Deadly scorpion venom is being used to create new eco-friendly pesticides as some types of venom are harmful only to insects and unlikely to harm larger creatures.
Deadly scorpion venom is being used to create new eco-friendly pesticides as some types of venom are harmful only to insects and unlikely to harm larger creatures. "Scorpions are notorious for harnessing a powerful, debilitating venom in their tails. Some species harbor venom potent enough to kill a human being. But other parts of that venom cocktail are only intended for other insects--and only affect other insects. If the strains of venom that do so were to be isolated, that could be a pretty potent insecticide, right? One researcher thought so--so he concocted a brand new, ecologically safe pesticide from the deadly venom found in scorpions. While 'ecologically safe pesticide made from scorpion venom' is a phrase that appears to be chock full of contradiction, it could actually mark an important advance for agriculture and human health. This is why: as of now, the ag industry uses pyrethroids almost exclusively, which work by penetrating insect bodies, attacking their nervous systems, and finally causing paralysis and death. Problem is, these compounds ‘lack specificity,’ according to Science Daily, and the compounds pose a danger ‘to the environment, livestock and humans.’"
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).
