How often is moon both full and closest to Earth?
Closest full moons recur in cycles of 14 lunar (synodic) months, because 14 lunar months almost exactly equal 15 returns to perigee (moon’s closest point to Earth). A lunar month refers to the time period between successive full moons, a mean period … Continue reading

Better way to turn ocean into fuel
UOW scientists have developed a novel way to turn sea water into hydrogen, for a sustainable and clean fuel source. Using this method, as little as five litres of sea water per day would produce enough hydrogen to power an average-sized … Continue reading

Simple theory may explain dark matter
Most of the matter in the universe may be made out of particles that possess an unusual, donut-shaped electromagnetic field called an anapole. This proposal, which endows dark matter particles with a rare form of electromagnetism, has been strengthened by … Continue reading

The experiment that first hinted at the existence of DNA
In the early 1900s, scientists were puzzled by the behavior of bacteria. They seemed to pick up the traits of their fallen comrades, but that wasn’t possible, right? In a simple experiment, Frederick Griffith showed that it was, through something … Continue reading
