The Environmental Protection Agency says it will propose a drinking water limit for perchlorate, a chemical in certain explosives and propellants.Continue Reading
Many organizations are taking actions to shrink their carbon footprint, such as purchasing electricity from renewable sources or reducing air travel. Both actions would cut greenhouse gas emissions, but which offers greater societal benefits? In a first step toward answering that question, MIT researchers found that even if each activityContinue Reading

A meltwater lake that formed in the mid-1990s on Greenland’s 79°N Glacier has been draining in sudden, dramatic bursts through cracks and vertical ice shafts. These events have accelerated in recent years, creating strange triangular fracture patterns and flooding the glacier’s base with water in just hours. Some drainages evenContinue Reading
Limiting use of desflurane helps hospitals reduce their greenhouse gas emissions; the European Union now prohibits its use during most procedures. By Phil McKenna Desflurane is a common anesthetic used in hospital operating rooms worldwide. It’s also a climate super pollutant. Now, several decades after the drug was first introduced,Continue Reading
By Michael Allen For the first time, scientists have used NASA’s IXPE (Imaging X-ray Polarization Explorer) to study a white dwarf star. Using IXPE’s unique X-ray polarization capability, astronomers examined a star called the intermediate polar EX Hydrae, unlocking the geometry of energetic binary systems. In 2024, IXPE spent nearly one weekContinue Reading
