How is it possible to move in the desired direction without a brain or nervous system? Single-celled organisms apparently manage this feat without any problems: for example, they can swim towards food with the help of small flagellar tails. How these extremely simply built creatures manage to do this was not entirely clear until now. However, a research team at TU Wien (Vienna) … [Read more...] about Reaching your life goals as a single-celled organism

With state legislatures nationwide preparing for the once-a-decade redrawing of voting districts, a research team has developed a better computational method to help identify improper gerrymandering designed to favor specific candidates or political parties. In an article in the Harvard Data Science Review, the researchers describe the improved mathematical methodology of an … [Read more...] about Open source tool can help identify gerrymandering in voting maps

In 1884, Edwin Abbott wrote the novel Flatland: A Romance in Many Dimensions as a satire of Victorian hierarchy. He imagined a world that existed only in two dimensions, where the beings are 2D geometric figures. The physics of such a world is somewhat akin to that of modern 2D materials, such as graphene and transition metal dichalcogenides, which include tungsten disulfide … [Read more...] about Intersection of 2D materials results in entirely New materials

Determining safe yet effective drug dosages for children is an ongoing challenge for pharmaceutical companies and medical doctors alike. A new drug is usually first tested on adults, and results from these trials are used to select doses for pediatric trials. The underlying assumption is typically that children are like adults, just smaller, which often holds true, but may also … [Read more...] about Better way to determine safe drug doses for children: New research on organ maturation models could lead to improvements in drug development

A KAIST research team has developed a new technology that enables to process a large-scale graph algorithm without storing the graph in the main memory or on disks. Named as T-GPS (Trillion-scale Graph Processing Simulation) by the developer Professor Min-Soo Kim from the School of Computing at KAIST, it can process a graph with one trillion edges using a single … [Read more...] about T-GPS processes a graph with trillion edges on a single computer? Trillion-scale graph processing simulation on a single computer presents a new concept of graph processing

To observe the swift neuronal signals in a fish brain, scientists have started to use a technique called light-field microscopy, which makes it possible to image such fast biological processes in 3D. But the images are often lacking in quality, and it takes hours or days for massive amounts of data to be converted into 3D volumes and movies. Now, EMBL scientists have combined … [Read more...] about Artificial intelligence makes great microscopes better than ever: Machine learning helps some of the best microscopes to see better, work faster, and process more data

Like conductors of a spooky symphony, researchers at the National Institute of Standards and Technology (NIST) have "entangled" two small mechanical drums and precisely measured their linked quantum properties. Entangled pairs like this might someday perform computations and transmit data in large-scale quantum networks. The NIST team used microwave pulses to entice the two … [Read more...] about Quantum drum duet measured

Heart disease can take a number of forms, but some types of heart disease, such as asymptomatic low ejection fraction, can be hard to recognize, especially in the early stages when treatment would be most effective. The ECG AI-Guided Screening for Low Ejection Fraction, or EAGLE, trial set out to determine whether an artificial intelligence (AI) screening tool developed to … [Read more...] about Trial demonstrates early AI-guided detection of heart disease in routine practice

A Rice University laboratory has adapted its laser-induced graphene technique to make high-resolution, micron-scale patterns of the conductive material for consumer electronics and other applications. Laser-induced graphene (LIG), introduced in 2014 by Rice chemist James Tour, involves burning away everything that isn't carbon from polymers or other materials, leaving the … [Read more...] about In graphene process, resistance is useful

Early on in the COVID-19 pandemic, health officials seized on contact tracing as the most effective way to anticipate the virus's migration from the initial, densely populated hot spots and try to curb its spread. Months later, infections were nonetheless recorded in similar patterns in nearly every region of the country, both urban and rural. A team of environmental engineers, … [Read more...] about Mathematical model predicting disease spread patterns
