Scientists age-dated a cache of stone-tipped throwing spears unearthed from Ethiopia's Gademotta Formation at 280,000 years old. This find appears to pierce the conventional story of human evolution—a narrative about modern man evolving from some pre-human type only 200,000 years ago. How will this date discrepancy be resolved?

Scientists recently ran experiments to determine what happens when excess nucleotides are present during DNA replication.¹ In normally functioning living things, each newly formed cell receives all the freshly minted DNA it needs. But DNA copying (replication) requires manufacturing a new chromosome based on the template of an existing one—a complicated task.

Archaeologists uncovered the remains of a well-maintained and well-built British road beneath an ancient Roman road in 2011. This evidence contrasts what modern texts teach about primitive-pagan peoples inhabiting the land before Caesar conquered it and even draws into question the long ages of human development suggested by evolution.

Three researchers from the California Institute of Technology recently made a breakthrough in developing a molecule that mimics plants’ nitrogen chemistry—processes that are needed to synthesize fertilizer in a more cost-efficient way that will also avoid disasters like the April 2013 fertilizer facility explosion in West, Texas.
