A $9.4 million grant from the Defense Advanced Research Projects Agency (DARPA) could lead to development of a new technique for wirelessly monitoring Internet of Things (IoT) devices for malicious software – without affecting the operation of the ubiquitous but low-power equipment.
Suddenly, a roundworm overhauls an array of survival strategies all at once, and researchers suspect multiple mutations caused them. But they're surprised when they trace the sweeping changes back to one tiny mutation on a single gene. It's a great hint at a genetic regulator of so-called life history trade-offs, a much observed natural phenomenon.
A new wrinkle on an old technology – solid-state thermophotovoltaics (TPV) – could provide a high-efficiency alternative for directly converting high-temperature heat from concentrated solar thermal to utility-scale electricity.
Time to smash the beaker when thinking about oxygen concentrations in water, at the time when animal life first evolved. Oceans stacked O2 here and depleted it there, as this novel model demonstrates. It may well toss a wrench into the way we have dated the evolution of the earliest animals.
A novel three-dimensional solar cell design will soon get its first testing in space aboard the International Space Station. An experimental module containing 18 test cells was launched to the ISS on July 18, and will be installed on the exterior of the station to study the cells’ performance and their ability to withstand the rigors of space.

A new study from a Georgia Tech-Cornell University team shows that the research faculty path isn’t the only reason students pursue a postdoc.
Project allows people to get move with a computer-controlled dancer, which “watches” the person and improvises its own moves based on prior experiences. When the human responds, the computerized figure reacts again, creating an impromptu dance couple based on artificial intelligence.
Researchers are suggesting seven energy-intensive separation processes they believe should be the top targets for research into low-energy purification technologies. Beyond cutting energy use, improved techniques for separating chemicals from mixtures would also reduce pollution, cut carbon dioxide emissions – and open up new ways to obtain critical resources the world needs.
Researchers believe they've solved the mystery of how oversized microgels shrink to fit colloidal crystals, and what they've learned could also have implications for biological systems made up of soft organic particles not unlike the polymer microgels.
How easily did life arise on Earth, how likely is it on other planets? A new experiment strongly supports the idea that very early life coding molecules, ancestors of RNA and DNA, arose in primordial puddles with relative ease and speed, and not necessarily just in rarer fiery cataclysms.
Phone calls and text messages reach you wherever you are because your phone has a unique identifying number that sets you apart from everybody else on the network. Researchers at the Georgia Institute of Technology are using a similar principle to track cells being sorted on microfluidic chips.
A piece of DNA’s movements are often counterintuitive to those of objects in our everyday grasp. A rod of rubber, for example: Bend it until its ends meet, and you can count on the elastic tension to snap it back straight when you let go. When you bend DNA into a short loop, the elastic energy more often than not wants to bend the chain further in instead of pushing it back out.
Researchers have demonstrated proof of concept for a novel low-energy nuclear reaction imaging technique designed to detect the presence of “special nuclear materials” – weapons-grade uranium and plutonium – in cargo containers arriving at U.S. ports.
Researchers visited Christmas Island, the world's largest coral atoll, to measure the effects of El Nino. Eighty percent of the coral is dead.
Study suggests that powerful volcanic blasts occur due in part to how light vapor bubbles migrate and accumulate in some parts of shallow volcanic chambers. Researchers say these bubbles maneuver their way through crystal filled magma until they settle in these open-spaced reservoirs – areas without many crystals – and build up the necessary energy for an impending eruption.
A new study of more than 50 samples of Vibrio cholerae isolated from both patients and the environment demonstrates the diversity and resourcefulness of the organism.
The human microbiome, a diverse collection of microorganisms living inside us and on our skin, has attracted considerable attention for its role in a broad range of human health issues. Now, researchers are discovering that the built environment also has a microbiome, which includes a community of potentially-pathogenic bacteria living inside water supply pipes.
A new Georgia Tech study finds that Instagram’s decision to ban certain words commonly used by pro-eating disorder (pro-ED) communities has produced an unintended effect. The use of those terms decreased when they were censored in 2012. But users adapted by simply making up new, almost identical words, driving up participation and support within pro-ED groups by as much as 30 percent.
Researchers have launched U.S. News Map, a database of more than 10 million newspaper pages that is helping researchers see history with spatial information that hadn’t been available before. Using digitized newspaper articles and cutting-edge search technology, the project is helping researchers see the nation’s history in new ways.
