When we make a recording of our own voice then play it back, we are hearing it more or less as other people do. The sound waves travel as a series of vibrations through the air and meet our ear drum. The ear drum in turn sets three tiny bones vibrating – the incus, malleus and the stapes and they send vibrations into the cochlea. The cochlea translates the vibrations into nerve signals and those are sent to the brain. Why then does that sound so different to what we perceive as our own voice?
Jade bi (discs), from China, that resemble modern-day CD’s or donuts, and date to the late Neolithic Period, Liangzhu culture (ca. 3300-2250 BC) remain a mystery. Researchers at the Smithsonian’s Freer and Sackler galleries in Washington, D.C., are among those who have studied the bi.
Is a broken heart a simply abstract concept or their real physical effects on the body and the brain.
A NASA spacecraft slated for launch in September will fly to the Moon to investigate the tenuous lunar atmosphere. Researchers hope “LADEE” will solve a mystery that has been puzzling them since the days of Apollo.
Is personalized medicine for individual bodies in our future? Possibly — with the use of stem cells, undifferentiated cells with the power to become any tissue in our bodies. Craig A. Kohn describes the role of these incredible, transforming cells and how scientists are harnessing their medical potential.
The Norwegian University of Science and Technology in Trondheim has released a study suggesting that psychedelic drugs could have no widespread long term psychological effects. The team analysed the drug use habits and mental health history of thousands of American users in the study, and found that there was little evidence of long-term chronic mental health problems.
According to the September issue of the French magazine ’60 Million Consumers’, some electronic cigarettes may emit the same levels of formaldehyde (a carcinogen) as other conventional cigarettes.
Sometimes, Earth mimics a supernova, producing a Terrestrial Gamma-ray Flash from the tops of thunderstorms. A new lightning sensor on the International Space Station could solve the mystery of these energetic bursts.
Researchers Rajesh Rao and Andrea Stocco from the University of Washington have connected two human brains together for the first time, allowing one subject to control the other’s finger on a keyboard remotely, through the power of thought.
Basically nanotechnology is engineering or science at the nano scale. That is one-thousandth millionth of a metre. Pretty small, but not for modern science. It’s actually a relatively large range which encompasses anything from semi-conductor physics to microbiology and nano fabrication.
Lightning strikes kill about 24,000 people worldwide each year, and about 240,000 people are injured by lightning and survive. Here’s what you should do to survive a lightning strike.
Need fast internet? Go to space! That’s right– Nasa is about to launch super fast, laser-powered wifi off planet. Trace explains what the speedy connection will be used for.
This is the second part of a three-part miniseries on the shape of the universe. Could the universe be curved? What is curvature, anyway? What is the cosmological principle? And is the universe maybe some sort of hyperbanana?
This is the first part of a three-part miniseries on the shape of the universe. Is the universe infinite? Does it have an edge? In this part, we will talk about the possibility of a flat, finite universe without edge.
The etymology of the word magnet likely comes from naturally occurring lodestones (naturally occurring mineral deposits with magnetic properties) found by the ancient Greeks around the city of Magnesia. Likely thought of as witchcraft at the time, we now know that magnetism itself is due to unpaired electrons at a sub atomic level.
