The genetic explanation for moles’ poor eyesight

21.10.2008
Due to their underground habitats, moles' eyes have been modified by natural selection in ways very different from those of surface-dwelling animals.

New research, published in the open access journal BMC Biology, features a detailed anatomical and genetic examination of the changes that result from living life in the dark.

A team of researchers led by J Martin Collinson from the University of Aberdeen has carried out the first molecular study of the entire process of lens development in a subterranean animal - the Iberian mole, Talpa occidentalis, which has permanently closed eyes unlike the closely related European mole found in gardens throughout Britain.

According to Collinson "Our results show that there are primary developmental defects in the lens of this insectivore. As a result, the adult lens is composed of a disrupted epithelium and a disorganised mass of immature and nucleated fibre cells."

The genetic information the authors amassed shows that the internal defects in the animals' eyes are not the result of an adult degenerative condition but because development of the eye lens fibres, which starts normally, is not completed. The expression of some genes that are central to eye development is also abnormal.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Interference as a new method for cooling quantum devices

Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
