Can YOU name each of the four fossils shown in the image? 

These photos are part of the Ancient Microworlds photo collection that includes 78 splendid photographs of fossils: bit.ly/1LA094h

From jellyfish stingers to mantis shrimp appendages, it takes more than muscle to move extremely fast. Read the related article: bit.ly/1f3GxK5

As natural gas has overtaken coal as the foremost source of energy for electricity in the United States, geochemist Avner Vengosh at Duke University​ studies water quality issues posed by hydraulic fracturing (aka fracking).

He spoke with Associate Editor Katie L. Burke about new developments in his field: http://bit.ly/1WJN2DX

Why Does Nature Form Exoplanets Easily?

NASA’s +Kepler Space Telescope mission has found thousands of candidate exoplanets that are passing in front of their stars in its field of view. Of these, 361 systems of more than one planet are depicted here, along with their catalog numbers.

Hypotheses of planet formation are usually forged within two accepted paradigms: core accretion and gravitational instability. Core accretion is the “bottom-up” approach: Large objects form from smaller ones, eventually building up to exoplanets. Gravitational instability is the “top-down” method: Exoplanets form directly from larger structures in the primordial disks of gas and dust orbiting young stars. But when astrophysicists zoom in on the physical details, we find ourselves (and our hypotheses) flummoxed and, quite simply, outclassed by nature.

Lot of speculation for a blip on a gravity-space telescope screen. Jumping to conclusions.

PODCAST: Can narrative intersect with the field of medicine?

Terrence Holt, MD, of the University of North Carolina at Chapel Hill​, teaches courses on medicine and society and on the writing of autobiographical narrative. He discusses his latest book, Internal Medicine: A Doctor's Stories, that accounts the years during residency: bit.ly/1J2PHE6

In his recent book, Pieter van Dokkum’s attentive photographs reveal how dragonfly wings can resemble stained glass windows one moment, flower petals the next.

Fenella Saunders discusses the informative, spectacular Dragonflies and its clear-eyed depictions of the full span of these insects’ lives. Read her review: amsci.org/bookshelf/pub/enter-the-dragons

It’s still a debate as to whether a Star Trek style optical cloaking device—something that alters light reflection to render something invisible—would ever be physically possible. But surfaces that alter waves other than those of light could be close to reality. Such cloaking devices are meant to protect subjects by guiding potentially damaging waves around them: bit.ly/1NGsMz5

It’s not your typical Intro. Biology lecture scene: In Caryn Babaian’s class, at Bucks County Community College, students absorb concepts, such as coevolution and symbiosis, as Babaian, colored chalk in hand, draws networks of interdependent living systems in the form of a mandala.

A Paleolithic rock shelter just outside of ultra-modern Dubai, a muddy hillside cave in Laos that holds a grab-bag of bones from a prehistoric flood, and rivers that ran 200,000 years ago beneath the current-day deserts of Saudi Arabia—at sites like  these, prehistorians and anthropologists are uncovering traces of early humans where no one expected to find them. 

Senior editor Sandra Ackerman compiles the accounts of several far-flung researchers who are working to fill the geographic gaps in the story of human evolution: bit.ly/1NI0vWF
