(Medical Xpress)—Microsoft has conducted a study aimed at learning how modern technology is impacting the attention span of people who use it. They have published their results on their own website, and claim also that they have used Sohlberg and Mateer's model of attention, which allows for providing ...

The Walhalla memorial, built by King Ludwig I of Bavaria near Regensburg in 1830-42. I took a bunch of photos both of the exterior and of the numerous busts and plaques inside that commemorate famous Germans. More details here:

"Top Ten Facts" sound like clickbait but this appears to be a very solid analysis of Tesla's new home battery. Not quite as good as early announcements claim but still very interesting.
There are a lot of details that Tesla would like to paper over in their $350/kWh (DC) announcement - so we hope that you find this analysis useful and perhaps a bit more in-depth than the first wave of articles published elsewhere.

Demonstration of acrobatics and dueling techniques in recreated 15th century armor. Full plate armor did not hinder its wearer much.

Pigeons nesting in the doorway of an old monastery, now used by the local university, just above head height. Here daddy just returned with food or twigs, didn't see clearly which.

Contrary to the headline the opah is not "truly" warm-blooded but almost: it keeps its entire body at 5°C above the surrounding water, allowing it to stay at depth while other fish must regularly return to the surface to warm up.
There’s nothing about the opah that says “fast-moving predator”. Tuna, sharks, and swordfish are fast-moving predators and accordingly, their bodies look like streamlined torpedoes. By contrast, th...

Nobody seems to make butter sculptures anymore. It's a pity.
The studies in butter created by sculptress Caroline S. Brooks, including her dairy-based depiction of the dreaming Iolanthe.

When you spray spiders with carbon nanotubes and graphene flakes they will actually integrate those materials into their spider silk, making it tougher than ever. I really hope this experiment can be reproduced, it almost sounds too good to be true...

The first article in this 1879 journal describes an automatic Tic-Tac-Toe machine, based on a mechanical table comprising all possible game positions and the best response to each.

The author mentions that "the infinite number of variations in chess renders the construction of a true chess automaton impossible." Probably still true if you wanted to keep a database of all optimal moves for all possible positions...

+Christoph Nahr  A key aspect of their algo. was "an end-game database for all positions with eight pieces or fewer." I think that this involved quite a bit of storage.
