Thrombosis – the formation of internal blood clots – is a common cause of complications and even death following surgery. To create a better means of preventing thrombosis, researchers at University of Pennsylvania School of Medicine coated red blood cells (RBCs) with tissue plasminogen activator (tPA), a clot-dissolving drug commonly used as an emergency treatment for stroke. When given alone, tPA has a short life span in circulation and has the potential to cause serious bleeding as it diffuses out

A European team of scientists from the University of Dundee (UK), the Technical University of Munich (Germany) and the European Synchrotron Radiation Facility, ESRF, (France) have determined the structure of a key target enzyme for novel drug development to treat infectious diseases including malaria, tuberculosis and sexually transmitted bacterial infections. The results of their collaboration are published on the August 5 issue of Proceedings of the National Academy of Sciences.

It will never be the same old song again–this was the concept for MS3, a Hungarian musician when he created a software solution he calls „digital improvisation” or DI. The „di” music file format he developed enables the users to listen to one song in endless number of versions. „Imagine Madonna’s new releases were recorded in di format. Whenever you hit the ’’Play’’ button, a different remix of the same song is played back. You never get bored of your cd then” said Mester, now hea

Simulate Network Traffic from over 1 Million Web Browsers in Near Real Time

Researchers at the Georgia Institute of Technology have created the fastest detailed computer simulations of computer networks ever constructed—simulating networks containing more than 5 million network elements. This work will lead to improved speed, reliability and security of future networks such as the Internet, according to Professor Richard Fujimoto, lead principal investigator of the DARPA-funded projec

Moore´s Law – a dictum of the electronics industry that says the number of transistors that fit on a computer chip will double every 18 months – may soon face some fundamental roadblocks. Most researchers think there´ll eventually be a limit to how many transistors they can cram on a chip. But even if Moore´s Law could continue to spawn ever-tinier chips, small electronic devices are plagued by a big problem: energy loss, or dissipation, as signals pass from one transistor to the next. Line up all t

New use for seismic reflection data: revealing the most dangerous fault lines on Earth

Researchers have found an important new application for seismic reflection data, commonly used to image geological structures and explore for oil and gas. Recently published in the journal Nature, new use of reflection data may prove crucial to understanding the potential for mega earthquakes.
