Life Science

Few fish can survive the immense pressure of living in the deep sea. The Mariana Trench can reach around 36,200 feet deep with pressures of over 1,000 atmosphere. Scientists have placed landers at various depths ranging from 16,400-34,750 feet along the walls of the trench and have discovered what appears to be the “World’s Deepest…

A primer in eyes

Michael Land was one of those people who totally warped my brain. I’ve been interested in science since I was a kid, but I’m embarrassed to say that I never heard a whisper about evolution in the public schools I attended. Although I read about it avidly, I came out of high school and charged…

His latest column chides the climate Cassandras, and makes a really bizarre argument. Did you know that there have been severe disruptions of human activity by non-anthropogenic climate change in the past? And if climate Cassandras are as conscientious as they claim to be about weighing evidence, how do they accommodate historical evidence of enormously…

The genetic load problem

Dan Graur has written a good summary of genetic load. It’s an important concept in population genetics, and everyone should be familiar with it…and this is a nice 2½ page summary with only a little math in it. I’ll try to summarize the summary in two paragraphs and even less math … but you should…

On the importance of luck

That paper that proposed that most cancers were due to bad luck, that is, that they were a consequence of biological factors that could not be controlled, has been surprisingly controversial. I thought it was a fairly unsurprising paper that confirmed what we already suspected, but wow, the furious pushback has been something to behold.…

Bafflingly hyperbolic

Oh, look. The creationists have been routed, and the problem of the origin of life has been solved. Would you like to learn about the brilliant new science that has creationists and the Christian right terrified? The Christian right’s obsessive hatred of Darwin is a wonder to behold, but it could someday be rivaled by…

Cancer: bad genes or bad luck?

If there is one cause of cancer, it would be genetic damage to somatic cells. So all we have to do to cure cancer is prevent all genetic damage! That’s not a very useful prescription, unfortunately; it’s rather like saying that all we have to do to prevent accidental deaths is prohibit all potential causes…

All right, I definitely want to go there. It also looks as though MBARI has a multi-barrel squid-sucker, according to this video. I want one!

A new species of frog (Limnonectes larvaepartus) has been discovered in the rain forest of Sulawesi island in Indonesia. This species challenges the grade-school wisdom that taught us: ‘frogs lay eggs’. It looks like textbooks will need to be revised as this is the only known exception to that rule. Study author Dr. Jimmy McGuire (University…
