(Chalmers University of Technology) Water which has been contaminated with mercury and other toxic heavy metals is a major cause of environmental damage and health problems worldwide. Now, researchers from Chalmers University of Technology, Sweden, present a totally new way to clean contaminated water, through an electrochemical process. The results are published in the scientific journal Nature Communications.

(Princeton University) Princeton biologist Bridgett vonHoldt is best known for her work with canines, but when she compared the genes of large-beaked Cameroonian finches to those of their smaller-beaked counterparts, she found the answer to a 20-year old mystery: 300,000 base pairs, apparently inherited as a unit, always varied between them, and right in the middle of that genetic sequence was the well-known growth factor, IGF-1.

(Pensoft Publishers) Chinese scientists report the first cave-dwelling centipede so far known from southern China. Collected last year during a survey in Gaofeng village, Guizhou Province, the species turned out to not only had been successfully hiding away from biologists in the subterranean darkness, but that it also represented the first in its whole order to be discovered underground in the country. It is described in the open-access journal ZooKeys.

(Tokyo Metropolitan University) Tokyo, Japan - Researchers from Tokyo Metropolitan University have shown that the environment-driven evolution of a unique ovipositor in the female fruit fly Drosophila suzukii may have caused coevolution of the male genitalia; new features were found to cause mechanical incompatibility during reproduction with similar species, impeding crossbreeding and isolating the species. The dual role of the female genitalia was found to trigger coevolution and speciation, a generic pathway which may apply to many other organisms.
