New, safer waterproof coating invented by MIT scientists
Traditional waterproofing compounds, long-chain polymers, accumulate and persist in the environment and the human body, posing health concerns. Environmental regulators are expected to soon ban the use of the polymers.
Making safer, more powerful lithium-ion batteries requires right recipe
A team from Purdue University has published research that examines the relationship between the active and inactive elements of lithium-ion batteries, and how the micro- and nano-structure of their respective ingredients reflects on the performance and safety of the batteries.
Safer to ride in yellow taxis
A recent study led by researchers from the National University of Singapore (NUS) has found an explicit link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility of yellow makes it easier for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate, reported.
Smartwatch app could help make nursing homes safer
To prevent nursing home residents from falling or otherwise injuring themselves, an alert system involving lights, alarms and call buttons lets certified nursing assistants, or CNAs, know a resident needs assistance.
BPA replacement in plastics not safer
The bisphenol A (BPA)-free trend started after studies found a link between BPA and health issues such as early puberty and prostate cancers. After that, products with bisphenol S (BPS) started cropping up as a safer alternative. But now a UCLA-led study suggests that BPS can be just as harmful as BPA, causing faster embryonic development and disruption of the reproductive system in animals.
