Wireless bicycle brake, a prototype on an exciting mission
Female sex hormones can weaken the ability of fish to protect themselves against environmental toxins
At this time, wireless networks are able to brake just one bike, but in the future, the technical elements will be further developed to regulate entire trains as they travel over the lines. In view of this, computer scientists are designing mathematical calculations to check such systems automatically. read more..

Female sex hormones can weaken the ability of fish to protect themselves against environmental toxins
It is well known that female sex hormones (estrogens) that end up in rivers and lakes, primarily via spillage from sewers and livestock farming, pose a threat to the environment. Some environmental toxins can also have the same impact as estrogens. One example of such substances are degradation products (metabolites) from the pollutant PCB. read more..
