More Evidence – of Water on Mars

As some of my valued Dear Readers may have become accustomed, every once in a while I’ll have some (mostly irreverent) posts on that Martian thing. What made me chuckle today was the cartoon of the series on “Speed Bump(s)” by cartoonist Dave Coverly.

Farmers Are Hacking Their Tractors Because of a Repair Ban

As of 2020, no right to repair law has passed in the US. But more than 20 states are considering legislation similar to Nebraska’s, and Bernie Sanders and Elizabeth Warren have both supported national right to repair legislation for farmers.

When it comes to repair, farmers have always been self reliant. But the modernization of tractors and other farm equipment over the past few decades has left most farmers in the dust thanks to diagnostic software that large manufacturers hold a monopoly over.

‘Mama’ drone saves life of endangered Israeli vulture chick

tend’s drone drops food to an orphaned vulture chick in IsraelAn endangered vulture chick stranded on a cliff ledge in the Judean desert became the unlikely poster child for the Israeli drone industry.

Griffon vultures are monogamous and increasingly rare. Hundreds of pairs could be found in the skies over Israel until the 1950s. Today, fewer than 60 pairs remain.

So, when a chick was born in February to the happy pair K74 (female) andT49 (male), conservationists were overjoyed.

WALTR2 lets iOS users bypass annoying iTunes app

http://www.backbayflats.com/images/uploads/bray073120-336.jpgiPhone users and those with other iOS devices who want to get their media files onto their gadgets without getting frustrated enough to throw them against the wall have a way to avoid that darn iTunes program all together. And, at least to me, that’s a really good thing.

There is a number of ways you can do this, getting files onto the device directly, and I found a good one that’s easy to use and, mostly, works very well.

It’s called WALTR2 which, perhaps not too surprisingly, is the sequel to WALTR, which I’ve never tried. And I used it to get nearly 128 gig of my music onto my iPhone! And more.

Datacolor's SpyderX lets you tweak your monitor at home

Datacolor's SpyderXWant to make sure your video monitor is displaying as it should?  If so, you might be interested in Datacolor’s SpyderX, a nifty tool by which you can optimize your display easily and quickly.

And it seems to work, though I’m no expert on such topics. But after having tried the Spyder X on my computer and even one of my flat panel 4K TV’s, I’m confident to say the product does work well.

Why would you care?

Well, there’s the pursuit of excellence, of getting the most out of the after-tax disposable income you’ve spent on your technology. And there’s also accuracy, if you’re a professional designer who uses colour in your work – if you specify a particular colour (Pantone colour standards etc., notwithstanding), you should do everything you can to ensure that what you see on your screen is exactly what you intended. Remember WYSIWGY?

Ultraviolet light can reduce Covid transmission indoors

One of the biggest questions facing us these days is how we can make our indoor spaces safe from Covid-19 contagion.

Studies have shown that we are far more likely to catch the virus in closed indoor spaces like offices, schools, public transport, museums and health centers rather than outdoors.

Bacteria And Dust Are World Travelers

Bacteria may travel thousands of miles through the air worldwide instead of hitching rides with people and animals.  Researchers at Rutgers University and other colleagues suggest that there must be a planet-wide mechanism that ensures the exchange of bacteria between faraway places. 1

From ocean waves to electricity: clean power for our planet

From ocean waves to electricity: clean power for our planetWhen Inna Braverman was two weeks old, the Chernobyl nuclear plant exploded. It was 1986 and the Braverman family was living just outside Kiev, well within the fallout range from the Chernobyl disaster. As baby Inna breathed in air tinged with radioactive dust, she stopped breathing.

“I went into full respiratory arrest,” Braverman explains in an emotional interview with ISRAEL21c.

Bacteria, Face Masks and Paper Money

Teeming masses of bacteria are in your mouth, on your skin, up your nose and on the surface of your eye, in your mouth, deep in your bowels, and well, just about everywhere.? These bacteria are possible sources of coronavirus.

Along with sheltering in place, social distancing and frequent hand washing, donning a cloth facial covering that envelops the nose and mouth represents one of the few tools available for curbing the spread of the coronavirus.?

Superworms digest plastic, with help from their bacterial sidekicks

Resembling giant mealworms, superworms (Zophobas atratus) are beetle larvae that are often sold in pet stores as feed for reptiles, fish and birds. In addition to their relatively large size (about 2 inches long), these worms have another superpower: They can degrade polystyrene plastic. Now, researchers reporting in ACS’ Environmental Science & Technology have linked this ability to a strain of bacteria that lives in the larvae’s gut.

Electronics for high-altitude use can get smaller and sturdier with new nanomaterials

Electronics for high-altitude use can get smaller and sturdier with new nanomaterialsWASHINGTON — As demand for higher-efficiency and smaller electronics grows, so does demand for a new generation of materials that can be printed at ever smaller dimensions. Such materials are critical to national security applications and space exploration. But materials that work well on Earth don’t always hold up well at high altitudes and in space. Scientists are now creating new metal-based nanomaterials for circuit boards that could be resistant to the high-altitude radiation encountered by electronics in aerospace equipment, fighter jets and weapon systems.

Bone proteomics could reveal how long a corpse has been underwater

Bone proteomics could reveal how long a corpse has been underwaterWhen a dead body is found, one of the first things a forensic pathologist tries to do is estimate the time of death. There are several ways to do this, including measuring body temperature or observing insect activity, but these methods don’t always work for corpses found in water. Now, researchers are reporting a mouse study in ACS’ Journal of Proteome Research showing that certain proteins in bones could be used for this determination.
