A University of Melbourne led study has established how plants use their metabolism to tell time and know when to grow - a discovery that could help leverage growing crops in different environments, including different seasons, different latitudes or even in artificial environments and vertical gardens.

The ocean floor is vast and varied, making up more than 70% of the Earth’s surface. Scientists have long used information from sediments at the bottom of the ocean — layers of rock and microbial muck — to reconstruct the conditions in oceans of the past.

Spring snowmelt in the Alps is occurring earlier in the year due to climate change and as a result triggering abrupt deviations in mountain ecosystems. 

As the frequency and size of wildfires continues to increase worldwide, new research from Carnegie Mellon University scientists shows how the chemical aging of the particles emitted by these fires can lead to more extensive cloud formation and intense storm development in the atmosphere. 

Marine protected areas (MPAs) around Oʻahu do not adequately protect populations of herbivorous reef fishes that eat algae on coral reefs.

In tropical oceans, a combination of sunlight and weak winds drives up surface temperatures in the afternoon, increasing atmospheric turbulence, unprecedented new observational data collected by an Oregon State University researcher shows.

As the planet warms, scientists expect that mountain snowpack should melt progressively earlier in the year.

The regulatory agency in charge of managing the Delaware River and its tributaries voted last week to permanently ban natural gas drilling and fracking within the entire four-state watershed, which supplies the drinking water for more than 13 million people in Pennsylvania, Delaware, New Jersey, and New York.

NASA researchers have found a small but unexpected decrease in air pollution over some parts of Africa despite growing use of fossil fuels in many countries due to development and economic growth.

Their report, authored by 38 Australian, UK and US scientists from universities and government agencies, is published today in the international journal Global Change Biology.
