A tidal wave of genomic information seems to wash up on shore each year. In 2014, an especially large wave - in those days long ago! - came ashore in the form of 45 entire genome sequences of birds. The relevance of these genomes and their hundreds of billions of letters of code representing all... Continue Reading →
The Mars Curiosity Rover continues to make its way through the basin of Gale Crater on Mars. I've provided periodical updates on its progress as it makes its way toward a large mountain in the center of the crater. Recently it has driven down almost 1000 feet to arrive at nearly the lowest elevation point... Continue Reading →
Can cancer become an infectious disease? Usually with think of cancer as limited to the individual in whom the cancer formed. But what if cancerous cells could infect other individuals. Here is a link to a story on the sad case of what happens when cancer "learns" to infect more than one individual: BBC News... Continue Reading →
The Ebola virus has captured headlines around the world. One of the big questions that I see being asked frequently is - where did it come from? Does it have a recent origin or has the virus been with us for a long time but simply not recognized? Clearly it didn't come into existence in... Continue Reading →
Most of us remember our first life-like encounter with dinosaurs sitting in a theater watching Jurassic Park (1993). Although dinosaurs had been very popular in picture books for many years the vivid recreation of them on the screen rekindled a sense of awe of these amazing creatures of a past age. Today, movies with depictions... Continue Reading →
There is a very recent form of fossil hunting that I have gotten to partake in to some small extent, and I can do it while sitting in front of a computer screen! With some computer skills and some knowledge of animal genomes it isn't difficult to join this hunt for fossils inside the genome of living organisms.
What do you think of when someone mentions the Jurassic or Cretaceous ages? Most likely you will immediately think of dinosaurs and other large reptiles such as pterosaurs. Maybe you think of the movie Jurassic Park, filled with dinosaurs and lush vegetation. This time has become known as the Age of the Reptiles and aptly so since... Continue Reading →
During the last ice age some 12 to 13 thousands years ago a young girl found herself wandering in caves of the Yucatan Peninsula likely looking for water. Hundreds of feet into a cave something happened and she fell in a deep pit breaking her pelvis. With no escape 100 feet down she died a lonely death. She... Continue Reading →
You might think of the asteroid belt between Jupiter and Mars as a assortment of space junk floating randomly in space. There are millions of asteroids of which more than 100,000 have been measured and mapped by astronomers. But analysis of those asteroids has shown that there are groups of asteroids that are related to one another and are referred to family members
Everyone has encountered a T. rex in books, movies or museums. Besides its size and menacing jaws one of the most striking features of a T. rex is its diminutive arms. So why were the arms of T. rex so short? There have been many hypotheses including: 1) they had no use and... Continue Reading →
Just how long can DNA survive after the death of a cell or without cellular activity to maintain itself? I addressed this question a few months ago (Young Earth Creationism and Ancient DNA) and suggested that we would learn much more in the coming year. Already we have seen multiple complete genomes from fossil bones... Continue Reading →
Last week I pointed out that the Bible provides no support for Ken Ham's contention that massive numbers of species have formed following their departure from Noah's ark 4500 years ago (YEC Biblical Evolution: I Have A Book That Says Otherwise). Now I'm following up with "observational" evidence from DNA sequences to test whether the... Continue Reading →
A story is breaking today of a significant fossil find made almost a year ago but kept under wraps until the data could be properly evaluated. What has now been revealed is that over 100 footprints were found in newly uncovered rocks along a shoreline of England. Study of these footprints has led to... Continue Reading →
Down a 43 foot vertical shaft, another 40 foot slope, and buried under thousands of cave bear, lion and lynx bones, lies the partially fossilized bones of at least 30 individual humans. Welcome to a chamber of horrors otherwise known as Sima de los Huesos (the pit of bones). This pit is but a small... Continue Reading →
Just how fast are some rocks on Mars eroding? A few months ago I asked a Martian rock that question (see: My Interview with a Martian: A Story of Origins) and I was not given a very satisfying answer. Well, that rock can be excused for being a bit confused about time given how boring... Continue Reading →
