Carbon nanotube transistors outperform silicon
For decades, scientists have tried to harness the unique properties of carbon nanotubes to create high-performance electronics that are faster or consume less power. Now, for the first time, University of Wisconsin–Madison materials engineers have created carbon nanotube transistors that outperform state-of-the-art…

The neurology of self-awareness
What is the self? How does the activity of neurons give rise to the sense of being a conscious human being? Even this most ancient of philosophical problems, I believe, will yield to the methods of empirical science. It now seems increasingly likely that the self is not a holistic property of the entire brain; it…

A Rocket to Nowhere (2005)
The Space Shuttle Discovery is up in orbit, safely docked to the International Space Station, and for the next five days, astronauts will be busy figuring out whether it's safe for them to come home. In the meantime, the rest of the Shuttle fleet is grounded (confined to base, not allowed to play with its spacecraft…

Speech Is 3x Faster Than Typing for English and Mandarin on Mobile Devices
With the ubiquity of mobile devices like smartphones, two new widely used methods have emerged: miniature touch screen keyboards and speech-based dictation. It is currently unknown how these two modern methods compare. We therefore evaluated the text entry performance of both methods in English and in Mandarin Chinese…

Why bad scientific code beats code following “best practices” (2014)
I've just read " The Low Quality of Scientific Code ", which claims that code written by scientists comes out worse than it would if "software engineers" were involved.

An Interesting SETI Candidate in Hercules
Although the presence of ET planetary-based life as we know life and don’t know it, is all, comparatively as, and less and in gradations more technologically and cognitively achieved or advanced than our species, such life, in mathematical and thermochemical terms, is a must on a vast in raw numbers but quite possibly…

Why cities keep growing, corporations and people die, and life gets faster
This is in complete contrast to companies. The Google boys in the back garage so to speak with ideas of the search engine, were no doubt promoting all kinds of crazy ideas and maybe having even crazy people around them.

Planet Found in Habitable Zone Around Nearest Star
Astronomers using ESO telescopes and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima b, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface. This…

Sad Trombone Exoplanet Reality Check
Some people on the internet are getting very excited at the (unconfirmed) reports of an "Earth-like" exoplanet orbiting Proxima Centauri , a mere 4.25 light-years away from Earth. If correct, the planet is orbiting in the liquid water zone around our nearest stellar neighbour and is of the same order of mass as the…
