Oxytocin slows down aging in lonely prairie voles A new study finds that giving isolated prairie voles daily injections of oxytocin prevents telomere shortening, a common sign of aging.

Loneliness ages you faster. But hormones can help! A recent study shows that oxytocin prevents cellular aging in lonely prairie voles.

Telling people it’s a placebo does not stop it from working After being given a placebo and viewing negative images, people felt less distress, even though they knew their treatment had no active ingredients.

Does giving a placebo require lying to a patient? This study concludes…no! Placebos still work even when the patient knows, at least for emotional distress.

Cortisol, not testosterone, can help you get a date Study finds that increased cortisol before, but not during, a speed-dating event makes men more popular with women. It depends on timing.

Scientists debunk what we knew about sperm movement New research finds we were looking at sperm all wrong. For 350 years, scientists believed sperm wiggled their tails side-by-side to create a whip-like motion. Using 3D technology, a study found sperm actually move by rolling around and spinning their heads like tops.

How would we establish a society on Mars? Humans are not built for Mars. Or rather, Mars isn't built for us. Understanding the sacrifices such a massive undertaking needs is important to its success.

We aren’t that far off from Mars colonies. But humans are not built for Mars. Or rather, Mars isn’t built for us, yet. Understanding the sacrifices such a massive undertaking needs is important to its success.

Short, Tall, or Average: It’s in Your DNA Over 700 different genes have been found to contribute some small amount to your adult height. The rare ones have a bigger impact than the common ones!
