COVID-19 vaccine developed

A messenger RNA Cozvid-19 vaccine, with 95% efficacy, is developed astonishingly fast; and production of 8 billion shots is achieved.

However, world wide distribution and acceptance of a vacination is less successful. Success hampered by:

• Public expectations of a vaccine, similar to measles, that provides a life time protection.
• Belief herd immunity could be achieved with wide vaccination.
• Spread of vaccine hesitancy, half-truths, misinformation, and a flood of lies along with the promotion of questionable unproven drugs and remedies.
• Evolution of different variants of the virus.
• Belief a specific mRNA vaccine could end the pandemic. And
• Wanting it to be over.

The future for ending the pandemic may be a long term struggle that will only be resolved with a pancoronavirus vaccine that will thwart any Sars-CoV-2.

Massachusetts v. Environmental Protection Agency, 549 U.S. 497, in a 5-4 decision found:

1. The petitioners were found to have standing. A state has a right to act in the interest of its citizens as to whether "its mountains shall be stripped of their forests and its inhabitants shall breathe pure air."
2. The Court held the CAA gives the EPA the authority to regulate tailpipe emissions of greenhouse gases. The CAA defines "air pollutant" as "any air pollution agent or combination of such agents, including any physical, chemical, biological, radioactive ... substance or matter which is emitted into or otherwise enters the ambient air".
3. The Court found the EPA's current rationale for not regulating to be inadequate and required the agency to articulate a reasonable basis in order to avoid regulation.

Chief Justice Roberts dissent argued the alleged injury: Massachusetts' loss of land because of rising sea levels is too speculative and without adequate scientific support and the effect of obliging the EPA to enforce automobile emissions as a solution is hypothetical at best.

Scalia's dissent found the Court has no jurisdiction to decide the case because the petitioners lack standing.

Tragedy of the Commons

Garrett Hardin writes his Tragedy of the Commons to describe problems for common resources. He explains how herders, who seek to maximize production, can increase herd size and over graze a common range. When production exceeds the range's capacity, then livestock suffer, production falls, and the ultimate tragedy: no rancher being able to graze the field, due to overconsumption. However, persuasive forces, such as: from a collective cooperative agreement or monarch, who apply coercion or social pressure for conservation of land, could achieve a sustainable environmental with appropriate management.

The idea of tragedy of the commons can be expanded to other land uses to provide food, shelter, aesthetic value, watershed for quality water to sustain agriculture and human health; conservation of wild life; healthy oceans; a clean atmosphere with balanced amounts of oxygen, nitrogen, and carbon dioxide, life sustaining climate; transportation; and intellectual knowledge rights.

DNA first identified

James Watson and Francis Crick demonstrate a model for deoxyribonucleic acid (DNA) as a double helix twisted ladder. It is essential to understand how genes control the chemical processes in living organisms.

They are assisted when Maurice Wilkins shows James a X-ray crystallography image of DNA made by Rosalind Franklin. Watson recognizes a double helix and he and Francis Crick publish it, and win a Nobel Prize for it in 1962.

Dorothy Crowfoot Hodgkin spends years perfecting the X-ray crystallography technique, for which she wins a Nobel Prize in 1964. She also determines the structures of penicillin, vitamin B12 and insulin.

Maria Tharp discoveres the Mid-Atlantic Ridge from mapping data.

When Maria transfers data from a 5000 foot scroll onto sheets of white linen to map the bottom of the Atlantic Ocean, a long rift valley appears.

Such a ridge is suggested by Wegner's theory of continental drift & plate tectonics.

However, most people believe continents are permanently attached to the surface of the Earth or they are too massive to drift so she is told by her superior to redo her work. After she does, the results are compared to another map by Bruce Heezen, and both maps describe rift valleys in the mid-ocean ridge. The results are published in 1957.

The article is read by the ocean explorer, Jacques Cousteau. He doubts Tharp's conclusions. Determined to prove her wrong he tacks her map to the dining room wall of his ship. However, when he views film he takes of the Atlantic Ocean floor, he sees a deep valley ridge where Tharp had mapped it.

Great London Fog or Big Smog

A five day air-pollution event in the United Kingdom; caused by cold weather and a lack of wind to move massive amounts of smoke created by the burning of coal and other fossil fuels for home use, transportation, and industry; is believed to have killed 12,000 and sickened 25,000. It leads to the Clean Air Act in 1956. Source

First amino acid sequence of a protein

Frederick Sanger finds a protein is a genetically created sequence of amino acids. He uses this ideas to determine the complete amino acid sequence of two polypeptide [protein] chains - bovine insulin A (1951) and bovine insulin B (1952). Next he determines how amide groups are distributed, and the location of the disulphide linkages which complete his deduction of the structure of insulin, in 1954. Source

Henrietta Lacks dies of cervical cancer on October 4, 1951, at age 31

Her cells are taken from her body and used to create the HeLa cell line. These cells are found to grow quickly, are very hardy, and survive longer than usual human cells. They became widely used in thousands of medical research experiments (cancer, polio vaccine, HIV, effects of toxins and radiation on cells, gene mapping, testing sensativity of cosmetics and other substance on cells, invitro fertilization, ... ). Since the cells were taken without her or her families permission their use and ownership eventually began discussions on ethical and legal use of peoples cells and genetic material. Source

Jack St. Clair Kilby invents an integrated circuit

Turned down by MIT to study electronics. He later says: it was because he didn't know it wasn't supposed to work that he tried it and found that it did. Serendipity?

First protein structures (myoglobin & hemoglobin) are determined with X-ray crystallography. Later Christian B. Anfinsen Jr. suggests that since a protein is thermodynamical stable it will make it possible to predict the structure of a protein based on the the sequence of its amino acids. Which will be solved in 2021

Barbara McClintock publishes, The origin and behavior of mutable loci in maize

By observing the patterns of coloration of maize kernels over generations of plants, Barbara determines that genes can move within and between chromosomes. Her findings aren't accepted and mostly ignored so she turns her study to the origins of maize in South America.

In the 1970's and early 1980's improvement in molecular science confirms her theory and these jumping genes are found in other microorganisms, insects and even humans. McClintock is awarded a Nobel Prize in 1983.

George Polya studies and identifies a heuristic to systematically solve problems

His classical book: How to Solve It, has been been found by students and educators as an authority for solving problems. In it he suggests four steps for solving mathematical problems:

1. Understand the problem
2. Make a plan
3. Carry out the plan
4. Look back on your work and ask, How could it be better?

Frozen food developer Clarence Birdseye learns from the Inuit that trout caught through holes in the ice can be frozen instantly in the air (which is 30 degrees below zero) tastes like fresh trout when it is cooked later. Unlike when food is frozen in the more usual slower way.

This leads him to develop a flash freezing method to create better tasting frozen meals and vegetables, which changes the way the world eats and provides people with quality food when it isn't in season. Source and more.

Penicillin

Howard Florey and Ernst Boris Chain isolated, purified, and create an injectable form of penicillin to use as an antibiotic.

Bacteria resistant antibiotics

A study shows bacteria could develop a resistance to penicillin even before penicillin is used to treat infections. However, the idea of killing bad bacteria and an increase in the discovery of antibiotics would accelerate the use of antibiotics in ways to contribute to resistant microbes rather than considering a more targeted and efficient use of antibiotics to reduce the evolution of drug resistant organisms.

DDT is found to kill insects and it begins to be used extensively as an insecticide. Sprays attached to mowers to spray yards before picnics, shelf paper with DDT embedded, paint, varnish, there were no limits on its use. Thought it would raise the standard of living, rid the world of malaria, fire ants and other pests that caused disease and harmed crops.

City planning for green space and community ...

Greenbelt, Maryland, is constructed from 1936 to 1938 by thousands of laborers, through the New Deal programs.

Clarence S. Stein is a consultant and creates design guidelines. Later Stein works to preserve the town as an example of a socially and environmentally responsible community design that can be used as a prototype for future desgins. Designs that combine superblocks of houses and apartments with pedestrian walkways through communal green space which join to a central area with commercial and recreational structures separate from roads for automobile travel.

In addition, the federal government promotes cooperative enterprises and associations in Greenbelt as a way to foster affordable housing and an enduring sense of community. While the cooperative nature of the towns are deemed a failure, the physical layout of the town is replicated by private developers. Source

Sulfa drug and antibiotics

Sulfa, also called sulfonamide, a synthetic antibiotic with a sulfanilamide molecular structure is the first chemical substance systematically created to treat and prevent bacterial infections in humans.

These effects are first observed in 1932, by Gerhard Domagk who notices that red dye Prontosil kills Streptococcus infections in mice.

Later researchers find the active agent is sulfanilamide, or para-aminobenzenesulfonamide, a metabolic product of Prontosil.

Dirac and the electron wave equation and the positron

Dirac presents to the Royal Society of London a relativistic wave equation for the electron. His equation requires four wave functions and introduces spins. It includes an extra set of solutions with negative values of energy.

In 1931 Dirac suggests this implies the existence of the antielectron, or positron. Later discovered in cosmic rays by Carl Anderson.

Holland Tunnel opens

It is the first vehicle tunnel, under the Hudson River, between Lower Manhattan in New York City and Jersey City, New Jersey.

Plans to bridge the Hudson River are first suggested in 1906.

However, in 1919 it is decided to build a tunnel under the river. Construction starts in 1920 to build, what is at the time, the longest continuous underwater vehicular tunnel in the world.

Clifford Milburn Holland is the chief engineer until his death in 1924. The problem of supplying breathable air to motorists in a closed system with running gasoline engines is solved by Ole Singstad, who designs the first mechanical ventilation system and supervises the tunnel's completion.
