Unseen Armies Of Viruses And Bacteria Battle In The Deep
2014-05-02 03:58:44

National Science Foundation More than a mile beneath the ocean's surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war. Like pirates boarding a treasure-laden ship, the viruses infect bacterial cells to get the loot: tiny globules of elemental sulfur stored inside the bacterial cells. Instead of absconding with their prize, the viruses force the bacteria to burn their valuable sulfur...

April Flowers for redOrbit.com - Your Universe Online During the Northern Hemisphere's growing season, data returned from satellite sensors shows that the Midwest has more photosynthetic activity than any other region of the planet, according to a recent NASA report. School children are taught that plants convert light to energy through the process of photosynthesis. What is less known, however, is that chlorophyll also emits a fraction of the absorbed light as fluorescent glow, which...

Looking To Geology To Find Answers Of How Life On Earth Originated
2014-03-13 10:20:59

[ Watch the Video: The Origins of Life on Earth ] Brett Smith for redOrbit.com - Your Universe Online By simulating a geologic precursor of cell metabolism, a team of British and American scientists have taken an important step toward understanding how life arose on Earth. Their work is published in a new paper in the journal Astrobiology. “What we are trying to do is to bridge the gap between the geological processes of the early Earth and the emergence of biological life on this...

Living Stone Plant Employs New Way To Improve Underground Photosynthesis
2013-10-24 08:33:07

Public Library of Science A unique plant that lives underground uses multiple mechanisms to boost photosynthesis and offers new insights into how plants adapt to extreme conditions, according to new research published October 23 in the open-access journal PLOS ONE, by Katie Field and colleagues at the University of Sheffield and other institutions. Lithops are a type of South African "living stone," a mostly underground plant that lives in extremely dry conditions. This underground life...

Researchers Demonstrate Effective Recycling Of Radicals During Isoprene Degradation
2013-10-07 07:02:51

Forschungszentrum Juelich Hydroxyl (OH) radicals – known as the detergent of the atmosphere – decompose isoprene in the air. This leads to the creation of new OH radicals, which are then able to purify the air of other pollutants and trace gases. The scientific community had previously only been able to speculate about this mechanism. The atmosphere has an astonishing ability to cleanse itself. Chemical processes ensure that trace gases and pollutants are removed from the atmosphere...

Work on Criegee intermediate published in Science magazine Researchers at Sandia National Laboratories' Combustion Research Facility, the University of Manchester, Bristol University, University of Southampton and Hong Kong Polytechnic have successfully measured reaction rates of a second Criegee intermediate, CH3CHOO, and proven that the reactivity of the atmospheric chemical depends strongly on which way the molecule is twisted. The measurements will provide further insight into...

First Evidence Of Life Deep Under Oceanic Crust Realized
2013-03-15 12:56:53

Lee Rannals for redOrbit.com — Your Universe Online Scientists writing in the journal Science say they have found the first direct evidence of life in the deeply buried oceanic crust. Researchers on board the Integrated Ocean Drilling Program's (IODP) research vessel JOIDES Resolution drilled a water depth of 1.5 miles and hundreds of feet of sediment into the oceanic crust off the west coast of North America. After examining rock samples from this depth, they were able to uncover...

Algae Draws Energy From Other Plants
2012-11-21 11:22:20

Bielefeld University Astonishing research finding by biologists at Bielefeld University published in the online journal Nature Communications Flowers need water and light to grow. Even children learn that plants use sunlight to gather energy from earth and water. Members of Professor Dr. Olaf Kruse´s biological research team at Bielefeld University have made a groundbreaking discovery that one plant has another way of doing this. They have confirmed for the first time that a plant,...

A team of researchers, including a photosynthesis expert from ASU, has found evidence of photosynthesis taking place deep within the Pacific Ocean. The team found a bacterium that is the first photosynthetic organism that doesn't live off sunlight but from the dim light coming from hydrothermal vents nearly 2,400 meters (7,875 feet) deep in the ocean. The discovery of the green sulfur bacteria living near hydrothermal vents off the coast of Mexico has significant implications for the...

Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
