Unanticipated economic benefits from the shale oil and gas boom could help offset the costs of substantially reducing the U.S.'s carbon footprint, Purdue Univ. agricultural economists say. Wally Tyner and Farzad Taheripour estimate that shale technologies annually provide an extra $302 billion to the U.S. economy relative to 2007, a yearly "dividend" that could continue for at least the next two decades, Tyner said.
Rice Univ. scientists have won a race to find the crystal structure of the first virus known to infect the most abundant animal on Earth. The Rice laboratories of structural biologist Yizhi Jane Tao and geneticist Weiwei Zhong, with help from researchers at Baylor College of Medicine and Washington Univ., analyzed the Orsay virus that naturally infects a certain type of nematode, the worms that make up 80% of the living animal population.
Massachusetts Institute of Technology chemical engineers have devised a new implantable tissue scaffold coated with bone growth factors that are released slowly over a few weeks. When applied to bone injuries or defects, this coated scaffold induces the body to rapidly form new bone that looks and behaves just like the original tissue.
While the powerful solvents known as ionic liquids show great promise for liberating fermentable sugars from lignocellulose and improving the economics of advanced biofuels, an even more promising candidate is on the horizon—bionic liquids. Researchers at the Joint BioEnergy Institute have developed “bionic liquids” from lignin and hemicellulose, two by-products of biofuel production from biorefineries.
As climate change alters habitats for birds and bees and everything in between, so too does the way humans decide to use land. Researchers have, for the first time, found a way to determine the potential combined impacts of both climate and land-use change on plants, animals and ecosystems across the country.
Using a microengineered device that acts as an obstacle course for cells, researchers have shed new light on a cellular metamorphosis thought to play a role in tumor cell invasion throughout the body. The epithelial-mesenchymal transition (EMT) is a process in which epithelial cells, which tend to stick together within a tissue, change into mesenchymal cells, which can disperse and migrate individually.
Imitation, they say, is the sincerest form of flattery, but mimicking the intricate networks and dynamic interactions that are inherent to living cells is difficult to achieve outside the cell. Now, as published in Science, Weizmann Institute scientists have created an artificial, network-like cell system that is capable of reproducing the dynamic behavior of protein synthesis.
A convergence of factors is propelling a market rollout of the hydrogen fuel cell vehicle, according to a new study. A key to hydrogen’s potential success is a new smart solution that clusters hydrogen fuel infrastructure in urban or regional networks, limiting initial costs and enabling an early market for the technology before committing to a full national deployment.
Electronic devices with unprecedented efficiency and data storage may someday run on ferroelectrics—remarkable materials that use built-in electric polarizations to read and write digital information, outperforming the magnets inside most popular data-driven technology. But ferroelectrics must first overcome a few key stumbling blocks, including a curious habit of "forgetting" stored data.
The human brain harbors far more copper, iron and zinc than anywhere else in the body. Abnormally high levels of these metals can lead to disorders such as Alzheimer’s and Parkinson’s diseases. Chris Chang, a faculty chemist with Berkeley Lab’s Chemical Sciences Div., has spent the past several years developing new probes and techniques for imaging the molecular activity of these metals in the brain.
It makes sense that the credit for science papers with multiple authors should go to the authors who perform the bulk of the research, yet that’s not always the case. Now a new algorithm developed at Northeastern’s Center for Complex Network Research helps sheds light on how to properly allocate credit.
Amid a neuroscience debate about how people and animals focus on distinct objects within cluttered scenes, some of the newest and best evidence comes from the way bats “see” with their ears, according to a new paper. In fact, the perception process in question could improve sonar and radar technology. Bats demonstrate remarkable skill in tracking targets such as bugs through the trees in the dark of night.
The first analysis of space dust collected by a special collector onboard NASA’s Stardust mission and sent back to Earth for study in 2006 suggests the tiny specks, which likely originated from beyond our solar system, are more complex in composition and structure than previously imagined. The analysis opens a door to studying the origins of the solar system and possibly the origin of life itself.
Thanks to a $1.5 million innovation award from the Gordon and Betty Moore Foundation, Rice Univ. physicist Emilia Morosan is embarking on a five-year quest to cook up a few unique compounds that have never been synthesized or explored. Morosan is no ordinary cook; her pantry includes metals, oxides and sulfides, and her recipes produce superconductors and exotic magnets.
This could be a classic win-win solution: A system proposed by researchers at Massachusetts Institute of Technology recycles materials from discarded car batteries—a potential source of lead pollution—into new, long-lasting solar panels that provide emissions-free power. The system is based on a recent development in solar cells that makes use of a compound called perovskite.
