Every Sumatran rhino has died in Malaysia. Scientists want to bring them back with cloning technology

Now, Malaysian researchers are hoping to use tissues and cells from Iman and other useless rhinos to bring the population again.

The project, executed by a group at the Worldwide Islamic College Malaysia (IIUM), focuses on stem cell engineering and in-vitro fertilization. The process is equivalent to cloning technological know-how, in that it aims to give start to a new newborn applying cells from previous rhinos, stated Dr. Muhammad Lokman Bin Md. Isa, just one of the lead researchers.

“Before the three rhinos (the previous survivors in Malaysia) died, we received their cells, and the cells are however alive — which is why I’m pretty assured,” Dr. Lokman advised CNN. “If you you should not have any cells, or if we just experienced tissue that usually are not residing any longer, we can not do nearly anything with that. We can only set it in a e book or museum. But now we have a living thing that we can use.”

This is how the process is effective: In collaboration with the Borneo Rhino Alliance (BORA), the scientists gathered cells and tissue from the last three Sumatran rhinos at BORA’s sanctuary — such as Iman — right before every single died.

The cells arrived from the rhinos’ hearts, lungs, brains and kidneys. Crucially, the staff gathered stem cells — fundamentally, raw materials from which cells with specialized functions can be created.

There are then two possible strategies. The very first is to acquire these stem cells into an egg and sperm, to develop an embryo that will be implanted into a surrogate mother. The surrogate will possible be a further rhino, either a Sumatran rhino from yet another region or another species.

The second technique is to acquire the egg of a surrogate animal, take away the nucleus, and join it with a Sumatran rhino’s somatic mobile. This approach was famously made use of to clone Dolly the sheep in 1996.

Lokman and his colleagues are seeking equally means.

For the reason that the stem cells self-replicate, the group has a decent stockpile and can check out various solutions to see which performs greatest.

There are 2 northern white rhinos left worldwide. Scientists created embryos to save the animal from extinction

The team is still in the preliminary levels upcoming, they need to analyze the cells to produce a genomic database, differentiate the stem cells, and do the job with zoos and conservancies to come across a suitable surrogate woman. There are a range of techniques this could go incorrect the fertilization could are unsuccessful, and even if it isn’t going to, the being pregnant could fail after the embryo is implanted.

But there are indicators of hope from comparable jobs all around the globe. A Kenyan conservancy residences the only two northern white rhinos left globally, Fatu and Najin, who are both of those female. Last yr, scientists effectively fertilized in-vitro embryos gathered from the two remaining women with sperm from useless males, which was celebrated as a important action ahead in preserving the subspecies.

The race against extinction

Iman died at BORA’s Borneo Rhino Sanctuary final yr, the place she had been saved and cared for considering the fact that her seize in 2014. She was 25, and had cancer, which was beginning to result in her discomfort for the reason that a tumor was placing tension on her bladder.

Her dying came months immediately after Tam, Malaysia’s last male Sumatran rhino, died after suffering organ failure. Conservationists had hoped to breed Tam and Iman.
Tam was the only male Sumatran rhino left in Malaysia before he died in 2019.

There are a variety of things that challenging these attempts the female rhinos at the reserve turned out to be infertile, and plans to established up an worldwide breeding collaboration in the long run failed thanks to “a sequence of incidents, some sociopolitical, some organic, and some only bad luck,” stated Susie Ellis, govt director of the International Rhino Foundation, in a statement soon after Tam’s loss of life.

Sumatran rhinos, the world’s smallest rhino species, are listed as critically endangered by the World Wildlife Fund. The Intercontinental Rhino Foundation estimates that there are less than 80 alive in the planet.

With Iman’s loss of life, the IRF declared the species extinct in the wild in Malaysia the remaining rhinos are scattered throughout Indonesia and Thailand.

Scientists create fake rhino horn from horsehair in a bid to save the species

The population’s decline was originally caused by poaching for their horns, which were being coveted as ingredients in traditional Asian medicine. Later, it was exacerbated by fragmented habitats and human encroachment on the surroundings, which protect against the rhinos from accumulating and breeding.

The intercontinental trade in rhino horn has been banned considering the fact that 1977, controlled by the Convention on Global Trade of Endangered Species of Wild Fauna and Flora (CITES), but person countries ascertain their own legal guidelines that allow or prohibit its sale domestically, according to Preserve the Rhino.

There are now only five remaining rhino species globally, and all are threatened. Some sub-species have previously vanished the western black rhino, native to western Africa, was declared extinct in 2013 because of to poaching. The past male northern white rhino died final yr, which is what pushed experts to check out in-vitro fertilization with Fatu and Najin.

Vladimir Putin has delayed the invasion of Ukraine at least three times.

Published

on

Putin has repeatedly consulted with Russian Chief of the General Staff Valery Gerasimov and Defense Minister Sergei Shoigu about the invasion, Europa Press told Ukraine’s chief intelligence director Vadim Skibitsky.

According to Skibitsky, it was the Russian Federal Security Service (FSB), which is responsible for counterintelligence and espionage work, that put pressure on Gerasimov and other military agencies to agree to launch an offensive. .

However, according to the Ukrainian intelligence services, the FSB considered that by the end of February sufficient preparations had already been made to guarantee the success of the Russian Armed Forces in a lightning invasion.

However, according to Kyiv, the Russian General Staff provided the Russian troops with supplies and ammunition for only three days, hoping that the offensive would be swift and immediately successful.

The head of Ukrainian intelligence also emphasized the cooperation of local residents, who always provided the Ukrainian authorities with up-to-date information about the Russian army, such as the number of soldiers or the exact location of troops.

The military offensive launched on February 24 by Russia in Ukraine caused at least 6.5 million internally displaced persons and more than 7.8 million refugees to European countries, which is why the UN classifies this migration crisis as the worst in Europe since World War II (1939-1945). gg.). ).

At the moment, 17.7 million Ukrainians are in need of humanitarian assistance, and 9.3 million are in need of food aid and housing.

The UN has presented as confirmed 6,755 civilian deaths and 10,607 wounded since the beginning of the war, stressing that these figures are much lower than the real ones.

Life sentence for former Swedish official for spying for Russia

Published

on

A Stockholm court on Monday sentenced a former Swedish intelligence officer to life in prison for spying for Russia, and his brother to at least 12 years in prison. In what is considered one of the most serious cases in Swedish counterintelligence history, much of the trial took place behind closed doors in the name of national security.

According to the prosecution, it was Russian military intelligence, the GRU, who took advantage of the information provided by the two brothers between 2011 and their arrest at the end of 2021.

Peyman Kia, 42, has held many senior positions in the Swedish security apparatus, including the army and his country’s intelligence services (Säpo). His younger brother, Payam, 35, is accused of “participating in the planning” of the plot and of “managing contacts with Russia and the GRU, including passing on information and receiving financial rewards.”

Both men deny the charges, and their lawyers have demanded an acquittal on charges of “aggravated espionage,” according to the Swedish news agency TT.

The trial coincides with another case of alleged Russian espionage, with the arrest of the Russian-born couple in late November in a suburb of Stockholm by a police team arriving at dawn in a Blackhawk helicopter.

Research website Bellingcat identified them as Sergei Skvortsov and Elena Kulkova. The couple allegedly acted as sleeper agents for Moscow, having moved to Sweden in the late 1990s.

According to Swedish press reports, the couple ran companies specializing in the import and export of electronic components and industrial technology.

The man was again detained at the end of November for “illegal intelligence activities.” His partner, suspected of being an accomplice, has been released but remains under investigation.

According to Swedish authorities, the arrests are not related to the trial of the Kia brothers.

“They can strengthen their positions. We understand that this can happen. At the same time, we do not rule out that they will announce a general mobilization,” Danilov said in an interview with the Ukrainska Pravda online publication.

Danilov believed that this mobilization would also be convened “to exterminate as many as possible” of Russian citizens, so that “they would no longer have any problems on their territory.”

In this sense, Danilov also reminded that Russia has not given up on securing control over Kyiv or the idea of ​​the complete “destruction” of Ukraine. “We have to be ready for anything,” he said.

“I want everyone to understand that [os russos] they have not given up on the idea of ​​destroying our nation. If they don’t have Kyiv in their hands, they won’t have anything in their hands, we must understand this,” continued Danilov, who also did not rule out that a new Russian offensive would come from “Belarus and other territories.” .

As such, Danilov praised the decision of many of its residents who chose to stay in the Ukrainian capital when the war broke out in order to defend the city.

“They expected that there would be panic, that people would run, that there would be nothing to protect Kyiv,” he added, referring to President Volodymyr Zelensky.

The military offensive launched on February 24 by Russia in Ukraine caused at least 6.5 million internally displaced persons and more than 7.8 million refugees to European countries, which is why the UN classifies this migration crisis as the worst in Europe since World War II (1939-1945). gg.). ).

At the moment, 17.7 million Ukrainians are in need of humanitarian assistance, and 9.3 million are in need of food aid and housing.

The Russian invasion, justified by Russian President Vladimir Putin on the need to “denazify” and demilitarize Ukraine for Russia’s security, was condemned by the international community at large, which responded by sending weapons to Ukraine and imposing political and economic sanctions on Russia.

The UN has presented as confirmed 6,755 civilian deaths and 10,607 wounded since the beginning of the war, stressing that these figures are much lower than the real ones.
