Researchers harvest energy from radio waves to power wearable devices

Researchers harvest energy from radio waves to power wearable devices
From microwave ovens to Wi-Fi connections, the radio waves that permeate the environment are not just signals of energy consumed but are also sources of energy themselves. An international team of researchers has developed a way to harvest energy from radio waves to power wearable devices. source...

Fast-acting, color-changing molecular probe senses when a material is about to fail

Fast-acting, color-changing molecular probe senses when a material is about to fail
Materials that contain special polymer molecules may someday be able to warn us when they are about to fail, researchers said. Engineers have improved their previously developed force-sensitive molecules, called mechanophores, to produce reversible, rapid and vibrant color change when a force...

California's diesel emissions rules reduce air pollution, protect vulnerable communities

California's diesel emissions rules reduce air pollution, protect vulnerable communities
Since 1990, California has used its authority under the federal Clean Air Act to enact more aggressive rules on emissions from diesel vehicles and engines compared to the rest of the U.S. Extending these standards to the rest of the U.S. could dramatically improve the nation's air quality...

Ancient megafaunal mutualisms and extinctions as factors in plant domestication

Ancient megafaunal mutualisms and extinctions as factors in plant domestication
The development of agriculture is often thought of as a human innovation in response to climate change or population pressure. A new manuscript challenges that concept, suggesting that plants that had already evolved adaptive traits for life among large-bodied grazing and browsing animals...

Dow-like index for energy prices might help smooth transition to clean power

Dow-like index for energy prices might help smooth transition to clean power
Since the early industrial revolution in the mid-1700s, fossil fuels have acquired an ever-growing footprint in energy production. However, the environmental concerns of fossil fuels use and their inevitable depletion have led to a global shift toward renewable energy sources. These transitions,...

Waste from making purple corn chips yields a natural dye, supplements, kitty litter

Waste from making purple corn chips yields a natural dye, supplements, kitty litter
The more colorful a food, the more nutritious it probably is. For example, purple corn contains compounds associated with a reduced risk of developing diabetes and heart disease. The cobs contain the same compounds but are typically thrown out. Now, researchers report a step-wise biorefinery...
