Exploring Enriching Environments
"When you’re riding a bike and breathing deeply, something about the blood flowing fast and oxygen flooding your system heightens the senses — especially the sense of smell, it seems. Sometimes that’s a good thing. Not always. Here’s a map of sensational sniffs discovered along the western legs of the Burke-Gilman Trail during commutes between Shilshole and Fremont. –Brian Cantwell"

Bonobos find it easier to share than chimps do, although young chimps do just as well as bonobos of all ages. It was speculated to be because bonobos don’t have to worry about having more or less food like chimps do.
At the same time, chimps will adopt orphaned kiddos, according to a new study that found 18 cases of orphaned chimps being adopted in the wild.
Speaking of more and less, researchers based at the Institute of Neurobiology at the University of Tubingen in Germany set out to see whether rhesus monkeys could learn and flexibly apply the greater-than and less-than rule. They tested the monkeys with groups of both ordered and random dots, many of which were novel combinations to ensure that the subjects couldn’t have simply memorized them. The monkeys were cued into applying either the greater-than or less-than rule by the amount of time that elapsed between being shown the first and second group of dots.
“The monkeys immediately generalized the greater than and less than rules to numerositiesthat had not been presented previously,” the two researchers, Sylvia Bongard and Andreas Nieder, wrote. “This indicates that they understood this basic mathematical principle irrespective of the absolute numerical value of the sample displays.” In other words: “They had learned an abstract mathematical principle.”
This was interesting article about how living in larger households, or in this specific study living as a couple versus living separately after a divorce, consumes less resources overall and is better for the environment. Communes for the environment!
Speaking of groups, I found this an interesting use of group loyalty and playing with America’s usual perceptions of two supposedly polar opposite institutions, or just a cheap way for the military to get some publicity: Miss Utah, who is also an active member of the military, will be competing for the title of Miss America. What’s interesting is the military is actually paying for her training and travel to the competition.
On to brains.
One study has found that a high fever ( > 100.4) reduces symptoms of autism in children. Apparently the fever connects or stimulates nerve cells in the child’s brain. I’m curious why they only studied children (2-18) and not grown-ups. Perhaps because grown-ups don’t go to the hospital when they have a high fever.
And finally, 5-year-old chimps have better short term memories than college students, according to one study series done by researchers at Kyoto University. What was amazing to me was that the chimps were memorizing things in less than 3/10 of a second sometimes. That seems a) impossible for a human brain, and b) an adaptation to living in a setting of constant potential predation (baby chimps are tasty!). However, and even the researchers admit this, the real test would be to see how the young chimps fare against human kids.
