A deadly amphibian disease called severe Perkinsea infections, or SPI, is the cause of many large-scale frog die-offs in the United States, according to a new study by the US Geological Survey.
NOAA Fisheries researchers and colleagues at the New England Aquarium have developed a new model to improve estimates of abundance and population trends of endangered North Atlantic right whales, which have declined in numbers and productivity in recent years. Between 1990 and 2010 abundance increased to 482 animals, but since 2010 the numbers have declined to 458 in 2015, with 14 known deaths this year. The findings were published in the journal Ecology and Evolution.
A new method for analyzing a living being chemical compositions is tested in Andean plants and attest the genesis of species by means of geographic isolation. Scientific article published August 2017 by Brazilian researchers is based on the analysis of chemical compounds which express specific biogeographic trends at the evolutionary process, validating a Smithsonian hypothesis on the evolution of the genus Espeletia in the process.
Sushi is sublime. Just fresh fish and seasoned rice in its simplest form served one on top of the other, or rolled up with some veggies in a seaweed wrapper. But creates the subtle interplay of flavors in your tuna nigiri? Take a deep dive into the chemistry of rice, fish and seaweed in this video from Reactions: https://youtu.be/6F_OWtoTTrA
ETH researchers have discovered a new method to design stable foams. Their findings could make beer froth and ice cream last longer -- and revolutionise construction materials such as concrete.
Researchers from the Department of Food Science (FOOD) at the University of Copenhagen in Denmark are the first in the world to have analysed whole grains with long near-infrared wavelengths using a new type of light source, the supercontinuum laser. The research has significance for our knowledge of food ingredients and may, for example, eventually lead to better quality of bread and beer.
New England has been losing forestland to development at a rate of 65 acres per day, according to a new report released today by the Harvard Forest, a research institute of Harvard University, and a team of authors from across the region. Public funding for land protection has also been steadily declining in all six New England states and is now half what it was at its 2008 peak; with land conservation trends following suit.
To provide a vital scientific foundation for conservation efforts, an international team has conducted a genetic analysis comparing queen conch at 19 sites throughout the Caribbean. Their findings, published Sept. 19 in the journal Diversity and Distributions, will help scientists understand how local subpopulations of conch are fragmented throughout the Caribbean, an essential first step needed to develop effective science-driven management plans and practices.
A single species gave rise to 220 more and two distinct lineages of oaks -- red oaks and white oaks -- that moved through the boreal zone to populate large swaths of the continent all the way into Mexico. These two findings -- simultaneous evolutionary diversification in the red and white oaks, each following the same geographic routes; and two relatively recent origins of the Mexican oaks -- are a surprise conclusion to a scientific mystery.
In the US, therapeutic horseback riding offers equine-assisted therapy to diverse populations who have anxiety disorders. Veterans diagnosed with post-traumatic stress disorder often are prescribed this type of therapy to cope with anxiety, but little is known about how these programs affect the stress levels in horses. Now, a University of Missouri study has revealed that horses ridden by veterans with PTSD did not have undue physiological stress responses while participating in a therapy program.
