This gorgeous series of photographs from Mendocino's pot harvest might be a glimpse of that future.

Photographer Mathieu Young took these intimate pictures of a small pot farm at harvest time. We see the whole process, from the harvest in hidden greenhouses to the trimming, sorting, drying, and packaging for shipment. I keep imagining that they are growing lettuce and fruit to share with a small, underground collective of organic farmers who don't want to pay a licensing fee to farm. Or maybe I've just been reading too much Margaret Atwood.

<![CDATA[Researchers Discover the Secrets of Flower Sperm]]> Flowering plants go through a complicated double-fertilization process that involves a lot of sperm. But until today, researchers hadn't fully understood the genetic mechanism behind plant sperm production (pictured) and how flowers have sex.

Plant biologists at the University of Leicester researched the unusual plant reproduction system, trying to figure out how it works on the genetic level, and published their findings today in PLoS Genetics. According to David Twell, one of the co-authors of the paper:

Flowering plants, unlike animals require not one, but two sperm cells for successful fertilisation. One sperm cell to join with the egg cell to produce the embryo and the other to join with the central cell to produce the nutrient-rich endosperm tissue inside the seed. A mystery in this 'double fertilisation' process was how each single pollen grain could produce the pair of sperm cells needed for fertility and seed production.

We now report the discovery of a dual role for DUO1, a regulatory gene required for plant sperm cell production. We show that the DUO1 gene is required to promote the division of sperm precursor cells, while at the same time promoting their specialised function as sperm cells. It effectively switches on the essence of male.

So what's the upside for you? First of all, it could help plant-growers understand gene flow in their crops. On a more pure research level, this discovery might help evolutionary biologists better understand what makes flowering plants such a successful form of life; and it may even shed light on boring old single-fertilization reproduction that we animals engage in.

But I think we all know what's really going on here. This lab is trying to prevent the spread of Triffids across the Earth by messing up their reproductive systems. Thanks, Leicester plant biogeeks, for saving the world by studying plant sperm. Those of us who don't fancy being eaten by giant plants from space totally appreciate it.

<![CDATA[Don't Eat the Glowing Mushrooms]]> You might already know about the glowing mushrooms of Japan. Every spring, the rains cause bioluminescent fungi to peep out from tree trunks and forest floors. For years scientists believed that these rare mushrooms grew nowhere else in the world. But now the glowers turn out to thrive in the forests of Brazil, too. Four new species like these, pictured, have been discovered there since 2002.

According to National Geographic:

The mushrooms are part of the genus Mycena, a group that includes about 500 species worldwide. Of these only 33 are known to be bioluminescent - capable of producing light through a chemical reaction.

In Japan, you can go on a nighttime tour in early summer to see the glowers. Generally, however, researchers prefer that crowds leave the green guys alone. They're rare, and tend to prefer areas with very little human habitation.
