Understanding 'Glass Relaxation' and Why It's Important for Next-Generation Displays

Display manufacturers can account for a certain level of relaxation in the glass, referring to the intermolecular rearrangement, if it's known and reproducible. But fluctuations in this relaxation behavior tend to introduce uncertainty into the manufacturing process, possibly leading to misalignment of pixels within displays. Now, researchers reports on a new modeling technique to quantify and predict glass relaxation fluctuations, important for next-generation displays.

Why Are There Different 'Flavors' of Iron Around the Solar System?

New work shows that interactions between iron and nickel under the extreme pressures and temperatures similar to a planetary interior can help scientists understand the period in our Solar System's youth when planets were forming and their cores were created.

Origin of Spooky Meteor Noises Reappraised by Sandia Researchers

Sound travels more slowly than light. Then why do sounds of meteors entering earth's atmosphere precede or accompany the sight of them? Sandia researchers believe they have an answer.

Geneseo Planetary Geologist Involved in Determining Next Mars Rover Landing Site

Nicholas Warner, assistant professor of geology, was among planetary geologists recently presenting evidence to NASA scientists on the best Mars landing sites for the next rover mission, scheduled to launch in 2020.

Molecular Phenomenon Discovered by Advanced NMR Facility

Cutting edge technology has shown a molecule self-assembling into different forms when passing between solution state to solid state, and back again - a curious phenomenon in science - says research by the University of Warwick.

Protein Structure Solved From Smallest Crystals Yet

An international team of scientists used an X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory to determine the structure of an insect virus's crystalline protein "cocoon."

Breakthrough in 'Wonder' Materials Paves Way for Flexible Tech

Gadgets are set to become flexible, highly efficient and much smaller, following a breakthrough in measuring two-dimensional 'wonder' materials by the University of Warwick.

New Method Uses Heat Flow to Levitate Variety of Objects

Although scientists have been able to levitate specific types of material, a pair of UChicago undergraduate physics students helped take the science to a new level. Third-year Frankie Fung and fourth-year Mykhaylo Usatyuk led a team of UChicago researchers who demonstrated how to levitate a variety of objects--ceramic and polyethylene spheres, glass bubbles, ice particles, lint strands and thistle seeds--between a warm plate and a cold plate in a vacuum chamber.

Lightning Sensor Launch Saturday Brings Decades of Work to Fruition

In the mid 1990s, when NASA built two identical Lightning Imaging Sensors (just in case), Dr. Hugh Christian planned all along to send the flight spare into space. He just didn't expect it to take almost 20 years for that to happen.

Planeterrella Recreates Earth's Vivid Lightshows in Miniature

University of Iowa students have built a device to recreate Earth's auroras and other space phenomena in miniature. The planeterrella is the only one of its kind in Iowa and one of just a handful in the United States.

Old Rocks, Biased Data: Overcoming Challenges Studying the Geodynamo

Bias introduced through analyzing the magnetism of old rocks may not be giving geophysicists an accurate idea of how Earth's magnetic dynamo has functioned. A team led by Michigan Technological University shows there is a way to improve the methodology to get a better understanding of the planet's geodynamo.

Intergalactic Unions More Devastating Than We Thought

Scientists estimated the number of stars disrupted by solitary supermassive black holes in galactic centers formed due to mergers of galaxies containing supermassive black holes.

Researchers Pinpoint Watery Past on Mars

Researchers from Trinity College Dublin have discovered a patch of land in an ancient valley on Mars that appears to have been flooded by water in the not-too-distant past. In doing so, they have pinpointed a prime target to begin searching for past life forms on the Red Planet.

Flat-Footed Fighters

Walking on our heels, a feature that separates great apes, including humans, from other primates, confers advantages in fighting, according to a new University of Utah study published today in Biology Open. Although moving from the balls of the feet is important for quickness, standing with heels planted allows more swinging force, according to study lead author and biologist David Carrier, suggesting that aggression may have played a part in shaping our stance.

Life Under Pressure

Life can thrive in some of the most extreme environments on the planet. Microbes flourish inside hot geothermal vents, beneath the frigid ice covering Antarctica and under immense pressures at the bottom of the ocean. For these organisms to survive and function, so must the enzymes that enable them to live and grow. Now, researchers from Georgetown University have homed in on what allows particular enzymes to function under extreme pressures. The team will present its work during the Biophysical Society meeting held Feb. 11-15, 2017.

Extending VCSEL Wavelength Coverage to the Mid-Infrared

There are several important gases that are detectable with mid-infrared light, having wavelengths between 3-4 micrometers. Application-grade Vertical-cavity surface-emitting lasers (VCSELs), however, aren't yet available for this wavelength range, but the increasing need for compact, portable and affordable gas sensors is spurring demand for energy-efficient semiconductor sources of mid-IR light. Addressing this demand, a group of researchers set out to develop a concept to extend the wavelength coverage of VCSELs into this important regime.

Turning Up the Heat for Perfect (Nano)Diamonds

For use in quantum sensing, the bulk nanodiamond crystal surrounding the point defect must be highly perfect. Any deviation from perfection will adversely affect the quantum behavior of the material. Highly perfect nanodiamonds are also quite expensive and difficult to make. A cheaper alternative, say researchers, is to take defect-ridden, low-quality, commercially manufactured diamonds, and then "heal" them. In APL Materials, they describe a method to heal diamond nanocrystals under high-temperature conditions.

Black-Hole-Powered Jets Forge Fuel for Star Formation

Astronomers using ALMA have discovered a surprising connection between a supermassive black hole and the galaxy where it resides.

Princeton Plasma Physics Laboratory Receives Two Awards for Its Green Programs

The U.S. Department of Energy's Princeton Plasma Physics Laboratory has received two awards from national agencies for its green buying practices and its composting and recycling program, the latest in a long list of honors the Lab has received for its environmental programs over the past several years.
