New active filaments mimic biology to transport nano-cargo

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

Very interesting read. The researchers created a completely artificial microscopic transport system mimicking the human body. With this technology we’re going to be able to address many areas of healthcare as well as some areas of AI.


Inspired by micro-scale motions of nature, a group of researchers at the Indian Institute of Technology Madras and the Institute of Mathematical Sciences, in Chennai, India, has developed a new design for transporting colloidal particles, tiny cargo suspended in substances such as fluids or gels, more rapidly than is currently possible by diffusion.

Fluid friction determines micro-scale inertia in fluid. This means, for instance, blood cells swimming within blood encounter roughly the same amount of drag that a human would experience attempting to swim through molasses.

Nanowire ‘inks’ enable low-cost paper- or plastic-based printable electronics

Posted by in categories: materials, nanotechnology

Duke University chemists have found that silver nanowire films like these conduct electricity well enough to form functioning circuits without applying high temperatures, enabling printable electronics on materials like paper or plastic. (credit: Ian Stewart and Benjamin Wiley)

By suspending tiny metal nanoparticles in liquids, Duke University scientists can use conductive ink-jet-printed conductive “inks” to print inexpensive, customizable RFID and other electronic circuit patterns on just about any surface — even on paper and plastics.

Printed electronics, which are already being used widely in devices such as the anti-theft radio frequency identification (RFID) tags you might find on the back of new DVDs, currently have one major drawback: for the circuits to work, they first have to be heated to 200° C (392°F) to melt all the nanoparticles together into a single conductive wire.

The Lifeboat Foundation and LEAF join Forces

Posted by in categories: biotech/medical, education, existential risks, life extension, lifeboat, nanotechnology, robotics/AI

I figured they would post it themselves but I got too excited and decided to spread it around.


The Lifeboat Foundation is a nonprofit organization devoted to encouraging the promotion and advancement of science while helping develop strategies to survive existential risks and the possible abuse of technology. They are interested in biotechnology, nanotechnology, robotics and AI and fostering the safe and responsible use of these powerful new technologies. The Life Preserver program is aligned with our mission to promote and develop rejuvenation biotechnology capable of combating age-related diseases.

We believe that a bright future awaits mankind and support the ethical and safe use of new medical technologies being developed today, thus we consider the goals of the Lifeboat Foundation to be compatible with ours and are pleased to move forward with them in official collaboration. As part of our commitment to the ethical progress of medical science LEAF promotes scientific research and learning via our crowdfunding website Lifespan.io and our educational hub at the LEAF website. A number of LEAF board members are already on the Scientific Advisory board for the Lifeboat Foundation and we look forward to working closely with them in the coming year.

IBM predicts five innovations for the next five years

IBM has unveiled its annual “5 in 5” – a list of ground-breaking innovations that will change the way people work, live, and interact during the next five years.

In 1609, Galileo invented the telescope and saw our cosmos in an entirely new way. He proved the theory that the Earth and other planets in our Solar System revolve around the Sun, which until then was impossible to observe. IBM Research continues this work through the pursuit of new scientific instruments – whether physical devices or advanced software tools – designed to make what’s invisible in our world visible, from the macroscopic level down to the nanoscale.

Nano-chimneys can cool circuits

Posted by in categories: chemistry, nanotechnology

Very cool.


A few nanoscale adjustments may be all that is required to make graphene-nanotube junctions excel at transferring heat, according to Rice University scientists.

The Rice lab of theoretical physicist Boris Yakobson found that putting a cone-like “chimney” between the graphene and nanotube all but eliminates a barrier that blocks heat from escaping.

To produce biopharmaceuticals on demand, just add water

Researchers Develop Preprogrammed Silk-Based Solid Materials with Pre-Designed Functions

Posted by in categories: biotech/medical, nanotechnology

Luv this.


Tufts University engineers have created a new format of solids made from silk protein that can be preprogrammed with biological, chemical, or optical functions, such as mechanical components that change color with strain, deliver drugs, or respond to light, according to a paper published online this week in Proceedings of the National Academy of Sciences (PNAS).

Using a water-based fabrication method based on protein self-assembly, the researchers generated three-dimensional bulk materials out of silk fibroin, the protein that gives silk its durability. Then they manipulated the bulk materials with water-soluble molecules to create multiple solid forms, from the nano- to the micro-scale, that have embedded, pre-designed functions.

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.
