounds.


    Despite his heavy fleece, Baarack was actually underweight after being sheared, Dinham said.


    The wool around his face impaired his vision, too. Dinham said they found grit and debris "pooling in the gap between his cornea and the lid." And a grass seed stuck in there had caused an ulcer.


    One positive was that Baarack's hooves were in good conditions having been in the forest with rocks to run over for some time, Dinham said.

    Một con bò đau, cả tàu bỏ mạng:

    Cattle stranded on ship in Spain must be destroyed, say vets
    https://www.theguardian.com/world/20...royed-say-vets

    More than 850 cows that have spent months aboard a ship wandering across the Mediterranean are no longer fit for transport any more and should be killed, according to a confidential report by Spanish government veterinarians.

    The cows have been kept in what an animal rights activist called “hellish” conditions on the Karim Allah, which docked in the south-eastern Spanish port of Cartagena on Thursday after struggling for two months to find a buyer for the cattle.

    The animals were rejected by several countries over fears they had bovine bluetongue virus. The insect-borne virus causes lameness and haemorrhaging among cattle. Bluetongue does not affect humans.

    The vets’ report, which was seen by Reuters, concluded that the animals had suffered from the lengthy journey. Some of them were unwell and not fit for transport outside of the European Union, nor should they be allowed into the EU. Euthanasia would be the best solution for their health and welfare, it said.

    The insect-borne bluetongue virus causes lameness and haemorrhaging among cattle but does not affect humans. The Spanish ministry’s report counted 864 animals alive on board the Karim Allah this week. Twenty-two cows had died at sea with two corpses still onboard, it noted, adding that the remains of the others that died were chopped up and thrown overboard during the journey.

    Masramón said although he was not an animal health technician, he did not agree with the official Spanish veterinary report released on Friday. “From what I understand, none of the diseases [noted in the report] are worth euthanizing the cattle for. They are normal after two months at seas and the animals could recover.”

    In an interview, a source close to a second cattle ship, the Elbeik, which has similarly been at sea for two months since leaving the Spanish port of Tarragona with a cargo of nearly 1,800 cows, said he was watching the Karim Allah developments closely.

    The Elbeik is currently moored off the Turkish Cypriot port of Famagusta having loaded animal fodder and straw. The source
    said that once the loading was complete, the Elbeik would probably sail to Greece to load bunker fuel for the ship.

    Asked about apparent moves by the Spanish authorities to begin unloading and killing the cattle, the source said the health problems identified by the official Spanish vet report could “easily heal”. He said the decision, if taken, to kill all the animals was “amazing”. He added: “If the animals can heal why would they want to do that?”
    Poor cows.

    Elephant kills Spanish zookeeper with one hit from trunk
    https://www.theguardian.com/world/20...low-from-trunk

    The female elephant weighing around 4,000kg (8,800lb) hit the 44-year-old with her trunk on Wednesday morning at the Cabarceno Natural Park near the northern city of Santander, the zoo said. The man was rushed to hospital where he died from his injuries some three hours later.

    At the time staff were cleaning the elephant stables as part of their daily duties and the elephant was with her calf in the compound.
    “We’re talking about unpredictable animals,” said Javier Lopez Marcano, the tourism minister in the regional government of Cantabria which owns the zoo.

    “The force of the strike was tremendous, of a magnitude that one could not survive.”

    Police and the zoo said they had opened an investigation. It is the first such incident in the park’s 31-year history.

    Cabarceno Natural Park is home to almost 120 animal species including wolves, tigers, lions and jaguars that live in large enclosures where one or more species co-exist.

    Last year a 46-year-old keeper was mauled by a 200-kilo gorilla at Madrid Zoo Aquarium, leaving her with two broken arms and chest and head injuries.

    Bird trafficking in Iraq
    https://www.theguardian.com/environm...cking-industry

    Bird poaching can be a lucrative business in Maysan, which is located between the Ahwar marshes – a Unesco world heritage site – and the border with Iran, putting it at the forefront of bird trafficking. The region is a poor one and the illegal trafficking of birds is a lifeline for many families.

    In his small bricked house in Amara’s suburbs, Ali admits selling various species of birds, mostly to rich Iraqis or foreigners from the Gulf states. “They travel all the way here from countries such as Kuwait, Saudi Arabia or even Qatar,” he says.

    On his rooftop, he opens the gate of a large cage full of chattering flamingos. “People want them to decorate their gardens, or to put them in their private zoos. I’m the one supplying many Iraqi buyers.


    “Many flamingos die in my cage, especially during warm summer days,” he admits, adding: “I sell between one and 10 of those birds every month during winter, the peak season. They buy them dead or alive, because people also eat them.”

    It is during the winter months of October to February that the birds migrate towards the southern Iraqi marshes, where temperatures are milder and there is an abundance of food. Those that are captured are sold for 30–40,000 Iraqi dinars (£15–£20).

    Holding a flamingo tightly under his arm, Ali says the police are no threat to his business, despite a local decree banning flamingo poaching. Nonetheless, he remains cautious, adding: “I don’t bring flamingos into my shop. No need … people know where to find me, and if they do want one, they meet me at home or I can deliver the bird directly to their place.”

    Dr Hamoudi knows this area well. “Each year, thousands of birds are captured in the marshes. I know the hunting grounds well, so I sometimes give information to the environmental police in order to help them in their operations. They’d be unable to conduct them otherwise,” he says. He also regularly buys wild animals on the black market only to release them afterwards. “So far, I’ve freed 17 flamingos and many other animals from poachers.”

    A sea slug’s detached head can crawl around and grow a whole new body

    Yes, planarians too regrow bodies but don’t have as many fancy organs such as a heart


    The detached head of a sea slug (Elysia cf. marginata) glides by its still-living, leaf-shaped body a day after separation. That body, 80 percent of the animal’s weight, is out of luck. It’s the head that survives, growing a new body.

    S. Mitoh



    March 8, 2021 at 11:00 am

    Losing your body from the neck down can be just another one of life’s annoying, but temporary, setbacks — at least for two kinds of rippling, green-tinged sea slugs.

    Heads of young Elysia cf. marginata sea slugs can pull themselves free from their bodies and just keep crawling around while growing a new body, report ecologists at Nara Women’s University in Japan. Within a few hours, some separated heads start nibbling on algae again, Sayaka Mitoh and Yoichi Yusa report March 8 in Current Biology. And within about 20 days, a third of the young sea slugs they watched had grown their bodies back, heart and all.

    That’s the first time anyone has reported such dramatic “whole-body” regeneration in any sea slug “as far as we know,” Yusa says.


    After disconnecting its head from its body (far left, arrow points to the heart), a process that can take several hours, an Elysia cf. marginata sea slug gradually grows a whole new body. By day 7 (second from left), the heart has begun to regenerate. The rest of the body follows suit (day 14, second from right) until regeneration is complete (day 22, far right).S. Mitoh and Y. Yusa/Current Biology 2021

    Other creatures can regenerate, too. In one sense, planarians, the little cross-eyed flatworms that biology students mince up to study regeneration, “are better,” Yusa says. They can regenerate the whole body from multiple cut pieces. Yet their body plan is simpler, and they don’t have hearts.

    A group of tubelike sea squirts called ascidians might be considered the most complex of whole-body regenerators. Yet ascidians also lack a heart. And vertebrate regenerators, like salamanders regrowing a tail left in the jaws of a predator, don’t regrow a whole body from a severed head.

    Mitoh first noticed the sea slugs’ extreme regeneration by chance in some Elysia slugs in the lab. “We were really surprised to see the head crawling,” Yusa says.

    Just which Elysia species can turn into crawling heads isn’t clear yet. Marine biologist Sónia Cruz at the University of Aveiro in Portugal works with two other Elysia species but hasn’t seen anything like it. She does caution, though, that she hasn’t done systematic tests.

    The head of a sea slug can take several hours to rip itself loose from its body, so Mitoh and Yusa doubt that de-heading helps when predators attack. Instead, a detachable body could give the sea slug a drastic, but effective, way of dealing with parasites. In a batch of wild-caught E. atroviridis sea slugs, the few that ditched their bodies were parasitized by copepods. So were those that just lost pieces of their body, some of which also regrew.

    On close inspection, the researchers found that sea slugs have a slight groove looped on the back of the head region that seems to work as a break-here zone. The bodies left behind can still move on their own for days or even months. An abandoned body, however, doesn’t regrow its head. The leaf-shaped remnant instead turns pale and weak and eventually dies.

    What might help Elysia slugs manage such extreme regrowth is their ability to steal the tiny green sunlight-trapping energy factories called chloroplasts from plants, the researchers muse. Very young slugs don’t have any chloroplasts. “They need to pierce the cell walls of sea algae and sip the contents,” Yusa says. The grazing slugs can keep the chloroplasts alive for weeks or months.

    Biologists debate what the stolen chloroplasts do for their kidnappers besides provide a pretty, green tinge. Yusa, however, has linked the looted chloroplasts to such consequential matters as improved reproduction. If chloroplasts are more than cosmetic, maybe that energy boost is just what a severed head needs to get (more than) ahead.

    Animal farm:

    Rancher guards irradiated cattle near Fukushima
    https://sports.yahoo.com/rancher-gua...072047126.html

    The cows raised in Japan's Ranch of Hope can never be sold.

    They live just miles away from what was once the Fukushima nuclear station, the site of the world's worst nuclear disaster since Chernobyl.

    In its wake, Japan's government ordered a widespread cull of livestock exposed to radiation.


    But for the past decade, rancher Masami Yoshizawa defied that order, and kept his cows alive.


    "I've been exposed to radiation, but I chose to stay here. By keeping these cattle, I'm hoping for a world without nuclear power plants."

    Hundreds of thousands of people were forced to leave their homes a decade ago following the disaster.

    Many cows starved to death as a result.


    But Yoshizawa stayed - and took in animals left behind.


    Now he guards more than 200 cattle as protest against the government and Tokyo Electric Power, or Tepco, which owned the Fukushima nuclear plant.


    "I hope that more people see these cattle stay alive for a long time - as a memorial of the disaster, and as a symbol of anti-nuclear power."


    Yoshizawa says it costs about USD$74,000 a year to feed them.
    That mostly comes from donations.

    He even drives a bulldozer every day to pick up rotting vegetables from supermarkets, and food waste from factories to feed his cows at a lower cost.

    While he's received compensation from the disaster, he is also critical of what Tepco has contributed to local residents.


    And every month, he takes his protest straight to the utility company's doors.


    Yoshizawa says he's probably the only rancher taking care of the affected cattle.


    But he also says he isn't slowing down, any time soon.

    seafood fraud happening on a vast global scale
    https://www.theguardian.com/environment/2021/mar/15/revealed-seafood-happening-on-a-vast-global-scale

    Many of the studies used relatively new DNA analysis techniques. In one comparison of sales of fish labelled “snapper” by fishmongers, supermarkets and restaurants in Canada, the US, the UK, Singapore, Australia and New Zealand, researchers found mislabelling in about 40% of fish tested. The UK and Canada had the highest rates of mislabelling in that study, at 55%, followed by the US at 38%.

    Sometimes the fish were labelled as different species in the same family. In Germany, for example, 48% of tested samples purporting to be king scallops were in fact the less coveted Japanese scallop. Of 130 shark fillets bought from Italian fish markets and fishmongers, researchers found a 45% mislabelling rate, with cheaper and unpopular species of shark standing in for those most prized by Italian consumers.

    Still other samples proved to be not entirely of aquatic species,with prawn balls sold in Singapore frequently found to contain pork and not a trace of prawn.

    The highest restaurant mislabelling rates – ranging from 40% to 50% – were in Spain, Iceland, Finland and Germany. Fish such as dusky grouper (“mero”) and butterfish were among the species most frequently mislabelled, while for pike perch, sole, bluefin and yellowfin tuna, there was a 50% chance customers did not get what they had ordered.

    Sometimes fish are substituted with similar species – one type of tuna for another, for example. Often, however, the replacement is an entirely different species. A very common stand-in is little known and inexpensive shark catfish, or pangasius. This group of fish is widely farmed in Vietnam and Cambodia, and has a similar taste and texture to other whitefish, such as cod, sole and haddock.
