Researchers in Singapore have developed a revolutionary method for creating full-color images with a resolution of 100,000 dpi. The system uses nanometric metal structures and does not require inks or pigments. By comparison, current industrial ink printers and laser printers have a 10,000 dpi limitation.
In the same way that people are demanding when it comes to choosing the mattress they want to sleep on - not too hard, but not too soft - so are cells. In fact, the rigidity of the cellular environment is so important that it can determine whether a stem cell will differentiate into bone or fat, for example. Even if a cell will behave normally or become cancerous.
A prolonged intake of polystyrene nanoparticles, a very common material in food additives and other commonly consumed products, may be more dangerous to health than previously thought, according to a study published in the journal Nature Nanotechnology.
A Southern California company has created Liquipel, one of the most revolutionary inventions for smartphones. It is a chemical protector, made from tiny nanoparticles, that isolates the circuits and other components of mobile phones from any liquid that may fall on the device.
A team of researchers from the University of California, HRL Laboratories and the California Institute of Technology has developed the lightest material in the world, approximately 100 times lighter than extruded polystyrene (marketed under the brand name Styrofoam), which until now held the record. The new material contains 99.99% air and only 0.01% solids.
That nanotechnology is one of the most powerful technologies that human beings have created in recent centuries is something that Tim Harper, from Cientifica.com, made very clear yesterday to those attending the debate on "The future of nanotechnology" at EmTech Spain. But the most important thing, he stressed, is that to work well on the scale of atoms and molecules we have had - and will have - to learn from nature.
Smart cities, video games, biotechnology, space robotics, nanotechnology ... Smart cities, video games, biotechnology, space robotics, nanotechnology ... The EmTech conference, which for more than a decade has been the great annual event of the Technology Review publication, of the Massachusetts Institute of Technology (MIT), lands this month for the first time in Spain to talk about the technological future that awaits us.
At the University of Michigan (USA) they have created a new type of screen pixel, which works at the same time as a photovoltaic cell. The invention could increase the efficiency of screens in mobile phones and electronic book reading devices, among other applications.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
