How Scientists Know Our Human Ancestors Ate Insects  

Today, insect eating is on the rise. Did our ancestors chow down on the critters, too? (Credit: CK Bangkok Photography/Shutterstock) Anticipating food shortages in coming decades, some companies are touting insects as tomorrow's protein source. Entrepreneurs are jumping on board and chips made of crickets are hitting grocery shelves. But scientists advise caution: They say more research is needed on the environmental impact of rearing insects at an industrial scale. As sustain...

A Frank Look at Female Orgasms and Rabbits  

A very weak paper in PNAS has attracted some attention lately: An experimental test of the ovulatory homolog model of female orgasm The paper aims to be a test of the hypothesis that the human female orgasm is a kind of evolutionary relic from an earlier stage in evolution. In humans, ovulation happens on a monthly cycle and is not related to sexual activity. However, in some mammal species, such as rabbits, ovulation is triggered by sex (or copulation, as biologists say)

Rumbling 'Marsquakes' on the Red Planet are Mystifying and Exciting Scientists  

NASA's InSight lander has its seismic instrument tucked under a shield to protect it from wind and extreme temperatures. (Credit: NASA/JPL-Caltech) NASA's Mars InSight spacecraft landed on the Red Planet in November 2018. Scientists equipped the mission with a seismometer so they could learn how Mars releases seismic energy — that is, to get a feel for how the Red Planet rumbles. So far, InSight has recorded more than 100 seismic signals, and researchers are confident at least 21 o...

Astronomers Zoom in on a Galaxy 9 Billion Light-years Away Thanks to Gravitational Lensing  

(Credit: MIT/Image courtesy of the researchers) When even the most powerful telescopes can't capture the views you want, it helps to have natural magnifying glasses to rely on. In a paper published Monday in Nature Astronomy, researchers describe how they zoomed in to capture a young, star-forming galaxy roughly nine billion light-years away in X-ray light. To study such a distant galaxy, they used the fact that massive objects can warp space-time around them and magnify ligh...

Why Do We Have Eyelashes? New Study Says It's to Keep Our Eyes Moist  

Do eyelashes exist, in part, to keep our eyes from drying out? (Credit: KDdesignphoto/Shutterstock) Why do we have eyelashes? The answer might seem simple: Those thick hairs on the end of our eyelids simply exist to block intruding particles from landing on our eyeballs. And, in fact, that's what many scientists have hypothesized. It explains why camels evolved to have long lashes for wandering the dusty desert — and why our house pets, in comparison, have stumpy ones. ...

The bags, which have been around since at least 2006, are sometimes called "silken" sachets. They can be made from hemp, corn-based plastics, nylon or PET (polyethylene terephthalate).

Intense Stress Might Hurt Our Cells' Ability to Make Energy, Study Finds  

(Credit: Alliance Images/Shutterstock) For many, stress is an all-too familiar emotion. It can come from daily challenges, like juggling work and child care, or major life events, like getting divorced or losing a loved one. We all experience this stress differently — some people can't sleep, others stress eat, and still others develop debilitating anxiety. But our bodies may be responding to stress on a deeper level. Chronic stress and anxiety could disrupt how our cells pro...
