The First and Best Biotechnician

Mankind’s attempts at bioengineering have yet to match the precision of some techniques already found in nature: cloning, tissue culturing, and gene therapy. Recent studies have explored how these processes operate in amoebas, aphids, and parasitic wasps, respectively.


Deadly Waters No Problem for Well-Equipped Algae

Arsenic is a common toxic component in pesticides and herbicides, and one place it is found naturally is in the hot springs of Yellowstone National Park. The arsenic in the water there would be deadly to many living creatures, yet the Cyanidioschyzon algae thrive in it because they are specially equipped to detoxify arsenic through chemical modification.


'Live Evolution' Not Witnessed After All

Some science media outlets are hailing a recent study as “live evolution witnessed,” but what researchers at the Centre National de la Recherche Scientifique actually saw isn’t evolution at all. They observed, over the course of 300 generations, predator bacteria adapting to overcome certain defenses erected by its prey.


What Is a Turtle Fossil Doing in the Arctic?

A fossilized turtle shell, along with a host of lithified tropical plants and animals, has been discovered on Axel Heiberg Island in the High Canadian Arctic.1 This new find presents an enigma to those who believe that present processes are the key to interpreting the past (a view known as uniformitarianism).


The Permian Extinction: Good Science, Bad Assumptions

Ninety percent of marine and 70 percent of terrestrial creatures perished suddenly in an event variously called the Permian extinction, the Permian–Triassic (P-Tr) extinction, or the Great Dying. The calamity’s cause, referred to as the K-T event, remains unknown, even though asteroid impact has been in vogue.
