International research makes progress towards improved materials for quantum sensor technology

Boron nitride is a technologically interesting material because it is very compatible with other two-dimensional crystalline structures. It therefore opens up pathways to artificial heterostructures or electronic devices ...

DIY microfluidic tool climbs to the top of the charts

A student's side project created to optimize his lab work has piqued the interest of the global scientific community, putting it in the top 10 chemistry papers published in Scientific Reports in 2020.

China's bitcoin mining rush risks derailing climate goals

China's electricity-hungry bitcoin mines that power nearly 80 percent of the global trade in cryptocurrencies risk undercutting the country's climate goals, a study in the journal Nature Communications said on Tuesday.

Deep learning networks prefer the human voice—just like us

The digital revolution is built on a foundation of invisible 1s and 0s called bits. As decades pass, and more and more of the world's information and knowledge morph into streams of 1s and 0s, the notion that computers prefer ...

Ancient atmospheric oxygen sleuthing with ocean chromium

Found in jewelry, car parts, pigments, and industrial chemical reactions, the metal chromium and its compounds are often employed for their color, finish, and anti-corrosive and catalytic properties. Currently, geoscientists ...

A safer way to deploy bacteria as environmental sensors

In recent years, scientists have developed many strains of engineered bacteria that can be used as sensors to detect environmental contaminants such as heavy metals. If deployed in the natural environment, these sensors could ...

Toward a better understanding of 'fake news'

Duncan Watts, a Penn Integrates Knowledge Professor and computational social scientist with appointments in the Annenberg School for Communication, School of Engineering and Applied Science and the Wharton School, has published ...

Finding gene neighbors leads to new protein functions

Access to sequenced genomes was a watershed moment in life science research. Genome sequences spell out an organism's DNA, the genetic code for how the organism develops, reproduces, and functions. As new technologies have ...

Nepal hit by worst wildfires in almost a decade

Nepal is experiencing its worst fire season in almost a decade, officials said Tuesday, as huge blazes rage across the country's forests, engulfing the Himalayan nation in a shroud of brownish haze.

New wasp species discovered in Norway

Cuckoo wasps—also called emerald wasps—are some of the most beautiful insects we have, with colorful exteriors that shine like jewels. However, these beauties have also created a lot of headaches.

Tibetan Plateau will warm faster than expected

The Tibetan Plateau, known as 'the roof of the world,' has warmed more rapidly than global average in the past decades. The observed warming of the Tibetan Plateau since 1960s can be attributed to human activities, particularly ...

Distinctive MJO activity during 2015/2016 super El Nino

El Niño-Southern Oscillation (ENSO) is one of the most prominent ocean-atmosphere interactions that varies year-to-year. This process exerts significant impacts on global weather and climate. El Niño is the warm phase of ...
