A team of researchers led by Gen Suwa of the University of Tokyo has used statistical methods to calculate when canine teeth in modern male humans began to shrink down to their current size. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of hundreds of ancient fossil teeth.

Enzymes maintain a range of protein sequences and diverse structural forms with activities that far exceed the best chemical catalysts. However, research on engineering them with new and improved features are limited due to technical inadequacies. In a new report now published in Nature Communications, Linfeng Xu and a research team in bioengineering, chemistry, and molecular biology at the University of California, the University of Michigan, and the University of Texas, in the U.S., described a...

Devices that can automatically detect and recognize moving objects have numerous valuable applications, for instance, enhancing remote environmental monitoring. Most existing motion detection and recognition (MDR) technologies are based on image sensors made of complementary metal oxide semiconductors (CMOS). Compared to the human retina, these systems are often bulky and ineffective, as they require several hardware components for capturing, storing, and processing images.

Inspired by biological fractals, a team of researchers affiliated with multiple institutions in China has developed a new pore structure for a membrane used to separate uranium from seawater. In their paper published in the journal Nature Sustainability, the group describes their pore structure and how well it worked when tested. Alexander Wiechert and Sotira Yiacoumi with the Georgia Institute of Technology and Costas Tsouris with Oak Ridge National Laboratory, have published a News & Views... Читать дальше...

An international team of astronomers has conducted radio observations of a bow shock in the X-ray binary Vela X-1 using MeerKAT telescope. The observational campaign resulted in the detection of radio emission from this source. The finding is detailed in a paper published November 19 on arXiv.org.

A team of researchers from China and the U.S. has found that it should be possible to dramatically reduce deaths due to air pollution over the coming decades if climate mitigation strategies are designed with short-term health improvements in mind. In their paper published in the journal Nature Climate Change, the group describes their study of the most hazardous power plants in countries around the world.
