Scientists build army of 1 million microrobots that can fit inside a hypodermic needle
A four-inch wafer of silicon has been turned into an army of one million microscopic, walking robots, thanks to some clever engineering employed by researchers at Cornell University in New York. In a paper, published Wednesday in the journal Nature, a team of roboticists detail the creation of their invisible army of robots, which are less than 0.1mm in size (about the width of a human hair) and cannot be seen with the naked eye. The robots ... take advantage of an innovative, new class of actuators, which are the legs of the microrobots. Controlling movement in these tiny machines requires the researchers to shine a laser on minuscule light-sensitive circuits on their backs, which propels their four legs forward. They've been designed to operate in all manner of environments such as extreme acidity and temperatures. One of their chief purposes, the researchers say, could be to investigate the human body from the inside. The team was able to build incredibly small legs, which are connected to two different patches on the back of the robot - one for the front pair of legs, one for the back. Alternating light between the patches propels the microrobot forward. The research team were able to show the microrobots devices could fit within the narrowest hypodermic needle and thus, could be "injected" into the body. The machines aren't intelligent enough to target a diseased cell or respond to stimuli, so there's no application for this invisible army. However, the researchers said that "their capabilities can rapidly evolve."
Note: Remember that secret military projects are often 20 years or more advanced of anything made public. Could this technology have already been developed in secret projects and used in military vaccines? Yale professor Charles Morgan describes in this two-minute video (or this one) how cells injected through hypodermic needles can cause foreign substances to be manufactured in our bodies, how they can alter a person's memory, and much more. His full presentation on psycho-neurobiology and war given at West Point Military Academy is quite disturbing.
The coronavirus pandemic and corresponding lockdown made way for "one of the greatest wealth transfers in history," CNBC's Jim Cramer said. The stock market is rising as big business rebounds from state-ordered stoppage of nonessential activity, while small businesses drop like flies. Despite the ongoing economic woes, the S&P index of 500 large-cap companies, which is considered a benchmark for the stock market, is within striking distance of its levels from the start of the trading year. Since bottoming near 2,191 in March, the index is up about 42%. The tech-heavy Nasdaq 100 has recovered all of its losses from the coronavirus meltdown and set a new high. Many investors are betting on a V-shaped economic recovery, Cramer said. "I think we're looking at a V-shaped recovery in the stock market, and that has almost nothing to do with a V-shaped recovery in the economy," he said. Chapter 11 bankruptcies in May ballooned by 48% compared to a year ago. "That's that pesky real world asserting itself, but the only big bankruptcy we've seen in the stock market is Hertz," Cramer said. Cramer said it still only scratches the surface of what impact the halt in global economic activity will have on the country. The Senate on Wednesday sent a bill ... to relax rules on how businesses can spend relief funds provided by the Paycheck Protection Program. "The companies that took the money just got a big break: they only need to spend 60% on their employees to get the loans forgiven, down from the original 75%. That's important, as most small businesses fail because they can't afford to pay the rent," Cramer said.

The coronavirus pandemic caused nearly 300,000 deaths in the United States through early October, federal researchers said on Tuesday. The new tally includes not only deaths known to have been directly caused by the coronavirus, but also roughly 100,000 fatalities that are indirectly related and would not have occurred if not for the virus. The study, published by the Centers for Disease Control and Prevention, is an attempt to measure "excess deaths" – deaths from all causes that statistically exceed those normally occurring in a certain time period. The analysis highlights two disturbing trends. The researchers discovered a high percentage of excess deaths in an unexpected group: young adults in the prime of life. And the coronavirus has greatly raised deaths over all among people of color. Although the pandemic has mostly killed older Americans, the greatest percentage increase in excess deaths has occurred among adults ages 25 to 44, the analysis found. While the number of deaths among adults ages 45 to 64 increased by 15 percent, and by 24 percent among those ages 65 to 74, deaths increased 26.5 percent among those in their mid-20s to mid-40s, a group that includes millennials. People of color also had large percentage increases in excess deaths. Hispanics experienced a 54 percent increase, while Black people saw a 33 percent rise. Deaths were 29 percent above average for American Indians or Alaska Native people, and 37 percent above average for those of Asian descent.
Note: Former U.S. FDA Commissioner Scott Gottlieb voiced his concern that "a good portion of the deaths in that younger cohort were deaths due to despair. We've seen a spike in overdoses."

At least four candidates are near the finish line in the U.S. coronavirus vaccine race. A key point to note, however, is that the vaccine isn't an end-all solution to the pandemic. That's in large part because any inoculations developed now are focused on simply preventing symptoms from arising, rather than blocking out the virus altogether. The latter goal is a secondary endpoint, according to Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases. "The primary thing you want to do is that if people get infected, prevent them from getting sick, and if you prevent them from getting sick, you will ultimately prevent them from getting seriously ill," Fauci said. "What I would settle for, and all of my colleagues would settle for, is the primary endpoint to prevent clinically recognizable disease," he said. That level of protection would be the ultimate goal to diffusing the crisis, but is hard to do with companies facing an immediate demand for some sort of solution. While no vaccine is 100% effective, having a majority of the population inoculated and higher percentages of efficacy is the best to hope for. The U.K. is looking at challenge trials, which intentionally infect a smaller group of participants with the virus in an effort to test a vaccine's or treatment's efficacy. Fauci said the U.S. is not anticipating such a move because the rate of spread is so high in the country that it's sufficient enough of an environment to test the vaccine.
Note: This Bloomberg article further shows the vaccines are not designed to stop the virus. Why is the media not doing a better job of informing the public about this.
