Small drop in sea level had big impact on southern Great Barrier Reef

University of Sydney researchers have analysed samples from One Tree Reef in the southern Great Barrier Reef and discovered a dramatic slow down following a small fall in sea level.The idea that coral reefs have formed over millennia in a continuous process has been challenged by a study of the southern Great Barrier Reef.

Climate affects the development of human speech

This map shows the distribution of languages with complex tone (red dots) and without complex tone (blue dots) in the Phonotactics Database of the Australian National University. Darker shading on map corresponds
to lower mean specific humidity.An interesting question, one that linguists have long debated, is whether climate and geography affect language. The challenge has been to untangle the factors that cause sounds to change.

Early human ancestors used their hands like modern humans

New research suggests pre-Homo human ancestral species, such as Australopithecus africanus, used human-like hand postures much earlier than was previously thought.

'Bulletproof' battery: Kevlar membrane for safer, thinner lithium rechargeables

Gigantic ring system around J1407b much larger, heavier than Saturn's

Artist's conception of the extrasolar ring system circling the young giant planet or brown dwarf J1407b is shown. The rings are shown eclipsing the young sun-like star J1407, as they would have appeared in early 2007. The best fit model is consistent with a system of at least 30 rings, and there are gaps where satellites ("exomoons") may have already formed.Astronomers at the Leiden Observatory, The Netherlands, and the University of Rochester, USA, have discovered that the ring system that they see eclipse the very young Sun-like star J1407 is...
