Vision is essential for the survival of most animal species and tears provide potentially life-saving protection for the eyes. A new first-of-its-kind study looks at the composition of bird and reptile tears and compares these findings to human tears. These results provide clues about tear evolution, as well as potential starting points for better eye treatments.
It took two years and $11 million, but eventually ranchers, politicians and scientists came to a consensus about how to prevent flooding in Tillamook, a coastal Oregon town. A recent study by Portland State University researchers examined the social factors involved in this decision-making process. This study showcases how environmental justice can be served when affected parties have a seat at the table.
An Iowa State University scientists contributed to a global effort to assemble the genome of the tuatara, a rare reptile species native to New Zealand. The tuatara genome sheds light on the genomic structure of a huge range of species, including humans.
From 2007 to 2009, a devastating yellow fever virus outbreak nearly decimated brown and black and gold howler monkey populations at El Parque El Piñalito in northeastern Argentina. An international research team tested if howlers who survived the outbreak had any genetic variations that may have kept them alive. In brown howlers, they found two mutations on immune genes that resulted in amino acid changes in the part of the protein that detects the disease.
New research using the most comprehensive study of feathered dinosaurs and early birds has revised the evolutionary relationships of dinosaurs at the origin of birds. An international team of researchers, including McGill University Professor Hans Larsson published their findings in the journal Current Biology. The team pored over fossils, developed a novel analytical pipeline to search for evolutionary trees, and estimated how each species may have crossed the stringent thresholds for powered flight.
In flood-prone areas of the Hudson River valley in New York state, census areas with more white and affluent home owners tend to file a higher percentage of flood insurance claims than lower-income, minority residents, according to a new study.
Tropical Depression 06W has been around for days, and continues to hold together as it moves in a westerly direction toward Taiwan in the Northwestern Pacific Ocean. NASA-NOAA's Suomi NPP satellite captured a visible image of the storm.
Applications range from sensors and batteries to fuel cells, among other technological possibilities. Achieving a deeper understanding and control of the processes involved is the goal of the Campinas Electrochemistry Group.
NASA's Aqua satellite obtained visible imagery of Hurricane Elida in the Eastern Pacific as it continued to weaken. Imagery revealed that Elida's eye had become covered as the storm embarks on a weakening trend over cooler waters.
Synthetic polymers have changed the world around us. However, It is hard to finely tune some of their properties, such as the ability to transport ions. To overcome this problem, assistant professor Giuseppe Portale decided to take inspiration from nature and created a new class of polymers based on protein-like materials that work as proton conductors and might be useful in future bio-electronic devices.
