Behavioural correlations of the domestication syndrome are decoupled in modern dog breeds
Scientists since Darwin have been intrigued by the simultaneous alteration of multiple morphological, physiological and behavioural traits across a wide range of domesticated animals, such as horses, pigs and dogs. For instance, reduced brain size, floppy ears, increased docility and hormonal changes are commonly seen in domesticated animals but not their wild ancestors. This phenomenon is known as the domestication syndrome, and the traits within this syndrome are assumed to change together in a correlated fashion during domestication. But surprisingly, whether or not any of these traits are in fact correlated has never been formally tested.

Mapping the ocean's unseen heroes, one microbe at a time
The picture of how climate change is impacting our ocean is often told via its larger inhabitants: scrawny polar bears, bleached coral, dwindling catch in fishing nets. But just as importantly, microscopic marine organisms play an essential role in our biosphere.

New core-shell catalyst for ethanol fuel cells
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and the University of Arkansas have developed a highly efficient catalyst for extracting electrical energy from ethanol, an easy-to-store liquid fuel that can be generated from renewable resources. The catalyst, described in the Journal of the American Chemical Society, steers the electro-oxidation of ethanol down an ideal chemical pathway that releases the liquid fuel's full potential of stored energy.

New approach optimizes use of future wave electricity generators during disaster
When hurricanes strike, loss of electricity ranks as one of the top concerns for relief workers. Blackouts lasting a week or more can hamper recovery efforts, shutter hospitals, threaten public health and disrupt transportation. The monthslong effort to restore power to Puerto Rico following the 2017 hurricane season has led to renewed interest in finding innovative ways to get affected power grids back online.

Proof of sandwiched graphene-membrane superstructure opens up a membrane-specific drug delivery mode
Researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences and Tsinghua University (THU) report a sandwiched superstructure for graphene oxide (GO) that transports through cell membranes. The discovery, published in Science Advances, opens up a membrane-specific drug delivery mode, which could significantly improve cytotoxicity effects over traditional drug carriers.

Evolving neural networks with a linear growth in their behavior complexity
Evolutionary algorithms (EAs) are designed to replicate the behavior and evolution of biological organisms while solving computing problems. In recent years, many researchers have developed EAs and used them to tackle a variety of optimization tasks.
