Deep sea sediment cores—they’re cold, they’re muddy, and they’re revealing 30,000 years of climate history—as PhD student Julia Gottschalk reports from her voyage aboard the James Cook research ship last summer

Particles of soot floating through the air and comets hurtling through space have at least one thing in common: 0.36. That, reports a research group at the National Institute of Standards and Technology (NIST), is the measure of how dense they will get under normal conditions, and it’s a value that seems to be constant for similar aggregates across an impressively wide size range from nanometers to tens of meters.*

Much as human DNA can be used as evidence in criminal trials, genetic information about microorganisms can be analyzed to identify pathogens or other biological agents in the event of a suspicious disease outbreak. The tools and methods used to investigate such outbreaks belong to an emerging discipline known as microbial forensics, but the field faces substantial scientific and technical challenges, says a new report from the National Research Council.
