(Phys.org) -- It may be a wet summer, but seagulls are benefiting from climate change.
(Phys.org) -- Selfish behaviour is a threat to successful coexistence and mutual cooperation. In many cases this human cooperation is based on punishing those who do not cooperate. There can be two different forms of punishment here: direct punishment by peers and institutionalised punishment by institutions like the police. Arne Traulsen, Torsten Röhl and Manfred Milinski from the Max Planck...
(Phys.org) -- It was a little over two years ago that the Large Hadron Collider kicked off its search for the Higgs boson. But the hunt for the Higgs really began decades ago with the realization of a puzzle to be solved, one that involved more than just the Higgs.
How can an electrically conductive interface appear at the junction between two materials which do not conduct electricity? Since such a phenomenon was discovered in 2004, conflicting hypotheses have been put forward in order to respond to this question, each with its fervent supporters and critics. An international team bringing together researchers from the Paul Scherrer Institute (PSI), the...
(Phys.org) -- A team of astronomers have used the United Kingdom Infrared Telescope (UKIRT) on Hawaii to discover four pairs of stars that orbit each other in less than 4 hours. Until now it was thought that such close-in binary stars could not exist. The new discoveries come from the telescope's Wide Field Camera (WFCAM) Transit Survey, and appear in the journal Monthly Notices of the Royal...
Researchers have developed a method to determine the location of a spacecraft within one hundred metres, even if the spacecraft is several hundred million kilometres from Earth. In addition to spacecraft-spotting, the same technique can be applied to study the atmosphere of our neighbouring planets or the structure of the planets interior using radio telescopes. Thus, for example,...
This image shows four separate images of the M5.3 class flare from the morning of July 4, 2012. In clockwise order starting at the top left, the wavelengths shown are: 131, 94, 193, and 171 Angstroms. Each wavelength shows a different temperature of material, which in turn corresponds to different levels of the sun's atmosphere. By looking at images in several wavelengths, scientists can track how...
Physicists said Thursday the potential discovery of the "God particle" was a gateway to a new era that could see humanity unlock some of the universe's great mysteries including dark matter.
Apple is preparing to launch a smaller tablet computer in the coming months in a bid to maintain its edge in an increasingly crowded market, the Wall Street Journal reported Thursday.
Taiwan's leading smartphone maker HTC Thursday hailed as a victory a British court ruling that it did not infringe on a patent owned by the US technology giant Apple.
Seabirds feed their young less as they reach an age to fly the nest, but it's hormones that actually control when the chicks leave home, according to new research from the University of Leeds.
A Japanese parliament probe into the nuclear disaster at Fukushima is expected to say the then prime minister fanned chaos in the opening days of the crisis when it publishes its final report Thursday.
(Phys.org) -- A Microsoft engineer has spotted a botnet that targets Yahoo! Mail users using Android devices. Terry Zink , who also writes an Internet security blog, said he has evidence of a botnet running on Android devices where spam e-mail messages are being sent from Yahoo mail servers on Android devices, logging into Yahoo! mail accounts and sending off spam. Zink, embarking on a tracking...
One bit of digital information stored on a hard disk currently consists of about 3 million magnetic atoms. Researchers from Germany and Japan have now developed a magnetic memory with one bit per molecule. By an electric pulse, the metal-organic molecule can be switched reliably between a conductive, magnetic state and a low-conductive, non-magnetic state. This novel correlation for molecules is...
WEDNESDAY 4. JULY 2012
Scientists working at the world's biggest atom smasher near Geneva have announced the discovery of a new subatomic particle that looks remarkably like the long-sought Higgs boson. Sometimes called the "God particle" because its existence is fundamental to the creation of the universe, the hunt for the Higgs involved thousands of scientists from all over the world.
(AP) The European Union says it has launched a new smartphone application which allows air and rail passengers stranded in the EU due to cancellations or delays to immediately check on their legal rights regarding rebates and compensation.
Melting glaciers and ice sheets have contributed more to rising sea levels in the past decade than expansion from warming water, according to modelling in the latest report by the Antarctic Climate and Ecosystems (ACE) Cooperative Research Centre.
A study published in the July 5 edition of the journal Nature is challenging scientists' understanding of planet formation, suggesting that planets might form much faster than previously thought or, alternatively, that stars harboring planets could be far more numerous.
Searching and finding in audio archives can be improved if we take a different look at the underlying technology and allow for how the results are used. This provides a better picture of the problems and the points for improvement. Laurens van der Werff demonstrated this in his PhD thesis 'Evaluation of Noisy Transcripts for Spoken Document Retrieval', which he will defend on 5 July at the...
Summer is a good time to relax, sleep late, enjoy a break from school or work. Waking before sunrise is just not done.
(Phys.org) -- Psychologists from Royal Holloway, University of London believe a collaborative writing project can help boost self-esteem and improve core skills such as team work among young people.
Dissemination of public documents was slow and labor-intensive in 1776. Its too late to know for sure, but its interesting to speculate why a colonial printer hurried, perhaps carried away by the excitement would print copies of the Declaration of Independence and get the date wrong: June, weeks before the document was actually signed.
On June 28 NASAs Cassini spacecraft passed by Tethys, a 1,062-kilometer (662-mile) -wide moon of Saturn thats made almost entirely of ice. Tethys is covered in craters of all sizes but by far the most dramatic of all is the enormous Odysseus crater, which spans an impressive 450 kilometers (280 miles) of the moons northern hemisphere nearly two-fifths of its entire...
Hydrogen gas (H2) is an ideal energy carrier for fuel cells, but finding sustainable ways to produce large quantities of hydrogen continues to be a technological challenge. Jia Zhang at the A*STAR Institute of High Performance Computing and co-workers have now used sophisticated calculations to uncover a critical chemical mechanism that may make catalytic transformation of safe, renewable liquid...
