Scientists in the Conway Institute of Biomolecular & Biomedical Research have restored the sight of blind zebrafish whose eyes failed to develop due to a genetic mutation. The findings, published this week in Developmental Biology, are exciting first steps on a long road to understanding eye diseases in humans.
Dr. Breandan Kennedy and his colleagues at the University of Washington, Seattle and the Hubrecht Laboratory in Utrecht, Netherlands first identified a family of eyeless fish. They then discovered the gene that controls initial development of eye tissue (retinal homeobox 3 or rx3) and that mutations in this gene resulted in the eyeless fish.
When Dr. Kennedy and his research team introduced a normal copy of the rx3 gene into fish embryos that had inherited the mutated version of the gene, they discovered that this treatment restored normal eye development. Recent studies from researchers in the Unites States have shown that mutations in the human form of this gene cause anophthalmia, a disease in which eyes also fail to form.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
