Mosquitoes

According to CNN writer Jen Christensen, for the first time, scientists found a possible genetic reason why some of us are mosquito magnets, according to  research built on earlier studies that show a person’s body odor might be a part in who gets bitten more.  Earlier studies have found people with a certain type and volume of bacteria that naturally occurs on skin might make people more of a target.  Same with people with Type O blood, that is associated to a specific odor marker in sweat.  Pregnant women sweat more because pregnancy increases their body temperature, so they are bitten more frequently.  The same has been shown with people who weigh more.

Knowing this will not keep you safe from mosquitoes this summer, scientists need conduct more research.  Researchers could find a way to neutralize the specific odor, if that is what the mosquitoes like. This could signify fewer mosquito bites, and “fewer cases of yellow fever and dengue since these particular bugs are often the carriers of these viruses.”

Wear the bug repellant that is on the market any time you go outside.  The Centers for Disease Control and Prevention said to use products that have one of four active ingredients. Check the label for “DEET, picaridin, IR3535 and/or lemon eucalyptus and para-methane-diol products. These products are effective, and they are registered with the EPA.”  This signifies that the chemical will harm only the mosquitoes.  Wearing shirts with long sleeves and long pants if you can handle it in the heat of summer is recommended.  Mosquitoes are less likely to bite what they cannot get to.  Hopefully, one day a treatment will be made to fix this problem.

Sitting Can Cause Death

According to CNN writer Jen Christensen, one of your favorite leisure’s may be killing you.  Our modern world is made to keep us sitting down.  When sit when we drive, when we work at an office, watch TV, etc.

A new study that is being done at the Annals of Internal Medicine found that this kind of inactive behavior increases our likelihood of getting a disease or condition that will kill us prematurely, even if we exercise.

Researchers from Toronto came to this conclusion after analyzing 47 studies of this behavior.  They “adjusted their data to incorporate the amount someone exercises and found that the sitting we typically do in a day still outweighs the benefit we get from exercise.”  The more you exercise, the lower the harmful effects of inactive behavior.

The studies showed inactive behavior can “lead to death from cardiovascular issues and cancer as well as cause chronic conditions such as Type 2 diabetes.”  According to the World Health Organization, physical inactivity has been recognized as the “fourth-leading risk factor for death” around the world.  Prolonged sitting (sitting for 8-12 hours or more a day) increases your risk of acquiring type 2 diabetes by 90%.

The study authors did make some easy suggestions to help sit less. One is to be conscious of how often and long you are sitting.  That way, you can make a goal of decreasing that number slightly each week.  At work, you could try a standing desk or make a routine to stand up or walk around for one to three minutes once every half an hour.  If you watch TV at night, do not zoom ahead.  During the commercials, you can walk around, stand up, or do a light exercise during the show break.  For all situations involving a screen, going away for a couple minutes can also help ease your eyes from staring at the screen and refocus your thoughts.

Tornado Facts

According to the CNN Library, tornadoes are funnel-shaped clouds that develop under thunderclouds and have rapidly rotating air.  Most tornadoes develop from severe thunderstorms. Hurricanes can also create tornadoes.  Tornado winds can pass 300 miles (480 kilometers) per hour.  Tornadoes can lift cars and mobile homes into the air.  The damage path of a tornado is typically less than 1,600 feet wide.  Most tornadoes travel at less than 35 miles per hour.  Most tornadoes last about a few minutes.  The most destructive and deadly tornadoes develop from supercells, which are “rotating thunderstorms with a well-defined radar circulation called a mesocyclone.”  Supercells can create damaging hail, severe winds, frequent lightning, and flash floods.  A tornado above a body of water is called a “waterspout.”

The United States has the greatest number of tornado incidences in the world with an average of 1,000 tornadoes recorded each year.  According to the National Weather Service there were “over 47 tornado-related deaths in the United States.”  Most of the tornadoes in the United States develop in Tornado Alley, which extends through the Midwest and the South.  Tornadoes typically occur “during the spring and early summer, most often in the late afternoon and early evening.”

A tornado watch is made by the National Weather Service when atmospheric conditions promote the forming of tornadoes.  A tornado warning is made when Doppler radar identifies a mesocyclone in a thunderstorm, or when a funnel cloud has been seen.  A tornado emergency is a more severe alert extended from a tornado warning signifying a large tornado is moving into a heavily populated area.  Substantial widespread damage and fatalities are probable.  The term was created by forecasters in May 1999 and is used rarely.

According to the CNN Library, the fujita scale is used to estimate the wind speed of a tornado by the damage the tornado causes.  EF0 is the weakest point on the Enhanced Fujita Scale and EF5 is the strongest.  An EF5 tornado can rip a house off its foundation.

Category EF1 wind speed is between 86 and 110 miles per hour and creates moderate damage.  Peels the surfaces off roofs; mobile homes ripped off foundations or overturned and moving cars are pushed off roads.

Category EF2 wind speed: between 111 and 135 miles per hour and creates considerable damage.  Roofs torn off framed houses; mobile homes destroyed; boxcars turned over; large trees snapped or lifted; light-object missiles created; and cars lifted off the ground.

Category EF3 wind speed: between 136 and 165 miles per hour creating severe damage.  Roofs and some walls torn off houses; trains turned over; most trees lifted; heavy cars lifted off the ground and thrown.

Category EF4 wind speed: between 166 and 200 miles per hours creating devastating damage.  Some moderate frame houses lifted; structures with weak foundations blown away some distance; cars thrown; and large missiles generated.

Category EF5 wind speed: 200 plus miles per hour creating incredible damage.  Strong framed houses lifted off foundations and swept away; automobile-sized missiles fly through the air in excess of 100 meters; and trees destroyed.
