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.
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.
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 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.
Neuroscientists have identified an area of the brain that might give the human mind its unique abilities, including language. The area lit up in human, but not monkey, brains when they were presented with different types of abstract information.
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.
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.
A trio of Nao robots has passed a modified version of the “wise man puzzle” and in so doing have taken another step towards demonstrating self-awareness in robotics.
Birth order study: Researchers have found that the differences between first-borns and ‘later-borns’ are so small that they have no practical relevance.
One day after its historic flyby of Pluto, NASA’s New Horizons space probe has delivered eye-popping photos of the dwarf planet and its moons.
Video Source: AsapSCIENCE With the recent release of the movie, Self/Less, where Ben Kingsley’s wealthy and powerful character transfers his consciousness into the body of a much younger Ryan Reynolds for more longevity, there is a natural curiosity about whether this sort of thing is even remotely plausible. The curious guys at Science Asap explore that […]
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.
Gunpowder is the key ingredient, but as adjunct professor of chemistry John Conkling from Washington College in the US explains in this video, without chemistry, you wouldn’t have burning mixtures and without these you simply can’t have fireworks.
June 30, 2015 will officially be a bit longer than usual because an extra second, or ‘leap’ second, will be added. Here’s why…
