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.

RCVS annual renewal fee for vets due

RCVS' annual renewal fee for veterinary surgeons is now due. Vets must pay their renewal fee before Wednesday, 1 April 2026.

This year's standard annual fee has increased to 431 from last year's 418. This is an approximately three per cent increase, as approved by RCVS Council and the Privy Council.

Tshidi Gardner, RCVS treasurer, said: "The small fee increase will be used to help deliver both our everyday activities and our new ambitious Strategic Plan, which includes aims such as achieving new legislation, reviewing the Codes of Professional Conduct and supporting guidance, and continuing to support the professions through activities such as the Mind Matters Initiative, RCVS Academy and career development."

A full breakdown of the new fees is on the RCVS website. Information about tax relief is available on the UK government website.
