Solar cell polymers with multiplied electrical output
One challenge in improving the efficiency of solar cells is that some of the absorbed light energy is lost as heat. So scientists have been looking to design materials that can convert more of that energy ...
First contracting human muscle grown in laboratory
In a laboratory first, Duke researchers have grown human skeletal muscle that contracts and responds just like native tissue to external stimuli such as electrical pulses, biochemical signals and pharmaceuticals.
'Glowing' new nanotechnology guides cancer surgery, also kills remaining malignant cells
Researchers at Oregon State University have developed a new way to selectively insert compounds into cancer cells - a system that will help surgeons identify malignant tissues and then, in combination with ...
Toyota to give away fuel-cell patents to boost industry
Toyota will give away thousands of patents for its fuel-cell cars, it said Tuesday, in an effort to encourage other automakers into the new industry.
Improved solar panels and printed electronics on the horizon with new discovery
New and improved solar panels could result from the discovery of a new liquid crystal material, making printable organic solar cells better performing.
'Flying carpet' technique uses graphene to deliver one-two punch of anticancer drugs
(Phys.org)—An international team of researchers has developed a drug delivery technique that utilizes graphene strips as "flying carpets" to deliver two anticancer drugs sequentially to cancer cells, with ...
Self-assembled nanotextures create antireflective surface on silicon solar cells
Reducing the amount of sunlight that bounces off the surface of solar cells helps maximize the conversion of the sun's rays to electricity, so manufacturers use coatings to cut down on reflections. Now scientists ...
Live imaging captures how blood stem cells take root in the body
A see-through zebrafish and enhanced imaging provide the first direct glimpse of how blood stem cells take root in the body to generate blood. Reporting online in the journal Cell today, researchers in Bos ...
Perovskites provide big boost to silicon solar cells
Stacking perovskites onto a conventional silicon solar cell dramatically improves the overall efficiency of the cell, according to a new study led by Stanford University scientists.
How the code of life passed through primitive kinds of cells
Life's origins are a mystery, but every year scientists get a little bit closer to understanding what made life possible on Earth, and possibly on other planets or moons.
'CRISPR' science: Newer genome editing tool shows promise in engineering human stem cells
A powerful "genome editing" technology known as CRISPR has been used by researchers since 2012 to trim, disrupt, replace or add to sequences of an organism's DNA. Now, scientists at Johns Hopkins Medicine have shown that ...
How cells communicate
During embryonal development of vertebrates, signaling molecules inform each cell at which position it is located. In this way, the cell can develop its special structure and function. For the first time ...
Mechanical engineer seeks to make solar cells competitive
One day in the 1990s, as he was riding home from high school in São Paulo, Tonio Buonassisi looked out the bus window at the Brazilian city's long lines of traffic, and its smoggy haze. In that moment, he ...
Japan researchers target 3D-printed body parts
Japanese scientists say they are on their way to being able to create custom-made skin, bone and joints using a 3D printer.
