Tobacco: New Resource Of Sugar 2008-01-18 04:55:00 Fructose is a sweetener used in many food products, primarily as a substitute for sucrose. The main reason for its rising popularity with the food manufacturers is the availability of large quantities of corn starch, which can be enzymatically converted to fructose on an industrial scale.An alternative and a cheap source of fructose production could be fructans, the storage carbohydrates in many plants. Fructans are multiple fructose polymers, which can be enzymatically or chemically hydrolyzed to yield fructose.Tobacco
plants which are inserted with the gene of the bacterium bacillus subtilis levansucrase (SacB) are found to accumulate a stable amount of fructan similar to that produced by the microbe. The level of fructan accumulation in these transgenic tobacco plants is quite impressiv Read more:Resource

Mankind’s Little Helpers: 2007-12-14 08:57:00 50 to 100 million, that’s the number of vertebrate animals that scientists worldwide use for experimental reasons annually. An even larger number of invertebrates are used for scientific research, but these experiments on the whole are unregulated by the law and not calculated in annual statistics.These ‘laboratory animals’ are mostly bred in research labs, and even fewer numbers are caught from the wild or are obtained from pounds. Mice, monkeys, dogs, sheep, fruit flies, birds are some of the common animals used for research purposes. Many animals have been instrumental in helping scientists win Nobel accolades as well. For instance, penicillin was tested on mice, organ transplants were experimented using dogs, etc.While the subject of animal research is rather controversial to say
Human Evolution Acceleration: 2007-12-14 07:46:00 Today there are an estimated 6 billion people populating planet Earth. In spite of the many terrors that modern man has created [read nuclear weapons, advanced machinery, global warming, medicine wars, etc.] the Homo sapien race has flourished rather well.Numerous developments in medicine, machinery and agriculture have also facilitated human survival in adverse environs. The human race today can attempt to claim that it can adapt to any environment, albeit a little hesitantly. But such an advanced state of development can hardly point out with clarity that the human race has stopped evolving.A new study pointing to a contrary situation is doing the rounds in scientific circles today though. According to this study, human evolution has accelerated in the past 40,000 years and has zoomed a Read more:Evolution

Helping The Immune System: 2007-12-05 07:11:00 A functioning individual’s immune system is the natural shield the body uses to keep viruses, bacteria and other disease causing organisms at bay. But unlike the respiratory system or the circulatory system, the immune system is a collection of mechanisms that are triggered into action as soon as it detects a virus.For the immune system to detect and successfully destroy an invading virus or bacteria, it is vital that it distinguishes between the infectors and the body’s own healthy cells and tissues. This is a complex task though as these infectors are constantly evolving and adapting themselves to the characteristics of the host.The good news is the extent to which the human body has evolved. Our adaptability to the various ills that come with a continuously changing world has helped Read more:Helping
