What are some creepy scientific discoveries?
Answers
Answer:
Discovered over a century ago, it took 100 years before British scientists knew this was a living organism which went from green to red as sunlight hit it, which appreciably darkened the snow and ice, bringing on an unnatural melt.
The organisms now cover about half of the Antarctic, speeding up melting and calving, accelerating climate change and seemingly immune to interference.
Answer:
1. Pinpointing where fear lives in the brain
Fear is a pretty universal emotion. But where does it come from? And what’s it like to truly be fearless? Researchers tried to answer the first question in 2011, when they tested a human patient, known anonymously as SM, who did not experience fear. SM had lesions on her amygdala, a part of the brain thought to be key to our experience of fear. They exposed her to snakes and spiders, took her to a haunted house, and had her watch scary movies. She showed—and felt no fear. That settles it, the researchers thought—the amygdala is key to the human fear response
2.Blood of young mice rejuvenates old mice
There are a lot of different interpretations of vampires out there—some sparklier than others—but two things remain consistent: Vampires guzzle blood and they live forever. As it turns out, if you’re trying to stay young, you could do worse than start with the blood of young victims. Scientists interested in aging joined two mice together—one young, the other old—and studied the effects. Once its circulatory system was connected to that of a younger mouse, the old mouse experienced reversed aging in muscle and in the brain. Although it’s not quite time to start asking your kids for blood transfusions, researchers are keen to start clinical trials in humans.
