Pittsburgh-based InventHelp attempts to submit clients´ inventions to companies for review. PITTSBURGH, PA (PRWEB) June 18, 2013 InventHelp, America´s largest invention submission company, announces that one of its clients, an inventor from Texas, has designed an adjustable, rolling walker that could feature attachments to carry oxygen tanks and IV bars. This invention is patented. The “IV-Oxygen Walker” could provide a medical patient with more freedom, mobility and...

Meteorites Brought Phosphorus Life To Earth
2013-06-05 12:53:49

Lee Rannals for redOrbit.com - Your Universe Online New research published in the Proceedings of the National Academy of Sciences has determined that meteorites that impacted Earth some 3.5 billion years ago could have helped kick start life on this planet. Scientists at the University of Washington and the University of South Florida have found that the heavy bombardment by meteorites early in our planet´s history provided the reactive phosphorus that was essential for the...

Chemical Reaction Could Provide Energy For Martian Microbes
2013-05-31 12:02:17

Brett Smith for redOrbit.com - Your Universe Online Previous research has shown how rock-water reactions can produce hydrogen when temperatures are far too hot for living things to survive, such as near hydrothermal vent systems on the ocean floor. However, a new study in Nature Geoscience reports that the same hydrogen-producing reaction can also occur at more hospitable temperatures. "Water-rock reactions that produce hydrogen gas are thought to have been one of the earliest sources...

New Method For Producing Clean Hydrogen Developed
2013-05-22 12:11:39

Duke University Duke University engineers have developed a novel method for producing clean hydrogen, which could prove essential to weaning society off of fossil fuels and their environmental implications. While hydrogen is ubiquitous in the environment, producing and collecting molecular hydrogen for transportation and industrial uses is expensive and complicated. Just as importantly, a byproduct of most current methods of producing hydrogen is carbon monoxide, which is toxic to...

Possibility Of A More Dynamic Biological Oxygen Cycle On The Early Earth Than Previously Thought
2013-04-25 10:22:56

University of California, Riverside A research team of biogeochemists at the University of California, Riverside has provided a new view on the relationship between the earliest accumulation of oxygen in the atmosphere, arguably the most important biological event in Earth history, and its relationship to the sulfur cycle. A general consensus exists that appreciable oxygen first accumulated in Earth's atmosphere around 2.4 to 2.3 billion years ago. Though this paradigm is built upon a...

All Possible Drug-like Chemical Compounds Mapped By Scientists
2013-04-23 09:00:43

Duke University Software builds "library" of millions of small, carbon-based molecules chemists might synthesize. Drug developers may have a new tool to search for more effective medications and new materials. It's a computer algorithm that can model and catalogue the entire set of lightweight, carbon-containing molecules that chemists could feasibly create in a lab. The small-molecule universe has more than 10^60 (that's 1 with 60 zeroes after it) chemical structures. Duke...

Sewer Gas Accelerates Plant Growth, Development
2013-04-18 18:14:55

Brett Smith for redOrbit.com — Your Universe Online Hydrogen sulfide, known to many as ℠sewer gas,´ is a deadly substance that many evolutionary biologists blame for several mass extinction events throughout Earth´s history. However, according to a new study in the open access journal PLOS ONE, very low doses of the pungent compound spur plant growth. The study´s lead researcher Frank Dooley, a University of Washington doctoral student, said he stumbled...

Primitive Batteries Helped Power Primordial Soup

April Flowers for redOrbit.com - Your Universe Online A research team at the University of Leeds may have solved the question of how objects from space could have kindled life on Earth. Scientists generally accept that some of the important ingredients for life came from meteorites impacting the early Earth. However, they have not been able to explain how that inanimate rock transformed into the building blocks of life. The new study, published in Geochimica et Cosmochimica Acta,...

Acid Rain
2013-04-01 10:21:17

Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...
