This week on Txchnologist, we explored inventions and discoveries that have the potential to improve myriad lives. First, our correspondent talked to researchers who have engineered growth factors that speed the wound-healing process.
The quest to design better water filters continues. MIT researchers have created an efficient nanofilter by poking tiny holes in atom-thick graphene. Their results appear to be dramatically better than the traditional carbon water filters available on the market.
This week we also learned about new generators that produce energy from the smallest motions. The generator harvests the same kind of static electricity that you produce by shuffling across the carpet.
Our hearts melted when we watched 12-year-old Peyton Robertson describe his Discovery Education 3M Young Scientist Education award-winning experiment. He used the scientific method come up with an innovative solution defending against floods.
Now we’re bringing you the news and trends we’ve been following this week in the world of science, technology and innovation.
When the body gets wounded, it naturally generates molecules known as growth factors that are critical to helping it heal. Now researchers have engineered new versions of these growth factors that can help repair wounds and bone defects in mice faster and more effectively than their own natural versions.
Scientists have long sought to use growth factors to help the body regenerate. These chemicals have led to therapies that help promote new blood vessel and bone formation.
However, low healthy doses of growth factors are often not as useful as one might like, while larger doses “have the potential to be harmful, by generating tissue like bone where you don’t want bone or by inducing cancer,” says Jeffrey Hubbell, a bioengineer at the Swiss Federal Polytechnic School of Lausanne. “Growth factors have gotten, as a class, a bit of a black eye.”
The second most popular beverage in the world, after water, is believed to be tea.
There are different kinds of tea, but green tea carries with it a slew of promised health benefits. And now, scientists have made a new discovery within a simple cup of green tea.
