In the fundamentally fuzzy world of quantum mechanics, it can be difficult to keep clear memories, and that could be a problem for future quantum computers.
YOU would think that right after the big bang, the universe would have been pretty hot. In fact it looks like things were a lot cooler than you might imagine.
It sounds like a science fiction joke, but it isn't. What do you get when you turn an invisibility cloak on its side? A mini flying carpet.
The E8 root system consists of 240 vectors in an eight-dimensional space. These vectors are the corners of an eight-dimensional object called the Gosset polytope 4 21 represented here in two dimensions (Image: John Stembridge, based on a drawing by Peter McMullen)
Superconducting mirrors made of copper covered by a thin layer of niobium. These mirrors are able to store microwave photons up to one-tenth of a second (Image: Michel Brune)
The image on the left shows the glass ball’s “plop” as it enters the water. The ball on the right is coated with a hydrophobic layer that causes it to repel water, creating a bigger splash (Image: Lydéric Bocquet)
Reports that the bubble had burst for a form of cheap, table-top nuclear fusion may have been premature. Rusi Taleyarkhan, the physicist at the centre of a furore surrounding so-called bubble fusion, was last week cleared of scientific misconduct.
Gravity may be the force we're most familiar with, but it's also the one we understand with the least accuracy. Now, a quantum mechanical technique could help pin down the strength of gravity more precisely.
The race to build an exotic material with a negative refractive index for visible light has been won by a team of researchers in Germany. The demonstration could open the door to a new generation of optical devices such as superlenses able to see details finer then the wavelength of visible light.
New high-speed footage of the humble rubber band has treated physicists to a rare insight into the properties of elasticity, and discovered the truth about exactly why an elastic band recoils.
If you think we know all there is to know about water, think again. Scientists claim they have created a totally new alloy of hydrogen and oxygen molecules by splitting water.
Women told that female under-achievement in mathematics is due to genetic factors perform much worse on maths tests than those told that social factors are responsible.
An invisibility cloak that works in the microwave region of the electromagnetic spectrum has been unveiled by researchers in the US. The device is the first practical version of a theoretical set-up first suggested in a paper published earlier in 2006.
LEE SMOLIN is no magician. Yet he and his colleagues have pulled off one of the greatest tricks imaginable. Starting from nothing more than Einstein's general theory of relativity, they have conjured up the universe. Everything from the fabric of space to the matter that makes up wands and rabbits emerges as if out of an empty hat.
Computer simulations showed that dark matter should be densest at the centres of galaxies, like this one, but observations show it is constant over thousands of light years - supernovae could be to blame (Image: NASA/Hubble Heritage/AURA/STScI)
Studying Young Minds, and How to Teach ThemFor much of the last century, educators and many scientists believed that children could not learn math at all before the age of five, that their brains simply were not ready.
Insiders sell like there's no tomorrowThe stock market has mounted an historic rally since it hit a low in March. The S&P 500 is up 55%, as U.S. job losses have slowed and credit markets have stabilized.
Ahmadinejad says Obama must apologise to the Iranian people for BushPresident Ahmadinejad of Iran has adopted a hardline stance in response to diplomatic overtures from the Obama Administration, insisting today that the US President needed to show a "fundamental" change in policy if he wants to improve relations with Iran.
McCain: Our Economy's "Fundamentals are Strong"WOW he really doesn't have a clue. Maybe he means that the 1% that got richer. Their fundamentals are strong, not the rest of us.
Obama appeals to Latinos on economyBarack Obama, reaching out to crucial Latino voters, began airing new Spanish-language radio and TV ads today that assert that Republican John McCain is out of touch, capitalizing on his comment last week that the fundamentals of the economy remain strong.

OIL: Prices Won't Be Falling Anytime SoonAlthough some policy-makers have blamed producing countries for steadily rising oil prices, many experts say more fundamental factors are a growing demand-supply imbalance, a weak dollar, and market speculation.
Reasons I like College Women's Softball More Than Major League BaseballForget about those steroid injectin', money stealin', lollygagers called Major League Baseball, let's watch some softball.
Fundamentals, the Obvious Building Blocks for Your Business - Associated Content - Associated ContentThe fundamentals for any business can be traced back to that classic alliteration, "readin', ritin', 'rithmetic."
Dell concerns compounded by accounting messDell on Monday said it will delay filing its second quarter fiscal report due to an ongoing informal investigation by the Securities and Exchange Commission over previously disclosed accounting irregularities.
