Plants do complex arithmetic calculations to make sure they have enough food to get them through the night, new research published in journal eLife shows. Scientists at Britain's John Innes Centre said plants adjust their rate of starch consumption to prevent starvation during the night when they are unable to feed themselves with energy from the sun. They can even compensate for an unexpected early night. "This is the first concrete example in a fundamental biological process of such a sophisticated arithmetic calculation," mathematical modeler Martin Howard of John Innes Centre (JIC) said. During the night, mechanisms inside the leaf measure the size of the starch store and estimate the length of time until dawn...

If I had a garden I think I might want to plant of few of these around the perimeter. BBC News reports on the rare Chilean sheep killer, Puya chilensis:

A South American plant with a 10ft (3m) tall flower spike is about to bloom in a Surrey glasshouse for the first time since it was planted 15 years ago.
The Royal Horticultural Society (RHS) at Wisley said the Puya chilensis, a native of Chile, would bloom in the next few days and last about a week.
In the Andes it uses its sharp spines to snare and trap sheep and other animals, which slowly starve to death.
The animals then decay at the base of the plant, acting as a fertiliser.
The RHS feeds its specimen on liquid fertiliser.
The gardening charity said very few specimens of Puya chilensis were known to have flowered in the UK.
The National Botanic Garden of Wales waited 11 years for its plant to bloom, though clumps bloom every April in the open on Tresco in the Isles of Scilly.

A team of international scientists report today that they have sequenced and annotated the genome of the sacred lotus (Nelumbo nucifera). The research was co-led by Ray Ming, a plant biology professor at University of Illinois’ Institute for Genomic Biology; Jane Shen-Miller, a plant biology professor at UCLA; and Shaohua Li, director of the Wuhan Botanical Garden at the Chinese Academy of Sciences. The team have sequenced nearly 90 percent of the plant’s 27,000 genes.
The sacred lotus has the ability to repair genetic defects, and may hold a key to the secrets of aging; the seeds of the lotus can survive up to 1,300 years. The sacred lotus is known from the geologic record as early as 135 million years ago. The plant has been grown in China for at least the last 4,000 years, and has long been used there for food and medicine.
“Plants substitute biosynthesis for behavior”, employing biochemical messaging as a means of interacting with their environment on a level we don’t even fully understand, yet we are constantly immersed in this sea of molecular communication.. Its been hypothesized that plant psychedelics are messenger molecules to mammals that naturally raise awareness at critical junctures in order to impart information vital to maintaining the continuity of the all life in biosphere…But how do plants communicate with each other besides the thick matrix of pheromonal activity?

Plants have scientifically been show to draw alternative sources of energy from other plants. Plants influence each other in many ways and they communicate through “nanomechanical oscillations” vibrations on the tiniest atomic or molecular scale or as close as you can get to telepathic communication.
Members of Professor Dr. Olaf Kruse’s biological research team have previously shown that green algae not only engages in photosynthesis, but also has an alternative source of energy: it can draw it from other plants.
This is so sci-fi it’s positively scary! The home brewing school of science has turned to crowdfunding platform Kickstarter to fund the creation of genetically engineered glow-in-the-dark trees, reports Andrew Pollack for the New York Times:

Hoping to give new meaning to the term “natural light,” a small group of biotechnology hobbyists and entrepreneurs has started a project to develop plants that glow, potentially leading the way for trees that can replace electric streetlamps and potted flowers luminous enough to read by.
The project, which will use a sophisticated form of genetic engineering called synthetic biology, is attracting attention not only for its audacious goal, but for how it is being carried out.
Rather than being the work of a corporation or an academic laboratory, it will be done by a small group of hobbyist scientists in one of the growing number of communal laboratories springing up around the nation as biotechnology becomes cheap enough to give rise to a do-it-yourself movement.

Israeli scientists have cultivated a cannabis plant that doesn’t get people stoned in a development that may help those smoking marijuana for medical purposes, a newspaper said on Wednesday.
According to the Maariv daily, the new cannabis looks, smells and even tastes the same, but does not induce any of the feelings normally associated with smoking marijuana that are brought on by the substance THC, or tetrahydrocannabinol.
According to Maariv, Tikkun Olam sought to neutralise the effect of the THC and to increase the effect of another substance called CBD, or cannabidiol, which has been shown to help diabetics and to ease various psychiatric disorders.
Not only does it leave users stone-cold sober, it also doesn’t induce the munchies, the hunger pangs that the drug’s smokers generally suffer. Despite the innovation, it is unlikely to have any impact on Israeli law, which outlaws the use of marijuana as illegal except for medical purposes….
“As the races of man speak in different languages so do the varieties of plants manifest their voices in different ways. They seem to be able to hear and understand us. For the time being, however, we must listen to them through our machines. One day, those machines may be unnecessary.”
Our senses provide us with only a small slice of the beauty occurring in the natural world around us. The Data Garden Quartet is music generated by living plants:

Data Garden presents a live exhibition recording of Quartet, the first plant-generated audio composition at the Philadelphia Museum of Art.
The electronic impulses of four plants, interpreted by humans with the help of computers, has been employed to organize sound into beauty perceivable by the human ear. While the means of producing this beauty can be described in technical terms, the natural creative force generating this experience is less apparent.
We all think we know what nature sounds like. It’s birds chirping, wind through trees, thunder echoing through the valley. These are sounds that come from physical phenomena in nature, producing waves perceivable by the human ear: the need to mate, currents of air and water, static electricity. There are other phenomena in our natural environment, however, that produce information which we cannot perceive through our biological senses.
“I believe that the lost secret of human emergence..the undefined catalyst that took a very bright monkey and turned that species into a self-reflecting dreamer..that catalyst has to be sought in these alkaloids in the food chain that were catalyzing higher states of intellectual activity.” — Terence McKenna
Tony Wright and Graham Gynn are authors of Left In The Dark- the book that presents Tony’s research outlining a radical re-interpretation of the current data regarding human evolution and, they contend, our recent degenerated state we call “civilization”. You can read the book for free here. Despite such a young and extreme proposal positive reactions are growing and include such minds as Dennis McKenna, Stanislav Grof, Colin Groves, Michael Winkelman and many others.
There are many mysterious anomalies about human evolution yet to be adequately explained. These include the human brains rapid expansion in size and complexity, why this accelerating expansion suddenly stalled roughly 200,000 years ago and our brains have been shrinking ever since, and why our rare glimpses of genius goes hand in hand with our species wide insanity.… Read the rest
