New Evidence of a Possible Link Between Diabetes and the Hardening of Heart Valves

Study Shows High Blood Sugar Levels May Harden Heart Valves

By directly viewing the effect of high blood-sugar levels on heart-valve cell metabolism for the first time, bioengineers have found new evidence of a possible link between diabetes and the hardening of heart valves. Rice University bioengineers have found new evidence of a possible link between diabetes and the hardening of heart valves. A Rice […]

Research Shows Ancient Kangaroos Likely Preferred Walking to Hopping

Ancient Family of Sthenurine Kangaroos Likely Preferred Walking to Hopping

Based on a rigorous comparative analysis of kangaroo anatomy, biologists at Brown University reveal that the ancient family of sthenurine kangaroos likely preferred walking to hopping. Imagine that a time machine has transported you to the Australian outback 100,000 years ago. As you emerge, you see a huge kangaroo with a round rabbit-like face foraging […]

New Target Finding Mechanism Allows Microscopic Devices to Autonomously Find Their Way

New Technology Allows Microscopic Devices to Autonomously Find Their Way

Researchers from MIT have developed a new target-finding mechanism that allows microscopic devices to autonomously find their way to areas of a cell surface. Nature has developed a wide variety of methods for guiding particular cells, enzymes, and molecules to specific structures inside the body: White blood cells can find their way to the site […]

Chandra X-ray Observatory Image of PSR B1509-58: Illusions in the Cosmic Clouds

Chandra Xray Observatory Image Illusions in the Cosmic Clouds

First released in 2009, this Chandra image shows PSR B1509-58 – a spinning neutron star surrounded by a cloud of energetic particles. Pareidolia is the psychological phenomenon where people see recognizable shapes in clouds, rock formations, or otherwise unrelated objects or data. There are many examples of this phenomenon on Earth and in space. When […]

Ultra-Black Nano-Coating Applied to New 3D Solar Coronagraph

New Super Black Carbon Nanotube Coating for 3D Solar Coronagraph

NASA scientists have applied new super-black carbon-nanotube coating to a 3-D component critical for suppressing stray light in a new solar coronagraph. An emerging super-black nanotechnology that is to be tested for the first time this fall on the International Space Station will be applied to a complex, 3-D component critical for suppressing stray light […]

New Spitzer Image: Galactic Wheel of Life Shines in Infrared

Spitzer Views Galaxy NGC 1291

A newly released image from the Spitzer Space Telescope shows galaxy NGC 1291, which is located about 33 million light-years away in the constellation Eridanus. It might look like a spoked wheel or even a “Chakram” weapon wielded by warriors like “Xena,” from the fictional TV show, but this ringed galaxy is actually a vast […]

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 […]
