Hundreds of plants, fungi, and animals can do it. Now scientists think bioluminescence may have evolved 540 million years ago in Earth’s ancient oceans.
Eventually, something worked, though no one was really sure what it was that did the trick. Or even if the flare just subsided on its own. Leaving the hospital, I was instructed to slowly wean myself off of the steroids. I followed their directions, but each time I tried to taper off...
When did man appear on Earth? The first human ancestors appearedbetween five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs. They were flaking crude stone tools by 2.5 million years ago. ...
Cyanobacteria are not the only phototrophs that primarily use visible light as energy source. Plants, algae, and other chlorophototrophic bacteria are all potential competitors for visible light. Because of the intense competition for light, some terrestrial cyanobacteria have evolved a specific mechanis...
While I was defiantly looking forward to this film, I did go into the theater with some trepidation. I did look at a few reviews before seeing it, and while there were many positive reviews for the movie, there were quite a few people who were quite disappointed in it. Some went as ...
The question that has not been resolved, however, is: Did the production of oxygen coincide with the GOE, or did living organisms have access to oxygen even before that event? One side of this debate states that molecular oxygen would not have been available before ...
One bayou meanders toward downtown Houston. The other runs in parallel to the south, much of it through a concrete channel.

sessile life form, plants have evolved various mechanisms to perceive and respond to their neighbors [9,10]. One of these processes is chemical messaging, nowadays called plant–plant communication, which plays an important role in plants’ coexistence. Plants release volatile organic compounds (VOCs...
