Arxiv – Utilization of H-reversal Trajectory of Solar Sail for Asteroid Deflection Near Earth Asteroids have a possibility of impacting with the Earth and always have a thread on the Earth. This paper proposes a way of changing the trajectory of the asteroid to avoid the impaction. Solar sail evolving in a H-reversal trajectory is …
mages of regenerated lenses after the seventeenth lentectomy. Following along a theme of what some would have called ‘Mad Science’ (the prior article being about a double leg transplant from a cadaver) we have a researcher who removed the lens from an eye of newts 18 times. Fictional Witches should never run out of the …
The artificial trachea after two days of cell growth, and just before being implanted into the patient. Credit: Harvard Bioscience Surgeons in Sweden have successfully transplanted a fully synthetic, tissue-engineered organ—a trachea—into a man with late-stage tracheal cancer. The synthetic trachea was created entirely in the lab, using a scaffold built out of a porous …
Solar dots: Each of these 16 dots is a solar cell made up of nanoscopic particles called quantum dots. Credit: Ted Sargent Technology Review – A research team at the University of Toronto has created the first two-layer solar cell made up of light-absorbing nanoparticles called quantum dots. Quantum dots, which can be tuned to …

It was previously believed that as nanowires became smaller that the the thermoelectric figure of merit would improve, but new work shows that improving heat to electricity conversion in nanowires is not that simple. The prevailing notion that quantum confinement benefits the thermoelectric power factor is supported by the model when a single-subband dominates transport. …
A team of physicists at the University of Innsbruck, led by Philipp Schindler and Rainer Blatt, has been the first to demonstrate a crucial element for a future functioning quantum computer: repetitive error correction. This allows scientists to correct errors occurring in a quantum computer efficiently. The researchers have published their findings in the scientific …
China – US manufacturing cost components from 2008 Within the next five years, the United States is expected to experience a manufacturing renaissance as the wage gap with China shrinks and certain U.S. states become some of the cheapest locations for manufacturing in the developed world, according to a new analysis by The Boston Consulting …
The University of Cambridge has pentagonal tiles which are paving the way towards organic electronics. New research paves way for the nanoscale self-assembly of organic building blocks, a promising new route towards the next generation of ultra-small electronic devices. Ring-like molecules with unusual five-fold symmetry bind strongly to a copper surface, due to a substantial …
NIST measurements show that interactions of the graphene layers with the insulating substrate material causes electrons (red, down arrow) and electron holes (blue, up arrow) to collect in “puddles”. The differing charge densities creates the random pattern of alternating dipoles and electon band gaps that vary across the layers. Credit: NIST Researchers at the National …
At MIT, a host of researchers are exploring how to reinvent chip architecture from the ground up, to ensure that adding more cores makes chips perform better, not worse. One way to improve communication between cores, which the Angstrom project is investigating, is optical communication — using light instead of electricity to move data. Though …
