Yes, Science is awesome, and we are slowly getting smarter.

NYT Story about viroids

The first few paragraphs from the article:

A Tiny Emissary From the Ancient Past

In the early 1920s, farmers in New Jersey noticed their potatoes were shriveling, their leaves becoming deformed. The plants were sick with an illness that came to be known as potato spindle tuber disease. But it took almost five decades for someone to find the cause.

In 1971, Theodor O. Diener, a plant pathologist at the Department of Agriculture, discovered that the culprit is an inconceivably tiny pathogen — one-80th the size of a virus. Dr. Diener called it a viroid.

Since Dr. Diener’s initial discovery, scientists have identified nearly three dozen species of viroids that attack crops from tomatoes to coconuts, as well as flowers such as dahlias and chrysanthemums. In many cases, the only way to stop an outbreak is to destroy all the infected plants. These days many countries require that plants be certified viroid-free before being imported.

But viroids may be much more than agricultural pests. New research suggests that they existed at the earliest stages of life on Earth, enduring in their primitive state for billions of years. These are the pterodactyls of the microbial world — except that they are still very much with us. We just didn’t realize it.

Complex organic molecule found in interstellar space
By Michael Eyre Science reporter

Scientists have found the beginnings of life-bearing chemistry at the centre of the galaxy.

Iso-propyl cyanide has been detected in a star-forming cloud 27,000 light-years from Earth.

Its branched carbon structure is closer to the complex organic molecules of life than any previous finding from interstellar space.

The discovery suggests the building blocks of life may be widespread throughout our galaxy.

Various organic molecules have previously been discovered in interstellar space, but i-propyl cyanide is the first with a branched carbon backbone.

The branched structure is important as it shows that interstellar space could be the origin of more complex branched molecules, such as amino acids, that are necessary for life on Earth.
