Is it time to assume that health research is fraudulent until proven otherwise?

Is it time to assume that health research is fraudulent until proven otherwise?

Richard Smith, former editor of the British Medical Journal, writes: Health research is based on trust. Health professionals and journal editors reading the results of a clinical trial assume that the trial happened and that the results were honestly reported. But about 20% of the time, said Ben Mol, professor of obstetrics and gynaecology at Monash Health, they would be wrong. As I’ve been concerned about research fraud for 40 years, I wasn’t that surprised as many would be by…

Huge study supporting ivermectin as Covid treatment withdrawn. Data appears ‘totally faked’

Huge study supporting ivermectin as Covid treatment withdrawn. Data appears ‘totally faked’

The Guardian reports: The efficacy of a drug being promoted by rightwing figures worldwide for treating Covid-19 is in serious doubt after a major study suggesting the treatment is effective against the virus was withdrawn due to “ethical concerns”. The preprint study on the efficacy and safety of ivermectin – a drug used against parasites such as worms and headlice – in treating Covid-19, led by Dr Ahmed Elgazzar from Benha University in Egypt, was published on the Research Square…

Will Covid-19 change science? Past pandemics offer clues

Will Covid-19 change science? Past pandemics offer clues

Science reports: Although the past may not presage the future, epidemic history illuminates how change unfolds. “Historians often say that what an epidemic will do is expose underlying fault lines,” says Erica Charters, a historian of medicine at the University of Oxford who is studying how epidemics end. But how we respond is up to us. “When we ask, ‘How does the epidemic change society?’ it suggests there’s something in the disease that will guide us. But the disease doesn’t…

The story of songbirds is a story of sugar

The story of songbirds is a story of sugar

Ed Yong writes: Australia’s unique forests are the birthplace of birdsong. The plants there are drenched in sunlight and can readily mass-produce sugars through photosynthesis. But with few nutrients in the soil, they struggle to convert those sugars into leaves, seeds, and other tissues. They end up with excess, which they simply give away. Flowers overflow with nectar. Eucalyptus trees exude a sweet substance called manna from their bark. Even insects that suck plant sap are forced to excrete surplus…

Covid origins mirror SARS’s genesis in animals, study finds

Covid origins mirror SARS’s genesis in animals, study finds

Bloomberg reports: Early Covid-19 cases traced to markets in Wuhan, China, mirror the initial spread of SARS 17 years earlier, scientists said in a paper that concludes that an animal contagion is the most likely explanation for the pandemic’s genesis. The epidemiological history of SARS-CoV-2 is comparable to previous animal market-associated outbreaks of coronaviruses and offers a simple route for human exposure, Edward Holmes, Andrew Rambaut and 19 other researchers said Wednesday in a review of the scientific evidence pertaining…

Birthday parties as virus vector

Birthday parties as virus vector

Margot Sanger-Katz writes: At the height of the pandemic, it was easy to worry that strangers would give you the virus. But a new study of what happened after people’s birthdays suggests that people we trust were also a common source of viral spread. Private gatherings have been harder for researchers to measure than big public events — they’re private, after all. And there has been a fierce debate for months among epidemiologists about just how big a factor they…

Inside the risky bat-virus engineering that links America to Wuhan

Inside the risky bat-virus engineering that links America to Wuhan

Rowan Jacobsen writes: In 2013, the American virologist Ralph Baric approached Zhengli Shi at a meeting. Baric was a top expert in coronaviruses, with hundreds of papers to his credit, and Shi, along with her team at the Wuhan Institute of Virology, had been discovering them by the fistful in bat caves. In one sample of bat guano, Shi had detected the genome of a new virus, called SHC014, that was one of the two closest relatives to the original…

A lack of coronavirus genomes could prolong the pandemic

A lack of coronavirus genomes could prolong the pandemic

Puja Changoiwala writes: Back at the beginning of the COVID-19 pandemic, before the disease had even drawn the attention of much of the world, researchers in China and Australia mapped the genome of the coronavirus isolated from one of the first patients in the Wuhan outbreak. This first genetic blueprint of the SARS-CoV-2 virus was publicly released soon after, on January 10, 2020. The disclosure of that genome, and others that soon followed, guided the vigorous international scientific response to…

Virologist Danielle Anderson paints a very different picture of the Wuhan Institute

Virologist Danielle Anderson paints a very different picture of the Wuhan Institute

Bloomberg reports: From her first visit before it formally opened in 2018, Anderson was impressed with the institute’s maximum biocontainment lab. The concrete, bunker-style building has the highest biosafety designation, and requires air, water and waste to be filtered and sterilized before it leaves the facility. There were strict protocols and requirements aimed at containing the pathogens being studied, Anderson said, and researchers underwent 45 hours of training to be certified to work independently in the lab. The induction process…

Where did the coronavirus come from? What we already know is troubling

Where did the coronavirus come from? What we already know is troubling

Zeynep Tufekci writes: There were curious characteristics about the H1N1 influenza pandemic of 1977-78, which emerged from northeastern Asia and killed an estimated 700,000 people around the world. For one, it almost exclusively affected people in their mid-20s or younger. Scientists discovered another oddity that could explain the first: It was virtually identical to a strain that circulated in the 1950s. People born before that had immunity that protected them, and younger people didn’t. But how on earth had it…

When a good scientist is the wrong source

When a good scientist is the wrong source

Thomas Levenson writes: Six weeks ago, a reporter, Nicholas Wade, published what seemed to be a blockbuster story, one that, if true, would expose the greatest scandal in recent history. SARS-CoV-2, he wrote, or SARS2 for short, the virus that has driven the global COVID-19 pandemic, had likely been modified in a lab at the Wuhan Institute of Virology, from which it then escaped into the wild. “Neither the natural emergence nor the lab escape hypothesis can yet be ruled…

Lab leaks happen, and not just in China. We need to take them seriously

Lab leaks happen, and not just in China. We need to take them seriously

David A. Relman writes: If we scientists are not forced to confront the issues of laboratory safety and risky research in a serious and sustained manner, history suggests that we will not do so. In 2012, controversy erupted when it transpired that two sets of researchers — at the University of Wisconsin at Madison and Erasmus Medical Center in Rotterdam, the Netherlands — were altering highly pathogenic avian influenza viruses to enhance their transmissibility among mammals (to understand their potential…

Chinese Covid-19 genetic data that could have aided pandemic research removed from NIH database

Chinese Covid-19 genetic data that could have aided pandemic research removed from NIH database

The Wall Street Journal reports: Chinese researchers directed the U.S. National Institutes of Health to delete gene sequences of early Covid-19 cases from a key scientific database, raising concerns that scientists studying the origin of the pandemic may lack access to key pieces of information. The NIH confirmed that it deleted the sequences after receiving a request from a Chinese researcher who had submitted them three months earlier. “Submitting investigators hold the rights to their data and can request withdrawal…

New $3.2 billion program will support the development of drug to treat Covid-19

New $3.2 billion program will support the development of drug to treat Covid-19

The New York Times reports: The U.S. government spent more than $18 billion last year funding drugmakers to make a Covid vaccine, an effort that led to at least five highly effective shots in record time. Now it’s pouring more than $3 billion on a neglected area of research: developing pills to fight the virus early in the course of infection, potentially saving many lives in the years to come. The new program, announced on Thursday by the Department of…

What Covid-19’s long tail is revealing about chronic disease

What Covid-19’s long tail is revealing about chronic disease

David Cox writes: One of the major challenges for doctors attempting to treat long Covid is that there are likely to be a variety of underlying triggers or causes, depending on the patient. Recent epidemics have provided one way of gaining crucial clues about what these underlying causes might be. Far from being unique to Sars-CoV-2 – the virus that causes Covid-19 – some scientists believe almost all infectious outbreaks leave behind a proportion of patients who remain chronically unwell…

The FDA should be our toughest regulatory body, but the pharmaceutical lobby has torn it to shreds

Natalie Shure writes: Last week the Food and Drug Administration approved Aduhelm—the first new Alzheimer’s drug in 18 years—an event that, at first blush, heralds the amazing news of a medical advance. Perhaps it might have been, had the whole process leading up to the agency giving its nod to the medication played out in a functional health care system. But that’s not what happened. Far from hailing the advent of a transformative breakthrough for the six million Americans suffering…
