Tall el-Hammam was a Bronze-Age city in current Jordan that is a site of archaeological interest. It is believed by some to be the biblical city of Sodom. According to the Bible, Sodom and Gomorrah were cities full of sinners, which were destroyed by “sulfur and fire” sent by God.
A paper published last week in Scientific Reports now claims that Tall el-Hammam was destroyed by a “cosmic airburst”, perhaps by the impact of a meteorite or comet. The article provides evidence of melted pottery and plaster, shocked quartz, and diamond-like carbon, all suggesting the city was exposed to a sudden high-temperature event.
The paper got a lot of media attention. However, several images presented in the paper appear to contain repetitive elements, suggestive of cloning.
This morning a professor at a US university warned me that they had gotten an email from a person pretending to be me. The email came from email@example.com, and was signed with my name. But that is not my email address!
The email sent to the professor flagged a scientific paper as “The following article is fake. The impact on society is very bad”.
Maybe I should feel flattered, but it is quite disturbing that people pretend to be me.
So here is a quick warning that there are Elisabeth Bik impersonators using fake email addresses. My correct email address is eliesbik at gmail dot com and if an email comes from any other address that is not me!
Update January 2022:
Several other fake email addresses have been reported over the last months. I will list all of them here and update if needed. None of them is me!
After an anonymous tip about some papers by the Şen Research Group with possible duplicated graphs, I started digging around a bit more. And I found a couple more papers with duplications. And more. Quite a lot more. As of now, the SRG has 84 papers flagged on PubPeer. [Excel spreadsheet; PDF version]
How does one scan for duplicated images in scientific paper, and how can one determine if those are a sign of misconduct? This post will give some background about my past and current work on this topic.
This blog post expresses my personal opinion and is not an accusation of misconduct.
An exciting new paper about STAT3
The STAT (“signal transducer and activator of transcription“) protein family consists of proteins involved in many important aspects of cellular function, such as growth, differentiation, and apoptosis (programmed cell death). These transcription activators are activated themselves if other molecules bind to them, and they act as messengers that transfer changes outside of a cell to inside the nucleus, by binding to promoters and determining which genes are switched on or off. One of STAT proteins, STAT3, in particular has been the topic of many studies, because it might play a role in cancer. Simply put, the continuous activation of STAT3 might induce cancer, and STAT3 might be a target for new anti-cancer drugs.
A recent study, published on 28 August 2019 in Nature by authors from Harvard Medical School and the Dana Farber Cancer Institute, therefore gained quite some attention. It reported on one of the ways by which STAT3 can be activated, through the binding of fatty acids in a process called palmitoylation.
One of my recent investigations led me to expand my set of figure types to look at. For our 2016 mBio study, in which I scanned >20,000 papers for image duplication, I focused on real photos of Western blots, agarose gels, tissue sections, etc.
One of the best-known examples of data falsification is a study described in a 1998 Lancet paper with Dr. Andrew Wakefield as the lead author. In this paper, 12 children with autism and chronic enterocolitis were described, and these symptoms started immediately after MMR (Measles / Mumps / Rubella) vaccination in 8 of these children.
However, a 2004 investigation by Sunday Times reporter Brian Deer revealed concerning issues with patient recruitment and undisclosed financial conflicts of interest.
