The Lead

MRI, on a molecular scale

April 21, 2014 | by Peter Reuell, Harvard Univ. | Comments

A team of scientists, led by physicist Amir Yacoby of Harvard Univ., has developed a magnetic resonance imaging (MRI) system that can produce nanoscale images, and may one day allow researchers to peer into the atomic structure of individual molecules. Though not yet precise enough to capture atomic-scale images of a single molecule, the system already has been used to capture images of single electron spins.

Unlocking a mystery of human disease in space

April 21, 2014 7:45 am | by Jessica Stoller-Conrad, Caltech | Comments

Huntington's disease is a grim diagnosis. A hereditary disorder with debilitating physical and cognitive symptoms, the disease usually robs adult patients of their ability to walk, balance and speak. More than 15 years ago, researchers revealed the disorder's likely cause—an abnormal version of the protein huntingtin; however, the mutant protein's mechanism is poorly understood, and the disease remains untreatable.

Poll: Big Bang a big question for most Americans

April 21, 2014 4:21 am | by Jennifer Agiesta - Associated Press - Associated Press | Comments

Few Americans question that smoking causes cancer. But they express bigger doubts as concepts that scientists consider to be truths get further from our own experiences and the present time, an Associated Press-GfK poll found. Americans have more skepticism than confidence in global warming, the age of the Earth and evolution and have the most trouble believing a Big Bang created the universe 13.8 billion years ago.

Easter morning delivery for space station

April 20, 2014 8:20 am | by Marcia Dunn - AP Aerospace Writer - Associated Press | Comments

Space station astronauts got a special Easter treat: a cargo ship full of supplies. The shipment arrived Sunday morning via a Dragon, versus a bunny. The SpaceX company's cargo ship, Dragon, spent two days chasing the International Space Station following its launch from Cape Canaveral. Astronauts used a robot arm to capture the capsule 260 miles above Egypt.

Hawaii is genetically engineered crop flash point

April 19, 2014 10:20 am | by Audrey Mcavoy - Associated Press - Associated Press | Comments

You can trace the genetic makeup of most corn grown in the U.S., and in many other places around the world, to Hawaii. The tiny island state 2,500 miles from the nearest continent is so critical to the nation's modern corn-growing business that the industry's leading companies all have farms here, growing new varieties genetically engineered for desirable traits like insect and drought resistance.

Researchers find 3-million-year-old landscape beneath Greenland Ice Sheet

April 18, 2014 3:15 pm | by Joshua Brown, Univ. of Vermont, and Maria-José Viñas, NASA's Earth Science News Team | Comments

Glaciers and ice sheets are commonly thought to work like a belt sander. As they move over the land they scrape off everything, including vegetation, soil and even the top layer of bedrock. So a team of university scientists and a NASA colleague were greatly surprised to discover an ancient tundra landscape preserved under the Greenland Ice Sheet, below two miles of ice.

Scientists produce thinnest feasible membrane

April 18, 2014 3:10 pm | by Fabio Bergamin, ETH Zurich | Comments

Researchers have produced a stable porous membrane that is thinner than a single nanometer. The membrane consists of two layers of graphene on which have been etched tiny pores of a precisely defined size. Extremely light and breathable, the new material could help enable a new generation of ultra-rapid filters or functional waterproof clothing.

NASA's moon-orbiting robot crashes down as planned

April 18, 2014 10:28 am | by Marcia Dunn - AP Aerospace Writer - Associated Press | Comments

NASA's robotic moon explorer, LADEE, is no more. Flight controllers confirmed Friday that the orbiting spacecraft crashed into the back side of the moon as planned, just three days after surviving a full lunar eclipse, something it was never designed to do. Researchers believe LADEE likely vaporized when it hit because of its extreme orbiting speed of 3,600 mph, possibly smacking into a mountain or side of a crater.

Impact glass stores biodata for millions of years

April 18, 2014 10:22 am | by Mark Nickel, Brown Univ. | Comments

Bits of plant life encapsulated in molten glass by asteroid and comet impacts millions of years ago give geologists information about climate and life forms on the ancient Earth. Scientists exploring large fields of impact glass in Argentina suggest that what happened on Earth might well have happened on Mars millions of years ago. Martian impact glass could hold traces of organic compounds.

The countdown is on! Final R&D 100 deadline: May 9, 2014

April 18, 2014 8:52 am | Comments

In response to interest from potential competitors we have made one final extension to the 2014 R&D 100 Awards Entry Deadline: May 9. That gives anyone with a new product three more weeks to prepare their entry. It is certainly time enough to prepare a new entry as well. Remember, a new product launched at any time in the calendar year 2013, it can be considered for the Awards.

Impurity size affects performance of emerging superconductive material

April 18, 2014 8:45 am | by Matt Shipman, News Services, North Carolina State Univ. | Comments

Research from North Carolina State Univ. finds that impurities can hurt performance, or possibly provide benefits, in a key superconductive material that is expected to find use in a host of applications, including future particle colliders. The size of the impurities determines whether they help or hinder the material’s performance.

Pocket-sized anthrax detector aids global agriculture

April 18, 2014 8:36 am | by Stephanie Holinka, Sandia National Laboratories | Comments

A credit-card-sized anthrax detection cartridge developed at Sandia National Laboratories and recently licensed to a small business makes testing safer, easier, faster and cheaper. Bacillus anthracis, the bacteria that causes anthrax, is commonly found in soils all over the world and can cause serious, and often fatal, illness in both humans and animals.

Electrically controlled polymer changes its optical properties

April 18, 2014 8:28 am | Comments

An international team of chemists from Italy, Germany and Poland have developed a polymer with unique optical and electrical properties. Components of this polymer change their spatial configuration depending on the electric potential applied. In turn, the polarization of transmitted light is affected. The new material could be used in a windows, polarization filters or chemical sensors.

Researchers predict signs of black holes swallowing stars

April 18, 2014 8:19 am | by Aaron Dubrow, National Science Foundation | Comments

Somewhere out in the cosmos an ordinary galaxy spins, seemingly at slumber. Then all of a sudden, WHAM! A flash of light explodes from the galaxy's center. A star orbiting too close to the event horizon of the galaxy's central supermassive black hole has been torn apart by the force of gravity, heating up its gas and sending out a beacon to the far reaches of the universe.

High-temperature plasmonics eyed for solar, computer innovation

April 18, 2014 8:09 am | by Emil Venere, Purdue Univ. | Comments

New plasmonic metamaterials that operate at high temperatures could radically improve solar cell performance and bring advanced computer data storage technology that uses heat to record information on a magnetic disk. The materials could make it possible to harness clouds of electrons called surface plasmons to manipulate and control light.

Surprising material could play role in saving energy

April 18, 2014 7:56 am | by Megan Fellman, Northwestern Univ. | Comments

One strategy for addressing the world’s energy crisis is to stop wasting so much energy when producing and using it, which can happen in coal-fired power plants or transportation. Nearly two-thirds of energy input is lost as waste heat. Now Northwestern Univ. scientists have discovered a surprising material that is the best in the world at converting waste heat to useful electricity.
