Did product safety laws lead to the dumbing down of science toys?

“Users should not take ore samples out of their jars, for they tend to flake and crumble and you would run the risk of having radioactive ore spread out in your laboratory.” Such was the warning that came with the Gilbert U-238 Atomic Energy Lab, a 1950s science kit that included four small jars of actual uranium. Budding young nuclear scientists were encouraged to use the enclosed instruments to measure the samples’ radioactivity, observe radioactive decay, and even go prospecting for radioactive ores. Yes, the Gilbert company definitely intended for kids to try this at home. And so the company’s warning was couched not in terms of health risk but rather as bad scientific practice: Removing the ore from its jar would raise the background radiation, thereby invalidating your experimental results.

What is Coronavirus According to the World Health Organization[i], Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV).

What is 2019 Novel Coronavirus (2019-nCoV) The 2019 Novel Coronavirus (2019-nCoV) is a new strain of coronavirus that was first identified during an investigation into an outbreak in Wuhan, China. It’s important to note that how easily a virus spreads person-to-person can vary. Some viruses are highly contagious, while other viruses are less so. Investigations are ongoing to better understand the transmissibility, severity, and other features associated with 2019-nCoV, but there are indications that person-to-person spread is occurring[ii].

Know the Coronavirus Symptoms According to the CDC, patients with confirmed 2019-nCoV infections have reported mild to severe respiratory illnesses with symptoms including:

The outbreak of the Wuhan coronavirus in central China has infected thousands and spread overseas, raising the specter of a potential global epidemic as authorities desperately try to contain it.

Since the first case was identified in early December in Wuhan, capital of Hubei province, more than 5,900 people have fallen sick and at least 132 people have died in mainland China. In addition, there are dozens of confirmed cases in 17 locations outside of mainland China, including at least five in the United States.

The number of total cases worldwide now exceeds 6,000.

Researchers at the Institut Pasteur in France have become the second monitoring team in the world to sequence the entire novel coronavirus (2019-nCoV) genome in an effort to better understand its origin and virulent properties.

Nearly 8,000 reported cases and hundreds of deaths have been reported in at least 19 countries since the outbreak began in Wuhan, China, last December, prompting the World Health Organization yesterday to declare a public health emergency after evidence of human-to-human transmission had surfaced. International healthcare experts have since prioritized research surrounding 2019-nCoV in an effort to understand and tame the global outbreak.

“Sequencing the genome of pathogens is crucial for the development of specific diagnostic tests and the identification of potential treatment options,” explained Sylvie van der Werf, director of the National Reference Center (CNR) for Respiratory Viruses at the Institut Pasteur, in a statement.

Circa 2017 Bats harbor a large diversity of coronaviruses (CoVs), several of which are related to zoonotic pathogens that cause severe disease in humans. Our screening of bat samples collected in Kenya from 2007 to 2010 not only detected RNA from several novel CoVs but, more significantly, identified sequences that were closely related to human CoVs NL63 and 229E, suggesting that these two human viruses originate from bats. We also demonstrated that human CoV NL63 is a recombinant between NL63-like viruses circulating in Triaenops bats and 229E-like viruses circulating in Hipposideros bats, with the breakpoint located near 5′ and 3′ ends of the spike (S) protein gene. In addition, two further interspecies recombination events involving the S gene were identified, suggesting that this region may represent a recombination “hot spot” in CoV genomes. Finally, using a combination of phylogenetic and distance-based approaches, we showed that the genetic diversity of bat CoVs is primarily structured by host species and subsequently by geographic distances.

Uber-flying-car-2020.

Uber aims to prove once again its intention to stay at the crest of innovation with the latest updates of its flying car concept, which it plans to launch by 2020.

In a recent video (watch below), the company depicts passengers ordering flying cabs vie their app and then taking off form a “skyport” on top of an office building.

If you are interested in superlongevity, then I have something that you must read. I have previously recommended a book by Dr. David Sinclair called Lifespan. Here I am recommending a research paper that discusses one of the critical experiments in epigenetic age reversal. Normally I would read a paper first before recommending it. However, I think this is a blockbuster, and it’s over 50 pages, so I can’t wait till my slow eyes finish before passing this on. Here is an excerpt:

Age reversal!

The primary research scientist is Yuancheng Lu.

Here’s a link to the research paper:
