Rich Ore Deposits Linked to Ancient Atmosphere
Volcano eruption on Reunion Island in the Indian Ocean.
Much of our planet’s mineral wealth was deposited billions of years ago when Earth’s chemical cycles were different from today’s. Using geochemical clues from rocks nearly 3 billion years old, a group of scientists including Andrey Bekker and Doug Rumble from the Carnegie Institution have made the [...]
Engineers Use Aerospace Approach to Design Wave Energy System
\
Shown is the view from the far downstream end into the test section of the U.S. Air Force Academy water tunnel.
The ocean is a potentially vast source of electric power, yet as engineers test new technologies for capturing it, the devices are plagued by battering storms, limited efficiency, and the need to be tethered to [...]
Scientists Crack Corn Code: Reference Genome of Maize, Most Important US Crop
An ear of corn on the stalk in a field ready for harvesting.
A four-year, multi-institutional effort co-led by three Cold Spring Harbor Laboratory (CSHL) scientists culminated today in publication of a landmark series of papers in the journal Science revealing in unprecedented detail the DNA sequence of maize (Zea mays). Maize, or corn, as it [...]

New on-Off ‘Switch’ Triggers and Reverses Paralysis in Animals With a Beam of Light
This tiny worm became temporarily paralyzed when scientists fed it a light-sensitive material, or “photoswitch,” and then exposed it to ultraviolet light.
In an advance with overtones of Star Trek phasers and other sci-fi ray guns, scientists in Canada are reporting development of an internal on-off “switch” that paralyzes animals when exposed to a beam of [...]
Blindness Causes Structural Brain Changes, Implying Brain Can Re-Organize Itself to Adapt
Scientists from the UCLA Department of Neurology have confirmed that blindness causes structural changes in the brain, indicating that the brain may reorganize itself functionally in order to adapt to a loss in sensory input.
Visually impaired people appear to be fearless, navigating busy sidewalks and crosswalks, safely finding their way using nothing more than a [...]
Extinct Moa Rewrites New Zealand’s History
A reconstructed image of the giant extinct moa.
The evolutionary history of New Zealand’s many extinct flightless moa has been re-written in the first comprehensive study of more than 260 sub-fossil specimens to combine all known genetic, anatomical, geological and ecological information about the unique bird lineage.
Cognitive Dysfunction Reversed in Mouse Model of Down Syndrome
Laboratory mouse.
At birth, children with Down syndrome aren’t developmentally delayed. But as they age, these kids fall behind. Memory deficits inherent in Down syndrome hinder learning, making it hard for the brain to collect experiences needed for normal cognitive development.
Harnessing Waste Heat from Laptop Computers, Cell Phones May Double Battery Time
In everything from computer processor chips to car engines to electric powerplants, the need to get rid of excess heat creates a major source of inefficiency.
In everything from computer processor chips to car engines to electric powerplants, the need to get rid of excess heat creates a major source of inefficiency. But new research points [...]
Major Advance in Organic Solar Cells
Postdoctoral student Greg Welch removing a sample from the microwave reactor.
Professor Guillermo Bazan and a team of postgraduate researchers at UC Santa Barbara’s Center for Polymers and Organic Solids (CPOS) have announced a major advance in the synthesis of organic polymers for plastic solar cells.
Exotic Electric Properties of Graphene Confirmed
Graphene layers are found in graphite flakes like those from pencil lead.
First, it was the soccer-ball-shaped molecules dubbed buckyballs. Then it was the cylindrically shaped nanotubes. Now, the hottest new material in physics and nanotechnology is graphene: a remarkably flat molecule made of carbon atoms arranged in hexagonal rings much like molecular chicken wire.
Depression as Deadly as Smoking, Study Finds
Depression is as much of a risk factor for mortality as smoking, new research has found.
A study by researchers at the University of Bergen, Norway, and the Institute of Psychiatry (IoP) at King’s College London has found that depression is as much of a risk factor for mortality as smoking.
Heart Disease Found in Egyptian Mummies
This image shows the mummy of Esankh, male, Third Intermediate Period (1070-712 BCE), undergoing CT scanning.
Hardening of the arteries has been detected in Egyptian mummies, some as old as 3,500 years, suggesting that the factors causing heart attack and stroke are not only modern ones; they afflicted ancient people, too.
Nanoparticles Used in Common Household Items Cause Genetic Damage in Mice
Titanium dioxide (TiO2) nanoparticles, found in everything from cosmetics to sunscreen to paint to vitamins, caused systemic genetic damage in mice.
Titanium dioxide (TiO2) nanoparticles, found in everything from cosmetics to sunscreen to paint to vitamins, caused systemic genetic damage in mice, according to a comprehensive study conducted by researchers at UCLA’s Jonsson Comprehensive Cancer Center.
Google ‘Image Swirl’ Organizes Online Picture Search More Naturally
A first search with Google Swirl turns up stacks of image thumbnails that users can click on to explore
Look for images of “Washington” online, and Google’s search engine may turn up a random sea of pictures showing the Washington monument, the White House, George Washington, and actor Denzel Washington. Now Google’s new “Image Swirl” feature [...]
Close-Up Movie Shows Hidden Details in the Birth of Super-Suns
Artist’s conception of the “boiling disk” surrounding the massive young stellar object known as Orion Source I. A disk of hot, ionized gas surrounds the central star, blocking our view
The constellation of Orion is a hotbed of massive star formation, most prominently in the Great Nebula that sits in Orion’s sword. The glowing gas of [...]
Right-Handed Chimpanzees Provide Clues to the Origin of Human Language
An adult male extends his right arm toward an adult female in order to greet her.
Most of the linguistic functions in humans are controlled by the left cerebral hemisphere. A study of captive chimpanzees at the Yerkes National Primate Research Center (Atlanta, Georgia), reported in the January 2010 issue of Elsevier’s Cortex, suggests that this [...]
Algae Turned Into High-Temperature Hydrogen Source
This image shows the process by which Photosystem I in thermophilic blue-green algae can be catalyzed by platinum to produce a sustainable source of hydrogen.
In the quest to make hydrogen as a clean alternative fuel source, researchers have been stymied about how to create usable hydrogen that is clean and sustainable without relying on an [...]
Ancient Weapons Dug Up by Archaeologists in England
Over 5000 worked flints came from one small area, including flint cores used for tool creation, blades, flakes and ‘debitage’
Staff at the University of Leicester Archaeological Services (ULAS) have been excited by the results from a recently excavated major Prehistoric site at Asfordby, near Melton Mowbray, Leicestershire. The Mesolithic site may date from as early [...]
Genetic Variation Linked to Individual Empathy, Stress Levels
A genetic variation may contribute to how empathetic a human is, and how that person reacts to stress.
Researchers have discovered a genetic variation that may contribute to how empathetic a human is, and how that person reacts to stress. In the first study of its kind, a variation in the hormone/neurotransmitter oxytocin’s receptor was linked [...]

Ancient Penguin DNA Raises Doubts About Accuracy of Genetic Dating Techniques
Adelie penguins have survived in Antarctica for thousands of years and are invaluable for genetic research.
Penguins that died 44,000 years ago in Antarctica have provided extraordinary frozen DNA samples that challenge the accuracy of traditional genetic aging measurements, and suggest those approaches have been routinely underestimating the age of many specimens by 200 to 600 [...]
