Scientists have developed a new kind of tiny motor — which they term a "microrocket" — that can propel itself through acidic environments, such as the human stomach, without any external energy source, opening the way to a variety of medical and industrial applications. Their report in the Journal of the American Chemical Society describes the microrockets traveling at virtual warp speed for such devices. A human moving at the same speed would have to run at a clip of 400 miles per hour....
WASHINGTON, Feb. 7, 2012 /PRNewswire/ -- Citycare Medical Supplier, Inc., providers of Home Oxygen Therapy and Durable Medical Equipment, announced plans today to apply for a GSA Schedule 65 and actively pursue federal contracts. Government officials utilize GSA Schedules as a means of procuring goods and services knowing that companies on these schedules have been qualified by the General Services Administration (GSA). Citycare Medical cited the continued needs of returning veterans...

This is the fourth year in a row for double-digit revenue growth for Spectros since the current T-Stat Oximeter was launched in 2008. "This accelerating growth continues to send a strong signal that the market is embracing the Spectros broadband tissue oximetry," notes CFO John Bagnatori. Spectros T-Stat® is the only broadband tissue oximeter on the...
No need to waste time looking for the right filter for the right oxygen concentrator when these kits are on hand already. Each kit contains an intake filter, cabinet filter and a final bacteria filter, so there will always be a filter ready every time it is needed. Elberton, GA (PRWEB) February 04, 2012 Rehabmart.com, an online e-commerce company that sells rehabilitation and medical supplies, has teamed up with Glenn Medical Systems, Incorporated, to offer oxygen concentrator filters to...
ORMOND BEACH, Fla., Feb. 2, 2012 /PRNewswire/ -- One of the largest costs of monitoring gas levels is the ongoing costs of sensor calibration. The CO2Meter.com line of oxygen and oxygen-carbon dioxide combination sensors drastically reduces maintenance costs by simplifying the calibration process. The TR250Z Oxygen Sensor and Oxygen-Carbon Dioxide Combination Sensor are both designed to be calibrated in-situ with a push of a button using normal room air. This simplified process means...
A new family of proteins which regulate the human body’s ‘hypoxic response’ to low levels of oxygen has been discovered by scientists at Barts Cancer Institute at Queen Mary, University of London and The University of Nottingham. The discovery has been published in the international journal Nature Cell Biology. It marks a significant step towards understanding the complex processes involved in the hypoxic response which, when it malfunctions, can cause and affect the progress of many...
Ultraviolet radiation is the catalyst for cellular damage in phytoplankton The Bren School-based authors of a study published Jan. 20 in the journal PLoS ONE have observed toxicity to marine organisms resulting from exposure to a nanoparticle that had not previously been shown to be toxic under similar conditions. Lead author and assistant research biologist Robert Miller and co-authors Arturo Keller and Hunter Lenihan – both Bren School professors and lead scientists at the UC Center...
Researchers at the RIKEN SPring-8 Center in Harima, Japan have clarified the crystal structure of quinol dependent nitric oxide reductase (qNOR), a bacterial enzyme that offers clues on the origins of our earliest oxygen-breathing ancestors. In addition to their importance to fundamental science, the findings provide key insights into the production of nitrogen oxide, an ozone-depleting and greenhouse gas hundreds of times more potent than carbon dioxide. As the central process by which...
KIT Climate Researchers Studied Ozone Hole Formation - Results in “Geophysical Research Letters“ Extraordinarily cold temperatures in the winter of 2010/2011 caused the most massive destruction of the ozone layer above the Arctic so far: The mechanisms leading to the first ozone hole above the North Pole were studied by scientists of the KIT Institute of Meteorology and Climate Research (IMK). According to these studies, further cooling of the ozone layer may enhance the influence of...
The bottom of a glacier is not the most hospitable place on Earth, but at least two types of bacteria happily live there, according to researchers. The bacteria -- Chryseobacterium and Paenisporosarcina -- showed signs of respiration in ice made in the laboratory that was designed to simulate as closely as possible the temperatures and nutrient content found at the bottom of Arctic and Antarctic glaciers, said Corien Bakermans, assistant professor of microbiology, Penn State Altoona. She...

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...
