Phys.org / Solar thermal process produces cement with no carbon dioxide emissions
(Phys.org) -- While the largest contributor to anthropogenic greenhouse gas emissions is the power industry, the second largest is the more often overlooked cement industry, which accounts for 5-6% of all anthropogenic CO2 ...
Phys.org / 800-pound paper airplane takes flight
(PhysOrg.com) -- An 800-pound, 45-foot-long paper airplane with a 24-foot wingspan may be the largest paper airplane ever to glide across the sky. After being hoisted to a height of 2,703 feet by a helicopter last Wednesday, ...
Phys.org / Researchers revolutionize closed captioning
(PhysOrg.com) -- Ever since closed video captioning was developed in the 1970s, it hasn't changed much. The words spoken by the characters or narrators scroll along at the bottom of the screen, enabling hearing impaired viewers ...
Phys.org / Cyborg snail produces electricity
(PhysOrg.com) -- First it was grapes, then cockroaches, and now snails have become the latest organism to generate electricity through an implanted biofuel cell. The process works similarly in all three situations: the electricity ...
Phys.org / Maglev track could launch spacecraft into orbit
(PhysOrg.com) -- With the aim to make it easier to launch spacecraft into low Earth orbit (LEO), two researchers have turned to maglev technology to catapult a payload hundreds of miles above the Earth. While the concept ...
Medical Xpress / Shining light in the ears may alleviate SAD symptoms
(Medical Xpress) -- Millions of people experience depression and lower levels of energy in the winter due to seasonal-affective disorder (SAD), or the winter blues. Since the disorder is thought to arise due to ...
Phys.org / LED's efficiency exceeds 100%
(PhysOrg.com) -- For the first time, researchers have demonstrated that an LED can emit more optical power than the electrical power it consumes. Although scientifically intriguing, the results wont immediately result ...
Phys.org / Removing 'black sheep' could make Internet run more efficiently
(PhysOrg.com) -- Whether dealing with Internet traffic or vehicle traffic, congestion can slow everything down. One team of researchers working on improving network transmission efficiency has developed a strategy that identifies ...
Phys.org / Paper highlights need for correctly measuring solar cell efficiency
(PhysOrg.com) -- As the pace of solar cell research continues to accelerate, the question for every new design is whats its efficiency? Since measuring how efficiently a solar cell converts sunlight into ...
Phys.org / Time crystals could behave almost like perpetual motion machines
(PhysOrg.com) -- As every young science student knows, moving objects have kinetic energy. But just how much energy does something need to move? In a new study, a pair of physicists has shown that its theoretically ...
