Sulphur and iron compounds have been found in shipwrecks off the coast of Sweden and in the Baltic Sea, according to a new study. The group behind the results includes scientists from the University of Gothenburg and Stockholm University. The results were presented recently in the Journal of Archaeological Science. Scientists reported large quantities of sulphur and iron compounds in the salvaged 17th century warship Vasa a few years ago. This resulted in the development of sulphuric acid...
It may seem counterintuitive, but one way to reduce carbon dioxide emissions to the atmosphere may be to produce pure carbon dioxide in powerplants that burn fossil fuels. In this way, greenhouse gases — once isolated within a plant — could be captured and stored in natural reservoirs, deep in Earth's crust. Such "carbon-capture" technology may significantly reduce greenhouse gas emissions from cheap and plentiful energy sources such as coal and natural gas, and help minimize fossil...
EVERETT, Wash., May 15, 2012 /PRNewswire/ -- Fluke Biomedical announced today the newest addition to their ProSim family of patient monitor quality-assurance testing and troubleshooting tools, the SPOT Light SpO2 Functional Tester. Citing a record 15-second preventive maintenance (PM) test for SpO2 patient monitor functionality, the new ProSim SPOT Light is the fastest SpO2 functional tester ever achieved by this industry-leading company.

A detailed description of development of the first practical artificial leaf — a milestone in the drive for sustainable energy that mimics the process, photosynthesis, that green plants use to convert water and sunlight into energy — appears in the ACS journal Accounts of Chemical Research. The article notes that unlike earlier devices, which used costly ingredients, the new device is made from inexpensive materials and employs low-cost engineering and manufacturing processes. Daniel...

Masimo's breakthrough infant and neonatal sensor enhancements offer stellar performance,...
Tulane team's research may hold promise for veteran amputees, diabetics, accident victims A research team at Tulane University will report this week that the application of high levels of oxygen to a severed bone facilitates bone regrowth, study results that may one day hold promise for injured soldiers, diabetics and other accident victims. The results of the Department of Defense-funded study will be presented at 12:25 p.m. Monday April 23, at the American Society for Biochemistry and...
Harnessing the energy of sunlight can be as simple as tuning the optical and electronic properties of metal oxides at the atomic level by making an artificial crystal or super-lattice ‘sandwich’ says a Binghamton University researcher in a new study published in the journal Physical Review B. "Metal oxides are cheap, abundant and 'green,'" said Louis Piper, assistant professor of physics at Binghamton University. "And as the study proved, quite versatile. With the right touch, metal...
How hydrogen--the most abundant element in the cosmos--responds to extremes of pressure and temperature is one of the major challenges in modern physical science. Moreover, knowledge gleaned from experiments using hydrogen as a testing ground on the nature of chemical bonding can fundamentally expand our understanding of matter. New work from Carnegie scientists has enabled researchers to examine hydrogen under pressures never before possible. Their work is published online in Physical Review...

Oxygen therapy is known as the administration of oxygen as a medical intervention. It is indicated in patients whose oxygen supply is compromised due to both acute and chronic health conditions and can be administered in many different ways. Oxygen therapy can be administered virtually wherever the patient is. Most commonly, oxygen is delivered to patients in an ambulance, hospital, or doctor’s office. These medical facilities carry oxygen in the form of a compressed gas. It is stored...
The Paleoproterozoic is the first of three subdivisions of the Proterozoic Eon (occurring from 2.5 billion to 1.6 billion years ago (Ga). This period is marked by the first stabilization of the continents, and also when cyanobacteria--a type of bacteria that uses biochemical processes of photosynthesis to produce oxygen--evolved. Experts have found paleontological evidence that during at least part of the Paleoproterozoic era, about 1.8 Ga, the earth year was about 450 days long, with days...
Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...
