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?

British scientists are convinced they have found proof of alien life, after they collected strange particles from the edge of Earth’s atmosphere.
Io – Jupiter’s innermost Galilean moon – is the most geologically active body in the Solar System. With over 400 active volcanic regions, plumes of sulfur can climb as high as 300 miles above the surface. It is dotted with more than 100 mountains, some of which are taller than Mount Everest. In between the volcanoes and mountains there are extensive lava flows and floodplains of liquid rock.
Is a broken heart a simply abstract concept or their real physical effects on the body and the brain.
The energy of comets smashing into Earth billions of years ago could have generated life out of the building blocks of life that those extraterrestrial objects brought, according to new experiments published in a peer-reviewed study.
Scientists develop world’s first self-healing elastomer, a plastic that can be cut in half and then repair itself without any intervention.
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.
There are no editing tricks in the video. All of the reactions that you see are uncut and play at the original speed.
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.
Magic mushrooms have more to offer than a good trip: new research shows they may help treat severe forms of depression. But a prominent researcher in the UK says his work is being stymied by the government. Laci Green looks at this fungal fix for a debilitating, sometimes deadly disease.
Scientists from the British Antarctic Survey have found life in mud samples at the bottom of a sub-glacial lake in Antarctica. They found microbes dating back almost 100,000 years as well as organisms previously unknown to science. The research team from the British Antarctic Survey and the universities of Northumbria and Edinburgh made their astonishing […]
A nuclear accident devastated the region near Chernobyl, Ukraine, on April 26, 1986 leaving behind a 2,600 km² exclusion zone where some 350,000 people were evacuated. This vast area, where time has stood still ever since, is springing back to life with wildlife. The evacuation of the human population has created a unique wildlife refuge which has seen an increase in biodiversity.
