The U.S. pledged to cut its greenhouse gas emissions up to 28% as part of a global treaty aimed at preventing the worst effects of climate change, the White House said. The Obama administration's contribution to the treaty, which world leaders expect to finalize in December, codifies a commitment President Barack Obama first made late last year in Beijing.
Solar panels, wind turbines, electric vehicles and other power sources are proliferating rapidly, but their reliable integration into the existing electric grid is another story. A new study offers a comprehensive reimagining of the power grid that involves the coordinated integration of small-scale distributed energy resources. The study, asserts that the proliferation of renewable energy must happen at the periphery of the power grid.
Conveying systems for oil and gas, operated in the sea, have many important underwater components. The maintenance of such components is elaborate and expensive, as measuring them is complicated. Fraunhofer researchers are presenting a compact 3-D measurement system at the trade fair in Hannover.
Oil-based liquid crystals are ubiquitous; an understanding of their properties is behind the displays in most electronics. Water-based liquid crystals are less well understood, though their biocompatibility makes them a candidate for a variety of applications. New research has advanced the field's understanding of these materials, demonstrating never-before-seen configurations by confining a water-based liquid crystal in a cylinder.
Have you ever wondered if your dad's fight with prostate cancer means you could face the same reality? Perhaps your family has several members who have struggled with obesity and you wonder if it's something you inherited or if it's caused by the environment. Maybe you have always wanted to learn where your ancestors came from beyond the basic paper trail. Good news: Researchers have an app for that.
When weighing the pluses and minuses of your skin add this to the plus column: Your skin, like that of all vertebrates, is remarkably resistant to tearing. Now, a collaboration of researchers at Lawrence Berkeley National Laboratory and the Univ. of California, San Diego, has shown why.
Dielectric elastomers are novel materials for making actuators or motors with soft and lightweight properties that can undergo large active deformations with high-energy conversion efficiencies. This has made dielectric elastomers popular for creating devices such as robotic hands, soft robots, tunable lenses and pneumatic valves, and possibly flapping robotic wings.
Scientists from ETH Zurich have developed a thermometer that is at least 100 times more sensitive than previous temperature sensors. It consists of a bio-synthetic hybrid material of tobacco cells and nanotubes. Humans have been inspired by nature since the beginning of time. We mimic nature to develop new technologies, with examples ranging from machinery to pharmaceuticals to new materials.
Researchers at the National Univ. of Singapore have discovered that the inherent handedness of molecular structures directs the behavior of individual cells and confers them the ability to sense the difference between left and right. This is a significant step forward in the understanding of cellular biology.
An international research team, led by a Virginia Tech geoscientist, has revealed information about how continents were generated on Earth more than 2.5 billion years ago, and how those processes have continued within the last 70 million years to profoundly affect the planet's life and climate.
Memory and as well as connections between brain cells were restored in mice with a model of Alzheimer’s given an experimental cancer drug, Yale School of Medicine researchers reported in the Annals of Neurology. The drug, AZD05030, developed by Astra Zeneca proved disappointing in treating solid tumors but appears to block damage triggered during the formation of amyloid-beta plaques, a hallmark of Alzheimer’s disease.
Scientists have found a way to measure the unseen toll that environmental stress places on living creatures, showing that they can rev up their metabolism to work more than twice as hard as normal to cope with change. Stresses from climate change such as rising temperatures and increasing ocean acidity can move an organism closer and closer to the brink of death without visible signs.
The decades worth of data that has been collected about the billions of neurons in the brain is astounding. To help scientists make sense of this “brain big data,” researchers at Carnegie Mellon Univ. have used data mining to create www.neuroelectro.org, a publicly available Website that acts like Wikipedia, indexing physiological information about neurons.
Speaking in public is the top fear for many people. Now, researchers from the Human-Computer Interaction Group at the Univ. of Rochester have developed an intelligent user interface for “smart glasses” that gives real-time feedback to the speaker on volume modulation and speaking rate, while being minimally distracting.
To understand when and why volcanoes erupt, scientists study the rocks left behind by eruptions past. A method called geobarometry uses the composition of volcanic rocks to estimate the pressure and depth at which molten magma was stored just before it erupted. A research team has tested a new type of geobarometer that is well-suited to study the kind of magma often produced in explosive and destructive volcanic eruptions.
