Studies Aren't Everything We Know: Some Drug Trials Never Get Published

Clinical trials are the basis of doctors’ understanding of whether a drug is safe and effective. But the trials that get published aren’t the whole story: Those that aren’t favourable to the pharma companies’ bottom line can often get swept under the rug.


If We Actually Followed The Paleo Diet, We'd Be Cannibals

The so-called palaeodiet, and now even the palaeo-epigenetic diet, has come under a lot of scrutiny of late for making wild and unsubstantiated claims and for being downright dangerous to our health. I think it’s fair to ask if we’re serious about the palaeolifestyle, then just how far are we prepared to take this obsession with our Stone Age heritage and its claimed benefits?


'Clinically Tested' Skin Care Products May Not Be Tested At All

Lotions and other skin care products often boast that they are “clinically tested” or “dermatologist tested”. These terms don’t refer to the same kinds of clinical tests that a drug would undergo, and in many cases probably mean nothing.


How McDonald's Destroys The Good Bacteria In Your Gut

When Morgan Spurlock famously spent a month eating large portions of McDonalds for the purposes of his documentary Supersize Me, he gained weight, damaged his liver and claimed to have suffered addictive withdrawal symptoms.

Winter is approaching. Your nose is stuffy and you feel a cold coming on. You head to the pharmacy to find an aisle full of cold and flu tablets.


What Science Tells Us About Brain Training Games

There has been excitement among researchers in recent years that playing certain video and computer games may strengthen core components of cognition, helping us to make quicker decisions, think more fluidly, and avoid harmful distractions.


The Biggest Concerns About Genetically Modified Food Aren't Really About GMOs

Everyone from Greenpeace to the Food Babe rails against genetically modified ingredients, and there are frequent campaigns to ban genetically modified organisms (GMOs) or require changes to labelling laws. But the laser focus on GMOs is misguided, because most of the concerns people raise about them aren’t really about GMOs.


Why Tracking Calories From Exercise May Sabotage Weight Loss

I’m a huge fan of tracking calories in order to lose weight. This process is quite powerful…with one exception. Here’s an eerie case where merely thinking about calories may nullify your progress.


When Memory Lapses Mean You Might Have Alzheimer's

From time to time, we all misplace our keys or forget someone’s name, at least for a few minutes. This may prompt worry about “getting Alzheimer’s”, particularly if we have an older parent who was afflicted by this disease.


How To See The Hubble Space Telescope From Australia

The Hubble Space Telescope (HST) has now been in orbit for 25 years and this achievement has been a wonderful excuse to pour over the telescope’s beautiful imagery, to consider its valuable contribution to science, to remember its troubled beginnings and applaud its stellar success. But one way, I’m hoping to mark the telescope’s anniversary is to hunt for it in the night sky.
