Electric plant biology
Some very interesting stuff here, but has it been confirmed?
"In vascular plant biology, electro-osmosis is also used as an alternative or supplemental explanation for the movement of polar liquids via the phloem that differs from the cohesion-tension theory supplied in the mass flow hypothesis and others, such as cytoplasmic streaming.[7] Companion cells are involved in the "cyclic" withdrawal of ions (K + ) from sieve tubes, and their secretion parallel to their position of withdrawal between sieve plates, resulting in polarisation of sieve plate elements alongside potential difference in pressure, and results in polar water molecules and other solutes present moved upward through the phloem.[7][8]
In 2003, St Petersburg University graduates based an experiment on the electro-osmosis hypothesis through the application of direct electric current to 10mm segments of mesocotyls of maize seedlings alongside one-year linden shoots used with normal conducting systems and without vascular bundles; electrolyte solutions present in the tissues moved toward the cathode that was in place, suggesting that electro-osmosis may play a role in solution transport through conductive plant tissues."[9]

Re: Electric plant biology
Prof Gerald Pollack's experiments are on a similar line. He also looks at blood flow having similar properties.

exactly, he explicitly talks about this at (0:58:00), although the whole video is outstanding!cigarshaped wrote:Prof Gerald Pollack's experiments are on a similar line. He also looks at blood flow having similar properties.

Flowers and Bees, they live in an electric universe!
Not sure which category this post belongs to, we have a "human" section, should we have a "life sciences"?
Anyways, here goes...
This science news headline came out recently. Some researchers found that bees can sense the electric field of flowers.
It goes like this: Bees shed their electrons through air friction as they fly around and flap their wings, making them positively charged. Flowers are naturally grounded and hence have a negative charge compared to the bees and compared to the air surrounding them.
Once the bee visits, the charge difference is partially neutralized and hence the bees can even know if the flower has already been visited based on its electric field strength. Researchers also found that the bees can distinguish electric fields created by different types of flowers and petal shapes. I also learned something else from the article, that there is a potential difference in the air, the higher the altitude relative to the ground, the higher the potential... about 100 Volts/meter.
It's quite remarkable, here is a link to the article on national geographic: http://phenomena.nationalgeographic.com ... f-flowers/

fantastic article, makes me want to go outside and test it for myself.

Re: Electric plant biology
!
Yes
our esteemed mods,
or maybe just add the category ~ "Bio-electricity" ~ to The Human Question forum header,
and get the valuable electro-bio database all under one, more easily searchable, rubric ?
?

Re: Electric plant biology
I didn't realize that the flowers and bees thing was so old.
I got it on my science news feeds, assumed it's fresh and new.

Re: Electric plant biology
Spider webs more effective at snaring electrically charged insects:

Electrostatic charges are everywhere, and we propose that this may have driven the evolution of specialized webs,” he said.
Kind regards,Insects easily develop several hundred volts of positive charge from the friction of wings against air molecules or by contacting a charged surface

We have been asking ourselves for many years what molecular components plants use to exchange information among each other and how they sense the changes in electric voltage
---Our model clearly showed that the TCP1 channel is made up of two interconnected, nearly identical protein units each capable of forming a potential voltage sensor
