WHO declares swine flu pandemic

June 12, 2009

The World Health Organization (WHO) has declared a global flu pandemic, meaning the swine flu virus is spreading in at least two regions of the world.

It has spread to 74 countries. It is the first flu pandemic in 40 years; the last in 1968 killed about one million people. However, the current pandemic seems to be moderate and causing mild illness in most people.

White roofs, streets could curb global warming

September 18, 2008

If the 100 largest cities in the world replaced their dark roofs with white shingles and their asphalt-based roads with concrete or other light-colored material, it could offset 44 metric gigatons (billion tons) of greenhouse gases, a study by Lawrence Berkeley National Laboratory and UC Berkeley shows.

White surfaces would also lower the cost of air conditioning by up to 20% in hot months and cool a city by… read more

The White House said Friday that publications from taxpayer-funded research should be available to you, but only after a year’s delay.

“The Obama Administration is committed to the proposition that citizens deserve easy access to the results of scientific research their tax dollars have paid for,” the memo said.

But that doesn’t mean fast access. And the policy would, strangely, only apply to Federal agencies with more… read more

White dwarfs could be fertile ground for other Earths

March 31, 2011

White Dwarf

University of Washington associate professor of astronomy Eric Agol has proposed that potentially habitable planets orbiting white dwarfs could be much easier to find than other exoplanets located so far.

White dwarfs, cooling stars believed to be in the final stage of life, typically have about 60 percent of the mass of the sun, but by volume they are only about the size of Earth.… read more

White dwarf star throws light on constant of Nature

University of New South Wales (UNSW) physicists are studying a distant star where gravity is more than 30,000 times greater than on Earth to test their controversial theory that α (alpha) — also known as the fine-structure constant — is not a constant.

“If alpha [the fine-structure constant] were bigger than it really is, we should not be able to distinguish matter… read more

A computer science professor at Amherst College has conducted experiments to test the speed of a quantum computing system (from D-Wave) against conventional computing methods.

“Ours is the first paper to my knowledge that compares the quantum approach to conventional methods using the same set of problems,” says Catherine McGeoch, the Beitzel Professor in Technology and Society (Computer Science) at Amherst.

Whether or not God plays dice, I do

Scott-Aaronson

Physicist Scott Aaronson is offering a US$100,000 award for a demonstration, convincing to him, that scalable quantum computing is impossible in the physical world. “This award has no time limit other than my death, and is entirely at my discretion (though if you want to convince me, a good approach would be to convince most of the physics community first),” he says.
