Inhibition of HER2 on tumor cells

Posted by in categories: biotech/medical, nanotechnology

A particularly aggressive, metastasizing form of cancer, HER2-positive breast cancer, may be treated with nanoscopic particles “imprinted” with specific binding sites for the receptor molecule HER2. As reported by Chinese researchers in the journal Angewandte Chemie, the selective binding of the nanoparticles to HER2 significantly inhibits multiplication of the tumor cells.

Mind-Uploading: The Impending Meta-System Transition of Humanity

Posted by in categories: biological, engineering, genetics, nanotechnology, neuroscience

The most probable mainstream non-invasive way to transfer human consciousness in the intermediate future, with initial stages in the 2030s, could be the convergence of optogenetics, nanotechnologies, neuroengineering, Cloud exocortex and an array of neurotechnologies allowing to connect our wetware directly to the Cloud.

Initially, each of us will have a personal exocortex in the Cloud, the third non-biological “de-cerebral” hemisphere, which will be in constant communication with the other two biological brain hemispheres.

At some point, this “third hemisphere,” will have a threshold information content and intimate knowledge of your biology, personality and other physical world attributes in order to seamlessly integrate with your persona as a holistic entity.

MIT’s Nano-Magnets Can Clean Up Oil Spills

Posted by in categories: government, nanotechnology, robotics/AI, sustainability

Oil spill cleanup technology is a surprisingly innovative field—we learned as much in the wake of the BP Gulf disaster, when everyone from conservation biologists to barbers to Kevin Costner rushed to sell the government on their wild, sometimes literally hairy oil-sucking solutions. We had rubber goop that turned oil solid, massive bags of hair, and MIT’s previous entry into the cleanup fray, robotic oil-eating submarines.

But now the renowned science lab has a better idea: nano-magnets.

MIT researchers have developed a new technique for magnetically separating oil and water that could be used to clean up oil spills. They believe that, with their technique, the oil could be recovered for use, offsetting much of the cost of cleanup.

2029: The Year Humanity Has Become a Race of the Immortals

Posted by in categories: biotech/medical, life extension, nanotechnology, robotics/AI

We’re now rapidly approaching a pivotal moment in the history of this planet, when through scientific discovery an intelligent species could become a race of demigods, THE RACE OF THE IMMORTALS.

It’s quite achievable now. In fact, that will probably happen in two stages: First stage — we have to extend our lifespan with ever-improving Biotechnology. Aging is declared a desease, and around 2029, with the advances in Nanotechnology and Artificial Intelligence, we will be able start to reverse aging and add more than one year every year to an average life expectancy.

So if you’re alive in 2030, chances are you’ll live to 100 and beyond. What life would be like on the other side, when you know you can live indefinitely long? Well, we’ll get used to it and adjust accordingly. We’ll merge into the Global Brain, and emerge as the Global Mind.

Physicists Discover Entirely New Quantum States When Graphene Meets Itself

Posted by in categories: nanotechnology, quantum physics

The super-thin ’wonder material’ graphene has been shaking up science for years with its amazing properties, but things get really interesting when you stack this 2D nanomaterial up against itself.

In new experiments, physicists in the US have found that when graphene is assembled in a double-layer vertical stack – with two adjacent sheets of the material that are almost touching – the proximity produces quantum states that haven’t been observed before.

These newly measured states, resulting from complex interactions of electrons between the two graphene layers, are examples of what’s called the fractional quantum Hall effect – and it’s just the latest example of how physical science gets weird when materials effectively only occupy two dimensions.

Generation of extreme-ultraviolet beams with time-varying orbital angular momentum

Posted by in categories: nanotechnology, particle physics

Structured light beams can serve as vortex beams carrying optical angular momentum and have been used to enhance optical communications and imaging. Rego et al. generated dynamic vortex pulses by interfering two incident time-delayed vortex beams with different orbital angular momenta through the process of high harmonic generation. A controlled time delay between the pulses allowed the high harmonic extreme-ultraviolet vortex beam to exhibit a time-dependent angular momentum, called self-torque. Such dynamic vortex pulses could potentially be used to manipulate nanostructures and atoms on ultrafast time scales.

New holographic technique opens the way for quantum computation

Posted by in categories: entertainment, holograms, nanotechnology, quantum physics

Photography measures how much light of different color hits the photographic film. However, light is also a wave, and is therefore characterized by the phase. Phase specifies the position of a point within the wave cycle and correlates to depth of information, meaning that recording the phase of light scattered by an object can retrieve its full 3D shape, which cannot be obtained with a simple photograph. This is the basis of optical holography, popularized by fancy holograms in sci-fi movies like Star Wars.

But the problem is that the spatial resolution of the photo/hologram is limited by the wavelength of light, around or just-below 1 μm (0.001 mm). That’s fine for macroscopic objects, but it starts to fail when entering the realm of nanotechnology.
