By Tim O’Hara, Museum Victoria Over the past five weeks I led a “voyage of discovery”. That sounds rather pretentious in the 21st century, but it’s still true. My team, aboard the CSIRO managed research vessel, the Investigator, has mapped and sampled an area of the planet that has never been surveyed before. The RV … Read More

By John Long, Flinders University Palaeontologists and the famous Tin Man in The Wizard of Oz were once in search of the same thing: a heart. But in our case, it was the search for a fossilised heart. And now we’ve found one. A new discovery, announced today in the journal eLife, shows the perfectly preserved 3D … Read More

Milking male salmon- it’s all in the hand hold. A long time ago in a place not so far away, a young research scientist spent several weeks each colour-changing autumn ejaculating male salmon for their rich, milky sperm.

By Cindy Baker Lamprey and hagfish (known as cyclostomes or agnathans) are the only living jawless vertebrates. Over 360 million years old, lampreys swam past herds of drinking dinosaurs, and have survived at least four mass extinctions. The brain of the lamprey is believed to be the closest example of our primal vertebrate ancestors, and lampreys provide important insight into … Read More

Dr Michael PlankThrow the small fish back, so they can grow and reproduce. So goes conventional scientific wisdom, as well as most of the world’s fishing regulations.

Should we … Read More
