Thailand tackles wildlife trade to reduce future pandemic risk
In an effort to reduce the risk of future pandemics, Thai officials say they are stepping up efforts to reduce the wildlife trade.
On Thursday, Natural Resources and Environment Minister Waravut Silpa-archa said the government intends to make Thailand “free from legal wildlife trade” and tackle illegal wildlife trafficking, the Associated press reported.
The COVID-19 pandemic has increased the urgency to shut down the supply chain of wildlife and game meat seen as a key factor in the emergence and spread of COVID-19, Ebola and ‘other diseases, said Silpa-archa and other officials in pre-registered addresses.
The campaign motto is: “Stop disease and extinctions: never eat, buy, hunt or sell wild animals” AP reported.
First Ohio COVID19 Vaccine Lottery Winner Announced
A “whirlwind” is how the first winner of the Ohio COVID-19 vaccination incentive lottery describes learning she had won $ 1 million.
Abbigail Bugenske, 22, was on her way to her family’s home in suburban Cleveland when she got a call from Governor Mike DeWine telling her she had won. A few minutes later, she was in her parents’ house screaming, Associated press reported.
“It has absolutely not been processed yet. I’m still digesting it – and I like to say that I feel like it’s happening to a different person. I can’t believe it,” said Bugenske Thursday morning at a press conference.
The mechanical engineer for GE Aviation in suburban Cincinnati said she had no plans to quit her job. She said she would donate to charities, buy a car, but then invest most of her earnings, the AP reported.
Four more winners of $ 1 million and college scholarships will be announced every Wednesday for the next four weeks as part of the Vax-a-Million Lottery.
The first recipient of a full college scholarship was eighth student Joseph Costello from Englewood near Dayton, the AP reported.
COVID-19 Vaccines May Provide Protection for Years: Studies
COVID-19 vaccines can offer protection for at least a year, or even a lifetime, for people who have previously been exposed to the virus, two new studies suggest.
Both examined people who had been exposed to the coronavirus (SARS-CoV-2) that causes COVID-19 about a year earlier, The New York Times reported.
Cells that remember the virus persist in the bone marrow and can produce antibodies when needed, according to a study published in the journal Nature.
The other study found that these memory B cells continue to mature and strengthen for at least 12 months after the initial infection with the coronavirus. It was posted on the biology research site BioRxiv.
Taken together, the results suggest that most people who recovered from SARS-CoV-2 infection and were later vaccinated Time mentionned.
But it’s likely that people vaccinated who have never been infected will still need booster shots, as will some people who have been infected but have not produced a strong immune response against the virus.
“The articles are consistent with the growing volume of literature which suggests that the immunity elicited by infection and vaccination against SARS-CoV-2 appears to be long lasting,” Scott Hensley, an immunologist at the University of Pennsylvania, who was not involved in the research, told the Time.
The memory B cells produced in response to coronavirus infection and stimulated by vaccines are so powerful that they can fight even variants of the virus, eliminating the need for boosters, according to Michel Nussenzweig, an immunologist at Rockefeller University of New York who led one of the studies.
“People who have been infected and get vaccinated have a really great response, a great set of antibodies, as they keep on evolving their antibodies,” Nussenzweig told the Time. “I expect them to last a long time.”
Scientists say they found cause of rare blood clots linked to certain COVID vaccines
The cause of rare blood clots in some people who have received AstraZeneca and Johnson & Johnson COVID-19 vaccines has been discovered, researchers report.
Vaccines use adenovirus (common cold virus) vectors to transfer vaccine components into cells, but some of the material creeps into the nucleus of cells, which is not an ideal place for the virus to pass. manufactures proteins, explained the German scientists. Washington post reported.
These inferior proteins, some of which can separate inside the body, could trigger blood clots in a small number of people who receive the vaccines, according to the unpaired study published online.
The Russian vaccine against the Sputnik V coronavirus also uses an adenovirus vector, the To post reported.
COVID-19 vaccines that use mRNA technology, including Pfizer and Moderna, work in a different way and “should represent safe products,” according to the study.
Rolf Marschalek, one of the study’s authors, told the Financial Times that the adenovirus vector vaccines can be modified to eliminate the risk of blood clots, and said Johnson & Johnson “is trying to optimize their vaccine now”, To post reported.
Reduced restrictions on the use of embryos in research
An international standard that limits how long human embryos can grow in the laboratory has been extended under limited conditions, which will remove a barrier to stem cell research.
But the International Society for Stem Cell Research did not specify how long embryos could be cultured beyond the 14-day limit specified in the 2016 guidelines, the Associated press reported.
This restriction has blocked research into a crucial period of embryo development, usually between 14 and 28 days, according to Robin Lovell-Badge, a stem cell expert at the Crick Institute in London and chairman of the group that wrote the new guidelines. .
“We believe that many birth defects develop quite early in this period,” said Lovell-Badge, the AP reported. “By better understanding these first steps, it could allow us to adopt simple procedures to reduce the amount of suffering.”
But not everyone is comfortable with the new guidelines, and some fear allowing human embryos to grow at more advanced stages in the lab.
Marcy Darnovsky, executive director of the Center for Genetics and Society, told the AP that it is difficult to find a scientific justification for the new guidelines.
“When an embryo is in a petri dish outside the body, are you really going to be able to say anything meaningful about a miscarriage or embryonic development?” she said.
Darnovsky was also concerned that the guidelines do not place a limit on how long human embryos can grow.
The new guidelines ban human cloning, the transfer of human embryos to an animal uterus and the creation of human-animal chimeras, saying such work “lacks scientific justification or is ethically concerning.”
US intelligence says to ‘redouble’ efforts to determine source of COVID-19
The U.S. intelligence community has been asked to “redouble” its efforts to find out the origins of the COVID-19 pandemic, President Joe Biden said on Wednesday.
The move was prompted by a new report asking if the new coronavirus came from a laboratory in Wuhan, China, according to CBS News.
The intelligence community has 90 days to “collect and analyze information that could bring us closer to a definitive conclusion” on how the pandemic began, Biden said.
“To date, the US intelligence community has ‘coalesced around two probable scenarios’ but has not come to a definitive conclusion on this issue,” he said. CBS News reported.
“Here is their current position: ‘While two elements of IC lean towards the first scenario and one leans more towards the second – each with low or moderate confidence – the majority of elements feel that there is no has not enough information to assess one. be more likely than the other. “”
