It is widely regarded as the world's most potent spyware, capable of reliably cracking the encrypted communications of iPhone and Android smartphones. The software, Pegasus, made by an Israeli company, NSO Group, has been able to track terrorists and drug cartels. It has also been used against human rights activists, journalists and dissidents. Now, an investigation published Friday by The New York Times Magazine has found that Israel, which controls the export of the spyware ... has made Pegasus a key component of its national security strategy, using it to advance its interests around the world. The F.B.I. bought and tested NSO software for years with plans to use it for domestic surveillance until the agency finally decided last year not to deploy the tools. The F.B.I., in a deal never previously reported, bought the spyware in 2019. It also spent two years discussing whether to deploy a newer product, called Phantom, inside the United States. The discussions at the Justice Department and the F.B.I. continued until last summer. But Pegasus equipment is still in a New Jersey building used by the F.B.I. And the company also gave the agency a demonstration of Phantom, which could hack American phone numbers. A brochure ... says that Phantom allows American law enforcement and spy agencies to "turn your target's smartphone into an intelligence gold mine." In 2018 ... the C.I.A. bought Pegasus to help Djibouti, an American ally, fight terrorism, despite longstanding concerns about human rights abuses there.

The drama surrounding Peng Shuai is following a familiar script, in which someone who has run afoul of China's Communist government disappears from view. What happens next depends on the case, but it is not uncommon for the person in question to disavow the statements or actions that first upset officials. Other times, the person simply keeps a lower profile. Sometimes, their arrest is eventually announced. Peng's saga began in November, when she wrote in a social media post that a former member of the party's all-powerful Politburo Standing Committee had forced her to have sex three years ago despite repeated refusals. The post was quickly taken down and the former top-ranked doubles player dropped out of public view late last year. After she reappeared weeks later, she denied to a Singapore newspaper that she ever made any accusation of sexual assault. In an interview published Monday by a French sports paper, the tennis player called the whole situation an "enormous misunderstanding." Other people ... have disappeared over the years – a phenomenon that has expanded since President Xi Jinping came to power in 2013. Liu [Xiaobo], a dissident writer who joined calls for increased freedoms in China in 2008, was detained a day before the appeal for reforms was released. After his arrest, his whereabouts were unknown for a time. He was eventually accused of subversion and sentenced to 11 years in prison. He was awarded the Nobel Peace Prize and died of cancer before he was ever released.
Note: What most likely happens is that these people are subjected to well established mind control procedures, such that afterward they dare not challenge those in power.

Four African countries have reported new cases of polio linked to the oral vaccine, as global health numbers show there are now more children being paralyzed by viruses originating in vaccines than in the wild. In a report late last week, the World Health Organization and partners noted nine new polio cases caused by the vaccine in Nigeria, Congo, Central African Republic and Angola. Seven countries elsewhere in Africa have similar outbreaks and cases have been reported in Asia. Of the two countries where polio remains endemic, Afghanistan and Pakistan, vaccine-linked cases have been identified in Pakistan. In rare cases, the live virus in oral polio vaccine can mutate into a form capable of sparking new outbreaks. All the current vaccine-derived polio cases have been sparked by a Type 2 virus contained in the vaccine. Type 2 wild virus was eliminated years ago. WHO and partners have long relied on oral polio vaccines because they are cheap and can be easily administered. Western countries use a more expensive injectable polio vaccine that contains an inactivated virus incapable of causing polio. The Independent Monitoring Board, a group set up by WHO to assess polio eradication, warned in a report this month that vaccine-derived polio virus is "spreading uncontrolled in West Africa." The group said officials were already "failing badly" to meet a recently approved polio goal of stopping all vaccine-derived outbreaks within 120 days of detection.

Congress on Thursday gave final approval to legislation guaranteeing that people who experience sexual harassment at work can seek recourse in the courts, a milestone for the #MeToo movement that prompted a national reckoning on the way sexual misconduct claims are handled. The measure, which is expected to be signed by President Joe Biden, bars employment contracts from forcing people to settle sexual assault or harassment cases through arbitration rather than in court, a process that often benefits employers and keeps misconduct allegations from becoming public. Significantly, the bill is retroactive, nullifying that language in contracts nationwide and opening the door for people who had been bound by it to take legal action. Sen. Kirsten Gillibrand, who has spearheaded the effort, called it "one of the most significant workplace reforms in American history." "No longer will survivors of sexual assault or harassment in the workplace come forward and be told that they are legally forbidden to sue their employer because somewhere in buried their employment contracts was this forced arbitration clause," she said. Gillibrand, who has focused on combating sexual harassment and sexual misconduct in the military, originally introduced the legislation in 2017. The legislation had uncommonly broad, bipartisan support. That allowed the bill to be passed in the Senate by unanimous consent – a procedure almost never used for significant legislation, especially one affecting tens of millions of Americans.

For the past decade, 15-year-old Finnish students have consistently been at or near the top of all the nations tested in reading, mathematics, and science. And just as consistently, the variance in quality among Finnish schools is the least of all nations tested, meaning that Finnish students can get a good education in virtually any school in the nation. That's equality of educational opportunity, a good public school in every neighborhood. What makes the Finnish school system so amazing is that Finnish students never take a standardized test until their last year of high school, when they take a matriculation examination for college admission. There is a national curriculum – broad guidelines to assure that all students have a full education – but it is not prescriptive. Teachers have extensive responsibility for designing curriculum and pedagogy in their school. Teachers are prepared for all eventualities, including students with disabilities, students with language difficulties, and students with other kinds of learning issues. The schools I visited reminded me of our best private progressive schools. They are rich in the arts, in play, and in activity. Finland has one other significant advantage over the United States. The child-poverty rate in Finland is under 4 percent. Here it is 22 percent and rising. It's a well-known fact that family income is the most reliable predictor of academic performance. Finland has a strong social welfare system; we don't. It is not a "Socialist" nation, by the way. It is egalitarian and capitalist.

Finland's school system has consistently come at the top for the international rankings for education systems. So how do they do it? It's simple – by going against the evaluation-driven, centralized model that much of the Western world uses. Finnish children don't start school until they are 7. Compared with other systems, they rarely take exams or do homework until they are well into their teens. The children are not measured at all for the first six years of their education. There is only one mandatory standardized test in Finland, taken when children are 16. All children, clever or not, are taught in the same classrooms. Finland spends around 30 percent less per student than the United States. 30 percent of children receive extra help during their first nine years of school. 66 percent of students go to college. The difference between weakest and strongest students is the smallest in the World. Science classes are capped at 16 students so that they may perform practical experiments every class. 93 percent of Finns graduate from high school. 17.5 percent higher than the US. Elementary school students get 75 minutes of recess a day in Finnish [schools] versus an average of 27 minutes in the US. Teachers only spend 4 hours a day in the classroom, and take 2 hours a week for "professional development". Teachers are effectively given the same status as doctors and lawyers. In an international standardized measurement in 2001, Finnish children came top or very close to the top for science, reading and mathematics.

NSO Group [is] the world's most notorious maker of spyware. The F.B.I. had bought a version of Pegasus, NSO's premier spying tool. It could ... crack the encrypted communications of any iPhone or Android smartphone. Since NSO had introduced Pegasus to the global market in 2011, it had helped Mexican authorities capture JoaquĂn Guzmán Loera, the drug lord known as El Chapo. European investigators have quietly used Pegasus to thwart terrorist plots, fight organized crime and, in one case, take down a global child-abuse ring. Mexico deployed the software not just against gangsters but also against journalists and political dissidents. The United Arab Emirates used the software to hack the phone of a civil rights activist. Saudi Arabia used it against women's rights activists. During a presentation to officials in Washington, the company demonstrated a new system, called Phantom, that could hack any number in the United States that the F.B.I. decided to target. A slick brochure ... says that Phantom allows American law enforcement and spy agencies to get intelligence "by extracting and monitoring crucial data from mobile devices." It is an "independent solution" that requires no cooperation from AT&T, Verizon, Apple or Google. The system, it says, will "turn your target's smartphone into an intelligence gold mine." The Phantom presentation triggered a discussion among government lawyers. Last summer ... the F.B.I. finally decided not to deploy the NSO weapons.

Depression among adults in the United States tripled in the early 2020 months of the global coronavirus pandemic–jumping from 8.5 percent before the pandemic to a staggering 27.8 percent. New research from Boston University School of Public Health reveals that the elevated rate of depression has persisted into 2021, and even worsened, climbing to 32.8 percent and affecting 1 in every 3 American adults. The study is the first nationally representative study in the US that examines the change in depression prevalence before and then during the pandemic. Published in the journal The Lancet Regional Health–Americas, the study found that the most significant predictors for if a person experienced depressive symptoms during the pandemic were low household income, not being married, and experiencing multiple pandemic-related stressors. "The sustained high prevalence of depression does not follow [the same] patterns [we observed] after previous traumatic events, such as Hurricane Ike," says study senior author Sandro Galea. "Typically, we would expect depression to peak following the traumatic event and then lower over time. Instead, we found that 12 months into the pandemic, levels of depression remained high." The burden of depression intensified over the course of the pandemic and disproportionately impacted adults with lower incomes. By spring 2021, low-income adults were 7 times more likely to experience [elevated depressive] symptoms.
Note: Note that this huge increase in depression was caused not directly by the pandemic, but more by the isolation of the lockdown measures instituted.

Since the start of the pandemic, childcare costs have gone through the roof. Across the U.S., parents are seeing an average annual cost increase of 41% for center-based childcare providers, and spending an average of $14,117 annually, up from $9,977 pre-pandemic, according to data from a recent LendingTree report. Households with children younger than 5 were hit hardest by these increases, the report found. Since the pandemic began, center-based care providers for 3- and 4-year-olds have seen their annual costs increase by 57%. Costs for center-based care providers for kids under 2 grew by 37%. Care providers for 3- and 4-year-olds in Georgia, Florida, and Louisiana saw the biggest jump in expenses, with an annual average increase of at least 144%. As for the direct impact on households, Indiana families with kids under 5 put the biggest chunk of their income–20%–toward childcare, with the average family spending $11,212 a year. Vermont families are close behind, with 19% of their paycheck–an average of $13,538 annually–going toward childcare. Families in New Jersey, Mississippi, Kentucky, Texas, and North Dakota pay the lowest portion, at 11%. But they may also be seeing a jump in their costs in the near future; in each of those states, the average care center saw its expenses increase by over 50% during the pandemic. The bulk of the increased costs stems from staffing, which the Center for American Progress says makes up 70% of a childcare provider's total budget.
Note: Note that this major increase in childcare cost was caused not directly by the pandemic, but more by the isolation of the lockdown measures instituted. For more along these lines, see concise summaries of deeply revealing news articles on the coronavirus from reliable major media sources.
Police shot and killed at least 1,055 people nationwide last year, the highest total since The Washington Post began tracking fatal shootings by officers in 2015 – underscoring the difficulty of reducing such incidents despite sustained public attention to the issue. The new count is up from 1,021 shootings the previous year and 999 in 2019. The total comes amid a nationwide spike in violent crime. Despite setting a record, experts said the 2021 total was within expected bounds. Police have fatally shot roughly 1,000 people in each of the past seven years, ranging from 958 in 2016 to last year's high. The number of fatal police shootings ... suggests officers' behavior has not shifted significantly since The Post began collecting data. Advocacy for policing overhauls has intensified since the murder of George Floyd by a Minneapolis police officer in 2020. More than 400 bills were introduced in state legislatures last year to address officers' use of force. Police departments increasingly partnered with mental health experts to respond to people in crisis. Cities established civilian review boards for use-of-force incidents. None of it decreased the number of people shot and killed by officers last year. Last year, all but 15 percent of people shot and killed by officers were armed. Ninety-four percent were men. Roughly 14 percent had known mental health struggles, down from about one-fifth in the two previous years and about one-fourth in 2016 and 2015.

The cost of vaccinating the world against COVID-19 could be at least five times cheaper if pharmaceutical companies weren't profiteering from their monopolies on COVID-19 vaccines, campaigners from the People's Vaccine Alliance said today. New analysis by the Alliance shows that the firms Pfizer/BioNTech and Moderna are charging governments as much as $41 billion above the estimated cost of production. Colombia, for example, has potentially overpaid by as much as $375 million for its doses of the Pfizer/BioNTech and Moderna vaccines, in comparison to the estimated cost price. Despite a rapid rise in COVID-19 cases and deaths across the developing world, Pfizer/BioNTech and Moderna have sold over 90 percent of their vaccines so far to rich countries, charging up to 24 times the potential cost of production. Last week Pfizer/BioNTech announced it would licence a South African company to fill and package 100 million doses for use in Africa, but this is a drop in the ocean of need. Neither company have agreed to fully transfer vaccine technology and know-how with any capable producers in developing countries, a move that could increase global supply, drive down prices and save millions of lives. Analysis of production techniques for the leading mRNA type vaccines produced by Pfizer/BioNTech and Moderna â₏•which were only developed thanks to public funding to the tune of $8.3 billionâ₏• suggest these vaccines could be made for as little as $1.20 a dose.

Last year, racing to develop a vaccine in record time, Pfizer made a big decision: Unlike several rival manufacturers, which vowed to forgo profits on their shots during the Covid-19 pandemic, Pfizer planned to profit on its vaccine. On Tuesday, the company announced just how much money the shot is generating. The vaccine brought in $3.5 billion in revenue in the first three months of this year, nearly a quarter of its total revenue, Pfizer reported. The vaccine was, far and away, Pfizer's biggest source of revenue. The company did not disclose the profits it derived from the vaccine, but it reiterated its previous prediction that its profit margins on the vaccine would be in the high 20 percent range. That would translate into roughly $900 million in pretax vaccine profits in the first quarter. The company's vaccine is disproportionately reaching the world's rich – an outcome, so far at least, at odds with its chief executive's pledge to ensure that poorer countries "have the same access as the rest of the world" to a vaccine that is highly effective at preventing Covid-19. As of mid-April, wealthy countries had secured more than 87 percent of the more than 700 million doses of Covid-19 vaccines dispensed worldwide, while poor countries had received only 0.2 percent. Pfizer has kept the profitability of its vaccine sales opaque. The United States, for example, is paying $19.50 for each Pfizer dose. Israel agreed to pay Pfizer about $30 per dose.
Note: If Pfizer is truly concerned about global health, why are they reaping such huge profits when other companies were willing to forgo profits. And why are they not helping the economically disadvantaged countries?

Covid-19 vaccines have created at least nine new billionaires after shares in companies producing the shots soared. Topping the list of new billionaires are Moderna CEO Stéphane Bancel and Ugur Sahin, the CEO of BioNTech, which has produced a vaccine with Pfizer (PFE). Both CEOs are now worth around $4 billion, according to an analysis by the People's Vaccine Alliance, a campaign group that includes Oxfam, UNAIDS, Global Justice Now and Amnesty International. Senior executives from China's CanSino Biologics and early investors in Moderna have also become billionaires on paper as shares skyrocketed, partly in expectation of profits earned from Covid vaccines, which also bode well for the companies' future prospects. Moderna's share price has gained more than 700% since February 2020, while BioNTech has surged 600%. CanSino Biologics' stock is up about 440% over the same period. The company's single-dose Covid-19 vaccine was approved for use in China in February. Activists said the wealth generation highlighted the stark inequality that has resulted from the pandemic. The nine new billionaires are worth a combined $19.3 billion. According to the World Health Organization, 87% of vaccine doses have gone to high- or upper middle-income countries, while low income countries have received just 0.2%. In a paper published Friday, IMF chief economist Gita Gopinath said that vaccinating 60% of the global population by mid-2022 would cost just $50 billion.

This year, Pfizer expects to bring in $36 billion from worldwide sales of its COVID-19 vaccine. That would shatter the previous record in annual sales for a single pharmaceutical product - about $20 billion for the anti-inflammatory drug Humira - and make the Pfizer vaccine the bestselling pharmaceutical product ever. Moderna will deliver fewer doses but is still expecting up to $18 billion in sales for the year for its COVID-19 vaccine. Humira, has been ... churning out tens of billions of dollars a year for multiple years on end. And it's not entirely clear that the mRNA vaccines will do that. Just because Pfizer and Moderna are selling billions of doses now doesn't mean that will last forever. The vaccines could work so well they eliminate the need for further boosters, though it's also possible COVID shots could become routine, like flu shots. The uncertainty puts a premium on maximizing sales now. Any vaccine manufacturer is going to realize that there's a risk that they're going to have a very short lifecycle. Moderna got a lot of government funding, offsetting costs and minimizing risks. But the COVID-19 vaccine is its only product on the market. Pfizer, on the other hand, didn't accept early government investment and took on a lot of those upfront costs itself. But it has dozens of other products in its portfolio that it makes and will continue to make once the pandemic ends.

Did you ever feel your own shoulders relax when you saw a friend receive a shoulder massage? For those of you who said "yes," congratulations, your brain is using its power to create a "placebo effect." For those who said "no," you're not alone, but thankfully, the brain is trainable. Since the 1800s, the word placebo has been used to refer to a fake treatment, meaning one that does not contain any active, physical substance. Today, placebos play a crucial role in medical studies in which some participants are given the treatment containing the active ingredients of the medicine, and others are given a placebo. These types of studies help tell researchers which medicines are effective, and how effective they are. Surprisingly, however, in some areas of medicine, placebos themselves provide patients with clinical improvement. Research suggests that the placebo effect is caused by positive expectations, the provider-patient relationship and the rituals around receiving medical care. Depression, pain, fatigue, allergies, irritable bowel syndrome, Parkinson's disease and even osteoarthritis of the knee are just a few of the conditions that respond positively to placebos. In addition to the ever-increasing body of evidence surrounding their effectiveness, placebos offer multiple benefits. They have no side effects. They are cheap. They are not addictive. They provide hope when there might not be a specific chemically active treatment available. They mobilize a person's own ability to heal through multiple pathways.

President Biden became the first sitting president to give extensive comments supporting the right to repair and acknowledging the anticompetitive practices of electronics manufacturers that have spent the last decade creating repair monopolies and making it difficult for consumers to fix the things they own. At a cabinet meeting Monday, Biden gave an update on the executive order he issued last year that directed the Federal Trade Commission to create right to repair rules that would enforce against anticompetitive practices. "Too many areas, if you own a product, from a smartphone to a tractor, you don't have the freedom to choose how or where to repair that item you purchased," Biden added. "It's broke. Well, what do I do about it if it's broke, you had to go to the dealer and you had to pay the dealer's cost, the dealer's price. If you tried to fix it yourself, some manufacturers actually would void the warranty." Biden was referring here to practices by John Deere and Apple, as well as by video game console manufacturers, who as Motherboard reported violate the Magnusson-Moss Warranty Act with "Warranty Void if Removed" stickers. Biden ... also took credit for recent moves from Amazon and Microsoft that will, in theory, make it easier for people to gain access to repair parts and manuals for their devices. "It's going to make it easy for millions of Americans to repair their electronics instead of paying an arm and a leg to repair or just throwing a device out."

Mark Cuban has opened up a new online pharmacy to help make generic drugs more affordable. The Mark Cuban Cost Plus Drug Company (MCCPDC) officially launched last week, claiming to offer the "lowest prices on 100 lifesaving prescriptions, according to a press release. The company is able to offer lower prices because it's a registered pharmaceutical wholesaler, meaning MCCPDC can "bypass middlemen and outrageous markups," per the press release. "The pharmacy's prices reflect actual manufacturer prices plus a flat 15% margin and pharmacist fee," the press release states. The company also "refuses to pay spread prices" to pharmacy benefits managers, which manage prescription drug benefits on behalf of health insurers. One of the medications available is Imatinib, a leukemia treatment that has a retail price of $9,657 a month and costs around $120 a month with a common voucher, per the press release. However, the MCCPDC offers a steep discount, making the drug available for $47 per month. Two other notable prescriptions available at a significantly reduced price are Mesalamine, used for ulcerative colitis treatment, as well as gout treatment drug Colchicine. "Not everyone sets the goal of being the lowest cost producer and provider," the billionaire [said]. "My goal is to make a profit while maximizing impact." "We will do whatever it takes to get affordable pharmaceuticals to patients," CEO Alex Oshmyansky said.

Previous infection with the coronavirus appeared to provide stronger protection against the Delta variant than did vaccination in a large sample of patients, the Centers for Disease Control and Prevention reported. Scientists analyzed testing, surveillance and immunization data from the [New York and California] to gauge the level of protection offered by vaccines and previous infection. During the week beginning May 30, 2021, vaccinated people who had not experienced Covid had the lowest risk of coronavirus infection and hospitalization, followed by unvaccinated people who had been previously diagnosed with Covid. By the week beginning Oct. 3, however, vaccinated people with a prior diagnosis fared best against the Delta variant. Unvaccinated people with a history of Covid also had lower rates of infection and hospitalization than those protected by vaccines alone. Waning of vaccine-derived immunity may explain why vaccinated people were less protected from infection with the Delta variant than those who had a prior diagnosis. A recent study of employees at the Cleveland Clinic suggested that ... vaccination does not add much benefit to a prior bout for the first many months.
Note: The full article is strongly biased towards vaccination, yet the data shows that prior exposure to COVID often provides better protection than the vaccines, whose protection clearly wanes over time.

Like many paediatricians, Dani Dumitriu braced herself for the impact of the SARS-CoV-2 coronavirus when it first surged in her wards. She was relieved when most newborn babies at her hospital who had been exposed to COVID-19 seemed to do just fine. But hints of a more subtle and insidious trend followed close behind. Dumitriu and her team ... had more than two years of data on infant development – since late 2017, they had been analysing the communication and motor skills of babies up to six months old. Dumitriu thought it would be interesting to compare the results from babies born before and during the pandemic. The infants born during the pandemic scored lower, on average, on tests of gross motor, fine motor and communication skills compared with those born before it. It didn't matter whether their birth parent had been infected with the virus or not; there seemed to be something about the environment of the pandemic itself. Lockdowns ... have isolated many young families, robbing them of playtime and social interactions. Stressed out and stretched thin, many carers also haven't been able to provide the one-to-one time that babies and toddlers need. Worryingly, [biophysicist Sean] Deoni has found that the longer the pandemic has continued, the more deficits children have accumulated. "The magnitude is massive – it's just astonishing," Deoni says of the findings, which are now under revision in JAMA Pediatrics.

Inspired by a parasitic worm that digs its sharp teeth into its host's intestines, Johns Hopkins researchers have designed tiny, star-shaped microdevices that can latch onto intestinal mucosa and release drugs into the body. David Gracias, a professor in the Whiting School of Engineering, and gastroenterologist Florin M. Selaru, director of the Johns Hopkins Inflammatory Bowel Disease Center, led a team of researchers and biomedical engineers that designed and tested shape-changing microdevices that mimic the way the parasitic hookworm affixes itself to an organism's intestines. The "theragrippers" are made of metal and a thin, shape-changing film, then coated in heat-sensitive paraffin wax. The devices, each roughly the size of a dust speck, can potentially carry any drug and release it gradually into the body. Thousands of theragrippers can be deployed in the GI tract. When the paraffin wax coating on the grippers reaches the temperature inside the body, the devices close autonomously and clamp onto the colonic wall. The closing action causes the tiny, six-pointed devices to dig into the mucosa and remain attached to the colon, where they are retained and release their medicine payloads gradually into the body. Theragrippers, says Gracias, don't rely on electricity, wireless signals or external controls. "Instead, they operate like small, compressed springs with a temperature-triggered coating on the devices that releases the stored energy autonomously."
Note: These tiny devices are literally the size of a speck of dust. They can easily be hidden in a cotton swab and administered without a person's knowledge. Might they even be put in a vaccine and go undetected? For more along these lines, see concise summaries of deeply revealing news articles on health from reliable major media sources.
