The DRUL saliva assay is safer, more comfortable, and less expensive than comparable COVID screening tools. Now a new study demonstrates that it is at least as sensitive as swab tests, too.
Three-dimensional images of human small ribosomal subunits offer the most detailed explanation for how the cell's protein-making machines are assembled.
Using light beads microscopy, researchers can now capture images of a vast number of cells across different depths in the brain at high speed, with unprecedented clarity.
Animals as small and soft as tardigrades seldom have legs and almost never bother walking. But a new study finds that water bears propel themselves through sediment and soil on eight stubby legs, in a manner resembling that of insects 500,000 times their size.
