If you believe the creations of science fiction, black holes serve as gateways to other worlds, either distant parts of this universe or other universes entirely. But the reality might be more complicated than that. And outside of the sci-fi realm, dropping into a black hole is a bad idea.

Even so, it turns out that people who enter a black hole would have at least a slight chance of escaping, either back into their own world or to some exotic place. This is because black holes actually bend space itself, and so could bring points that are ordinarily distant from each other much closer together.

An oft-used analogy is the bending of a piece of paper. If you draw a line on the paper, it follows the paper’s shape and the line’s length is unchanged by bending the paper. But if you go through the paper, the end points of the line are much closer to one another. Understanding this requires diving into Einstein’s theory of relativity as applied to gravity.

The digital universe — all the data contained in our computer files, historic archives, movies, photo collections and the exploding volume of digital information collected by businesses and devices worldwide — is expected to hit 44 trillion gigabytes by 2020.

Researchers have developed one of the first complete systems to store digital data in DNA — allowing companies to store data that today would fill a big box store supercenter in a space the size of a sugar cube.

The best kind of science fiction comes to life (well, to a box, technically).

If you trace our evolutionary tree way back to its roots — long before the shedding of gills or the development of opposable thumbs — you will likely find a common ancestor with the amazing ability to regenerate lost body parts.

Researchers have built a running list of the genes that enable regenerating animals to grow back a severed tail or repair damaged tissues. Surprisingly, they have found that genes important for regeneration in these creatures also have counterparts in humans. The key difference might not lie in the genes themselves but in the sequences that regulate how those genes are activated during injury.

A Duke study appearing April 6 in the journal Nature has discovered the presence of these regulatory sequences in zebrafish, a favored model of regeneration research. Called “tissue regeneration enhancer elements” or TREEs, these sequences can turn on genes in injury sites and even be engineered to change the ability of animals to regenerate.

Though the quest to find water on distant planets is the most talked-about way that researchers are looking for extraterrestrial life, one of our best bets at understanding life’s complexities lies with comets, not planets.

In fact, the icy space balls are already known to form amino acids and nucleobases, two key substances needed for life to take root. And now, researchers may have found another necessary ingredient: ribose, the ‘R’ in RNA.

Before we dive into the new discovery, it’s important to understand what life, as we know it, needs to get started, and how we think it may have happened here on Earth. Life on Earth requires three macromolecules: RNA, DNA and proteins. The current understanding is that RNA, or ribonucleic acid, came before DNA on Earth.

I started writing this column while I was in Manila, Philippines for a talk with UnionBank, one of the most innovative banks I’ve ever come across.

Driving across Manila is often a painful experience with far too many cars locking up all possible arterials, and nowhere near enough money to redesign and build the needed infrastructure. But this is not unique to Manila.

As I’ve traveled around the world, I’ve run into equally bad traffic in Istanbul, Rotterdam, Los Angeles, Seoul, Mexico City, San Francisco, Rome, London, Beijing, and Mumbai. In fact there are literally thousands of cities where bad traffic is a way of life.
