Fraudulent research is 'destroying trust in science'
Fraudulent scientific research
is on the rise and is jeopardizing medical research, experts have warned.
A new study has found that networks of bad actors work together to publish bogus research. The findings, published in the journal
PNAS
this week came from analyzing more than 5 million scientific articles published across 70,000 journals.
"There are groups of editors conspiring to publish low-quality articles, at scale, escaping traditional peer review processes," said the study's lead author Reese Richardson, a social scientist at Northwestern University in the US.
The research uncovered evidence of networks of scientific journal editors who frequently publish research that is flagged for integrity issues, and "brokers" who connect fraudulent authors to these editor networks.

"This kind of fraud destroys
trust in science
. It biases systematic and meta-analysis, it delays treatment and delays new research," said Anna Abalkina, a social scientist at the Free University of Berlin, who was not involved in the study.
Scientific fraud is a growing issue
New scientific research is published as research papers in research journals. There are tens of thousands of different research journals, each publishing different themes of research, and with different levels of scientific impact.
These journals are platforms for researchers to share their findings, theories and ideas with peers and the broader public.
"Historically, the scientific [publication] enterprise has been an engine for progress. It's given us vaccines, antibiotics, the internet, sterile surgery … everything that makes life comfortable for us now," said Richardson.
But sham research is on the rise — as many as one in seven research publications contain fake data, by some estimates. Artificial intelligence is also fueling this research misconduct.
Fraudulent studies contain fabricated data, unverified results, plagiarized research or manipulated images.
"You can map out networks of image duplication that are thousands of articles wide," Richardson said.
Bogus research damages scientific integrity
Fake or poor-quality research is typically caught by journal editors or peer reviewers, but experts warn it is increasingly making its way to publication by groups of bad actors working together.
Several high-profile instances of scientific fraud have been uncovered. During the COVID-19 pandemic, fraudulent research was used to make scientific and political judgments on the merits of hydroxychloroquine as a treatment for COVID infection. Experts linked the issue with "self-promotion journals" — where publication authors are often the editors of the very same journals in which they publish their studies.
Even single fraudulent studies can cause lasting problems. For example, researchers found evidence of image manipulation in a landmark study about Alzheimer's disease. The paper was eventually retracted and the lead scientist resigned, but Abalkina said billions of dollars in research funding and years of research had already been invested from one bad study.
"[It's] incredible what just one paper can do," Abalkina told DW.
How to stamp out corruption in science?
The study's senior author Luis Amaral of Northwestern University said it was "probably the most depressing project I've been involved with."
"It's distressing to see others engage in fraud and in misleading others. But if you believe that science is useful and important for humanity, then you have to fight for it," Amaral said.
Scientific publishing groups are aware of the issue and are working to create new methods to identify and retract fraudulent research. One major publisher, Springer Nature, retracted 2,923 articles from its publications in 2024.
But retracting papers means that bad science has already made it to publication.
Experts like Abalkina and Richardson said the issues ultimately come from how scientific research is valued. Scientific jobs and funding are dependent on scientific publication.
"Where you're faced with a [lack] of resources and yet you're pressured to put out [publications], you're left with two options really: You either buy into scientific fraud, or your leave science. This is a situation that tens of thousands of scientists are in," said Richardson.
That's why the best solution to fight fraudulent publications, he said, is to ditch all quantitative metrics of research assessment like counting publications and citations.

ADHD Medicines Reduce Suicide, Crime Risks In Sweeping Study
Drugs to treat attention deficit hyperactivity disorder were linked to a reduced risk of suicidal behavior, substance misuse and criminality in the first research of its kind. The findings come amid increasing debate around whether ADHD is being over-diagnosed and therefore over-treated with drugs like Ritalin. The research published in the British Medical Journal on Wednesday did not investigate whether patients are being accurately diagnosed, but it does provide evidence supporting medical treatment. ADHD is characterized by difficulties with concentration and impulse control. Roughly 5% of children and 2.5% of adults are estimated to have the condition, which is also associated with an increased risk of substance misuse and self-harm. The researchers wanted to test whether the risk changed with medication. The study design was meant to closely mirror a randomized clinical trial, considered the gold standard of research. The scientists looked at health registry data from almost 150,000 patients newly diagnosed with ADHD in Sweden. At a two-year follow-up, they found that patients taking medicine had a 17% reduction in suicidal behavior and a 15% drop in substance misuse. They also found declines in the risk for criminality and transport accidents. When looking at the recurrence of these behaviors, there were also benefits linked to the medication. While the trial cannot show direct causation and could be confounded by factors such as ADHD severity, it provides doctors with vital evidence showing that drugs can address and reduce important risks, according to one of the authors. "These data should inform clinical guidelines, policies and current debates," said Samuele Cortese, a professor of child and adolescent psychiatry at the University of Southampton. The benefit was greater for patients taking stimulant medications than non-stimulants in the study. Stimulants include drugs like Novartis AG's Ritalin, while non-stimulants include Eli Lilly & Co.'s Strattera. The study results echo other similar conclusions, but "the large sample size, use of a national registry, and more sophisticated analysis give greater confidence in these results that findings aren't explained by something else other than medication use," said Adam Guastella, a clinical psychologist who works at Sydney Children's Hospital at Westmead and the University of Sydney's Brain and Mind Center. He was not involved in the research. Prescriptions in England for ADHD medicines have increased 18% year on year since the Covid-19 pandemic, according to research published in the BMJ Mental Health this year. The surge is believed to be linked to greater awareness of the condition.

Trump signs order to ease commercial spaceflight regulations
. US President Donald Trump signed an executive order on Wednesday that he claimed would ease regulations that govern commercial rocket launches. The order directs the US transportation secretary to eliminate or expedite environmental reviews for launch licenses given by the Federal Aviation Administration (FAA). "Inefficient permitting processes discourage investment and innovation, limiting the ability of US companies to lead in global space markets," the executive order reads. It also calls for the cancellation of "outdated, redundant or overly restrictive rules for launch and reentry vehicles," according to a statement released by the White House. Could the move benefit Elon Musk ? Trump's latest executive order also states that "inefficient" permitting processes "discourage investment and innovation," which in turn limits US companies' ability to lead in global space markets. The move could benefit private space companies such as SpaceX , the company owned by former Trump advisor Elon Musk, despite the two falling out publicly in recent months. The company — which dominates the global private space launches market — plans missions to the Moon and Mars using its Starship rockets, which saw a series of setbackslastly in June as a routine test ended up in an explosion. Environment groups slam executive order Environmental groups have criticized Trump's moves to deregulate commercial spaceflight. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like The boy meets a dog on the street - no one expected what happened next.

The FAA approved an increase in annual SpaceX Starship launches from five to 25 in early may, saying it would not negatively affect the environment. SpaceX boss Musk, the world's richest man, has repeatedly complained that studies over the environmental impact of Starship slow the tests of the rocket, together with post-flight mishap investigations and licensing reviews required by the FAA.
