Time’s Top Medical Breakthroughs of 2011
Here is Time Magazine's list of the top 10 medical breakthroughs of 2011.
1. Scientists Use Cloning to Create Stem Cells
"The process is promising because it can potentially yield stem cells — which may one day treat diseases such as spinal cord injury and Parkinson's — that not only match their donor, but also obviate the need for an embryo."
2. A First-Ever Malaria Vaccine
"there has never been a vaccine against a human parasite before, or against malaria, which infects millions of children each year."
3. HIV Treatment As Prevention
"The treatment of HIV has come a long way, thanks to antiretroviral (ARV) drugs that can lower levels of the virus in the body, keeping people healthy and reducing the risk of HIV transmission."
4. The Food Pyramid Becomes a Plate
"This year's update, released in January, urged people to eat less overall, and specifically recommended that they reduce added sugars, salt and fat; better balance the number of calories they eat with the amount they burn off; eat more vegetable and plant-based foods and seafood; and meet federal recommendations for physical exercise."
5. Body Parts Grown in the Lab
"Scientists are now creating real functioning body parts in the lab — like the urethra..."
6. The Curious Link Between Bacteria and Colon Cancer
"Could colon cancer be caused by bacteria? "
7. Dogs That Can Sniff Out Lung Cancer
"Man's best friend might also be a doctor's newest weapon in detecting cancer."
8. You're as Old as Your Spit Says You Are
"it may now be possible for scientists to glean the age of a dead body from genetic material. Working with saliva samples, the researchers focused on epigenetic changes to DNA."
9. A Death Risk Predictor?
"Researchers at Uppsala University in Sweden reported in August that a simple blood test may be able to predict who is most likely to die of heart disease or cancer."
