Bisphenol A (BPA) is being removed from many consumer products because of concerns about the chemical’s potential to disrupt the endocrine system. A chemical analog known as bisphenol S (BPS) has been adopted as an alternative in products such as water and baby bottles, thermal paper, and linings of metal cans. In this issue of EHP, a new study shows that BPS has nearly identical impacts on the...

The aluminium ring pulls associated with the latest designs of drinks cans can be relatively easily detached from their mounting on the top of the can and subsequently aspirated. Their small size predisposes them to lodge as foreign bodies (FBs) in the throat. The similarity of atomic number between soft tissue (7.5) and aluminium (13) makes detection of these FBs difficult on soft tissue radio...

A system for analysing can lids is presented Im ages of the can lids are captured by a CCD camera The images are then analysed to determined whether the cans are with or without imprinted text on the lid The system is also capable of detecting whether the can is viewed from the top or the bottom The performance of the system is promising yet there are possibilities

Polyketides and nonribosomal peptides are two important types of natural products that are produced by many species of bacteria and fungi but are exceedingly rare in metazoans. Here, we elucidate the structure of a hybrid polyketide-nonribosomal peptide from Caenorhabditis elegans that is produced in the canal-associated neurons (CANs) and promotes survival during starvation-induced larval arre...
