Zebrafish study to help tackle human aggression
Scientists from the University of Leicester hope to learn how to control human aggression by studying zebrafish.
Scientists from the University of Leicester hope to learn how to control human aggression by studying zebrafish.

Scientists say fish will respond in similar way to drugs as humans

Researchers from the University of Leicester are studying zebrafish as part of an international project to develop treatment for human aggression.

The university's department of biology, will investigate pathological aggression in the fish to understand how genes in the brain function.

They will also use juvenile fish to develop new ways of treating aggression.

Dr Will Norton from the University of Leicester is leading the study.
"We live in an increasingly violent society and we don’t know why.

"Aggression is an extremely complex behaviour which is becoming a big societal problem. There are currently very few drugs available to treat aggression and there are often side-effects for those that exist.

“This is a really ambitious project, but I am hopeful that by looking at the areas of the brain and genes linked to this type of behaviour, we will develop a better understanding of aggression and how it responds to existing treatments.

"We will be using both adult and juvenile zebrafish since they are genetic model organisms which may respond in a similar way to drugs as humans.”

The study forms part of a wider project involving 23 research groups across Europe and the USA.

The five-year EU-funded project will study the biological underpinnings of aggression to develop much-needed treatment strategies.

Dr Norton said: “I’m really excited about the opportunity to collaborate with a wide variety of influential scientists from across the globe as part of this research.

"Not enough is known about aggression and this is an area of interest which definitely needs more focus.

"The end goal for my individual project will be to develop new drugs effective at controlling aggression to increase the treatment options for patients.”

Equine Disease Surveillance report released for Q4 2025

News Story 1
 The latest Equine Disease Surveillance report has been released, with details on equine disease from Q4 of 2025.

The report, produced by Equine Infectious Disease Surveillance, includes advice on rule changes for equine influenza vaccination.

Statistics and maps detail recent outbreaks of equine herpes virus, equine influenza, equine strangles and equine grass sickness. A series of laboratory reports provides data on virology, bacteriology, parasitology and toxicosis.

This issue also features a case study of orthoflavivus-associated neurological disease in a horse in the UK.

NSA webinar explores sheep tailing and castration

The National Sheep Association (NSA) is to host a free webinar on the castration and tail docking of lambs.

The webinar, 'Understanding the tailing and castration consultation: A guide for sheep farmers', will be hosted online on Monday, 2 March 2026 at 7.30pm.

It comes during a government consultation into the methods used for these procedures. Farmers are encouraged to engage before the consultation period closes on Monday, 9 March 2026.

The webinar offers clear and actionable guidance to support farmers to contribute meaningfully to the consultation and prepare for potential changes.

On the panel will be former SVS president Kate Hovers, farmer and vet Ann Van Eetvelt and SRUC professor in Animal Health and Veterinary Sciences Cathy Dwyer. Each panel member will utilise their own specialism and expertise to evaluate risks and outcomes to sheep farming.

Find out more about the webinar on the NSA website.
