What"s stopping US climate policies from working effectively?
In an effort to reduce greenhouse gas emissions and curb global warming, the U.S. has enacted several ambitious federal laws, such as the Inflation Reduction Act (IRA) passed in 2022 and the Infrastructure Investment and Jobs Act (IIJA) of 2021......»»
A path to achieve a net-zero greenhouse gas economy
Anew report co-authored by 68 scientists from more than a dozen institutions—including the University of Pennsylvania—offers a first-of-its-kind high-resolution assessment of carbon dioxide (CO2) removal (CDR) in the United States......»»
Team upgrades technology for monitoring methane emissions
Researchers at the National Institute of Standards and Technology (NIST) have upgraded a highly precise technology designed to monitor emissions of methane, a critical greenhouse gas, and other trace gases, even in harsh field conditions. Measuring m.....»»
Going beyond plastic: Tara gum as a green polymer
Synthetic, non-biodegradable plastics are major sources of environmental pollution and have prompted rising interest in sustainable, biodegradable alternatives derived from natural polymers. "Tara gum," derived from the seeds of the tara tree (Caesal.....»»
U.S. Emissions Fell by 2 Percent in 2023, Even as Economy Grew

Candida evolution disclosed: New insights into fungal infections
Global fungal infections, which affect 1 billion people and cause 1.5 million deaths each year, are on the rise due to the increasing number of medical treatments that heighten vulnerability. Patients undergoing chemotherapy or immunosuppressive trea.....»»
Review covers optical aspects of quantitative photoacoustic tomography
Quantitative photoacoustic tomography (QPAT) is a medical imaging technique that combines laser-induced photoacoustic signals and ultrasound detection to create detailed three-dimensional images of biological tissues. The process involves irradiating.....»»
Mating anchovies stir up the sea as much as a major storm—and it"s good for the environment, too
Why would oceanographers ever care about anchovies having sex? We do because these small fish can help mix different layers of the ocean when they mate. This circulates nutrients, oxygen, and greenhouse gases around different layers of the ocean, the.....»»
Carbon pollution is down in the US, but not fast enough to meet Biden"s 2030 goal, new report says
Climate-altering pollution from greenhouse gases declined by nearly 2% in the United States in 2023, even as the economy expanded at a faster clip, a new report finds......»»
Why we need to know more about individual carbon footprints
Most countries, including Switzerland, record their greenhouse gas emissions by source and sector. In absolute terms, Swiss greenhouse gases make up less than 1% of global emissions. With an average of 12 metric tons of CO2 equivalents per capita per.....»»
The ViXion01 could be a useful wearable for people struggling to focus their eyes
A lot of us with non-impaired vision probably take for granted that we have relatively no issues with seeing things. However, there are many things that can affect eyesight. This includes medical issues or simply by getting older. For those who might.....»»
