Revolutionary technology to improve bedside tumor diagnosis in patients

Science Daily - Mon, 01/06/2015 - 12:24pm
A mini hybrid gamma ray camera has been developed and is expected to revolutionize identification and removal of tumors and lymph nodes. A ‘hybrid technology’ mini camera combines optical and gamma imaging to improve diagnosis and lymph and tumour removal efficiency. The small size of camera allows for bedside diagnosis as well as for small organ imaging, surgical investigation and visualisation of drug delivery. Researchers are also investigating other clinical applications for the technology including thyroid, lymphatic drainage and ‘lacrimal drainage’

Better welding with speedy laser mirrors

Science Daily - Mon, 01/06/2015 - 12:24pm
Silicon micromirrors can guide laser beams at extremely high speeds, allowing operators to dose heat input to workpieces with absolute precision. But to date they have not been robust enough to be used for laser cutting and welding. Now a Fraunhofer team has managed to develop fast, durable mirrors that are capable of performing challenging cutting and welding tasks.

Lasers are key to mastering challenges in lightweight construction

Science Daily - Mon, 01/06/2015 - 12:24pm
Many joining and cutting processes are possible only with lasers. New technologies make it possible to manufacture metal components with hollow structures that are significantly lighter and yet just as stable as solid components. In addition, lasers can be used to combine various lightweight construction materials and steels with each other.

Khan Academy Seeks Patents On Learning Computer Programming, Social Programming

Slashdot - Mon, 01/06/2015 - 12:21pm
theodp writes: When it announced its brand new Computer Science platform in August 2012, Khan Academy explained it drew inspiration from both Bret Victor and GitHub (SlideShare). Still, that didn't stop Khan Academy from eventually seeking patents on its apparently Victor-inspired Methods and Systems for Learning Computer Programming and GitHub-inspired Systems and Methods for Social Programming, applications for which were quietly disclosed by the USPTO earlier this year. Silicon Valley legal powerhouse Wilson Sonsini Goodrich & Rosati, which provides a pro bono team of 20+ to assist billionaire-backed Khan Academy with its legal needs, filed provisional patent applications for KA in August 2013 — provisional applications can be filed up to 12 months following an inventor's public disclosure of the invention — giving it another 12 months before formal claims had to be filed (KA's non-provisional applications were filed in August 2014).

A new site on the World Heritage List?

Science Daily - Mon, 01/06/2015 - 11:58am
Near the border with Botswana in the Shashi-Limpopo region lies Mapela, which is now an excavation site. The ruins of what is believed to have been a flourishing urban community for an astoundingly long period of time were first examined in the early 1960s. As a result of political developments in the country, which at that time was known as Rhodesia, the site was later abandoned and forgotten by the archaeologists.

Contaminant particles increase hospital admissions for children with respiratory illnesses

Science Daily - Mon, 01/06/2015 - 11:58am
Particles of less than 2.5 microns emitted by vehicles have negative repercussions for bronchiolitis, pneumonia, asthma and bronchitis in children. Should their concentrations be reduced to the levels recommended by the WHO, hospital admissions of children with these illnesses would decrease, amounting to a daily saving of 200 euros, according to calculations by medical researchers.

Psychology: Does aging affect decision making?

Science Daily - Mon, 01/06/2015 - 11:58am
Aging is associated with significant decline in cognitive functions. But does this translate into poorer decision making? Psychologists report that in simple decision situations, older adults perform just as well as younger adults. However, according to their study, aging may affect decision performance in more complex decision situations.

People more likely to cheat as they become more economically dependent on their spouses

Science Daily - Mon, 01/06/2015 - 11:56am
Both men and women are more likely to cheat on their spouses the more economically dependent they are on them, according to a new study. The work concludes that economic dependency increases the likelihood of engaging in infidelity for both men and women, and that in particular, there appears to be something that makes men who are not primary breadwinners even more prone to cheating compared to women who are not primary breadwinners.

Tor Connections To Hidden Services Could Be Easy To De-Anonymize

Slashdot - Mon, 01/06/2015 - 11:33am
angry tapir writes with news of a report presented Friday at Hack In The Box which outlines a counterintuitive fact about Tor: Identifying users who access Tor hidden services — websites that are only accessible inside the Tor anonymity network — is easier than de-anonymizing users who use Tor to access regular Internet websites. That's because the addresses of the Hidden Service Directories (HSDirs) used to index those Tor-network-only sites, though shuffled daily, can be predicted (and hijacked) with cheap brute-force techniques. "The researchers managed to place their own nodes as the 6 HSDirs for facebookcorewwwi.onion, Facebook's official site on the Tor network, for the whole day on Thursday. They still held 4 of the 6 spots on Friday. Brute-forcing the key for each node took only 15 minutes on a MacBook Pro and running the Tor relays themselves cost US$62 on Amazon's EC2 service.
