Because they are used in everything from cosmetics to dental floss to nonstick pans, per- and polyfluoroalkyl substances (PFAS) are frustratingly abundant in our environment, including in our food, rain, and drinking water. They're persistent, too, earning their nickname "forever chemicals," and have been linked to health effects ranging from cancers to liver toxicity to reduced fertility.

Florida is among the wettest U.S. states, but that doesn't mean it is drought-free. Nearly all of Florida faced at least "moderate" drought, and nearly 80 percent faced "extreme" conditions in April 2026, according to data from the U.S. Drought Monitor. Unusually dry conditions gripped the state for much of 2025, but the intensity and extent of the drought ratcheted up starting in January 2026.

Every year, the World Meteorological Organization, or WMO, tracks a set of key climate indicators--including the amount of carbon dioxide in the atmosphere and the Earth's temperature--to assess how global warming is progressing. In their latest report, released last Sunday, the authors decided to include a new measure: the Earth's energy imbalance. "Climate change is often discussed in...

Most people spend a lot of time and effort making their presentation engaging and impactful, but how much time do you spend making sure it is accessible!? An accessible presentation takes into account the diverse backgrounds and abilities of the audience, to support a better understanding of the message and information you are trying to share. This is particularly important for scientific research, where presenters need to be confident that their research is being communicated in a manner that is both scientifically sound and accessible; regardless of the barriers that will naturally exist, be they language, cultural or a disability.

n mid February I was invited by my colleague Dr. Win McLaughlin to give a talk at Southwestern Oregon Community College (SWOCC) which has a pretty fantastic science program. Win flew me up for the presentation and a couple of days of fieldwork during a rare dry spell on the perpetually rainy Oregon coast. I had not visited in over a decade, and was thrilled at the opportunity! Here is a bit of a slideshow from my trip.

The Lunar Targeting Plan is the Artemis II crew's Moon observing assignment. It is fine-tuned to the exact lighting conditions on the Moon's surface when the Artemis II crew flies by, and for their viewing angle as they're hurtling through space. Like a spacewalk plan, it provides strong, detailed guidance, plus flexibility for the crew to make decisions based on what they're seeing and experiencing in real time. Targets are prioritized based on both their science value and their visibility at the time of observation.
