Falling module prices have helped to bring down the cost of solar installations, but now balance of system (BOS) components like racking and mounting are key targets of cost reduction, as distributed generation system prices fall by between 15% and 30% by 2020 depending on geography, according to Lux Research.
Along with continuing module efficiency improvements, these advances will… read more
MIT and Harvard University have released a series of working papers (open access) based on 17 online courses offered on the edX platform.
Run in 2012 and 2013, the courses analyzed drew upon diverse topics — from ancient Greek poetry to electromagnetism — and an array of disciplines, from public health to engineering to law.
The working paper series features detailed reports… read more
European scientists from six institutes and two universities have developed an online platform where robots can learn new skills from each other worldwide — a kind of “Wikipedia for robots.”
The objective is to help develop robots better at helping elders with caring and household tasks.
“The problem right now is that robots are often developed specifically for one task”, says René van de Molengraft, TU/e researcher and… read more
Argonne National Laboratory researchers have found a new, more efficient, less-expensive way to make fuel — principally, hydrogen — from sunlight and water: linking a synthetic cobalt-containing catalyst to an organic light-sensitive molecule called a chromophore.
Chromophore molecules, such as chlorophyll, are involved in capturing light for photosynthesis.
Currently, the most efficient methods we have for making fuel involve rare and expensive metal catalysts, such… read more
Researchers with Berkeley Lab and the University of California (UC) Berkeley have created tactile sensors from composite films of carbon nanotubes and silver nanoparticles similar to the highly sensitive whiskers of cats and rats.
The new “e-whiskers” respond to pressure as slight as a single Pascal, about the pressure exerted on a table surface by a dollar bill. Among their potential applications is giving robots new abilities to “see”… read more
Researchers at UC Santa Cruz (UCSC) have developed a robotic “nanobiopsy” system that can extract tiny samples from inside a living cell without killing it.
The single-cell nanobiopsy technique is a powerful tool for scientists working to understand the dynamic processes that occur within living cells, according to Nader Pourmand, professor of biomolecular engineering in UCSC’s Baskin School of Engineering.
“We can take a biopsy from… read more
What’s likely to be the “next big thing?” What might be the most fertile areas for innovation? Where should countries and companies invest their limited research funds? What technology areas are a company’s competitors pursuing?
To help answer those questions, researchers, policy-makers and R&D directors study patent maps, which provide a visual representation of where universities, companies and other organizations are protecting intellectual property produced by their research. But… read more
MIT researchers have come up with a new approach to transparent displays that could have significant advantages over existing systems for certain kinds of applications: wide viewing angle, simplicity of manufacture, and potentially low cost and scalability.
Transparent displays have a variety of potential applications — such as the ability to see navigation or dashboard information while looking through the windshield of a car or plane, or… read more
The deadline for the OpenBCI Kickstarter, an open-source EEG brain-computer interface, is Wednesday Jan. 22 at 8:00pm EST. As of post time (Jan. 22 at 3:29 a.m. EST), $194,520 has been pledged (almost doubling the $100,000 goal), with 866 backers.
“If we reach $200K, we will host … and fund … one domestic and one international hackathon in addition to those funded through the hackathon reward levels … in… read more
A carbon nanotube sponge capable of soaking up water contaminants such as fertilizers, pesticides and pharmaceuticals more than three times more efficiently than previous efforts has been presented in a new study published January 17 in IOP Publishing’s journal Nanotechnology.
The carbon nanotube (CNT) sponges, uniquely doped with sulphur, also demonstrated a high capacity to absorb oil, potentially opening up the possibility of using the material in… read more
MIT Media Lab professor emeritus Marvin Minsky, PhD, 86, a pioneer in the field of artificial intelligence, has won the BBVA Foundation Frontiers of Knowledge Award in the information and communications technologies category.
The BBVA Foundation cited his influential role in defining the field of artificial intelligence, and in mentoring many of the leading minds in today’s artificial intelligence community. The award also recognizes his… read more
University of Illinois engineers have developed tiny “bio-bot” hybrid machines that swim like sperm, the first synthetic structures that can traverse the viscous fluids of biological environments on their own, according to the engineers.
The devices are modeled after single-celled creatures with long tails called flagella — for example, sperm. The researchers begin by creating the body of the bio-bot from a flexible polymer. Then they culture heart cells… read more
Astronomers have discovered a distant quasar illuminating a vast nebula of diffuse gas, revealing, for the first time, part of the network of filaments thought to connect galaxies in a cosmic web.
Researchers at the University of California, Santa Cruz led the study, published January 19 in Nature.
Using the 10-meter Keck I Telescope at the W. M. Keck Observatory in Hawaii, the researchers detected a… read more
Have you ever Googled for an online diagnosis before visiting a doctor? If so, you may have helped provide early warning of an infectious disease epidemic.
In a new study published in Lancet Infectious Diseases, Internet-based surveillance has been found to detect infectious diseases such as Dengue Fever and Influenza up to two weeks earlier than traditional surveillance methods, according to Queensland University of Technology (QUT) research… read more
DOE Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have discovered that sodium bismuthide can exist as a form of matter called a “three-dimensional topological Dirac semi-metal” (3DTDS).
“A 3DTDS is a natural three-dimensional counterpart to graphene with similar or even better electron mobility and velocity,” says Yulin Chen, a physicist with Berkeley Lab’s Advanced Light Source (ALS) when he initiated the study that led to this discovery,… read more
