Explanatory Filter in Action: Fairy Circles in Africa
June 30, 2012
The old "crop circle" craze fanned the curiosity of many, till humans were filmed making them. Now, scientists have a different circle mystery, and they're stumped.
Evolution Worked Magic in Plants
June 29, 2012
Some evolutionary papers are filled with verbs like arose, emerged, and originated. Do these convey scientific understanding, or are they veils concealing ignorance? Is it like saying "abracadabra" to say something "arose" by evolution? A recent paper about sophisticated metabolic enzymes in plants is a case in point.
Is This Plant Really 30,000 Years Old?
February 20, 2012
A plant said to be 30,000 years old has been brought to life in Russia. A team resurrected a fruit from a rodent burrow in Siberian permafrost, getting it to grow into a whole plant that produces viable seeds. This is now the oldest age claim, by an order of magnitude, for plant material made to live again. Other scientists are startled that plant material could remain viable for so long, since cells have to repair their DNA continually. Other botany news bring different problems to evolutionary theory.
Science Grab Bag

Here's a random assortment of things floating around in the science news media – some fascinating, some informative, some disgusting. We’ll let the readers decide which is which. Since it’s Friday the 13th, a day to enjoy like any other day, we’ll give you a baker’s dozen to sample.
Methuselah Seed Now a Tree
December 4, 2011
The world’s oldest viable seed is now a tree 8 feet tall. The Methuselah palm, discovered in the 1960s as a seed at the Judean fortress of Masada, sprouted in 2005 under controlled conditions. It is the oldest seed verified by radiocarbon dating to be 2,000 years old – from the time the Romans were besieging the mountain fortress built by Herod the Great.
Fungi Shed Light on Deep Biological Mysteries
November 20, 2011
Fungi are among the least studied and least understood organisms. Elevated from plants to their own kingdom in 1969, they are extremely diverse yet difficult to observe, since many species cannot be grown in the lab. The gaps in our knowledge of the fungi are being filled by new efforts to catalog them, but one of the most interesting findings may come from analysis of their genomes. A new study shows that introns (intragenic regions) are more dynamic than previously thought.
