Researchers make hardened wooden knives that slice through steak

The sharpest knives available are made of either steel or ceramic, both of which are man-made materials that must be forged in furnaces under extreme temperatures. Now, researchers have developed a potentially more sustainable ...

New technology protects authenticity of engineered cell lines

Advances in synthetic biology and genome editing have led to a growing industry to develop customized cell lines for medical research. These engineered cell lines, however, can be vulnerable to misidentification, cross-contamination ...

Converting waste toilet paper into electricity

Chemists at the University of Amsterdam's (UvA) Sustainable Chemistry research priority area, together with colleagues from the Copernicus Institute of Sustainable Development of Utrecht University, have published the first ...

Life support cooked up from lunar rocks

Engineers have successfully shown how water and oxygen can be extracted by cooking up lunar soil, in order to support future Moon bases. A laboratory demonstrator, developed by a consortium of the Politecnico Milano, the ...

Record-breaking chemical reactivity with nanometer-scale sponge

Catalysts are often solid materials whose surface comes into contact with gases or liquids, thereby enabling certain chemical reactions. However, this means that any atoms of the catalyst that are not on the surface serve ...

Peacock colors inspire 'greener' way to dye clothes

"Fast fashion" might be cheap, but its high environmental cost from dyes polluting the water near factories has been well documented. To help stem the tide of dyes from entering streams and rivers, scientists report in the ...
