A research group has developed a new and highly efficient upconversion luminescence mechanism by scanning tunneling microscopy (STM) induced luminescence to observe an extraordinarily bright single-molecule upconversion electroluminescence (UCEL) phe.....»»
Satellite data shows how drought changes wildfire recovery in the West
A new study using NASA satellite data reveals how drought affects the recovery of western ecosystems from fire, a result that could provide meaningful information for conservation efforts......»»
Additional nutrients intensify dead zones in oceans, researchers find
As more and more nutrients from land and air enter the world's oceans, the dead zones without oxygen in the water will increase in size and intensity. That is the warning that Ph.D. student Zoë van Kemenade, an organic geochemist at NIOZ, draws from.....»»
New study reveals unintended consequences of fire suppression
The escalation of extreme wildfires globally has prompted a critical examination of wildfire management strategies. A new study from the University of Montana reveals how fire suppression ensures that wildfires will burn under extreme conditions at h.....»»
Research reveals global wildfire risk trends in wildland–urban interface areas
Wildfires present complex socio-economic and ecological challenges, as they devastate vegetation, endanger communities, and cause extensive environmental, wildlife, and human health impacts. These consequences include severe air pollution and soaring.....»»
CERN measures coupled resonance structure that may cause particle loss in accelerators for the first time
Whether in listening to music or pushing a swing in the playground, we are all familiar with resonances and how they amplify an effect—a sound or a movement, for example. However, in high-intensity circular particle accelerators, resonances can be.....»»
Unlocking the climate secrets of North China with ancient tree rings
