TETRIS HELPS PREVENT FLASHBACKS

-Post-traumatic stress disorder (PTSD), was discovered at Oxford University and a result to fix it is to play Tetris.
-Tests show that Tetris reduces the number of flashbacks to those who have bad scenes in the following week.
-Tetris disrupts the memories that are retained by the sights and soundsof the bright and colorful computer game.

*The Oxford team showed a film to 40 healthy volunteers that included traumatic images of injury from a variety of sources, including adverts highlighting the dangers of drink driving. This is a recognised way to study the effects of trauma in the laboratory. After waiting for 30 minutes, 20 of the volunteers played ‘Tetris’ for 10 minutes while the other half did nothing. Those who had played the computer game experienced significantly fewer flashbacks to the film over the next week

Bacteria Playing A Bigger Role In Fossils

-"Paleontologists were stunned when fossils appearing to belong to the soft-tissued embryos of marine creatures were unearthed in Chinese sediments a decade ago," says Science News.
-Tests are pointing to a process of three stages, two of which directly involve bacteria common in marine sediments, can reproduce the same fossilization effect in modern embryos.
-"First, the fragile embryonic tissues must end up in an oxygen-poor environment that shuts down autolysis, the enzyme-driven process that, in essence, digests the cell from the inside out," says Science News again.

Fiddler Crabs

-Male Fiddler crabs are considered "liars as their big claws make them look bigger than they appear or seem, because they are actually pretty weak.
-They do this so they look like competition for other male crabs.
-They are just two centimeters across so can the "big" claws really hurt that bad maybe for another crab but not really so much for anything else.

Food Webs

-In science class, we are learning about food webs. Food webs are the order in which an animal eats a different type of species, from smaller to larger, or whoever has more power to kill their prey. To the left is an example of a food web ranging from, plants to owls. The most energy is absorbed by the plants or producers, which gets passed on from species to species and the consumer at the top of the food web receives the least amount of energy from the lower level species at the food web.

-He's the son of a NASA astronaut Owen Garriott, he’s the first second generation astronaut.

Math Blog

This year has been very informative and we learned new things such as proportions, fractions(add,subtract,multiply,divide), etc. One day if I become a banker I will remember Mr.Boehm hopefully to thank him for teaching me the basics of interest and fractions.
We learned how to figure out I=PTR which means interest is equal to principal amount x time x ratio which is percent. In life you could use this if you are buying a car our any household appliances(electricity)
Or probabilities if I want to bet on a horse or the lottery. Or fractions when cooking or percentages when writing out checks and taxes.
We also learned how to add and subtract decimals. That will help us when we buy from a store, which also includes needing to know percentages so we know how much tax we will need to pay.
This year I have learned many things, but next year I’m hoping that I will be able to comprehend better and also learn new things.
