Science is the academic journal of the American Association for the Advancement of Science and is one of the world's top scientific journals. The peer-reviewed journal, first published in 1880, is circulated weekly and has a print subscriber base of around 130,000. Because institutional subscriptions and online access serve a larger audience, its estimated readership is one million people. The major focus of the journal is publishing important original scientific research and research reviews, but Science also publishes science-related news, opinions on science policy and other matters of interest to scientists and others who are concerned with the wide implications of science and technology. Unlike most scientific journals, which focus on a specific field, Science and its rival Nature cover the full range of scientific disciplines. Science's impact factor for 2010 was 31.364 (as measured by the Institute for Scientific Information).
Researchers extend galvanic replacement reactions to metal oxide nanocrystals
(Phys.org) —A large team of researchers, most of which are based in Korea, has succeeded in extending the process of galvanic replacement reactions to ionic compounds. In their paper published in the journal ...
University of Illinois biophysicists measure mechanism that determines fate of living cells
(Phys.org) —New tension gauge tether (TGT) laboratory method developed at the University of Illinois at Urbana-Champaign has broad applications for research into stem cells, cancer, infectious disease, ...
New filtration material could make petroleum refining cheaper, more efficient
A newly synthesized material might provide a dramatically improved method for separating the highest-octane components of gasoline. Measurements at the National Institute of Standards and Technology (NIST) ...
Bittersweet: Bait-averse cockroaches shudder at sugar
Sugar isn't always sweet to German cockroaches, especially to the ones that avoid roach baits. In a study published May 24 in the journal Science, North Carolina State University entomologists show the ne ...
Accurate distance measurement resolves major astronomical mystery
(Phys.org) —Sometimes astronomy is like real estate—what's important is location, location, and location. Astronomers have resolved a major problem in their understanding of a class of stars that undergo ...
A quantum simulator for magnetic materials
Physicists understand perfectly well why a fridge magnet sticks to certain metallic surfaces. But there are more exotic forms of magnetism whose properties remain unclear, despite decades of intense research. ...
Gold nanocrystal vibration captured on billion-frames-per-second film (w/ video)
A billon-frames-per-second film has captured the vibrations of gold nanocrystals in stunning detail for the first time.
Novel features of helium-3 superfluidity discovered with new SQUID detector chip
(Phys.org) —In order to study many complex phenomena, physicists seek to isolate them in potential wells or boxes with easily described forms and boundary conditions. These features in turn dictate various ...
Review finds need for more water quality data in the Marcellus shale region
(Phys.org) —What to do with Marcellus shale wastewater is one of the biggest concerns in Pennsylvania, and few published studies have evaluated such wastewater effects on regional waters, according to a review co-authored ...
Ladybirds, biological weapons and the success of invasive species
Kinks and curves at the nanoscale
One of the basic principles of nanotechnology is that when you make things extremely small—one nanometer is about five atoms wide, 100,000 times smaller than the diameter of a human hair—they are going ...
Researchers use light projector and single-pixel detectors to create 3-D images
(Phys.org) —Researchers from the University of Glasgow and the University of Cambridge have devised a unique method of capturing three-dimensional images. As described in a paper published in the journal Science, they u ...
Ecologists warn of overreliance on unvetted computer source code by researchers
(Phys.org) —A team of scientists, led by ecologist Lucas Joppa of Microsoft Research, has published a commentary piece in the journal Science, highlighting what they say is a growing problem in research efforts. They s ...
Single-pixel power: Scientists make 3-D images without a camera
Their system uses simple, cheap detectors which have just a single pixel to sense light instead of the millions of pixels used in the imaging sensors of digital cameras.
Fracking risks to ground water assessed
(Phys.org) —Extraction of "unconventional" gas from sedimentary rocks such as shale could provide a clean energy source and help some regions to become energy independent, but concerns have been raised ...
