How to control friction in topological insulators

Posted by in categories: computing, nanotechnology, quantum physics

Topological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists at the University of Basel and the Istanbul Technical University have begun investigating how they react to friction. Their experiment shows that the heat generated through friction is significantly lower than in conventional materials. This is due to a new quantum mechanism, the researchers report in the scientific journal Nature Materials.

Thanks to their unique electrical properties, promise many innovations in the electronics and computer industries, as well as in the development of quantum computers. The thin surface layer can almost without resistance, resulting in less than traditional materials. This makes them of particular interest for .

Furthermore, in topological insulators, the electronic —i.e. the electron-mediated conversion of electrical energy into heat—can be reduced and controlled. Researchers of the University of Basel, the Swiss Nanoscience Institute (SNI) and the Istanbul Technical University have now been able to experimentally verify and demonstrate exactly how the transition from energy to heat through friction behaves—a process known as dissipation.

Scientists Get Green Light To Bring Back Dead To Life With Stem Cells

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

US biotechnology company called Bioquark has been given permission to recruit 20 clinically dead patients and attempt to bring their central nervous systems back to life. They hope to eliminate patients’ need to rely on machines by reanimating parts of the upper spinal cord, where the lower brain stem is located, to potentially energize vital body functions like breathing and heartbeats.

Trial participants will have been declared certified dead and kept alive solely through life support machines. “This represents the first trial of its kind and another step towards the eventual reversal of death in our lifetime,” said CEO of Bioquark Inc., Ira Pastor.

The team, who has been granted ethical permission from an Institutional Review Board at the National Institutes of Health in the US and India to begin trials on 20 subjects, is looking to recruit patients for its ReAnima Project as soon as possible.

AI-based cytometer detects rare cells in blood using magnetic modulation and deep learning

Posted by in categories: biotech/medical, robotics/AI

Detection of rare cells in blood and other bodily fluids has numerous important applications including diagnostics, monitoring disease progression and evaluating immune response. For example, detecting and collecting circulating tumour cells (CTCs) in blood can help cancer diagnostics, study their role in the metastatic cascade and predict patient outcomes. However, because each millilitre of whole blood contains billions of blood cells, the rare cells (such as CTCs) that occur at extremely low concentrations (typically lower than 100‑1000 cells per millilitre) are very difficult to detect. Although various solutions have been developed to address this challenge, existing techniques in general are limited by high cost and low throughput.

Researchers at UCLA Henry Samueli School of Engineering have developed a new cytometry platform to detect rare cells in blood with high throughput and low cost. Published in Light: Science and Applications, this novel cytometry technique, termed magnetically modulated lensless speckle imaging, first uses magnetic bead labelling to enrich the target cells. Then the enriched liquid sample containing magnetic bead-labelled target cells is placed under an alternating magnetic field, which causes the target cells to oscillate laterally at a fixed frequency. At the same time, a illuminates the sample from above and an positioned below the sample captures a high-frame-rate lensless video of the time-varying optical pattern generated by the sample. The recorded spatiotemporal pattern contains the information needed to detect the oscillating .

The researchers built a compact and low-cost prototype of this computational lensless cytometer using off-the-shelf image sensors, laser diodes and electromagnets, and used a custom-built translation stage to allow the imager unit to scan liquid sample loaded in a glass tube. The prototype can screen the equivalent of ~1.2 mL of whole blood sample in ~7 min, while costing only ~$750 and weighing ~2.1 kg. Multiple parallel imaging channels can also be easily added to the system to further increase sample throughput.

Researchers design a solution for traffic management that helps reduce jams and pollution in cities

Posted by in categories: education, robotics/AI, transportation

A team of researchers from the Universitat Politècnica de València (UPV) and the Université Paul Sabatier-Toulouse III (France) have developed a system that is capable of managing all traffic in a city, which will help to prevent traffic jams while reducing the driving times of vehicles and pollution levels. The system has been designed for autonomous vehicles and includes a route provider service capable of forecasting the present and future density of traffic in the city. It also takes that information into account when choosing new routes. The work has been published in Electronics.

Unlike existing systems that can suggest alternative routes depending on the bottlenecks at a certain time, the new system makes it possible to find out the present and future density of in the entire metropolitan area, and controls traffic as a whole, aiming to minimize or totally eliminate . In addition, it allows including different criteria—environmental, atypical situations, accidents, etc.—to dynamically provide advice about routes.

“Our proposal makes it easier for authorities to restrict or eliminate traffic in a certain area during the time period they find appropriate. For example, reducing traffic next to schools during the entry/exit hours, or in areas where ambulances circulate or an accident has happened, etc.,” explains Carlos Tavares Calafate, researcher at the Networking Research Group-DISCA of the UPV and coordinator of the work.

Spy chip planting said to be easy to do and tough to spot

Posted by in category: cybercrime/malcode

Much too easy: Planting a two-dollar spy chip on hardware with a technique that can be pulled off on a less than $200 budget? Yet that was the work of a proof in concept investigation by a security researcher and tech-watching sites were discussing the story on Monday.

Turns out you can slip a spy chip into any hardware for no more than $198 to $200, said reports. The spotlight was on researcher Monta Elkins, Hacker-in-Chief, FoxGuard Solutions. He has a proof-of-concept version of a hardware implant.

John Dunn, Naked Security, talked about the chip as bad news for security were it to happen. “In fact, this has already happened as part of a project by researcher Monta Elkins, designed to prove that this sort of high-end hardware hack is no longer the preserve of nation-states.”

Get Dr. Bill Andrews on The Joe Rogan Experience

Posted by in categories: biotech/medical, education, life extension

This purpose of this video is to GET DR. BILL ANDREWS ON THE JOE ROGAN EXPERIENCE. You can help make this reality in many ways. Please start by joining the Facebook group: GET DR. BILL ANDREWS ON THE JOE ROGAN EXPERIENCE: https://www.facebook.com/pg/Get-Dr-Bill-Andrews-on-The-Joe-R…e_internal

I believe we can get closer to reversing human aging by finding stronger human telomerase activators if Dr. Bill Andrews/Sierra Sciences receives more funding ($50 million USD would probably be enough for Dr. Andrews and his team to discover stronger human telomerase activators within a year).

Immune to Cancer | Michael Jensen | TEDxStMarksSchool

Posted by in categories: biotech/medical, futurism

What if the future of cancer treatment lies not with stronger drugs and larger doses of radiation that kill cells indiscriminately, but instead harnesses the power of our immune system to destroy cancer cells in our own body? Dr. Michael Jensen shares details of an FDA approved cancer treatment with a 91% cure-rate.

Dr. Michael Jensen is a leader in the field of cancer immunotherapy research. As the founding director of the Ben Towne Center for Childhood Cancer Research at Seattle Children’s Research Institute, Dr. Jensen and his team are pioneering translational research with striking results that just might change the way we think of disease treatment.
