From the RMS Titanic to the SS Endurance, shipwrecks offer valuable — yet swiftly deteriorating — windows into the past. Conservators slowly dry marine wooden artifacts to preserve them but doing so can inflict damage. To better care for delicate marine artifacts, researchers in ACS Sustainable Chemistry & Engineering developed a new hydrogel that quickly neutralizes harmful acids and stabilized waterlogged wood from an 800-year-old shipwreck.

A group of young students became bonafide biomedical scientists before they even started high school. Through a partnership with a nearby university, the middle schoolers collected and analyzed environmental samples to find new antibiotic candidates. One unique sample, goose poop collected at a local park, had a bacterium that showed antibiotic activity and contained a novel compound that slowed the growth of human melanoma and ovarian cancer cells in lab tests.

Not all plastics are equal — some types and colors are easier to recycle than others. For instance, black foam and black coffee lids, which are often made of polystyrene, usually end up in landfills because color additives lead to ineffective sorting. Now, researchers report in ACS Central Science the ability to leverage one additive in black plastics, with the help of sunlight or white LEDs, to convert black and colored polystyrene waste into reusable starting materials.

Asking children “What does a scientist look like?” now results in more illustrations of women and people of color than decades ago. But do generative artificial intelligence (AI) tools also depict the diversity among scientists? Researchers reporting in the Journal of Chemical Education prompted AI image generators for portraits of chemists. They found that none of the collections accurately represents the gender, racial or disability diversity among real chemists today.
