The Arctic Ocean has been warming since the beginning of the 20th century, fueled by a process known as Atlantification, according to a new study published Wednesday in the journal Science Advances.

As science looks for better ways to harness electricity from the sun, an explanation for the efficiency of one promising material -- perovskites -- has proven elusive. It’s finding could help speed green energy research.

Every fall, ISO New England, the non-profit organization tasked with overseeing the region’s power grid and transmission lines, assesses the threats posed by the coming winter. This year, they’re worried about Maine.

As the Earth warms with climate change, plants and animals are being forced to move to friendlier conditions. Animals can swim, scamper and fly, but plants are rooted in place -- they rely on seed dispersal to migrate.

Scientists have identified a new type of contagious blood cancer capable of infecting multiple clam species.

According to energy experts, the challenges posed by climate change warrant a greener, smarter, decentralized electrical grid -- a grid better able to accommodate a diversity of renewable energy sources.

To go green -- to build a carbon-neutral economy and achieve net-zero emissions -- the United States will need a lot more rare-earth elements, and recycling could be the way to do it, experts say.

In an effort to bring down costs, General Motors, Tesla, Nissan and other automakers have pledged to start building cars with cobalt-free lithium ion batteries.

Last year, Maine lawmakers instituted a phased ban on all PFAS-containing products, with a total phase out by 2030. Now, Maine is the first state in the U.S. to ban use of biosolids containing PFAS for land treatment.

If the Maine Space Corp. is successful at capturing a slice of the space economy -- expected to be worth $1.5 trillion by 2040 -- maybe science and space students won’t look outside the state, officials say.
