So, Dr. Craig Venter, the genius who first sequenced the human genome, is at it again. This time, he has created artificial life. Does the man ever sleep? Anyhow, here is the latest installment in my innovation-that-you-might-have-missed series. Included you will find news on the 3D-printing of a human heart, pain management, a new electric battery breakthrough and my personal favorite—sideways elevators!
Researchers Now Capable Of 3D-Printing a Human Heart Using Organic Materials
A recent breakthrough in bio-printing technology may allow for the creation of human hearts. A research team at Carnegie Mellon used a consumer printer to create a heart out of organic material. While 3D-printing has previously been used to solve a lot of different problems, it had, until now, built things out of plastic and metal—inorganic materials that don’t necessarily adapt well to the human body. Hopefully, further progress of this sort in bio-printing tech will revolutionize the treatment of tissue damage and organ failure.
New Foam Batteries Promise Faster Charging, Higher Capacity
Despite billions of dollars spent on investment, innovation in batteries has lagged relative to other technologies. However, a growing number of researchers are looking at three-dimensional batteries that tend to have porous, sponge-like structures, as opposed to the traditional “2-D” form (i.e., thin layers of metal in a liquid electrolyte solution inside a box). A recent startup, called Prieto Battery, claims to have succeeded in producing a 3-D battery that would be cheaper to make, faster to charge, safer, smaller, and less environmentally toxic than conventional batteries. Prieto’s innovation increases the battery surface area, thereby reducing the distance that the ions have to travel, thus increasing both power and energy density. While the first applications of these new batteries will be limited to small wearable systems and consumer electronics, they could eventually spread to cars, and one day, even grid-scale storage systems.
Scientists Discover How to “Turn Off” Pain
Researchers have discovered that people who suffer from chronic pain (e.g., arthritis) develop more receptors that respond to opiate pain relief. Having extra receptors makes the body more resistant to pain—both by using our bodies’ natural painkillers, endorphins, and through prescribed opiates such as morphine. Put differently, people who regularly underwent physical pain, such as arthritis sufferers as well as those who exercised regularly, were more resistant to pain due to their brains’ increased opiate receptor density. Increasing the receptor density may, therefore, hold the key to more effective pain relief treatment.
