A Scientist Deploys Light And Sound To Reveal the Brain in Exquisite Detail

Lihong Wang creates the sort of medical technology you’d expect to find on the starship Enterprise. Wang, a professor of biomedical engineering at Washington University in St. Louis, has already helped develop instruments that can detect individual cancer cells in the bloodstream and oxygen consumption deep within the body. He has also created a camera that shoots at 100 billion frames a second, fast enough to freeze an object traveling at the speed of light.

Scientists Find This Key Factor May Contribute to Overeating

If you ever find yourself digging through the fridge looking for food when you’re not really hungry, it could be more than a lack of willpower that’s to blame. Scientists believe the phenomenon could be the result of a hormone deficiency in the brain.

Here’s Why Half of the Life You Experience is Over by Age 7

Here’s Why Half of the Life You Experience is Over by Age 7

Have you ever observed that time seems to be going by faster as you get older? There’s a reason that one summer seems to stretch out forever when you’re a kid, but zips by before you know it when you’re 30. That reason is perspective, as a gorgeous interactive visualization, by Austrian designer Maximilian Kiener, demonstrates. When you’re one year old, a year is literally forever to you — it’s all the time that you’ve ever known. But as you grow older, one year is a smaller and smaller fraction of your total life. It’s like watching something shrink in your rear view mirror.

Women’s Brains May Be the Most Vulnerable to Alzheimer’s

Women’s Brains May Be the Most Vulnerable to Alzheimer’s

Women’s brains might be more vulnerable to the degenerative effects of Alzheimer’s disease than men’s, causing them to decline in memory and cognitive function twice as fast, according to new research that could explain why women make up two-thirds of all diagnosed Alzheimer’s cases in the US.

The finding was presented this week at the 2015 Alzheimer’s Association International Conference (AAIC) in Washington, DC, with the team also noting that women tend to decline more dramatically than men in cognition, function, and brain size after they’ve been in surgery or under general anaesthesia.

New Found Manuscript Could Be Oldest Known Quran Copy

A 1,500-year-old parchment could be one of the oldest known copies of the Quran, possibly dating back to a time that overlapped with the life of the Prophet Muhammad, according to researchers who recently dated the manuscript fragments. The text underwent radiocarbon dating, which measured the age of the find’s organic materials. Researchers at the University of Birmingham, in the United Kingdom, found that the leaves of parchment date back to A.D. 568 and A.D. 645.

Mysterious Link Emerges Between Native Americans and People Half a Globe Away

This week, two major studies of the DNA of living and ancient people try to settle the big questions about the early settlers: who they were, when they came, and how many waves arrived. But instead of converging on a single consensus picture, the studies, published online in Scienceand Nature, throw up a new mystery: Both detect in modern Native Americans a trace of DNA related to that of native people from Australia and Melanesia.

NASA’s Three-Billion-Mile Journey to Pluto Reaches Historic Encounter

After a decade-long journey through our solar system, New Horizons made its closest approach to Pluto Tuesday, about 7,750 miles above the surface — roughly the same distance from New York to Mumbai, India – making it the first-ever space mission to explore a world so far from Earth.

We’re Not All Aging at the Same Rate, Researchers Say

How long we’ve been on the planet isn’t necessarily reflected in our biological age, an international team of scientists has found. According to a new study, some of us are ageing faster than others, and there can be significant variations in how run-down our bodies become as we develop as adults. The team looked at physiological markers in almost 1,000 38-year-olds, and while most had biological ages that roughly matched the number of birthdays they’d celebrated, some of the test subjects had bodies that appeared to be much younger or older, based on a series of medical examinations.
