A new study from scientists at Purdue University reports that far-red radiation, in combination with increased carbon dioxide (CO₂) concentration, significantly enhances biomass production in young leaf lettuce grown under controlled environments, offering practical guidance for

The effects of individual climate factors on ecosystems are usually considered in isolation. However, in reality, they occur simultaneously and influence each other. Increasing CO2 concentrations in the atmosphere contribute to climate warming, which in turn fosters more frequent

New research has found young birds living near contaminated industrial and military sites in suburban Melbourne carry especially high concentrations of PFAS, so-called "forever chemicals."

Manganese is an essential trace element. However, in excessive concentrations, the metal can cause health problems. Two Eawag researchers have now produced a global risk map for manganese in groundwater. Half of the world's population uses groundwater as drinking water. According

A new Southwest Research Institute-led study proposes a solution to a longstanding puzzle in planetary science: What caused the concentration, assembly, and preservation of millimeter-sized, spherical mineral grains within the parent bodies of the most common meteorites? The work

Concentrations of gas were continuously raised in Europe during June hot spell, with potentially deadly effectsWidespread air pollution was a feature of June’s record-breaking heat across western Europe and is likely to increase again as the UK experiences its third heatwave of t

Stars like our sun are formed from the collapse of stellar objects called prestellar cores, cold and dense concentrations of gas and dust held together by gravity. While many questions remain about the exact mechanisms of star formation, advanced radio telescopes have given resea

Portable screen-printed carbon electrode (SPCE) biosensors offer a rapid, low-cost way to detect microcystin-lysine-arginine (MC-LR), an extremely potent toxin produced by cyanobacteria during harmful algal blooms in freshwater. Even at low concentrations, MC-LR can damage the li

Methane (CH4) is a potent greenhouse gas whose concentration in the atmosphere has risen sharply in recent decades. Wetlands are the largest natural source of methane to the atmosphere, but large uncertainties remain about how much methane comes from wetlands and how these emissi

In an innovative gas fermentation process, reducing the concentration of carbon dioxide was found to significantly improve microbial production of the biodegradable plastic poly[(R)-3-hydroxybutyrate]. Researchers found that hydrogen-oxidizing bacteria grown under safe, nonflamma

A new Aotearoa New Zealand study has found that nitrate concentrations in drinking water are associated with an increased risk of preterm birth, even at levels well below the current drinking water standard. The study, published in Environmental Research, analyzed 735,831 singlet

AI companies want to capture the value created by entire industries. That concentration of wealth and power is society’s greatest riskOpposition to AI datacenters has emerged as a primary theme in US politics, one that – surprisingly – doesn’t fall along party lines. We applaud people coming together for constructive debate on any issue, and agree that communities need to evaluate whether any economic benefits these datacenters bring is worth their costs. Still, we worry that a focus o
