*October 20, 2021*

*CRISPR,* presented by Dick Wagner.

The acronym “CRISPR” (Clustered Regularly Interspaced Short Palindromic
Repeats) has often been invoked when considering recent revolutionary
genetic engineering advances. This presentation will be devoted to the
origin of the term, its biological significance, and how further knowledge
led to the expansion of the meaning of this term as well as its underlying
processes in genetic engineering. Finally, the potential of CRISPR for
deriving further molecular biological information and uses from
experimentation and analysis will be discussed.



*SPECIAL NOTE - **Links to many of our previous sessions are available
online at http://lctg.toku.us/ <http://lctg.toku.us/>, thanks to the
diligence of Steve Isenberg. This includes the space-oriented presentations
of Mars Landing from February 24, Venus Temperature from March 17, Apollo
Mission from April 14, Space Debris from May 5, Oumuamua from May 19 and
Helicopter Flight on Mars from May 26.*



We, the Lexington Computer and Technology Group, will meet Wednesday at the
usual 10AM Eastern Time, BUT ONLINE, using the Zoom Video Conferencing
Application, facilitated by Steve Isenberg.

There is an instruction page at https://toku.us/zoomish but note that the
URL and phone number shown are examples.



Sometime after 9:45 AM on Wednesday, choose one of the following options:

   - If you have the Zoom application installed, start it and join meeting
   with ID 972 6146 0830
   - From your browser, go to: https://zoom.us/j/97261460830
   - From your smartphone, tap this: +16468769923,,97261460830
   - From a “dumb” telephone, call 1 646 876 9923 and enter meeting ID: 972
   6146 0830

Once the connection is established, you may need to locate and use the
on-screen controls that turn on the sound and the video. You should be able
to see and hear others and they should be able to see and hear you, if you
have a camera and microphone (each of which you can unmute selectively).

If this email wasn't addressed to you and you would like to join the group,
or if you have a friend or colleague who might also be interested in
joining, it's easy.  Ask them to go to the group's wiki page at
http://LCTG.toku.us and follow the simple instructions under "Join the
Email List".  By being a member of the group you'll get reminders of
upcoming meetings and infrequent related messages. No advertising.  The
list is tightly managed.

Membership is free and given that all meetings are using Zoom you only need
to be connected to the Internet to join.  It's ok to join from anywhere you
can get a decent Internet connection, even if you're in orbit around Earth
or on another planet or a moon (if you're connecting from somewhere not on
Earth, we'd like to chat).

*Below are our plans for Upcoming Meetings. For more schedule information,
please refer to https://wiki.toku.us/doku.php?id=lctg_speaker_schedule
<https://wiki.toku.us/doku.php?id=lctg_speaker_schedule>  We will continue
to have an online presentation (almost) every Wednesday until it is prudent
for us to resume meeting in person.*

*Decoding da Vinci.* This NOVA program will explain the science behind
Leonardo da Vinci’s masterpieces—and Mona Lisa’s iconic smile.

*November 3, 2021*

*Fritz Haber and Chemical Warfare,* Presented by Bretislav Friederich of
the University of Berlin where he is Professor of Physical Chemistry. He is
also a highly accomplished historian of science. He has just published a
chapter in a book on the history of chemical warfare, germ warfare and
other such technologies. His article is on Fritz Haber and his role in
inventing chemical warfare during WW1. Friederich will be at Harvard for
the year on sabbatical. He is an excellent speaker.
