Is there a unifying principle underpinning animal locomotion in its rich diversity? The thermodynamic analysis shows why and how waste minimization prevails on efficiency or power maximization when it comes to free locomotion irrespective of the available mode and gaits.
A team from the Diverfarming project has found microplastics in 92% of the faeces of sheep fed in intensive agricultural zones of Murcia that they analysed
A team of scientists has succeeded in visualizing how carbon dioxide (CO2) behaves in an ionic liquid that selectively absorbs CO2. The finding is expected to help develop more efficient methods to capture CO2 in the atmosphere, one of the major factors causing global warming.
An international team of scientists, spanning 45 institutions in 17 countries, has called for a dedicated decade-long programme of research to greatly advance discovery in the deep ocean.
US pollution regulations meant to protect humans from dirty air are also saving birds. So concludes a new continentwide study published today in The Proceedings of the National Academy of Sciences. Study authors found that improved air quality under a federal program to reduce ozone pollution may have averted the loss of 1.5 billion birds during the past 40 years.
Researchers at Helmholtz Zentrum München together with scientists across Europe developed a novel animal-free method to predict the toxic effect of nanoparticles to the human lung. The method aims to enable the safety-by-design development of safer industrial materials.
An interdisciplinary team from the University of Geneva and the ETH Zürich spin-off Meteodat investigated possible interactions between acutely elevated levels of fine particulate matter and the virulence of the coronavirus disease. Their results suggest that high concentrations of particles less than 2.5 micrometers in size may modulate, or even amplify, the waves of SARS-CoV-2 contamination and explain in part the particular profile of the COVID-19 pandemic.
A new technique to make cheaper more efficient biological enzyme hybrids could have valuable applications in future water recycling, targeted drug manufacturing and other industries, Flinders University green chemistry researchers say in a new publication. The model enzyme system, which immobilises a catalyst enzyme hybrid for continuous flow use in the high-speed vortex fluidic device, showed a 16-fold increase in its efficiency, the researchers say in American Chemical Society journal, ASC Applied Materials & Interfaces.
Researchers from Tokyo Metropolitan University have realized high-throughput production of thin, ordered through-hole membranes of titanium dioxide. Titania layers were grown using anodization on mask-etched titanium before being crystallized. Applying a second anodization, they converted part of the layer back to an amorphous state. The amorphous portion was then selectively dissolved to free the film while leaving the template intact. This paves the way for industrial production of ordered titania membranes for photonics.
Researchers from the University of Plymouth's International Marine Litter Research Unit have identified the highest recorded microplastics ever found on Earth - at an altitude of more than 8,000 metres, close to the summit of Mount Everest.
