+ - Cellular details of coronary artery with microOCT ->

Submitted by RogerRoast
RogerRoast (1914292) writes "Using a high-resolution imaging technology, researchers at MGH were able to show individual arterial and inflammatory cells, including features that may identify vulnerable plaques, within coronary artery samples. The development of this new technology was reported in the latest online issue of Nature Medicne. The intravasular imaging technology is called micro optical coherence tomography or micro OCT. As described in a science news story, according to the lead author, "the ability to track and follow cells in three dimensions could help us prove or disprove many theories about coronary artery disease and better understand how clots form on a microscopic level.""

Submitted by
BogenDorpher
BogenDorpher writes "In a recent study by the Governors Highway Safety Association, driving distractions such as cell phones and other electronic devices, cause as much as 25% of all US car accidents. It is common knowledge that driving while distracted is not a safe thing to do, but now we have some scientific data that goes in-depth on the topic."

coondoggie writes "you could fly to the edge of our universe you'd find giant magnetic bubbles about 100 million miles wide.

That's what computer models digesting data from NASA's Voyager spacecraft, which are now close to 10 billion miles away from Earth, are suggesting as they try to figure out the information being beamed from the edge of our solar system."

+ - Reducing Software Patent Life-spans

Submitted by seattle_coder
seattle_coder (708761) writes "Many have advocated for the elimination of software patents. The arguments generally are that software patents are handed out to easily, and that they're too difficult and expensive to fight. Some say that patents just plain don't make sense for software, which is such a dynamic technology. Given that the standard patent lifetime is 20 years, and software changes so rapidly, is the life-span the problem for software patents? Would reducing the software patent lifetime to 5 years or even less be the thing to do?"
Programming

+ - Protothreads vs State Machines->

Submitted by Anonymous Coward
An anonymous reader writes "State machines are a well-known way to write event-driven code, such as device drivers and other low-level code. Although state machines are efficient, they may lead to code that is difficult to follow because code cannot "block": every function must always return immediately. Protothreads, a widely used programming technique invented by Swedish computer scientist Adam Dunkels, allow event-driven programs to block, making it possible to use traditional programming flow control statement such as if-then-else and while loops. Miro Samek, author of the book Practical UML Statecharts in C and C++, argues that protothreads typically do not lead to cleaner code but that state machines are both more powerful and cleaner. What do Slashdot readers think: state machines or protothreads?"

splitenz (762865) writes "Look, it's just the Internet, people. We don't need a new word to say that data is stored on a central server. Jason Cross can't wait for the day when "cloud" joins the dustbin of overused and meaningless technology marketing words, along with push, virtual reality, and multimedia. And he has plenty of good reasons why."

+ - Researchers Develop Super Batteries From Aerogel-> 1

Submitted by
greenerd
greenerd writes "Researchers from the University of Central Florida may have found the most efficient (and most bizarre) battery material yet – ‘frozen smoke’, also known as Aerogel. One of the world’s lightest solids, aerogel contains multi-walled carbon nanotubes (MWCNT) which each one several thousands thinner than human hair. The researchers, Associate Professor Lei Zhai and Postdoctoral Associate Jianhua Zou, believe that this material could soon become the best energy storage material for capacitors and batteries."

+ - Torture testing USB drives->

Submitted by Anonymous Coward
An anonymous reader writes "You drop them on the floor, loose them in the wash, and if you're really lax let them get run over. But just how durable are USB drives, and do the ones that claim to be 'rugged' really live up to it? Australian consumer organisation CHOICE decided to find out, and torture tested 18 popular USB drives putting them through wash cycles, oven tests and, yes, even running them over with a car (see video). The results were surprising, with some normal USB keys turning out to be more durable than the supposed 'rugged' variety! See the story (http://www.choice.com.au/reviews-and-tests/technology/computers-and-accessories/storage/usb-flashdrive-review-and-compare.aspx) to find out which ones survived."

mudimba (254750) writes "Microsoft has made grand announcements about how great their implementation of the HTML5 canvas specification is. However, while I was porting a large HTML5 application to work with IE9 beta I found that there are some key features missing. Workarounds are provided where possible.
