Victims were pale and frail, blood stained their mouths, and after their death, their family members wasted away too, as if they were being fed upon. In the 18th and 19th centuries, if someone had those symptoms they may have been a vampire… or they may have just been infected with Mycobacterium tuberculosis (MTB), the
We're familiar with ants as picnic-skimming and foot-biting pests, but just below the soil's surface, ants live surprisingly complex and intricate lives. The leaf cutting ants, or leaf cutters, live in a way that's particularly alien to us, as the dominant herbivore (or perhaps “fungivoreâ€) of South American rainforests. Ant colonies as superorganisms Rather than
It wasn't that long ago when scientists discovered the key to what makes us who we are. We're familiar with deoxyribonucleic acid (better known as DNA) as the molecule responsible for inheritance, but it was only discovered 63 years ago. It's astounding that we've come so far in only a few decades. Rapid advances in
Earlier this spring, Buzz the Bee disappeared from Honey Nut Cheerios boxes in Canada. Burt's Bees dropped the letter B from its lip balm products. Are these clever marketing ploys? Perhaps, but they were designed with a more noble purpose in mind: to raise awareness of disappearing honeybees. And, it's not just companies with apian
Why was six afraid of seven? Because their colors clash, of course. And seven can be a bit of a jerk. We tend to trust our own perceptions, and assume others share the same reality we experience. But for about 1 in 23 people, such things as friendly or specifically-colored numbers are just another aspect
Camels are rightfully known as “the ships of the desert†because of their impressive ability to carry up to 500 lbs on their back! While camels seem to conjure up images of pyramids and arid, desolate seas of sand dunes, they weren't always the quintessential desert-dwelling beasts that they are today. Camels actually originated in

This March, Netflix released its second season of its Marvel superhero drama, Daredevil. Daredevil features Matt Murdock, a lawyer who moonlights as the titular vigilante defender of Hell's Kitchen, who also happens to be blind.

Have you ever walked past a restaurant around lunchtime and found the smell alone was good enough to stop you in your tracks and have you speeding in to buy something to eat? For me, it's the smell of southern barbecue. At first it's the smoke billowing out of the kitchen that tickles your nose
I was always dimly aware of elephant poaching for ivory, but it didn't alarm me until I spent a year working as a tropical ecology research assistant in central Africa. I was in Gabon, a heavily forested small country in the heart of the Congo basin on Africa's west coast. Gabon is home to roughly
Welcome to Star Wars week here at the Athens Science Observer. To help celebrate May the 4th – Star Wars Day – we wanted to take a look at the real life science of that galaxy far far away. “Midi-chlorians.†For many Star Wars fans, this word alone can set off rage-induced rants. The Prequel
Alexander Fleming's discovery of penicillin in 1928 has been heralded as one of the most monumental medical discoveries of all time. Amazingly, this discovery was entirely accidental. After returning from a long vacation, Fleming noticed that a culture of Staphylococcus aureus was contaminated with mold. After observing the culture under a microscope, he found that
