Lab-on-a-Chip breakthrough aims to help physicians detect cancer and diseases at the nanoscale

Posted by in categories: biotech/medical, computing, nanotechnology, particle physics

Nice!


IBM scientists have developed a new lab-on-a-chip technology that can, for the first time, separate biological particles at the nanoscale and could help enable physicians to detect diseases such as cancer before symptoms appear.

As reported today in the journal Nature Nanotechnology (“Nanoscale Lateral Displacement Arrays for Separation of Exosomes and Colloids Down to 20nm”), the IBM team’s results show size-based separation of bioparticles down to 20 nanometers (nm) in diameter, a scale that gives access to important particles such as DNA, viruses and exosomes. Once separated, these particles can be analyzed by physicians to potentially reveal signs of disease even before patients experience any physical symptoms and when the outcome from treatment is most positive. Until now, the smallest bioparticle that could be separated by size with on-chip technologies was about 50 times or larger, for example, separation of circulating tumor cells from other biological components.

A Freaky Anti-Rubber Is Still Weirding Scientists Out

Posted by in categories: biotech/medical, computing, transportation

Imagine you wake up one morning burning to make the great physicist Max Planck’s face out of copper. (Just go with it.) Sure, you could sculpt it, but there’s a better way. Cut a flat copper sheet into a half-oval, and take a triangle out of the center of its straight edge. Divide it into smaller triangles, bend the sheet so that the two sides of the big triangle touch—and violà! A sheet of flat copper triangles has morphed to match every nook and cranny of Planck’s face. No sculpting required.

If that sounds like magic … well, that’s understandable, because we left a few steps out. Computer scientist Keenan Crane from Carnegie Mellon University actually did this with real copper, and you can see a computer model of the final product at the top of this article. Making Planck’s face wasn’t the point, of course: When Crane cut the sheet into carefully-designed triangles, he brought it into a class of materials known as auxetics, whose curious and complex properties have excited researchers for decades. Someday, auxetics could improve highway shock absorbers, form more comfortable and versatile shoes, and line veins that thicken when expanding.

At least, that’s what the grant applications say. “People give a lot of lip service to how it’s gonna change the world, in terms of curing cancer,” says Crane. “But at this stage people are still trying to figure out just basic questions.” Auxetics all started with a 1987 Science paper by engineer and professor Roderic Lakes. He reported a new kind of polymer foam that contradicted common sense. It expanded in one direction when stretched in another, and contracted in one direction when squeezed in another.

Apple’s new app to help you do deep breathing to improve your mind, intelligence, and over all health.


APPLE is set to launch a new app that aims to make you healthier through just a few minutes a day of deep breathing.

It is based on the growing field of research proving the biological benefits, including genetic changes, of mind-body medicine.

Scientists Complete the Most Detailed Map of the Brain Ever

Posted by in categories: biotech/medical, neuroscience

To me, maps always conjure up a sense of exploration.

Back in the Age of Discovery, rudimentary maps allowed European explorers to sail into the vast unknown. They began charting new worlds, and in turn, made newer maps that helped future generations better understand the lands and seas that cover our world.

Chip-enhanced political candidates coming soon

My new OpEd article for the San Francisco Chronicle on chip implants and transhumanism: http://www.sfchronicle.com/opinion/openforum/article/Chip-en…694149.php They also did a 2-minute video of my presidential campaign: http://bit.ly/2aERJxc


The implant can do all sorts of things, like unlock my electronic house door, act as my password on my computer, and even send a text message when people with the right phone and app come near me. Keys, credit cards, ID cards, medical records and passwords — these are all things that can be replaced by a tiny chip in the hand. If having technology in your bodies sounds wacky, consider the millions of people around the world who have artificial hips or dentures, or deaf people who use cochlear implants to hear sounds. […] former Vice President Dick Cheney famously asked to have the Wi-Fi on his heart valve turned off, just in case terrorists tried to hack it. A company in Sylmar (Los Angeles County) called Second Sight already has FDA approval for bionic eyes.

Education Linked to Brain Tumor Risk

Posted by in categories: biotech/medical, education, health, neuroscience

Education and socioeconomic status have been linked with cancer outcomes, but a new study now links higher education with the development of certain types of cancer.

The large observational study, published in the Journal of Epidemiology and Community Health, reports that a high level of education is associated with an increased risk of brain tumors. The study is based on data from 4.3 million Swedish adults who were monitored between 1993 and 2010. Overall, 5,735 men and 7,101 women developed a brain tumor during the observation period.

Men with at least three years of university-level education had a 19% greater risk of developing gliomas than men with only a compulsory level of education (nine years). Women with the same level of education had a 23% increased risk of gliomas and a 16% increased risk of meningiomas. Marital status and amount of disposable income only slightly affected the risk among men but not among women. Single men had a lower risk of glioma but a higher risk of meningiomas. Occupation also influenced brain tumor risks among men and women: men in professional and management roles had a 20% increased risk of gliomas and a 50% increased risk of acoustic neuromas; women in these roles had a 26% increased risk of gliomas and a 14% increased risk of meningiomas.
