2:25 AM | Shark Attack 2: Revenge of the Tabloid Headline Writer
When I was Sydney last October, preparing for the IUCN World Parks Congress with the French marine protected areas agency, this headline above was splashed in similar formats across several Australian newspapers. Shark scientists were kept very busy responding to misinformation, stupidity and downright dangerous reporting in the Australian spring and summer – and this headline (and […]

1:01 PM | 340,000 Miles @ Over 51 m.p.g.
As I move now to two-day weeks as an NC Zoo Society employee, I turn over keys to the Society's 2010 gray Toyota Prius, with the odometer up close to 140,000. My prior company car was the Society's tan 2004 Prius (sold to me in 2003, the first of those later-to-be-named "Motor Trend Car of the Year" autos sold in Asheboro). I drove it over 201,000. Because they are computers on wheels, I know they got a combined 51-plus m.p.g. [Estimated gasoline savings - my 2003 - 2015 mileage: 6,800 gallons] […]

6:36 PM | FDA struggles to define what “natural” means for food labels
After decades of debate there remains no generally accepted definition of a “natural” food product. Despite a gamut of products with the label prominently displayed, it has caused a headache in lawsuits for the government who have yet to define “natural”. According to new research, while regulatory agencies have refused to settle the issue, they […]

2:34 PM | Komodo Dragons: Their Bite is Worse than Their Bark
By Shelly Sonsalla Komodo Dragon. Image by Arturo de Frias Marques on Wikimedia. Komodo dragons are the world’s largest living lizard and can be found only on select islands in the Indonesian archipelago. These massive lizards can grow to be 10 feet in length and up to 150 pounds! Their natural prey includes wild boars, deer, and water buffalo—animals which may outweigh them by several hundred pounds. So how does a lizard, even such a large one, manage to take down prey so […]

10:52 AM | Can Neuroscience Teach Us About Winemaking?
Modern winemakers may have erred when they switched to producing high alcohol wines. According to a new paper, from Spanish neuroscientists Ram Frost and colleagues, a low alcohol content wine actually produces more brain activity in 'taste processing' areas than more alcoholic varieties do. But what does the brain really have to say about Beaujolais? Can scanning help us pick a Sauvignon? Will neuroimaging reveal the secret to a good... er... Nero d'Avola? In their paper, publishe
