Rice Univ. bioengineers have developed a hydrogel scaffold for craniofacial bone tissue regeneration that starts as a liquid, solidifies into a gel in the body and liquefies again for removal. The material developed in a Rice laboratory is a soluble liquid at room temperature that can be injected to the point of need. At body temperature, it turns into a gel to help direct the formation of new bone to replace that damaged by injury.

Univ. of Oregon chemists studying the structure of ligand-stabilized gold nanoparticles have captured fundamental new insights about their stability. The information, they say, could help to maintain a desired, integral property in nanoparticles used in electronic devices, where stability is important.
Zinc is found in every tissue in the body. The vast majority of the metal ion is tightly bound to proteins, helping them to perform biological reactions. Tiny amounts of zinc, however, are only loosely bound, and may be critical for proper function in some organs. Yet the exact roles the ion plays in biological systems are unknown. A new optical sensor tracks zinc within cells and should help researchers learn more about its functions.
Funded by prominent Silicon Valley investors and Microsoft founder Bill Gates, Hampton Creek Foods seeks to disrupt a global egg industry that backers say wastes energy, pollutes the environment, causes disease outbreaks and confines chickens to tiny spaces. The company, which just started selling a mayonnaise made without eggs, is part of a new generation of so-called food-tech ventures that aim to change the way we eat.
Researchers in Lyon, a French city famed for its cuisine, have discovered a quick-cook recipe for copious volumes of hydrogen that involves water, rock, aluminum oxide and extreme pressure. The breakthrough suggests a better way of producing the hydrogen that propels rockets and energizes battery-like fuel cells.
The most tweeted peer-reviewed articles published between 2010 and 2012, and the trends associated with their social media success, have been identified by researchers in Canada. With colleagues in the United States, U.K. and Germany, they took 1.4 million articles held in the PubMed and Web of Science databases and determined how many times they appeared on Twitter.
Innovation is improbable without proper funding, which is why R&D Magazine and Battelle Memorial Institute annually project how political developments and economic conditions around the globe will affect R&D support in the coming year. Now available, the 2014 R&D Magazine/Battelle Global R&D Funding Forecast offers a comprehensive analysis of the state of industrial research worldwide.
Researchers in Singapore and at IBM Research in California have discovered a new, potentially life-saving application for polyethylene terephthalate (PET), which is widely used to make plastic bottles. They have successfully converted PET into a non-toxic biocompatible material with superior fungal killing properties. This could help prevent and treat various fungus-induced diseases such as keratitis.
The chemicals and advanced materials industry consists of large multinational companies serving nearly every other market, key single market material and application development firms and an array of smaller, niche chemical and material companies.
Researchers have combined cutting-edge experimental techniques and computer simulations to find a new way of predicting how water dissolves crystalline structures like those found in natural stone and cement. The research could have wide-ranging impacts in diverse areas, including water quality and planning, environmental sustainability, corrosion resistance and cement construction.
Scientists are reporting development of a squishy gel that, when compressed at a key location such as a painful knee joint, releases anti-inflammatory medicine. The new material could someday deliver medications when and where osteoarthritis patients need it most.
With support from the Photosynthetic Systems Div. at the U.S. Dept. of Energy, researchers in the School of Science at Rensselaer Polytechnic Institute are expanding a successful research program to uncover the minute workings of the photosynthetic protein, Photosystem II. The high-impact research, led by prof. K.V. Lakshmi, seeks to adapt photosynthesis for artificial use as an abundant source of renewable energy.
A team working at the SACLA x-ray Free-Electron Laser in Japan has, for the first time, succeeded in generating ultra-bright, two-color x-ray laser pulses in the hard x-ray region. These light pulses have different wavelengths whose time separation can be adjusted with attosecond accuracy. They could be powerful tools for investigating the structure of matter and the dynamics of ultrafast physical processes and chemical reactions.
Hydrogen is a “green” fuel that burns cleanly and can generate electricity via fuel cells. One way to sustainably produce hydrogen is by splitting water molecules using the renewable power of sunlight, but scientists are still learning how to control and optimize this reaction with catalysts. At the National Synchrotron Light Source, a research group has determined key structural information about a potential catalyst.
A chemical system developed by researchers at the Univ. of Illinois at Chicago can efficiently perform the first step in the process of creating syngas, gasoline and other energy-rich products out of carbon dioxide. A novel “co-catalyst” system using inexpensive, easy-to-fabricate carbon-based nanofiber materials efficiently converts carbon dioxide to carbon monoxide, a useful starting material for synthesizing fuels.
When sunlight strikes a photosynthesizing organism, energy flashes between proteins just beneath its surface until it is trapped as separated electric charges. Improbable as it may seem, these tiny hits of energy eventually power the growth and movement of all plants and animals. They are literally the sparks of life.
Nature builds flawless diamonds, sapphires and other gems. Now a Northwestern Univ. research team is the first to build near-perfect single crystals out of nanoparticles and DNA, using the same structure favored by nature. The research group developed the “recipe” for using nanomaterials as atoms, DNA as bonds and a little heat to form tiny crystals. This single-crystal recipe builds on superlattice techniques.
The presence of molecular hydrogen, in addition to carbon dioxide and water, could have created a greenhouse effect on Mars 3.8 billion years ago that pushed temperatures high enough to allow for liquid water. This is according to a team of researchers who believe this is the only way for giant canyons like Nanedi Valles could have formed.
The research team was inspired by biological processes in species such as amphibians, which can regenerate severed limbs, engineers in Pittsburgh have developed computational models to design a new polymer gel that would enable complex materials to regenerate bulk sections of severed material using nanorods.
The United States is spewing 50% more methane—a potent heat-trapping gas—than the federal government estimates, a new comprehensive scientific study says. Much of it is coming from just three states: Texas, Oklahoma and Kansas. It means methane, which doesn’t stay in the air long but is 21 times more potent at trapping heat than carbon dioxide, may be a bigger global warming issue than thought, scientists say.
Univ. of Illinois researchers have developed a way to heal gaps in wires too small for even the world's tiniest soldering iron. Junctions between nanotubes have high resistance, slowing down the current and creating hotspots. The researchers use these hot spots to trigger a local chemical reaction that deposits metal that nanosolders the junctions.
Chemical engineers at Rice Univ. have found a new catalyst that can rapidly break down nitrites, a common and harmful contaminant in drinking water that often results from overuse of agricultural fertilizers. Nitrites and their more abundant cousins, nitrates, are inorganic compounds that are often found in both groundwater and surface water. The compounds are a health hazard.
Scientists have charted a significant signaling network in a tiny organism that's big in the world of biofuels research. The findings about how a remarkably fast-growing organism conducts its metabolic business bolster scientists' ability to create biofuels using the hardy microbe Synechococcus, which turns sunlight into useful energy.
A unique inside look at the electronic structure of a highly touted metal-organic framework (MOF) as it is adsorbing carbon dioxide gas should help in the design of new and improved MOFs for carbon capture and storage. Researchers with Lawrence Berkeley National Laboratory have recorded the first in situ electronic structure observations of the adsorption of carbon dioxide inside Mg-MOF-74.
For years scientists have intensely argued over whether increases of potent methane gas concentrations in the atmosphere, from about 5,000 years ago to the start of the industrial revolution, were triggered by natural causes or human activities. A new study suggests the increase in methane likely was caused by both.
A team of researchers has uncovered critical information that could help scientists understand how protein polymers interact with other self-assembling biopolymers.
