Artificial intelligence could dramatically improve the economy and aspects of everyday life, but we need to invent ways to make sure everyone benefits.

Among bacteria’s many attributes, perhaps one of its most overlooked yet important ones is its ability to propel itself via flagellum, a unique appendage hanging off its end. This mechanism is a perfect example of a naturally occurring, biological wheel.

Now, for the first time, scientists were able to take a high resolution, 3D look at these wheels at work, using an electron microscope. Their work was published online yesterday in the journal, PNAS.

A flagella is like a tiny tail at the end of the bacteria, allowing it to move through various mediums. It generates torque (that’s twisting force) from stators, a ring of structures around the motor part of the organ. These act as the wheel providing the power.

Bad news for anyone who thinks Earth-mass planets must automatically harbor life.

New study says nearby earth-mass planet Proxima Centauri b may not be habitable after all. The implications for astrobiology aren’t good.

Elon Musk shared his thoughts on the future of jobs and the government’s role in a rapidly changing society.

Here’s my official announcement/OpEd article via Newsweek for running for California Governor as a Libertarian. Thanks for reading it!

Futurist Zoltan Istvan believes California could become the world’s largest economy.

It tells us something important about cancer.

A mysterious cell process named anastasis (Greek for “rising to life”) challenges our idea of life being a linear march towards death, and suggests that cell death can actually be reversed under certain conditions—essentially allowing cells to un-die.

Even as the cell is shrivelling up in response to radiation, toxins, or other stresses, it can in some cases undo the dying process and repair itself if the stress is taken away before the cell is completely gone, said cell biologist Denise Montell of the University of California, Santa Barbara.

You’ll never hear “are we there yet” again.

Thanks to 3D printing, scientists can now recreate any organ in the human body.
