Researchers at the University of California at Berkeley want to make tracking the flow of a body of water as simple as tracking other phenomena, like weather patterns or the flow of traffic. In the pursuit of this goal, they have developed the Floating Sensor Network project, a system comprised of 100 motorized devices that measure temperature, salinity, and other information as they drift along a water surface. The fleet of buoys, which was field tested last week, are equipped with a...

Graphene Rips Follow Rules

[ Watch the Video ] Rice University simulations show carbon sheets tear along energetically favorable lines Research from Rice University and the University of California at Berkeley may give science and industry a new way to manipulate graphene, the wonder material expected to play a role in advanced electronic, mechanical and thermal applications. When graphene — a one-atom thick sheet of carbon — rips under stress, it does so in a unique way that puzzled...

Researchers coax viruses to assemble into synthetics with microstructures and properties akin to those of corneas, teeth and skin Using a simple, single-step process, engineers and scientists at the University of California at Berkeley recently developed a technique to direct benign, filamentous viruses called M13 phages to serve as structural building blocks for materials with a wide range of properties. By controlling the physical environment alone, the researchers caused the viruses...

Frequently captured birds found to be at less risk of injury compared to birds captured once Capturing birds using mist nets to study behavior, movement or the demographics of a species is one of the most common research techniques in ornithology, yet until now there have been no large scale studies into the risks mist nets pose to birds. Writing in the British Ecological Society's Methods in Ecology and Evolution researchers from California used a dataset of over 345,000 records to evaluate...

US astronomers said Friday that they are now listening to the skies for the existence of ETs, using a massive radio telescope in West Virginia to scan for signs of alien life on 86 possible Earth-like planets in the heavens above.The giant dish began pointing toward each of the planets this week and will gather 24 hours of data on each one. The 86 planets were gleaned from a list of 1,235 planets identified by NASA's Kepler space telescope."It's not absolutely certain that all of these stars...

Steep decline of many animal species warns that Earth is on the brink With the steep decline in populations of many animal species, scientists have warned that Earth is on the brink of a mass extinction like those that have occurred just five times during the past 540 million years. Each of these "Big Five" saw three-quarters or more of all animal species go extinct. In results of a study published in this week's issue of journal Nature, researchers report on an assessment of where mammals...

Physicists working at the European Organization for Nuclear Research (CERN) announced on Wednesday that they had successfully trapped and stored antimatter atoms for the first time ever. Scientists from the Geneva, Switzerland-based research organization, in association with the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley, trapped a substance known as antihydrogen--the antimatter equivalent of hydrogen. The international...

Inhibiting certain brain cells sharpens animal's response to small and quick visual stimuli Between alerting us to danger and allowing us to spot prey, vision keeps many animals, including humans, alive. But exactly how does this important sense work, and why is it easier for us to spot movement of small objects in our field of vision, than to notice other things? The complexity of the neural network that supports vision has long baffled scientists. Now, with a new technology and support from...

Vegetation and sand found to be essential in stream life In a feat of reverse-engineering, Christian Braudrick of University of California at Berkeley and three coauthors have successfully built and maintained a scale model of a living meandering gravel-bed river in the lab. Their findings point to the importance of vegetation to reinforce the banks and, surprisingly, to the importance of sand in healthy meandering river life. The significance of vegetation for slowing erosion and reinforcing...

Metallic glass that's stronger and lasts longer The normal structure of metals is crystalline. Glass, on the other hand, is amorphous. But it's possible to make amorphous forms of metal, metallic glasses, which can be remarkably strong, having many properties equal to or better than their crystalline metal cousins. The catch is that bulk metallic glasses are highly susceptible to fatigue, a severe problem for their use as structural materials. Now researchers at the U.S. Department of...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
