Deep sea algae connect ancient climate, carbon dioxide and vegetation

Assistant Professor Mark Pagani in the Department of Geology and Geophysics at Yale and his colleagues mapped the first detailed history of atmospheric carbon dioxide between 45 - 25 million years ago based on stable isotopes of carbon in a National Science Foundation study reported in Science Express. "Through the energy we consume, each of us makes a contribution to increasing greenhouse...

Storing carbon to combat global warming may cause other environmental problems, study suggests

Growing tree plantations to remove carbon dioxide from the atmosphere to mitigate global warming -- so called "carbon sequestration" -- could trigger environmental changes that outweigh some of the benefits, a multi-institutional team led by Duke University suggested in a new report. Those effects include water and nutrient depletion and increased soil salinity and acidity, said the researchers.<...

Scientific issues associated with carbon-neutral energy sources such as cellulosic ethanol

Professor Chris Somerville of the Carnegie Institution and Stanford University, explained advances in plant science research that are both needed and achievable to reduce costs and multiply current levels of production of biofuels from plant cellulose (biomass). Somerville presented his talk, "Bioenergy: The 21st Century Challenge to Plant Biologists" at the Annual Meeting of the American...

Motorola researchers develop selective sensors based on carbon nanotubes

A team of researchers from Arizona State University and Motorola Labs, the applied research arm of Motorola Inc., has developed sensors based on carbon nanotubes, microscopically small structures that posses excellent electronic properties. In early tests, the new devices detected the presence of heavy metal ions in water down to parts per trillion levels. Specifically, the researchers de...

Microbe has huge role in ocean life, carbon cycle

Researchers at Oregon State University and Diversa Corporation have discovered that the smallest free-living cell known also has the smallest genome, or genetic structure, of any independent cell - and yet it dominates life in the oceans, thrives where most other cells would die, and plays a huge role in the cycling of carbon on Earth. In nature, apparently, bigger is not always better.</...

The Analysis of Polycyclic Aromatic Hydrocarbons (PAHs) by LC/MS/MS Using an Atmospheric Pressure Photoionization Source

The atmospheric pressure photoionization source, PhotoSpray ion source (Robb, Covey and Bruins1) uses photons to ionize large quantities of a dopant molecule added along with the vaporized mobile phase. Analyte molecules are efficiently ionized through secondary reactions initiated by the charged dopant. This new tec...

Carbon monoxide passes down

Legislation pointed at reducing carbon monoxide emissions has resulted in a drop in poisoning deaths. Carbon monoxide can be fatal if inhaled and is involved in a number of accidental deaths and suicides each year. //The main sources of carbon monoxide are vehicle emissions and malfunctioning domestic heating equipment. In 1980, the Clean Air Act was passed in the US to reduce carbon monoxide. Th...

Damage to arteries from injury can be avoided with carbon monoxide

Heart ailments that are treated with angioplasty or a transplantation may result in injury of the arteries. While in transplantation there is an ever-present risk of rejection of the// organ, in angioplasty, placing a balloon in the artery causes damage to the vessel walls. This in turn triggers the immune system response. A new study has however, revealed that pre-treatment with carbon monoxide...

Hearing loss can happen from regular exposure to carbon monoxide

Animal studies have shown the regular exposure to carbon monoxide can damage// the ears of young children. Carbon monoxide enters into the atmosphere from kerosene and gas stove combustions, generators and other liquid fuel powered equipments, car exhaust and tobacco smokes. At moderate concentrations carbon monoxide can cause angina, poor vision, and at times brain function impairment...

Research Shows Carbon Monoxide Prevents Inflammations

Researchers from the University of Michigan Cardiovascular Center had presented new findings// on the properties of the gas carbon monoxide that can cure inflammations in patients who had undergone organ transplants, strokes, or heart attacks. In a recent study the scientists had found that inhaling small amounts of carbon monoxide for several weeks after transplant surgery prevented t...

Protein Carbonyl Level Causes Oxidative Protein Damage In Diabetics

Oxidative stress is considered to be a unifying link between diabetes mellitus (DM) and its complications, including nephropathy.// There is sufficient evidence on increased production of oxidants and decreased level of antioxidants in diabetic patients. The dialysis procedure contributes to oxidative stress. An increase in oxidative stress may contribute to the development of oxidative protein d...
