Colossal Biosciences' female ‘dire wolf' meets her brothers for first time
In April, the biology research company announced the birth of the wolves after using DNA extracted from two fossils as well as 20 edits of the genetic code of a grey wolf — similar to a technique used in the movie Jurassic Park, where dinosaurs are brought back to life by using frog DNA to fill in genetic gaps.
On Tuesday, they brought the two males, Romulus and Remus, together in one habitat with the one female, Khaleesi, to watch them meet for the first time during separate interactions.
In a video shared to the company's YouTube channel, Khaleesi met her brothers individually, beginning with an introduction to Romulus.
Romulus was brought into a grass yard before Khaleesi entered and ran towards a stack of logs, crawling under while her brother began chasing her.

'Everybody was showing great behaviours and ended up being comfortable,' a Colossal handler explained in the video. 'She smelled him and he smelled her. Then she took off running and he, of course, ran with her.'
They said Khaleesi is small enough to go underneath the logs but Romulus is larger. This helped the female wolf control the interaction.
'Everything was going great and we wanted to make sure she got a chance to meet Remus today so we went ahead and shifted Romulus back in and we let Remus out,' the trainer added. 'They were both excited. Everybody was so good and played but Remus is almost more gentle than Romulus.'

As they observed the wolves, they said the siblings were showing 'lots of play behaviours' and kept their ears up and wagged their tails during their first interaction.
'Once we really see her being in control and confident and she might be a little bit bigger, then we'll decide when the best time is to put them all three together again and see how that goes,' the handler said.

'We care a lot about these animals and we want to make sure that nobody gets injured, no one is scared. All of those processes and thoughts and needs are being addressed and the team is constantly reassessing.'
Romulus, Remus and Khaleesi are being raised in an undisclosed nature preserve and Colossal has 10 full-time animal care staff to support the wolves' physical and mental well-being.

The preserve where the trio lives is on 2,000-plus acres enclosed by 10-foot-tall, zoo-grade fencing with redundant perimeter security. The wolves are monitored through on-site live camera, security personnel and drone tracking to ensure their safety and welfare.
The preserve also includes a smaller, six-acre secure site where the wolves can be further tended to and studied. The smaller area also supports an on-site veterinary clinic, a wolf management facility, an outdoor storm shelter and natural-built dens for the wolves.
While dire wolves had previously been extinct for more than 12,500 years, many experts claim that Colossal Biosciences' creation is considered to be genetically modified grey wolves.
'Those slight modifications seemed to have been derived from retrieved dire wolf material. Does that make it a dire wolf? No,' Corey Bradshaw, professor of global ecology at Flinders University, previously told Global News.

'When you claim all these great, big things and you don't provide the associated evidence, especially in something as controversial as this, that is a massive red flag.'

'Living clickbait': Experts dispute dire wolf de-extinction claim
Dolf DeJong, Toronto Zoo CEO, told Global National that the news of the so-called dire wolves was a case of 'living clickbait.'
He added that it was 'rich multimillionaires creating animal GMOs for self-interest' and called the creation 'really, really troubling.'
Filmmaker Peter Jackson and Game of Thrones creator George R.R. Martin collaborated with Colossal for the reveal of the wolves in April by lending the company the official 330-pound Iron Throne prop that was used to promote the hit series, Game of Thrones.
'Many people view dire wolves as mythical creatures that only exist in a fantasy world, but in reality, they have a rich history of contributing to the American ecosystem,' Martin said in a statement. 'I get the luxury to write about magic, but Ben and Colossal have created magic by bringing these majestic beasts back to our world.'

Quiet ‘Quinzou' offers inclusive Acadian Day celebrations for neurodivergent people
Marie-Pier Leroux is proud of her Acadian heritage, but has found traditional Acadian Day celebrations overwhelming as an autistic woman. She says other neurodivergent people have told her that traditional Acadian Day celebrations, which are often large public gatherings involving loud music, can feel daunting. 'It's either the lights, the noise, and people are hugging each other. People are so happy with this celebration, but (the idea) came to me that maybe we should have something more sensory-friendly for other neurodivergent people that want to celebrate,' she said in an interview. Leroux is a social worker and works as a project assistant at the non-profit Autism Resource Centre in Riverview, N.B. On Friday, her organization held its first Acadian Day, or Quinzou as it's sometimes called in French, specifically adapted for those with sensory issues. Story continues below advertisement 'It's very much just a safe space for people to hang out where the lights will be dimmed and the music won't be too loud and people won't be making as much noise,' Leroux said. Get weekly health news Receive the latest medical news and health information delivered to you every Sunday.

Participants were asked to sign up in advance to keep the event small. Leroux had seven participants sign up for her event in Riverview, N.B., but said she received inquiries from across the province asking if similar events were being held in other communities. 'Whatever heritage that you got, I think it's important to celebrate it because it's part of who you are. The Acadians have been through so much that it deserves to be celebrated, and it deserves to be a safe space for everybody,' she said. Neurodivergent Acadian artist Céleste Godin is kicking off the tintamarre, an Acadian tradition where people march down the street making noise, in Moncton on Friday, as well as hosting the evening celebrations. It's a modern tradition meant to mark the fact that the Acadian people are still present and thriving. 'The tintamarre is a super sensory intense environment, it's really loud there's hugs every where there's noise everywhere, so it can be overwhelming sensory wise,' they said. Story continues below advertisement They're pleased to hear about Leroux's initiative and use their own techniques to adapt celebrations to their sensory issues. 'Something I do, instead of a noise maker, I'll do a visual thing. I'll bring a fan or blow some bubbles, and that way it's a little less loud in my little bubble,' they said. Marie-Julie Bourque, who is co-ordinating Acadie Rock, Moncton's Acadian Festival, said the organizers are considering offering sensory aids like earplugs and headphones at future events.

Why rabbits with strange-looking ‘horns' are hopping around Colorado
Rabbits have been spotted hopping around a Colorado town with unusual horn-like growths poking out of their heads, causing alarm among some locals. The bunnies seen in Fort Collins, a town about 105 kilometres north of Denver, are infected with the somewhat common Shope papillomavirus, which causes wart-like tumours that metastasize from their faces, appearing like horns. View image in full screen Rabbit with the papilloma virus (CRPV), or Shope papilloma virus. It infects rabbits, causing keratinous carcinomas, typically on or near the animal's head. Education Images/ Getty Images Photos shared online of the infected Cottontails have led to the species being given some unfortunate epithets, including 'Frankenstein bunnies,' 'demon rabbits' and 'zombie rabbits.' However, their disease is well known to scientists and has been extensively studied. Story continues below advertisement Kara Van Hoose, a spokesperson for Colorado Parks and Wildlife, told the Associated Press on Wednesday that the agency had received reports of sightings in Fort Collins.

The growths often look like warts but can appear more like horns if they grow longer, Van Hoose explained, assuring that they are harmless to rabbits unless they grow on their eyes or mouths and interfere with eating. Rabbits' immune systems can fight the virus and, once they do, the growths will disappear, she said. The virus was named after Dr. Richard E. Shope, a professor at The Rockefeller University who discovered the disease in Cottontails in the 1930s. Infected rabbits' appearance is said to have influenced the centuries-old jackalope myth in North America, which told of a rabbit with antlers or horns, among other animal variations. The disease in rabbits also contributed to scientists' knowledge about the connection between viruses and cancer, such as the human papillomavirus that causes cervical cancer. — with files from The Associated Press Story continues below advertisement

The Ongoing History of New Music, encore presentation: Rivers Cuomo and Weezer, Alt-Rock's Nerd Heroes, part 2
The way I see it, there are three types of bands that stretch across a spectrum. First, there's the extreme sort, a group that will do almost anything to attract attention…you're probably thinking of some names right now. Next to them are the traditional sort, and they comprise the vast majority of bands out there. These are groups that go out there, do their thing earnestly and honestly, and hope that this will be enough for music lovers. They occupy a huge part of this spectrum. And then we have the third type: the quirky, eccentric, and weird. These groups come in all sorts of flavours, from mildly bent to the gloriously stupid and the confoundingly weird. These bands go a long way into making music fun and unpredictable. Not all land with audiences—they're too strange, not enough people get the joke, or maybe they're just in the wrong place at the wrong time. Story continues below advertisement But there can be a balance between being quirky and fun and having songs that have widespread appeal. They have just enough of the nerd factor to set themselves apart while not being so nerdy that they'll turn too many people off.

It takes songwriting skills, careful management of your image, and plenty of creativity and imagination, especially if you want to main things over more than just a couple of albums and touring cycles. Among the very, very, very best of this class of band is Weezer. They've perfected a formula that includes musical talent, wit, self-deprecation, left-of-centre thinking, a desire to have fun, a willingness to experiment, some clever marketing, and above all, to let their fans in on everything. It's an approach that has worked very, very well for decades. This is part two of Rivers Cuomo and Weezer: Alt-Rock's Nerd Heroes, Part 2. And, of course, the playlist from Eric Wilhite.
