Potential Reasons Why Your Girlfriend Is Suddenly Horny

by Tracy Moore Contrary to age-old, legendary tales of stiff breezes and brushed-against boners, men do not have the monopoly on spontaneously induced horniness. Women, too, “turn horny” or “get a horn on” or “horn it up,” for as many varied and random reasons as men do. Sure, we may generally be too repressed to express it like sports commentators narrating our own horny memoir, but that doesn’t mean we are immune to the horn-inducing moments of life. Still, it appears to puzzle men when they witness a woman copping to her own horn identity. On one forum, a man … Continue reading Potential Reasons Why Your Girlfriend Is Suddenly Horny

Diverse data upend history of language’s evolution

Credit: adriensifre/Flickr) Posted by Karen Nikos-UC Davis New research could revise the history of how we think humans acquired language. Scientists have held up a gene that may affect speech and language, FOXP2, as a “textbook” example of positive selection on a human-specific trait. In a new paper in the journal Cell, however, researchers challenge this finding. In their analysis of genetic data from a diverse sample of modern people and Neanderthals, researchers saw no evidence for recent, human-specific selection of FOXP2. “We’re interested in figuring out, on a genetic level, what makes us human…” A paper from 2002 claimed there was a selective sweep … Continue reading Diverse data upend history of language’s evolution

Learning to Read the Brain’s Temporary Records

While molecular mind-reading remains the stuff of science fiction, our work brings us a step closer to filling the gap between experience and memory.  Kelsey Tyssowski THE FIRST DANCE at my wedding lasted exactly four minutes and 52 seconds, but I’ll probably remember it for decades. Neuroscientists still don’t entirely understand this: How was my brain able to translate this less-than-five-minute experience into a lifelong memory? Part of the puzzle is that there’s a gap between experience and memory: our experiences are fleeting, but it takes hours to form a long-term memory. In recent work published in the journal Neuron, my colleagues and I figured out how … Continue reading Learning to Read the Brain’s Temporary Records

Study finds how sex gives life meaning

Credit: Pixabay  by PAUL RATNER There may be more to sex than you think. Not only can it make you feel good physically, it can lift your spirits. In fact, it can give your life meaning, says a team of psychologists from George Mason University. They published a paper in Emotion that shows how sex one day will cause a greater sense of meaning in life and a more positive mood the next day. The scientists Todd Kashdan and his colleagues undertook this three-week diary study because they felt that “in theoretical models of well-being, sex is rarely discussed and in many seminal articles, ignored.” Their study involved … Continue reading Study finds how sex gives life meaning

New study reveals the science behind Ouija boards

Wikimedia Commons  by NED DYMOKE Ouija boards. You either love ’em or hate ’em… or you’re one of the undead and someone with one keeps calling you back up to chat, sort of like the paranormal equivalent of butt-dialing. Either way, it’s been immensely popular since its invention by Elijah Bond in 1890 thanks to its supposed ability to “talk to the dead”. Over a century later it’s become quite the pop culture staple. Untold thousands of spooked-out kids have toyed with it at sleepovers—and dozens of supposed demonic possessions have allegedly (key word: allegedly!) occurred because of it. But it turns out there’s a far more … Continue reading New study reveals the science behind Ouija boards

New studies illuminate mysterious connection between sleep and Alzheimer’s disease

Geralt via Pixabay  by STEPHEN JOHNSON The exact functions of sleep remain a mystery to scientists. Although studies suggest that a healthy sleep schedule helps people regulate their emotions, perform better on cognitive tasks, and even live longer, it’s still unclear exactly what the body is doing during sleep to bring about these positive effects. However, one recent hypothesis suggests the brain uses its downtime to run a ‘cleaning cycle’ during which it removes metabolic debris, like amyloid beta (A-beta), the main component of the sticky plaques found in the brains of people with Alzheimer’s disease. According to the hypothesis, poor … Continue reading New studies illuminate mysterious connection between sleep and Alzheimer’s disease
