Silicon nanoparticles trained to juggle light

Silicon nanoparticles based devices would allow to transmit, reflect, or scatter incident light in a specified direction, depending on its intensity. They could be integrated into microchips that would enable ultrafast all-optical signal processing in optical communication lines and the next generation optical computers.

Ocean acidification threatens cod recruitment in the Atlantic

Increasing ocean acidification could double the mortality of newly hatched cod larvae. Researchers quantified mortality rates of cod at conditions which the fish may experience towards the end of the century. They integrated results of two experiments in model calculations on stock dynamics. The scenarios showed that the recruitment could decrease to between one quarter and one twelfth of last decades’ recruitment — a strong call for action for fisheries management.

Do the tools to quantify addiction help to define it?

Understanding what counts as an addiction, and what can be done to address it is the work of researchers across many disciplines. But what tools are used to ‘measure’ addiction, and are these capable of legitimising an addiction or improving our knowledge of it?

Fossilized rivers suggest warm, wet ancient Mars

Extensive systems of fossilized riverbeds have been discovered on an ancient region of the Martian surface, supporting the idea that the now cold and dry Red Planet had a warm and wet climate about 4 billion years ago, according to new research.

For teens, feeling safe at school means increased academic success

Parents across North America are prepping their teens to head back to high school, hoping they will study hard to get straight A’s. But new research shows that good grades aren’t just based on smarts — high marks also depend on a student’s feelings of safety.

Whales in the desert?

In Cerro Colorado, located in the Ica Desert of Peru, sedimentary sequences dating back nine million years have been found to host the fossil skeletons of hundreds of marine vertebrates. In 2008, remains of a giant raptorial sperm whale, Livyatan melvillei, were discovered at this site. In September 2014, the same international team of researchers found a partial skeleton of a mysticete whale in a rock boulder.
