Intersex fish in Alabama waterways

The environment is science.

Parade magazine on Sunday January 31, 2010 published an article describing mysterious intersex fish appearing in increasing numbers in rivers in the United States.

Included in the study was the Mobile River Basin which covers most of Alabama.

One third of male smallmouth bass and one fifth of male largemouth bass exhibit both male and female sex characteristics.

"Lab studies are under way to isolate potential causes," lead author Jo Ellen Hinck says.

Katherine Baer of the nonprofit group American Rivers says, "We see what's happening to the fish, and the water they're swimming in is the water we are drinking."

The Symphony of Science

Music is science.

The Symphony of Science is a musical project headed by John Boswell whereby science and philosophy are delivered in musical form.

There have been four installments, and I am including all of them here. I hope you enjoy auto-tune. In my opinion, it gets better with each video.

The newest video, released yesterday, is the last in order on this page, and includes Carl Sagan, David Attenborough, and Jane Goodall. It is titled "The Unbroken Thread."

First, "A Glorious Dawn," featuring Carl Sagan and Stephen Hawking.



Let me stop right here and say that the mysteries and beauty of our planet rival anything seen on Pandora, in the movie Avatar, and I love that movie. That sentiment is brought out in the next video.

OK, the next video is "We are all Connected," and features Carl Sagan, Richard Feynman, Neil deGrasse Tyson, and Bill Nye.



The third video is "Our Place in the Cosmos," featuring Carl Sagan, Robert Jastrow, Richard Dawkins, Stephen Hawkins, and Michio Kaku.



Finally, "The Unbroken Thread."

The Gulf Fritillary

Butterflies are science.

I chased this little fritillary around the backyard for a while before she got comfortable enough with me to let me approach her while she was feeding.

The Gulf Fritillary is common across much of the United States, and even can be found far out over the waters of the Gulf of Mexico.


Here she lighted on this tall stem and her weight pulled it over so she was practically hanging upside-down.



She landed on a variety of flowers in the yard.

You can see the silver-white orbs and streaks below on her wings.

What's happening on Saturn???

Astronomy is science.

There is no better place to let your imagination run wild than in space. So when I came across this picture taken by the Cassini spacecraft during its exploration of Saturn, I wondered. Something is piercing the F ring of Saturn.



The blog post (on Discover) where I saw it was titled "Like the fist of an angry god," and that is a great place to begin to imagine what is really going on.

"I mean, seriously: what the hell happened here?"

I'm not a big fan of science fiction, but even I could make a story out of this, as the Saturnians might be sending a probe to try to figure out why the earthlings are destroying our own planet.

Or, as the "bad astronomer" speculates,

"Is this object on an orbit that intersects the rings so that it plunges up through them and then again down into them every time it circles Saturn? If so, how does that affect the rings overall, especially over millions of years?

"Or was this a singular event, some small object whose orbit was affected by a nearby massive moon, changing its path, putting it on a collision course with Saturn’s mighty and vast ring system?"

Here's a zoom of the event.



One of the comments on The bad astronomer suggests, "Fist? No, more likely evidence of Thor’s hammer being thrown around."



Open the link and read the post and comments. And wonder.

Robins and a plant id question

Juvenile robins are science

I was cleaning out a flower bed in the front yard last week and leaned up against a crepe myrtle to rest. The tree shook, I was unaware that there was a bird nest above me, and three robin juvies flew out. The mama and the poppa were around too, and went ballistic. Sorry birdies, I didn't know you were there.






Plant identification is science

This plant and another just like it came up among the hills of squash in the garden. None of the gardeners know what it is. It has a really pretty flower.



The leaves have an almost rubbery feel and the entire plant is covered with a sticky substance that gets on your hands.



A fruit is beginning to develop.



They think some seeds must have mixed in with the squash seeds.

Hurricane killers

Stopping hurricanes is science.

Wow, I've been away from science blogging for a while. I've been concentrating on finishing a book (writing) and another new writing opportunity.

But today's article in the Birmingham News about stopping hurricanes in their tracks is intriguing. Software wiz and zillionnaire Bill Gates is seeking patents on a gizmo that would suck the warm water from the surface and replace it with cool water from the depths.

I just hope I'm not floating in a sailboat nearby when the big suck begins.

There are other problems I see with this, but I am sure these things will be taken into account. My main concern is that the rain from tropical systems, hurricanes included, often saves the southeast from drought conditions. Now if his idea just reduces the killer storm to a tropical storm and we still get the rain, then maybe OK.

And I understand his concern that climate change may be leading to more powerful and more frequent storms. So getting ahead of the game is good.

"This type of technology is not something humankind would try as a 'Plan A' or 'Plan B, ' " he (Paul Holman) wrote. "These inventions are a 'Plan C' where humans decide that we have exhausted all of our behavior changing or alternative energy options and need to rely on mitigation technologies."

Lots of people on blogs and on al.com are noting that concern about weather patterns and heat transfer and such and are warning not to mess with Mother Nature.

47 million year old ancestor?

Fossils are Science

A 47 million year old fossil is shedding light on evolution and human ancestry. The skeleton was found in Germany. Read it here.

From that story:

"She tells so many stories. We have just started the research on this fabulous specimen," said Jorn Hurum, of the University of Oslo Natural History Museum, one of the scientists reporting the find.

She just might be our direct ancestor. Or an "aunt."
