Rat Invasion Hurts Coral Reefs!

Rats are known to be a nuisance on land, but now they are indirectly damaging coral reefs. The cycle starts with seabirds feeding from the ocean and eliminating waste onto shore. As tides come in, the ocean sweeps the bird poop, which is rich in nitrogen, into the ocean, allowing sea life to thrive. When small fish populations grow, they feed on seaweed and keep coral reefs healthy. However, when researchers studied islands with rat infestations, seabird, fish and coral reef populations decreased while seaweed and rat populations increased. Rats were feeding on seabird eggs and chicks, which led to less nutritional poop for small fish, which led to a decrease in fish populations, which led to less maintenance of seaweed, and finally leading to seaweed overtaking coral reefs. After scientists studied these turn of events, they came to one conclusion: a species invasion.

What Color is Your Fruit?

Scientists are developing a new wave of GMOs, determining the color of your next meal. People are generally skeptical when it comes to buying genetically modified foods, especially ones with altered colors. However, this new wave of fruits may not be as scary as they seem. “Fresh Del Monte Produce Inc. has engineered a pink pineapple that includes lycopene, an antioxidant compound that gives tomatoes their red color.” Even though this fruit is pending approval by the FDA, it should be safe, as the modification consists of a natural enzyme from tomatoes. Additionally, some gardeners produce conventional purple tomatoes which get their color from anthocyanins, an enzyme found in blueberries which have proven to have affects on cardiovascular disease and cancer. With this new generation of GMOs, no one can predict what color your fruit will be.

Does Blindness Influence Trust?

A study including 32 blind from birth, 27 late blind and 65 sighted men and women was done to see if blindness influences trust. All participants completed a standardized survey measuring their thoughts on other people being exploitative, or dishonest. Results showed that overall the blind participants generally had the same level of trust in others, as those with sight. Even though both groups portrayed the same social trust, both groups believed people are more exploitative, rather than dishonest. In addition, since the experiment included people blind from birth, the data illustrates how visual deprivation over a lifespan does not affect trust levels in others. Overall, this study conveys the insignificance of sight in one's level of trust in others.
