Method uses DNA, nanoparticles and lithography to make optically active structures
Northwestern University researchers have developed a first-of-its-kind technique for creating entirely new classes of optical materials and devices that could lead to light bending and cloaking devices -- news to make the ears of Star Trek's Spock perk up. Using DNA as a key tool, the scientists took gold nanoparticles of different sizes and shapes and arranged them in two and three dimensions to form optically active superlattices. The structures could be programmed to exhibit almost any color across the visible spectrum.

Using data mining to make sense of climate change
Georgia Techhas developed a new way of mining data from climate data sets that is more self-contained than traditional tools. The methodology brings out commonalities of data sets without as much expertise from the user, allowing scientists to trust the data and get more robust -- and transparent -- results.

Semiconductor breakthrough may be game-changer for organic solar cells
In an advance that could push cheap, ubiquitous solar power closer to reality, University of Michigan researchers have found a way to coax electrons to travel much further than was previously thought possible in the materials often used for organic solar cells and other organic semiconductors.

Michigan's sugar maples will struggle in a warmer, drier future despite help from nitrogen pollution
Though Michigan's sugar maples benefit from the growth-promoting effects of nitrogen compounds in the environment, those gains will not fully offset the added stresses of growing under a drier climate in the future, according to a new University of Michigan-led study.

Nature Microbiology
Unexpected environmental source of methane discovered
Roughly 10 percent of nitrogen-fixing microorganisms contain the genetic code for manufacturing a back-up enzyme, called iron iron-only nitrogenase, to do their job. New research reveals that this enzyme allows these microorganisms to convert nitrogen gas to ammonia and carbon dioxide into methane at the same time. This enzymatic pathway is a previously unknown route for the natural biological production of methane.

Bio-based compound offers a greener carbon fiber alternative
From cars and bicycles to airplanes and space shuttles, manufacturers around the world are trying to make these vehicles lighter, which helps lower fuel use and lessen the environmental footprint. But with the industry relying on petroleum products to make carbon fiber today, could we instead use renewable sources?

Tailoring cancer treatments to individual patients
The Center for Computational Oncology developed computer models to predict how cancer will progress in a specific individual, based on tissue, cellular and subcellular protein signaling responses. The models can predict how brain tumors (gliomas) will grow with much greater accuracy than previous models. Recently, the group began a clinical study to predict how an individual's cancer will progress after one cycle of therapy, and to use that prediction to plan the course of treatment.

New grants bolster CSU expertise in wildfire smoke impacts
When wildfires burn, the choking smoke that billows upward has a life of its own. Depending on a multitude of conditions such as wind speed, cloud density and forest type, combustion byproducts move and change unpredictably in the atmosphere. The study of these smoke particles ­-- their size, composition, dispersion and interaction with clouds and atmospheric processes -- has a rich interdisciplinary history at Colorado State University.

Thermally activated delayed photoluminescence from semiconductor nanocrystals
Researchers from North Carolina State University have found that the transfer of triplet excitons from nanomaterials to molecules also creates a feedback mechanism that returns some energy to the nanocrystal, causing it to photoluminesce on long time scales. The mechanism can be adjusted to control the amount of energy transfer, which could be useful in optoelectronic applications.

High-resolution climate models present alarming new projections for US
Approaching the second half of the century, the United States is likely to experience increases in the number of days with extreme heat, the frequency and duration of heat waves, and the length of the growing season. In response, it is anticipated that societal, agricultural and ecological needs will increase the demand on already-strained natural resources like water and energy. University of Illinois researchers have developed new, high-resolution climate models that may help policymakers mitigate these effects at a local level.

Perking up and crimping the 'bristles' of polyelectrolyte brushes
A molecular-sized brush that looks like a shoe brush has properties with great potential for the materials industry and medicine, but polyelectrolyte brushes can be sensitive, and getting them to work right tricky. New research shows what can make them break down, but also what can get them to systematically recover.
