Before the invention of the at-home refrigerator in 1913, it was rare to find a strawberry in the winter or a gala apple in the spring 14 it had been preserved.

When the option to freeze and refrigerate became available, fresh food that was in season in warmer climates could 16 a trip elsewhere for consumption, removing the need for old-time preservation techniques. 17 no longer a necessity, some older methods of storing foods became traditional delicacies. Fruit jams, jellies, and preserves have 18 beyond becoming outdated and remained popular sweet spreads for breads, sandwiches, and many other foods.

Would you ever eat a plant whose genes were altered by scientists in a laboratory? You probably already have, for genetically modified organisms (GMOs), also known as genetically engineered organisms, are 19 in modern food supplies. The concept underlying genetic modification is not new. For centuries, farmers have used a method called selective breeding to produce more 20 crops. They do this by choosing seeds from plants that appear to be particularly 21 to pests and cold or dry weather and planting those seeds in place of weaker strains. Over time, the desirable strains come to dominate the genetic 22 of the farmers’ crops. Not everyone is supportive of the technology, however. Critics point to the fact that GM foods are simply too new to be embraced, 23 that there could exist long-term health risks that have yet to surface. For instance, consumers with allergies have had adverse reaction to the implanted genes.

Post-traumatic stress disorder is a malady of memory. Sufferers are often haunted by recurrent nightmares, distressing thoughts and flashbacks so intense in color, smell and sound that they feel as if they are reliving the trauma. But what if these unbearable memories could be selectively erased? Sheena Josselyn, a professor of physiology and psychology, who studies how the brain encodes, stores and uses information, is intrigued by the idea and has been investigating how to “silence” memories --make them temporarily inaccessible-- in mice. She thinks it’s possible that a variation of this technique could one day help treat post-traumatic stress disorder in humans.
Studies with mice have found that although their brains contain billions of neurons, only a few are necessary to form a fearful memory. Researchers working with mice began by teaching them to fear a tone: when it sounds, they feel a mild shock to their feet (not to hurt them, just to scare them). The next time the mice hear the tone, they crouch and freeze, signaling fear. The researchers discovered that they could trigger the memory of that fear even without presenting the tone. They did this by stimulating the small group of nerve cells holding that memory through a technology called optogenetics. Using the same technology, they found they could also suppress the fearful memory. With optogenetics, scientists insert proteins into neurons to make them sensitive to light. Depending on the type of protein and color of light used, these cells can then be activated or deactivated by shining pulses of the light directly into the brain. If the light activates the cells, the mice freeze as if they’ve just heard the tone. If the light deactivates the cells, the memory is suppressed. While optogenetics is an invasive procedure and technologically not feasible with humans, Josselyn hopes that the general principles learned from these studies could eventually help scientists create new drugs for treating memory disorders such as post-traumatic stress disorder and Alzheimer’s.
But should you erase a bad memory? Absolutely not, says Josselyn. She emphasizes that this future technology should not be applied to everyday bad things, and that these discoveries need to go hand in hand with a real thinking about the ethics involved in potentially manipulating memories in people. Their use would only be considered in extreme cases after all other treatment options have been explored. The goal is not to sanitize life or make people super happy, but rather to make everyone a functional person, capable of moments of joy.
