In any conventional silicon-based solar cell, there is an absolute limit on overall efficiency, based partly on the fact that each photon of light can only knock loose a single electron, even if that photon carried twice the energy needed to do so.

The Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) recently received federal approval to proceed with preliminary design work for a state-of-the-art building that would revolutionize investigations into how interactions among microbes, water, soil, and plants shape entire ecosystems.

New findings show that old-growth forests, a critical nesting habitat for threatened northern spotted owls, are less likely to experience high-severity fire than young-growth forests during wildfires. 

The heat wave that scorched Europe last week felt like a red alert of climate change. 

New evidence suggests that high-energy particles from space known as galactic cosmic rays affect the Earth's climate by increasing cloud cover, causing an "umbrella effect".

The Global Precipitation Measurement mission or GPM core satellite passed over the storm and measured the rate in which rain was falling throughout it.

The medical costs of uncontrolled asthma, combined with productivity losses due to sick days, could cost the U.S. economy more than $963 billion over the next 20 years.

Bring on the storm.

Ecosystems in North America’s Great Plains have shifted hundreds of miles northward in the past 50 years, driven by climate change, wildfire suppression, energy development, land use changes, and urbanization, according to a recent study published in the journal Nature Climate Change.

When forecasting weather, meteorologists use a number of models and data sources to track shapes and movements of clouds that could indicate severe storms.
