IBM researchers used a new nanopatterning technique to create the "world' smallest" 3D map of the Earth. Approximately 1000 of them would fit on a single grain of salt. Separately, they also carved out a 25-nanometer tall model of the Matterhorn. A nanometer, of course, is one-billionth of a meter, so that's a 1:5 billion scale nano-mountain.
From IBM Research:
The core component of the new technique, which was developed by a team of IBM scientists, is a tiny, very sharp silicon tip measuring 500 nanometers in length and only a few nanometers at its apex...
The tip, similar to the kind used in atomic force microscopes, is attached to a bendable cantilever that controllably scans the surface of the substrate material with the accuracy of one nanometer–a millionth of a millimeter. By applying heat and force, the nano-sized tip can remove substrate material based on predefined patterns, thus operating like a "nanomilling" machine with ultra-high precision.
A group of tech firms will meet today to plan the filing of an amicus brief in support of lawsuit to challenge U.S. President Donald Trump’s “Muslim Ban.” Trump’s order was issued on Friday, and restricts immigration from seven Muslim-majority countries in which Trump has no business interests. Adjacent Muslim-majority nations in which Trump does […]
The World Economic Forum asked “leaders from business, government, academia and nongovernmental and international organizations” to take a survey on the potential risks and benefits of different emerging technologies. They seemed to think the space technologies will have little benefit and pose little risk. Energy capture, storage, and transmission has the great promise and little […]
The graphene temporary tattoo seen here is the thinnest epidermal electronic device ever and according to the University of Texas at Austin researchers who developed it, the device can take some medical measurements as accurately as bulky wearable sensors like EKG monitors. From IEEE Spectrum: Graphene’s conformity to the skin might be what enables the […]

Although there will never be a consensus about the best way to make coffee, any coffee connoisseur will agree that controlling the grind of your beans and balancing water temperature are the keys to a tasty cup. Since your plastic coffee pot doesn’t really allow for that kind of customization, going back to the French […]
