Hot Topic Origins Origin & Evolution of Life
The Challenge of Becoming Multi-Cellular
Topic: Origin & Evolution of Life
Summary: New research is helping scientists understand the principles behind the evolution of multicellular organisms.

Bee Swarms Could Unlock Secrets of the Human Brain
Topic: Origin & Evolution of Life
Summary: A new study on swarms of bees could teach us about how our brains work.

Why Aren't We Smarter?
Topic: Origin & Evolution of Life
Summary: A new study indicates that, due to evolutionary tradeoffs, being smarter may not be better for human beings.

Could Natural Nuclear Reactors Have Boosted Life on This and Other Planets?
Topic: Origin & Evolution of Life
Summary: Natural nuclear reactors have arisen on Earth and possibly on other planets. The radiation and energy released by these reactors would have had complex effects on any developing life.

The Dark Matter of the Genome
Topic: Origin & Evolution of Life
Summary: By studying a virulent fungus, scientists have answered the question of why a single gene could come in different lengths in different individuals. It all comes down to 'spliceosomal introns.' The study could have wider implications in understanding how genes evolve.

Supercool Water
Topic: Origin & Evolution of Life
Summary: Chemists may have solved a liquid mystery by showing how cold water can get before it absolutely must freeze: 55 degrees below zero Fahrenheit.

Earth's Most Extreme Extinction
Topic: Origin & Evolution of Life
Summary: New research has narrowed down the date of the most severe mass extinction known to have occurred on Earth. Additionally, the study has determined the rate at which extinctions occurred.

Evolutionary Biology Pioneer Lynn Margulis Has Died
Topic: Origin & Evolution of Life
Summary: Internationally renowned evolutionary biologist and author Lynn Margulis, a Distinguished University Professor of Geosciences at the University of Massachusetts Amherst and a National Medal of Science recipient, died Nov. 22 at her home in Amherst. She was 73.

A One-Two Punch Caused the K-T Mass Extinction?
Topic: Origin & Evolution of Life
Summary: A cosmic one-two punch of colossal volcanic eruptions and meteorite strikes likely caused the mass-extinction that killed the dinosaurs 65 million years ago.

Red Algae's Superior Photosynthesis
Topic: Origin & Evolution of Life
Summary: Scientist have made a step toward understanding why photosynthesis - one of the most important biological processes on Earth - is more efficient in red algae than in plants.
