Graphene is a single-layer of carbon atoms bound together in a chemical pattern. It can have 300 times the strength of steel, and significantly more conductive ability than today’s semiconductors. And, being made of carbon atoms, it can be produced from abundant resources at what may someday be very low prices.
The result: flexible, wearable, [...]
The New Scientist magazine is reporting on an intriguing and brazen new Pentagon program that would create living “OrthopterNets”, communication networks made of insects implanted with special technologies to modulate their wingbeats. Crickets, cicadas and katydids, all use their wings to generate sounds, the patterns of which communicate information to others of their kind. The Pentagon wants to use this natural communications network to prompt the insects to emit specific sounds in the presence of specific chemicals.
A new reverse touchscreen, a ‘see-through’ prototype that allows users to contact objects on-screen from behind the screen, mitigating the problem of hand or fingers blocking out part of the graphics. This makes the screen a more precise navigational interface for users and makes it easier to use multiple fingers at once. The new device will allow for much more agile use of personal electronic devices and possibly for further miniaturization of advanced graphics-intensive tools.
Scientists have achieved the goal of creating a nano-scale “chemical brain” that can transmit instructions to multiple (at present as many as 16) molecular “machines” simultaneously. The new molecular processor means that nano-chemical computation may soon be possible, ushering in a new era in super-light, super-fast, more versatile computer processing capabilities and, by extension, robotics.
When John Kanzius found himself facing aggressive and debilitating chemotherapy treatment for advanced leukemia, seeing the effect the treatment had on fellow patients, he decided to find a better way. Kanzius had worked for decades with radio technology, and understood that radio waves could pass harmlessly through the body. He also knew they could heat metal even at low frequencies.
Space flora or “xflora”, a category of synthetic biochemical organism, engineered to exist in floating colonies in space, combines nano-technology with and biotechnology. While it sounds near impossible, the concept is to create organisms that can feed from their environment, even where that environment would be deadly (for chill, high radiation or lack of nutrients) to Earthborne organisms, and that can be harvested freely as future “off-Earth” human colonies or transports may require.
The Hot Spring connects people to brainstorm, solve problems, and build a more just, more sustainable future.
