Researchers have developed a standalone device that converts sunlight, carbon dioxide and water into a carbon-neutral fuel, without requiring any additional components or electricity.

The device, developed by a team from the University of Cambridge, is a significant step toward achieving artificial photosynthesis—a process mimicking the a...

A mystery surrounding the space around our solar system is unfolding thanks to evidence of supernovae found in deep-sea sediments.

Professor Anton Wallner, a nuclear physicist at ANU, led the study which shows Earth has been travelling for the last 33,000 years through a cloud of faintly radioactive dust.

“These clouds could be remnants of previous supernova explosions, a powerful and super bright explosion of a star,” Professor Wallner said.

Professor Wallner conducted the research at the ANU Heavy Ion Accelerator Facility (HIAF). He also holds joint positions at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and Technical University Dresden (TUD) in Germany.

The researchers searched through several deep-sea sediments from two different locations that date back 33,000 years using the...

Excessive consumption of fructose — a sweetener ubiquitous in the American diet — can result in non-alcoholic fatty liver disease (NAFLD), which is comparably abundant in the United States. But contrary to previous understanding, researchers at University of California San Diego School of Medicine report that fructose only adversely affects the liver after it reaches the intestines, where the sugar disrupts the epithelial barrier protecting internal organs from bacterial toxins in the gut.

Developing treatments that prevent intestinal barrier disruption, the authors conclude in a study published August 24, 2020 in Nature Metabolism, could protect th...

Scientists from NUST MISIS have presented an innovative autonomous power source: a compact atomic battery that can last up to 20 years. Due to the original 3D structure of the beta-voltaic element, its dimensions have decreased by 3x.

The original device uses the microchannel 3D structure of a nickel beta-voltaic element. Its peculiarity is that the radioactive element is applied on both sides of the planar p-n junction, which simplifies the cell manufacturing technology, as well as the control of the reverse current that steals the battery power. The special microchannel structure provides an increase in the effective conversion area of the beta radiation by 14 times, which results in an overall increase of current.

“The output electr...
