Horses ‘mane’ inspiration for new generation of social robots

2025-05-28
(Press-News.org) Interactive robots should not just be passive companions, but active partners–like therapy horses who respond to human emotion–say University of Bristol researchers.

Equine-assisted interventions (EAIs) offer a powerful alternative to traditional talking therapies for patients with PTSD, trauma and autism, who struggle to express and regulate emotions through words alone.

The study, presented at the CHI '25: Proceedings of the 2025 CHI Conference on Human Factors in Computing Systems held in Yokohama, recommends that therapeutic robots should also exhibit a level of autonomy, rather than one-dimensional displays of friendship and compliance.

Lead author Ellen Weir from Bristol’s Faculty of Science and Engineering explains: “Most social robots today are designed to be obedient and predictable - following commands and prioritising user comfort.

“Our research challenges this assumption.”

In EAIs, individuals communicate with horses through body language and emotional energy. If someone is tense or unregulated, the horse resists their cues. When the individual becomes calm, clear, and confident, the horse responds positively. This ‘living mirror’ effect helps participants recognise and adjust their emotional states, improving both internal well-being and social interactions.

However, EAIs require highly trained horses and facilitators, making them expensive and inaccessible.

Ellen continued: “We found that therapeutic robots should not be passive companions but active co-workers, like EAI horses.

“Just as horses respond only when a person is calm and emotionally regulated, therapeutic robots should resist engagement when users are stressed or unsettled. By requiring emotional regulation before responding, these robots could mirror the therapeutic effect of EAIs, rather than simply providing comfort.”

This approach has the potential to transform robotic therapy, helping users develop self-awareness and regulation skills, just as horses do in EAIs.

Beyond therapy, this concept could influence human-robot interaction in other fields, such as training robots for social skills development, emotional coaching, or even stress management in workplaces.

A key question is whether robots can truly replicate - or at least complement - the emotional depth of human-animal interactions. Future research must explore how robotic behaviour can foster trust, empathy, and fine tuning, ensuring these machines support emotional well-being in a meaningful way.

Ellen added: “The next challenge is designing robots that can interpret human emotions and respond dynamically—just as horses do. This requires advances in emotional sensing, movement dynamics, and machine learning.

“We must also consider the ethical implications of replacing sentient animals with machines. Could a robot ever offer the same therapeutic value as a living horse? And if so, how do we ensure these interactions remain ethical, effective, and emotionally authentic?”

Too much of a good thing: Consequences of overplanting Bt corn in the US

2025-05-28
May 28, 2025 MSU has a satellite uplink/LTN TV studio and Comrex line for radio interviews upon request. Why this matters: Too much of a specific type of Bt corn — genetically modified to produce insecticides against corn rootworm — is being planted in places that don’t have a high risk of corn rootworms destroying corn crops. This overuse is causing corn rootworms to become resistant, or immune, to Bt insecticides. So Bt corn isn’t working as well now in Corn Belt states where corn rootworm is a serious risk, as rootworms are becoming increasingly pesticide resistant. Corn rootworm is one of the worst ...

Kinetic coupling – breakthrough in understanding biochemical networks

2025-05-28
A new concept of kinetic modules in biochemical networks could revolutionize the understanding of how these networks function. Scientists from the University of Potsdam and the Max Planck Institute of Molecular Plant Physiology in Golm succeeded in linking the structure and dynamics of biochemical networks via kinetic modules, thus clarifying a systems biology question that has been open for longtime. Their groundbreaking findings were published today in the journal “Science Advances”. Biochemical networks are the central processing units of a cell that enable it to process signals and convert molecules into building blocks ...

Rice researchers lay groundwork for designer hybrid 2D materials

2025-05-28
HOUSTON – (May 28, 2025) – Some of the most promising materials for future technologies come in layers just one atom thick ⎯ graphene, e.g., a sheet of carbon atoms arranged in a hexagonal lattice, prized for its exceptional strength and conductivity. While hundreds of such materials exist, truly merging them into something new has remained a challenge. Most efforts simply stack these atom-thin sheets like a deck of cards, but the layers typically lack significant interaction between them. An international team of researchers led by Rice University ...

Lack of gender lens in tobacco control research could stymie efforts to help smokers quit, York University researchers say

2025-05-28
TORONTO, May 28, 2025 – Ahead of World No Tobacco Day on May 31, York University researchers with Global Strategy Lab (GSL) have published a paper that finds a lack of gender analysis in tobacco control research. The researchers say this means that we could be missing out on important strategies accounting for gendered behaviors that could help smokers quit. The paper, published today in BMJ Tobacco Control, is the first in a series of papers coming out of York University and GSL on gender and smoking.  “In the tobacco ...

Diagnosing Parkinson’s using a blood-based genetic signature

2025-05-28
Parkinson’s disease is best known for its effects on the central nervous system. In addition, recent scientific advances generally emphasize the role of the immune system in the presence and development of the disease. In a study published today in Brain, researchers led by Université de Montréal associate professor of neuroscience Martine Tétreault show that some cell types in the immune system are activated more in patients who have Parkinson’s. “Thanks to a new technology called single-cell RNA-seq, we can differentiate ...

IBD on the rise: International research highlights spread in Africa, Asia, and Latin America

2025-05-28
Inflammatory bowel disease, which includes Crohn’s disease and ulcerative colitis, has long been considered a modern condition of the industrialized West, with cases steadily increasing in North America and Europe throughout the 20th century. New research conducted by an international consortium shows that IBD and related conditions are now spreading through developing regions in Africa, Asia, and Latin America as well. The study, published in Nature, used data from more than 500 population-based studies covering more than 80 geographic regions to describe a pattern of four distinct stages IBD ...

After mild stroke, more sleep or time spent trying to sleep tied to thinking problems

2025-05-28
MINNEAPOLIS — After a mild stroke or transient ischemic attack (TIA), people who spend more time in bed sleeping or trying to sleep may be more likely to have lower scores on tests of thinking and memory skills and changes in their brains that can lead to dementia or second strokes, according to a study published on May 28, 2025, online in Neurology®, the medical journal of the American Academy of Neurology. Spending longer in bed—when some of that time can be not sleeping due to difficulty falling asleep, fragmented sleep, poor quality sleep or other problems—can be a sign of a sleep disorder. The study found that both people ...

Huge sea-urchin populations are overwhelming Hawaii’s coral reefs

2025-05-28
As coral reefs struggle to adapt to warming waters, high levels of pollution and sea-level rise, ballooning sea-urchin populations are threatening to push some reefs in Hawaii past the point of recovery. The phenomenon is described in a new study that uses on-site field work and airborne imagery to track the health of the reef in Hōnaunau Bay, Hawaii. Overfishing is the main culprit behind the explosion in sea-urchin numbers, said Kelly van Woesik, Ph.D. student in the North Carolina State University Center for Geospatial Analytics and first author of the study. “Fishing in these areas has greatly reduced the number of fishes that feed on these ...
