Curved lenses, like those in cameras or telescopes, are stacked in order to reduce distortions and resolve a clear image. That’s why high-power microscopes are so big and telephoto lenses so long.

While lens technology has come a long way, it is still difficult to make a compact and thin lens (rub a finger over the back of a cellphone and you’ll get a sense of how difficult). But what if you could replace those stacks with a single flat—or planar—lens?

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated the first planar lens that works with high efficiency within the visible spectrum of light—covering the whole range of colors from red to blue. The lens can resolve nanoscale features separated by distances smaller than the wavelength of light. It uses an ultrathin array of tiny waveguides, known as a metasurface, which bends light as it passes through, similar to a curved lens.

BOSTON, June 3 (UPI) — Until now, synthetic biological systems have focused exclusively on either analog or digital computation. Researchers at MIT have devised a technique for creating cellular gene circuits capable of complex computation.

Analog computation, also called continuous computation, is the type of processing happening as the human eye adjusts to changing light conditions. Digital computation involves binary decision making, on or off processes.

The new synthetic cellular circuitry designed by MIT scientists performs like a comparator, receiving analog input signals and converting them into digital output signals.

Researchers from the University of Melbourne are developing a minimally invasive brain-machine interface that DARPA hopes to use in fighter jets.

Since 2001, I have worked, experimented, and researched in parallel tech and bio/medical technology space. I did this because I could see that at some point that these two fields would eventually overlap and eventually merge in many areas. Today, we’re already see the duplicated use of technology in both the medical/ life sciences and the same technology used to advance the technology in general such as Quantum tech, nanotech, etc. Here is another example of this trend.

Silicon forms the basis of everything from solar cells to the integrated circuits at the heart of our modern electronic gadgets. However the laser, one of the most ubiquitous of all electronic devices today, has long been one component unable to be successfully replicated in this material. Now researchers have found a way to create microscopically-small lasers directly from silicon, unlocking the possibilities of direct integration of photonics on silicon and taking a significant step towards light-based computers.

Whilst there has been a range of microminiature lasers incorporated directly into silicon over the years, including melding germanium-tin lasers with a silicon substrate and using gallium-arsenide (GaAs) to grow laser nanowires, these methods have involved compromise. With the new method, though, an international team of researchers has integrated sub-wavelength cavities, the basic components of their minuscule lasers, directly onto the silicon itself.

To help achieve this, a team of collaborating scientists from Hong Kong University of Science and Technology, the University of California, Santa Barbara, Sandia National Laboratories and Harvard University, first had to find a way to refine silicon crystal lattices so that their inherent defects were reduced significantly enough to match the smooth properties found in GaAs substrate lasers. They did this by etching nano-patterns directly onto the silicon to confine the defects and ensure the necessary quantum confinement of electrons within quantum dots grown on this template.

Three signature projects being pursued by Verily, Google’s life sciences startup, are plagued by serious scientific challenges, STAT has found.

Elon Musk is known for his optimistic deadlines, but this one is very aggressive.

The Tesla CEO spoke at the Code Conference on Wednesday night and predicted that we’re closer to self-driving cars than anybody thinks. “I think we are less than two years away from complete autonomy, safer than humans, but regulations should take at least another year,” Musk said.

While many auto and tech companies—from Google to Uber and GM to Lyft and Apple to Ford—are researching and testing autonomous vehicles, the Tesla seems on the verge of announcing that its Model 3 consumer sedan will have full self-driving capabilities.
