What Makes A Popular Science Video On YouTube

Hundreds of hours of video are uploaded to YouTube every minute, and hundreds of millions of hours are viewed daily, including many that cover areas of science. Despite this, if you want to use YouTube for science communication, reaching an audience is not always guaranteed.


Electric Vehicle Makers Need To Agree On Standards

Standards are a key part of technical progress and for the increased use of renewable energy. Solar power provides an obvious example — if a photovoltaic unit is used to put power back into the electricity grid, then the power needs to satisfy the standards for the grid in terms of voltage, cycles-per-second, and so on.


Why Aren't There Any Human Doctors In Star Wars?

Though set “a long time ago in a galaxy far, far away,” it isn’t hard to see in the Star Wars films a vision of our own not so distant future. But Anthony Jones, a physician with a long background in health care technology development, sees the Star Wars vision of medicine’s future as sheer fantasy. Specifically, he is struck by the dearth of doctors – at least human ones. “In Star Wars,” he says, “there are no people practicing medicine.

There is a side to the Ebola crisis that, perhaps understandably, has received little media attention: the threat it poses to our nearest cousins, the great apes of Africa. At this moment in time Ebola is the single greatest threat to the survival of gorillas and chimpanzees.


Morning Haze: Why It's Time To Stop Hitting The Snooze Button

It’s 6:30AM and after a long holiday break, your alarm clock is insistently telling you it’s time to get out of bed. For many people — me included — the automatic reaction is to hit the snooze button, often more than once.


The Rabbits Of Christmas Past: A Present That Backfired For Australia

On Christmas Day 1859, the Victoria Acclimatisation Society released 24 rabbits for hunting, to help settlers feel more at home. Given the millions of dollars in damage to agricultural productivity that ensued, as well as the impacts on biodiversity as the rabbits bred and spread to cover 70 per cent of the continent, this could be seen as Australia’s worst Christmas present.
