Key protein in cellular respiration discovered
Many diseases derive from problems with cellular respiration, the process through which cells extract energy from nutrients. Researchers at Karolinska Institutet have now discovered a new function for a protein in the mitochondrion - popularly called the cell's power station - that plays a key part in cell respiration. view more (2009-04-08)
Unstable proteins can cause premature ageing
The normal ageing process has long been linked to problems with cell respiration, the process through which the cells extract energy from nutrients. view more (2009-08-06)
Plants' role in global warming re-examined in ORNL Science paper
Estimates of increased plant respiration in response to higher global temperatures may be somewhat overstated as they have not taken into account plants' ability to adjust to changing conditions, according to researchers from Oak Ridge National Laboratory. view more (2006-05-02)
Liquid ventilation
The main problem that premature babies have is that their lungs are not well formed. In order to alleviate this situation, the Nautical School at the University of the Basque Country has developed a liquid respiration respirator. view more (2006-03-29)
The gigantic respiration of crystalline solids
Previously, only amorphous polymer materials approached such levels of performance. On the other hand, these "gigantic respiration" and their respiration, which takes place at constant overall shape, is reversible. This discovery, of interest for numerous industrial applications, is published in the journal Science on March 30, 2007. view more (2007-04-02)
A new brake on cellular energy production discovered
A condition that has to be met for the body to be able to keep warm, move and even survive is that the mitochondria - the cells' power stations - release the right amounts of energy. view more (2007-07-27)
Structure of cog at the hub of metabolism reveals anti-ageing function
The structure of a key energy-releasing enzyme found in all animals is designed to minimise free radical production, an international team of researchers report in the journal Science today. In a startling feat of structural biology, the team visualised the entire molecular structure of succinate dehydrogenase in the bacterium E. coli, allowing... view more... (2003-01-30)
Towards the mechanism of cell respiration
Researchers at the Institute of Biotechnology of the University of Helsinki have for the first time identified an internal electron transfer reaction that initiates the proton pump mechanism of the respiratory enzyme. view more (2006-04-06)
Scientists reveal fine detail of cell`s energy machinery
A molecular pump that helps to keep cells flush with energy has been visualised by scientists at Imperial College, London. The structure of the pump, a key enzyme in bacterial respiration, reveals for the first time one of the molecular mechanisms that underpins cellular respiration, and confirms a Nobel Prize-winning theory proposed over 40... view more...

Adaptation to oxygen deprivation elucidates tumor physiology
Two new studies in the March Cell Metabolism reveal a survival mechanism by which cells adapt to oxygen starvation by ratcheting down their demand. view more (2006-03-08)
Study helps clarify role of soil microbes in global warming
Current models of global climate change predict warmer temperatures will increase the rate that bacteria and other microbes decompose soil organic matter, a scenario that pumps even more heat-trapping carbon into the atmosphere. view more (2008-10-29)
Drop in acid rain altering Appalachian stream water
Appalachian hardwood forests may be getting a respite from acid rain but data from a long-term ecological study of stream chemistry suggests that the drop in acid rain may be changing biological activity in the ecosystem and hiking dissolved carbon dioxide in forest streams. view more (2006-12-12)
Preservation of fresh-cut vegetables; a producer's and consumer's sake
In recent years, new food packaging concepts have been developed to respond on consumption trends towards mildly preserved, fresh convenient food products. Fresh-cut vegetables are an example of fresh-like, healthy convenience foods, developed in the '80s in the UK. Their market is yearly increasing with 25% in West Europe. Packaging fresh-cut... view more... (2002-03-19)
Complex carbon picture clearer
Study shows that more plant litter resulting from higher CO2 could boost the amount of carbon released into the atmosphere. view more (2007-12-12)
Increasing carbon dioxide and decreasing oxygen in the oceans will make it harder for deep-sea animals to
New calculations made by marine chemists from the Monterey Bay Aquarium Research Institute (MBARI) suggest that low-oxygen "dead zones" in the ocean could expand significantly over the next century. view more (2009-04-20)
A computer simulation tool that predicts the influence of forest clearings on soil fertility
The process of clearing consists of cutting down trees in such a way that those remaining have more resources and can grow more. The question was if too many had been cut down, with the concomitant removal of nutrients, and the manner, therefore, in which this process might affect long-term soil fertility. view more (2004-09-08)
Scientists provide new evidence for cellular cause of SIDS
University of Chicago researchers and colleagues have found strong support that a disturbance of a specific neurochemical can lead to sudden infant death syndrome, the primary cause of death before age 1 in the United States. view more (2006-03-08)
New epidemiological review finds no causal association between the use of cellular phones and cancer
The Swedish Radiation Protection Authority has engaged two internationally well-known epidemiologists to review published epidemiological studies on the relationship between the use of cellular telephones and cancer risk. They are Dr. John D. Boice, Jr. and Dr. Joseph K. McLaughlin from the International Epidemiology Institute, USA. In their... view more... (2002-09-20)
Computers explain why pears may become brown during commercial storage
Internal browning of pears stored under low oxygen conditions is related to restricted gas exchange inside the fruit, according to a study published March 7th in the open-access journal PLoS Computational Biology. view more (2008-03-10)
No laughing matter -- bacteria are releasing a serious greenhouse gas
Unlike carbon dioxide and methane, laughing gas has been largely ignored by world leaders as a worrying greenhouse gas. But nitrous oxide must be taken more seriously. view more (2008-03-31)
