Hydrogen, a promising fuel, has extensive applications in many sectors. However, its safe and widespread use necessitates reliable sensing methods. While tunable diode laser absorption spectroscopy (TDLAS) has proved to be an effective gas sensing method, detecting hydrogen using TDLAS is difficult due to its weak light absorption property in...

Bacteria breakthrough could accelerate mosquito control schemes
Mosquito larvae grow faster if they're exposed to particular bacteria, according to a new study that could help global health programs.
Drought Expands Across the U.S.
Unusually dry conditions gripped over half the contiguous United States in October 2024.
Microplastics Increasing in Freshwater, Directly Related to Plastic Production
Microplastics have been steadily increasing in freshwater environments for decades and are directly tied to rising global plastic production since the 1950s, according to a new study by an interdisciplinary team of Penn State researchers.
Fueling Greener Aviation With Hydrogen
Despite ongoing efforts to curb CO2 emissions with electric and hybrid vehicles, other forms of transportation remain significant contributors of greenhouse gases.
Scientists tackle farm nutrient pollution with sustainable, affordable designer biochar pellets
What if farmers could not only prevent excess phosphorus from polluting downstream waterways, but also recycle that nutrient as a slow-release fertilizer, all without spending a lot of money? Researchers now show it's possible and economical.
New trigger proposed for record-smashing 2022 Tonga eruption
Fifteen minutes before the massive January 2022 eruption of the Hunga Tonga-Hunga Ha'apai volcano, a seismic wave was recorded by two distant seismic stations. The researchers propose that the seismic wave was caused by a fracture in a weak area of oceanic crust beneath the volcano's caldera wall. That fracture...
Satellite imagery may help protect coastal forests from climate change
A new study details how climate change transforms coastal wetlands in North Carolina from forest to marshland or even open water, and how satellite imagery may help better direct conservation efforts to preserve those areas.
Small Modular Nuclear Reactors can Help Meet US Energy and Emission Goals – If we Let Them
Interest in small modular nuclear reactors, or SMRs, is skyrocketing with tech companies including Google, Amazon and Microsoft investing in the emerging low-carbon energy technology.
Exposure to Certain Pollution Sources Harms Children’s Learning and Memory, USC Study Shows
A new USC study involving 8,500 children from across the country has revealed that a form of air pollution, largely the product of agricultural emissions, is linked to poor learning and memory performance in 9- and 10-year-olds.
