Solar power has been gaining more and more popularity worldwide since the efficiency of solar panels has significantly increased during the recent years, along with the dramatic decrease in the costs. However, its popularity is not only due its affordability to a wider audience but also to the growing awareness about the benefits of clean sources of energy. Yet, the costs of transportation and production often make it extremely difficult to implement solar technology in developing countries. Printed solar cells could offer a solution to this problem.

Thanks to the advances in printed solar cell technology during the past few years, its energy efficiency has increased from 3% to 20%.

“Its success is due to its cost-effectiveness and simplicity. A 10×10 cm solar cell film is enough to generate as much as 10–50 watts per square meter,” said Scott Watkins from the Korean company Kyung-In Synthetic.

Researchers from Bilkent University, Ankara, Turkey, have shown that twisting straight nanowires into springs can increase the amount of light the wires absorb by up to 23 percent. Absorbing more light is important because one application of nanowires is turning light into electricity, for example, to power tiny sensors instead of requiring batteries.

If nanowires are made from a semiconductor like silicon, light striking the wire will dislodge electrons from the crystal lattice, leaving positively charged “holes” behind. Both the electrons and the holes move through the material to generate electricity. The more light the wire absorbs; the more electricity it generates. (A device that converts light into electricity can function as either a solar cell or a photosensor.)

Meeting the basic needs of humanity is increasingly brought into question as we begin to resemble a cancer to the living organism we inhabit. As mass extinction continues to become an omnipotent reality, it’s apparent that more humans equals more problems. To fix this, we have to approach them in the same way farmers do: with resiliency. Farmers try to nurture their crops and hope for the right season. Although, even the predictability of spring, summer and fall’s outcome can be misleading. Nature has a way of leading things in the exact opposite direction than they seem to be headed. And it is those who’ve treaded, but still embark that truly encounter the rewards. For if farmers were to give up after an adverse season, there’d be no food next year. There’d be no continuity of supply for society. There’d be no method of feeding the hungry. No solution to ease the growing population and its rising demands.

So, with exponential gain in human births this century, how do we combat such problems? One possible solution is to build “green skyscrapers” for the sole purpose of farming, where we are able to control the environment and have multiple levels of plant growth. This could be done by utilizing an array of mirrors to redirect sunlight to every floor, while supplementing with multi-spectral, energy-efficient LED’s. With advanced humidity control and water-recycling techniques, we’d contribute towards the global conservation of water and open up valuable land to reforestation — all through subjugating the unpredictability of nature. This ensures the utmost quality and care goes into producing local, high-quality food, with the added benefit of honing the technology needed for interplanetary colonization.

Right now, the most powerful physics machine ever constructed by man is running at maximum power after a major upgrade that took two years to complete.

And recently, two different experiments reported that they may have discovered a particle that behaves in ways that cannot be explained with any existing physical laws, as Scientific American reports.

Shown below is one of four major detectors that are crucial to the machine’s purpose:

Intel Corporation introduced the 6th Generation Intel® Core™ processor family, the company’s best processors ever. The launch marks a turning point in people’s relationship with computers. The 6th Gen Intel Core processors deliver enhanced performance and new immersive experiences at the lowest power levels ever and also support the broadest range of device designs – from the ultra-mobile compute stick, to 2 in 1s and huge high-definition All-in-One desktops, to new mobile workstations.

There are over 500 million computers in use today that are four to five years old or older. They are slow to wake, their batteries don’t last long, and they can’t take advantage of all the new experiences available today.

Built on the new Skylake microarchitecture on Intel’s leading 14nm manufacturing process technology.

California – Apple Inc. (NASDAQ:AAPL) has filed a patent application for a fuel cell system that could power a MacBook or an iPhone “for days or even weeks without refueling”. With batteries dying fast around the world the technology industry hasn’t been able to solve the problem entirely. But now the bitten fruit company has given the first step into what seems to be the cutting edge generation of battery design.

After the U.K based company, Intelligent Energy revealed an iPhone version packed with a prototype hydrogen fuel cell that would last for a week before needing to be charged, rumors began to resonate about close colaboration with Apple to include such technologies in their own products. And as it turns out, the patent presented by Apple in March confirms exactly that. However, this controversial fuel cells will need to be replaced once they have depleted.

A few lines in a seemingly routine RAND Corp. report on the future of technology and law enforcement last week raised a provocative question: Should police have the power to take control of a self-driving car?

Human drivers are required to pull over when a police officer gestures for them to do so. It’s reasonable to expect that self-driving cars would do the same. To look at it another way: Self-driving cars are programmed to stop at red lights and stop signs. Surely they should also be programmed to stop when a police officer flags them down. It is, after all, the law.

It’s clear, then, that police officers should have some power over the movements of self-driving cars. What’s less clear is where to draw the line. If a police officer can command a self-driving car to pull over for his own safety and that of others on the road, can he do the same if he suspects the passenger of a crime? And what if the passenger doesn’t want the car to stop—can she override the command, or does the police officer have ultimate control? – Slate, Aug. 24, 2015

Our view of civil rights has to evolve as technology changes our lives. More often than not, the changes are for the worse. Fifty years ago, could the police enter your home without a warrant and review your family photos for criminal evidence? No, and they still can’t today – though, of course, we know they do. However, they can order Facebook to give them access to photos you shared only with your selected friends.
