After Robert Koch first separated Mycobacterium bovis from Mycobacterium tuberculosis, and seeing the success of vaccination in preventing smallpox, scientists believed that infection with bovine tuberculosis might protect against human tuberculosis.

It wasn't a linear path but after a lot of trial and error, and some fitful starts (including deaths, the kind of thing that would get a product pulled from existence in today's cancel culture, the Bacillus Calmette–Guérin (BCG) vaccine has been administered routinely to protect babies against tuberculosis since 1921.  

Today only a few countries, such as the United States and the Holland (where TB is rare) don't use it.

A new survey found that 86 percent of parents believe teens spend too much time gaming. The C.S. Mott Children's Hospital National Poll on Children's Health. also finds differences in gender. Twice as many parents say their teen boy plays video games every day compared to parents of teen girls. Teen boys are also more likely to spend three or more hours gaming.

Surveyed parents believe gaming often gets in the way of other aspects of their teen's life, such as family activities and interactions (46 percent), sleep (44 percent), homework (34 percent), friendship with non-gaming peers (33 percent) and extracurricular activities (31 percent).

Microsoft has declared they will become carbon neutral regarding their energy usage by 2030. While their details were sparse, they included electric cars, which still create emissions because 81 percent of electricity is generated using fossil fuels, and charging themselves an internal carbon tax which they would then use to invest. 

Sailors have told tales of giant tentacled sea monsters for millennia. In ancient times, it was the Kraken. In more recent work, Jules Verne delighted and terrified the public while reading 20,000 Leagues Under The Sea.

The monstrous Architeuthis dux, the giant squid, must have been terrifying to ancient mariners. They were the size of modern school buses, never a good thing when you are in a wooden trireme, with eyes as big as dinner plates and tentacles that can snatch prey 10 yards away.

During an evolutionary scale when most creatures got smaller, how did this squid get so big?
Publication of its full genome sequence may give us clues.

Since math is a language, there is no reason blind people can't learn it, but math and science textbooks in Braille require an enormous effort to produce. That means much higher cost for a small market, which means it can only be done by nonprofits on one economic end of the scale, or wealthy book companies on the other end, who want to offset their guilt at charging college students $200 for a book that should be $20 on Amazon.

Solar panel proponents rave about their solar energy. They tout how low their electricity bills are, that the utility is forced to buy energy from them at the same price they sell it, and that they are helping the planet.
