Liquid crystal monomers (LCMs) are critical components of laptop, television and smartphone screens. Given their ubiquity in the environment, these compounds are considered persistent pollutants, posing threats to marine life that scientists want to understand. Research published in ACS’ Environmental Science & Technology provides initial evidence that LCMs from household electronics or electronic waste (e-waste) can accumulate in dolphin and porpoise tissues, including blubber, muscle, and brain, demonstrating their ability to cross the blood-brain barrier.

As cultured meat moves toward commercialization, people want to understand how it impacts health compared to conventional animal meat. So, researchers publishing in ACS’ Journal of Agricultural and Food Chemistry conducted an initial food safety study to identify potential allergens in cultured beef cells. They report mixed hazard results: Cultured cells contained relatively fewer traditional protein allergens than regular steak but provoked stronger immune reactions in blood samples from people with an acquired meat allergy.

To find new ways to shield hair from heat, sunlight and air pollution, researchers in Brazil are turning to vegan-friendly ingredients for shampoos and conditioners. Published in ACS Omega, early tests show that a fruit-algae combination added to haircare products coats strands with a protective film. Although the botanical film makes hair slightly less elastic, it improves shine and makes locks easier to comb compared to hair washed and conditioned with products not containing the biopolymer.

In early 2025, the party-loving city of New Orleans, Louisiana, hosted two major events within the span of a month: Super Bowl LIX and Mardi Gras. And, as with many major events, it appears there was an increase in recreational drug use during this time. Researchers publishing in ACS’ Environmental Science & Technology Letters show how monitoring wastewater revealed an increase in the use of relatively new dangerous synthetic opioids during these two events.
