New algorithm makes maps of gene activity easier to compare while preserving cell-level detail
Spatial transcriptomics can reveal where thousands of genes are active across a tissue, creating molecular maps at single-cell resolution. But comparing two such maps is difficult…
Animals may have evolved vastly earlier than fossil evidence suggests
The earliest animals may have evolved hundreds of millions of years before their first unmistakable fossils appear in the fossil record, according to a new study led by the Univer…
Physicists who uncovered the first particle accelerator were honored with a Nobel Prize 75 years ago
While scientists are known for their dedication to their research, crawling on the floor to avoid electrocution for the sake of a measurement seems a little excessive. But this is…
Fluorescent test speeds screening of thousands of enzyme variants that modify plant compounds
Many natural plant compounds have promising health-related properties, but their poor water solubility can limit how effectively they are absorbed and used. In previous work, rese…
Millions of years of evolution guide AI search for pollution-fighting enzymes
Databases around the world contain information on millions upon millions of enzymes that have the potential to degrade pollutants like plastic. Scientists at Murdoch University's …
