There’s more to acing interviews than holding the vocal fry
A new study of vocal fry, a low razz in human speech, suggests job interviewees might want to hold the fry. But there's more to a job interview than a little vocal sizzle.

Stress and the susceptible brain
Some of us bounce back from stress, while others never really recover. A new study shows that different brain activity patterns could make the difference.

Separating wheat from chaff in gluten sensitivity
Some people who think they are sensitive to gluten might not be after all: Fermentable short chain carbohydrates, or FODMAPs, may be to blame in people with irritable bowel syndrome.

A slow heartbeat in athletes is not so funny
Endurance athletes often experience sinus bradycardia, a slow heartbeat. A new paper shows this effect may be due to changes in the “funny channel” of the sinoatrial node.
- Neuroscience
To pee or not to pee
Mice recognize others’ scents through proteins in urine, suggesting that mouse pheromones produce more complex behaviors than previously thought.
- Neuroscience
You smell, and mice can tell
A new study shows that the smell of a man causes stress in lab mice. The findings show scientists have yet another variable to control: the scientist.
- Animals
Caiman tears make a salty snack
An ecologist observed a bee and a butterfly hovering around a caiman, engaging in lacryphagous behavior, slurping up the crocodilian’s tears.
- Neuroscience
How brains filter the signal from the noise
Our brains can distinguish a single voice in the middle of a noisy street. A new study in ferrets shows how auditory systems might separate the signal from the noise.
- Neuroscience
Bingeing rats show the power of food habits
Rats allowed to binge on sweetened milk show a bad habit for food. But while food might change our habits, a bad food habit may not necessarily be an addiction.
- Psychology
That beard is only hot because it’s not cool
There’s more to facial hair than whether you can grow it. A new study shows that attractiveness increases when your style of facial hair is rare.

Males compete all the way to sperm shape
An association between the ratio of certain proteins in mouse sperm and sexual competition raises many questions about what exactly gives a sperm a good head.
- Neuroscience
Lost sleep could mean lost neurons
A new study shows we may not be able to make up for chronic sleep deprivation. The protein SirT3 might protect us against late nights, but all-nighters may produce neuron loss.
