Exploring people's perception of geometric features, personalities and emotions in videos with virtual humans
Researchers at Pontifical Catholic University of Rio Grande do Sul have recently carried out a study aimed at evaluating people's perceptions of geometric features, personalities and emotions presented in video sequences with virtual humans. Their study, outlined in a paper pre-published on arXiv, merges computer science tools with psychology research practices.

Earliest evidence of the cooking and eating of starch
New discoveries made at the Klasies River Cave in South Africa's southern Cape, where charred food remains from hearths were found, provide the first archaeological evidence that anatomically modern humans were roasting and eating plant starches, such as those from tubers and rhizomes, as early as 120,000 years ago.

Polymers jump through hoops on pathway to sustainable materials
Recyclable plastics that contain ring-shaped polymers may be a key to developing sustainable synthetic materials. Despite some promising advances, researchers said, a full understanding of how to processes ring polymers into practical materials remains elusive. In a new study, researchers identified a mechanism called "threading" that takes place when a polymer is stretched—a behavior not witnessed before. This new insight may lead to new processing methods for sustainable polymer materials.

Early dengue virus infection could 'defuse' Zika virus
"We now know for sure that Zika virus infection during pregnancy can affect the unborn foetus in such a way that the child develops microcephaly and other severe symptoms," explains Prof Felix Drexler, a virologist at Charité who has been developing diagnostic tests for Zika and other viruses at the DZIF. Just a few years ago, pictures of affected newborns were cause for worldwide dismay and perplexity. "However, what we did not understand then was that high incidence of microcephaly seemed to occur particularly in northeastern Brazil," says Drexler. Why are expecting mothers in these regions at a higher risk of developing a severe Zika-associated disease than in other regions? The scientists consequently began to search for cofactors that have an influence on whether a Zika infection during pregnancy will develop fatal consequences or not.

Making the best of sparse information
New findings reported by LMU researchers challenge a generally accepted model of echolocation in bats. They demonstrate that bats require far less spatial information than previously thought to navigate effectively.

Machine learning speeds modeling of experiments aimed at capturing fusion energy on Earth
Machine learning (ML), a form of artificial intelligence that recognizes faces, understands language and navigates self-driving cars, can help bring to Earth the clean fusion energy that lights the sun and stars. Researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) are using ML to create a model for rapid control of plasma—the state of matter composed of free electrons and atomic nuclei, or ions—that fuels fusion reactions.

Dangerous pathogens use this sophisticated machinery to infect hosts
Gastric cancer, Q fever, Legionnaires' disease, whooping cough—though the infectious bacteria that cause these dangerous diseases are each different, they all utilize the same molecular machinery to infect human cells. Bacteria use this machinery, called a Type IV secretion system (T4SS), to inject toxic molecules into cells and also to spread genes for antibiotic resistance to fellow bacteria. Now, researchers at Caltech have revealed the 3-D molecular architecture of the T4SS from the human pathogen Legionella pneumophila with unprecedented details. This could in the future enable the development of precisely targeted antibiotics for the aforementioned diseases.

Machine learning reduces language barriers in global trade, research shows
Machine learning and artificial intelligence have exploded onto the scene in recent years, offering the hope of greater business efficiency. At the same time, researchers have found virtually no empirical evidence supporting the promised strides in labor productivity and economic activity.

Ultra-clean fabrication platform produces nearly ideal 2-D transistors
Semiconductors, which are the basic building blocks of transistors, microprocessors, lasers, and LEDs, have driven advances in computing, memory, communications, and lighting technologies since the mid-20th century. Recently discovered two-dimensional materials, which feature many superlative properties, have the potential to advance these technologies, but creating 2-D devices with both good electrical contacts and stable performance has proved challenging.
