Researchers in the U.S. have found a natural means of protection against intestinal roundworm infections. They also say that their findings could pave the way for better treatment measures.

To date, scientists have not been able to figure out how the immune system works to induce "an effective response against tissue dwelling helminthic parasites." So, the new discovery detailing a natural mechanism against these intestinal roundworm comes as a breakthrough in the area of health science

Geneticists have mixed DNA from the roundworm C. elegans and pigs to produce swine with significant amounts of omega-3 fatty acids - the kind believed to stave off heart disease.

Researchers hope they can improve the technique in pork and do the same in chickens and cows

Scientists using genetic engineering have produced pigs rich in omega-3 fatty acids, the kind believed to stave off heart disease.

Geneticists have mixed DNA from the roundworm C. elegans and pigs to produce swine with significant amounts of omega-3 fatty acids - a kind of healthy fat abundant in many fish but not naturally found in meat
