Pinpointing How Nature's Benefits Link To Human Well-Being
From Today's Issue
The things that people take from nature -- water, food, timber, inspiration, relaxation -- are so abundant, nature's benefits seem self-evident. At least until you try to quantitatively understand how and to what extent they contribute to human well-being.
Amazon River Exhales Virtually All Carbon Taken Up By Amazon Rain Forest
From the 05.22.13 Issue
Until recently people believed much of the rain forest's carbon floated down the Amazon River and ended up deep in the ocean. However, a new study has shown that bacteria digest the woody plant matter floating in the river and cause the release of huge amounts of carbon dioxide into the air.
Principles Of Ant Locomotion In Confined Spaces Could Help Robot Teams Work Underground
From the 05.21.13 Issue
Ants in confined spaces use their antennae for locomotion as well as for sensing the environment, according to scientists.
World’s Smallest Droplets
From the 05.20.13 Issue
Physicists may have created the smallest drops of liquid ever made in the lab.
Moth-Inspired Nanostructures Take The Color Out Of Thin Films
From the 05.17.13 Issue
Inspired by the structure of moth eyes, researchers have developed nanostructures that limit reflection at the interfaces where two thin films meet, suppressing the "thin-film interference" phenomenon commonly observed in nature.
Scientists Discover Oldest Evidence Of Split Between Old World Monkeys And Apes
From the 05.16.13 Issue
Two fossil discoveries from the East African Rift reveal new information about the evolution of primates.
Human Disease Leptospirosis Identified In New Species, the Banded Mongoose, In Africa
From the 05.15.13 Issue
Scientists find widespread but neglected disease is significant health threat in Botswana.
Physicists Light ‘Magnetic Fire’ To Reveal Energy’s Path
From the 05.14.13 Issue
Physicists have uncovered how energy is released and dispersed in magnetic materials in a process akin to the spread of forest fires, a finding that has the potential to deepen our understanding of self-sustained chemical reactions.

Scientists Use Crowd-Sourcing To Help Map Global Carbon Dioxide Emissions
From the 05.13.13 Issue
A first-of-its kind project aims to empower citizen scientists with a simple tool that can help climate science researchers locate all the power plants around the world and quantify their carbon dioxide emissions.
The Fluorescent Future Of Solar Cells
From the 05.10.13 Issue
Scientists have improved the ability of a promising type of solar cell to absorb light and convert it into electrical power by adding a fluorescent organic dye to the cell layer.
Astronomers Discover Surprising Clutch of Hydrogen Clouds Lurking Among Our Galactic Neighbors
From the 05.09.13 Issue
In a dark, starless patch of intergalactic space, astronomers have discovered a never-before-seen cluster of hydrogen clouds strewn between two nearby galaxies, Andromeda and Triangulum.
More Than A Good Eye: Robot Uses Arms, Location And More To Discover Objects
From the 05.08.13 Issue
Researchers have shown that a two-armed mobile robot, called HERB, can continually discover and refine its understanding of objects by taking advantage of all of the information available, including the object's location, size, shape and even whether it can be lifted.
Bats Use Blood To Reshape Tongue For Feeding
From the 05.07.13 Issue
Scientists have found that a species of bat uses blood flow to reshape its tongue while feeding. The quick dynamic action makes the tongue an effective "mop" for nectar and could even inspire new industrial designs.
Biologist Discovers New Dinosaur In China
From the 05.06.13 Issue
Fossil remains found by a biologist in northwestern China have been identified as a new species of small theropod, or meat-eating, dinosaur.
Bug's View Inspires Digital Camera's Unique Imaging Capabilities
From the 05.03.13 Issue
An insect-inspired device uses hemispherical, compound optics to capture wide, undistorted fields of view.
Bird Fossil Sheds Light On How Swift And Hummingbird Flight Came To Be
From the 05.02.13 Issue
Exceptionally well-preserved fossil feathers enable researchers to reconstruct wing shape in ways not possible with bones alone.
Research Helps Show How Turbulence Can Occur Without Inertia
From the 05.01.13 Issue
For more than a century, the field of fluid mechanics has posited that turbulence scales with inertia, and so massive things, like planes, have an easier time causing it. Now, research has shown that this transition to turbulence can occur without inertia at all.
What Happened To Dinosaurs' Predecessors After Earth's Largest Extinction 252 Million Years Ago?
From the 04.30.13 Issue
Newly discovered fossils from 10 million years after the mass extinction reveal a lineage of animals thought to have led to dinosaurs in Tanzania and Zambia. That is still millions of years before dinosaur relatives were seen in the fossil record elsewhere on Earth.
World’s Longest-Running Plant Monitoring Program Now Digitized
From the 04.29.13 Issue
Scientists at the Tumamoc Hill ecological research site have digitized 106 years of growth data on individual plants, making the information available for study by people all over the world.
Researchers Pinpoint How Trees Play Role In Smog Production
From the 04.26.13 Issue
Study finds that isoprene, a molecule that is produced and emitted by trees, once it is chemically altered via exposure to the sun, reacts with man-made nitrogen oxides to create particulate matter.
