Koalas move like a marsupial and climb like a primate

This Aussie icon has the koalafications of both marsupials and primates. Why This Matters: Koalas just might be the closest thing to primates in Australia. Australia’s cuddly koala seems to have evolved tree clambering abilities that rival those of the apes and monkeys that never made it to the continent. Technically a marsupial – bearing its young in a pouch-like kangaroos and wombats – the koala (Phascolarctos cinerus) has relatively long limbs with two thumb-like digits […] See more

Splitting hydrogen from water just got a whole lot cheaper and easier

Scientists have created hydrogen using only water, iron, nickel and electricity, and much cheaper than before. Why This Matters: This is a gamechanger for Australia’s transition to the hydrogen economy. Hydrogen-powered cars may soon become more than just a novelty after a UNSW-led team of scientists demonstrated a much cheaper and sustainable way to create the hydrogen required to power them. In research published in Nature Communications, scientists from UNSW Sydney, Griffith University and Swinburne University […] See more

No, an alcohol tax doesn't only punish the poor

A new study debunks the myth that imposing an alcohol tax drives less-wealthy, heavy drinkers to drink even more.
