World: What Is Gain-of-Function Research and Why Is It Controversial?

UMass to bring back Don Brown as next head coach

  UMass to bring back Don Brown as next head coach UMass has made a decision on its next head coach. The Minutemen are trying to rekindle some past success and bringing back Don Brown as their head coach. The hiring was reported on Sunday night and is expected to be announced this week. UMass will be hiring Don Brown as its next head football coach. UMass athletic director Ryan Bamford is expected to conduct a team meeting tomorrow to announce Brown as the next head coach, according to sources inside the program. — Jeff Howe (@jeffphowe) November 22, 2021 Brown turned down a big offer from Arizona in order to return to UMass.

Gain-of-function research rarely garners the attention of the masses, but the pandemic thrust the controversial research into the spotlight and some have used it to point to the Wuhan Institute of Virology as a potential source of the origin of COVID-19.

Picture taken through a multi-glazed security window shows a scientist of the Helmholtz Center for Infection Research (Helmholtz-Zentrum für Infektionsforschung HIZ wearing a special protecitive suit while working in a high security laboratory (security level S3) at the centre in Braunschweig, northern Germany, on May 8, 2020.

Backers of the Wuhan lab as the most likely origin point of the pandemic often cite the lab's clearance to do gain-of-function research because it's in the same city where the first case of COVID-19 was reported. The research involves taking a pathogen and mutating it so that it has a new aspect to it. Often, that new aspect of a virus that it's more transmissible or deadly to humans.

LSU’s top three head-coaching targets reportedly revealed

  LSU’s top three head-coaching targets reportedly revealed Kentucky's Mark Stoops was listed at No. 3 behind Jimbo Fisher and Bill O’Brien. VERY Good LSU source just saw my report and told me the LSU list is this 1. Jimbo Fischer2. Bill O Brien3. Mark Stoops In that order — Matt Jones (@KySportsRadio) November 19, 2021 The list makes sense. Fisher has been a known top target for LSU’s athletic director. O’Brien is the current offensive coordinator at Alabama. He previously was the head coach of the Houston Texans and won the AFC South four times in six seasons. O’Brien also coached Penn State for two seasons before James Franklin took over.

It's a controversial research technique because of the possibility of a lab leak, allowing a mutated pathogen to infect local or global populations. Not all labs are qualified to conduct gain-of-function research and those that are have a certain biosafety level that's intended to put in place layers of safeguards to help prevent leaks, although accidents can occur.

The potential for accidents to occur with a dangerous pathogen raised debate over whether the risks of gain-of-function research outweigh the potential benefits.

In 2014, the Obama administration put a moratorium on funding gain-of-function research after researchers announced they made a deadly bird flu virus, H5N1, more contagious in ferrets. The animals were used as a model for how the virus could spread through humans, sparking concerns about its ability to be released into the world.

That moratorium was lifted in 2017, at which point, the government put a new process in place for researchers who want to conduct and receive funding for gain-of-function research.

Some have blamed gain-of-function research for the COVID-19 pandemic, but Dr. Shi Zhengli, a Chinese virologist who, at times, is referred to as the "Bat Woman" for her research on bat coronaviruses, denied her lab did anything improper.

She told the New York Times in June that she has "nothing to fear" because she is "sure that I did nothing wrong." She rejected assertions that the lab was conducting controversial gain-of-function experiments, but many take the comments with a grain of salt due to China being a closed society, and in May, legislators blocked funding for certain research in China.

Two Republican-led amendments to the Endless Frontier Act that passed the Democrat-majority Senate stops taxpayer money from being used to fund the Wuhan Institute of Virology and gain-of-function research in China.

Fauci hit by Cruz missile in war of words over 'science'

  Fauci hit by Cruz missile in war of words over 'science' Sen. Ted Cruz fired back at Dr. Anthony Fauci in a war of words mixed with a cocktail of science, politics, and COVID-19. © Provided by Washington Examiner The Texas Republican sent a sharply worded tweeted thread in response to Fauci, who is President Joe Biden's chief medical adviser, condemning GOP senators for "dangerous" rhetoric aimed at him, and by extension, science. "Fauci is an unelected technocrat who has distorted science and facts in order to exercise authoritarian control over millions of Americans," Cruz said Sunday evening.

"While many still deny funding gain-of-function research in Wuhan, experts believe otherwise. The passage of my amendment ensures that this never happens in the future. No taxpayer money should have ever been used to fund gain-of-function research in Wuhan, and now we permanently have put it to a stop," Senator Rand Paul, a sponsor of one of the amendments, said in a statement at the time.

Paul has been a vocal advocate for an investigation into the Wuhan lab and expressed concerns about whether gain-of-function research should be being conducted anywhere.

Supporters of the research, including Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, cite it as an important part of preventing future pandemics. By studying how a pathogen could become more dangerous to humans, the next pandemic-potential pathogen could be discovered before a crisis occurs, thereby giving the world time to prepare its response.

"The ability to identify such viruses even a few months faster than by conventional surveillance provides critical time to slow or stop an outbreak," Fauci wrote in a 2011 op-ed for The Washington Post. "Identifying threatening viruses can also facilitate the early stages of manufacturing vaccines that protect against such a virus in advance of an outbreak."
