Study: Neanderthal genes may be liability for COVID patients – BarrieToday

Published

 on


BERLIN — Scientists say genes that some people have inherited from their Neanderthal ancestors may increase their likelihood of suffering severe forms of COVID-19.

A study by European scientists published Wednesday by the journal Nature examined a cluster of genes that have been linked to a higher risk of hospitalization and respiratory failure in patients who are infected with the new coronavirus.

Researchers Hugo Zeberg and Svante Paabo determined that the genes belong to a group, or haplotype, which likely came from Neanderthals. The haplotype is found in about 16% of the population in Europe and half the population in South Asia, while in Africa and East Asia it is non-existent.

Modern humans and Neanderthals are known to have interbred at various points in history, resulting in an exchange of genes than can still be found today.

The genes are one of several risk factors for COVID-19, including age, sex and pre-existing conditions like obesity, diabetes and heart problems.

Zeberg and Paabo, who work at the Karolinska Institute in Sweden and the Max Planck Institute for Evolutionary Anthropology in Germany, noted that the prevalence of the particular Neanderthal gene group is highest in people from Bangladesh, where 63% are estimated to carry a copy of the haplotype.

They cited studies from the U.K. showing that people of Bangladeshi descent have about two times higher risk of dying from COVID-19 than the general population.

“It is striking that the genetic heritage from the Neanderthals has such tragic consequences during the current pandemic,” Paabo said in a statement. “Why this is must now be investigated as quickly as possible.”

But Andre Franke, director of the Institute of Clinical Molecular Biology at the University of Kiel, Germany, said the findings have no immediate impact on the treatment of COVID-19.

In a comment ahead of the study’s final publication, Franke said one interesting question arising from the study is why that haploytpe — unlike most Neanderthal genes — survived until today.

“Perhaps it’s good for a very active immune system if one doesn’t have other risk factors,” he suggested.

“Even though we have some work ahead of us to determine the outcome of the event — the successful contact, the TAGSAM gas firing, and back-away from Bennu are major accomplishments for the team. I look forward to analyzing the data to determine the mass of sample collected,” Dante Lauretta said in a statement, according to CNN. Lauretta is the principal investigator for the mission and is a professor at the University of Arizona Lunar and Planetary Laboratory.

Space: Astronauts uncovered a leak at the space station ISS with a tea bag – three are back on earth – Pledge Times

Published

Spacemen of the International Space Station ISS have shown ingenuity. The astronauts made use of a tea bag in space. Three of them have now returned to earth.

  • Russia and the USA share the International space station ISS.
  • However, there is one at the station about 400 kilometers above the earth leak.
  • The crew tried to fix the air leak using a Tea bags to detect.

Update from October 22nd, 4:40 p.m. Three of the astronauts who boarded the International Space Station (ISS) with help of a Tea bags one leak have found (see first report), have returned to Earth safely after almost 200 days on the ISS. The US astronaut Chris Cassidy and the Russian cosmonauts Anatoly Ivanishin and Ivan Wagner landed on Thursday in the Kazakh steppe, as photos by the Russian space agency Roskosmos show.

The three spacemen were in April ISS broken up. Because of the Corona pandemic Wagner, Iwanischin and Cassidy had to be in quarantine a good month before the start of their six-month mission. At that time they could not personally say goodbye to their families. It was the third mission on board the ISS for Cassidy and Ivanishin. Wagner, on the other hand, made his first flight to the space station. In a tweet before his return to earth, the 35-year-old wrote: “Mom, I’m coming home.”

First report from October 19, 2020: Space: Leak found at space station ISS – household goods are the solution

Moscow – spaceman the International Space Station have a possible Air leak with help of a Tea bags tracked down. This had flown in weightlessness in the direction of the leak, said cosmonaut Anatoly Ivanishin according to the state agency Tass. “We have several photos and videos of the direction of flight of the teabag.” He reckons with “actually having found the probable leak”. It should start with a duct tape be sealed.

The space travelers have been occupied with the leak in the station about 400 kilometers above the earth for weeks. They had to spend a weekend in the Russian segment in August because they were looking for the hole in another part of the station. According to earlier information from the Russian space agency Roscosmos the leak is “extremely insignificant” and harmless to the astronauts and cosmonauts.

Space station ISS: “Air pressure continues to drop”

“Of the Air pressure continues to fall, but not as quickly, ”said Ivanishin. The crew now wants to better seal the crack and keep an eye on the situation. “Perhaps we should use the more effective patches from our partners,” said the Russian spaceman, referring to his American colleagues.

A short time later that is Oxygen system Elektron-WM failed according to Roscosmos. A spokesman for Roskosmos confirmed, however, that there is no danger for the crew, as the oxygen system in the US segment of the ISS continues to function normally.

ISS: Russian aerospace veteran: “All modules in the Russian segment are worn out”

Currently hold up six spacemen in the ISS. The crew had only last week Reinforcement got after a Soyuz capsule with three spacemen on board after a flight in Record time has docked with the ISS. So far, there have been three space travelers on the ISS, who were also under strict conditions in the spring corona-Pads started. They are supposed to return to earth in October.

It wasn’t until April Oxygen leak found in the ISS, which is more than two decades old. The Russian aerospace veteran Gennadi Padalka told the Ria-Novosti news agency that the station’s Russian equipment had long exceeded its shelf life: “All modules in the Russian segment are worn“Said the cosmonaut who holds the record for the most days spent in space. The equipment was actually only designed for a service life of 15 years. (ck / dpa)

Most recently, an asteroid named “Bennu” was on a dangerous course towards Earth in space. Even a ninth planet in our solar system is said to have been discovered.

NASA astronaut Chris Cassidy, Russian counterparts return safely to Earth from space station

Published

 on

A trio of space travelers safely returned to Earth on Thursday after a six-month mission on the International Space Station.

The Soyuz MS-16 capsule carrying NASA astronaut Chris Cassidy, and Roscosmos’ Anatoly Ivanishin and Ivan Vagner landed on the steppes of Kazakhstan southeast of the town of Dzhezkazgan at 7:54 a.m. (2:54 GMT) Thursday.

After a brief medical checkup, the three will be taken by helicopters to Dzhezkazgan from where they will depart home.

Cassidy will board a NASA plane back to Houston, while Vagner and Ivanishin will fly home to Star City, Russia.

As part of additional precautions due to the coronavirus, the rescue team members meeting the crew were tested for the virus and the number of people involved in the recovery effort was limited.

Cassidy, Ivanishin and Vagner spent 196 days in orbit, having arrived at the station on April 9. They left behind NASA’s Kate Rubins and Roscosmos’ Sergey Ryzhikov and Sergey Kud-Sverchkov, who arrived at the orbiting outpost a week ago for a six-month stay.

Cassidy, returning from his third space mission, has now spent a total of 378 days in space, the fifth highest among U.S. astronauts.

While serving as the station’s commander, Cassidy welcomed SpaceX Demo-2 crew Robert Behnken and Douglas Hurley, the first NASA astronauts to launch to the space station on an American spacecraft from American soil since the retirement of the space shuttle fleet in 2011.
