Resurrect the mammoths in the lab to stop the thaw. Have you met Colossal? – Technology



ambition Colossal Biosciences they fit the name of a North American startup that is working to reverse the extinction of species we’re used to seeing in books, movies and museums.

This was announced by the CEO of the company Ben Lamm. To express that the goal is to edit the cells of Asian elephants, which have 99.6% of the woolly mammoth genome, so that they acquire similar characteristics to those of the extinct animal. Then take this hybrid species to the Arctic, restoring its ecosystem and stopping the melting of the permafrost.

According to him: “It is estimated that by 2050 we will lose up to 50% of all biodiversity if we do nothing. But now we have genetic tools that enable us to better ensure species conservation and even “extinction”. The return of the woolly mammoth serves three main purposes: to make progress in editing genes that can be used to preserve the species, treat the diseases that threaten them, and human health; develop technologies for ectopic pregnancy, such as artificial wombs, and recreate the degraded ecosystem of the Arctic by reintroducing some of the megafauna that lived there to delay the melting of permafrost.”

Permafrost is a year-round permafrost covering about 25% of the earth’s surface in the Northern Hemisphere, mainly in Russia, Canada and Alaska. Consisting of small pieces of ice or large masses of ice, it can reach several meters or hundreds. Permafrost is also one of the largest natural reservoirs of carbon dioxide and methane. However, global warming is causing the ice to melt and release these greenhouse gases into the atmosphere.

What’s with the woolly mammoth? It is believed that by thinning out the moss that covered the Siberian tundra and cutting down small trees, they could keep the ground cool and delay or even stop the thaw. “It will take several thousand to influence the supply of carbon,” the CEO of Colossal tells the weekly.

When it comes to pregnancy, Colossal is first thinking about using surrogate bellies – elephants – and then even creating artificial wombs.

Why stop at the mammoth?

“Looking at this project as a whole, we are developing new technologies that, in combination with existing ones, can become a means of “recovering extinction” for species, whether it be a woolly mammoth or a white rhinoceros. north,” says Ben Lamm.

Despite the enthusiasm of the CEO of Colossal BioSciences, this project raises several ethical and practical questions. It remains to be proven that the return of mammoths to Siberia had the intended consequences, which then raises the question of whether it is legitimate to implant embryos of one species into the uterus of another. And these are far from the only questions on the table.

However, the startup, created in 2021, has already managed to raise $75 million for this project.

The Russian army announced the destruction of 45,000 tons of Ukrainian weapons sent by NATO



“In the city of Voznesensk, Mykolaiv region, an arsenal was destroyed, which stored 45,000 tons of ammunition supplied to the Ukrainian army by NATO,” said Russian Defense Ministry spokesman Igor Konashenkov, quoted by EFE.

According to the Russian authorities, the country’s aviation inflicted more than 300 casualties among Ukrainian defenders.

“Consequences of the attack of the Russian Air Force on the temporary deployment of units of the 72nd mechanized brigade in an agricultural company in the city of Artemovsk (Russian name Baimut, in Donetsk) numbering up to 130 military personnel and eight pieces of equipment and armored vehicles. were destroyed,” Konashenkov said.

He added that “after a strike with high-precision missiles” on the 95th Airborne Assault Brigade of the Armed Forces of Ukraine in the city of Dzerzhinsk (Toretsk, in Russian, in Donetsk), up to 70 servicemen were destroyed, three artillery pieces and three vehicles were destroyed.

The Ministry of Defense also added that in the Yarkovsky district in eastern Ukraine, the Russian Air Force shot down more than 100 personnel of the 3rd brigade of the National Guard of Ukraine on the territory of a thermal power plant.

“Due to heavy losses, the Zelensky regime [presidente ucraniano] is taking steps to strengthen troops in the Donbass,” Konashenkov said.

According to a Russian official, this forced the Ukrainian authorities to send newly mobilized civilians to the front, who made their debut as part of the 72nd mechanized brigade in the city of Bila Tserkva, south of Kyiv.

Monkeypox: national tourist was the first case identified in the Azores and traveled to Porto before lockdown ends – News



The Regional Health Authority said in a statement that “the case was discovered in the municipality of Ponta Delgada on the island of San Miguel and the local health delegation immediately took all the procedures indicated in this context.”

The man claimed to have had “contact in Ponta Delgada, with family members and with his partner residing in San Miguel (tested negative in the last few hours)”, with the Ponta Delgada Health Delegation “determining home isolation” in both cases and physical distancing from other people until all injuries are healed.”

“The person who tested positive was notified of the result on Friday evening, but reported that he had already traveled, also on Friday, from Ponta Delgada to Porto, from where he would soon return to Paris, the city where he officially lives and works. “, – reports the regional health authority, adding that the man has been in San Miguel since July 26.

The regional health authority notified the national authorities of the case so that they could follow it up in the north of the country.

The number of confirmed cases of monkeypox virus infection in Portugal has risen to 710, of which 77 were detected in the last week, the Directorate General of Health (DGS) said.

All regions of continental Portugal and the autonomous region of Madeira reported cases of human infection with monkeypox virus, of which 509 (82.5%) were in the Sanitary Region of Lisbon and Vale do Tejo.

Of the many cases reported to the Epidemiological Surveillance System, the majority are in the 30 to 39 age group and are male, according to the DGS, with four female cases now, two more than a week old.

Ukraine: UN agency ‘extremely concerned’ about risk of ‘nuclear holocaust’ – Newsroom



“I am extremely concerned about yesterday’s explosions [sexta-feira] the largest nuclear power plant in Europe, highlighting the very real risk of a nuclear catastrophe that threatens public health and the environment in Ukraine and beyond,” Grossi warned in a statement released in Vienna, believing that “we are playing with fire.”

Moscow and Kyiv today accused each other of compromising the safety of Europe’s largest Zaporskaya nuclear power plant.

Grossi recalled that, according to the Ukrainian authorities, there was no damage to the reactors and no radiation release, but there were damages to other parts of the nuclear power plant.

The head of the UN nuclear energy agency considered endangering a nuclear power plant “completely unacceptable” and argued that military strikes against it were “playing with fire” and could have “potentially catastrophic consequences.”

“I strongly and urge all parties to provide maximum deterrence in the vicinity of this critical six-reactor nuclear facility,” he wrote.

Grossi again offered the IAEA the opportunity to conduct an on-site verification and “prevent the situation from getting further out of control.”

In June, the IAEA director expressed his readiness to visit the Russian-controlled plant, but Ukraine sharply criticized these plans, saying that the trip of the Argentine UN representative could be interpreted as legitimizing the Russian occupation.

The diplomat insisted that the mission was “decisive” to stabilize the situation at the nuclear power plant.

President of Ukraine Volodymyr Zelensky, through a video message, accused Russia of “recreating an extremely dangerous situation for the whole of Europe”: “they bombed the Zaporskaya nuclear power plant twice.”

Moscow, which has controlled the facility almost since the early days of its military campaign in Ukraine, disputed the claims, calling Kyiv, for its part, a promoter of “nuclear terrorism.”

“Ukraine’s attacks on nuclear facilities can be qualified under international law as acts of nuclear terrorism,” Russian Senator Konstantin Kosachev said on the Telegram social network.

Pro-Russian authorities in the Zaporizhia region, partly occupied by the Russian army, yesterday accused Ukrainian forces of shelling the nuclear power plant and damaging power lines and industrial buildings at the plant.

The attack led to the closure of one of the nuclear units after a power outage.
