Nanotechnology Used to Hunt for Hidden Pathogens

Isolation of MAP requires collection of infected white bloods cells from blood samples via centrifugation. For direct nPCR analysis, DNA directly isolated from white blood cells is purified in multiple steps prior to amplification and detection by gel electrophoresis. Meanwhile, culture-based nPCR requires the growth of MAP in specialized liquid media for 12 weeks, followed by DNA isolation before nPCR. Hybridizing magnetic relaxation sensors (hMRS) can detect MAP DNA in minimally processed blood samples via changes in magnetic signal (”¤2) in 1 hour, as opposed to 24 hours for direct nPCR and 12 weeks for culture nPCR.

Researchers at the University of Central Florida have developed a novel technique that may give doctors a faster and more sensitive tool to detect pathogens associated with inflammatory bowel disease, including Crohn’s disease.

The new nanoparticle-based technique also may be used for detection of other microbes that have challenged scientists for centuries because they hide deep in human tissue and are able to reprogram cells to successfully evade the immune system…

Prius and Volt Set New Sales Records Thanks to High Gas Prices

Gas prices are a supreme motivator.

Drivers tend to convert to the fuel-efficiency religion once they get severely wounded in the wallet. It’s a sad fact that environmental concerns alone are often not enough… Of course, the best ways to save on gas costs are to walk, bike, and take transit (for an example of a city that has great sustainable transportation, check out Colombia’s Medellin). But if you’re going to drive, you should get the most fuel-efficient vehicle that meets your needs. Near the top of the list, the Chevrolet Volt and Toyota Prius can be found, and thanks to relatively high gas prices in the U.S. lately, they’ve both set new sales records in March 2012.

Teens in the U.S. are waiting longer to drive

Teens are not rushing to get a driver’s license.

Getting a drivers license has been as much a rite of passage as the high school prom, but a new study suggests that young Americans are no longer rushing to get a driver’s license the moment they are eligible – and the Internet may be a major reason for that delay.

30% of all internet traffic is pornography

Biggest porn site on the internet gets over four billion hits a month.

‘The internet is for porn,’ is the title of a song on hit musical Avenue Q.  And it turns out the lyricists had touched on a home truth, because researchers have discovered that a staggering 30 per cent of all internet traffic is pornography.

Kids born to obese moms are more likely to diagnosed with autism.

Kids born to obese women are more likely to be diagnosed with autism or related developmental delays than the children of slimmer moms according to a new study of moms and children in California.

Limits to growth: 40 year old prediction of ‘collapse’ still on track

Futurism-Got-Corn-graph

In a controversial study released 40 years ago, recent research supports the conclusions of that study: The world is on track for disaster. So says Australian physicist Graham Turner, who revisited perhaps the most groundbreaking academic work of the 1970s,The Limits to Growth.

2012 Hugo Award nominees announced

hugo-awards 63363

Last night saw the announcement of the 2012 nominees for science fiction’s prestigious Hugo Award. It’s a particularly fine ballot, reflecting a record number of nominating ballots (wisdom of the crowds and all that). Included on the ballot are our own moderator Avram (as part of the team that publishes The New York Review of Science Fiction) and one of my all-time favorite books, Among Others. Also noteworthy: the much-deserved John W Campbell Award nomination (for best new writer) for the fabulous Mur Lafferty, a nomination for the indispensable Science Fiction Encyclopedia, Third Edition, a nomination for IO9’s Charlie Jane Anders’s story Six Months, Three Days, and a fourth nomination for much-favored Fables graphic novels…
