The debate about global warming "a mirage"?

That’s what three scientists, one from Denmark and two from Canada, say in a new paper: The entire debate about global warming is a mirage. The concept of ‘global temperature’ is thermodynamically as well as mathematically an impossibility, says professor at The Niels Bohr Institute, University of Copenhagen, Bjarne Andresen who has analyzed this hot …

Stick it where the sun shines:

A Swiss entrepreneur says his thin-film solar panels will provide power more cheaply than fossil fules within five years: Even though solar technology has made significant gains since the 1970s when it cost $100 per watt (now it’s $3 to $4 per watt), that sweet spot of beating out fossil fuels is $1 per watt. …

First quantum computer running commercial applications

D-Wave Systems Inc. says it will demonstrate it on February 13. But get this: This is the core of a new quantum computer to be unveiled by D-Wave Systems, says Steve Jurvetson, Managing Director of Draper Fisher Jurvetson, a leading venture-capital firm. “It is attached to a Leiden Cryogenics dilution fridge, ready to begin a …

Storing an entire image on a single photon

It gets into that whole wave/particle quantum thing: a team led by associate professor John Howell at the University of Rochester passed a single photon through a stencil bearing the letters UR. But since a photon is both a particle and a wave, as a wave, it passed through the entire stencil and thus captured …

Sometimes when they say "It’ll never work," they’re wrong…

…but sometimes, they’re right. Behold The Museum of Unworkable Devices.

Electrifying development:

Ball lighting may have been explained at last–and created artificially in the laboratory! Key segment: A more down-to-earth theory, proposed by John Abrahamson and James Dinniss at the University of Canterbury in Christchurch, New Zealand, is that ball lightning forms when lightning strikes soil, turning any silica in the soil into pure silicon vapour. As …

You go, professor!

Stephen Hawking is planning a trip into space for 2009, courtesy of Richard Branson at Virgin Galactic. I can’t think of anyone who deserves a free trip more.

Researching the glue that holds the universe together

Sometimes I think I’m a little too focused in these column on the practical applications of recent scientific research. That’s understandable, since it’s through technology and new ways of doing things that science impacts on our everyday lives. But underpinning all scientific advances is basic research: research conducted, not to enable us to make a …

Anti-fogging nanoparticles

Those of you who don’t wear glasses don’t know how lucky you are. I’ve been a contact-wearer now for many years, but from the time I was about five until I was almost thirty I wore glasses, and I the most annoying thing about them was their inclination to fog up the minute you came …

The Canadian Light Source

Given that the Canadian Light Source in Saskatoon produces light a million times brighter than the sun, you might well expect to be able to see it at night even from Regina. Or, upon visiting it in winter, you might think you would find thousands of sun-starved Saskatchewanians lying all around it on beach-towels in the snow, …
