When We're Happy, We Actively Sabotage Our Good Moods With Grim Tasks (arstechnica.com) 86

Beth Mole, writing for Ars Technica: Always keeping your house tidy and spotless may earn you the label of "neat freak" -- but "super happy" may be a more accurate tag. When people voluntarily take on unpleasant tasks such as housework, they tend to be in particularly happy states, according to a new study on hedonism. The finding challenges an old prediction by some researchers that humans can be constant pleasure-seekers. Instead, the new study suggests we might seek out fun, uplifting activities mainly when we're in bad or down moods. But when we're on the up, we're more likely to go for the dull and dreary assignments. This finding of "flexible hedonism," reported this week in The Proceedings of the National Academy of Sciences, may seem counterintuitive because it suggests we sabotage our own high spirits. But it hints at the idea that humans tend to make sensible short-term trade-offs on happiness for long-term gains. "Although our data cannot directly tell us whether regularly engaging in unpleasant activities predicts psychological and social adjustment five or 10 years down the line, a large body of work has consistently demonstrated the importance of sleeping, employment, and living in a reasonably clean and organized home on mental and physical health," according to the study authors, led by Maxime Taquet of Harvard and Jordi Quoidbach of the University Pompeu Fabra in Spain.

Cambridge Company Unveils 3D Printed "Fruit" 59

An anonymous reader writes "A Cambridge England company called Dovetailed has created the world's first 3D printed 'fruit'. They use a process of spherification to create little balls of fruit puree, which they then print to form the shape of the given fruit. Images here where you can see a 3D printed raspberry. Vaiva Kalnikait, creative director and founder of Dovetailed, said: 'We have been thinking of making this for a while. It’s such an exciting time for us as an innovation lab. Our 3D fruit printer will open up new possibilities not only to professional chefs but also to our home kitchens – allowing us to enhance and expand our dining experiences. We have re-invented the concept of fresh fruit on demand.'"

I would suspect that a computer much less powerful than Watson could be unbeatable at Wheel of Fortune. The Price is Right might be interesting--you could feed it tons of data about retail prices and not get everything. Could it extrapolate the price of one particular brand of cough drops or dishwasher from other similar products it already knows?

Also, per capita gun ownership is increasing, but percentage of individuals/households that own a firearm has been steadily dropping. Statistically, what that means is that the same group of gun owners are hoarding larger and larger collections. If you've got a concealed-carry permit and are carrying two handguns, are you twice as protected?

You can't switch to self-feeding when a cat is an adult, but if you start when they're a kitten, and they grow up never having the experience of being hungry, they won't overeat. They'll nibble just what they need throughout the day. And they leave you alone instead of begging for food. (They might still wake you up because they're bored, but that's a separate problem).

The problem is that half of the US objects to bike sharing operations solely on the ground that they too closely resemble communism.

Taxis are communist?

He meant to say, "smacks of socialism."

No, he said it right. Those who can't tell the difference between bike-sharing services and socialism also can't tell the difference between socialism and communism.
