(Press-News.org) Five minutes of training can significantly improve people's ability to identify fake faces created by artificial intelligence, new research shows.
Scientists from the University of Reading, Greenwich, Leeds and Lincoln tested 664 participants' ability to distinguish between real human faces and faces generated by computer software called StyleGAN3. Without any training, super-recognisers (individuals who score significantly higher than average on face recognition tests) correctly identified fake faces 41% of the time, while participants with typical abilities scored just 31%. If they had their eyes closed and guessed, people would perform at around 50% (chance level).
A new set of participants who received a brief training procedure, which highlighted common computer rendering mistakes such as unusual hair patterns or incorrect numbers of teeth, had higher accuracy. Super-recognisers achieved 64% accuracy in detecting fake faces, while typical participants scored 51% accuracy.
Dr Katie Gray, lead researcher at the University of Reading, said: "Computer-generated faces pose genuine security risks. They have been used to create fake social media profiles, bypass identity verification systems and create false documents. The faces produced by the latest generation of artificial intelligence software are extremely realistic. People often judge AI-generated faces as more realistic than actual human faces.
“Our training procedure is brief and easy to implement. The results suggest that combining this training with the natural abilities of super-recognisers could help tackle real-world problems, such as verifying identities online."
Advancing software poses a tough challenge
The training affected both groups equally, suggesting super-recognisers may use different visual cues than typical observers when identifying synthetic faces, rather than simply being better at spotting rendering errors.
The research, published today (Wednesday, 12 November) in Royal Society Open Science, tested faces created by StyleGAN3, the most advanced system available when the study was conducted. This represents a significant challenge compared to earlier research using older software, as participants in this study tended to have poorer performance than those in previous studies. Future research will examine whether the training effects last over time and how super-recognisers' skills might complement artificial intelligence detection tools.

Shouting at seagulls could stop them stealing your food
2025-11-12
Shouting at seagulls makes them more likely to leave your food alone, research shows.
University of Exeter researchers put a closed Tupperware box of chips on the ground to pique herring gulls’ interest.
Once a gull approached, they played either a recording of a male voice shouting the words, “No, stay away, that’s my food”, the same voice speaking those words, or the ‘neutral’ birdsong of a robin.
They tested a total of 61 gulls across nine seaside towns in Cornwall and found that ...
AI detects hidden objects on chest scans better than radiologists
2025-11-12
UNDER EMBARGO UNTIL 00:01 UK TIME ON WEDNESDAY 12 NOVEMBER 2025
Researchers at the University of Southampton have developed an artificial intelligence (AI) tool that can spot hard-to-see objects lodged in patients’ airways better than expert radiologists.
In a study published in npj Digital Medicine, the AI model outperformed radiologists in checking CT scans for objects that don’t show up well on scans.
These accidentally inhaled objects can cause coughing, choking, difficulty breathing and sometimes lead to more serious complications if not treated properly.
The findings highlight how AI can support doctors in diagnosing complex and potentially life-threatening conditions.

Breakthrough gives hope in fight against aggressive form of blood cancer
2025-11-12
Researchers at the University of Southampton have identified a new subtype of lymphoma which could pave the way to improved and more targeted treatments for some blood cancer patients.
The cancer scientists and biologists have also found that lymphoma cells of this new subtype carry a unique sugar that promotes the survival and growth of the cancer.
Lymphoma is a type of blood cancer that affects white blood cells called lymphocytes. There are many different types of lymphoma, but this latest breakthrough is in a type called diffuse large B-cell lymphoma (DLBCL), which affects our B cells. When operating ...
Experts find £90K “sweet spot” for crowdfunding success
2025-11-12
A new study led by the University of East Anglia (UEA) reveals what drives investors to put their money behind business start-ups.
Researchers analysed more than a thousand successful crowdfunding campaigns on the platform Seedrs.
They found that setting a £90K “sweet spot” target, having around 19 team members, and using certain phrases including “health” and “organic” in campaign pitches all helped attract investors.
Offering a high equity percentage in return for investment was also found to be crucial – with low equity ratios putting investors off.
The researchers hope their work could help entrepreneurs fine-tune ...
Tough little wallaby sets the scene for kangaroo bounding success
2025-11-12
Flinders University fossil experts have unearthed more clues about why kangaroos and wallabies have endured to become one of the continent’s most prolific marsupial groups.
They have analysed the powerful limbs of Australia’s earliest ‘true’ kangaroo – the shared ancestor of modern-day kangaroos and wallabies.
The palaeontologists focused on the limb bones of the extinct Dorcopsoides fossilis, found only in the rich Alcoota fossil field in the southern Northern Territory.
Lead investigator Dr Isaac Kerr says these hardy hopping marsupials, which lived around 7 million years ago in a period called the Late Miocene, are ...
Scientists develop low-cost sensor to safeguard water from fireworks pollution
2025-11-11
A team of researchers from Nanjing University and Nanjing Normal University has designed a new, affordable sensor to detect toxic perchlorate in water, paving the way for better environmental monitoring and healthier communities. The sensor, inspired by porphyrin molecules and costing less than two US dollars, offers rapid and highly accurate detection of perchlorate, a harmful pollutant that often escapes into rivers and drinking water through fireworks manufacturing and industrial operations.
Perchlorate is a persistent pollutant known for its mobility, water solubility, and stability. While perchlorate can occur naturally, ...
Researchers aim to disrupt breast cancer line of communication and prevent spread
2025-11-11
Cancer Center at Illinois (CCIL) Program Leader Erik Nelson’s lab made an important discovery about the relationship between cholesterol and breast cancer progression with crucial implications for breast cancer therapeutics.
Breast cancer is the second leading cause of cancer-related death for American women, and more than 90% of breast cancer deaths are caused by metastatic spread of the disease. While breast cancer therapies have improved significantly in recent years, scientists do not yet understand the totality of molecular mechanisms involved in breast cancer progression and treatment ...
A sit-stand ratio ‘sweet spot’ may boost office productivity
2025-11-11
New research has found a simple sit-stand routine at work significantly reduces lower back pain, offering a high-impact solution for employees in sedentary work environments.
While the Griffith University-led study focused on individuals with recent lower back pain, the recommended ratio of 30 minutes sitting followed by 15 minutes standing (30:15) could benefit all desk-based workers by improving focus, reducing stress, and encouraging regular movement patterns throughout the day.
In collaboration with co-authors ...
New computational process could help condense decades of disease biology research into days
2025-11-11
At 10 one-millionths of a meter wide, a single human cell is tiny. But something even smaller exerts an enormous influence on everything a cell does: proton concentration, or pH. On the microscopic level, pH-dependent structures regulate cell movement and division. Altered pH response can accelerate the development of cancers and neurodegenerative diseases such as Alzheimer’s and Huntington’s.
Researchers hope that pinpointing pH-sensitive structures in proteins would help them determine how proteins respond to pH changes in normal and diseased cells alike and, ultimately, to ...
