Maya Bourgeois 10/26/14 09/08/14 “Notch1 and osteoblasts play role in bone cancer initiation” Baylor College of Medicine Glenna Picton Some molecular and cellular geneticists at the Baylor College of Medicine have discovered that Notch1‚ a gene that can decide cellular fate‚ can cause osteoblasts (cells that lead to bone formation) to become cancerous. They determined this data using a mouse model of osteogenic sarcoma‚ a deadly bone malignancy. Turns out that in mice

Q. A young hiker has been on a long walk. He is now sitting in front of a small campfire‚ drinking a hot cup of soup. It is dark and a frost is beginning to form on his tent. Explain the hiker’s heat gains and losses‚ and what mechanisms would come into effect to keep his temperature at the desired 37ºC.
