Scientists break down tuberculosis structure

Scientists from the University of British Columbia have taken a crucial step towards starving out tuberculosis, following research into how the infection grows in the body.

How the building blocks of life may form in space

In a laboratory experiment that mimics astrophysical conditions, with cryogenic temperatures in an ultrahigh vacuum, scientists used an electron gun to irradiate thin sheets of ice covered in basic molecules of methane, ammonia ...

Custom sequences for polymers using visible light

Researchers from Tokyo Metropolitan University used a light-sensitive iridium-palladium catalyst to make "sequential" polymers, using visible light to change how building blocks are combined into polymer chains. By simply ...

Building the machinery that makes proteins

All of the proteins necessary for life are made by giant molecular machines called ribosomes. A ribosome, in turn, is built from proteins and ribosomal RNAs stitched together with immaculate precision.
