Modern Alchemy – Turning Metal into Glass
Basic atomic structure
Metals and glass don't seem to have anything in common. Glass is generally transparent and fragile while metals are opaque and extremely strong; but under the right conditions, metals can form glass, and when they do, what results is an opaque, durable, scratch- and corrosion-resistant material that is often stronger than steel. Metallic glass is so versatile it can...
NASA finds wind shear affecting Tropical Storm Josephine
NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of Tropical Storm Josephine east of the Lesser Antilles island chain. Suomi NPP revealed that Josephine was being affected by wind shear.
Versatile new material family could build realistic prosthetics, futuristic army platforms
Nature's blueprint for the human limb is a carefully layered structure with stiff bone wrapped in layers of different soft tissue, like muscle and skin, all bound to each other perfectly. Achieving this kind of sophistication using synthetic materials to build biologically inspired robotic parts or multicomponent, complex machines has been an engineering challenge.
NASA finds wind shear making Tropical Depression 10E struggle
NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of a struggling Tropical Depression 10E in the Eastern Pacific Ocean. Wind shear is preventing the storm from intensifying into a tropical storm.
Study rewrites the recent history of productive Cascade Arc volcanoes
Volcanic eruptions in the Cascade Range of the Pacific Northwest over the last 2.6 million years are more numerous and closely connected to subsurface signatures of currently active magma than commonly thought, according to newly published research.
Traces of ancient life tell story of early diversity in marine ecosystems
If you could dive down to the ocean floor nearly 540 million years ago just past the point where waves begin to break, you would find an explosion of life—scores of worm-like animals and other sea creatures tunneling complex holes and structures in the mud and sand—where before the environment had been mostly barren.
Researchers capture footage of fluid behaving like a solid
Swansea University researchers from the College of Engineering have captured the moments a fluid reacts like a solid through a new method of fluid observation under pressurised conditions.
Native trees thrive in teak plantations and may protect the Panama Canal
Native to India, teak is the go-to species for reforestation in Central America. But teak often underperforms in the nutrient poor soils that dominate tropical landscapes. To discover if the timber value of teak plantations grown on poor soils can be increased, scientists at the Smithsonian Tropical Research Institute interplanted rosewood and amarillo, both economically valuable native tree...
Aurora mysteries unlocked with NASA's THEMIS mission
A special type of aurora, draped east-west across the night sky like a glowing pearl necklace, is helping scientists better understand the science of auroras and their powerful drivers out in space. Known as auroral beads, these lights often show up just before large auroral displays, which are caused by electrical storms in space called substorms. Previously, scientists weren't sure if auroral...
Mathematical tool helps calculate properties of quantum materials more quickly

Many quantum materials have been nearly impossible to simulate mathematically because the computing time required is too long. Now engineers have demonstrated a way to considerably reduce the computing time. This could accelerate the development of materials for energy-efficient IT technologies of the future.
Frequently used serology test may not detect antibodies that could confirm protection against reinfection of COVID-19, study shows

Two different types of detectable antibody responses in SARS-CoV-2 (COVID-19) tell very different stories and may indicate ways to enhance public health efforts against the disease, according to researchers.
Computer scientists set benchmarks to optimize quantum computer performance
- ScienceDaily
- 20/8/14 22:33
Computer scientists have shown that existing compilers, which tell quantum computers how to use their circuits to execute quantum programs, inhibit the computers' ability to achieve optimal performance. Specifically, their research has revealed that improving quantum compilation design could help achieve computation speeds up to 45 times faster than currently demonstrated.

Pregnant mother's immunity tied to behavioral, emotional challenges for kids with autism
- ScienceDaily
- 20/8/14 22:33
Children with autism born to mothers who had immune conditions during their pregnancy are more likely to have behavioral and emotional problems, a new study has found. Offspring sex may also interact with maternal immune conditions to influence outcomes, particularly in terms of a child's cognition.
AI software enables real-time 3D printing quality assessment

Researchers have developed artificial intelligence software for powder bed 3D printers that assesses the quality of parts in real time, without the need for expensive characterization equipment.
UK ministers were warned local lockdowns could fuel racial tensions
Government accused of being ‘tone deaf’ for imposing restrictions in the north of England despite warningsCoronavirus – latest updatesSee all our coronavirus coverageThe government has been accused of being “tone deaf” for its sudden introduction of further lockdown restrictions in the north of England last month shortly after being warned that local interventions could fuel racial...

If you could dive down to the ocean floor nearly 540 million years ago just past the point where waves begin to break, you would find an explosion of life -- scores of worm-like animals and other sea creatures tunneling complex holes and structures in the mud and sand -- where before the environment had been mostly barren.
A light bright and tiny: Scientists build a better nanoscale LED
- ScienceDaily
- 20/8/14 20:29
A new design for light-emitting diodes achieves a dramatic increase in brightness as well as the ability to create laser light -- characteristics that could make it valuable in a range of applications. The device shows an increase in brightness of 100 to 1,000 times over conventional submicron-sized LED designs.
Hypothesis underlying the sensitivity of mammalian auditory system overturned

A new study challenges a decades-old hypothesis on adaptation, a key feature in how sensory cells of the inner ear (hair cells) detect sound.
Watching changes in plant metabolism -- live
- ScienceDaily
- 20/8/14 20:29
Almost all life on Earth, e.g. our food and health, depend on metabolism in plants. To understand how these metabolic processes function, researchers are studying key mechanisms in the regulation of energy metabolism. A new method of in vivo biosensor technology has enabled them to monitor in real time what effects environmental changes have on the central metabolism of the model plant Arabidopsis...

The Guardian view on record-breaking weather: the heat is on | Editorial
What better time than the UK’s hottest-ever week for ministers to commit to bold climate action? The hottest week in the UK since records began offers further proof that our weather is changing. Climate change and global heating are not predictions, but facts of life that we must deal with now. Ten of the UK’s warmest-ever years have been since 2002, while the temperature of 36.4C recorded at...
