Reading and Writing #4 (short passage)

Getting a vaccination could soon be as simple as eating a potato. Researchers at the University of Maryland, led by Dr. Carol Tacket, are developing edible vaccines that could grant immunity against some diseases.

To be inoculated against a virus, bacterium, or toxin, the antibodies of our immune systems must be exposed to the illness-bearing agent, or pathogen. Vaccines work by exposing the body to pathogens that have been killed or disarmed. Once sensitized, antibodies can mobilize rapidly against familiar enemies by binding to them and preventing their growth and activity.

Most vaccines are delivered in shots or pills, but the new one will be incorporated in raw potatoes. The potatoes have been genetically engineered to produce the key piece of an E.coli toxin that causes acute diarrhea. As the spuds move through the intestinal system and are digested, the toxin fragment is released and exposed to the immune system, which then generates antibodies against the toxin.

Dr. Tacket’s group is waiting for approval from the FDA to test the potato vaccine on humans; it has already been tested successfully in mice. The next step would be to genetically modify bananas to carry vaccines, because raw bananas taste better than raw potatoes.

The potential for edible vaccines is tremendous, especially in developing countries. Whereas current vaccines are expensive to produce, store, transport, and administer, an edible vaccine could be grown where it is needed in the quantity desired, and requires considerably less medical expertise to use.

Reading and Writing #2 (short article)

Just a few minutes’ chatting on a mobile phone reduces the brain functions of children for almost an hour, according to new Spanish test results quoted in Norwegian media.

The tests, conducted by the German investigator Michael Klieeisen at the Spanish Neuro Diagnostic Research Institute in Marbella, are the first to show how children’s brains react to the use of mobile phones. With the help of a scanner, Klieeisen was able to create pictures of how the brains of an 11-year-old boy and a 13-year-old girl reacted while they used a mobile phone. The results were compared with similar tests using adult subjects.

The tests showed that the brain activity of the child subjects was reduced significantly, especially on the side where the mobile phone was held, a few minutes after the call was begun, the report said. Also, brain activity was lower than normal in large sections of the brain for 50 minutes after the end of the call, the test results showed.

“My advice to all parents is not to allow children to use mobile phones.” Klieeisen was quoted by Aftenposten as saying. “Not only are electrical activities affected, but also bio chemical processes. We do not know if it is dangerous, but we do know that children’s brains, which are not fully developed, are more vulnerable than adult brains are,” the researcher added.

Researchers in Britain confirm the Spanish results, and Norwegian and Swedish experts are also studying the health risk posed by mobile phones.
