In a new study, published in Science, researchers from Uppsala University found that larval fish exposed to microplastic particles during development displayed changed behaviors and stunted growth which lead to greatly increased mortality rates. The researchers discovered that larval perch that had access to microplastic particles only ate plastic and ignored their natural food source of free-swimming zooplankton.

The growth of long facial feathers, creating the appearance of muffs and beards on chickens, is caused by a chromosomal rearrangement affecting a gene involved in feather development, report Xiaoxiang Hu of the China Agricultural University in Beijing and colleagues, in a new study published on June 2 in PLOS Genetics.

Sally Fields’s famous Academy Award outburst of gratitude – “You like me, you really like me” – apparently holds true for customers who are asked to participate in retailer-sponsored Web panels, according to an article forthcoming in the June 2016 issue of the Journal of Retailing. One result of these panels, which are growing in popularity, is that participants feel valued by being invited to take part and tend to express their gratitude by buying more and across more different product categories.

Researchers use accelerators to coax the electron into performing a wide range of tricks to enable medical tests and treatments, improve product manufacturing, and power breakthrough scientific research. Now, they’re learning how to coax the same tricks out of the electron’s antimatter twin – the positron – to open up a whole new vista of research and applications.

In the densely populated southeastern U.S., forested watersheds are particularly important to drinking water supplies. Recent estimates show that forests in the Southeast deliver surface drinking water to an estimated 48.7 million people, with streams from the mountainous Southern Appalachian region alone providing water supplies to 10 million people, many of them living in major cities such as Atlanta, Georgia.

Nitrogen dioxide, a pollutant released by cars and fossil fuel burning power plants, can irritate the lungs, contribute to smog formation, and lead to premature deaths in cities around the world. A recent study, conducted at Kings College, London, UK, for example, found that more than 5,000 premature deaths in London annually could be attributed to nitrogen dioxide pollution

A University of York conservationist who put out a call for schools to name a new species of tropical tree has found a winner. Following competitive fundraising totalling nearly £4000, Askham Bryan College, UK pipped the Iringa International School, Tanzania to the post.

In a positive sign for efforts to boost U.S. competitiveness in science and technology, a new study finds that courses that engage college students in conducting scientific research early on can dramatically increase students’ odds of completing a science, technology, engineering or math (STEM) degree.

Using an “intuitive” approach, a SISSA study confirms a recent hypothesis on the formation of galaxies, according to which the larger elliptical galaxies formed in very ancient times through a process of local (in situ) star formation. This contradicts the current paradigm that they formed through the merging of spiral galaxies, a view which, despite being generally accepted by most of the scientific community, has been a source of theoretical inconsistencies.

(Phys.org)—A trio of researchers with Victoria University of Wellington in New Zealand has found that juvenile kaka (forest cousins of the well known kea mountain parrots) are better at solving problems than are older birds in the same area. In their paper published in Proceedings of the Royal Society B, Julia Loepelt, Rachael Shaw and Kevin Burns describe three types of experiments they conducted with wild kaka living in Zealandia Sanctuary, which is located on the North Island’s Wellington peninsula, and what they learned by doing so.
