Turtle Genome Analysis Sheds Light on Turtle Ancestry and Shell Evolution
April 28, 2013 — From which ancestors have turtles evolved? How did they get their shell? New data provides evidence that turtles are not primitive reptiles but belong to a sister group of birds and crocodiles. The ... > full story -
Competing Pathways Affect Early Differentiation of Higher Brain Structures
April 26, 2013 — A new study shows how the strength and timing of competing molecular signals during brain development has generated natural and presumably adaptive differences in a brain region known as the ... > full story -

April 25, 2013 — Pet guppies often jump out of their tanks. One such accident inspired a new study which reveals how guppies are able to jump so far, and suggests why they do ... > full story -
Periodic Bursts of Genetic Mutations Drive Prostate Cancer
April 25, 2013 — Cancer is typically thought to develop after genes gradually mutate over time, finally overwhelming the ability of a cell to control growth. But a new closer look at genomes in prostate cancer by an ... > full story -
As People Live Longer and Reproduce Less, Natural Selection Keeps Up
April 25, 2013 — In many places around the world, people are living longer and are having fewer children. But that's not all. A study of people living in rural Gambia shows that this modern-day "demographic ... > full story -
Material Loss Protects Teeth Against Fatigue Failure
April 24, 2013 — Scientists have digitally analysed modern human teeth using an engineering approach, finite element method, to evaluate the biomechanical behavior of teeth under realistic loading. They report ... > full story -
Functional Potential of Genes: Pushing the Boundaries of Transcription
April 24, 2013 — Like musicians in an orchestra who have the same musical score but start and finish playing at different intervals, cells with the same genes start and finish transcribing them at different points in ... > full story -
