The recovery of the ozone layer in Earth's stratosphere could be delayed by several years, according to an international study led by Swiss research institution Empa which included contributions from University of Bristol researchers. The cause is persistent emissions of so-called feedstock chemicals, which are still permitted as raw materials in industry. These ozone-depleting substances have so far been excluded from international agreements because, according to the current study, their emissions and use have been significantly underestimated.
Can listening to forests help us understand if the life inside them is thriving? Apparently, yes. Giacomo Delgado likens it to a doctor examining heart health. “A doctor has listened to many people’s hearts, and knows what healthy hearts sound like,” Delgado, a doctoral researcher in the Department of Environmental Systems Science at ETH Zürich, […]
Egg freezing is becoming increasingly popular, yet most people who freeze their eggs never return to use them. When imposed storage limits are reached, individuals must choose whether to discard unused eggs, donate them to others for reproductive use, or donate them to research; although many say their preference is to donate to research, actual donations remain rare, leaving a valuable resource largely unused for scientific progress.
The ozone layer has been on track to recover thanks to the Montreal Protocol—but a loophole may be holding it back. Chemicals still permitted for industrial use are leaking into the atmosphere at higher rates than expected. Scientists now estimate this could delay ozone recovery by up to seven years. Closing this gap could speed up healing and reduce harmful UV exposure worldwide.
Often hailed as the most successful international environmental agreement of all time, the 1987 Montreal Protocol continues to successfully phase out the global production of chemicals that were creating a growing hole in the ozone layer, causing skin cancer and other adverse health effects.

4 things to know about the weather: Records likely Thursday, Saturday A bit cooler Friday Chilly, rainy Sunday Some 30s Tuesday morning All three of our major airports set new record highs Wednesday and are expected to do so again Thursday and maybe Saturday too. Skies will be a bit more cloudy Thursday and there will be a small chance for a passing shower or two from late Thursday evening until early Friday morning. Southwest winds Thursday will become northwest on Friday and that will help to hold temperatures down somewhat. Friday will be only about 15° above average whereas Thursday will be more like 25° above average. Saturday will be a bit more tricky of a temperature forecast as the wind turns back to the south and southeast ahead of a strong cold front that will arrive first thing Sunday morning. The D.C. metro area and much of the I-95 corridor are likely to be near 90° Saturday while a Bay breeze could keep Annapolis and much of the Western Shore
NEW YORK (AP) — The aspirations cut a wide swath through American history since 1776 — from the “All men are created equal” of the Declaration of Independence and the “We the people” of the Constitution, to the “indivisible, with liberty and justice for all” of the Pledge of Allegiance. One can find it in […]
The family of a Prince George’s County girl is pleading for the public’s help to find 16-year-old Jamiya Dority, who has been missing more than 10 days. Jamiya was last seen April 4 in Suitland, Maryland. County police say she is considered a critical missing person. Her loved ones are desperate to bring her home. “She has a bubbly, outgoing personality; she loves to do hair,” her mother, Johniece Coleman, said. “She loves to TikTok,” her mom said. Videos shared by her family show Jamiya’s joyful spirit on display, showing her passion for dancing, hair and spending time with her loved ones. Her disappearance has been hard on those who know and love her. “It’s just like the house is empty and stuff,” her sister, Mariya Dority, said. Coleman says her 16-year-old daughter’s presence is missed. “We miss her energy at home,” Coleman said. “She’s very outgoing. We miss her energy.” Prince George’s County police say Jamiya,
The civil case, initially led by the U.S. federal government, accused Live Nation of using its reach to smother competition. A lawyer for the states called it a “great day for antitrust law.”
We are going to see rain and storm chances again for Thursday, with better chances of strong to severe storms on Saturday with a strong cold front.
Before the United States was founded, the idea of volunteering was well underway in the colonies. Now, Americans consistently donate more of their time than citizens of any other country. Judy Woodruff explores how the idea took root and why it's become a part of our national identity. It's part of her series, America at a Crossroads.
