Progressive degeneration of photoreceptors—the rods and cones of the eyes—causes blinding diseases such as retinitis pigmentosa and age-related macular degeneration. While there are currently no available treatments to reverse this degeneration, a newly developed compound allows other cells in the eye to act like photoreceptors. As described in a study appearing in the February 19 issue of the Cell Press journal Neuron, the compound may be a potential drug candidate for treating patients suffering from degenerative retinal disorders.

Their effect on the surface of the ocean is negligible, producing a rise of just inches that is virtually imperceptible on a turbulent sea. But internal waves, which are hidden entirely within the ocean, can tower hundreds of feet, with profound effects on the Earth’s climate and on ocean ecosystems.

The formation of the mineral dolomite is still puzzling scientists. Researchers from the Cluster of Excellence "The Future Ocean" and GEOMAR | Helmholtz Centre for Ocean Research Kiel together with colleagues from Switzerland and Spain have now shown that bacteria can facilitate the formation of dolomite. The study has been published online in the international journal "Geology".

In the modern global climate, higher levels of carbon dioxide (CO2) in the atmosphere are associated with rising ocean temperatures. But the seas were not always so sensitive to this CO2 "forcing," according to a new report. Around 5 to 13 million years ago, oceans were warmer than they are today -- even though atmospheric carbon dioxide concentrations were considerably lower.

Based on the study of seven minke whales, scientists at the Woods Hole Oceanographic Institute infer that some baleen whales also have well-formed fat body connecting to the ears which helps in transmitting sound from ocean environment to their inner ears.

Scientists of the Helmholtz Centre for Ocean Research Kiel (GEOMAR) conducted a one year CO2 selection experiment using the calcifying microalgae Emiliania huxleyi and uncovered an enormous potential for adaptation to rapidly changing environments in this important phytoplankton species. After 500 generations under controlled CO2 conditions adapted cultures grew and calcified significantly better compared non-adapted control cultures when tested under ocean acidification conditions. These findings show for the first time that evolutionary adaptation may help to mitigate harmful effects of ocean acidification.
