Nano-sized discs teach your body to kill cancer cells

Posted by in categories: biotech/medical, nanotechnology

PanARMENIAN.Net — In the future, getting customized cancer treatments might just be a matter of injecting virtually invisible discs into your body, Engadget said.

University of Michigan scientists have had early success testing 10nm “nanodiscs” that teach your body to kill cancer cells. Each disc is full of neoantigens, or tumor-specific mutations, that tell your immune system’s T-cells to recognize those neoantigens and kill them. When you pair them up with immune checkpoint inhibitors (which boost the T-cells’ responses), they can not only wipe out existing tumors, but prevent them from reemerging later.

This testing has been limited to mice so far, but it’s promising. The nanodiscs took 10 days to eliminate tumors, and they shut down identical tumors when they were reinserted 70 days later. For the researchers, the big challenge right now is scaling the tests to see if they still hold up with larger animals. If the approach proves successful with humans, the days of generic cancer solutions might be limited — so long as doctors could get a sample of your cancer, they’d stand a realistic chance of eliminating the disease, Engadget said.

Testing Predictions of the Quantum Landscape Multiverse 2: The Exponential Inflationary Potential [CEA]

Posted by in categories: cosmology, particle physics, quantum physics

The 2015 Planck data release tightened the region of the allowed inflationary models. Inflationary models with convex potentials have now been ruled out since they produce a large tensor to scalar ratio. Meanwhile the same data offers interesting hints on possible deviations from the standard picture of CMB perturbations. Here we revisit the predictions of the theory of the origin of the universe from the landscape multiverse for the case of exponential inflation, for two reasons: firstly to check the status of the anomalies associated with this theory, in the light of the recent Planck data; secondly, to search for a counterexample whereby new physics modifications may bring convex inflationary potentials, thought to have been ruled out, back into the region of potentials allowed by data. Using the exponential inflation as an example of convex potentials, we find that the answer to both tests is positive: modifications to the perturbation spectrum and to the Newtonian potential of the universe originating from the quantum entanglement, bring the exponential potential, back within the allowed region of current data; and, the series of anomalies previously predicted in this theory, is still in good agreement with current data. Hence our finding for this convex potential comes at the price of allowing for additional thermal relic particles, equivalently dark radiation, in the early universe.

The ultrasound market currently stands as a $6 billion global industry.

Contrary to popular perception, the use of ultrasounds for women’s health and pregnancy follow-ups only represents less than 20% of the overall use for healthcare. For example, a diagnostic ultrasound is routinely used to diagnose an assortment of healthcare conditions such as cancer, gall stones, and cardiovascular diseases.

Tesla Autopilot’s new radar technology predicts an accident caught on dashcam;

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

The video of an accident on the Autobahn in the Netherlands caught on the dashcam of a Tesla Model X shows the Autopilot’s forward collision warning predicting an accident before it could be detected by the driver.

With the release of Tesla’s version 8.0 software update in September, the automaker announced a new radar processing technology that was directly pushed over-the-air to all its vehicles equipped with the first generation Autopilot hardware.

This New Self-Healing, Stretchable Material Is Perfect for Wolverine

Posted by in categories: entertainment, materials

Inspired by the comic book character Wolverine, scientists have developed a self-healing, highly stretchable, transparent material that can be used to power artificial muscles.

The end product is a soft, rubber-like material that’s easy to produce at low cost. It can stretch to 50 times its original length, and can heal itself from a scissor cut in the space of 24 hours at room temperature.
