Cross-Bred Flies Reveal New Clues About How Proteins Are Regulated

Scripps Research Institute

A team from The Scripps Research Institute (TSRI) has revealed that by crossing two species of flies, they can use what they learn from the proteome of the hybrid offspring to find new clues about how proteins interact with each other

Brain Size of Human Ancestors Evolved Gradually Over 3 Million Years

University of Chicago Medical Center

Modern humans have brains that are more than three times larger than our closest living relatives, chimpanzees and bonobos. Scientists don't agree on when and how this dramatic increase took place, but new analysis of 94 hominin fossils shows that average brain size increased gradually and consistently over the past three million years.

Duplicate Genes Help Animals Resolve Sexual Conflict

University of Chicago Medical Center

Duplicate copies of a gene shared by male and female fruit flies have evolved to resolve competing demands between the sexes. New genetic analysis by researchers at the University of Chicago describes how these copies have evolved separate male- and female-specific functions that are crucial to reproduction and fertility.

Birds and Primates Share Brain Cell Types Linked to Intelligence

University of Chicago Medical Center

In a new study, published this week in the journal Current Biology, scientists from UChicago show that some neurons in bird brains form the same kind of circuitry and have the same molecular signature as cells that enable connectivity between different areas of the mammalian neocortex.

When It Comes to Extinction Risk, Body Size Matters

Santa Fe Institute

Models for extinction risk are necessarily simple. Most reduce complex ecological systems to a linear relationship between resource density and population growth—something that can be broadly applied to infer how much resource loss a species can survive.
