Florida International University scientists have, for the first time, detected a toxic tire-derived chemical in Florida waterways and developed a new testing method that makes it easier to find and monitor the pollutant at extremely low levels. The study focuses on 6PPD-quinone (

Since the 1980s, researchers have sought to use laser light to control chemical reactions relevant to photochemistry, catalysis and light-responsive materials. But this technique, known as coherent control, has a blind spot: There has been no way to directly see the molecules in

Scientists from the University of Manchester have shown how a plasma-based approach, using nonthermal plasma—an electrically energized gas often described as the fourth state of matter—can prevent catalyst deactivation in a key hydrogen production reaction, maintaining stable per

Over recent decades, harmful algal blooms have become increasingly common. These blooms often consist of bacteria called "cyanobacteria" in freshwater ecosystems. They can produce debilitating toxins, suffocate marine life by depleting oxygen in the water, and make water unsafe f

Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, these molecules also play an important role in normal cellular signaling. While ROS are established as essential signaling molecules in various organisms, t

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.

Some periods in Earth's history are so different from our own that they may as well belong to another planet. Many people are interested in the age of dinosaurs or the Ice Ages, but it is an intermediate world, the Miocene Epoch—a sort of "in-between" world, geologically speaking

Natural gas still plays an important role in many industrial sectors, but it is a climate-damaging fossil fuel. TU Wien and the University of Innsbruck have now discovered an unexpected reaction pathway that makes it possible to synthesize natural gas, or methane (CH4), using CO2

Fire ants are a common nuisance across much of the United States, known for their painful stings and unsightly dirt mounds in lawns and outdoor spaces. However, for individuals who are allergic, these pests can cause potentially life-threatening reactions. To help keep communitie

After a recent study found New Orleans is at a ‘point of no return’ amid the climate crisis, some locals say they will ‘only leave if forced to’. But what would it take to stay?When a study in May concluded that New Orleans has hit a “point of no return” due to the climate crisis

A decades-old puzzle about water has finally been unraveled. Researchers found that water trapped in tiny nanoscale spaces is not inherently more reactive. Instead, the intense pressures created inside these microscopic gaps explain most of the effect, while the surrounding mater

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
