Stuff below the fold

Fixing the space station with an old toothbrush and grease..
One was a modified toothbrush that was used to lubricate the inside of the bolt's housing after debris and metal shavings from inside had been removed. Another improvised instrument included a cleaning tool that had been made from wires that were bent back to form a brush, explained Kieth Johnson, lead spacewalk director at the Johnson Space Center.

Sea otters eat sea urchins, sea urchins eat kelp. Kelp processes CO2.
 Ergo Sea Otters stop global warming?
no problem, right?
Unless you are a shellfish fisherman... -

Adoption subsidies encourage adoption of special needs kids (often foster parents hesitate to adopt them because of the added expenses for their disabilities)...
But the subsidies also encourage foster parents with normal kids to delay adoption so that they adopt when the kid is older and therefore eligible for the subsidy...

 kinship foster care/adoption works best, but often is a financial hardship for the grandparents/relatives, so maybe they should be helped by subsidies too...
but, of course, a lot of the children taken in by relatives never go through the social service pipeline: the kids are dropped off or taken in my relatives (or sometimes friends) without paper work...

The Three Little Photons that might break theoretical physics.
the photons' near-simultaneous arrival indicates that space-time is smooth as Einstein suggested, rather than pixilated as modern theories require — at least down to slightly below the scale of the Planck length, a smaller scale than has ever been probed previously. The finding "comes close to proving [that space-time is smooth] for some range of parameters," Nemiroff said.
The finding, published in June in the journal Physical Review Letters, threatens to set theoretical physicists back several decades by scrapping a whole class of theories that attempt to reconcile Einstein's theory with quantum mechanics. But not everyone is ready to jettison quantum gravity. [Top 3 Questions People Ask an Astrophysicist (and Answers)]

With all the PC kerfuffle about Colombus day, why not just declare October 12th Explorer's day?
