The first flight on Mars will happen in April 2021 with the Ingenuity helicopter flying about one storey high for 60 seconds. It is part of the Perseverance mission rover that has already landed on the planet Mars. This video in WSJ shows how the Ingenuity helicopter was developed by NASA using a contractor Aeroenvironment which specializes in unmanned flight vehicles. The development process took 7 years and testing was done at the JPL Labs. JPL Labs has a vacuum space that can be filled with CO2 similar to atmosphere on MARS. 

Engineers doing the work for the helicopter say flight on MARS is challenging because of the thinner air. This will be a first in planetary flight compared to Wright Brothers first 120 second flight.

California is now the first state in the US to make vaccination mandatory for teachers. Teachers who turn down vaccination will need to undergo regular testing. This goes into effect Oct 15, 2021. California is also considering mandating eligible students to be vaccinated to attend school. Different states in the US are setting different rules for mask mandates for schools. California and Illinois require them, while 4 states have banned mask mandates in schools. 

The mandates and other action have pushed the fully vaccinated rate in California up to 64% for residents over 12 years, compared to 59% nationwide in US according to health data cited in the WSJ. Teachers unions in California support the rules. The largest union California Teachers Association, with 310,0000 educators, says 90% of its membership is vaccinated.

Heidi Vogt provides this exceptional account on the U.S. and international efort to build Liberia's healthcare system from scratch. Years of civil war till 2003 and the shortage of funds mean that even basic equipment such as X ray machines and blood testing equipment are lacking in Liberian hospitals. Even with a effort that includes the U.S. Army and Air Force planes, a 25 bed hospital for healthcare workers using tents will take till early November to be operational. Showing that the response is sorely inadequate here in Liberia leading to the spread of Ebola to Europe and the U.S. by December at the current pace. Liberia's head of Ebola control says the international community has failed Liberia with its inadequate response. For the U.S. and Europe an inadequate response creates new dangers as the public has lost confidence in government response.

What is the difference between South Korea and the U.S., Europe in the handling of coronavirus? It is tracking and testing.  President Trump and health adviser Dr. Fauci, see South Korea as the successful model to be followed in controlling the coronavirus. What has happened till now it is accepted with shortage of basic medical supplies and equipment, stress on hospital systems, are merely mitigation actions. South Korea was prepared for the coronavirus crisis because of the MERS and other epidemics, and failures resulting in corrective actions. Labs were centralized and better equipped for testing and tracking the infected. One of the key tools is testing. President Trump says the goal is for the U.S. to exceed and far surpass tests per capita in South Korea. Five million tests are planned by the end of April in the U.S. Where the U.S. falls short is in use of multipronged digital tracking using data from people's use of mobile phones, credit card usage, and use of apps designed to separate infected people from others. South Korea is a democracy with a population of 52 million people, about the size of France. People who were student activists in the democratization era in South Korea say the use of digital technology is a need today. We have to adapt in emergency situation they say. Ki Mo-ran, epidemiologist, and adviser to South Korean government says this is a key part lacking in the European and U.S. efforts to control coronavirus. She says in South Korea we know the patient's contacts, where he goes and stays, so we don't have to lock down everybody. Without digital tracking one cannot know which place is contaminated, which place is clean, so that there can be a lockdown of just that area and not the whole country, says Ki Mo-ran. She asks the question- is one person's privacy more important than the lives of a family or other people who are affected. Is it OK to lockdown every child in the country in a home as in Spain for over a month so that particular people's privacy is respected? These are serious questions for western society, are they exceptions or is democracy not just a western idea but equally cherished in Asian societies, people talk about Confucianism in China and the Asian culture forgetting that the biggest democracies are quite large and functioning well in India in addition to South Korea, Taiwan Indonesia, Malaysia, Bangladesh and Japan, far larger in area and population than China. The French government has chosen the app TraceTogether as the least intrusive one adaptable to France for use there. The U.S. is having Google and Apple develop one of its own. India will be developing one of its own. The NYT raises the question will it be watered down so much in France or in the U.S. and UK to be less effective than the  dire need for an alternative to lockdowns? ...

The U.S. is moving quickly to gain access to an effective vaccine by September or October 2020. It is doing this by providing the money for companies to conduct trials and ramp up manufacturing in a big way. The U.S. government has agreed to give Astra Zeneca upto $1.2 billion to secure supply of a Oxford University developed vaccine which could be ready by October. Astra Zeneca has agreed to make the vaccine under a licensing deal with Oxford University's Jenner Institute and promised it will not make a profit on this. U.S. has also given $483 million to Moderna in Cambridge, Massachusetts, for making the vaccine. Both Oxford and Moderna are testing the vaccine on humans. Oxford uses a tested older technology, Moderna a new technology. UK has given Astra Zeneca $79 million to secure 100 million doses of the vaccine, with 30 million ready by September. Oxford is also in negotiations with Gavi the international vaccine alliance, and Coalition for Epidemic Preparedness Innovations on further deals to boost production. Oxford began a 1100 person study in April, and is  doing a 5000 person trial in late May.  ...

Contact tracing being setup using iphones and android phones with bluetooth technology by Apple and Google. The idea is being studied for adoption by the U.S. government. The problem is that this kind of contact tracing is not as effective as the kind used by South Korea, Taiwan and Singapore with information from cellphone carriers. Contact tracing apps would be written by developers for each country and chosen by Apple and Google one for each country. How it works- When a person comes down with symptoms he can upload the information about who he has been close to stored on the phone. This information would then be used to contact the person who was exposed to the person with symptoms but unaware of this. A message would tell that person he was exposed to someone who now has symptoms and to contact public health authorites and take effective steps. When the person with symptoms gets tested if he was positive that would also appear on a exposed person's phone without name or other information.  The normal contact tracing is time intensive requiring many phone calls and using data from cellphone carriers. This is done in Singapore, Taiwan and South Korea. It is considered to be more effective. The approach of these Asian countries is more thorough and allows effective tracing and isolation, quarantining of persons having coronavirus or having exposure in countries with rampant coronavirus. The U.S. needs to move quickly to adopt the methods used in these Asian countries. The loss of hundreds of thousands of lives should be weighed against privacy concerns and clearly there should be a way to allow one time use of personal information for coronavirus, so that this kind of information is used only in public emergency situations. All three Asian countries are democracies. Putting health care workers at great risk including working pregnant doctors, as in the story in WSJ about a hospital in Maryland, should make it clear that everything including privacy concern should be placed in context, and use of personal information be permitted in a public emergency such as a contagious virus- with information protections removal for the period of the crisis. ...

CLT Classical Learning Test has a bright future. Its message is summed up in CLT Test 8 on the website- where Gustav Mahler is cited with the text- "Tradition is not about the worship of ashes, but the preservation of fire." 183,000 high school seniors have taken the CLT Classic Learning Test in the US in 2025 compared to 2 million for SAT and 1.4 million for ACT, yet the new test is considered to be more rigorous and includes the western intellectual tradition in ways that the ACT and SAT do not. A CLT Test 3 we looked at on the CLT site included for reading a poem by Amy Lovell 1916, Mark Twain writings, passages on Greek Zeno and Renaissance painter Raphael, EB White and others. CLT Test 4 has poetry of Robert Louis Stevenson 1885, and remarkably it has a passage on the Pack Horse Book Project of FDR's New Deal Initiative in 1935 on women librarians on horseback or with mules going into remote mountainous areas of the US including Kentucky, to teach rural people to read and write. This alone suggests it should appeal to Republican and Democratic states alike. It could include Charles Dickens and Shakespeare or Robert Frost's poetry. In that sense it is far more rigorous than short bland passages in SAT or ACT of little significance or educational value. It is designed to give students an exposure in classrooms to the western intellectual tradition that the elites in America have themselves grown up learning but who now have a haughty attitude to their own intellectual traditions. In CLT Test 6 we found a poem on Nature by Gerard Manley Hopkins 1877 and Dickens famous iconic passage that begins the Tale of Two Cities written about the French Revolutionary period which is clearly not what we find in SAT or ACT, and far better in conveying a feel of what America is about and where it came from. The founder of CLT Mr. Tate believes it will be the test most taken by high school seniors by 2040. Classic Learning Test now competes with SAT and ACT in North Carolina, Indiana and other American states. Arkansas passed legislation favoring CLT, and Ohio is doing it this year. Louisiana, Oklahoma and Wyoming are accepting CLT. This Test is gaining popularity among conservatives in red and purple states  and is getting the support of the US government in 2026. The Maryland Company behind this test is Maryland Learning Initiatives. Indiana passed legislation in March requiring its state universities to accept CLT scores. And North Carolina university system now accepts the CLT. Both CLT and SAT, ACT have Math and Reading Verbal tests, the CLT adds foundational texts from Western science, government, history and literature in ways not found in SAT, ACT. Students can take the CLT at home or at a testing site. More than 350 universities and colleges accept CLT says this report in Washington Post. The SAT and ACT use shorter passages and the reading material is bland and does not have the value that it could have from the western intellectual tradition. The passages in the CLT are more rigorous and include western religious tradition and thinkers but also poets, writers, scientists from the whole gamut of the experience of Europe and the United States of America. And also explore other countries and continents including China and India, from Aristotle to Gandhiji. ...

It is true carrots are good for eyesight and to prevent macular degeneration. Sunglasses help prevent ultraviolet rays from affecting the eyes. Reading without taking your eyes off the page is not conducive to good eye health- take time out every 20 minutes to look outside for at least 20 seconds. It is a good idea to relax the eyes by looking at Nature, what is good for mental health is also good for the eyes. Move the eyes to the left the right and draw large imaginary visualization circles with the eyes, large squares, for 30 seconds as away to exercize the eyes. Closing the eyes and concentrating on an imaginary visualization candle is a form of meditation that is also good for resting the eyes.

The NYT provides a good look at the situation in India in September where cases are over 4.5 million, the world's second largest after U.S. During the lockdown in April and May India had successfully stemmed the coronavirus. After reopening in June a lot has changed as can be seen in this look at the steep curve in June, July, August and September. Cases are now at the rate of 95,000 daily and deaths at 1172 daily as of September 9. The deaths are up 16% and cases up 29% over 2 weeks. Maps show the situation in the states with Maharashtra, Andhra, Tamilnadu, Karnataka, and Uttar Pradesh showing the highest cases. Maharashtra has about 1 million cases and the two states in the south east Andhra and Tamilnadu have about 1 million combined with Uttar Pradesh at about 250,000 cases. Delhi has about 200,000 cases. So that about half of the 4.5 million cases are in three states in the southeast and the western state where Mumbai (Bombay) is located. The increase was seen after increased testing from 200,000 a day to 1 million a day by the end of August, a steep jump being seen in late August and September. At the end of July the coronavirus recovery rate of 70% in India and 90% in Delhi were the favorable signs, until things changed in August with increased testing and the spread to rural areas. India is doing over 1 million tests daily. On September 3, 1.1 million people were tested, taking the total to 45 million tested throughout India.  As in Europe and America the reopening which is essential for the economy and jobs has resulted in a big jump in cases. The laws for lockdown were carefully obeyed without many of the problems seen in America and Europe, the early complete lockdown was implemented with success, and Indian pharmaceutical companies are some of the largest in the world giving the public wide access to essential medicines and drugs. The postal service has functioned remarkably well during the lockdown for delivery of essentials throughout the country, and earlier action to establish bank accounts for each and every individual in the country, has enabled rural Indians to get through this most difficult period. This has given the government some breathing room as it faces the cases from reopening in a vast country of 1380 million people.   ...

This WSJ report on critical analysis of coronavirus data has a very useful chart of Estimated Range of Symptomatic Cases Reported by Country. Complete coronavirus data for all symptomatic persons who have the coronavirus infection is lacking in most countries. Many people in large populations have symptoms and are positive but are not reflected in the official data collection. This is a big problem as the total number of cases are understated by a magnitude of twice to five times the numbers reported in official tally.   South Korea has done a good job of getting more of the symptomatic people with the infection in its data, as about 53% to 90% of such persons are reflected in official data. Next comes Germany at a range of 38% to 55%.  China comes third and has about 28% to about 38% of such persons reflected in its data, the U.S. currently on April 4 at about 14% to 19%, according to this chart in the WSJ. The source for this is Mathematical Modeling Center at the London School of Hygiene and Tropical Medicine. What this means is that the US. number of cases at 278,000  reported infected people with symptoms (April 4) is only 14% to 19% of the true number. Another way to say this is that the actual infected persons with symptoms is about 5 times what is reported, or over 1 million not the 278,000 reported.  As happens for China data collection agencies may never get the true number. To be comparable to the Chinese numbers, as the U.S. is a large country, the figure closer to the true numbers would be twice the 278,000 reported or over half a million symptomatic infections of coronavirus in the U.S. Why is this data important. With widespread testing as in South Korea one gets data that tells one how many people are infected (the size of the problem) and therefore the resources needed and the point of greatest impact. Also it tells one the typical transmission rate per person, and it helps hospitals in each area know what to expect and what resources are needed to prepare- not find people suddenly turn up in the E.R. in unpredictable numbers. The lack of widespread testing and better reporting in the data to get a grip on the pandemic is shown in this chart for countries hardest hit, less than 5-6% for Italy and Spain. The UK and France at 5-8%.   ...

Janet Yellen, Fed chairwoman, says the financial system is safer now after the financial regulation, stress testing, living wills and other changes that the Federal Reserve has implemented. She says there is no need for a reduction in these key regulatory rules. One of the changes is that banks now use a safer mix of financing- equity financing has doubled for capital, and wholesale borrowing is cut in half, since the 2008 financial crisis that took the U.S. and with it the global financial system to the brink of disaster. The appointment of Randall Quarles to the Fed by the Trump administration was intended to  reduce regulation, and this is Yellen's response to such proposed ideas.

The University of Washington Institute of Health Metrics and Evaluation has doubled its forecast of coronavirus deaths in the U.S. to 135,000, about twice what it is today at 69,000, by early August 2020. This is based on the assumption that with reopening the economy and return to actively operating in offices and shops, in construction and factories, the social distancing will be relaxed. Factors such as rising temperatures are not seen as offsetting the increased mobility in reopening. Dr. Fauci, top U.S. infectious disease official said on My 4, that the relaxing of social distancing could get a rebound started considering the coronavirus "phenomenal capabilities of spreading like wildfire." There is concern that the cases may be much higher in Brazil where there is not much testing, even higher than in the U.S. according to one university study. Argentina is a contrast having imposed a lockdown much earlier and has only 246 coronavirus deaths. ...

A growing consensus among experts that it is not so much surface contamination as the air we breathe in that is the problem. The longer you spend time with people talking in face to face interactions, or inhaling air aerosolized in the air from small droplets, the easier it is to get the virus. This means social distancing matters in a big way. Masks are a big way to cut the risk. The worst you can do then is to be in a crowded event, ot have closeup face to face interactions for long periods. Being where there is loud talking or singing is a bad idea. This is why actions such as plexiglass installed as barrier, requiring masks in stores, using good ventilations systems and keeping windows has an enormous impact. This means that people can do a lot of work, exercize and other activities outside if one takes the basic precautions to heart and practices seriously. Contact tracing and testing, and other measures can be targeted to keep the spots that have a surge under control. ...

Prof. David Spiegelhalter of Cambridge University is critical of the British government for not finding out how many people may be infected by coronavirus. He says he is not telling how anybody should feel or what they should be worried about, but at least the people's anxiety should be proportional to the risks they actually face. His estimate is that based on the death rate of 1% its possible that there could be 3.5 million people in Britain who are infected with coronavirus or higher. Sir Spiegelhalter is professor at Cambridge University for the public understanding of science. He says this "basic information" is essential in making the decision such as how far and when to go out of lockdown, and that the British government has failed to do this in a timely manner required for tackling coronavirus without risking more lives.

By preventing serious illness in patients two pills for coronavirus from Pfizer and Merck can change the course of this pandemic. Pfizer will give a royalty free license to Medicines Patent Pool, an organization backed by the United Nations for its coronavirus pill. Merck has also given a royalty free license to Medicines Patent Pool for it pill. This organization will then grant a license for the manufacture of the coronavirus pills to poor developing countries. India is included in the list of countries yet China, Russia and Brazil are excluded for the Pfizer license.  Merck has given Indian generics manufacturers approval to make the pill. This will provide supplies of the pill to 105 developing countries, South Africa will also make the pill to provide it at $10 a course in Africa. Pfizer will begin manufacturing of large quantities in 2022 with 50 million planned for 2022 and 21 million in the first half of 2022. Pfizer pill will be made available in 95 countries. The Merck pill is called Molnupiravir. Pfizer pill is called Paxlovid with 30 pills taken over the course of 5 days. Pfizer pill is effective in studies when given to people who had not been vaccinated. It has to be given within 3-4 days of getting coronavirus confirmed through a test which makes testing critical for its use. ...

The Oxford vaccine developed by British scientists could be ready by September. Astra Zeneca has joined with Oxford so that it can produce 100 million vaccine doses by the end of the year. This is because in a sense the vaccine is not new. It uses an existing tech platform where there is a lot of experience. The use of ring vaccination method shortens the process of testing on humans the vaccine to a few months. The core of the virus ChAdox1 already exists in chimpanzees and has a mild effect on humans. This is an adenovirus. It is combined with another virus to produce the covid vaccine for coronavirus. Researchers at Oxford have used ChAdox1 in the past to test vaccines for Ebola and MERS as well as other virus.  Already tests have been conducted on rhesus macaques. The rhesus macaques given the vaccine at a Montana lab did not get coronavirus.The surface protein of coronavirus is simply added to the ChAdox1 so that it is able to attach to host cells and infect them in the human body, and let antibodies develop from this. The purpose is to let the human body develop defense mechanism against this attaching to a human cell.   ...

These simulations show the  importance of flattening the curve for coronavirus especially the steep jump in the curve when it grows exponentially as people mingle in crowded environments, on trains and subways, and in public gatherings of more than 10 people. This is shown here in four different simulations in the Washington Post. Social distancing and quarantine worked in China, Taiwan, Singapore and South Korea. Though the attempted quarantine simulation here does not cover the situations in China, Taiwan and Singapore where quarantine has worked and was the only way to tackle the coronavirus in time to do least damage. Additional simulations would show the way it was limited in Singapore through contact tracing and mandated staying at home for all who have come in contact with affected persons. And in South Korea a simulation could show how this worked through containment by testing and limiting spread, or China by an effective quarantine or lockdown of a city or province.  The basic idea is to limit contact and separate so that intermingling is restricted to as few places as possible for a limited period during which health authorites can achieve a controlled situation through systemwide organized efforts.  ...

As this report in WSJ shows underreporting of coronavirus cases is a serious problem for Africa, and the figures from Africa's CDC, part of the African Union, do not show the magnitude of the problem. It shows that health workers in places from Yaounde in Cameroon to Dar es Salaam in Tanzania, to cities in Somalia, are reporting a situation quite different from what the CDC shows, with hotspots emerging in some places with little in the way of resources.

Only 1 million tests have been done and half are in SOuth Africa and Ghana. WIthout the testing it is hard to know how many cases there are. Capetown area in South Africa is emerging as a hotspot and hospitals are expected to be overwhelmed within weeks. Officially Tanzania a country with 56 million has 509 cases and 21 deaths, yet this contrasts with reports from health experts. Cameroon and South Sudan are also possible emerging hotspots in addition to Tanzania says this report in WSJ.
