(PhysOrg.com) -- European researchers working on some of the most fundamental issues facing the future internet paradigm have developed - in their spare time, no less - a mobile platform that brings some of the most powerful and compelling Web 2.0 services to the real, mobile world. `Engineers like to play with toys too,` says Daniele Miorandi, coordinator of the BIONETS project, explaining why their team developed its U-Hopper platform, an `opportunistic` communication platform for mobile phones. http://www.physorg.com/news156098957.html Technology Thu, 12 Mar 2009 17:52:43 EST news156098957 In the life of many successful networks, the connections between elements increase over time. As connections are added, there comes a critical moment when the network's overall connectivity rises rapidly with each new link. http://www.physorg.com/news156087603.html Other Sciences Thu, 12 Mar 2009 14:40:26 EST news156087603 (PhysOrg.com) -- Handsets, laptops, cars and even clothes: they are all part of the ‘network of things`, an incarnation of the future internet, and European researchers are working hard to create that future now. http://www.physorg.com/news155834634.html Technology Mon, 09 Mar 2009 16:24:36 EST news155834634 The possibility of remote monitoring for chronically ill patients will soon become a reality. Now, researchers in South Africa and Australia have devised a decentralized system to avoid medical data overload. They describe the peer-to-peer system in a forthcoming issue of the International Journal of Computer Applications in Technology. http://www.physorg.com/news155810080.html Technology Mon, 09 Mar 2009 09:35:15 EST news155810080 (PhysOrg.com) -- A new approach to wireless communication will guarantee the reachability of emergency services in a better way. 'Cognitive radio', for which Qiwei Zhang (CTIT) developed new techniques, borrows free space in other frequency bands or even organizes an ad hoc network 'on the spot'. http://www.physorg.com/news155234869.html Technology Mon, 02 Mar 2009 16:48:22 EST news155234869 A team of researchers from Princeton University and the Drexel University College of Medicine has found that the parasite that causes malaria breaks down an important amino acid in its quest to adapt and thrive within the human body. By depleting this substance called arginine, the parasite may trigger a more critical and deadlier phase of the disease. http://www.physorg.com/news154265671.html Biology Thu, 19 Feb 2009 11:35:25 EST news154265671 "Conventional wisdom - and conventional theory - tells us that when infection can potentially be spread to almost everyone in a community, such as for measles, a disease outbreak can never be contained using voluntary vaccination," says Chris Bauch and Ana Persic, researchers from the University of Guelph. "However, our work shows conventional wisdom may be wrong for diseases that are spread primarily through close contact, such as smallpox." Their findings appear in the open-access journal PLoS Computational Biology on February 6th. http://www.physorg.com/news153145959.html Biology Fri, 06 Feb 2009 12:33:05 EST news153145959 A quartet of studies by researchers at the California Institute of Technology (Caltech) highlight a special feature on gene regulatory networks recently published in the Proceedings of the National Academy of Sciences (PNAS). http://www.physorg.com/news152979184.html Biology Wed, 04 Feb 2009 14:13:44 EST news152979184 A quartet of studies by researchers at the California Institute of Technology (Caltech) highlight a special feature on gene regulatory networks recently published in the Proceedings of the National Academy of Sciences (PNAS). http://www.physorg.com/news152893662.html Biology Tue, 03 Feb 2009 14:29:53 EST news152893662 Nothing kills innovation like having to reinvent the wheel. Imagine how dull your diet would be if you had to build a new stove and hammer out a few cooking pots every time you wanted to test a new recipe. Until just a couple of years ago, electronics researchers testing new high-speed wireless technologies faced just this sort of problem; they had to build every test system completely from scratch. http://www.physorg.com/news152470346.html Technology Thu, 29 Jan 2009 16:52:47 EST news152470346 Since early January, a worm that has been referred to by several names, including "Downadup," "Kido" and "Conficker," has been infecting millions of computers around the world. The worm exploits a previously discovered vulnerability in Microsoft's Windows operating system to steal network passwords from the computer systems of large companies, educational and public institutions. http://www.physorg.com/news152383229.html Technology Wed, 28 Jan 2009 16:41:30 EST news152383229 A team of computer scientists at the University of Pennsylvania investigating the political, social and economic struggle between individual self-interest and the need to build a consensus have learned that, depending only on the structure of the network of participants, they can engineer surprising experimental results. http://www.physorg.com/news152373886.html Technology Wed, 28 Jan 2009 14:05:22 EST news152373886 Scientists have already hooked brains directly to computers by means of metal electrodes, in the hope of both measuring what goes on inside the brain and eventually healing conditions such as blindness or epilepsy. In the future, the interface between brain and artificial system might be based on nerve cells grown for that purpose. In research that was recently featured on the cover of Nature Physics, Prof. Elisha Moses of the Physics of Complex Systems Department and his former research students Drs. Ofer Feinerman and Assaf Rotem have taken the first step in this direction by creating circuits and logic gates made of live nerves grown in the lab. http://www.physorg.com/news152364147.html Physics Wed, 28 Jan 2009 11:22:49 EST news152364147 Transportation and security officials on Inauguration Day will have a centralized, consolidated stream of traffic information and other data displayed on a single screen using software developed by the University of Maryland.

Or are they? A Northwestern University study has found a surprising similarity among four quite different organisms. The simplest organism, a bacterium called H. pylori, uses the same number of biochemical reactions (around 300) as yeast, the largest, most complex organism of the group, when optimizing growth. http://www.physorg.com/news147696605.html Biology Fri, 05 Dec 2008 10:50:05 EST news147696605 Internet network performance problems are not only annoying to users -- they are costly to businesses and network operators.

They are studying the process of evolution not through fossils but directly, as it is happening. Now, by modeling the steps evolution takes to build, from scratch, an adaptive biochemical network, biophysicists Eric D. Siggia and Paul Francois at Rockefeller University have gone one step further. Instead of watching evolution in action, they show that they can predict its next best move. http://www.physorg.com/news144604965.html Biology Thu, 30 Oct 2008 17:02:45 EST news144604965 (PhysOrg.com) -- European researchers are developing the world`s first optical firewall capable of analysing data on fibre optic networks at speeds of 40 gigabits per second.
