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 ...

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 ...

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 ...

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 ...

Advanced mouse embryos grown outside the uterus

To observe how a tiny ball of identical cells on its way to becoming a mammalian embryo first attaches to an awaiting uterine wall and then develops into nervous system, heart, stomach and limbs: This has been a highly-sought ...

Determining traits from genes

Advanced technologies allow scientists to decipher information about genes faster and more accurately than ever before. But bridging the gap between the genome and how it will be expressed has proven challenging. Scientists ...

Researchers take two steps toward green fuel

An international collaboration led by scientists at Tokyo University of Agriculture and Technology (TUAT) , Japan, has developed a two-step method to more efficiently break down carbohydrates into their single sugar components, ...

Tapping into 100-year supply of natural gas

It is a figure that has been thrown around quite a bit lately in the energy debate – the United States has enough energy in shale to provide all of the nation's transportation fuels for 100 years. But two challenges remain ...
