We envision a world in which trust between scientists and the public forms the basis for a more sustainable and resilient environment for all people to live, grow, and prosper.
Scientists Find the First Ice Core From the European Alps That Dates Back to the Last Ice Age
The new study, published in the June issue of PNAS Nexus, examines a 40-meter long ice core from Mont Blanc’s Dôme du Goûter. Using radiocarbon dating techniques, the research team found that the glacier provides an intact record of aerosols and climate dating back at least 12,000 years. Aerosols are small droplets and particles in the air such as desert dust, sea salts, sulfur from volcanic eruptions, soot from forest fires, as well as pollutants and other emissions from human activities.
A New, Detailed Analysis of the Benefits and Trade-offs of Urban Street Trees in Las Vegas
Earth is hotter than it has been in 125,000 years, scientists say, and Las Vegas continues to break temperature records. Planting and preserving the city’s street trees is one method that brings many benefits, from the cool air of their shade to their ability to store carbon. Now, a new study takes a deeper look at just how much trees can offer Sin City, as well as the water tradeoffs inherent in growing trees in a desert.
Desert Lichen Offers New Evidence for the Possibility of Life on Other Planets
The question of whether Earth is alone in harboring life has captivated humanity for millennia. In recent years, scientists have turned to Earth-like planets in other solar systems that may show the most promise, but many revolve around stars that emit much stronger solar radiation than our own. Now, a new study offers evidence that life as we know it may be able to thrive on those Earth-like exoplanets.
