Digital displays using H2O

The Kanazawa Station Fountain Clock displays the time using controlled fountains of water. Located just outside the gate to the city’s train station, it’s more than just a clock – the valving that forms the clock’s numeric digits is also used to spell out text messages in both Japanese and English.

Here’s a longer article about the clock: news.softpedia.com.

This photo gives an idea of how the water jets form the characters.

And, in Osaka, a different technology is being used to create images using water. “The attraction, located in the South Gate Building of the new Osaka Station City complex, is a large rectangular water display created by local firm Koei Industry. The ‘Space Printer’ emits illuminated water droplets in carefully controlled patterns to reproduce images that are stored on a PC. Founded in 1987, Koei has produced entertainment fountains and landscape displays in various cities in Japan.”  Read more, and see a vid, at www.cnet.com.

The Dangers of DNA Testing

This item is excerpted from a NYTimes Opinion article by Dr. Greg Hampikian, a professor of biology at Boise State University. Read the whole article here: www.nytimes.com.

Before you give the police a DNA sample, read an alarming new study of crime laboratories published this summer [2018], the largest study of its kind. Researchers from the National Institute of Standards and Technology gave the same DNA mixture to about 105 American crime laboratories and three Canadian labs and asked them to compare it with DNA from three suspects from a mock bank robbery. In [the] study, 74 out of 108 crime laboratories implicated an innocent person in [the] hypothetical bank robbery. The test results are troubling, especially since errors also occur in actual casework.

As DNA testing has become more sensitive, most laboratories are now able to produce profiles from anyone who may have lightly touched an object. The result is that DNA mixtures have become more common, making up about 15 percent of all evidence samples.

There are methods to reanalyze old DNA mixture data using computer programs that can help analysts correct errors, without any new lab testing. Many crime labs now have access to these programs and use them on current cases. But they could and should easily go back and re-examine old DNA mixtures to correct tragic mistakes.

 

YT Video: Frank Abagnale: “Catch Me If You Can” | Talks at Google

Verrrry Interesting. Watch it here www.youtube.com.

“His transformation from one of the world’s most notorious con men to an international cybersecurity expert trusted by the FBI has been mythologized in film and literature – but the takeaways he shares are the real deal. Frank’s contributions to the world of security are immeasurable. He has become a hero to hundreds of public and private sector organizations for his indispensable counsel and strategic insight on safeguarding information systems and combating cyber-fraud. With an eye on the latest techniques developed by high-tech criminals to deceive and defraud, Frank leaves audiences with a deep understanding of today’s evolving security landscape, and more importantly, a vision of how to make the world a safer place.”

Ten years of Large Hadron Collider discoveries are just the start of decoding the universe

This item is excerpted from this article at theconversation.com.

The most significant discovery to come from the LHC so far is the discovery of the Higgs boson, sometimes refered to as the ‘God particle, on July 4, 2012. The Higgs boson was the last remaining piece of what we call the standard model of particle physics. This theory covers all of the known fundamental particles — 17 of them — and three of the four forces through which they interact, although gravity is not yet included. The standard model is an incredibly well-tested theory. Two of the six scientists who developed the part of the standard model that predicts the Higgs boson won the Nobel Prize in 2013.

There is still lots to be understood. There are a number of questions that the standard model does not answer. For example, studies of galaxies and other large-scale structures in the universe indicate that there is a lot more matter out there than we observe. We call this dark matter since we can’t see it. The most common explanation to date is that dark matter is made of an unknown particle. Physicists hope that the LHC may be able to produce this mystery particle and study it. That would be an amazing discovery.
