Throughout history we've blushed and called it la petite mort, the sting of pleasure, the balsamic injection, the flood of bliss?the list continues. But let's cut to the chase: I'm talking about ejaculation.It's almost seems as if some deep-seated Puritanical modesty compels us to semantically sidestep addressing this perfectly natural function. Perhaps we're just a bit bashful that it feels really, really good. It's not polite to discuss such scrumptious pleasures publicly.Humans ar
When we think of the organs that help humans stay alive under the water, the heart and lungs top the list. But there's another organ that deserves recognition as well, though few of us would think to name it. It's the spleen.Mammals have a unique response to having our faces engulfed by water. Our heart rate slows and peripheral blood vessels constrict, shunting blood to vital organs where it's needed most. At the same time, our spleens release a cache of red blood vessels held for this
When you hear the word ?nature,? you're likely to think of your last camping trip to a state park, or of grandiose landscapes with forests, lakes, and snow-capped mountains. You may remember the last trip to the beach and the variety of birds you saw while sunbathing. There are likely many images that pop into your head when you hear the word but the image of a city is likely not one of them. The City Nature Challenge hopes to change that.What is the City Nature Challenge and how did it star
Diamond is the hardest natural material, but now scientists have shown that it can bend and stretch, much like rubber, and even elastically snap back into shape ? even if it only happens with diamonds that are very small. Such flexibility could open up a wide new range of applications for diamond, the researchers say.Diamond is extraordinarily hard, meaning it excels at resisting any change to its shape ? that's why a diamond can cut through softer materials and will only be scratched by
The average cow needs cranial surgery like it needs a hole in the head, but for one ancient bovine, it appears that's exactly what the doctor ordered.Researchers describing a hole in the skull of a Neolithic cow say it's possibly the earliest example of veterinary surgery ? though it may have also been mere practice for performing the procedure on a human patient.Trepanation, or the act of intentionally making a hole in the skull, has a long history in our species (and it's still o
On April 19, 1971, the Soviet Union launched the world's first space station, Salyut 1. See how it happened in our On This Day in Space video series here.
NASA's Transiting Exoplanet Survey Satellite (TESS) is in space, but its science work won't start until June. Here's what the spacecraft will be doing until then.
Studying how flames burn in microgravity is helping scientists understand combustion. The insights learned could help reduce pollution here on Earth, according to a video released by NASA.
NASA's Transiting Exoplanet Survey Satellite (TESS) launched today (April 18) from Cape Canaveral Air Force Station in Florida, rising off the pad atop a SpaceX Falcon 9 rocket at 6:51 p.m. EDT (2251 GMT).
