Scientists may have found a better way to spot early signs of dementia: our eyes

As our body’s central control center, the brain has to keep going at all costs. It makes sense that it’s surrounded by biological safeguards: a bony skull, a sack of tissue, and blood vessels that filter out most infectious bugs. When neurons start to decline—as some do naturally with age—the brain can even quickly rewire networks before we notice anything is amiss. But these same safeguards are a huge obstacle for scientists trying to study the brain’s decline—specifically dementia. Grey matter is excellent at adapting to the slow buildup of abnormal proteins, the cause of several forms of dementia , and it lacks the same pain receptors as the rest of our body. So by the time a patient starts becoming forgetful, or having trouble concentrating, the cellular damage is already substantial—and usually irreversible. In order to slow or prevent dementia, scientists will have to be able to spot it before cognitive systems collapse. Current diagnostic tools for Alzheimer’s, the most com...

Scientists Now Believe Quantum Entanglement May Apply to Time Itself

Bild
( TMU ) — The discoveries made over the last century by physicists studying quantum mechanics—some of which suggest that reality is only made certain by the presence of a conscious observer—is nothing short of mind-blowing. One particular concept, entanglement, was so out there that Albert Einstein called it “ spooky action at a distance ” and for many years refused to accept it as true.  But now, a new experiment has scientists believing that quantum entanglement doesn’t just apply to spatial gaps, but time itself. Einstein famously battled with physicist Niel Bohr over the predictions and theories of quantum mechanics, such as the wave function. He also corresponded with Erwin Schrödinger — yes, of Schrödinger’s cat — and in one of his 1935 letters, Einstein stated: “I know of course how the hocus pocus works mathematically. But I do not like such a theory.” The principle of entanglement held that it was impossible to independently describe two quantum systems that ha...

You Get More Introverted With Age, According to Science

Bild
Even though I’m a classic introvert , it was normal for me in my teens and early twenties to spend almost every weekend with friends. Now, in my mid-thirties, the perfect weekend is one with zero social plans. I’m not the only one who’s slowing down socially with age. Take, for example, my extroverted college friend who ran through her contact list, making phone calls to chitchat, every time she was alone in her car. She couldn’t be without human contact for even the 10 or 15 minutes it took to drive to the grocery store. These days, as a 30-something, she’s content to spend most nights at home with her family. I haven’t gotten one of her infamous calls in years. So what gives? Do we get more introverted as we get older? Probably, according to Susan Cain, author of the bestselling book Quiet: The Power of Introverts in a World That Can’t Stop Talking — and this is actually a good thing. Let me explain. Why We Become More Introverted With Age In a post on Quiet Revolution , Cain...
