There are analgesics, e.g. opioids that dull the sensation of pain stimulus to the body. Some recreational drugs do contain opiates. For articles, you may want to search (keywords): opioids & electric shock, to find some useful literature.
We already know about echolocation, using the ears to sense objects and space around us (also dolphins, bats, whales and some birds are quite good at this).. But how about using a sensor on our tongue to input visual information. Here is a Scientific American article describing this technology...
In addition to what davenn has described..
I too have experienced this phenomenon. At college when I wired speakers to the kitchen, my source signal (stereo receiver/turntable/CD player) was located in a distant room. When i played jazz or classical music through my speakers, during in the...
The cables do have resistance, so you may think of this as a small resistor. The current is not infinite. For example #24 Ga. wire has a resistance of ~25.5 ohms per 1000ft of cable. So if you connected a constant voltage (e.g. 12V) across 1000ft of this wire, the current is not infinite. It...
As the clock of the season ticks on, i notice each wildflower coming into its own. While mowing the grassy field last week, I am seeing the burnt orange blossoms of devil's paintbrush (aka orange hawkweed, Hieracium aurantiacum) a vivid contrast to the green grass.
(Others have appreciated...
You are right that in the definition of a terminal bud, it occurs at the tip of a stem.
Your teacher is also correct in stating that a terminal bud is absent (does not occur) at the apex of a leaf. Perhaps some past students confused the tip of a leaf with the tip of a stem and she is making...
thank you Lisa. It is great to see you :redface:
I did happen to see a PF chat window on New Year's eve (within an hour of midnite), however i only saw one person logged in, so i gathered, the rest of our PF friends were having a party on another chat somewhere. :oldeyes:
Wishing everyone a Happy and Healthy New Year ! :oldsmile:
( I was looking for the PF Christmas and also New Years Chat, but could not find where you all were :oldconfused:
( Is word of chat activation still posted here in discussion? )
So now these researchers have shown this to be the case, we may ponder the next logical question, is this how life orginaly arrived on Earth and populated our ancient oceans? hmmmm :oldeyes:
I am not aware of specific places in Connecticut where this is done.
However there are online companies that will do this for you. We don't endorse
specific ones. However you can find a listing of such companies that do
DNA testing here.
Also if you watch some of the...
very fine looking brassicas don! :smile: i heard when heads are the size of a chicken egg is time to blanch (tie up leaves) of developing cauliflower. I wonder when did you blanch them? How loose do you tie their leaves? or perhaps you are growing a self-blanching cultivar. :wink:
Hi btb, i am also a musician and was curious to see what you were writing about.
Hearing the audio spectrum varies with each individual. It can deteriorate depending on the
intensity of sounds you have been exposed to throughout your life and also the high end tends to
deteriorate with...
Reading suggestion
There are so many good texts. I found: University Physics by Young and Freedman, to be very useful, in my first three introductory physics classes. :smile: It offers lots of diagrams and they explain concepts in understandable language. It also has many good homework...
welcome & physics-self study
hi tyler,
Welcome to our forum. I see you were treated to our official fish welcome, congratulations :biggrin:
In addition to the references mentioned for physics self study. I would also suggest the Khan Academy free online talks. My link points to...
We had a great garlic crop again this summer, scapes were delicious.. I also stir fry mine up :smile: I just set out new cloves in the garden for next season. With such a warm autumn, planting them by Halloween seemed about right. :wink:
I also dug in some well composted chicken manure...
