New research shows that young fish are eating tiny pieces of plastic instead of their regular food — with potentially devastating consequences.

A study published this month in the journal “Science” explains that juvenile perch larvae appear to be eating microplastics in place of their usual food sources, like free-swimming zooplankton. This hinders fish development, leaving them more susceptible to predators.

Microplastics — plastic particles that measure below 5mm — infiltrate our environments as a result of litter, such as plastic bags, packaging and other materials, that eventually end up in the sea. Microbeads — tiny plastics often found in health products, such as face scrubs and even some toothpastes — represent another major source of pollution. For this reason, a number of governments have either banned or are considering banning microbeads.

La Red de Políticas sobre Energías Renovables para el Siglo 21, muestra que las energías renovables se han establecido firmemente como fuentes principales y competitivas de energía, en muchos países de todo el mundo, estrechando la brecha entre el tener y el no tener energía.

El 2015 fue un año récord para la instalación de energías renovables.

Due to a breeding boom over the past few years, giant pandas are making a strong recovery. Some experts argue that the species should be removed from the critically endangered list — but is it too soon?

This comes as the International Union for the Conservation of Nature undertakes an official reassessment of the panda’s status. The Swiss-based organization uses a seven-point scale to gauge the risk facing animal populations.

A radical new process that allows hydrogen to be efficiently sourced from liquid formic acid could be one step forward in making the dream of hydrogen-powered cars an economic reality.

Using formic acid to produce hydrogen has never been considered viable because it requires high temperatures to decompose and also produces waste by-products.

But the University of Melbourne's Professor Richard O'Hair has led an international team of scientists in designing a molecular catalyst that forces formic acid to produce only hydrogen and carbon dioxide and at a low temperature of only 70°C.
