Scientists genetically engineer mice with thick hair like the extinct woolly mammoth

Scientists at Colossal Biosciences have developed genetically modified mice with thick hair resembling the woolly mammoth, including longer hair and curly whiskers.
Colossal identified genetic variants that differentiate woolly mammoths from Asian elephants for this project.
The modified mice feature traits that could help test DNA links to the physical traits of the woolly mammoth.
An unpublished scientific paper on the research raises concerns about the mice's cold tolerance, which is crucial for the study's justification.

Ten Surreal Attempts to Bring Species Back from Extinction

In a world of aggressive hunting and rapidly changing ecosystems, more and more species are being wiped out. But does extinction have to be the end? It might sound like something from Jurassic Park, but advances in gene editing and cloning techniques mean scientists could be on the verge of reviving long-gone creatures. Could mammoths, […] The post Ten Surreal Attempts to Bring Species Back from Extinction appeared first on Listverse.

Lara Williams: Woolly mammoths? Mars? Let's take care of what we've got

Last week, science delivered a really cute experimental result. Researchers created a “colossal woolly mouse,” a fluffy rodent that’s purported to be a step on the way to resurrecting woolly mammoths from the age of dinosaurs. But that project —…

The scientific challenges of de-extinction by Dr James Williams

In the realm of scientific innovation, few endeavours capture the imagination quite like the quest to bring extinct species back to life. Among the most iconic of these lost creatures is the woolly mammoth, a symbol of the Ice Age that roamed the Earth thousands of years ago. Recently, the scientific community has made headlines with the creation of a "woolly mouse," a genetically engineered rodent with traits reminiscent of the mammoth. This de…

Colossal says creating woolly mice is a ‘validation step’ for de-extinction and could help eradicate diseases

It was a busy week for Colossal Biosciences: On Tuesday, it introduced the world to the first-ever woolly mice; by Wednesday, those mice were going viral; and on Saturday, they were the topic of a bit on Saturday Night Live’s Weekend Update. The success of genetically engineering these little creatures represented a huge leap toward a bigger goal: bringing back the woolly mammoth. After spending 2.5 years editing mammoth genes, the team applied …

Colossal Biosciences CEO Dissects the $10B Startup’s Effort to Bring Back Extinct Animals

Bringing the woolly mammoth back to life is no easy task. But for Ben Lamm, CEO of Colossal Biosciences, the stress of the job is well worth it for such a breakthrough’s potential impact on conservation, technological advancement and what he thinks will eventually be a lucrative payoff. The biotech aspect, which involves genetically engineering ancient DNA into the closest living relatives of extinct species, is hard enough. “This is making a ma…
