Detected by NASA's orbiting Kepler telescope, a newly found planet is the most Earth-like planet yet detected. Astronomers say the distant, rocky world is similar in size to our own and exists in the Goldilocks zone where it's not too hot and not too cold for life. The find, announced Thursday, excited planet hunters who have been scouring the Milky Way galaxy for years for potentially habitable places outside our solar system.

A fluctuating tilt in a planet’s orbit does not preclude the possibility of life, according to new research by a team of astronomers. In fact, sometimes it helps because such “tilt-a-worlds,” as astronomers sometimes call them, are less likely than fixed-spin planets to freeze over, as heat from their host star is more evenly distributed.
According to a new study, coupling commercially available spectral x-ray detectors with a specialized algorithm can improve the detection of uranium and plutonium in small, layered objects such as baggage. This approach enhances the detection powers of x-ray imaging and may provide a new tool to impede nuclear trafficking.
Following an upgrade of the Continuous Electron Beam Accelerator Facility at the Thomas Jefferson National Accelerator Facility, the accelerator delivered the highest-energy electron beams it has ever produced into a target, recording the first data of the 12 GeV era. The machine sent electrons around the racetrack three times, resulting in 6.11 GeV electrons at 2 nanoAmps average current for more than an hour.
A house window that doubles as a solar panel could be on the horizon, thanks to recent quantum dot work by Los Alamos National Laboratory researchers in collaboration with scientists from Univ. of Milano-Bicocca, Italy. Their project demonstrates that superior light-emitting properties of quantum dots can be applied in solar energy by helping more efficiently harvest sunlight.
For more than a quarter of a century, high-temperature superconductors have perplexed scientists who seek to understand the physical phenomena responsible for their unique properties. Thanks to a new study by Argonne National Laboratory, researchers have identified and solved at least one paradox in the behavior of high-temperature superconductors.
For nearly a century, electrophoretic deposition (EPD) has been used as a method of coating material by depositing particles of various substances onto the surfaces of various manufactured items. Since its earliest use, EPD has been used to deposit a wide range of materials onto surfaces. This process works well, but is limited. EPD can only deposit material across the entire surface and not in specific, predetermined locations, until now.
Researchers from the NIST Center for Nanoscale Science and Technology have observed electromagnetically induced transparency at room temperature and atmospheric pressure in a silicon nitride optomechanical system. This work highlights the potential of silicon nitride as a material for producing integrated devices in which mechanical vibrations can be used to manipulate and modify optical signals.
People who pack their cars and drive like Clark Griswold in National Lampoon’s “Vacation” pay a steep penalty when it comes to fuel economy, according to a report by Oak Ridge National Laboratory. Researchers tested vehicles at a variety of speeds with different configurations of load and tire inflation. While the findings were not unexpected, they serve as a reminder of how drivers can save money by taking simple measures.
Researchers at JILA in Colorado have engineered a short, flexible, reusable probe for the atomic force microscope (AFM) that enables state-of-the-art precision and stability in picoscale force measurements. Shorter, softer and more agile than standard and recently enhanced AFM probes, the JILA tips will benefit nanotechnology and studies of folding and stretching in biomolecules such as proteins and DNA.
Navy researchers have recently demonstrated sustained flight of a radio-controlled P-51 fighter replica fueled by a new gas-to-liquid process that uses seawater as carbon feedstock. The fuel is made using an innovative and proprietary electrolytic cation exchange module that separates gases from water at 92% efficiency. Catalysis converts the gases to liquid hydrocarbons.
Nanostructures half the breadth of a DNA strand could improve the efficiency of light emitting diodes (LEDs), especially in the “green gap,” a portion of the spectrum where LED efficiency plunges.
The European Space Agency is launching the first of six satellites for a new system designed to better monitor climate change, environmental disasters and catastrophes like floods, volcanic eruptions and earthquakes.
Recent research in Japan, China and U.S. has revealed through theoretical simulations that the molecular mechanism of carbon nanotube growth and hydrocarbon combustion actually share many similarities. In studies using acetylene molecules as feedstock, a highly reactive molecular intermediate was found to play an important role in both processes forming CNTs and soot, which are two distinctively different structures.
The National Institutes of Health held a scientific symposium and a dedication ceremony March 31 to April 1, 2014, to celebrate the completion of the John Edward Porter Neuroscience Research Center. This state of the art facility brings together neuroscientists from 10 institutes and centers across the NIH in an effort to spur new advances in our understanding of the nervous system in health and disease.
What makes cities in India and China so frustrating to drive in makes them ideal for saving fuel with hybrid vehicles, according to new research by scientists at Lawrence Berkeley National Laboratory. Heavy traffic, aggressive driving style and few freeways allow hybrids in these countries to deliver as much as a 50% increase in fuel savings over conventional internal combustion vehicles.
Data from satellite sensors show that during the Northern Hemisphere's growing season, the Midwest region of the United States boasts more photosynthetic activity than any other spot on Earth, according to NASA and university scientists who have figured out how to obtain plant fluorescence data from existing satellites.
Interest in oxide-based semiconductor electronics has exploded in recent years, fueled largely by the ability to grow atomically precise layers of various oxide materials. One of the most important materials in this burgeoning field is strontium titanate, a nominally nonmagnetic wide-bandgap semiconductor, and researchers have found a way to magnetize this material using light, an effect that persists for hours at a time.
A research team led by SLAC National Accelerator Laboratory scientists has uncovered a potential new route to produce thin diamond films for a variety of industrial applications, from cutting tools to electronic devices to electrochemical sensors. The scientists added a few layers of graphene to a metal support and exposed the topmost layer to hydrogen.
Joint BioEnergy Institute scientists have identified the genetic origins of a microbial resistance to ionic liquids and successfully introduced this resistance into a strain of E. coli bacteria for the production of advanced biofuels. The ionic liquid resistance is based on a pair of genes discovered in a bacterium native to a tropical rainforest in Puerto Rico.
As a planet orbits, its gravity makes its parent star wobble a tiny bit, resulting in slight color changes in the star's light due to the Doppler effect. A high-quality reference spectrum allows scientists to make a comparison to find planets. Now, NIST has made extensive new measurements of thorium, a heavy element often used in emission lamps that help provide that fixed ruler. The work has more than doubled the number of spectral lines.
Call it “homo minutus”. A team at Los Alamos National Laboratory is developing four human organ constructs (liver, heart, lung and kidney) that will work together to serve as a drug and toxicity analysis system that can mimic the actual response of human organs. Called ATHENA, for Advanced Tissue-engineered Human Ectypal Network Analyzer, the system will fit neatly on a desk.
Scientists at Brookhaven National Laboratory have made the first 3-D observations of how the structure of a lithium-ion battery anode evolves at the nanoscale in a real battery cell as it discharges and recharges. The details of this research, described in a paper published in Angewandte Chemie, could point to new ways to engineer battery materials to increase the capacity and lifetime of rechargeable batteries.
An international team led by researchers has developed a new technique for identifying gene enhancers in the genomes of humans and other mammals. Called SIF-seq, for site-specific integration fluorescence-activated cell sorting followed by sequencing, this new technique complements existing genomic tools, such as ChIP-seq (chromatin immunoprecipitation followed by sequencing), and offers some additional benefits.
Researchers at NIST have devised an idea for determining the 3-D shape of features as small as 10-nm wide. The model-based method compares data from scanning electron microscope images with stored entries in a library of 3-D shapes to find a match and to determine the shape of the sample. The work provides a powerful new way to characterize nanostructures.
A Hasselblad 500 sold over the weekend at an auction in Austria was described as being the only camera that made it to the moon and back. It was part of the equipment carried by the 1971 Apollo 15 mission. Cameras from other missions were left behind to make room for mineral samples.
