Corn & soy insecticides similar to nicotine found widespread in Midwest rivers -- USGS news

These are locations of sites in Iowa sampled for neonicotinoids in 2013. Watersheds for the Mississippi River and Missouri River sites are shown in the inset.Insecticides similar to nicotine, known as neonicotinoids, were found commonly in streams throughout the Midwest, according to a new USGS study. This is the first broad-scale investigation of neonicotinoid insecticides...

Dog jealousy: Study suggests primordial origins for the 'green-eyed monster'

This image depicts emotion researcher Christine Harris, professor of psychology at UC San Diego, with Samwise, one of three border collies to inspire the study on dog jealousy.This will not surprise most dog owners: Dogs can act jealous, finds a new study from the University of California, San Diego. Darwin thought so, too. But emotion researchers have...

This is a scanning electron microscope image of a fungal haustorium (<i>Blumeria graminis f. sp. hordei</i>) taken from inside the barley epidermal cell.New research at the University of Adelaide has opened the way for the development of new lines of barley with resistance to powdery mildew.

Hubble finds 3 surprisingly dry exoplanets

This is an artistic illustration of the gas giant planet HD 209458b in the constellation Pegasus. To the surprise of astronomers, they have found much less water vapor in the hot world's atmosphere than standard planet-formation models predict.Astronomers using NASA's Hubble Space Telescope have gone looking for water vapor in the atmospheres of three planets orbiting stars similar to the Sun -- and have come up nearly...

Newly discovered gut virus lives in half the world's population

ORNL study reveals new characteristics of complex oxide surfaces

An Oak Ridge National Laboratory study combined microscopy and data processing to provide an unprecedented look at the surface of a magnanite material known for its unusual properties. The resulting "distortion maps" (right) brought into view structural areas called domains that were not easily identified in the raw images (left).A novel combination of microscopy and data processing has given researchers at the Department of Energy's Oak Ridge National Laboratory an unprecedented look at the surface of a material known...

Global wildlife decline driving slave labor, organized crime

A child grabs sleep wherever possible after a long day of labor in West Africa's struggling fishery.Global decline of wildlife populations is driving increases in violent conflicts, organized crime and child labor around the world, according to a policy paper led by researchers at the University...

Earlier Stone Age artifacts found in Northern Cape of South Africa

Atomic structure of key muscle component revealed in Penn study

This is a representation of the atomic structure of tropomodulin at the minus end of the actin filament in muscle sarcomeres. Tropomodulin interacts with the first three actin subunits of the filament. The regions of tropomodulin that interact with actin are colored magenta, and the three actin subunits involved in this interaction are represented by two shades of blue, and purple for the interacting surface of the third subunit. Other subunits of the filament are colored gray. The actin filament also has two tropomyosin coiled coils bound symmetrically on each side (orange). At the minus end, tropomodulin also interacts with the tropomyosin coiled coils, and the region responsible for this interaction is colored green.Actin is the most abundant protein in the body, and when you look more closely at its fundamental role in life, it's easy to see why. It is the basis...

3-D image of Paleolithic child's skull reveals trauma, brain damage

This is a 3-D reconstruction of skull compound fracture and endocranial surface changes.Three-dimensional imaging of a Paleolithic child's skull reveals potentially violent head trauma that likely lead to brain damage, according to a study published July 23, 2014 in the open-access journal...

Discovery is key to metal wear in sliding parts

This sequence of images reveals surprising fluid-like behavior in a solid piece of metal sliding over another, forming defects leading to wear in metal parts. (Top) Two image frames of the material flow showing how these defects are spawned in the wake of the contact. (Bottom) Scanning electron microscope pictures of the corresponding wear surfaces showing a tear and a crack. Wear particles are formed when the tears and cracks detach from the surfaces.Researchers have discovered a previously unknown mechanism for wear in metals: a swirling, fluid-like microscopic behavior in a solid piece of metal sliding over another.

How honey bees stay cool

The top panel depicts the experimental hive. It shows that the high heat area, colored red, grew within three minutes of cooling and disappeared within nine minutes. The bottom panel shows how the control panel gradually dissipated heat. There, heat persisted after 18 minutes of cooling.Honey bees, especially the young, are highly sensitive to temperature and to protect developing bees, adults work together to maintain temperatures within a narrow range. Recently published research led by...
