Kissing Couples Share Resistance-Boosting Bacteria
The more you kiss you partner the more identical your mouth bacteria becomes. French kissing for 10 seconds will get the best results, according to a recent study.

It's fun to pucker up your lips and smooch with your significant other, but your make-out sessions may have a healthy twist. Mandy Oaklander of Time reported on a recent study that sought to know what kinds of microbes couples transmit when they kiss.
Remco Kort, Professor at the Netherlands Organisation for Applied Scientific Research, asked 21 couples to French kiss for 10 seconds as a part of his study. The participants' mouths were swabbed before and after they locked-lips. The results from this small batch of volunteers were that the bacteria in the mouths of couples were much more similar than that those of two strangers:
“Apparently, being with somebody for an extended amount of time and having a relationship leads to a similar collection of bacteria on the tongue.”
In order to test this hypothesis, one person was asked to drink probiotic yogurt and then kiss their partner. Researchers found that the new bacteria was transferred to their partner's mouth. Kort and his team of researchers found that the more often couples kiss, the more bacteria they shared (and that's a good thing):
“There are a number of studies that show if the diversity in bacteria increases—more different types of species—this is a good thing. If you look at it from this point of view, kissing is very healthy.”
Couples who kiss can build up resistances by exposing themselves to more microorganisms (around 80 million bacteria). Of course, you should know your partner, after all, there are some unsavory things that can be transmitted through kissing.
If you're looking to get the maximum amount of bacteria from your partner in a short amount of time, Kort recommends the most efficient way to do that is through a French kiss:
“French kissing is a great example of exposure to a gigantic number of bacteria in a short time. As many as 80 million in a period of just 10 seconds. Some establish themselves on your tongue, but a great many don’t.”

Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.
- There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
- CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
- Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
- Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.
Protected animals are feared to be headed for the black market.
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
