Biomass

Biomass is the organic non-fossil material of biological origin, collectively. For example, plants (including trees) and animals are biomass, as are the materials they produce, such as animal droppings and wood. The most successful animal of the earth, in terms of biomass, is the Antarctic krill, Euphausia superba, with a biomass of probably over 500 million tonnes, roughly twice the total biomass of humans.

Biomass is sometimes burned as fuel for cooking and to produce electricity and heat. Biomass used as fuel often consists of underutilized types, like chaff and animal waste. This is often considered a type of alternative energy although it is not a non-polluting one. In some industrialized countries, like Germany, paradoxically, food is cheaper than fuel compared by price per joule. Central heating units supplied by food grade wheat or maize are available.

New Particle Discovered By BaBar Experiment, Revealing Secrets Of Stro
Its name is Y(4260) and it is not a new humanoid of Stars Wars, but a particle identified for the first time by BaBar experiment: an international collaboration - formed by the large participation of the Italian physicists of the National Institute for Nuclear Physics (Infn) - that has its seat in Stanford (California).

Early Indicator Of Kidney Disease May Also Predict Risk Of Pre-diabete
A blood component called cystatin C, used to test for early-stage kidney impairment, also may be a very early marker for those at risk of developing a condition known as pre-diabetes, a study conducted by researchers at the University at Buffalo has shown.

Long-term Aspirin Use Reduces Risk For Colorectal Cancer
A new report from the Nurse's Health Study finds that regular, long-term aspirin use can significantly reduce the risk of colorectal cancer. However, the benefit appears to require more than a decade and is strongest at dose levels associated with a greater risk of side effects such as bleeding.

New Mathematical Model Unravels The Mechanics Of Microbe Reproduction
In process that is shrouded in mystery, rod-shaped bacteria reproduce by splitting themselves in two. By applying advanced mathematics to laboratory data, scientists have solved a small but important part of this reproductive puzzle.

Z-shaped Incision Enhances Minimally-invasive Surgery
A novel surgical technique allowing doctors to operate on patients by making a Z-shaped incision inside the stomach could potentially replace certain types of conventional surgery in humans, according to medical researchers who have successfully demonstrated the procedure in pigs.

Building A Tree Of Life Needs Less 'Wood'
Building a "tree of life"for all the species on the planet may be easier than first thought, according to a study by UC Davis researchers published in the journal Science Nov. 12.

Passive Smoking In Childhood May Increase Risk Of Lung Cancer In Later
Children who are exposed to environmental tobacco smoke (passive smoking) are at a higher risk of developing lung cancer as adults, says a paper in this week's BMJ. Those children exposed to passive smoking on a daily basis and for many hours are the most vulnerable -- facing over treble (3.63) the risk of those who grew up in smoke-free environments.

Strawberry Latent Ringspot Virus Found In North America
Strawberry latent ringspot virus, a problem for the past 30 to 40 years in Europe, has just been discovered in North America by Agricultural Research Service (ARS) scientists and cooperators.

Gulf Warm-water Eddies Intensify Hurricane Changes
Scientists monitoring ocean heat and circulation in the Gulf of Mexico during Hurricanes Katrina and Rita have a new understanding of how these tropical storms can gain intensity so quickly: The Gulf of Mexico's "Loop Current"is likely intensifying hurricanes that pass over eddies of warm water that spin off the main current.
