The sea surface covered by seaweed is now as big as South America
The first global mapping of macroalgae blooms in the ocean, last year, reveals rapid growth and a new record for the area seaweed blankets.

Making yards more diverse can reap big environmental benefits
Replacing grass with native plants uses less water and fewer chemicals while providing additional benefits to people and wildlife.
- Chemistry
Scientists Say: Rubisco
Rubisco is a key protein in the process of photosynthesis, which feeds plants — and, in turn, us.

No sun? No prob! A new process might soon grow plants in the dark
Teamwork makes green-work! Collaborating scientists came up with an electrifying farming trick that could make sunlight optional.

Ponds made to control floods can spew climate-warming gases, study finds
Younger stormwater ponds can release more carbon in gases than they absorb, a study finds. That could aggravate global warming.
- Chemistry
Scientists Say: Decay
This word can refer to rotting flesh or the transformation of radioactive atoms.

Recycling a climate-warming gas could make ‘greener’ farmed fish
Instead of warming the climate, methane gas can be collected to help farmers. Along the way, it may also save some fish.
- Life
In blazing heat, some plants open leaf pores — and risk death
When heat waves and droughts collide, water is precious. Some thirsty plants try to cool off by opening tiny pores — only to lose water even faster.

A bubble of air lets some lizards breathe underwater
Anolis lizards leap into streams to escape danger. Now researchers have figured out how they can stay underwater for up to a quarter of an hour.

Sudden shark die-off 19 million years ago eliminated most species
New fossil evidence shows 90 percent of sharks died in the mysterious event.
