Geologists have uncovered evidence of when Earth may have first supported an oxygen-rich atmosphere similar to the one we breathe today. The study suggests that upheavals in the earth’s crust initiated a kind of reverse-greenhouse effect 500 million years ago that cooled the world’s oceans, spawned giant plankton blooms, and sent a burst of oxygen into the atmosphere. picked by AutumnLotus 2 years ago 4 comments edit related share science |

Jülich scientists have made an important step on the long road to artificially imitating photosynthesis. They were able to synthesise a stable inorganic metal oxide cluster, which enables the fast and effective oxidation of water to oxygen. picked by AutumnLotus 2 years ago 0 comments edit related share science |

Human civilisation might have been millions of years more advanced today had it not been for massive chains of undersea volcanoes that erupted billions of years ago. New research has found that the birth of the oxygen-rich atmosphere we breathe was delayed 200 million years by marine volcanoes that destroyed the vital gas almost as fast as it was being exhaled by early bacteria. picked by AutumnLotus 2 years ago 3 comments edit related share science |

Nanotechnology has paved the way for a healthy cigarette -- one whose filter can absorb every impurity and release small doses of oxygen to the smoker, which doctors say will keep the smoker alive on average 5-10 years longer than a non-smoker.

Plants and flowers are the lifeblood of the Earth, providing oxygen for animals and humans alike. However, not everyone is fortunate enough to have a space to plant a garden. New Yorkers and other city dwellers haven’t let that stop them. These are some of the world’s most beautiful rooftop gardens, ranging in various size, shape, color and lifeforms. picked by shuallyo 3 months ago 3 comments edit related share weird |

Scientists analysing data gathered by the Cassini spacecraft have confirmed the presence of heavy negative ions in the upper regions of Titan’s atmosphere. These particles may act as organic building blocks for even more complicated molecules and their discovery was completely unexpected because of the chemical composition of the atmosphere (which lacks oxygen and mainly consists of nitrogen... read full post picked by AutumnLotus 2 years ago 1 comments edit related share plime.com |
In pasteurizing, juice is heated and stripped of oxygen. Then it's put in huge storage tanks where it can be kept for upwards of a year. It gets stripped of flavor-providing chemicals, which are volatile. When it's ready for packaging, companies such as Tropicana hire flavor companies such as Firmenich to engineer flavor packs to make it taste fresh. People think not-from-concentrate is a fresher ... read full post picked by 2manyusernames 9 months ago 12 comments edit related share plime.com |
Researchers at the Stanford University School of Medicine have uncovered the first clues about the ancient origins of a mother's intricate lifeline to her unborn baby, the placenta, which delivers oxygen and nutrients critical to the baby's health. The evidence suggests the placenta of humans and other mammals evolved from the much simpler tissue that attached to the inside of eggshells. picked by AutumnLotus 2 years ago 2 comments edit related share science |
A spectacular new image shows how complex a star's afterlife can be. By studying the details of this image made from a long observation by NASA's Chandra X-ray Observatory, astronomers can better understand how some stars die and disperse elements like oxygen into the next generation of stars and planets.
