We learn physical skills by feeling rewarded, even in the absence of a reward, finds new study
People master new physical skills, such as sports, crafts or controlling a vehicle while driving, by blending lessons learnt from both feedback on the amount of error they had in failures and the rewards of successes, even when reward cues are removed, according to a new study led by Dr Shlomi Haar from the University of Surrey.
Using a high-tech virtual reality pool setup, researchers from Surrey and Imperial College London had 32 participants play pool on a physical table while wearing a virtual reality (VR) headset that slightly changed the cue ball’s trajectory, forcing players to adapt.
In the study, published in npj science of learning, two different sessions took place, with different feedback given to each player taking part. In one session, players only got “error feedback”, with the balls disappearing before they could pocket them. In the other session, participants only got “reward feedback”, with successful shots being artificially shown pocketing, while failed shots gave no visual results. The goal was to see whether the brain would only use the type of feedback it was given.
However, the brain behaved differently. Even when the reward – pocketing the ball – was taken away in the “error feedback” condition, players still showed strong signs of using reward-based learning. They were seen to be finding their own “mini rewards”, such as observing the ball taking a correct-looking path. The brain wouldn’t ignore that key information, much like seasoned basketball players can anticipate a good shot before it goes through the hoop.
Measurements of brain activity confirmed this complex interaction, showing a mixed learning pattern, rather than separate processes as seen in past lab experiments. While players were seen to learn faster when focusing on errors, the underlying process in both conditions was always a blend of the two processes.
Dr Shlomi Haar, lead author and Senior Lecturer in Cognitive Neuroscience at the University of Surrey, said:
"The brain is a highly active detective, always seeking every available piece of information - whether it's seeing the mistake or anticipating success. Our findings suggest that the most effective learning embraces and strategically uses both error information and rewards together, and visual feedback interventions could be used to enhance it further.”

Scientists on ‘urgent’ quest to explain consciousness as AI gathers pace
2025-10-30
As AI—and the ethical debate surrounding it—accelerates, scientists argue that understanding consciousness is now more urgent than ever.
Researchers writing in Frontiers in Science warn that advances in AI and neurotechnology are outpacing our understanding of consciousness—with potentially serious ethical consequences.
They argue that explaining how consciousness arises—which could one day lead to scientific tests to detect it—is now an urgent scientific and ethical priority. Such an understanding would bring major implications for AI, prenatal policy, animal welfare, medicine, mental health, law, and emerging neurotechnologies such as brain–computer ...
Drones reveal unexpectedly high emissions from wastewater treatment plants
2025-10-30
Greenhouse gas emissions from many wastewater treatment plants may be more than twice as large as previously thought. This is shown in a new study from Linköping University, where the researchers used drones with specially manufactured sensors to measure methane and nitrous oxide emissions.
“We show that certain greenhouse gas emissions from wastewater treatment plants have been unknown. Now that we know more about these emissions, we also know more about how they can be reduced,” says ...
Dancing alleviated perceived symptoms of depression and helped to understand its root causes
2025-10-30
Dance as a performative art form alleviates perceived symptoms of depression, helps to understand its root causes and promotes self-actualisation, a recent study from the University of Eastern Finland found. The multidisciplinary research collaboration brought together perspectives from psychology and social psychology, as well as from dance as a performative art form, which is rarely included in interventions related to depression.
“Depression is a major public health concern, and there is an urgent need for adjunct treatment methods. Robust evidence regarding adjunct treatments for depression already exists for physical exercise, for example. ...
Tricky treats: Why pumpkins accumulate pollutants
2025-10-30
Pumpkins, squash, zucchini and their relatives accumulate soil pollutants in their edible parts. A Kobe University team has now identified the cause, making it possible to both make the produce safer and create plants that clean contaminated soil.
The gourd family of plants comprising pumpkins, zucchini, melons, cucumbers and more are known to accumulate high levels of pollutants in their edible parts. Kobe University agricultural scientist INUI Hideyuki says: “The pollutants don’t easily break down and thus pose a health risk to people who eat the fruit. Interestingly, other plants don’t ...
Revealing the molecular structures of sugars using galectin-10 protein crystals
2025-10-30
A quick, purification-free method was developed by researchers at Institute of Science Tokyo, to capture the detailed 3D structures of flexible sugar molecules. By growing crystals of galectin-10 protein using a cell-free crystallization process and soaking them in sugar solution, the researchers were able to trap and analyze the molecular arrangement of sugars and their interactions with the protein. This offers a powerful tool to accelerate research in drug discovery and molecular biology.
Sugars, or saccharides, do much more than sweeten food. In living organisms, these molecules decorate the surfaces of cell and also act as vital messengers in processes such as infection control and tissue ...

GLP-1 drugs effective for weight loss, but more independent studies needed
2025-10-30
Three new Cochrane reviews find evidence that GLP-1 drugs result in clinically meaningful weight loss, but industry-funded studies raise questions. The reviews were commissioned by the World Health Organization (WHO) to inform upcoming guidelines on the use of these drugs to treat obesity.
The reviews, which examine the effects of three weight loss drugs known as GLP-1 receptor antagonists, have found that all three drugs result in clinically meaningful weight loss compared with placebo. However, evidence on longer-term ...
Researchers uncover previously unexplored details of mosquito’s specialized detection mechanisms
2025-10-30
It’s bound to happen at a summer picnic, a peaceful walk in the woods or simply sitting in your backyard… a mosquito targets your blood for its next meal. You’ve been bitten.
But how do mosquitoes find you?
Among several methods used to locate new hosts for blood sucking, mosquitoes feature a keen ability to detect carbon dioxide. As we breathe out, we emit CO2 into the air around us, which mosquitoes can sense. But how?
Scientists have been aware of the mosquito’s ability to detect our carbon dioxide expirations but the intricate underlying physiological structures enabling these capabilities largely have remained ...
Stem cell therapy linked to lower risk of heart failure after a heart attack
2025-10-30
Patients with weak heart function who receive stem cell therapy shortly after a heart attack are at lower risk of developing heart failure and related hospital stays compared with standard care, finds a clinical trial published by The BMJ today.
The researchers say the findings suggest this technique may be a valuable add-on procedure for this particular group of patients after a heart attack to prevent subsequent heart failure and reduce the risk of future adverse events.
Advances in heart attack ...
The NHS is reaching a crisis point in consultant recruitment, new report warns
2025-10-30
The NHS is reaching a crisis point in consultant recruitment as 1 in 3 consultant posts lie vacant in some parts of the UK and recruiting managers regularly wait over 12 months to secure a candidate, leading to increased locum costs, finds a new report published by BMJ Careers today.
Data obtained under the Freedom of Information Act reveal that these shortages are costing the health service upwards of £674m on locum consultants and are negatively affecting staff morale and patient care. Relying on expensive agency staff also risks derailing work to cut waiting lists.
One resident doctor at a north London trust said: “It’s a complete nightmare ...
