Coral reef experiment shows: Acidification from carbon dioxide slows growth
165163 web
(Carnegie Institution for Science) Ocean acidification will severely impair coral reef growth before the end of the century if carbon dioxide emissions continue unchecked. The paper represents the first ocean acidification experiment in which seawater was made artificially acidic by the addition of carbon dioxide and then allowed to flow across a natural coral reef community. The acidity of the seawater was increased to reflect end-of-century projections if carbon dioxide from greenhou... www.eurekalert.org/pub_rele...
Self-driving robots collect water samples to create snapshots of ocean microbes
164822 web
(Monterey Bay Aquarium Research Institute) For the first time, scientists from the University of Hawai'i at Mānoa (UH Mānoa) and the Monterey Bay Aquarium Research Institute (MBARI) will deploy a small fleet of long-range autonomous underwater vehicles (LRAUVs) that have the ability to collect and archive seawater samples automatically. These new robots will allow researchers to track and study ocean microbes in unprecedented detail. www.eurekalert.org/pub_rele...
Ultra-white coating modelled on beetle scales
164973 web
(University of Cambridge) Researchers have developed a super-thin, non-toxic, lightweight, edible ultra-white coating that could be used to make brighter paints and coatings, for use in the cosmetic, food or pharmaceutical industries. www.eurekalert.org/pub_rele...
Plants faring worse than monkeys in increasingly patchy forests of Costa Rica
165184 web
(University of Toronto) A University of Toronto-led study shows that cattle ranching, agriculture and other human activities breaking up Costa Rican forests into isolated patchy fragments, are causing more problems for native plant populations than for monkey species sharing the same habitat. www.eurekalert.org/pub_rele...
Crabs in your computer

(GigaScience) A study published in GigaScience provides three-dimensional visual data from hermit crabs using 3-D microCT scanning technology. The authors not only describe the data, they also provide downloadable, interactive files of everything in this study, allowing everyone to use and manipulate the data. They even include interactive web-based viewers and 3-D printable file formats. Making this complex data publicly available, allows researchers cost-efficient options for examini... www.eurekalert.org/pub_rele...
How the color-changing hogfish 'sees' with its skin
165199 web
(Duke University) The hogfish can go from white to reddish in milliseconds as it adjusts to shifting conditions in the ocean. Scientists have long suspected that animals with quick-changing colors don't just rely on their eyes to tune their appearance to their surroundings -- they also sense light with their skin. But exactly how remains a mystery. A study reveals that hogfish skin senses light differently from eyes. www.eurekalert.org/pub_rele...
Cell-sized mold makes gelatin gels (jelly) 10 times stiffer
165217 web
(Tokyo University of Agriculture and Technology) Micro-sized gels are indispensable for biomedical, cosmetic, and food materials, warranting importance of controlling mechanical properties of a single microgel for application usages. Here it was shown that space sizes for gelation change mechanical properties of gelatin gels. Detailed analysis in the microgel structure revealed that changes in secondary structures of gelatin protein induced the increase of elasticity. These findings sh... www.eurekalert.org/pub_rele...
SOMMa Spanish research institutions to safeguard scientific competitiveness
165482 web
(Center for Genomic Regulation) The creation of SOMMa will allow research centres and units to increase their impact, foster their cooperation and work as a network, and enrich the R+D system as a whole.SOMMa has presented the document 'SOMMa Position Paper: Actions required to safeguarding science competitiveness', which aims at drawing the attention of politicians to tackle some of the current administrative issues urgently and in a long-lasting manner. www.eurekalert.org/pub_rele...

Increasing tree mortality in a warming world

(DOE/Pacific Northwest National Laboratory) A mix of factors is contributing to an increasing mortality rate of trees in the moist tropics, where trees in some areas are dying at about twice the rate that they were 35 years ago. www.eurekalert.org/pub_rele...
