A New Self-Assembly Method for Fabricating Graphene Nanoribbons

New Method for Fabricating Graphene Nanoribbons Brings Scientists Closer to Revolutionizing Electronics

Scientists from UCLA and Tohoku University have discovered a new self-assembly method for producing defect-free graphene nanoribbons, bringing them one step closer to revolutionizing electronics. First characterized in 2004, graphene is a two-dimensional material with extraordinary properties. The thickness of just one carbon atom, and hundreds of times faster at conducting heat and charge than […]

Scientists Discover Protein That Can Accelerate Recovery

Scientists Discover Protein That Can Accelerate Cancer Recovery

New research from UCLA’s Jonsson Comprehensive Cancer Center reveals how a unique protein found in human bone marrow can drive stem cells to repair our blood system after an injury, providing a roadmap that could help scientists make existing radiation and chemotherapy treatments more effective for people with cancer and other blood-related diseases. Led by […]

Small-Scale Jets from the Solar Chromosphere Are Possible Sources of the Solar Wind

Astronomers Detect Sources of the Solar Wind

In a newly published study, astronomers from the Harvard-Smithsonian Center for Astrophysics reveal the detection of intermittent, small-scale jets from the solar chromosphere and their possible contribution to the stellar wind. The solar chromosphere is the region between the Sun’s surface and its hot, million-degree corona. Within this complex interface zone, only a few thousand […]

Chandra Celebrates a Decade and a Half in Space

Chandra Archive Images

To celebrate Chandra’s decade and a half in space, a variety of composite images have been released from Chandra’s archive. Every year, NASA’s Chandra X-ray Observatory looks at hundreds of objects throughout space to help expand our understanding of the Universe. Ultimately, these data are stored in the Chandra Data Archive, an electronic repository that […]

Fermi Detects Hints of Starquakes in Magnetar ‘Storm’

Fermi Discovers Signs of Starquakes in Magnetar Storm

Using data from NASA’s Fermi Gamma-ray Space Telescope, astronomers have discovered underlying signals related to the rapid-fire “storm” of high-energy blasts detected in 2009 from a highly magnetized neutron star. Such signals were first identified during the fadeout of rare giant flares produced by magnetars. Over the past 40 years, giant flares have been observed […]

Certain Peptides Exposed to UV Radiation Transition to More Reactive Triplet Quantum States

Peptides Exposed to UV Radiation Transition to More Reactive Triplet Quantum States

New research shows that certain peptides degrade under UV light by first passing through a triplet quantum state, a reactive arrangement that can cause greater damage than fragmentation alone. The most obvious effects of too much sun exposure are cosmetic, like wrinkled and rough skin. Some damage, however, goes deeper—ultraviolet light can damage DNA and […]

Hearing Restored in Noise-Deafened Mice

Scientists Restore Hearing in Mice

Using advanced tools to boost the production of a key protein in the ears of mice, a team of scientists has restored the hearing of mice partly deafened by noise. By demonstrating the importance of the protein, called NT3, in maintaining communication between the ears and brain, these new findings pave the way for research […]

Research Shows Black Holes Can Block the Formation of New Stars

Study Reveals Black Holes Can Block the Formation of New Stars

A new study from Johns Hopkins University reveals that massive black holes spewing out radio-frequency-emitting particles at near-light speed can block formation of new stars in aging galaxies, providing crucial new evidence that it is these jets of “radio-frequency feedback” streaming from mature galaxies’ central black holes that prevent hot free gas from cooling and […]

New Optical Device to Speed the Search for Earth-Like Exoplanets

New Optical Device Should Speed the Search for Earth-Like Exoplanets

A new laser-based technology known as the green astro-comb will allow astronomers to determine whether distant exoplanets they discover are rocky Earth-like worlds or less dense gas giants like Jupiter. Astronomers Chih-Hao Li and David Phillips of the Harvard-Smithsonian Center for Astrophysics want to rediscover Venus—that familiar, nearby planet stargazers can see with the naked […]

A Cost-Effective Treatment for Salty Water from Fracked Wells

Electrodialysis Can Provide Cost Effective Treatment of Salty Well Water

A newly published study reveals how electrodialysis can provide cost-effective treatment of salty water from oil and gas wells. The boom in oil and gas produced through hydraulic fracturing, or fracking, is seen as a boon for meeting U.S. energy needs. But one byproduct of the process is millions of gallons of water that’s much […]

First Resolved Image of the Nucleus of a Long-Period Comet

New NASA MRO Images of Comet Siding Spring

NASA’s Mars Reconnaissance Orbiter has captured new images of comet C/2013 A1 Siding Spring, resulting in the first resolved image of the nucleus of a long-period comet. These images were taken of comet C/2013 A1 Siding Spring by NASA’s Mars Reconnaissance Orbiter on October 19, 2014, during the comet’s close flyby of Mars and the […]
