How nanotechnology could detect and treat cancer

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

The crew of the Proteus has one desperate chance to save a man’s life. Shrunk to the size of a large bacterium, the submarine contains a team of scientists and physicians racing to destroy a blood clot in the brain of a Soviet defector. The group journeys through the body, evading giant white blood cells and tiny antibodies while traveling through the heart, the inner ear and the brain to reach and destroy the blockage.

Although events in the film Fantastic Voyage were far-fetched when it was released in 1966, they’re now being realized every day in labs around the world, particularly in cancer treatment. A growing field called nanotechnology is allowing researchers to manipulate molecules and structures much smaller than a single cell to enhance our ability to see, monitor and destroy cancer cells in the body.

Tens of thousands of patients have already received chemotherapy drugs delivered by nanoparticles called liposomes, and dozens of other approaches are currently in clinical trials. Within the next five to 10 years, our bodies’ biggest defenders may be tinier than we could have ever imagined.

Seeding space with nanosatellites for affordable Internet

Posted by in categories: internet, satellites

Luv this as long as it doesn’t pollute space.

Space seeds could bring high-bandwidth Internet connectivity to the globe at less expense than the cost of putting one satellite into space.

Magnetic Hyperbolic Optical Metamaterial Could Advance Thermophotovoltaics

Posted by in categories: energy, nanotechnology, physics

Improving energy efficiencies — nice.

The remarkable properties researchers at the Australian National University (ARC Centre of Excellence CUDOS) and the University of California Berkeley have discovered in a new nano-metamaterial could lead to highly efficient thermophotovoltaic cells. The new artificial material glows in an unusual way when headed.

As shown in the image, the metamaterial comprises 20 stacked alternating layers of 30-nm-thick gold and 45-nm-thick magnesium fluoride dielectric, perforated with 260 × 530 nm holes that are arranged into a 750 × 750 nm square lattice.

The bionic skin that can feel a tumor

Posted by in categories: biotech/medical, cyborgs, neuroscience, transhumanism


Our skin is our largest organ. A gateway between our brain and the rest of the world.

Imagine then a scene where skin could communicate what’s going on inside a human body. It could inform surgeons, provide alerts when our body is about to fall ill, or even diagnose diseases inside another human being, simply through the sense of touch.

A Barefoot Run Might Be a Brain Booster

Posted by in categories: health, neuroscience

The next time that you decide to run barefoot in the rain, etc. there is a health benefit that you’re receiving in the form of enhancing your brain.

FRIDAY, May 13, 2016 (HealthDay News) — Runners who want to boost their brain function should consider taking their running shoes off, new research suggests.

The study found that after running barefoot, participants saw improvements in working memory, or the ability to recall or process information. Running in shoes, however, didn’t result in the same advantage, researchers said.

Theorists smooth the way to modeling quantum friction

Posted by in categories: chemistry, computing, information science, particle physics, quantum physics

Theoretical chemists at Princeton University have pioneered a strategy for modeling quantum friction, or how a particle’s environment drags on it, a vexing problem in quantum mechanics since the birth of the field. The study was published in the Journal of Physical Chemistry Letters (“Wigner–Lindblad Equations for Quantum Friction”). “It was truly a most challenging research project in terms of technical details and the need to draw upon new ideas,” said Denys Bondar, a research scholar in the Rabitz lab and corresponding author on the work.

Researchers construct a quantum counterpart of classical friction, a velocity-dependent force acting against the direction of motion

Researchers construct a quantum counterpart of classical friction, a velocity-dependent force acting against the direction of motion. In particular, a translationary invariant Lindblad equation is derived satisfying the appropriate dynamical relations for the coordinate and momentum (i.e., the Ehrenfest equations). Numerical simulations establish that the model approximately equilibrates. (© ACS)

The US military is creating brain implants to restore lost memories

Posted by in categories: government, military, neuroscience

So, the US Military has developed a way to eliminate bad memories/ PTSD and another method to restore memories. Wish the US Government would make their minds up on this one — LOL.

A scientist in DARPA’s biological technologies offices explains how the agency is developing implants that could bring back memories.

DARPA Has a Simple Plan to Clean Up the World’s Deadliest Weapons

Posted by in categories: government, law, military

US Government may have discovered a new method of safely getting rid of old chemical and other old stockpile weapons.

Getting rid of chemical weapons is one of the military’s most unpleasant duties. But in the future, it may be no more difficult than incinerating garbage, thanks to a team of DARPA-funded scientists who think they can turn some of the world’s deadliest poisons into harmless dirt.

Chemical weapons, including nerve agents and mustards, have been banned under international law since the 1990s, but many countries still harbor large stockpiles. In 2013, a horrific chemical weapons attack in Syria—called the Ghouta attack —claimed hundreds of civilian lives, prompting the international community to intervene and eliminate the country’s chemical weapons reserves. By August 2014, 600 metric tons of deadly weapons had been destroyed (in the military parlance, “demilitarized”) aboard the US Navy vessel MV Cape Ray.
