The Parrondo’s paradox, has been described as: A combination of losing strategies becomes a winning strategy. […]

Consider two games Game A and Game B, this time with the following rules:

1. In Game A, you simply lose $1 every time you play.
2. In Game B, you count how much money you have left. If it is an even number, you win $3. Otherwise you lose $5.

Say you begin with $100 in your pocket. If you start playing Game A exclusively, you will obviously lose all your money in 100 rounds. Similarly, if you decide to play Game B exclusively, you will also lose all your money in 100 rounds.

However, consider playing the games alternatively, starting with Game B, followed by A, then by B, and so on (BABABA…). It should be easy to see that you will steadily earn a total of $2 for every two games.

Thus, even though each game is a losing proposition if played alone, because the results of Game B are affected by Game A, the sequence in which the games are played can affect how often Game B earns you money, and subsequently the result is different from the case where either game is played by itself.

We then showed that SARS-recovered patients still possess long-lasting memory T cells reactive to SARS-NP 17 years after the 2003 outbreak, which displayed robust cross-reactivity to SARS-CoV-2 NP. Surprisingly, we also frequently detected SARS-CoV-2 specific T cells in individuals with no history of SARS, COVID-19 or contact with SARS/COVID-19 patients.

Perhaps there’s just little selection pressure on the virus as it races through millions of immunologically naïve people, scientists say. That could change with the advent of vaccines or new therapies, forcing the virus to evolve. But it could also indicate that the virus has been with people longer than we know, and was spreading before the first known cases in Wuhan, China, in December 2019. “The evolution of this virus to become a human pathogen may have already happened and we missed it,” Rasmussen says.

Wang thinks a version of the virus may have circulated earlier in humans in southern Asia, perhaps flying under the radar because it didn’t cause severe disease.

Scientists Say You Can Cancel the Noise but Keep Your Window Open — Researchers in Singapore have developed an apparatus that can be placed in a window to reduce incoming sound by 10 decibels. […] The prototype is not yet the most practical device in real world conditions, but it points the way toward the development of technologies that may help ease the strain of noisy city living. Borrowing from the same technological principles used in noise-canceling headphones, the team expanded the concept to fit an entire room by placing 24 small speakers in a window. The speakers emit sound waves that correspond to the incoming racket and neutralize it — or, at least some of it. [NY Times]

What Miniature Lab-Grown Brains Reveal About the Effects of Covid-19 […] Known as “mini brains,” or organoids, these minuscule structures made from stem cells contain neurons that spontaneously emit electrical activity as a real brain would. […] What she found was that the virus could infect the mini brains and, 72 hours later, it began multiplying inside them, suggesting that human brain cells are susceptible to the virus. 

If SARS-CoV-2 is airborne—which basically means tiny viral particles can survive air for at least a few hours and still infect people—it’s far from the only disease. Measles is notorious for being able to last in the air for up to two hours. Tuberculosis, though a bacterium, can be airborne for six hours, and Lisa Brosseau, a retired professor of public health who still consults for businesses and organizations, suggests that coronavirus superspreaders (people who seem to eject a larger amount of the virus than others) disseminate the virus in patterns that recall the infectiousness of tuberculosis. The evidence that this type of transmission is happening with SARS-CoV-2  arguably already exists. Several big studies point to airborne transmission of the virus as a major route for the spread of covid-19. [Technology Review]

University of Oxford researchers found the proportion of coronavirus patients dying each day in England fell from 6% to 1.5% between April and June.

Spain’s large-scale study on the coronavirus indicates just 5% of its population has developed antibodies, strengthening evidence that a so-called herd immunity to Covid-19 is “unachievable” […] There have been similar studies in China and the United States and “the key finding from these representative cohorts is that most of the population appears to have remained unexposed” to Covid-19, “even in areas with widespread virus circulation” […] “Some experts have computed that around 60% of seroprevalence might mean herd immunity. But we are very far from achieving that number.” [CNN]

A big question is whether somebody who has had COVID-19 is now immune from getting it again. So far we don’t see compelling evidence of people getting reinfected, but that’s still a bit early to say for sure. That’s going to make a huge difference in everything we try to do about this going forward. A vaccine, of course, depends upon the idea that immunity is protective. […] There are a couple factors that will relate to whether immunity lasts a long time. One is whether the antibodies that somebody generates after infection are around for years afterward or whether they fade away. There hasn’t been enough time yet to be able to say that. The other is whether the virus itself changes its biology and then evades the immune response that people have had. Obviously that’s a big deal with influenza, which is why we have to get a flu shot every year. And it’s been a horrible deal with HIV — and why we’ve never been able to get a vaccine for it, because HIV is changing its coat almost hourly. I think we have reason to be much more optimistic about SARS-CoV-2 [the virus that causes COVID-19]. There doesn’t seem to be compelling evidence of it being that highly mutable. It’s a typical RNA virus that seems to have a typical mutation rate. It doesn’t look like it’s doing a lot of changing of its coat proteins. So I’m fairly reassured by what we’ve learned so far, after looking at the viral genome of thousands of isolates, that this one is not changing that rapidly. […] I am guardedly optimistic that by the end of 2020 we will have at least one vaccine that has been proven safe and effective in a large-scale trial. […] There are at least four vaccines that will be getting into such large trials this summer beginning as early as July. […] Maybe all four of them will work. […] there will be, then, a time of having to do the scale-up to have billions of doses, which might be what the world needs. So there will still be some time involved, even though we are doing everything possible to prepare for that by manufacturing millions of doses of each of those vaccines even before we know if they would work, so that the highest-risk people can get access right away.

…a girl with different-colored eyes and ambiguous genitals who appeared at a Seattle genetics clinic. Her ovaries proved to have only XX chromosomes—typical female—but her other tissues were mixtures of XX and XY. Further analysis showed that she had started out as opposite-sex twins. But early in development, the two embryos had fused, becoming a single, highly unusual child. Like a verse from the old Ray Stevens novelty song “I’m My Own Grandpa,” this girl was her own twin brother.

In pregnant women, fetal stem cells can cross the placenta to enter the mother’s bloodstream, where they may persist for years. If Mom gets pregnant again, the stem cells of her firstborn, still circulating in her blood, can cross the placenta in the other direction, commingling with those of the younger sibling. Heredity can thus flow “upstream,” from child to parent—and then over and down to future siblings.

Forget the notion that your genome is just the DNA in your chromosomes. We have another genome, small but vital, in our cells’ mitochondria—the tiny powerhouses that supply energy to the cell. Though the mitochondrial genes are few, damage to them can lead to disorders of the brain, muscles, internal organs, sensory systems, and more. At fertilization, an embryo receives both chromosomes and mitochondria from the egg, and only chromosomes from the sperm. Mitochondrial heredity thus flows strictly through the maternal line; every boy is an evolutionary dead end, as far as mitochondria are concerned.

To fully restart the U.S. economy by August, massive population testing for infections with the virus that causes COVID-19 is essential […] test 2 to 6% of the population per day, or between 5 and 20 million people per day […] The authors of the report estimate that this scheme for testing, tracing, and supported isolation (TTSI) would cost between $50 to $300 billion over two years. As they note this is extremely cheap compared to “the economic cost of continued collective quarantine of $100 to 350 billion a month.”

Why We Must Test Millions a Day

studies have suggested that many people who’ve never been infected with SARS-CoV-2, but who have semi-recently recovered from a common-cold coronavirus, may boast partial immunity to COVID-19. […] Chinese researchers monitored antibody levels in 74 COVID-19 patients — one half symptomatic, the other asymptomatic — for months after their recoveries. The scientists found that more than 90 percent of these patients displayed sharp drop-offs in antibody levels two-to-three months after their initial infections. […] The dominant strain of coronavirus in the U.S. may be more contagious than the initial variety. […] study found that the newer coronavirus strain has about five times more functional and intact spike proteins in each of its particles than its predecessor did. [NY mag]

Pool testing combines samples from several people and tests them for the coronavirus all at once, cutting down on the time and supplies required. […] “If everyone is negative, then you’re done” […] If the test detected the presence of the virus, then each person would have to be tested and the results individually analyzed to determine whose sample produced the positive result. […] How many samples are pooled? Researchers have generally suggested quantities between three and 50. The bigger the pool, the more likely a positive case with a low viral load will be too diluted to trigger detection of the virus. [Washington Post]

Norway, Denmark and Finland have closed their borders to Swedes, fearing that they would bring new coronavirus infections with them.

The white iPhone with chipped paint that Moroccan journalist Omar Radi used to stay in contact with his sources also allowed his government to spy on him. They could read every email, text and website visited; listen to every phone call and watch every video conference; download calendar entries, monitor GPS coordinates, and even turn on the camera and microphone to see and hear where the phone was at any moment. Yet Radi was trained in encryption and cyber security. He hadn’t clicked on any suspicious links and didn’t have any missed calls on WhatsApp — both well-documented ways a cell phone can be hacked. Instead, a report published Monday by Amnesty International shows Radi was targeted by a new and frighteningly stealthy technique. All he had to do was visit one website. Any website. Radi’s phone shows that it was infected by “network injection,” a fully automated method where an attacker intercepts a cellular signal when it makes a request to visit a website. In milliseconds, the web browser is diverted to a malicious site and spyware code is downloaded that allows remote access to everything on the phone. [The Star]

Researchers have discovered that, contrary to longstanding assumptions, the Y chromosome is not limited to a handful of masculine tasks, like specifying male body parts in a developing embryo or replenishing the sperm supply in an adult man. New evidence indicates that the Y chromosome participates in an array of essential, general-interest tasks in men, like stanching cancerous growth, keeping arteries clear and blocking the buildup of amyloid plaque in the brain. As a sizable percentage of men age, their blood and other body cells begin to spontaneously jettison copies of the Y chromosome, sometimes quickly, sometimes slowly. That unfortunate act of chromosomal decluttering appears to put the men at a heightened risk of Alzheimer’s disease, leukemia and other disorders. [NY Times]

It’s growing clearer that the coronavirus does not spread in an orderly way. Each infected person might infect two others on average but most people who get it infect no one.

On the diagram, where DeRisi’s cursor lingers, he highlights a person with a particular talent for spreading the disease. The genetic information shows you the urgency of getting that person into quarantine, but it does more than that: It has the potential to lead you more generally to the social activity that’s spreading the disease.

It works the other way, too. The approach DeRisi has developed can be used not just to shut things down but to open them up. Last week, in Northern California, a pair of workers at a fish-packing plant came down with symptoms of Covid-19. The Biohub processed their tests and found both workers had the virus. In an age not all that distant from ours, the fish-packing plant, which believed it had taken the measures to keep its workers safe, would have been forced to close, as it would have had to assume that one of the workers had infected the other on the job. But then Joe DeRisi’s Badass Virus Hunters sequenced the two viruses and showed they were genetically far apart: The two workers had contracted the virus independently and outside of work. The fish-packing plant was able to stay open — and its workers were able to stay on their jobs.

Potential weapons against covid-19 include manufactured antibodies, serum transfusions from survivors, antivirals, steroids, and more than 100 vaccine candidates, some now advancing toward decisive tests in volunteers. But there’s another approach to battling the virus—one that hasn’t won much attention, but which in the future could become the fastest way to beat back a pandemic. It involves isolating genetic material from survivors and injecting it directly into others, lending them protection against the pathogen. DNA-encoded antibodies, as these therapeutics are called, have shown promising results in animals. In humans, genes injected into the arm or leg would convert the recipient’s muscle cells into factories to make antibodies against the virus. That could provide temporary immunity or lessen the severity of the disease for those already infected. [Technology Review]

“We shouldn’t think that, once we get to a vaccine—whenever that is—and once we’re able to arrest this virus, that we’ll be able to rest easy. We are in a new era of more frequent, higher-impact, higher-velocity zoonotic threats.”

An infection that causes severe symptoms is likely to lead to a stronger immune response, which would also help encourage strong and longer-lasting immunity moving forward. On the flip side, a mild or asymptomatic case is likely to yield lower antibody levels, as was found in covid-19 patients in a new study published in Nature Medicine

More driving means more congested traffic. So to reduce congestion, it makes sense to build more highway lanes so that more cars can fit. A new report shows that doesn’t work at all. Between 1993 and 2017, the researchers found that the largest urban areas in the U.S. added 30,511 new lane-miles of roads—a 42 percent increase. That’s a faster rate of growth than population growth, which rose by 32 percent in those cities over the same time period. But in that 24 year period, traffic congestion didn’t drop at all. In fact, it rose by 144 percent.

As my colleague Paul Krugman cannot stress enough, the stock market is not the economy. In fact, as a wise person on TikTok once said, it’s more of a graph of rich people’s feelings. But that raises the question: Why are rich people feeling so optimistic, and what does that imply about the way the economy works? […] if the market seems to be recovering faster than the rest of the country, it’s at least in part because of “the government’s policy of giving out free money,” in the words of the investor Leon Cooperman. […] many companies are doing exceedingly well, particularly big technology corporations. Five of those — Microsoft, Apple, Amazon, Alphabet (Google’s parent company) and Facebook — together make up about 20 percent of the S.&P. 500, and they’ve all posted significant gains.

Results showed that bisexual individuals reported higher levels of openness than homosexual individuals, who in turn, reported higher levels of openness than heterosexual individuals. Bisexual individuals also report lower levels of conscientiousness than both heterosexual and homosexual individuals. Sex moderation effects showed that homosexual men scored higher than heterosexual men on neuroticism, agreeableness and conscientiousness, whereas homosexual women scored lower than heterosexual women on extraversion, agreeableness, and conscientiousness. There was also evidence that personality differences between sexual orientation categories tend to decline with age. [Taylor & Francis Online]

Fenn, 89, told the Santa Fe New Mexican that a treasure hunter located the chest a few days ago. […] Fenn posted clues to the treasures whereabouts online and in a 24-line poem that was published in his 2010 autobiography The Thrill of the Chase.

Some have said it was a hoax and pursued lawsuits. Many quit their jobs to dedicate themselves to the search and others depleted their life savings. At least four people are believed to have died searching for it. [The Guardian]

We hypothesize that pollen may explain the seasonality of flu-like epidemics including COVID-19. […] We conclude that pollen is a predictor for the inverse seasonality of flu-like epidemics including COVID-19, and solar radiation is a co-inhibitor. The observed seasonality of COVID-19 during Spring, suggests that COVID-19 may revive in The Netherlands after week 33 [mid-August].
