In 2010, the Martin Aircraft Company introduced a jetpack it called "the world's first piratical jetpack." The jetpack even won a spot in Time's Top 50 Inventions of 2010. While its development has been on since 1981, the world's first jetpack is known to have flown in 1958. It was designed by Wendell Moore, a researcher at Bells Aerosystems. Early prototypes of Wendell's jetpack could reach a height of 5 meters (16 ft) and remain airborne for three minutes. This attracted the attention of the US Army, which funded the project with $150,000. Several test flights were later done for the US Army and even for JFK himself. The army later stopped paying for more research into the project because the flight time and distance were not convincing enough. NASA also wanted to use the jetpack for their Apollo 11 mission to serve as backups in case their lunar module malfunctioned. They later changed their minds, going for the lunar rover instead. After this setback, Bell discontinued further research on the jetpack.

Full Story

To help control the spread of COVID-19, the Centers for Disease Control and Prevention has recommended getting a COVID-19 test for people who show symptoms of the disease, have come into contact with someone known to have the disease, or are in vulnerable groups. 

The most common form of testing for the novel coronavirus involves the use of a nasopharyngeal, or nasal, swab. The swab reaches deep into the back of a person’s nose and mouth to collect cells and fluids from the upper respiratory system, which can then be checked with diagnostic tests for the presence of the novel coronavirus known as SARS-CoV-2.

The testing procedure involves inserting a 6-inch-long swab into the cavity between the nose and mouth for 15 seconds and rotating it several times. The swabbing is repeated on the other side. The swab is then inserted into a container and sent to a lab for testing.

Dr. Shawn Nasseri, an ear, nose and throat surgeon based in Beverly Hills who has conducted many COVID-19 swab tests, told us in an email that the nasal swab “follows the floor of the nose and goes to where the nose meets the throat, or naso-pharynx.”

Asked if the swab test is safe, Nasseri said, “Absolutely. The biggest risk is discomfort. The rare person — 1 in thousands — passes out from being super sensitive or gets a mild nosebleed. It’s estimated that close to 40 million or more swabs have been performed safely in the U.S. alone.”

But in recent weeks, viral posts on Facebook falsely claim that the nasal swab test can cause serious health issues. One post says, “The stick deep into the nose causes damage to the hamato-encephalic barrier and damages endocrine glands. This test creates an entrance to the brain for every infection.”

The hamato-encephalic barrier, also known as the “blood-brain barrier,” protects the brain from toxins that could be present in the blood.

Dr. Yvonne Maldonado, a professor of epidemiology at the Stanford University School of Medicine, told us in an email that the Facebook claim “is not true.”

Italy, one of the eurozone’s weaker economies, received the most investment of any EU nation from Chinese companies. That was largely down to a $7.9bn deal between Pirelli and ChemChina. France was the number two country, receiving $3.6bn of investment through a string of big deals in the tourism and infrastructure sectors.

Nasseri said that “it is incredibly implausible, if not impossible, to cross the skull base and blood-brain barrier with a swab unless someone uses a rigid metal instrument and is pointing the metal object 90 degrees in the wrong direction.”

Dr. Morgan Katz, an infectious disease expert at Johns Hopkins University, told the Associated Press that the Facebook posts misunderstand what’s happening when the swab test is performed.

The Big Bang Theory is not short on geniuses. Not only is the show about highly intelligent scientists, but cast member Mayim Bialik has a Ph.D. in Neuroscience. So it should come as no surprise that the cast would want to show off their intelligence and attention to detail. In Sheldon and Leonard's apartment, there's a large white board. The two roommates use the board frequently for everything from actual work that Leonard or Sheldon has brought home, or to decide whether to eat before or after the new Spider-Man movie.
But many foresee an economic collapse, arguing that a prolonged eurozone crisis coupled with a property bubble could render vast swaths of Chinese industry unprofitable. This would reveal hidden financial vulnerabilities and feed a downward spiral. Others believe that Beijing has ample resources to avoid a crisis, but argue that, with a growth model based on infrastructure and land sales, and with exchange and interest rates rigidly controlled, it may not have all the necessary tools at its disposal.
In 2011, some seven years after the last season of Friends, over 36 million tuned into Comedy Central, a US satellite TV channel, to watch the show. The main demographic for this channel is 16 to 34 year olds, and viewing figures spiked during holidays, when extra episodes are also shown.
