Your own blood could become a mosquito's worst enemy
Mosquitos kill about 725,000 people a year... making them the deadliest animal in the world. Our own blood could kill them, thanks to a new study of an old drug.
Mosquitos kill about 725,000 people a year... making them the deadliest animal in the world. Over half of those are from malaria, a protozoan parasite that destroys red blood cells, which is spread by mosquitos in tropical and subtropical regions.
Researchers have found that taking ivermectin, a drug designed to prevent elephantitis, actually kills mosquitos when they bite a human. With high doses (300mg or more) of ivermectin, it killed mosquitos for up to 30 days. It's exciting news for researchers, who have been looking for more concrete evidence that the drug works before rushing it to the mass market. Ivermectin has been around since the 1980s but only has it fairly recently been used to study malaria. Studies have been performed using ivermectin since the 1980s, yet the recently published study in the Lancet Infectious Diseases journal appears to be the most conclusive.
Mosquitos, it has been argued, serve no real biological purpose on Earth. A 2010 study found that from an ecological standpoint mosquitos are only good at two things: spreading disease (which they excel at) and creating other mosquitoes. Aside from a few frogs and spiders going hungry for a few hours, we really wouldn't be missing that much.
The ability to speak clearly, succinctly, and powerfully is easier than you think
The ability to communicate effectively can make or break a person's assessment of your intelligence, competence, and authenticity.
The results come from a 15-year study that used ultrasound scans to track blood vessels in middle-aged adults starting in 2002.
- The study measured the stiffness of blood vessels in middle-aged patients over time.
- Stiff blood vessels can lead to the destruction of delicate blood vessels in the brain, which can contribute to cognitive decline.
- The scans could someday become a widely used tool to identify people at high risk of developing dementia and Alzheimer's.
What defines a dark horse? The all-important decision to pursue fulfillment and excellence.
When we first set the Dark Horse Project in motion, fulfillment was the last thing on our minds. We were hoping to uncover specific and possibly idiosyncratic study methods, learning techniques, and rehearsal regimes that dark horses used to attain excellence. Our training made us resistant to ambiguous variables that were difficult to quantify, and personal fulfillment seemed downright foggy. But our training also taught us never to ignore the evidence, no matter how much it violated our expectations.
