Scientists have found that a star that exploded in 1979 is as bright today in X-ray light as it was when it was discovered years ago, a surprise finding because such objects usually fade significantly after only a few months.
Physicists have created the state of matter thought to have filled the Universe just a few microseconds after the big bang and found it to be different from what they were expecting. Instead of a gas, it is more like a liquid.
First in novel optical materials: researchers at Ames Lab made 3-D photonic band gap crystals 4mm square and 12 layers high without a “clean room” or multimillion dollar equipment traditionally required.
Astronomers have discovered the first exception to the dust disk planet formation rule - a 25-million-year-old dust disk that shows no evidence of planet formation.
Working with platinum nanowires 100 times thinner than a human hair a team of U.S. and Japanese researchers has demonstrated a technique that may allow doctors to monitor individual brain cells.
An environmental engineer at Washington University in St. Louis has created a device similar to a hydrogen fuel cell that uses bacteria to treat wastewater and create electricity.
Data from Deep Impact's instruments indicate an immense cloud of fine powdery material was released when the probe slammed into the nucleus of comet Tempel 1 at about 10 kilometers per second.
'The strength and weakness of physicists is that we believe in what we can measure. And if we can't measure it, then we say it probably doesn't exist. And that closes us off to an enormous amount of phenomena that we may not be able to measure because they only happened once. For example, the Big Bang. ... That's one reason why they scoffed at higher dimensions for so many years. Now we realize that there's no alternative... '
