Genetic engineering

Environmental contamination with heavy metals is often the result of various types of industrial processes. Because heavy metals can be dangerous to humans and other wildlife, contaminated sites need to be cleaned up. This isn't easy. Chemical extraction methods can introduce different types of pollutants into the environment.

Bioremediation -- using biological organisms to clean polluted areas -- is a hot area of research. Some plants can naturally sop up heavy metals without any ill effects, but plants don't always grow large enough to soak up all the pollution. Besides, plants can't be used to clean up contaminated water.

So, scientists have increasingly chosen to use the techniques of biotechnology to create genetically engineered microbes capable of gobbling up...

For years now, we've been writing about and assessing the importance to Americans' nutrition from organic foods (not very) and genetically modified (GMO) or genetically engineered foods (potentially highly). Based on comments from our own website and journalists' reports in the popular media, it's been hard to tell what people (except for activists pro and con) really think. Nearly two years ago we noted how different the assessments of scientists and non-scientist consumers were with respect to GMO foods, for example. Thus it's instructive to examine a recent report from the Pew Research Center about attitudes...

At this time of year, we look forward to feasting to celebrate the holidays. But, as Earth's population grows, feasts may become more scarce.Currently there are more than 7 billion people on the planet; according to some authorities, the increase in population between 1900 and 2000 was greater than that in all of human history. Although these same folks note that the rate of population growth has been slowing, we can still expect that by the year 2100, there will be over 11 billion people hanging around this planet. So, how are we going to feed them all? No, organic agriculture isn't going to do it. Genetic engineering will be needed to help increase food production. And scientists are working constantly to find new and...

If it seems that the Americans are always a step behind our British counterparts with respect to stem cell research, it s because they are.

Last year, the United Kingdom s House of Commons voted overwhelmingly in favor of fertility treatments using mitochondrial DNA (mtDNA) replacement therapy (MRT), to enable women with heritable...

It's been said (many times) before, but bears repeating that pretty much all our foods have been genetically modified and not just by the modern technology of genetic engineering. Farmers and agricultural researchers have been selecting and cross-breeding plants for millenia to get rid of unwanted traits and emphasize ones they want. And...

shutterstock_269884550With its decision to approve genetically modified (GM) salmon not even a month old, the FDA is advancing science once again. This time officials have approved a GM chicken, but this approval is much different than the last.

AquaBounty's GM salmon, which contains genes from other salmons so it grows big fast, is intended for human...

blood-glucose-meter-1318261-640x480The holy grail of diabetes research has long been finding a way to administer insulin by mouth. And that goal may have been reached by scientists at the University of California at Santa Barbara.

Insulin, the hormone produced by the pancreas' beta-cells, was first identified in 1921. Individuals with Type 1 diabetes essentially make no insulin of their own and if it isn't replaced, they...

Organic farmers must obey certain guidelines to be in compliance with organic rules for example they can't grow genetically engineered (GM) crops, use synthetic pesticides or fertilizers. They have on some occasions complained that neighboring farmers put their organic crops at risk if wind-blown pollen from non-organic crops (especially genetically engineered ones) drift into their fields and "contaminate" their crops.

Well, last year in Australia, an organic farmer actually sued a...

UnknownNo, pigs aren't flying yet, but according to an account in the British paper The Guardian, scientists are working on a way to make domestic pigs resistant to African swine fever, a highly contagious ailment that requires slaughtering of infected animals. In Poland this summer, there have been outbreaks of this disease, and at least 6,000 animals are scheduled to be killed. Obviously, this is a big problem for pig farmers especially poor ones (and of course for all...

We have to give a shout-out to freelance science writer Kavin Senapathy for her interview on dnaindia.com. Senapathy eloquently conveys the facts on genetically modified food for the article: Organic vs GM: finding the grain of truth.

When asked why she advocates the consumption of genetically modified foods, Senapathy quotes the father of the Green...
