Desertification, when fertile land dries into desert, is a global problem. According to Dr Steffen Bauer, an ecological expert at the Deutsches Institut für Entwicklungspolitik, as much as 40 per cent of the world is ‘dryland’. And that puts much of it in danger of desertification. Surprisingly, though fragile, these areas hold roughly 44 per cent of the world’s farms. They’re also called home by about 2 billion people, warn the editors of Governing Global Desertification.

Atoms may hum a tune from grand cosmic symphony
Researchers playing with a cloud of ultracold atoms uncovered behavior that bears a striking resemblance to the universe in microcosm. Their work, which forges new connections between atomic physics and the sudden expansion of the early universe, will be published in Physical Review X and highlighted by Physics.

Martian moons model indicates formation following large impact
Southwest Research Institute scientists posit a violent birth of the tiny Martian moons Phobos and Deimos, but on a much smaller scale than the giant impact thought to have resulted in the Earth-Moon system. Their work shows that an impact between proto-Mars and a dwarf-planet-sized object likely produced the two moons, as detailed in a paper published today in Science Advances.

The brain learns completely differently than we’ve assumed since the 20th century
The brain is a complex network containing billions of neurons, where each of these neurons communicates simultaneously with thousands of other via their synapses (links). However, the neuron actually collects its many synaptic incoming signals through several extremely long ramified “arms” only, called dendritic trees. Continue reading “The brain learns completely differently than we’ve assumed since the 20th century”
Depression negatively impacts heart and stroke patients
Depression, even when undiagnosed, can have many negative effects on cardiovascular patients, including poor healthcare experiences, more use of healthcare resources and higher health costs, according to preliminary research presented at the American Heart Association’s Quality of Care and Outcomes Research Scientific Sessions 2018, a premier global exchange of the latest advances in quality of care and outcomes research in cardiovascular disease and stroke for researchers, healthcare professionals and policymakers.
