COLLEGE PARK, Md. — Engineers at the University of Maryland have found a way to make wood more than ten times times stronger and tougher than before, creating a natural substance that is stronger than many titanium alloys. (more…)
Groundbreaking observations could help develop better, more efficient materials for electronics and alternative energy
Using a state-of-the-art ultrafast electron microscope, University of Minnesota researchers have recorded the first-ever videos showing how heat moves through materials at the nanoscale traveling at the speed of sound.(more…)
By using common materials found pretty much anywhere there is dirt, a team of Michigan State University researchers have developed a new thermoelectric material.
This is important, they said, because the vast majority of heat that is generated from, for example, a car engine, is lost through the tail pipe. It’s the thermoelectric material’s job to take that heat and turn it into something useful, like electricity. (more…)
Researchers at Yale University have developed a novel nanoparticle with promising applications in gene therapy, a type of medical treatment that addresses the root causes of diseases now typically treated for symptoms.
The advance could lead to new therapies for many forms of cancer, including brain tumors, as well as for cystic fibrosis and Huntington’s Disease. (more…)

Researchers from North Carolina State University have found a way to optimize the development of DNA self-assembling materials, which hold promise for technologies ranging from drug delivery to molecular sensors. The key to the advance is the discovery of the “Goldilocks” length for DNA strands used in self-assembly – not too long, not too short, but just right.
DNA strands contain genetic coding that will form bonds with another strand that contains a unique sequence of complementary genes. By coating a material with a specific DNA layer, that material will then seek out and bond with its complementary counterpart. This concept, known as DNA-assisted self-assembly, creates significant opportunities in the biomedical and materials science fields, because it may allow the creation of self-assembling materials with a variety of applications.
But, while DNA self-assembly technology is not a new concept, it has historically faced some significant stumbling blocks. One of these obstacles has been that DNA segments that are too short often failed to self-assemble, while segments that are too long often led to the creation of deformed materials. This hurdle can lead to basic manufacturing problems, as well as significant changes in the properties of the material itself. (more…)
