Researchers have helped discover why the inhabitants of Madagascar speak Malagasy, a language otherwise unique to Southeast Asia and the Pacific — a region located at least 6,000 km away. An international research team has identified that ancient crop remains excavated from sites in Madagascar are of Asian species.

Scientists working in the Gulf of Mexico have found that contaminants from the 2010 Deepwater Horizon oil spill lingered in the subsurface water for months after oil on the surface had been swept up or dispersed. In a new study, they detailed how remnants of the oil, black carbon from burning oil slicks and contaminants from drilling mud combined with microscopic algae and other marine debris to descend in a ‘dirty blizzard’ to the seafloor.

Research has revealed that a molecule involved in fish reproduction activates the brain via the nose. The pheromone is released by female zebrafish and sensed by smell receptors in the noses of the males. The neural pathway and brain areas involved in transforming this molecular messenger into courtship behavior in fish were also identified by the researchers.

The water around Antarctica has not seen the atmosphere for centuries, since long before the machine age. New observations and model simulations suggest this may be the last place on Earth to feel climate change.

The fate of the world’s richest biodiversity of salamanders and newts is in the hands of pet owners across North America, warns a researcher, due to the threat of salamander chytrid disease that infects both salamanders and newts with near total lethality.

Researchers have engineered a hydrogen-producing enzyme in the test tube that works as efficiently as the original. The protein – a so-called hydrogenase from green algae – is made up of a protein scaffold and a cofactor. The latter is the reaction center where the substances that react with each other dock. When the researchers added various chemically synthesized substances to the protein scaffold, the cofactor spontaneously assembled.

The regulated cultivation and trade of cannabis for recreational use is permissible on the basis of states’ positive human rights obligations. Pleas for the regulated cultivation and trade of recreational cannabis are often based on arguments related to individual and public health, the safety of citizens and the fight against crime: the so-called positive human rights obligations. To date, however, no study has been carried out to find out what the legal implications of legalizing cannabis would be.

May 8, 1945: German forces in Norway have surrendered, and after five long years of occupation, the country is finally free. Suddenly, 30,000 Allied troops had to disarm 350,000 German soldiers, and deal with huge stockpiles of German bombs, guns and ammunition along Norway’s 2500-km-long coast. It was a nightmare assignment, especially the bombs. So the Norwegians did what they often did in times of crisis: they turned to the sea.
