Is science catching my crazy?

While I’m linking NYTimes articles, I think y’all should sit down for a lengthier read:

Watching Whales Watching Us

I never understood how any reasonable person who’d spent time with animals could deny they are conscious, aware thinkers who experience the world much as we do.  Yet science has insisted these observations are, at best, unproven, and at worst unfounded… despite science also saying, in more and more detail, that the underlying foundations of our thoughts and emotions are all found in animal brains same as in ours.

So when Star takes offense at some little thing and snarls at Pi, then a few moments later approaches her with lowered tail and gently licks her face, according to accepted science this is something other than an apology.  An apology, a concept of forgiveness, requires emotional depth science has been unwilling to believe something as “simple” as a dog might possess.

But science might be coming around.  From the article:

“Those are the kinds of things that for the longest time a scientist wouldn’t dare consider,” [Toni Frohoff] said. “But thank goodness we’ve gone through a kind of cognitive revolution when it comes to studying the intelligence and emotion of other species. In fact, I’d say now that it is my obligation as a scientist not to discount that possibility. We do have compelling evidence of the experience of grief in cetaceans; and of joy, anger, frustration and distress and self-awareness and tool use; and of protecting not just their young but also their companions from humans and other predators. So these are reasons why something like forgiveness is a possibility.”

Anyway, set down and read the whole darn thing.  Granted it’s right up my alley in particular, but it should be an interesting read even if you’re not quite so obsessed with the subject.

Article: Give a Mouse a… Cup of Coffee?

… and maybe his memory will improve.  Researchers gave Alzheimer’s-prone mice the equivalent of 5 cups of joe a day, and found it prevented and even reversed their memory loss.  See the article on Science Daily here. Caffeine did not, however, improve memory in normal, non-Alzheimer’s mice.  “This suggests that caffeine will not increase memory performance above normal levels.  Rather, it appears to benefit those destined to develop Alzheimer’s disease,” said the lead author of the study.  Although this study was done on mice, another study (article from NYTimes) suggests a similar effect on humans.

Should you start drinking more caffeine?  Well… the research is all over the place on that one. Read the rest of this entry »

Link: Endocrine Disruptors, Frogs, and YOU

Leopard Frog

Maybe you’ve heard about the increasing incidence of gender abnormalities and other mutations in frogs.  Studies suggest this is probably linked to endocrine disruptors, found in all sorts of things our civilization uses, abuses, and throws away.  If it affects frogs (as well as fish, and almost certainly other animals, but the studies aren’t there)… well, it doesn’t take a huge leap of logic to suppose it may affect us, too.

New York Times’ Nicholas D. Kristof goes over what what we know, what we’re beginning to study, and what we haven’t yet a clue about in a recent op-ed column: http://www.nytimes.com/2009/06/28/opinion/28kristof.html

Besides possible links to low sperm counts, gender abnormalities, early puberty, and several types of cancer, endocrine disruptors may even be linked to the so-called “obesity epidemic”:

“The rise in the incidence in obesity,” [the Endocrine Society] added, “matches the rise in the use and distribution of industrial chemicals that may be playing a role in generation of obesity.”
