And now for something weird...

A food sensor on your tooth! Nifty.

ScienceMag said:
Wireless sensors are ubiquitous, providing a steady stream of information on anything from our physical activity to changes occurring in the world's oceans. Now, scientists have developed a tiny form of the data-gathering tool, designed for an area that has so far escaped its reach: our teeth.

The 2-millimeter-by-2-millimeter devices (pictured) are made up of a film of polymers that detects chemicals in its environment. Sandwiched between two square-shaped gold rings that act as antennas, the sensor can transmit information on what's going on—or what's being chewed on—in our mouth to a digital device, such as a smartphone. The type of compound the inner layer detects—salt, for example, or ethanol—determines the spectrum and intensity of the radiofrequency waves that the sensor transmits. Because the sensor uses the ambient radio-frequency signals that are already around us, it doesn't need a power supply.

The researchers tested their invention on people drinking alcohol, gargling mouthwash, or eating soup. In each case, the sensor was able to detect what the person was consuming by picking up on nutrients, the researchers will report next week in Advanced Materials.

The devices could help health care and clinical researchers find links between dietary intake and health and, in the long run, allow each of us to keep track of how what we consume is affecting our bodies.

That's on the menu tonight!
I have never understood why people do not like Brussel Sprouts!!:confused:
Max.
I was kidding... I like practically everything that is edible... (haven't tried that fermented fish finnish plate, though... and I don't think I'll ever will)
My wife makes delicious steamed broccoli seasoned with a vinegar-based dressing, btw...

"Peter Dunsby (University of Cape Town) reports the detection of a very bright optical transient in the region between the Lagoon and Trifid Nebulae based on observations obtained from Cape Town on 20 March 2018, between 01:00 and 03:45 UT. The object was visible throughout the full duration of the observations and not seen when this field was observed previously (08 March 2018). The optical transients is at least first magnitude and is located at the following coordinates: RA (2000): 18h 04m 50s Declination (2000.0): -23d 29m 58s The coordinates are accurate to a few arcseconds. There is no obvious counterpart at this position on the Digital Sky Survey plates. Observations were obtained using an 80mm refractor. The attached URL show the image of this field (2.3 x 1.7 degrees, plate scale of 9 arcseconds per pixel) on 20 March 2018. The optical transient is the brightest star in the field. Further observations are strongly encouraged to establish the nature of this very bright optical transient. "

oh my, that was the funniest video i have seen in a long time, gotta love them vintage videos
speaking of which, i have a shoe box full of old vintage 8mm videos...you know they type..lol
