Every time you inhale through your nose, olfactory receptors in your nasal passages enable your sense of smell to function. These receptors consist of protein complexes that help you detect chemicals floating in the air.

But research now shows that those types of receptors aren’t only found along your breathing passages. They’re all over the body in a wide variety of organs, and they influence what organs like your liver and intestines are doing.

Added to that, cancer cells possess their own collection of olfactory receptors that affect how they function. And those receptors, some researchers believe, might represent one of cancer’s vulnerabilities – and a key to destroying cancers with scents.

Fifty young scientists were bestowed Xplorer Prize in Beijing Saturday.

Prime numbers are one of the most basic topics of study in the branch of mathematics called number theory.

Primes are numbers that can only be evenly divided by themselves and 1. For example, 7 is a prime number since I’m left with a remainder or a fractional component if I divide 7 by anything other than itself or 1. 6 is not a prime because I can divide 6 by 2 and get 3.

On a late summer afternoon it can seem like sunlight has turned to honey, but could liquid—or even solid—light be more than a piece of poetry? Princeton University electrical engineers say not only is it possible, they’ve already made it happen.

In Physical Review X, the researchers reveal that they have locked individual photons together so that they become like a solid object.

“It’s something that we have never seen before,” says Dr. Andrew Houck, an associate professor of electrical engineering and one of the researchers. “This is a new behavior for light.”
