Chicken study sheds light on childhood eye disease
Scientists at the Roslin Institute studied chicken embryos to determine how fusion occurs.

New genes identified that are linked to ocular coloboma

A study of chicken embryos has identified new genes that could be responsible for the development of ocular coloboma in humans.

Ocular coloboma causes part of the eye to be missing at birth, severely affecting the patient’s vision. It accounts for up to 10 per cent of all childhood blindness and cannot be treated.

The disease is the result of errors in tissue fusion, which is essential for the formation of the eye and many other organs of the developing embryo.

Scientists at the Roslin Institute studied chicken embryos to determine how fusion occurs and identified genes that are switched on or off during the process.

One of the many newly identified genes included Netrin-1, which scientists say is likely to be critical in humans and other species, as well as in organs other than the eye.

Lead author Dr Joe Rainger said: “Identifying new genes and processes involved in tissue fusion will improve our understanding of how fusion defects occur, and whether these may be preventable.

"The fusion-genes we have revealed are also an excellent resource to support the identification of genetic defects in patient sequencing programmes.”

Rare chimp birth announced at Edinburgh Zoo

News Story 1
 The Royal Zoological Society of Scotland (RZSS) welcomed the birth of a critically endangered western chimpanzee on Monday 3 February at Edinburgh Zoo's Budongo Trail.

The baby girl will be named in the coming days through a public vote, and staff will carry out a paternity test during its first health check to determine the father.

Mother Heleen's first infant, Velu, was born in 2014, making this new baby only the second chimpanzee born in Scotland for more than 20 years.

Budongo Trail team leader Donald Gow said: "While we celebrate every birth, this one is particularly special because our new arrival is a critically endangered Western chimpanzee, a rare subspecies of chimpanzee."

BEVA offering free membership to vet students

The British Equine Veterinary Association (BEVA) is offering free membership to veterinary students. As part of a new initiative with the aim of encouraging more veterinary professionals into equine practice.

According to BEVA, less than one in ten veterinary students choose to work in equine practice. The association hopes that this initiative will provide insight into the field and the benefits of a career in equine medicine.

Benefits of membership include:
▪ access to a network of nearly 3,000 members
▪ special student rates to attend BEVA Congress
▪ online access to BEVA's Equine Veterinary Education (EVE) journal
▪ free access to the association's online learning platform
▪ free access to BEVA's practical veterinary apps
▪ exclusive discounts on a range of things from cinema tickets to grocery shopping.

BEVA will be releasing a series of short videos over the next few months from BEVA Council members, explaining what inspired them to work in equine practice.
