Neanderthal-Heidelberg Distinction Blurs
June 14, 2012
"Heidelberg Man" has been a modern name imposed on certain fossil humans that have been unable to speak for themselves. Now, their bones appear to overlap with Neanderthals. But don't modern humans have Neanderthal DNA? Do the distinctions make any sense?
New Chirality Solution Proposed
May 9, 2012
It's long been a mystery why cells use one hand of two-handed molecules, like left-handed amino acids and right-handed sugars. A new proposal solves the mystery, explaining how this phenomenon called homochirality arises naturally. Wait a minute...
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.
Small Animals Show Even More Design
February 17, 2012
Your smart phone is a triumph of miniaturization. The first computers were room-filling monstrosities; now, you can hold more computing power than a Univac in the palm of your hand. In the living world, we should't despise small creatures. They can pack a lot of technology into a small space. Here are some record-setting examples of living miniatures reported recently.
OOL for Landlubbers
February 12, 2012
No part of the universal evolutionary scenario gets more overhauls than the origin of life. Some say it began in the sea, some on the land. Some say it began at the bottom of the sea; others say that is the worst place for life to get going. The latest idea favors freshwater hot springs on land.
