Dating techniques: Illuminating the past

Nature 520, 7548 (2015). doi:10.1038/520438a

Authors: Richard G. Roberts & Olav B. Lian

The technique of optical dating was first reported 30 years ago, and has since revolutionized studies of events that occurred during the past 500,000 years. Here, two practitioners of optical dating assess its impact and consider its future.

Optomechanics: Listening to quantum grains of sound

Nature 520, 7548 (2015). doi:10.1038/520441a

Authors: Ivan Favero

An optomechanical device has allowed quanta, or 'grains', of mechanical vibration to be counted by optical means. The system may open up new possibilities in acoustics and thermal engineering. See Letter p.522

Regenerative biology: Neuregulin 1 makes heart muscle

Nature 520, 7548 (2015). doi:10.1038/520445a

Authors: Katherine E. Yutzey

Three studies reveal that augmentation of a signalling pathway involving the growth factor neuregulin 1 and its receptor protein ERBB2 can promote the generation of muscle cells in zebrafish, mice and infant heart tissue.

Ecology: Shared ancestry predicts disease levels

Nature 520, 7548 (2015). doi:10.1038/520446a

Authors: Helen M. Alexander

Ecological factors such as host density are important predictors of disease incidence. But another key determinant may be the evolutionary history and relatedness of the host community. See Letter p.542

Australia Could Attain 100 Percent Renewables by 2050, Study Says

Yale Environment 360 - Tue, 04/21/2015 - 10:13

Australia could reduce its greenhouse emissions significantly and transition to an economy

Windy Hill wind farm in Queensland, Australia. predominantly fueled by renewable energy for very little cost, according to an analysis by the Australian National University and WWF. The country could generate 100 percent of its electricity from renewables and have zero net emissions by 2050 because wind and solar technologies have fallen rapidly in price in recent years and Australia is the world's sunniest and windiest continent. Any progress, however, will depend on the government's willingness to set clear, long-term policies and regulations encouraging renewable energy use, the authors note. Under conservative Prime Minister Tony Abbott, Australia's current climate action plan calls for only a five percent cut in emissions from 2000 levels over the next five years.
