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 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.”

Practices urged to audit neutering data

News Story 1
 RCVS Knowledge has called on vet practices to audit their post-operative neutering outcomes.

It follows the release of the 2024 NASAN benchmarking report, which collates data from neutering procedures performed on dogs, cats and rabbits.

The benchmarking report enables practices in the UK and Ireland to compare their post-operative outcomes to the national average. This includes the rate of patients lost to follow-up, which in 2024 increased to 23 per cent.

Anyone from the practice can submit the data using a free template. The deadline for next report is February 2026.

Visit the RCVS Knowledge website to complete an audit.

UK's BSE risk status downgraded

The WOAH has downgraded the UK's international risk status for BSE to 'negligible'.

Defra says that the UK's improved risk status recognises the reputation for having the highest standards for biosecurity. It adds that it demonstrates decades of rigorous animal control.

Outbreaks of Bovine Spongiform Encephalopathy, also known as mad cow disease, have previously resulted in bans on Britain's beef exports.

The UK's new status could lead to expanded trade and better confidence in British beef.

Christine Middlemiss, the UK's chief veterinary officer, said: "WOAH's recognition of the UK as negligible risk for BSE is a significant milestone and is a testament to the UK's strong biosecurity measures and the hard work and vigilance of farmers and livestock keepers across the country who have all played their part in managing the spread of this disease.
