A new human sex hormone that has been found in men could lead to the development of the male birth control pill, researchers have said.
A new human sex hormone that has been found in men could lead to the development of the male birth control pill, researchers have said. "Gonadotropin-inhibitory hormone (GnIH)—first identified in birds about a decade ago—was recently discovered in the hypothalamus of the human brain. The hypothalamus produces hormones that regulate sleep, sex drive, body temperature, and more. GnIH suppresses another hormone—gonadotropin-releasing hormone (GnRH)—which spurs the release of additional hormones, which get the body for sex and reproduction. So scientists cautiously suggest that contraceptives based on the newfound hormone could someday be possible. ‘That is an idea we've toyed with,’ said study co-author George Bentley, a biologist at the University of California, Berkeley. But ‘we don't know enough about it yet’
How a cataclysm worse than what killed the dinosaurs destroyed 90 percent of all life on Earth.
While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.
A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.
We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.
Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.
Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
