They feel like lightning — sudden, brilliant and seemingly impossible to predict. But according to new research, those mind-flashing “aha” moments of insight may leave detectable traces before they strike.
Scientists have developed a way to identify subtle behavioral changes that happen minutes before a breakthrough, offering a new window into the elusive mechanics of human creativity.
The study was published in the Proceedings of the National Academy of Sciences. Shadab Tabatabaeian, who earned her Ph.D. in Cognitive and Information Sciences from the University of California, Merced, is lead author, and Tyler Marghetis, UC Merced assistant professor of Cognitive and Information Sciences, is senior author. Co-authors are Artemisia O’bi (Indiana University) and David Landy (Netflix and Indiana University).
Their work builds on theories from statistical physics and ecology to answer an old question with a modern twist: Can we spot the approach of a eureka moment in real time?
The team video-recorded six Ph.D.-level mathematicians as they wrestled with notoriously tough problems from the William Lowell Putnam Mathematical Competition. Filming took place in the mathematicians’ offices and in seminar rooms, chalk in hand. The researchers documented more than 4,600 moment-to-moment interactions with blackboard “inscriptions” — writing, pointing, erasing and shifting attention.
They found a striking pattern. In the minutes before a mathematician suddenly exclaimed “aha!” or “I see it!” their behavior became measurably less predictable. Familiar patterns of moving between ideas gave way to novel, unprecedented connections.
Using a measure from information theory, the researchers quantified this unpredictability and found it reliably ramped up before verbalized insights.
“This is one of those discoveries that was possible only because we made connections between very different scientific disciplines,” Marghetis said. “We took ideas from ecology and physics, added tools from information theory, and combined them with a century of work on the psychology of creativity.
“The resulting discovery belongs to all of those disciplines but also to none of them. It's its own thing.”
Though the experiment focused on expert mathematics, the researchers said the method could work in any field where thinking unfolds in observable steps, such as a chemist sketching molecular bonds, a designer shifting between prototypes, or an artist exploring new forms. The authors suggest their approach could help scientists better understand the micro-dynamics of creativity and, perhaps, even predict breakthroughs before they happen.

An alphabet for hand actions in the human brain
2025-08-18
Using a corkscrew, writing a letter with a pen or unlocking a door by turning a key are actions that seem simple but actually require a complex orchestration of precise movements. So, how does the brain do it?
According to a new study by researchers from Carnegie Mellon University and the University of Coimbra, the human brain has a specialized system that builds these actions in a surprisingly systematic way.
Analogous to how all of the words in a language can be created by recombining the letters of its alphabet, the full repertoire ...
When rattlesnakes marry their cousins
2025-08-18
Roads, buildings and farms are preventing Michigan’s only rattlesnake from finding mates outside of their population. A 15-year study shows that fragmentation into smaller, more isolated patches is likely reducing the threatened snake’s chances of survival.
Michigan State University conservation biologists traced the family histories of more than 1,000 Eastern Massasauga rattlesnakes caught and released in a U.S. Fish and Wildlife Service-funded project. The new findings, published in the Proceedings of the National Academy of Sciences, surprised even the researchers – the most inbred snakes were ...
Mass spectrometry sequencing of circulating antibodies from a malaria-exposed child provides new insight into malaria immunity
2025-08-18
Malaria, caused by Plasmodium falciparum, remains a major global health threat, claiming 600,000 lives annually, mostly young children in sub-Saharan Africa. Immunity to severe malaria develops after repeated infections and is mediated by antibodies blocking the parasite’s highly diversified PfEMP1 adhesion proteins from binding to the human endothelial protein C receptor (EPCR) on blood vessel walls.
In the collaborative study, researchers from the National Institute for Medical Research in Tanzania and the University of Copenhagen first identified donors with immune plasma able to ...
SwRI-led work confirms decades-old theoretical models about solar reconnection
2025-08-18
SAN ANTONIO — August 18, 2025 — New research led by Southwest Research Institute (SwRI) has confirmed decades-old theoretical models about magnetic reconnection, the process that releases stored magnetic energy to drive solar flares, coronal mass ejections and other space weather phenomena. The data was captured by NASA’s Parker Solar Probe (PSP), which is the only spacecraft to have flown through the Sun’s upper atmosphere.
Magnetic reconnection occurs when magnetic field lines in plasma sever and reconnect in a new configuration, releasing large amounts of stored energy. ...
New Study identifies early signs of valve failure one year after TAVI, raising durability concerns in younger patients
2025-08-18
A new study published in The Annals of Thoracic Surgery, a journal from The Society of Thoracic Surgeons, has identified early hemodynamic valve deterioration (HVD) in more than 6% of patients just one year after undergoing transcatheter aortic valve implantation (TAVI), raising new questions about valve durability in younger, lower-risk populations.
The retrospective study, which analyzed 10 years of procedures from 2012 to 2022, evaluated 2,123 patients who had complete echocardiographic follow-up data. Researchers found that patients with 1-year HVD were more likely to be younger and have smaller aortic annuli than those without HVD. Importantly, ...
Untangling glucose traffic jams in Type 2 diabetes
2025-08-18
Just as smart traffic management ensures smooth vehicular movement during peak hours, our body relies on a molecular traffic system to manage the surge in glucose levels after a meal. Pancreatic β-cells play a major role in this system by taking up glucose from the blood and triggering insulin release into the bloodstream. Inside these cells, glucose uptake is managed by glucose transporters (GLUTs) – proteins that move to the β-cell surface when blood glucose levels rise and facilitate the entry of glucose into the cell ...
University of Houston professor creates new drug delivery system to tackle lupus
2025-08-18
With a $1 million Impact Award from the U.S. Department of Defense, Tianfu Wu, a University of Houston biomedical engineer, is developing a method to send medication directly to the spleen where certain immune cells cause the disease known as lupus, or Systemic Lupus Erythematosus.
Lupus is a debilitating autoimmune disease characterized by uncontrolled disease activity, frequent flares, long-term immunosuppression, increasing infection rates, cumulative organ damage and decreased quality of life.
The spleen has often been called the security guard of the bloodstream, filtering out old or damaged blood cells while housing millions of white blood cells, or lymphocytes, that carry ...
Community-based approach boosts family engagement in ADHD care
2025-08-18
Innovative intervention delivered by trained community health workers – meaning nonclinical personnel with deep knowledge of the community – increased treatment utilization among participating families with children who have ADHD, according to a pilot study published in the Journal of Attention Disorders. This intervention for parents and caregivers, covering topics that range from education about ADHD to discussions of stigma and barriers to care, intends to reduce inequities in access to evidence-based treatment and boost family engagement in ADHD care.
“We know from previous studies that compared to White youth, Black, Hispanic, and Asian ...
Identifying a compass in the human brain
2025-08-18
Zhengang Lu and Russell Epstein, from the University of Pennsylvania, led a study to explore how people maintain their sense of direction while navigating naturalistic, virtual reality cities.
As reported in their new JNeurosci paper, the researchers collected neuroimaging data while 15 participants performed a taxi driving task in a virtual reality city. Two brain regions represented forward-facing direction as people moved around. This neural signal was consistent across variations of the city with different visual features. The signal was also ...
How AI support can go wrong in safety-critical settings
2025-08-18
COLUMBUS, Ohio – When it comes to adopting artificial intelligence in high-stakes settings like hospitals and airplanes, good AI performance and a brief worker training on the technology is not sufficient to ensure systems will run smoothly and patients and passengers will be safe, a new study suggests.
Instead, algorithms and the people who use them in the most safety-critical organizations must be evaluated simultaneously to get an accurate view of AI’s effects on human decision making, researchers say.
The team also contends these evaluations should assess how people respond to good, mediocre and poor technology performance ...
