Scientists have successfully created the world's first laser pacemaker. They are able to control a living creature's heart with a laser beam, making it a leap towards technology that could prevent serious heart defects.
The procedure uses pulses of light to pace the heart of a two day old quail embryo. The research team at Case Western Reserve University, stuck a small laser about a millimeter away from the embryo's heart, and the resulting light pulses created a temperature gradient that spurred muscle contractions.
It shows that lasers can regulate an organism's heartbeat without damaging tissue. Someday, this could lead to scientists creating pacemakers that don't require invasive surgery or heart weakening electrodes. [Nature Photonics via PopSci]
A college education is important. But there have been cases where a handful of people have made it without a degree. That said, college isn't for everyone. While graduates are more likely to get hired compared to someone without higher education, many of the technology companies we rely on today were started by dropouts. Read more
The drawback of having a cast this cool looking? No one is going to be able to sign on it. But who cares! You want those broken bones to heal. And heal fast! Deniz Karasahin designed a custom cast that comes with an ultrasound device to speed up bone healing. Read more
A new report coming from New Scientist talks about a company called GenePeeks. They use its software to take genome sequences of both parents to produce "10,000 simulated pairings". Which means in the future, you'll get the predict what your kids would look like, along with a slew of other things. Read more
