Infant formula safety checks can be improved with stratified sampling
Producers of infant formula employ comprehensive food safety systems, including product testing to ensure those systems are working. A new study from the University of Illinois Urbana-Champaign finds that some testing methods are more powerful at catching contaminants than others. Spacing out samples over time in a stratified sampling pattern is better at catching risky […]
Decline of diatoms due to ocean acidification: Study shows unexpected negative impact by CO2 on important plankton group
Diatoms are the most important producers of plant biomass in the ocean and help to transport carbon dioxide (CO2) from the atmosphere into the deep ocean and thus regulate our climate. Because diatoms rely on silica rather than calcium carbonate to build their shells, they were previously thought to benefit from ocean acidification — a […]
