Researchers at the University of Wisconson have built an energy-harvesting technology that’s particularly well suited for capturing the energy of human motion to power mobile electronic devices. The technology could enable a footwear-embedded energy harvester that captures energy produced by humans during walking and stores it for later use. Power-generating shoes could be especially useful …
Nature reports that the First cancer-fighting virus has been approved. An engineered herpesvirus that provokes an immune response against cancer has become the first treatment of its kind to be approved for use in the United States, paving the way for a long-awaited class of therapies. On 27 October, the US Food and Drug Administration …
Engineering backup copies of mitochondrial genes to place in the nucleus of the cell, aiming to prevent age-related damage and restore lost mitochondrial function. This is attacking one of seven kinds of known aging damage. Each cell in the body is dependent on the efficient generation of cellular energy by mitochondria to stay alive. Critical …
The Gerald R. Ford-class aircraft carrier is now $6 billion over budget and will fall years behind schedule. The program is now $6 billion over budget, according to a review by McCain’s staff. And while the lead ship is expected to be delivered next year, the second ship in the fleet is five years behind …

A new kind of nanoscale rectenna (half antenna and half rectifier) can convert solar and infrared into electricity, plus be tuned to nearly any other frequency as a detector. Right now efficiency is only one percent, but professor Baratunde Cola and colleagues at the Georgia Institute of Technology (Georgia Tech, Atlanta) convincingly argue that they …
China is ready to launch its first domestically built aircraft carrier, known as the Type 001A, on Dec. 26 to mark the 122th birthday of Mao Zedong, according to Hong Kong newspaper Ming Pao. President Xi Jinping reportedly visited the Dalian Shipyard to inspect the progress of work on the carrier in August. Previous reports …
Researchers have developed a method for printing optical holographic lenses that could greatly simplify their fabrication. Because the method can be performed quickly and easily, it could potentially be used by astronauts to print lenses while in space for holographic lens telescopes. While current holographic lens fabrication methods are often expensive, time-consuming, and labor-intensive, the …
The Center for International Marine Security considers a battleship style ship design with armor and a dozen railguns. The CARN (cruiser gun armor, nuclear powered) will need to adapt the principles of the ‘armored citadel’ concepts developed a century ago for battleships to the needs of securing the two, possibly three, nuclear reactors aboard and …
The Emdrive has been proposed as a propellantless space propulsion. NASA had investigated and found measurable propulsion. Now German researchers Emdrive experiments have eliminated other possible sources of error and still measure a small (20 micronewtons) of propulsive force. There is a lot of discussion of the Emdrive experiment on the NASA space flight forum. …
A grand transformation is underway. A wave of decentralization is sweeping across the globe and changing the way we live, work and play. Distributed power technologies are more widely available, smaller, more efficient and less costly today than they were just a decade ago. The portfolio of distributed power technologies includes diesel and gas reciprocating …
