  • Research challenges Heisenberg's uncertainty principle
    Scientists have successfully found a means to directly measure the polarization of light, a discovery that researchers say flies in the face of Heisenberg's uncertainty principle, according to findings published in the journal Nature Photonics. Researchers previously could only indirectly measure the wavefunction, but the discovery could alter the way scientists approach quantum mechanics in the future.

  • Superconductive material can work at high temperatures
    A multilayer superconductor capable of carrying large electric currents in high temperatures is bringing scientists one step closer to developing practical superconductors for medical and technological use. Most superconductors can only operate at extremely cold temperatures, making real-world use impossible; however, the material being developed by a group of scientists led by a University of Wisconsin-Madison professor could change that.

  • NASA pauses Mars rover operations over technical difficulties
    NASA officials temporarily suspended the Mars Curiosity operation last week after a computer glitch occurred during the rover's attempt to analyze its first sample of rock powder. Engineers say the issue is in the flash memory system and speculate that it could be related to radiation. Limited operations mayx be resumed this week.

  • Scientists find neighboring star has similar layers to the sun
    Researchers have discovered that a nearby star, Alpha Centauri A, has a cool layer in its atmosphere, similar to that of our sun, whose cooler layer dips to a balmy 7,300 degrees Fahrenheit from its usual 10,000 degrees. Scientists made the discovery using an infrared space telescope at the Herschel space observatory. "Detailed observations of this kind for a variety of stars might help us decipher the origin of such layers and the overall atmospheric heating puzzle," said René Liseau, leader of the study.

  • Space photos from Saturn captures Venus in its vantage point
    NASA's Cassini spacecraft has captured two photographs of Venus from its viewpoint orbiting Saturn. In the photos, Venus appears as a bright white dot. The $3.2 billion Cassini -- a joint mission between NASA, the European Space Agency and the Italian Space Agency -- has been orbiting Saturn since 2004. (3/4) LinkedInFacebookTwitterEmail this Story
  • Material could keep windshields free of fog and frost
    Scientists are working to develop a fog- and frost-repelling material using hydrophilic and hydrophobic components. Researchers have found that a combination can prevent frost and fog from forming on windshields. Large quantities of water, however, can still limit the material. "You wouldn't want this on an airplane wing that constantly gets water on it, but an application like eyeglasses or windshields, it can be amazing," said researcher Michael Rubner.

  • Ancient croc skulls provide link between North, South America
    Ancient reptilian skulls discovered in the Panama Canal belong to a group of crocodilians believed to have lived about 20 million years ago during the Miocene era, according to findings published in the Journal of Vertebrate Paleontology. Researchers say reptiles that lived in North and South America could be connected by an ancient seaway that may have carried them south. "The tropics hold some of the greatest diversity on the planet. Yet there's still so little that we know about them," said Jonathan Bloch, co-author of the study. He added that the Panama discovery is "a new window back into the past that's very difficult to get at in the tropics." (3/4) LinkedInFacebookTwitterEmail this Story

  • Report: Small-scale mining provides jobs, but comes with great risks
    While small-scale mining can provide a sustainable livelihood for millions of lower-class people, the lack of oversight and interest from developmental agencies leaves too much room for the industry to operate illegally and inefficiently, according to a report by the International Institute for Environment and Development. The report suggests stronger policies to address the knowledge and safety gaps. "IIED is planning a new knowledge and network program that will try and address the gaps and ultimately deliver better and more effective policies," said IIED official Sarah Best.
