Soil-powered fuel cell promises cheap, sustainable water purification

Engineers at the University of Bath have demonstrated the potential of soil microbial fuel cells (SMFCs) to purify water in field tests in North-East Brazil. SMFCs can generate energy from microorganisms naturally present in soil, which are able to transfer electrons outside their cells.

Specific and rapid expansion of blood vessels

Scientists have discovered a novel mechanism to increase arterial diameter by selectively increasing endothelial cell size, allowing for rapid increases in blood flow. This approach has significant advantages over conventional angiogenesis methods, enabling faster restoration of blood flow and oxygen delivery.

Direct observation of a single electron's butterfly-shaped distribution in titanium oxide

Researchers at Nagoya University have directly observed the spatial distribution of a single valence electron in titanium oxide, revealing a butterfly-shaped distribution. The new Fourier synthesis method, called core differential Fourier synthesis (CDFS), can determine orbital states in materials regardless of their physical properties.
