[Title] => What it takes to be a scientist in a developing country
[Summary] =>
Scientists are people who make science their lifetime work or career. To be a scientist, one must adhere to the rules of the vocation and its code of conduct, as in any profession.
Science, defined as "systematic knowledge based on study and observation," is the way by which mankind has gained its stock of knowledge about itself, its surroundings and the laws of Nature. It has helped man provide for his basic needs and sustain his further development and survival.

[Title] => Wastewater good for aquaculture
[Summary] => Wastewater from kitchen sink and washing machine, known as "gray water," can be used for growing aquatic plants and fish.
Attesting to this are studies done by Aquatic Biosystems, a private R&D group based in Laguna Bay, monitored by the Los Baños-based Philippine Council for Aquatic and Marine Research and Development (PCAMRD).
In tests, it was found that with the use of kitchen wastewater, kangkong (Ipomea aquatica) had a growth that was favored with up to 20 percent concentration for the wastewater in the culture medium.

[Title] => Earthworms good as feed for fish, crabs
[Summary] =>
Cultured earthworm is a good substitute for "trash fish" as foods of fish and crabs grown in cages.
This was found in a study done by Philip Cruz, president of the Cruz Aquaculture Corp. (CAC) in Bacolod City (Negros Oriental).
"With the cost of only P10 for producing a kilo of fresh earthworms using agricultural wastes, it is more attractive to use earthworms instead of ‘trash fish’ for feeding fish," reported Cruz, who conducted a research titled "Prospects of Raising Earthworms for Aquaculture Feeds."

[Title] => Cultured earthworms as human food
[Summary] => In a television reality show, a man was shown eating a lot of live earthworms with gusto. This was repulsive to many viewers. Are earthworms really edible? Are they safe to eat?
Earthworms are terrestrial invertebrates that have been used as human food for ages. They are in fact considered a delicacy by the natives of Africa, South America, Japan, China, Papua New Guinea, and New Zealand.

[Title] => ‘Earthworm power’ gains momentum
[Summary] => And now, "vermiceuticals".
These are health-enhancing food supplements produced from earthworms, products of scientific headways achieved by the research sector.
"The most exciting and challenging area of earthworm science and technology in the world today is in the discovery, exploration, and production of nutriceuticals or vermiceuticals from earthworms," said Dr. Rafael D. Guerrero III, executive director of the Los Baños-based DOST-Philippine Council for Aquatic and Marine Research and Development (PCAMRD).

[Title] => Vermicomposting: A maturing technology
[Summary] => Call it a "maturing technology."
Vermicomposting, the use of earthworms for composting biodegradable materials, is an environment-friendly and efficient way of converting farm and household wastes into useful products.
The method produces vermicompost that can be used as a soil conditioner and organic fertilizer as well as earthworm biomass that can be processed into vermimeal for feeding fish and livestock.
