Open source tool can help identify gerrymandering in voting maps

With state legislatures 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 a recent article, researchers describe the improved mathematical methodology of an open source tool called Gerrychain, which can help observers...

We need to build more EV fast-charging stations, researchers say

A team of engineers recommends expanding fast-charging stations for electric vehicles as campuses and businesses start planning for a post-pandemic world. The recommendation is based on a study of charging patterns for electric vehicles on the University of California San Diego campus from early January to late May of 2020, after the university moved most of its operations online. Researchers say...

Rapid rovers, speedy sands: Fast-tracking terrain interaction modeling

Granular materials, such as sand and gravel, are an interesting class of materials. They can display solid, liquid, and gas-like properties, depending on the scenario. But things can get complicated in cases of high-speed vehicle locomotion, which cause these materials to enter a "triple-phase" nature, acting like all three fundamental phases of matter at the same time.

New, almost non-destructive archaeogenetic sampling method developed

An Austrian-American research team (University of Vienna, Department Evolutionary Anthropology and Harvard Medical School, Department of Genetics), in collaboration of Hungarian experts from Eötvös Loránd University, has developed a new method that allows the almost non-destructive extraction of genetic material from archeological human remains. The method allows anthropologists, archeologists...
