Diamond-Based Quantum Devices Shrink MRI to Nanoscale
Diamond-based quantum devices can now make nuclear magnetic resonance measurements on the molecular scale. Work by two independent groups will make it easier to find out the structure of single biological molecules such as proteins without destroying or freezing them.

Injectable Foam Blocks Internal Bleeding on the Battlefield
Despite their best efforts to stabilize abdominal wounds sustained on the battlefield, military first-responders have few options when it comes to stanching internal bleeding caused by, for example, gunshots or explosive fragments. The Defense Advanced Research Projects Agency (DARPA) says it is studying a new type of injectable foam that molds to organs and slows hemorrhaging. This could provide field medics with a way to buy more time for soldiers en route to medical treatment facilities. [More] (Source: Scientific American Topic - Medical Technology)

Controversial Stem Cell Company Moves Treatment out of U.S.
US citizens who had pinned their hopes on a company being able to offer stem-cell treatments close to home will now need to travel a little farther. Celltex Therapeutics of Houston, Texas, stopped treating patients in the United States last year following a warning from regulators. A 25 January e-mail to Celltex customers indicates that the firm will now follow in the footsteps of many other companies offering unproven stem-cell therapies and send its patients abroad for treatment -- but only to Mexico.

Stimulating the Brain with Microscopic Magnets
Imagine if your biggest health problem could be solved with the flip of a switch. Deep-brain stimulation (DBS) offers such a dramatic recovery for a range of neurological illnesses, including Parkinson's disease, epilepsy and major depression. Yet the metal electrodes implanted in the brain are too bulky to tap into intricate neural circuitry with precision and corrode in contact with tissue, so their performance degrades over time. Now neurophysiologists have developed a method of DBS that avoids these problems by using microscopic magnets to stimulate neurons. [More] (Source: Scientific American Topic - Medical Technology)

Syringe Design Change Could Cut HIV Transmission
Sharing syringes is a big no-no. But despite the warnings, needle sharing among injection drug users is still a significant cause for the spread of HIV and other infectious diseases. [More] (Source: Scientific American Topic - Medical Technology)

Genome Donators Can Be Sleuthed Out
Since the first human genome sequence was published, thousands of people have submitted their DNA for scientific analysis. They made these donations anonymously--or so they thought. Now, using publicly available information, researchers found they could figure out the identities of 50 individuals who had loaned their genes to science. Their results, although not the names of the people, are in the journal Science .

Fetal Genome Screening Could Prove Tragic
In a few years you will be able to order a transcript of your entire genetic code for less than $1,000. Adults cannot do much to alter their biological lot, but what if parents could examine their unborn child's genome? Without proper guidance, they might decide to take drastic measures--even to end the pregnancy--based on a misguided reading of the genetic tea leaves.

Skin-Cancer Spotting Apps Miss Their Marks

A Dangerous Game: Some Athletes Risk Untested Stem Cell Treatments
In 2005, at the age of 32, then Los Angeles Angel Bartolo Colón won the American League Cy Young Award for best pitcher, one of professional baseball's top honors. He stumbled through subsequent seasons, however, after a series of rips and strains in the tendons and ligaments of his throwing arm, shoulder and back. In 2009 he all but quit baseball. Desperate to reclaim his career, Colón flew home to the Dominican Republic in 2010 for an experimental procedure not vetted or approved by the U.S. Food and Drug Administration. Doctors centrifuged samples of Colón's bone marrow and fat, skimmed off ...

Researchers Build New Bridges for Nerve Injury
In the January 2013 issue of Scientific American , D. Kacy Cullen and Douglas H. Smith of the University of Pennsylvania reported on their work using stretch-grown axons (the long thin "arm" of a nerve cell) to some day connect prosthetic devices to the peripheral nervous systems of people who had to have part of their arm amputated. There wasn't enough room to talk about it in the article, but there is another way that these "living bridges" could be used to help people with devastating injuries.
