Blend of Microbes and Plants Can Clean Up Toxic Spills
|
Toxic spills has been plaguing
the environment quite some time now. The hazardous combination of
chemical material are stubborn to clean and nearly impossible to remove
completely. However, a new study in University of Florida may just
provide the solution against contaminants of such caliber.
The study came up with
two of the likeliest candidates for such large scale cleanups, the
loblolly pine and soil-dwelling, methane eating bacteria known as
methanotrophs.
Phytoremediation, the practice of planting chemically-resistant trees
and plants in contaminated sites is highly appealing and despite being
in its infancy, it has the potential to be a relatively safe, sustainable
and efficient method.

Fuel from Madagascar
|
The development of bio-diesel,
an alternative fuel produced by blending vegetable-based oils with
petroleum diesel, is aimed at quenching the insatiable thirst of society
for energy. At the same time, its implementation is touted to be able
to cut carbon emissions by 80%, making it a reliable and low environmental
impact source of fuel. In line with global efforts in reducing carbon
emissions, British-based bio-energy firm D1 Oils intends to set up
plantations in Madagascar producing raw materials for manufacturing
bio-diesel. The plants involved are drought-resistant jatropha trees
which are able to grow on poor, arid soils. Their production rate
of 2.7 tons of oil per hectare makes them the most viable according
to D1. The project partially funded by USAID is expected to increase
the national income of Madagascar by something in the order of US$100
million, a welcome boost for a country known as one of the world’s
poorest nations.

‘golden rice’ could help tackle childhood blindness |
| Vitamin
A deficiency though rarely lethal has a widespread effect on the human
population. According to the estimates of the World Health Organisation,
approximately 500,000 children go blind each year due to vitamin A deficiency.
To counter such devastation to our future generations, UK scientists
have developed a new genetically-modified strain of golden rice with
20 times more beta-carotene, a precursor required to produce vitamin
A.
Despite environmental
and safety concerns as field trials have not been started in Asia, Project
Manager Dr. Jorge Mayer believes that it will be one of the solutions
to fully prevent illnesses related to Vitamin A deficiencies.

| Experts:
Mosquito virus could help beat AIDS |
| Acquired
Immune Deficiency Syndrome (AIDS), is one of the most devastating global
epidemic of the 20th century. According to UNAIDS estimates, as of December
2000, there were an estimated 36.1 million people living with HIV/AIDS;
and since the epidemic began, an estimated 21.8 million people have died
of the incurable disease.
Recently, a research team in Queensland has created much buzz, as
they discovered a virus found in north Australian mosquitoes which has
the potential to provide a basis for vaccines against AIDS and a cure
for cancer. The Kunjin virus, produces a gene which alerts the immune
system about bad cells, and the team is currently teaching the immune
system to recognize cancer cells.
According to a team
member, molecular virologist of the University of Queensland, Alex Khromykh,
trials in mice have been promising, however human trials would have
to be at least five years away.
