Tadpole limb regeneration, human tissue regeneration?
Researchers have identified the electrical switch that turns on a tadpole’s regeneration system so it can grow a new tail or leg. Someday, a detailed understanding of this phenomena could possibly lead to a way to stimulate human tissue regeneration. Michael Levin and his colleagues at the Forsyth Center for Regenerative and Developmental Biology in Boston report that a molecular pump that moves protons across the cell membrane, generating a current, is the “master control to initiate the regeneration response.” From News@Nature:
Researchers have known for decades that an electrical current is created at the site of regenerating limbs. Furthermore, applying an external current speeds up the regeneration process, and drugs that block the current prevent regeneration. The electrical signals help to tell cells what type to grow into, how fast to grow, and where to position themselves in the new limb…
…The complex networks needed to construct a complicated organ or appendage are already genetically encoded in all of our (human) cells (too) � we needed them to develop those organs in the first place. “The question is: how do you turn them back on?” Levin says. “When you know the language that these cells use to tell each other what to do, you’re a short step away from getting them to do that after an injury.”

Yes, I know. But it wasnt my fault.
So… My site was down for a couple weeks. Not my fault. Normally when it goes down, the host is back up in a couple days max, so i waited per the norm for things to go back to normal. after 3 weeks I said “Ok, time to move it”, which I did. Sadly, I also had my linux box freak on me and I lost my local backup of the site. So I’ll be starting again from scratch until I can get access to my previous host.
Which means, I’m forced to pick a new site style for now. I was thinking of doing it, but I guess I’m forced to now. Oh well.

Biodiesel from liposuctioned human ass-fat powers race boat

The boat featured in the video runs on a mixture of fuel from various sources — 4 gallons of the stuff was produced from liposuctioned butt blubber (a hundred grams of that came from the captain’s own backside). Welp, there’s a renewable fuel source America has plenty of. Here’s a blog post with more info about EarthRace.

Disney Princess wedding dresses
Disney is launching a line of $1,100 – $2,900 “Princess” wedding dresses. Talk about life-cycle marketing — from tiny costume dresses you can put your toddler in all the way up to the wedding gown. If you are looking for other beautiful wedding dresses then go to Frox of Falkirk. All that’s missing is a burial tiara and sceptre to take to your grave.
Parks and Resorts Chairman Jay Rasulo said he expected the dresses to be a hit among brides to be, especially given the increasing popularity of weddings at Walt Disney World, the site of about 2,000 nuptials each year.
“If you do 2,000 weddings a year, think of all the people who say, ‘I can’t, I have to get married in my hometown, my own church,’ but they certainly may still have that princess dream as part of it,” Rasulo said.

Bash For Loop Examples
How do I use bash for loop to repeat certain task under Linux / UNIX operating system? How do I set infinite loops using for statement? How do I use three-parameter for loop control expression?
A ‘for loop’ is a bash programming language statement which allows code to be repeatedly executed. A for loop is classified as an iteration statement i.e. it is the repetition of a process within a bash script.
For example, you can run UNIX command or task 5 times or read and process list of files using a for loop. A for loop can be used at a shell prompt or within a shell script itself.
for loop syntax
Numeric ranges for syntax is as follows:
for VARIABLE in 1 2 3 4 5 .. N do command1 command2 commandN done
This type of for loop is characterized by counting. The range is specified by a beginning (#1) and ending number (#5). The for loop executes a sequence of commands for each member in a list of items. A representative example in BASH is as follows to display welcome message 5 times with for loop:
#!/bin/bash for i in 1 2 3 4 5 do echo "Welcome $i times" done
Sometimes you may need to set a step value (allowing one to count by two’s or to count backwards for instance). Latest bash version 3.0+ has inbuilt support for setting up ranges:
#!/bin/bash
for i in {1..5}
do
echo "Welcome $i times"
done
Bash v4.0+ has inbuilt support for setting up a step value using {START..END..INCREMENT} syntax:
#!/bin/bash
echo "Bash version ${BASH_VERSION}..."
for i in {0..10..2}
do
echo "Welcome $i times"
done
Sample outputs:
Bash version 4.0.33(0)-release... Welcome 0 times Welcome 2 times Welcome 4 times Welcome 6 times Welcome 8 times Welcome 10 times
The seq command (outdated)
The seq command can be used as follows. A representative example in seq is as follows:
#!/bin/bash for i in $(seq 1 2 20) do echo "Welcome $i times" done
There is no good reason to use an external command such as seq to count and increment numbers in the for loop, hence it is recommend that you avoid using seq. The builtin command are fast.
Three-expression bash for loops syntax
This type of for loop share a common heritage with the C programming language. It is characterized by a three-parameter loop control expression; consisting of an initializer (EXP1), a loop-test or condition (EXP2), and a counting expression (EXP3).
for (( EXP1; EXP2; EXP3 )) do command1 command2 command3 done
A representative three-expression example in bash as follows:
#!/bin/bash for (( c=1; c<=5; c++ )) do echo "Welcome $c times..." done
Sample output:
Welcome 1 times Welcome 2 times Welcome 3 times Welcome 4 times Welcome 5 times
How do I use for as infinite loops?
Infinite for loop can be created with empty expressions, such as:
#!/bin/bash for (( ; ; )) do echo "infinite loops [ hit CTRL+C to stop]" done
Conditional exit with break
You can do early exit with break statement inside the for loop. You can exit from within a FOR, WHILE or UNTIL loop using break. General break statement inside the for loop:
for I in 1 2 3 4 5 do statements1 #Executed for all values of ''I'', up to a disaster-condition if any. statements2 if (disaster-condition) then break #Abandon the loop. fi statements3 #While good and, no disaster-condition. done
Following shell script will go though all files stored in /etc directory. The for loop will be abandon when /etc/resolv.conf file found.
#!/bin/bash
for file in /etc/*
do
if [ "${file}" == "/etc/resolv.conf" ]
then
countNameservers=$(grep -c nameserver /etc/resolv.conf)
echo "Total ${countNameservers} nameservers defined in ${file}"
break
fi
done
Early continuation with continue statement
To resume the next iteration of the enclosing FOR, WHILE or UNTIL loop use continue statement.
for I in 1 2 3 4 5 do statements1 #Executed for all values of ''I'', up to a disaster-condition if any. statements2 if (condition) then continue #Go to next iteration of I in the loop and skip statements3 fi statements3 done
This script make backup of all file names specified on command line. If .bak file exists, it will skip the cp command.
#!/bin/bash
FILES="$@"
for f in $FILES
do
# if .bak backup file exists, read next file
if [ -f ${f}.bak ]
then
echo "Skiping $f file..."
continue # read next file and skip cp command
fi
# we are hear means no backup file exists, just use cp command to copy file
/bin/cp $f $f.bak
done

- man bash
- help for
- help {
- help break
- help continue

Now with Invasion Iowa I’m even more in awe of how much I hate bad actors.
