Science 2 – Zoom Meeting, Friday 19th June 2020

It was pleasing that 21 members took part in our second Zoom meeting. Each time we use it we are getting a little more skilled in making this virtual meeting system work more effectively for us (mainly thanks to Mark Jackson, our IT consultant).

This time we had three mini presentations which utilised the screen sharing facility. John and Sue Tedstone talked about Ticknall Limeyards, which are within the grounds of Calke Abbey. These are a ‘Site of Special Scientific Interest (SSSI)’ and well worth a visit – when we can.

Ian Murray presented some interesting facts about Maria Telkes who was a Hungarian-American biophysicist, scientist and inventor who worked on solar energy technologies. She is considered one of the founders of solar thermal storage systems, earning her the nickname “the Sun Queen”.

Ann then discussed Florence Rena Sabin (1871-1953) who was an American anatomist and medical researcher. Her excellent and innovative work on the origins of the lymphatic system, blood cells, and immune system cells and on the pathology of tuberculosis was well-recognized during her lifetime.

This was followed by a general discussion about garden birds. Thanks to all participants.

The next meeting via Zoom is at 10.00 am on Friday, 17th July, 2020

Science 2 – Initial Zoom meeting

Science 2 – 22 May 2020 – Initial Zoom Meeting

Since it seems that face to face Interest Group meetings won’t happen for the next 2/3 months, today Science Group 2 held our first virtual Zoom meeting which ran relatively smoothly. However it highlighted some ways in which we can improve the next time we meet in June.

We started with a quick look at some information and questions sent in advance about hot food and using microwaves for cooking and other uses such as telecommunications, TV, satellites, radar and of course fixed traffic speed cameras.

Alan Ratcliffe then presented some interesting background to the life and work of scientist Rosalind Franklin.

Rosalind Franklin
Rosalind Elsie Franklin (25 July 1920 – 16 April 1958) was an English chemist and X-ray crystallographer whose work was central to the understanding of the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, coal, and graphite.
Although her works on coal and viruses were appreciated in her lifetime, her contributions to the discovery of the structure of DNA were largely recognised posthumously.

Thanks to all attendees. The next Zoom Meeting will be held on Friday June 19th from 9.45am to approx 10.30am. Ann Murray will do a presentation on the life in science of Florence Rena Sabinand, and Ian Murray on Maria Telkes. Plus members ‘just a minute’ on a science topic starting with their chosen letter of the alphabet.

Science Group 2

International Women’s Day was in March and Science 2 members were asked to research the work of some well known and some lesser known women scientists. Below is a small taster. Can you find out more information about any of them?

Dorothy Crowfoot Hodgkin 1910 – 1994
She is best known for her work in developing x-ray crystallography of biochemical compounds and was awarded the Nobel Prize for Chemistry in 1964 for determining the complicated structure of vitamin B12. Dorothy was considered to be a woman of great intellect with an immense passion for science. As a science, crystallography has produced 28 Nobel Prizes, more than any other scientific field.
(Mark Jackson)

May-Britt Moser (born 4 January 1963)
May is a Norwegian psychologist and neuroscientist, who is a Professor of Psychology and Neuroscience at the Norwegian University of Science and Technology (NTNU). She and her then-husband, Edvard Moser, shared half of the 2014 Nobel Prize in Physiology or Medicine, awarded for work concerning the grid cells in the entorhinal cortex, as well as several additional space-representing cell types in the same circuit that make up the positioning system in the brain. Together with Edvard Moser she established the Moser research environment at NTNU, which they lead. Since 2012 she heads the Centre for Neural Computation.
(Sue Knight)

Sylvia Alice Earle (née Reade; born August 30, 1935) is an American marine biologist, explorer, aquanaut, author, and lecturer who has led over 100 expeditions logging more than 7000 hours underwater and received many international honours for her work. Sylvia has been a National Geographic explorer-in-residence since 1998 and was the first female chief scientist of the U.S. National Oceanic and Atmospheric Administration. Named by Time Magazine as its first Hero for the Planet in 1998 and is also part of the group Ocean Elders, which is dedicated to protecting the ocean and its wildlife.

Science Group 2

As a Valentine’s Day treat(!) we had a group visit to the Horological Museum in Upton on the 14th February.

We had an interesting talk followed by a guided tour and were able to view and learn something about how the measurement of time has evolved.

Next Meeting: 20th March 2020: is ‘Women in Science Month’

Please complete and bring along your ‘homework’ for your mini presentations

There will also be a presentation by me about some lesser known women scientists.

April 17th

A catch up on Drug Trials, the protocols for testing and approving new drugs, ethical issues and an example of a trial that failed to identify the effect the drug would have on some patients.

Science 1 and 2 Joint Meeting – 28th May 2020

Science 1 and 2: a joint meeting: May 28th 10am to 12 noon

Both groups have been trying to access speakers to talk about aspects of Forensic Science.

On May 28th we have a presentation to both groups, an introduction to a basis for some forensic techniques called:

“Biometrics – There will never be another you …”
