Not so long ago our computers had a single core which had to be boosted for performance - making each machine into a great central heating system. Beyond 85° C, however, electronic components become unstable. To overcome this physical limit, a solution was found with the multicore technology, where the same chip includes several processors which share tasks. Most of today's consumer electronics proudly boast a "dual core" or "quad core". However, in time the technology will come up against the same physical limits. http://www.physorg.com/news179755670.html Technology Fri, 11 Dec 2009 12:10:05 EST news179755670 (PhysOrg.com) -- "For years, we have been using laser cooling to trap and manipulate atoms," David DeMille tells PhysOrg.com. "This has been very useful for both basic science and many applications. Recently there has been great interest in cooling and trapping molecules as well. Their rich internal structure makes molecules useful for a wide range of new experiments and possible applications." http://www.physorg.com/news179397985.html Physics Mon, 07 Dec 2009 08:47:03 EST news179397985 (PhysOrg.com) -- "Scientists have been working with dipole fields for quite some time," Peter Barker tells PhysOrg.com. "However, most of the work is focused on very small particles, like atoms, or on larger particles, such as for use as optical tweezers. There is an interim region between atoms and large particles, and that is what we are looking at. We want to be able to control molecules a little differently." http://www.physorg.com/news176032268.html Physics Thu, 29 Oct 2009 10:52:22 EST news176032268 Should a city that's committed to environmentally friendly construction pay $825,000 for a job that was expected to cost $248,000? http://www.physorg.com/news173379336.html Space & Earth Mon, 28 Sep 2009 22:00:01 EST news173379336 Understanding precisely how fluid boils in tiny "microchannels" has led to formulas and models that will help engineers design systems to cool high-power electronics in electric and hybrid cars, aircraft, computers and other devices. http://www.physorg.com/news172839974.html Technology Tue, 22 Sep 2009 12:07:55 EST news172839974 Scientists have found the "Rosetta Stone" of supervolcanoes, those giant pockmarks in the Earth's surface produced by rare and massive explosive eruptions that rank among nature's most violent events. The eruptions produce devastation on a regional scale -- and possibly trigger climatic and environmental effects at a global scale. http://www.physorg.com/news172766088.html Space & Earth Mon, 21 Sep 2009 15:36:23 EST news172766088 (PhysOrg.com) -- "Scientists have been making Bose-Einstein Condensates [BECs] for nearly 15 years," Charlie Doret tells PhysOrg.com. "Essentially all BEC research to date, however, begins with laser cooling. Unfortunately, laser cooling is impractical for some atoms, and it is especially difficult with molecules, limiting the scope of new research." http://www.physorg.com/news172400869.html Physics Thu, 17 Sep 2009 10:40:11 EST news172400869 You imagine a clock to be different -- yet the optical table with its many complicated set-ups really is one. Optical clocks like the strontium clock in the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig could be the atomic clocks of the future; some of them though are already ten times more precise and stable than the best primary caesium atomic clocks. http://www.physorg.com/news171195370.html Physics Thu, 03 Sep 2009 11:16:41 EST news171195370 (PhysOrg.com) -- An astrophysics experiment in America has demonstrated how fundamental research in one subject area can have a profound effect on work in another as the instruments used for the Laser Interferometer Gravitational-Wave Observatory (LIGO) pave the way for quantum experiments on a macroscopic scale. http://www.physorg.com/news166941860.html Physics Thu, 16 Jul 2009 05:45:09 EST news166941860 On the heels of his discovery in Montana of the first trace fossil of a dinosaur burrow, Emory University paleontologist Anthony Martin has found evidence of more dinosaur burrows - this time on the other side of the world, in Victoria, Australia. The find, to be published this month in Cretaceous Research, suggests that burrowing behaviors were shared by dinosaurs of different species, in different hemispheres, and spanned millions of years during the Cretaceous Period, when some dinosaurs lived in polar environments. http://www.physorg.com/news166471265.html Other Sciences Fri, 10 Jul 2009 19:20:01 EST news166471265 An international team of researchers has studied the coralline algae fossils that lived on the last coral reefs of the Mediterranean Sea between 7.24 and 5.3 million years ago. Mediterranean algae and coral reefs began to resemble present day reefs following the isolation of the Mediterranean from the Indian Ocean and global cooling 15 and 20 million years ago respectively. http://www.physorg.com/news166181578.html Other Sciences Tue, 07 Jul 2009 10:36:55 EST news166181578 In an effort to achieve energy-aware computing, the Swiss Federal Institute of Technology Zurich (ETH), and IBM today announced plans to build a first-of-a-kind water-cooled supercomputer that will directly repurpose excess heat for the university buildings. The innovative system, dubbed Aquasar, is expected to decrease the carbon footprint of the system by up to 85% and estimated to save up to 30 tons of CO2 per year, compared to a similar system using today`s cooling technologies. http://www.physorg.com/news164996567.html Electronics Tue, 23 Jun 2009 17:23:27 EST news164996567 Particles cool down the climate, but to which extent?

A new article in Science by Gunnar Myhre at CICERO, Norway, brings the scientific community a step closer to solving the mystery. http://www.physorg.com/news164613355.html Space & Earth Fri, 19 Jun 2009 07:10:01 EST news164613355 Millions of years ago, rivers ran in Antarctica through craggy mountain valleys that were strangely similar to the European Alps of today, Chinese and British scientists reported on Wednesday. http://www.physorg.com/news163254239.html Space & Earth Wed, 03 Jun 2009 13:24:29 EST news163254239 Approximately a third of the electricity consumed by large data centers doesn't power the computer servers that conduct online transactions, serve Web pages or store information. Instead, that electricity must be used for cooling the servers, a demand that continues to increase as computer processing power grows. http://www.physorg.com/news163176927.html Technology Tue, 02 Jun 2009 15:56:09 EST news163176927 Thomas Brunschwiler, Urs Kloter, Ryan Linderman, Bruno Michel from the IBM's Zurich Research Lab in Switzerland and Hilton Toy from the IBM Server & Technology Group in Fishkill, New York, have been honored with the 2008 Harvey Rosten Award of Excellence for their work in overcoming a barrier in chip cooling by improving the application of a paste that binds chips to their cooling systems. The new technology will allow for faster computer chips to be cooled more efficiently.

The findings suggest that after a sudden rise in species numbers, diatoms abruptly declined about 33 million years ago -- trends that coincided with severe global cooling. http://www.physorg.com/news150642726.html Biology Thu, 08 Jan 2009 13:12:06 EST news150642726 (PhysOrg.com) -- The cooling of electronic components is playing an increasing role in the design process of electronic equipment such as mobile telephones, games computers and laptops. Wessel Wits, PhD student at the University of Twente, has developed two innovative concepts for cooling such devices. Patents for both concepts are pending. Wits will be awarded his doctorate on 4 December at the faculty of Engineering Technology. http://www.physorg.com/news147624858.html Technology Thu, 04 Dec 2008 14:54:18 EST news147624858 (PhysOrg.com) -- AMD has been showing off their soon to be released 45nm "Deneb" desktop chips which have been overclocked to 6.3Ghz.
