“Why is my attention drawn to this woman?”

The ability to see Earth’s magnetic field, thought to be restricted to sea turtles and swallows and other long-distance animal navigators, may also reside in human eyes.

Tests of cryptochrome 2, a key protein component of geomagnetic perception, found that its human version restored geomagnetic orientation in cryptochrome-deficient fruit flies.

Flies are a long, long way from people, but that the protein worked at all is impressive. There’s also a whole lot of it in our eyes.

“Could humans have this cryptochrome heavily expressed in the retina as a light-sensitive magnetoreceptor?” said University of Massachusetts neuroscientist Steven Reppert, lead author of…a study. “We don’t know if the molecule will do this in the human retina, but this suggests the possibility.”

Reppert, whose laboratory specializes in the biological mechanisms underlying long-distance butterfly migration, showed three years ago that cryptochrome allowed fruit flies to geomagnetically orient themselves using light…

Many gaps still remain in cryptochrome theory, but it’s generally thought that the cryptochrome system may be active across the animal kingdom, from fish to reptiles to birds. Humans, however, were thought to be an exception. Our own cryptochrome is considered a piece of circadian machinery, part of our molecular clock rather than any optical compass.

The new study, however, suggests that cryptochrome may be more than a clock…Whether any of this is linked to high levels of cryptochrome in human eyes — and, if so, whether that quantum compass system still works for us — is completely speculative, but it’s speculation that Reppert welcomes…

Reppert himself is now concentrating on how brains read their cryptochrome compass. “At the most fundamental level, we’re interested in how cryptochrome information is transferred to the nervous system,” he said. “Nobody knows how that occurs.”

Yet. Seems like a worthwhile study. Of course, just about any and all basic research is worthwhile. If it’s basic enough – you can’t really foretell where the results will lead.

In the Republican response to last night’s presidential address to a joint session of Congress, Louisiana Gov. Bobby Jindal chided the lawmakers for earmarking “$140 million for something called volcano monitoring.” The funds he was referring to are part of the $787 billion stimulus package…some 12 percent ($98.3 billion) of the monies are set aside for transportation and infrastructure projects, including volcano monitoring and other natural disaster prevention programs.

The U.S. Geological Society (USGS) is in charge of keeping tabs on volcanoes in the U.S. and its territories. The agency is currently monitoring more than 150 of them (from Yellowstone in Wyoming to Kilauea in Hawaii), some 65 of which show signs of seismic activity and are more likely than the others to erupt (including Redoubt in Alaska and Mauna Loa in Hawaii). But USGS officials aren’t just worried about Hollywood-caliber lava blowups. Other threats include potentially deadly landslides, falling rocky ash, and inundation by toxic gases that can be triggered by volcanic eruptions.

Is volcano monitoring important?

It’s extremely important. There are obvious hazards to nearby residents. Beyond human safety, there are huge economic concerns. It’s not that eruptions can be stopped, but, like a hurricane, it’s good to know when it’s coming…

There’s a huge hazard in the air from eruption plumes. Volcanic ash is not like ash from the fireplace. It’s basically pulverized rocks and glass particles. Putting glass in a jet engine isn’t good. That’s why the monitoring in Alaska is extremely important to the aviation industry.

Looks like Republicans have an anti-science track record to maintain. We went through the same ignorance, the same pig-headed foolishness when Sarah Palin prattled about wasting money on French fruit flies.
