Allegations of research fakery at a leading cancer center have turned a spotlight on scientific integrity and the amateur sleuths uncovering image manipulation in published research.
Dana-Farber Cancer Institute, a Harvard Medical School affiliate, announced Jan. 22 it's requesting retractions and corrections of scientific papers after a British blogger flagged problems in early January.
The blogger, 32-year-old Sholto David, of Pontypridd, Wales, is a scientist-sleuth who detects cut-and-paste image manipulation in published scientific papers.
He's not the only hobbyist poking through pixels. Other champions of scientific integrity are keeping researchers and science journals on their toes. They use special software, oversize computer monitors and their eagle eyes to find flipped, duplicated and stretched images, along with potential plagiarism, The Associated Press reported.
A look at the situation at Dana-Farber and the sleuths hunting sloppy errors and outright fabrications:
WHAT HAPPENED AT DANA-FARBER?
In a Jan. 2 blog post, Sholto David presented suspicious images from more than 30 published papers by four Dana-Farber scientists, including CEO Laurie Glimcher and COO William Hahn.
Many images appeared to have duplicated segments that would make the scientists' results look stronger. The papers under scrutiny involve lab research on the workings of cells. One involved samples from bone marrow from human volunteers.
The blog post included problems spotted by David and others previously exposed by sleuths on PubPeer, a site that allows anonymous comments on scientific papers.
Student journalists at The Harvard Crimson covered the story on Jan. 12, followed by reports in other news media. Sharpening the attention was the recent plagiarism investigation involving former Harvard president Claudine Gay, who resigned early this year.
HOW DID DANA-FARBER RESPOND?
Dana-Farber said it already had been looking into some of the problems before the blog post. By Jan. 22, the institution said it was in the process of requesting six retractions of published research and that another 31 papers warranted corrections.
Retractions are serious. When a journal retracts an article that usually means the research is so severely flawed that the findings are no longer reliable.
Dr. Barrett Rollins, research integrity officer at Dana-Farber, said in a statement: “Following the usual practice at Dana-Farber to review any potential data error and make corrections when warranted, the institution and its scientists already have taken prompt and decisive action in 97 percent of the cases that had been flagged by blogger Sholto David."
WHO ARE THE SLEUTHS?
California microbiologist Elisabeth Bik, 57, has been sleuthing for a decade. Based on her work, scientific journals have retracted 1,133 articles, corrected 1,017 others and printed 153 expressions of concern, according to a spreadsheet where she tracks what happens after she reports problems.
She has found doctored images of bacteria, cell cultures and western blots, a lab technique for detecting proteins.
“Science should be about finding the truth,” Bik told The Associated Press. She published an analysis in the American Society for Microbiology in 2016: Of more than 20,000 peer-reviewed papers, nearly 4% had image problems, about half where the manipulation seemed intentional.
Bik's work brings donations from Patreon subscribers of about $2,300 per month and occasional honoraria from speaking engagements. David told AP his Patreon income recently picked up to $216 per month.
Technology has made it easier to root out image manipulation and plagiarism, said New York University science educator Ivan Oransky, co-founder of the Retraction Watch blog. The sleuths download scientific papers and use software tools to help find problems.
Others doing the investigative work remain anonymous and post their findings under pseudonyms. Together, they have “changed the equation” in scientific publication, Oransky said.
“They want science to be and do better,” Oransky said. “And they are frustrated by how uninterested most people in academia — and certainly in publishing — are in correcting the record.” They're also concerned about the erosion of public trust in science. WHAT MOTIVATES MISCONDUCT?
Bik said some mistakes could be sloppy errors where images were mislabeled or “somebody just grabbed the wrong photo.”
But some images are obviously altered with sections duplicated or rotated or flipped. Scientists building their careers or seeking tenure face pressure to get published. Some may intentionally falsify data, knowing that the process of peer review — when a journal sends a manuscript to experts for comments — is unlikely to catch fakery.
“At the end of the day, the motivation is to get published,” Oransky said. “When the images don’t match the story you’re trying to tell, you beautify them.”
WHAT HAPPENS NEXT?
Scientific journals investigate errors brought to their attention but usually keep their processes confidential until they take action with a retraction or correction.
Some journals told the AP they are aware of the concerns raised by David's blog post and were looking into the matter.

In China, humanoid robots are serving as Lunar New Year entertainment, with their manufacturers pitching their song-and-dance skills to the general public as well as potential customers, investors and government officials.

On Sunday, Shanghai-based robotics start-up Agibot live-streamed an almost hour-long variety show featuring its robots dancing, performing acrobatics and magic, lip-syncing ballads and performing in comedy sketches. Other Agibot humanoid robots waved from an audience section.

An estimated 1.4 million people watched on the Chinese streaming platform Douyin. Agibot, which called the promotional stunt "the world's first robot-powered gala," did not have an immediate estimate for total viewership.

The ‌show ran a ‌week ahead of China's annual Spring Festival gala ‌to ⁠be aired ‌by state television, an event that has become an important - if unlikely - venue for Chinese robot makers to show off their success.

A squad of 16 full-size humanoids from Unitree joined human dancers in performing at China Central Television's 2025 gala, drawing stunned accolades from millions of viewers.

Less than three weeks later, Unitree's founder was invited to a high-profile symposium chaired by Chinese President Xi Jinping. The Hangzhou-based robotics ⁠firm has since been preparing for a potential initial public offering.

This year's CCTV gala will include ‌participation by four humanoid robot startups, Unitree, Galbot, Noetix ‍and MagicLab, the companies and broadcaster ‍have said.

Agibot's gala employed over 200 robots. It was streamed on social ‍media platforms RedNote, Sina Weibo, TikTok and its Chinese version Douyin. Chinese-language television networks HTTV and iCiTi TV also broadcast the performance.

"When robots begin to understand Lunar New Year and begin to have a sense of humor, the human-computer interaction may come faster than we think," Ma Hongyun, a photographer and writer with 4.8 million followers on Weibo, said in a post.

Agibot, which says ⁠its humanoid robots are designed for a range of applications, including in education, entertainment and factories, plans to launch an initial public offering in Hong Kong, Reuters has reported.

State-run Securities Times said Agibot had opted out of the CCTV gala in order to focus spending on research and development. The company did not respond to a request for comment.

The company demonstrated two of its robots to Xi during a visit in April last year.

US billionaire Elon Musk, who has pivoted automaker Tesla toward a focus on artificial intelligence and the Optimus humanoid robot, has said the only competitive threat he faces in robotics is from Chinese firms.

AI to Track Icebergs Adrift at Sea in Boon for Science

British scientists said Thursday that a world-first AI tool to catalogue and track icebergs as they break apart into smaller chunks could fill a "major blind spot" in predicting climate change.

Icebergs release enormous volumes of freshwater when they melt on the open water, affecting global climate patterns and altering ocean currents and ecosystems, reported AFP.

But scientists have long struggled to keep track of these floating behemoths once they break into thousands of smaller chunks, their fate and impact on the climate largely lost to the seas.

To fill in the gap, the British Antarctic Survey has developed an AI system that automatically identifies and names individual icebergs at birth and tracks their sometimes decades-long journey to a watery grave.

Using satellite images, the tool captures the distinct shape of icebergs as they break off -- or calve -- from glaciers and ice sheets on land.

As they disintegrate over time, the machine performs a giant puzzle problem, linking the smaller "child" fragments back to the "parent" and creating detailed family trees never before possible at this scale.

It represents a huge improvement on existing methods, where scientists pore over satellite images to visually identify and track only the largest icebergs one by one.

The AI system, which was tested using satellite observations over Greenland, provides "vital new information" for scientists and improves predictions about the future climate, said the British Antarctic Survey.

Knowing where these giant slabs of freshwater were melting into the ocean was especially crucial with ice loss expected to increase in a warming world, it added.

"What's exciting is that this finally gives us the observations we've been missing," Ben Evans, a machine learning expert at the British Antarctic Survey, said in a statement.

"We've gone from tracking a few famous icebergs to building full family trees. For the first time, we can see where each fragment came from, where it goes and why that matters for the climate."

This use of AI could also be adapted to aid safe passage for navigators through treacherous polar regions littered by icebergs.

Iceberg calving is a natural process. But scientists say the rate at which they were being lost from Antarctica is increasing, probably because of human-induced climate change.

AMD Predicts Weaker First-Quarter Sales, Shares Plunge on Nvidia Comparisons

Advanced Micro Devices on Tuesday forecast a slight decline in quarterly revenue, raising concerns about whether it ​can effectively challenge Nvidia in the booming AI market and sending its shares tumbling 8% in after-hours trade.

The lackluster prediction comes despite an unexpected boost from sales of certain artificial intelligence chips to China, which began in the last quarter after the Trump administration approved a license for orders that AMD received in early 2025.

And without those sales to China which generated $390 million, AMD's data-center segment would have missed estimates for the fourth quarter.

AMD said it expects revenue of about $9.8 billion this quarter, plus or minus $300 million. That's down from $10.27 billion in the fourth-quarter which was up 34% year-on-year and ahead of LSEG ‌estimates for $9.67 billion.

PALES ‌NEXT TO NVIDIA

Though AMD is seen as one of the ‌few ⁠contenders ​that can seriously ‌challenge Nvidia, investors noted the stark contrast between the two companies' performances. AMD expects an adjusted gross margin of 55% this quarter. Nvidia has said it expects adjusted gross margin in the mid-70% range during its fiscal 2027.

"The expectations for large blowout quarters for AI-related hardware companies have skewed what the market is looking for," said Bob O'Donnell, president of TECHnalysis Research.

The forecast for the current first quarter includes $100 million from sales to China, where the situation remains "dynamic," AMD CEO Lisa Su said on a conference call with investors.

The US government ⁠has placed restrictions on the exports of advanced chips to China, but AMD received licenses to sell modified versions of its MI300 series ‌of AI chips there. Its MI308 chip competes with Nvidia's H20 ‍chip in China.

OPENAI SALES

AMD has accelerated its ‍product launches and is moving into selling full AI systems to better compete against Nvidia, which now ‍provides "rack-scale" systems that combine GPUs, CPUs and networking gear.

Last year, it entered into a multi-year deal to supply AI chips to ChatGPT-owner OpenAI, which would bring in tens of billions of dollars in annual revenue and give the startup the option to buy up to roughly 10% of the chipmaker.

Su reiterated on Tuesday that the company ​expects sales of a new flagship AI server to OpenAI and others to rise rapidly in the second half of this year, saying a global memory-chip crunch will not ⁠slow its plans.

"I do not believe that we will be supply-limited in terms of the ramp that we put in place," Su said.

BEYOND OPENAI

As Big Tech and governments across the globe double down on investing in AI hardware, shares in Santa Clara, California-based AMD have doubled since the start of 2025, outperforming a 60% bump in the broader chip index.

But analysts remain concerned that AMD's success remains tied to a handful of customers that rivals such as Nvidia could try to poach. Reuters reported this week that Nvidia made a $20 billion move to hire most of chip startup Groq's founders after OpenAI held chip supply discussions with the startup.

"Growth appears concentrated in large deployments and specific regions, and China shipments are significant enough to influence a quarter," said eMarketer analyst Gadjo Sevilla.

Revenue in AMD's key data-center segment grew 39% to $5.38 billion in the ‌fourth quarter. But excluding sales of the MI308, which is a data-center chip, that revenue would have been $4.99 billion, below estimates of $5.07 billion.
