Research by the Atacama Cosmology Telescope collaboration has put the standard model of cosmology through a rigorous new set of tests and show it to be remarkably robust. The new images of the early universe, which show both the intensity and polarization of the earliest light with unprecedented clarity, reveal the formation of ancient, consolidating clouds of hydrogen and helium that later developed into the first galaxies and stars.

Some notoriously difficult to treat infections may not be as resistant to antibiotics as has been thought, according to new research using a microfluidic device that more closely duplicates the fluid flow found in the body than standard cultures. The researchers hope that testing samples under flow conditions can improve antibiotic screening and development.
