Researchers reporting in ACS Central Science have developed color-changing bandages that can sense drug-resistant and drug-sensitive bacteria in wounds and treat them accordingly.
Researchers have identified a protein in foxtail millet that can help stave off atherosclerosis in mice genetically prone to the disease. They report their results in ACS’ Journal of Agricultural and Food Chemistry.
Going “green” with urine carries some potential risks. Now, research published in ACS’ Environmental Science & Technology (ES&T) shows this risk is likely to be minimal.
Researchers reporting in ACS Nano have devised a blood test that quickly and sensitively diagnoses the disease at early stages.
Researchers in Environmental Science & Technology report that a large desalination plant in Australia has the unexpected benefit of attracting some species of fish, increasing their abundance at the discharge site.
Arctic sea-ice is in decline, causing polar bears in the Barents Sea region to alter their feeding and hunting habits. Bears that follow sea-ice to offshore areas have higher pollutant levels than those staying on land — but why? A study in ACS’ Environmental Science & Technology reports the likely reasons.
New research reported in ACS’ Environmental Science & Technology on one of the permitted neonicotinoids indicates it effectively controls pests and might even help bees.
Researchers reporting in ACS Nano have developed a new manufacturing process that could enable ultra-efficient atomic computers that store more data and consume 100 times less power.

Researchers reporting in ACS Nano have developed self-assembling liquid crystal microlenses that can reveal 4D information in one snapshot.
Technologies to mitigate pollution have become widespread in recent years, but scientists are now exploring a new, pared-down approach: using nature to restore ecological balance. They report their findings in ACS’ Environmental Science & Technology.
Researchers reporting in ACS’ Environmental Science & Technology have found that certain perfluoroalkyl substances (PFASs) found in ski wax bioaccumulate and biomagnify in the food chain at a Nordic skiing area.
Researchers reporting in ACS Central Science have developed a catalyst that can transform polyethylene –– the type of plastic used to make grocery bags –– into high-quality liquid products, such as motor oils and waxes.
