A bacterium discovered in a Californian lake appears to be able to use arsenic in its molecular make-up instead of phosphorus – even incorporating the toxic chemical into its DNA. That’s significant because it goes against the general rule that all terrestrial life depends on six elements: oxygen, hydrogen, carbon, nitrogen, sulphur and phosphorus. These…
As a rule, I’m suspicious of any news article that has the world “could” in the headline, but this is certainly interesting stuff. Our existence could be coded in a finite bandwidth, like a live ultra-high-definition 3-D video. And the third dimension we know and love could be no more than a holographic projection of…

The mind boggles… Lou Gehrig might not have had Lou Gehrig’s disease. —NY Times
“I think he thinks you’re drowning,” the husband said to his wife. They had been splashing each other and she had screamed but now they were just standing, neck-deep on the sand bar. “We’re fine, what is he doing?” she asked, a little annoyed. “We’re fine!” the husband yelled, waving him off, but his captain…
I’ve been blogging about the climate change issue for some time now. Here’s the latest, which responds to the exposure of private e-mails in which a climatologist is accused of acknowledging deliberately tweaking the data in order to make a stronger environmental case. [N]ot only did British investigators clear the East Anglia scientist at the center…
Very cool little story that also involves a Frederic Church painting and newspaper archives. Following a trail that began with a 19th century painting and led to hundreds of newspaper reports, the researchers discovered that the “strange huge meteor-procession” mentioned in Whitman’s noted collection “Leaves of Grass” indeed refers to a rare procession of earth-grazing…
One of my students, who is double-majoring in new media journalism and creative writing, is spending a few weeks on a dinosaur dig in Wyoming. She’s turned her academic blog into a travel journal. So far she has written: Thermopolis in Black and White What’s in my Dino Pack? dinoTravel Time dinoTaxi-ing dinoTravel I like…
After hearing that the 16th-century astronomer Copernicus was to be reburied with honors in a Polish ceremony, I checked the Wikipedia entry. Woah! Among the great polymaths of the Renaissance, Copernicus was a mathematician, astronomer, physician, quadrilingual polyglot, classical scholar, translator, artist,[3] Catholic cleric, jurist, governor, military leader, diplomat and economist. Among his many responsibilities,…
I suppose that my face-blindness has made me the person I am. I don’t much like movies or People magazine, not because I’m above caring about movie stars, but because I don’t recognize most of them. I became an addictive reader, an author and an English professor because, in the world of words on paper,…
“Oh yeah! Scientists I’ve talked to say you cannot overestimate how important HeLa cells have been.” Yet no one in the Lacks family had been informed by Johns Hopkins of the existence of their mother’s cells, until a researcher called in the early 1970s wanting to test the family. “Henrietta’s husband basically got a phone…
Christian-based materials dominate a growing home-school education market that encompasses more than 1.5 million students in the U.S. And for most home-school parents, a Bible-based version of the Earth’s creation is exactly what they want. Federal statistics from 2007 show 83 percent of home-schooling parents want to give their children “religious or moral instruction.” Hold…
It is dangerous to use local weather events (such as a heavy or light winter) to make judgments about global climate. With that caveat, I’m blogging the following because I’ve noted a shift in the online discussion about “global warming,” or the more general “climate change”. This essay does a good job exploring the events…
With its six wheels stuck in powdery sand and two wheels no longer working, the resilient little explorer will become a fixed, immobile scientific observatory — if it can survive the harsh temperatures of the upcoming winter. —LA Times
Violent video games have triggered substantial controversy due to highly publicized incidents of youth violence that have been allegedly inspired by the content of such games. Several jurisdictions have passed legislation penalizing the distribution of violent video games to minors and used psychological research to support the justification for such laws. However, courts have consistently…
The Jurupa Oak tree first sprouted into life when much of the world was still covered in glaciers. It has stood on its windswept hillside in southern California for at least 13,000 years, making it the oldest known living organism, according to a study published today. —Independent Reading this story reminded me of a story…
I just played this Every Day the Same Dream. Simple, stark, and in places charming. I smiled and thought a little.

My wife’s theory about the Norway spiral lights is that, during a practice run, Rudolph had a bit too much eggnog, sending Santa’s sleigh into a death spiral.
