Here We Go Again!

Germany’s ROSAT (Roentgen Satellit) Satellite is expected to fall back to the earth at the end of October.  The odds of a fragment of the ROSAT hitting a person, upon making landfall, are worse than that of the UARS satellite: 1 in 2,000.  The UARS odds were 1 in 3,200.

The odds of being struck by a ROSAT because ROSAT was built with heat-resistant mirror structures; much of UARS burned up upon re-entry, meaning only 20-40% of UARS actually reached the Earth’s surface.

Heads Up!

Wondering what came of the falling satellite?  NASA says the 6-ton satellite fell in an ideal spot: 300 miles Northeast of Christmas Island in the Pacific Ocean.  There are claims that some pieces fell into Alberta, Canada, but this remains unconfirmed. 

 The 26 falling pieces of the 1,200lb satellite remnants were not expected to weigh more than 300lbs, individually.   The odds of a person being hurt by the falling pieces were 1-in-3,200, as calculated by NASA.

Planet Hunters

Ever want to try your hand at astronomy?  www.PlanetHunters.org is giving you that opportunity.  Dedicated to finding planets among a sea of stars, Planet Hunters hosts a website where 40,000 users around the world help professional astronomers analyze 150,000 stars’ light in search of an orbiting planet.  The data being analyzed is from NASA’s Kepler mission.  Does the website work? 

Since its launch in March 2009, two exoplanets have been found beyond our solar system.

“Citizen Scientists” on Planet Hunters have currently discovered 1200 candidates, which are then further investigated by astronomers.  So far, two findings have been classified as planet candidates.  Will you be the one to find the next planet candidate?

Breast Cancer Killing Virus

Scientists at Penn State College have found a virus that kills three different types of breast cancer, throughout different stages of cancer development, without causing subsequent disease.  Adeno-associated virus type 2 (AAV2) is regularly contracted by humans, but does not cause disease.  Instead, AAV2 has been shown to constantly kill cancer cells throughout the body. 

The benefit to using AAV2 to kill breast cancer is that AAV2 can tackle the many stages breast cancer goes through.  Normally breast cancer is difficult to treat because the multiple stages are affected by hormones, metastases, drug resistance, and potential toxicities.  AAV2 is able to cut through all these barriers and go straight to the cancer cells.  In laboratory tests, 100% of the cancer cells were destroyed by the virus within seven days.  Scientists are now analyzing the virus’ pathology to develop medications to replicate this for clinical use.

Heart-attack Proof

Dr. Caldwell Esselstyn Jr has noticed, in his cancer research, that certain cultures do not suffer from the number one killer in the Western world: heart disease.  Studying the diets of these cultures, Dr. Esselstyn has determined that his dietary prescription can “heart attack proof” your body.  This diet consists of consuming no: meat, eggs, diary, or added oils. 

Dr. Esselstyn’s plant-based diet has been known to help patients, deemed “too sick for surgery,” recover.  Many of Esselstyn’s patients credit the diet for saving their lives.  Esselstyn recommends not waiting until a problem presents to start the diet, as most often the first sign of heart disease is sudden death.

Look Up, Look Down, All Around; Hey, Satellite!

A satellite orbiting in space is quickly making its decent to Earth this very moment.  The path Upper Atmosphere Research Satellite (UARS) will be falling in is unclear at this point; however, scientists have determined it is unlikely it will land in North America.  Because 70% of the Earth’s surface is water, scientists believe it will likely land in water, or an unpopulated area.  

Most of the satellite’s aluminum structure is expected to burn up upon its descent.  26 pieces are expected to remain intact, ranging between 10 to hundreds of pounds.  The pieces also will not be falling at an intense rate of speed, such as that which it is capable of in orbit.  Erring on the side of caution, the FAA issued a warning to pilots about the falling debris, requesting a report of any falling debris sighted.

Putting the "M" in STEM

Slews of students throughout the US are struggling to meet state standardized math tests.  With classes such as algebra, geometry, and calculus, students are having to find ways to learn mathematical concepts without an understanding of real-world application.  Even worse, many students are being forced to learn math skills they may never use, while important math skills go largely untaught. 

Many are proposing a reformation of math classes in the US.  Classes such as finance, data, and basic engineering classes are thought to better serve students in the long run, as opposed to calculus.  The concern is not with the value of current math classes, but rather the practical application.  Some believe that this reformation of math classes could bring the US to prosper through teaching practical math, instead of traditional math.
