A team of computer scientists working on two different problems -- how to quickly detect damaged buildings in crisis zones and how to accurately estimate the size of bird flocks -- recently announced an AI framework that can do both. The framework, called DISCount, blends the speed and massive data-crunching power of artificial intelligence with the reliability of human analysis to quickly deliver reliable estimates that can quickly pinpoint and count specific features from very large collections of images.

New research suggests that materials commonly overlooked in computer chip design actually play an important role in information processing, a discovery which could lead to faster and more efficient electronics. Using advanced imaging techniques, an international team found that the material that a semiconductor chip device is built on, called the substrate, responds to changes in electricity much like the semiconductor on top of it.

While there's no regulation in the U.S. for what's in organic shampoos, they tend to contain ingredients perceived as safe or environmentally friendly. However, these 'clean' shampoos separate and spoil faster than those made with synthetic stabilizers and preservatives. Now, researchers demonstrate that a simple process -- spinning organic shampoo at high speeds -- improved the final products' shelf lives and ability to clean hair.

Researchers have developed a novel method of adding polyethylene glycol molecules to engineered groups of messenger RNAs called 'mRNA polyplexes', which enable the cells that receive them to produce specific proteins. This technique allows greater control of the site in the body to which the polyplexes are delivered, significantly advancing the field of therapeutic mRNA technologies, with applications in vaccine development and the treatment of cancer and other diseases.

When scuba divers need to say 'I'm okay' or 'Shark!' to their dive partners, they use hand signals to communicate visually. But sometimes these movements are difficult to see. Now, researchers have constructed a waterproof 'e-glove' that wirelessly transmits hand gestures made underwater to a computer that translates them into messages. The new technology could someday help divers communicate better with each other and with boat crews on the surface.

Wirelessly connected devices perform an expanding array of applications, such as monitoring the condition of machinery and remote sensing in agricultural settings. These applications hold much potential for improving the efficiency, but how do you power these devices where reliable electrical sources are not available? Research points to a possible solution in the form of a novel type of battery.

Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.

Researchers unveiled BeatProfiler, a groundbreaking new tool -- a comprehensive software that automates the analysis of heart cell function from video data. It's the first system to integrate the analysis of different heart function indicators, such as contractility, calcium handling, and force output into one tool, speeding up the process significantly and reducing the chance for errors. BeatProfiler enabled the researchers to not only distinguish between different diseases and levels of their severity but also to rapidly and objectively test drugs that affect heart function.

Did you know that the world's deadliest animal is the mosquito? And Aedes aegypti is one of the most dangerous. This bug spreads viruses that cause dengue fever, which was recently declared as an epidemic in Puerto Rico. Research reports new molecules that label proteins in the unique, alkaline environment of the Ae. aegypti digestive system that could help scientists develop insecticides to fight back.
