Coastal and estuarine carbon removal technique may backfire when pushed too far

Scientists investigating a proposed way to remove carbon dioxide from the atmosphere using seawater have found that adding too much alkalinity to neutralize acids can trigger chemical reactions that undermine the process.

Burned-home soils showed uneven lead, arsenic contamination after Los Angeles wildfires

A chemical analysis of residential soils and ash around California homes burned by the Eaton and Palisades wildfires in early 2025 revealed wide variation in contamination by potentially harmful elements, including lead, according to a study published in Environmental Science and

Nanopattern method unlocks precise control of disorder for wave-guiding devices

A research team has developed a methodology to precisely design and control the "degree of disorder" in nanopattern arrays using metal-infiltrated block copolymer (BCP) thin films. The work was led by Professor So Youn Kim of the Seoul National University College of Engineering D

Synthetic chemical framework can switch magnetic spin states at near ambient temperatures

There is growing demand for smart materials that can change their physical properties in response to various external stimuli such as light, heat, pressure, magnetic fields and electric fields. One such physical property is the magnetic state of material complexes, which depends

What science tells us about the algae bloom in the Lincoln Memorial Reflecting Pool

Algal blooms in the Lincoln Memorial Reflecting Pool in Washington, D.C., have long been a visible public nuisance. When the pool turned green again on June 15, less than two weeks after President Donald Trump's US$14 million renovation, it sparked outrage, a rush to use chemical

How PFAS chain length influences environmental fate and water treatment

Per- and polyfluoroalkyl substances (PFAS), often referred to as "forever chemicals," are among the most persistent contaminants found in water systems worldwide. Their strong carbon-fluorine bonds make them highly resistant to degradation, allowing them to remain in the environm

Abundant catalyst converts methane into valuable liquid chemicals

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and their collaborators have demonstrated a promising new approach for converting methane—the primary component of natural gas—into liquid chemicals that are precursors for many industrial chemical

Darwin residents want answers on toxic gas emissions: Science shows their concerns are war

For years, Darwin residents have been concerned about toxic chemicals emitted by the city's two gas export facilities. In fact, some locals are so worried about these airborne chemicals—particularly benzene—they recently formed a community group and launched a fundraiser to buy a

‘Beautiful blobs’: synthetic life a step closer as scientists make cells using lab-made DN

Tiny, quivering spheres designed to feed and multiply raise prospect of artificial organisms to make drugs, food and fuelResearchers claim they are closer to creating life from scratch after building tiny, quivering blobs that use lab-made DNA to feed, grow and multiply in a dish

Single-atom catalyst turns lignin into valuable chemicals with near-complete conversion

Researchers at The University of Manchester and Hebei University of Technology have identified how a new class of catalyst can break down lignin into useful chemical building blocks, offering a more sustainable route to replace fossil-based materials.

Scientists devise new method for tracing environmental PFAS contamination better

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a class of synthetic chemicals widely used in industrial processes and consumer products because of their resistance to heat, water and oil. However, these same properties also make them highly resistant to environmental de

Synchronized infrared lasers control molecular shape changes and expose hidden fingerprint

Researchers from the Molecular Physics and Physical Chemistry departments of the Fritz Haber Institute have shown how two highly synchronized infrared (IR) laser beams can control molecules as they switch between different structural conformations. Their study provides a new wind
