Baruch Blumberg, Nobel winner and recent speaker at McCall, dies at 85
Baruch Blumberg, 85, a Philadelphia researcher who won the Nobel Prize in medicine in 1976 for his work on hepatitis B, died Tuesday in Moffett Field, Calif.
He collapsed after giving a speech at the International Lunar Research Park Exploratory Workshop being held at the NASA Ames Research Center, said his daughter Anne Blumberg. Her father, who was the director of the NASA Astrobiology Institute from 1999 to 2002, had been in good health and died of an apparent heart attack, according to NASA. "He was as busy last week as he was his whole life," his daughter said.
Dr. Blumberg, who had worked at Fox Chase Cancer Center since 1964 and still maintained an office there, discovered the hepatitis B virus and later helped develop a vaccine against it. The vaccine, which is now made in a different way, was approved by the FDA in 1981. Dr. Blumberg's work also allowed blood banks to screen for hepatitis B, a blood-borne virus. It can cause serious liver disease, liver cancer, and death.
"His vaccine and his research have saved hundreds of thousands of lives," said Ann Skalka, basic science director emerita at Fox Chase in Northeast Philadelphia.
Friends and family described him as an unusually curious, outgoing, funny, affable, and adventurous man who traveled widely and loved walking in his beloved Philadelphia. He had given up active research in recent years but still had the title of senior adviser to the president and CEO at Fox Chase and university professor at the University of Pennsylvania. At NASA, he had focused his formidable intellect on studying the possibility of life in space.
Dr. Blumberg, who was known as Barry, was also the current president of the American Philosophical Society, a Philadelphia-based learned society founded by Benjamin Franklin.
Dr. Blumberg traveled the world for his research and was particularly interested in Lewis and Clark's journals, which were part of the society's collection. He started a Lewis and Clark grant program to help young scholars do field research, Annie Westcott, director of meetings for the group, said.

Supermoon Astronomy Photographs
Supermoon
From Wikipedia, the free encyclopedia
A perigee-syzygy of the Earth-Moon-Sun system or "supermoon" is a full or new moon that coincides with a close approach by the Moon to the Earth. The Moon's distance varies each month between approximately 357,000 kilometers (222,000 mi) and 406,000 km (252,000 mi) due to its elliptical orbit around the Earth (distances given are center-to-center).[1][2][3]

Concentration Maze Game
Instructions:
1) Take your Heart Rate by feeling your pulse on your wrist.
2) Count how many beats in 30 seconds then multiply by 2 to get your beats per minute.
3) Then play the concentration game and get to level 5.
4) When you get to level five take your heart rate again.
5) Leave your Name and your heart rate before the test and after the test as a comment to this blog post.
How To Measure Your Pulse
Taking your pulse is easy. It requires no special equipment, however, a watch with a second hand or digital second counter is very helpful.
1. Turn the palm side of your hand facing up.
2. Place your index and middle fingers of your opposite hand on your wrist, approximately 1 inch below the base of your hand.
3. Press your fingers down in the grove between your middle tendons and your outside bone. You should feel a throbbing - your pulse.
4. Count the number of beats for 10 seconds, then multiply this number by 6. This will give you your heat rate for a minute.
Example:
If you count 12 beats in the span of 10 seconds, multiply 12 X 6 = 72.
This means your Heart Rate or pulse, is 72 (or 72 beats per minute).
Another popular way to measure pulse rate is by measuring it at the neck (carotid pulse). This is especially convenient during exercise. The formula is the same as above, however, when taking the pulse at the neck, place your fingertips gently on one side of your neck, below your jawbone and halfway between your main neck muscles and windpipe.
Taking your pulse upon rising in the morning, or after sitting without activity for about 10 minutes, is know as your Resting Heart Rate.

How to Cite Your Sources in Your Bibliography
Many of you are asking how to cite your 5 (at least) sources for your Bibliography. The link below has the format that is preferred (APA) and instructions for how to fill properly show where you got your information.
How to Format Your Bibliography
Remember that of your 5 sources 1 has to be something other than a website. There are many sources of informative texts that would relate to your topic in the school Cybrary or at your local branch of the Phila Public Library.
