In 2021, we unveiled our most ambitious sustainability goals ever. These goals include a 50% reduction in carbon emissions by 2030, as indexed to revenue over a 2019 baseline.
In 2022, we announced that renewable sources provided over 20% of our global electricity usage.
This year, Promega is excited to announce that we’re committing to 100% renewable electricity by 2025.

HBO’s The Last of Us has successfully brought fungal pathogens to the forefront of the pandemic discourse, raising questions as to whether a fungus could really pose a significant threat to humans. While scientists agree that the fungus featured in the show, cordyceps, won’t be making the required inter-species jump any time soon, there is a fungal pathogen that has been taking root in hospitals across the U.S. which gives some cause for concern: Candida auris.

These so-called “forever chemicals”, or per- and polyfluoroalkyl substances (PFAS), are a family of organic compounds where fluoride replaces hydrogens atoms on carbon chains. They are very water and oil repellent, which makes them ideal for use in non-stick cookware, stain-proof fabrics and fire-suppressing foams. Recent studies, however, show that exposure to PFAS is linked to a range of health issues—from increased cholesterol levels to some cancers. Even levels of PFAS present in drinking water in as low as parts per billion levels can pose risks to human health. These risks are exacerbated by the tendency for PFAS to bioaccumulate, or become concentrated in the tissues of humans and animals.
Methods do exist to filter out PFAS from water. But what do you do when it’s time to replace those filters? Simply throwing out PFAS-contaminated equipment just moves the problem to a landfill.
Instead, these “forever chemicals” need to be destroyed. Most existing strategies for breaking down PFAS use harsh conditions, such as incinerating PFAS residues in furnaces or oxidizing them in supercritical water—water that is at more than 37°C and 200atm of pressure. Now, scientists reporting in Science have discovered that such extreme methods may not be needed to destroy “forever chemicals” (1).

This globally recognized day was designated by the North American Nature Photography Association (NANPA) to embrace the value of nature and encourage the enjoyment of nature photography.
Photography helps us explore the natural world and advance conservation efforts to protect plants, nature, and wildlife both locally and globally. One of the great things about Nature Photography Day is that you can participate wherever you are, with whatever equipment you have—nature is all around us!
