DNA Not The Same In Every Cell Of Body

DNA Not The Same In Every Cell Of Body. "...calls into question one of the most basic assumptions of human genetics: that when it comes to DNA, every cell in the body is essentially identical to every other cell... if it turns out that blood and tissue cells do not match genetically, these ambitious and expensive genome-wide association studies may prove to have been essentially flawed from the outset"

Molecular Movies features cell and molecular animations, along with animation tutorials. Animations range from apoptosis, to microtubules, multiple sclerosis, and chromatin packing. A longer, narrated version of DNA visualization is available on Youtube. (via)

Shedding Light on Life

Light makes a comeback. “New technologies — more sophisticated imaging techniques, fluorescent molecules that act as beacons of light in the cell, and the computing power to gather and stitch together multiple images and create videos from high-powered microscopes — make it possible to harness one of light’s key advantages: gentleness. Unlike higher-resolution techniques, light microscopes can image biological structures without killing them or chemically fixing them. At Harvard, the resurgence of light microscopy is making it possible to see structures and events that have never before been seen in the context of living cells and organisms.” Also don't miss the video samples of “in vivo” imagining.

View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons.

No stem cell research

Thou shalt not make scientific progress. "Medical research is poised to make a quantum leap that will benefit sufferers from Alzheimer's, Parkinson's, muscular dystrophy, diabetes and other diseases. But George W. Bush's religious convictions stand in its way."

Scientists in the USA have discovered [NYTimes] a new cell in the eye responsible for resetting the biological clock. Its being called "heretical".. Not every day, Dr. Provencio said, do scientists find a new body function.
