New technique allows "nanobiopsies" of living cells

(Phys.org) —Researchers at UC Santa Cruz have developed a robotic "nanobiopsy" system that can extract tiny samples from inside a living cell without killing it. The single-cell nanobiopsy technique is a powerful tool for ...

Direct 'writing' of artificial cell membranes on graphene

Graphene emerges as a versatile new surface to assemble model cell membranes mimicking those in the human body, with potential for applications in sensors for understanding biological processes, disease detection and drug ...

New approach to boosting yeast's ethanol yields

Yeast are commonly used to transform corn and other plant materials into biofuels such as ethanol. However, large concentrations of ethanol can be toxic to yeast, which has limited the production capacity of many yeast strains ...

Cells use sugars to communicate at the molecular level (Update)

The human body is made up of 30 to 40 trillion cells, a large and complex network of blood cells, neurons, and specialized cells that make up organs and tissues. Until now, figuring out which mechanisms control communication ...

A 'door' into the mitochondrial membrane

Mitochondria—the organelles responsible for energy production in human cells—were once free-living organisms that found their way into early eukaryotic cells over a billion years ago. Since then, they have merged seamlessly ...

How plants interact with beneficial microbes in the soil

Scientists have wondered for years how legumes such as soybeans, whose roots host nitrogen-fixing bacteria that produce essential plant nutrients out of thin air, are able to recognize these bacteria as both friendly and ...
