Cryo-electron microscopy (cryo-EM) can help scientists determine the three-dimensional structure of proteins in unprecedented ...

The study used stool samples from five healthy volunteers to grow ex vivo gut microbiome cultures. These cultures were then exposed to five common microplastic types—polystyrene, polypropylene, ...

More than 70% of microplastics found in samples from oceans and rivers could come from the scientists collecting them. A new article investigates procedural contamination when sampling for ...

Nearly 50 years have passed since NASA collected samples of the Moon during the Apollo missions of the late 1960s and 1970s. Now, the government space agency has finally chosen to study them, with the ...

Liquid chromatography–mass spectrometry (LC-MS) has become the most popular technique for proteomics analysis. In this strategy, proteins of a sample are typically separated by PAGE and then digested ...

This study was looking at using samples of hair collected from people who were in clinical trials of new cancer drugs. The researchers wanted to know if they could use hair to find out more about how ...

Doctors usually want to run tests on blood samples as quickly as possible, before they start to degrade. As it turns out, such a practice may not be necessary. Scientists conducting experiments with a ...
