Scientists speculate that if life were to have spontaneously developed on Earth, the first thing there would need to be are vesicles.
- The findings also suggest that life may have formed in the deep oceans of other celestial bodies in our solar system as well.
- These are a lot like cell membranes, only they don't contain any of the complicated machinery that real, living cells do.
- Researchers recently demonstrated that these vesicles form frequently in environments similar to the hydrothermal vents of early Earth.

The net famously failed to work as planned last year. Now, a new version is making waves.
- A new version of the netting used to clean up the Great Pacific Garbage Patch has passed trials.
- The previous versions of the device didn't work very well, and broke before their missions were finished.
- A fleet of these devices are in the works. They could cut the size of the Great Pacific Garbage Patch in half within five years of work.
Bio-plastics could prove to be a suitable alternative to single-use plastics.
- The flexible bio-plastic, called MarinaTex, breaks down within about four to six weeks.
- One Atlantic cod contains enough waste to produce hundreds of MarinaTex bags.
- More than half of single-use plastics end up in the world's oceans.
Humpbacks swap songs at remote group of islands in the South Pacific.
- A whale's song reflects its geographical and social history.
- A new study identifies for the first time a major migratory crossroads where whales meet.
- The discovery sheds light on the mystery of how whale songs evolve across the Pacific.
