Previously unknown 'biological oddity' found in animal species
Results could offer tool to study human aging

For the first time in any animal species, a type of "selfish" mitochondrial DNA that is actually compromising the organism's chance of survival has been discovered.

Researchers at the Oregon State University have made the discovery and published their findings in the journal PLoS One. A biological oddity previously unknown in animals, the DNA bears a strong similarity to some damage done to human cells as they age, and it is thought that these new findings may provide an important new tool to study human aging.

The discovery was made almost by accident during genetic research being carried out on a nematode, Caenorhabditis briggsae, a type of roundworm.

Dee Denver, an OSU associate professor of biology, said: "We weren't even looking for this when we found it, at first we thought it must be a laboratory error. Selfish DNA is not supposed to be found in animals. But it could turn out to be fairly important as a new genetic model to study the type of mitochondria decay that is associated with human aging."

Such selfish mitochondrial DNA has been found before in plants, but not animals.

FIVP launches CMA remedies survey

News Story 1
 FIVP has shared a survey, inviting those working in independent practice to share their views on the CMA's proposed remedies.

The Impact Assessment will help inform the group's response to the CMA, as it prepares to submit further evidence to the Inquiry Group. FIVP will also be attending a hearing in November.

Data will be anonymised and used solely for FIVP's response to the CMA. The survey will close on Friday, 31 October 2025.

Free webinar explores congenital heart disease in dogs

A free webinar is to provide veterinary professionals, dog breeders and pet owners an new insights into congenital heart disease.

Chris Linney, a cardiology specialist and Veterinary Cardiovascular Society (VSC) member, will present the webinar from 7.00pm to 8.30pm on Wednesday, 12 November.

Dr Linney will explore the types, causes and clinical presentation of congenital heart conditions. This will include diagnostic approaches, treatment pathways and emerging research opportunities.

The session is the third to be organised by The Kennel Club, with the VCS, following an introductory webinar and a talk on acquired heart disease. Dr Linney's webinar consists of a one-hour presentation, followed by a 30-minute question and answer session.

Dr Linney said: "This webinar will be an opportunity to deepen understanding - not just of the diseases themselves, but of how breeders, vets and owners can work together to support affected dogs and improve outcomes for future generations."
