'''Rat Invasion Hurts Coral Reefs!'''
+
Tenzin's Article Summary Page
  
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.

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.

Article 1


Friendly Neighborhood Spider



Spiders might seem dangerous, and you might want to kill them on sight; but, spiders are mostly harmless and help the ecosystem.
Spiders may be providing services like eating pests—some even eat other spiders.
There’s even a species of jumping spider that prefers to eat blood-filled mosquitoes in African homes.
Although they are generalist predators, apt to eat anything they can catch, spiders regularly capture nuisance pests and even disease-carrying insects.
So killing a spider doesn’t just cost the arachnid its life, it may take an important predator out of your home.
All in all, you shouldn't be afraid of harmless spiders.Spiders might actually be useful in your houses, for they can get rid of other annoying, yet more dangerous, insects lurking around.


Article 2


The Consequences of Zit Popping



Popping a zit or a pimple may seem like the right thing to do, but it can cause you even more problems.
By popping a zit, it will become an open wound, and potentially infectious bacteria will enter your body.
You can get a scar and picking at or popping any zit makes permanent marks more likely by increasing inflammation.
If you pop a zit and there is no infection or scar, you would still be spreading more zits around.
Therefore you should pop zits because it will end up badly.


Article 3


Can Humans Die from Apple Seeds?



Apple seeds are actually poisonous and can kill humans.
First, the amygdalin/poison, is accessible only if the seeds have been crushed or chewed; a whole unbroken seed will pass right through
But you would need a lot of crushed apple seeds.
When in the digestive system, this chemical degrades into highly poisonous hydrogen cyanide (HCN). A lethal dose of HCN can kill within minutes.
The human body can process HCN in small doses, so a couple of chewed seeds are usually completely harmless.
The average adult would need to eat anywhere from 150 to several thousand crushed seeds (depending on the apple variety) to be at risk of cyanide poisoning.
All in all, apple seeds are only dangerous if you eat a whole lot of crushed seeds, which hopefully, will never happen.
