Plutonium has captured the attention of scientists since its discovery in the early 1940s. This enigmatic element has an important role to play in emerging energy technologies like nuclear batteries and reactors, but it also has complicated electronic behavior that causes some intriguing effects. Its electron structure contributes to unconventional entropic properties at low temperatures […]

Adults with ADHD lose nearly a decade of life

By Invited Researcher

Attention deficit and hyperactivity disorder, known as ADHD, is the most common neurodevelopmental disorder in children worldwide, with an estimated prevalence of around 5%. Research shows that the condition often continues into adulthood in up to 90% of diagnosed children . Although ADHD has been recognised for decades, it has recently gained much greater visibility […]

A new study has revealed potential chemical signatures of ancient Martian microbial life in rocks examined by NASA’s Perseverance rover. The findings, published by a large international team of scientists, focus on a region of Jezero Crater known as the Bright Angel formation—a name chosen from locations in Grand Canyon National Park because of the […]

New non-volatile memory platform built with covalent organic frameworks

New non-volatile memory platform built with covalent organic frameworks

Chemistry

By Mapping Ignorance

Researchers at Institute of Science Tokyo have created a new material platform for non-volatile memories using covalent organic frameworks (COFs), which are crystalline solids with high thermal stability. The researchers successfully installed electric-field-responsive dipolar rotors into COFs. Due to the unique structure of the COFs, the dipolar rotors can flip in response to an electric […]
