The idea of scientists bringing pre-historic creatures back to life with some clever DNA trickery might sound familiar to fans of the 1993 Hollywood blockbuster Jurassic Park.

But for Colossal Biosciences – a company that hopes to reintroduce extinct species such as the dodo and the mammoth – it is more than just a film script.

It’s a reality – and one that could be just years away.

“We’ve got all the technology we need,” says Ben Lamm, chief executive of the firm, based in Dallas, Texas.

“It is just a focus of time and funding. But we are 100% confident [we can bring back] the Tasmanian tiger, the dodo, and the mammoth.”

The science behind the project is simple: Work out the genes that make an extinct animal what it is, and then replicate those genes using the DNA of a close existing relative.

“It’s almost reverse Jurassic Park,” says Mr Lamm, speaking to Sky News.

“In the film, they were filling in the holes in the dinosaur DNA with frog DNA.

“We are leveraging artificial intelligence and other tools to identify the core genes that make a mammoth a mammoth and then engineering them into elephant genomes.”

That is the technical part.

But there are some other practical hurdles for Colossal to overcome, namely how, once you have mammoth cells, do you birth a real-life mammoth?

The answer, according to Colossal, is in the womb of an Asian elephant.

But it is a process that could take nearly two years, even after they have worked out how to do it.

“[Each of the] different projects [the mammoth, dodo, and Tasmanian tiger] have different challenges – the mammoth is really around gestation – which is around 22 months,” says Mr Lamm.

“The dodo gestation is pretty great – we are using surrogate chickens. The hardest part is cultivating the primordial germ cells.”

‘Feeling good about 2028’

So after around 4,000 years of extinction, when could we see the return of the mighty mammoth – a creature that fell victim to human hunting and the changing conditions brought about by the end of the last Ice Age.

“We are well into the editing phase,” says Mr Lamm.

“We don’t have mammoths yet, but we still feel very good about 2028.”

Away from the lab, led by Eriona Hysolli, Colossal’s head of biological sciences, there are other issues to overcome – including where the newly returned species will live once they are born.

Mr Lamm says the company is already working with local governments, conservation groups, indigenous people groups, private land lowers, and the public at large, to prepare for the animals to be returned to their natural habitat.

“Our ultimate goal is to put all the animals we make back into the wild,” he says.

‘New tools in the fight’ to protect nature

Colossal says the work is not just about rewilding animals previously lost to the world.

The company is currently working with Dr Paul Ling at Baylor College of Medicine in Houston, Texas, to create a vaccine to eradicate the deadly EEHV virus – which kills around 20% of baby elephants each year.

It is also working closely with the University of Alaska and the University of Stockholm on radiocarbon dating of American mammoths as well as sequencing their genome – the largest study of its type ever undertaken.

Mr Lamm also hopes that, through Colossal’s research, the company can tackle issues facing the world today, including a drop in biodiversity.

“I think we have a duty to this planet that we’ve been given – we are tending towards a loss of up to 50% biodiversity if we don’t do anything,” he says.

“Modern conservation is great, but we need new tools in the fight.

“Work on de-extinction goes hand-in-hand with species preservation, and if Colossal makes a couple of technologies, then maybe it will provide those tools.”

‘Jurassic Park helps people understand our work’

As for the Jurassic Park comparisons, well, there is one small issue, according to Mr Lamm.

In the Steven Spielberg-directed epic, the scientists use DNA embedded in fossilised mosquitoes in amber combined with frog DNA to bring dinosaurs back to life.

“Amber is not a good holder of DNA,” Mr Lamm says.

“But it’s a very entertaining movie and I think Jurassic Park made a lot of people interested in science. I saw it when I was younger and I was like: ‘Wow genetics is cool’.

“It did a lot to explain to the masses that genetic engineering is a thing and something that can be used in powerful ways, and I do think more people understand Colossal because of that.”

The company is also working on a film of its own, and, luckily for everyone, it’s not a dystopian thriller like Jurassic Park.

It has teamed up with award-winning director James Reed, a specialist in nature films, to document its “de-extinction” work.

“It’s really exciting. When you are doing anything bold, it is important to communicate and be transparent, and there’s nothing more transparent than having cameras around all the time,” says Mr Lamm.

Donald Trump announces 30% tariff on imports from EU

Donald Trump announces 30% tariff on imports from EU

Donald Trump has announced he will impose a 30% tariff on imports from the European Union from 1 August.

The tariffs could make everything from French cheese and Italian leather goods to German electronics and Spanish pharmaceuticals more expensive in the US.

Mr Trump has also imposed a 30% tariff on goods from Mexico, according to a post from his Truth Social account.

Announcing the moves in separate letters on the account, the president said the US trade deficit was a national security threat.

In his letter to the EU, he wrote: “We have had years to discuss our trading relationship with The European Union, and we have concluded we must move away from these long-term, large, and persistent, trade Deficits, engendered by your tariff, and non-Tariff, policies, and trade barriers.

“Our relationship has been, unfortunately, far from reciprocal.”

In his letter to Mexico, Mr Trump said he did not think the country had done enough to stop the US from turning into a “narco-trafficking playground”.

The president of the European Commission, Ursula von der Leyen, said today that the EU could adopt “proportionate countermeasures” if the US proceeds with imposing the 30% tariff.

Ms von der Leyen, who heads the EU’s executive arm, said in a statement that the bloc remained ready “to continue working towards an agreement by Aug 1”.

“Few economies in the world match the European Union’s level of openness and adherence to fair trading practices,” she continued.

“We will take all necessary steps to safeguard EU interests, including the adoption of proportionate countermeasures if required.”

Ms von der Leyen has also said imposing tariffs on EU exports would “disrupt essential transatlantic supply chains”.

Meanwhile, Dutch Prime Minister Dick Schoof said on the X social media platform that Mr Trump’s announcement was “very concerning and not the way forward”.

He added: “The European Commission can count on our full support. As the EU we must remain united and resolute in pursuing an outcome with the United States that is mutually beneficial.”

Mexico’s economy ministry said a bilateral working group aims to reach an alternative to the 30% US tariffs before they are due to take effect.

The country was informed by the US that it would receive a letter about the tariffs, the ministry’s statement said, adding that Mexico was negotiating.

How ‘liberation day’ unfolded

Trump’s tariff threats and delays

On his so-called “liberation day” in April, Mr Trump unleashed “reciprocal tariffs” on many of America’s trade partners.

The US president said he was targeting countries with which America has a trade imbalance.

However, since then he’s backed down in a spiralling tit-for-tat tariff face-off with China, and struck a deal with the UK.

The US imposed a 20% tariff on imported goods from the EU in April but it was later paused and the bloc has since been paying a baseline tariff of 10% on goods it exports to the US.

In May, while the US and EU where holding trade negotiations, Mr Trump threated to impose a 50% tariff on the bloc as talks didn’t progress as he would have liked.

However, he later announced he was delaying the imposition of that tariff while negotiations over a trade deal took place.

As of earlier this week, the EU’s executive commission, which handles trade issues for the bloc’s 27-member nations, said its leaders were still hoping to strike a trade deal with the Trump administration.

Without one, the EU said it was prepared to retaliate with tariffs on hundreds of American products, ranging from beef and auto parts to beer and Boeing airplanes.

Donald Trump plans to hit Canada with new tariff – while warning of blanket hike for other countries

Donald Trump plans to hit Canada with new tariff - while warning of blanket hike for other countries

Donald Trump has said he plans to hit Canada with a 35% tariff on imported goods, as he warned of a blanket 15 or 20% hike for most other countries.

In a letter to Canadian Prime Minister Mark Carney, the US president wrote: “I must mention that the flow of Fentanyl is hardly the only challenge we have with Canada, which has many Tariff, and Non-Tariff, Policies and Trade Barriers.”

Mr Trump’s tariffs were allegedly an effort to get Canada to crack down on fentanyl smuggling, and the US president has expressed frustration with Canada’s trade deficit with the US.

In a statement Mr Carney said: “Throughout the current trade negotiations with the United States, the Canadian government has steadfastly defended our workers and businesses. We will continue to do so as we work towards the revised deadline of August 1.”

He added: “Canada has made vital progress to stop the scourge of fentanyl in North America. We are committed to continuing to work with the United States to save lives and protect communities in both our countries.”

Mr Trump has sent a series of tariff letters to 23 countries so far, including one putting a 50% tariff on Brazil in part for the ongoing trial of its former president Jair Bolsonaro for trying to stay in office after he lost the election in 2022.

Mr Trump was similarly indicted for his efforts to overturn his election loss in 2020.

The higher rates would go into effect on 1 August.

Shortly after Mr Trump unveiled his “Liberation Day” tariffs on 2 April, there was a huge sell-off on the financial markets. The US president later announced a 90-day negotiating period, during which a 10% baseline tariff would be charged on most imported goods.

But in an interview with Sky News’s partner network NBC News, Mr Trump said he plans to impose higher blanket tariffs on most US trade partners.

“We’re just going to say all of the remaining countries are going to pay, whether it’s 20% or 15%. We’ll work that out now,” he said.

He added: “I think the tariffs have been very well-received. The stock market hit a new high today.”

The US and UK signed a trade deal in June, with the US president calling it “a fair deal for both” and saying it will “produce a lot of jobs, a lot of income”.

Sir Keir Starmer said the document “implements” the deal to cut tariffs on cars and aerospace, adding: “So this is a very good day for both of our countries – a real sign of strength.”

The US president also teased a “major statement” he will make on Russia over its war with Ukraine.

“I’m disappointed in Russia, but we’ll see what happens over the next couple of weeks,” he said.

“I think I’ll have a major statement to make on Russia on Monday.”

Palestinian activist detained by ICE suing Trump administration for m

A Palestinian activist who was detained for over three months in a US immigration jail after protesting against Israel is suing Donald Trump’s administration for $20m (£15m) in damages.

Lawyers for Mahmoud Khalil have filed a claim against the administration alleging he was falsely imprisoned, maliciously prosecuted and smeared as an antisemite as the government sought to deport him over his role in campus protests.

The 30-year-old graduate student at Columbia University told Sky News’s lead world presenter Yalda Hakim being detained by ICE agents in March “felt like kidnapping”.

He described “plain-clothed agents and unmarked cars” taking him “from one place to another, expecting you just to follow orders and shackled all the time”, which he said was “really scary”.

Mr Khalil said he was not presented with an arrest warrant and wasn’t told where he was being taken.

He said the detention centre he was taken to was “as far from humane as it could be” and “a place where you have no rights whatsoever”.

“You share a dorm with over 70 men with no privacy, with lights on all the time, with really terrible food. You’re basically being dehumanised at every opportunity. It’s a black hole,” he added.

Mr Khalil said he would also accept an official apology from the Trump administration.

The Trump administration celebrated Mr Khalil’s arrest, promising to deport him and others whose protests against Israel it declared were “pro-terrorist, antisemitic, anti-American activity”.

Mr Khalil said after around 36 hours in captivity he was allowed to speak to his wife, who was pregnant at the time.

“These were very scary hours, I did not know what was happening on the outside. I did not know that my wife was safe,” he said.

‘Absolutely absurd allegations’

Mr Khalil said administration officials had made “absolutely absurd allegations” by saying he as involved in antisemitic activities and supporting Hamas.

“They are weaponising antisemitism, weaponising anti-terrorism in order to stifle speech,” he said. “What I was engaged in is simply opposing a genocide, opposing war crimes, opposing Columbia University’s complicity in the war on Gaza.”

A State Department spokesperson said its actions toward Mr Khalil were fully supported by the law.

Asked about missing the birth of his son while he was in prison, Mr Khalil said: “I don’t think there’s any word that can describe the agony and the sadness that I went through, to be deprived from such a divine moment, from a moment that my wife and I had always dreamed about.”

Meanwhile, the deportation case against Mr Khalil is continuing to wind its way through the immigration court system.
