The PLOS One editors have issued an expression of concern for a 2024 case study concerning the digital economy, innovation factor allocation and industrial structure transformation in China’s Yangtze River Delta city cluster. The notice, published on October 21, 2026, states that the article was identified as one of a series of submissions for which the journal has concerns about the integrity or reliability of the peer-review process. Readers are advised to interpret the original study with this issue in mind.
The notice does not report a new scientific finding, identify an error in the paper or evaluate the study’s scientific validity. According to the editors, PLOS did not assess the article’s integrity or scientific validity when following up on the matter. The expression of concern therefore records a concern about the circumstances surrounding peer review rather than announcing that the study’s data, methods or conclusions have been disproved. The editors also state that they have no concerns regarding the authors’ conduct during the peer-review process.
The affected article was published in PLOS One in 2024 under the title “Digital economy, innovation factor allocation and industrial structure transformation—A case study of the Yangtze River Delta city cluster in China.” The supplied notice does not provide the study’s findings, population details, analytical methods, model estimates, uncertainty measures or specific mechanisms linking the subjects named in the title. As a result, the notice does not support conclusions about the relationship between digital-economy development, innovation factors and industrial structure in the region, nor does it establish whether any reported association or causal effect is reliable.
For the wider research record, the immediate effect is that the 2024 article is accompanied by an editorial notice questioning the integrity or reliability of its peer-review process. The notice does not provide details about the submissions or explain the specific basis for the journal’s concerns. It also does not announce a correction, replacement analysis or revised conclusion. The central status of the paper’s scientific validity remains unevaluated in the supplied material, while the issue is sufficiently significant for PLOS One to advise readers to consider it when interpreting the study.

A curious recent discovery has revealed a promising new underground archaeological find at the ancient site of Buto in Egypt’s Nile Delta.
Researchers who were testing a remote sensing technology designed to locate buried structures and other below-ground features reported the unique find earlier this year, which could be a previously undiscovered tomb or temple now believed to date as far back as 2,600 years.
The discovery was made at the Tell el-Fara’in site, more commonly known as Buto, which comprises the remains of an ancient city that thrived around 5,600 years ago during Egypt’s Predynastic period.
Origins of a Mystery
Buto underwent several periods of destruction and reassembly throughout its history, making it a significant focus of past archaeological work.
Some of the city’s oldest portions are currently entombed beneath several centuries’ worth of accumulated mud and soil, a factor that significantly complicates traditional excavations. To help them locate an ideal location for future excavation, the team employed an approach that combined SAR (Sentinel-1 GRD) satellite imagery with electrical resistivity tomography (ERT) measurements, which helped them pinpoint an ideal location to dig that would best enable an investigation of Buto’s settlement phases.
“Sentinel-1 (C-band) satellite imagery captured on May 5, 2018, was processed using SNAP software (version 9.0.0) to identify large-scale anomalies indicative of buried structures,” the team reports in a paper detailing their findings, which appeared in Applied Geophysics in March.
“Based on these detected anomalies, the locations for ERT profiles were strategically selected to maximize the likelihood of indicating significant subsurface features,” the team explained.
ERT technology is ideal for such carefully targeted excavation, since it relies on electrical currents placed into the ground, which researchers then use to collect data that helps them assemble a three-dimensional model of the buried structures. This imagery is generated based on differences in the way various materials either display electrical conductivity or resistance.
Buried Discoveries Emerge
Based on the team’s scans, the top three meters of the area revealed a distinctive layer of material, which the team judged to be broken pottery and debris—likely associated with Roman periods of occupation.
However, going further down in their scans, descending to a depth of approximately six meters, the team discovered something more intriguing: what appeared to be some kind of large buried structure.
Based on its depth, the team believes this unique structure is likely associated with the Saite period, which dates it to around 2,600 years ago. Although it remains unknown precisely what the structure is, or what its exact purpose may have been, one possibility is that it could be a large shrine, or even a tomb.
Uncovering Religious Artifacts
Following the initial discovery, the team undertook preliminary excavations of a small 10 x 10-meter area. This revealed walls constructed of mudbrick, as well as religious artifacts in locations that aligned with the team’s scans.
“The presence of a small offering basin along with numerous religious amulets depicting Egyptian deities such as Isis, Horus, Taweret, and Wadjet further supports the temple hypothesis,” the team writes in their study.

Also among the religious artifacts uncovered at the site were a “remarkable bronze amulet with a suspension hole, representing Horus the child” as well as amulets featuring a crouching lion, an amulet of Anubis, and the remains of limestone statues “in sexual positions” along with “a faience plaque with relief carvings of Hathor on both sides.”
However, the team reports that one of the most significant artifacts recovered from this area of the excavation was a steatite scarab bearing the name of King Thutmose III, which the team believes “may have functioned as an amulet or seal.”
“Collectively, these artefacts indicate the presence of a religious site with strong cultic and ceremonial associations, further reinforcing the interpretation of the structure as a temple from the 26th Dynasty,” the team says.
Ongoing Excavations
While still in the early phases, the team’s discoveries so far help to validate the geophysical and remote sensing techniques that made the discovery possible. “The results of this study demonstrate the effectiveness of combining geophysical measurements and remote sensing data,” the team writes, adding that they provided “a very accurate vision in detecting buried settlements in a complex region.”
“3D inversion algorithms were particularly effective in delineating buried mudbrick walls and architectural structures, significantly enhancing our understanding of site formation processes,” the researchers add.
Going forward, the team recommends further ERT surveys, which may help to reveal additional information about the site’s deepest occupation levels. For the time being, the team believes the evidence in hand points to the interpretation of the site and its features as an ancient temple, and that evidence points to the possibility that another may be located nearby.
“Our findings suggest that, in addition to the known temple, another temple may remain buried under a thick clay layer, which will be investigated through extensive measurements in forthcoming studies,” the team writes.
The recent paper, “Multi-scale detection of buried archaeological elements across different occupation phases: an integrated approach using radar satellite imagery and electric resistivity tomography at Buto, northwestern Nile Delta of Egypt,” appeared in Applied Geophysics on March 10, 2026.
