Researchers in England devised a new method for monitoring biodiversity with an insect soup and low cost DNA sequencing, according to a University of East Anglia press release.
Douglas Yu, a biology professor and the lead researcher for the study, said analyzing a few hundred ground-up bugs gives researchers equivalent data to traditional intensive methods for a fraction of the cost.
He said, compared to high quality data sets analyzing 55,000 arthropods and birds, sequencing bug juice was just as effective.
The researchers use a process called metabarcoding to identify bugs and biodiversity of an environment.
The measurement could eventually be established as a low cost, low impact way to understand the biodiversity of a system through some of its smallest creatures.Read More
Researchers from a Swiss university found plastic particulate is widespread in Lake Geneva, according to a press release from the École Polytechnique Fédérale de Lausanne.
The researchers sampled the lake in several ways to quantify microplastic pollution. Every sample taken for the study, whether from bird droppings, fish dissection, beach combing or a net drag had plastic particles in it.
No quantity of just how much plastic is in the lake was given in the release. Further studies will evaluate plastic content of lakes and rivers across Switzerland.Read More
In the battle against harmful algal blooms (HABs), time is important . The need for laboratory equipment and testing is a serious challenge for water managers. This issue caught the eye of Qingshan Wei , an assistant professor of chemical and biomolecular engineering at North Carolina State University .
“Our research group is interested in developing low-cost sensors,” Wei told EM . “Recently we have been developing sensors for environmental monitoring, and cyanotoxins came to our attention .”
Cyanobacteria, which generate HABs, are becoming a challenge across the US . They are a very serious problem in North Carolina, in part due to the weather.Read More
