Sex or food? Decision-making in single-cell organisms  

Unicellular diatoms are able to adapt their behavior to different external stimuli based on an evaluation of their own needs. In experiments, Seminavis robusta diatoms directed their orientation either towards nutrient sources or mating partners, depending on the degree of starvation and the need to mate.

Can humans drive economic growth, meet rising demand for food, energy and water, and make significant environmental progress? The short answer is 'yes,' but it comes with several big 'ifs.' New research shows that we can put the world on a path to sustainability if we make significant changes within the next 10 years.

Research assesses geographic distribution of new antibiotics following market introduction  

New study finds that between 1999 and 2014, only 25 new antibiotics entered the global market. The majority of antibiotics released in this time period originated from Japanese or US companies and were launched in Japan or the US. Of the 25 antibiotics, 18 treat community-acquired respiratory infections, 14 treat skin infections, and 12 treat urinary infections. Half treat infections caused by resistant bacteria, but none targeted Gram-negative bacteria, which cause most untreatable infections.

Unravelling the genetics of fungal fratricide  

Selfish genes are genes that are passed on to the next generation but confer no advantage on the individual as a whole, and may sometimes be harmful. Researchers have, for the first time, sequenced (or charted) two selfish genes in the fungus Neurospora intermedia that cause fungal spores to kill their siblings. Unexpectedly, the genes were not related to each other, perhaps indicating that selfish genes are more common than previously thought.
