Biosafety

Biosafety: prevention of large-scale loss of biological integrity, focusing both on ecology and human health.

Biosafety is related to several fields

- in ecology (referring to imported life forms from beyond ecoregion borders),

- in agriculture (reducing the risk of alien viral or transgenic genes, or prions such as BSE/"MadCow", reducing the risk of food bacterial contamination)

- in medicine (referring to organs or tissues from biological origin, or genetic therapy products, virus; levels of lab containment protocols measured as 0, 2, 3, 4 in rising order of danger),

- in chemistry (i.e.nitrates in water, PCB levels affecting fertility) and

- in exobiology (i.e. NASA's policy for containing alien microbes that may exist on space samples - sometimes called "biosafety level 5").

The international Biosafety Protocol deals primarily with the agricultural definition but many advocacy groups seek to expand it to include post-genetic threats: new molecules, artificial life forms, and even robots which may compete directly in the natural food chain.

Biosafety in agriculture, chemistry, medicine, exobiology and beyond will likely require application of the precautionary principle, and a new definition focused on the biological nature of the threatened organism rather than the nature of the threat.

When biological warfare or new, currently hypothetical, threats (i.e. robots, , new artificial bacteria) are considered, biosafety precautions are generally not sufficient. The new field of biosecurity addresses these complex threats.

After Drought, Diversity Dries Up And Ponds All Look The Same
An ecologist has discovered that after ponds dry up through drought in a region, when they revive, the community of species in each pond tends to be very similar to one another, like so many suburban houses made of ticky tacky.

Metabolic Syndrome Heightens Risk For Development Of Uric-acid Kidney
Researchers have found that patients suffering from the metabolic syndrome -- a cluster of conditions that increases the risk for heart disease, stroke and diabetes -- also have a propensity to develop highly acidic urine, which increases the risk of developing kidney stones.

New Classification Of Eukaryotes Has Implications For AIDS Treatment,
The first major higher level classification of all organisms (with the exception of bacteria), coordinated by the International Society of Protistologists, overturns previously held scientific assumptions. 28 experts representing the fields of microbiology, mycology, parasitology, phycology, and protozoology contributed to this joint effort, which incorporates new data, obtained in the past 25 years, in such diverse areas as biochemistry and metabolism, electron microscopic structure, and gene sequences.

Antibiotic Treatment For Children With Urinary Tract Infections Not As
The use of prophylactic antibiotics, which involves daily administration of antibiotics to children after an initial urinary tract infection, is not associated with reduced risk of recurrent urinary tract infections, but is associated with an increased risk of resistant infections, according to a new study.

Gravely Gorgeous: Gargoyles, Grotesques &the Nineteenth-Century Imagin
This site is a companion to an exhibit about the admiration by Victorians of the Gothic style of architectural decoration of cathedrals, which featured gargoyles ("decorative waterspouts that preserve stonework") and grotesques (that "serve a variety of other practical and ornamental functions, as corbels or capitals, for instance"). Includes a gallery of images and a glossary. From the Division of Rare and Manuscript Collections, Cornell University Library.

Engineers Find Way To Make Ethanol, Valuable Chemicals From Waste Glyc
With U.S. biodiesel production at an all-time high and a record number of new biodiesel plants under construction, the industry is facing an impending crisis over its major waste byproduct, glycerin.Researchers have now developed a possible solution, a new biotech process to convert glycerin into ethanol, another popular biofuel. Chemical engineers estimate the operational costs of the process to be about 40 percent less that those of producing ethanol from corn.

Wisconsin Researchers Identify Sleep Gene
Zeroing in on the core cellular mechanisms of sleep, researchers at University of Wisconsin Medical School have identified for the first time a single gene mutation that has a powerful effect on the amount of time fruit flies sleep.

College of Forest Resources Fact Sheets
This series of fact sheets covers forestry topics such as forest engineering, policy, marketing and trade of forest products, restoration and remediation, and urban forestry. Publications concern forests and forestry in Washington state and beyond. From the University of Washington College of Forest Resources.

Hurricane Katrina Images
"The imagery posted on this site is of the Gulf coast of Louisiana, Mississippi and Alabama after Hurricane Katrina made landfall. This imagery was acquired by the NOAA Remote Sensing Division to support NOAA national security and emergency response requirements."Aerial photos are accessible through an interactive map.

More Than Meets The Tongue: Color Of A Drink Can Fool The Taste Buds I
Does orange juice taste sweeter if it's a brighter orange? A new study in the March issue of the Journal of Consumer Research finds that the color of a drink can influence how we think it tastes. In fact, the researchers found that color was more of an influence on how taste was perceived than quality or price information.
