Networks of Genome Data Will Transform Medicine Breakthrough Technical standards that let DNA databases communicate. Why It Matters Your medical treatment could benefit from the experiences of millions of others. Key Players Global Alliance for Genomics and Health Google Personal Genome Project The Story of Cholera Cholera is caused by Vibrio cholerae, a Gram negative, curved rod-shaped bacterium. For more information about its taxonomy and structure, go to the National Institutes of Health or the World Health Organization. Cholera caused discord when an outbreak in Haiti after the 2010 earthquake killed more than 8,000 citizens. The country had not dealt with a cholera epidemic in a century, according to a Foreign Affairs article about the situation, "Peace and Pestilence," which also described the outrage that spread when investigators discovered the origins of the pathogen in Haiti. Nepalese peacekeepers from the United Nations had been disposing of human waste improperly--sending cholera into a tributary feeding the largest river in the nation. The disease wreaked havoc in London in the mid-1800s, where outbreaks caused more than 50,000 deaths.

Scientists have invented a brain decoder that could read your inner thoughts Scientists have figured out how to read the words of our inner monologue, a finding that could help people who cannot physically speak to communicate with the world.

We're More than Stardust — We're Made of the Big Bang Itself Transcript Anna Frebel: The work of stellar archaeology really goes to the heart of the "we are stardust" and "we are children of the stars" statement. You’ve probably heard it all but what does it actually mean? We are mostly made all humans and all life forms that we know of are made mostly of carbon and a bunch of other elements but in much lesser quantities. Where does this carbon come from?

How a few scientists transformed the way we think about disease - Tien Nguyen Dr. John Snow is considered as one of the fathers of epidemiology. He became interested in the cause of cholera after treating many patients afflicted with the disease. Scientist creates lifelike cells out of metal Scientists trying to create artificial life generally work under the assumption that life must be carbon-based, but what if a living thing could be made from another element? One British researcher may have proven that theory, potentially rewriting the book of life. Lee Cronin of the University of Glasgow has created lifelike cells from metal — a feat few believed feasible.

Monkey teeth hint at a miraculous marine migration to North America Scientists have long thought that monkeys first ventured from South America into North America no earlier than about 4 million years ago, when the two continents merged. But seven teeth unearthed in Panama may change that story. These monkey teeth were discovered encased in 21-million-year-old rocks. This suggests that the primates accomplished the impossible: they crossed the more than 100 miles of ocean that separated South America from North America at the time.

This TED Talk Shows How Mucus Is There To Keep Us Healthy When you say mucus, most people automatically think of the stuff that comes out of a person’s nose when they're sick. That is true, however — as disgusting as mucus may seem — it is actually keeping us healthy. In a recent TED Talk, speaker Katharina Ribbeck explains the various ways our mucus is actually looking out for us. Our body produces more than a liter of mucus per day.
