We round up the latest medical advances and emerging breakthroughs in science and technology.
United States: Improve Your Eyesight with an App
November 2012 — Hate reading glasses? A new app called GlassesOff might let you drop them by training your brain to better interpret that fuzzy print in the newspaper. Users play quick games that employ special wavy images to stimulate connections in the visual part of the brain. In a recent small study, people could read the paper without reading glasses after three months of training (15 minutes three times a week), and their reading speed increased by 17 words per minute. The developers plan to launch the app for iPhones and iPads by early 2013, followed by an Android version.

United States: Calculate Your Heart Rate with Your Face
November 2012 —Cardiio, a new app for iPhone and iPad developed by Harvard and MIT researchers, can calculate heart rate by merely gazing at your face. It uses your device’s camera to measure tiny changes in blood flow in your face that occur when your heart beats. Simply line up your image with the displayed target, and the app reports your heart rate in seconds; when used in a well-lit environment, it’s accurate to within three beats per minute of devices used by doctors. You can track heart rate over time and get info about your fitness level and estimated life expectancy. The app is available now on iTunes.

United States: ID Skin Cancer with Your iPhone
University of Michigan doctors helped develop the UMSkinCheck app, which lets you do a skin self-exam at home using an iPhone or iPad. The app guides you through 23 head-to-toe locations. It has you snap photos of suspicious spots with the device’s camera, then saves the images so you can reference them against future changes or show them to your doctor. There’s also a tool to track worrisome spots, get reminders for your next self-check, and calculate your skin cancer risk. The free app is available now on iTunes; an Android version will follow soon.

Italy: Quicker Stroke Recovery
October 2012 —When a stroke strikes the right side of the brain, it can disrupt communication with the brain’s left side, sometimes making people completely unaware of objects located to the left side of their bodies. In a recent small study, patients who received just two weeks of a special type of magnetic therapy saw a 22 percent increase in their ability to react to their environment on both sides of their body compared with those who received standard therapy. The researchers hope to test other types of brain stimulation soon.

Austria: Parkinson’s Vaccine
A new inoculation may be the first to stop the debilitating neurological disease by targeting its cause in the brain. Researchers think that most cases of Parkinson’s develop when a certain protein, called alpha-synuclein, accumulates in the brain and injures and eventually kills nerve cells, leading to the disease’s well-known tremors and other symptoms. The vaccine teaches the immune system to produce antibodies against the protein. The vaccine’s developer, AFFiRiS, recently started its first human trial to test for safety.

United States: A Smart Pacifier for Premature Babies
October 2012 —Babies born early often don’t know how to suck, a crucial skill for feeding. The Pacifier Activated Lullaby helps by utilizing their innate love of music. When babies suck correctly, they hear a soothing lullaby to encourage them. Studies show that babies who use the pacifier gain weight faster and leave the hospital on average five days earlier than those who don’t. The FDA-approved binky is currently designed for hospital use only; the next generation will help babies at home.

Germany: Smarter Hip Implant
September 2012 — Many hip implants are metal, which requires extra care during surgical implantation and can cause problems if parts grind against each other and release particles that may cause inflammation and damage organs. Now researchers have developed a metal-free alternative, a special blend of plastics. The pins that hold the two pieces in place are made of bone mineral (not metal or cement). In early tests, a robot simulated walking up and down stairs; researchers hope to market the hip in Europe within five years.

Japan: Stem Cell Cure for Baldness
September 2012 — Scientists have grown hair on bald mice using stem cells collected near the mice's whiskers (so embryos aren't necessary). The hair strands grew back even after being plucked and were able to rise into goose bumps as normal hair does. If it proves successful in humans, the therapy could replace current hair-loss treatments (such as hair transplantation surgery and topical medicine like Rogaine) for male-pattern baldness. The researchers hope to start clinical trials in humans within three to five years.

United States: A Device That Predicts Heart Attacks
September 2012 — A silver-dollar-size implant that is placed under the skin near the left shoulder, the AngelMed Guardian may help ID a heart attack quickly by monitoring the heart's electrical activity for unusual patterns, potentially before the wearer notices any symptoms. If the implant detects a problem, it will vibrate, and a portable pager will sound an alarm and flash a warning light. It's approved for sale in Brazil and Europe, and the manufacturer will seek FDA approval here within a year.

Japan: Clever Use of Bad Breath
July/August 2012 — Nippon Dental University researchers found that dental pulp—soft tissue inside teeth that’s removed during root canals—has up to 80 times as many stem cells as previously thought. Even better, hydrogen sulfide, the chemical that causes the rotten-egg smell in bad breath, helps them develop into liver stem cells. Scientists hope that extracted wisdom teeth (or baby teeth saved from childhood) might be used to heal livers damaged
from cirrhosis and the hepatitis C virus.
