A Single 10-Second Kiss Can Transfer 80 Million Bacteria

Kissing is disgusting: A poorly choreographed ritual of bad breath, awkward eye contact, and slobbery after-drool. Now, to make it even worse, a new study from the Netherlands has determined how many cooties move from one mouth to another during your basic smooch. And it’s A LOT.


Bacteria Have Been Hacked To Work Like Tape Recorders

You might not think a lone E. coli bacterium has much in the way of memory. But now, researchers have hacked their DNA so that they can store memories of their environment — working much like an old tape recorder.


How The Bugs In Our Buildings Could Actually Make Us Healthier

University of Oregon researchers Jessica Green and G Z ‘Charlie’ Brown call it the Pickle Box. This former walk-in storage unit for pickles, remodelled into an enclosed climate chamber, is helping scientists understand how people shed their own ‘microbial cloud’ in a built environment.


Can You Really Bust A Gut From Eating Too Much At Once?

Although extremely rare, some people actually have ruptured their stomachs after eating too much, and, perhaps not surprisingly, many did not survive.


How Many Undiscovered Blood Groups Are There?

You may think that you know your blood type, but did you know that there are in fact 35 blood group systems in humans? These include well-known systems such as ABO and the Rh system (formerly known as ‘Rhesus’).


The Thoughts Of Locked-In Patients, Visualised

These aren’t Second Life punks — they’re visualisations of what people with locked-in syndrome think, and they could help us communicate with people who can’t respond physically or verbally.


Inside The Science Of Sharing Rare Blood

His doctor drove him over the border. It was quicker that way: if the man donated in Switzerland, his blood would be delayed while paperwork was filled out and authorisations sought.


How Much Coffee You Need Is A Genetic Trait

For some, three double espressos is barely enough to get them out of bed; for others, the whiff of weak latte is enough to have them jittering. Now it turns out that those differing reactions are genetic.


The Many Ways We're Using Mutant Mosquitos To Eradicate Disease

Mosquitos suck. It’s not just because of those itchy red bites we all get in the summer, either. Mosquitos suck because they’re the deadliest animals on the planet, and none of our classic strategies from combatting the threat seem to be working. That’s why we’re turning the mosquitos against themselves.


The Quest To Resurrect An Extinct Animal Without Cloning

Before there was the cow, there was the auroch, a sinewy beast that roamed Eurasia by the millions. And over thousands of years, humans bred the creature into the millions of milk-and-steak-machines we have today. The last auroch, however, died in the 17th century. A group of scientists now want to bring back the auroch by selectively breeding modern cows — domestication, but in reverse.
