New approach could make invisibility cloaking a very real idea
Researchers have found a new way to make something truly invisible to sight. An article in Science Daily describes a new technology that changes the color of light waves as they go through an object, preventing it from giving off reflections or distortions that would reveal the cloaked object. Its developers claim that their approach […]

“Magic” alloy will allow solar cells to capture near-infrared light
A team of researchers from the University of Michigan has taken the next step in solar energy technology. Specifically, they’ve developed a new semiconductor alloy that can capture near-infrared light. In addition to being easier and cheaper to manufacture, ScienceDaily.com reported that the semiconductor alloy is also compatible with the semiconductors utilized in concentrator photovoltaics. […]

Engineers introduce an actuating material that radically changes the concept of motor-driven robots
The robots of the future will change out their big, bulky actuators for something more in line with organic muscles. Chinese engineers have come up with actuating materials that can change their volume depending on the signal they receive, an article on Science Direct reported. Actuators are parts that control and move an object. For […]

New prototype nuclear battery packs 10x more energy than commercial chemical cells
A troika of Russian research institutes have developed a new battery that use nuclear material as its energy source. In a Phys.org article, the prototype cell can store 10 times more energy than its chemical equivalents on the commercial market. The nuclear battery use nickel-63, a radioactive isotope of nickel. Their diodes are made from high-grade diamonds. […]

Research team finds a way to cheaply create nanotubes made from carbon dioxide extracted out of the air
Potentially toxic carbon dioxide can now be transformed into invaluable carbon nanotubes. In a Science Direct article, researchers from Tennessee have reported creating a prototype device that can absorb CO2 from the air and turn it into “black gold.” Carbon nanotubes possess a strength that exceeds steel and a conductivity superior to commonly used copper. […]

Canadian scientists attempt to build quantum radar that can detect stealth aircraft
Canadian researchers are working on an experimental “quantum radar” that can spot the increasingly numerous stealth aircraft deployed by hostile nations. A Live Science article stated that the new radar will use quantum-entangled photons instead of radio waves. The Canadian arctic is not a good workplace for radar. It holds the Earth’s magnetic north pole, […]

Scientists have developed new semiconductors that are more environmentally friendly
Concerned with the prevalence of useful but toxic perovskites in photovoltaic cells, a group of Iowa-based researchers devised alternative materials. They reported creating cheaper and eco-friendly semiconductors with similar performance, according to a ScienceDaily article. Perovskites are light-gathering materials used as semiconductors in solar panels. While highly efficient – called “wonder materials” by the solar […]

Praise for the proton: Latest battery breakthrough may free us from lithium ion
We may finally be on the verge of a true alternative to costly lithium-ion batteries that rely on rare earth metals. Australian researchers recently debuted the first working example of a carbon-based rechargeable proton battery, according to an article on ScienceDaily. According to the RMIT University (RMIT) research team, their proton battery works in tandem […]

A quantum approach to time could reduce memory requirements for future computer simulation models
Computer simulations are extremely useful for scientists who are trying to research by giving them the ability to use models that can make their work easier. Typically, computer models are developed by the scientists themselves while trying to work with the inherent limitations of whatever computer is available for their use. But new research suggests […]

Could 5,000 pencil-shaped robots help solve the mysteries of our universe?
At 45 years of age, the decades-old Nicholas U. Mayall Telescope was due for an upgrade. This four-meter reflector telescope will be given just that this year. Though instead of a new eyepiece or objective lens, the Nicholas U. Mayall Telescope was instead outfitted with about 5,000 fiber optic sensor-equipped, pencil-sized robots. By adding these […]
