Anyone with a little knowledge of biology and a sense of mischief will know that intentionally yawning in a public place can set off a chain reaction. But a newly-published study explores why children with autism are less vulnerable to the “sympathetic yawn.” A common theory is that the reason we yawn when we see […]
We all feel in control of our actions and thoughts – but as technology and biology begin to intertwine, what does this mean for our minds? Could technology be used to control our brains? [AsapSCIENCE]
The Leidenfrost Maze was designed and built by University of Bath undergraduate students Carmen Cheng and Matthew Guy to demonstrate the self-propulsion of Leidenfrost droplets at public outreach events and schools. The video was created by Carmen Cheng as part of her undergraduate project. [UniOfBathAV]
This 32-year-old man is apparently the first person with a missing lower limb to control a robotic leg with his mind. Deus? Ex: Human Revolution. Chapter 1 – Prologue. A team led by biomedical engineer Levi Hargrove at the Rehabilitation Institute of Chicago in Illinois reported the breakthrough last week in the New England Journal […]
The Float table is a matrix of “magnetized” wooden cubes that levitate with respect to one another. The repelling cubes are held in equilibrium by a system of tensile steel cables. It’s classical physics applied to modern design. Each handcrafted table is precisely tuned to seem rigid and stable, yet a touch reveals the secret […]
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. [Ted-Ed]
No time to read Stephen Hawking’s A Brief History of Time? In just two and a half minutes, Alok Jha explains why black holes are doomed to shrink into nothingness then explode with the energy of a million nuclear bombs, and then rewind to the big bang and the origin of the universe. [TheGuardian | […]
US researchers believe it’s possible to put all smells into 10 rough categories. But it remains difficult to objectively measure or even describe a smell. While we can do a relatively decent job of measuring light and color, or of measuring pitch and volume, scents are a trickier proposition. Although taste falls into five main […]
