Using the Advanced Photon Source, scientists have recreated the structure of ice formed at the center of planets like Neptune.
Neptune is the farthest planet from the sun. In our solar system, it is the fourth-largest planet by size, and third densest. It is named after the Roman god of the sea.
The discovery demonstrates a practical method to overcome current challenges in the manufacture of indium gallium nitride (InGaN) LEDs with considerably higher indium concentration, through the formation of quantum dots that emit long-wavelength light. The researchers have uncovered a new way t.
A type of group-III element nitride-based light-emitting diode (LED), indium gallium nitride (InGaN) LEDs were first fabricated over two decades ago in the 90s, and have since evolved to become ever smaller while growing increasingly powerful, efficient, and durable. Today, InGaN LEDs can be found across a myriad of industrial and consumer use cases, including signals & optical communication and data storage – and are critical in high-demand consumer applications such as solid state lighting, television sets, laptops, mobile devices, augmented (AR) and virtual reality (VR) solutions.
Ever-growing demand for such electronic devices has driven over two decades of research into achieving higher optical output, reliability, longevity and versatility from semiconductors – leading to the need for LEDs that can emit different colors of light. Traditionally, InGaN material has been used in modern LEDs to generate purple and blue light, with aluminum gallium indium phosphide (AlGaInP) – a different type of semiconductor – used to generate red, orange, and yellow light. This is due to InGaN’s poor performance in the red and amber spectrum caused by a reduction in efficiency as a result of higher levels of indium required.
Saturday on W5: experts warn the next pandemic could come sooner than you think, and that unless changes are made to industrial farming practices worldwide, it could spark a virus more deadly than COVID-19.
Barely-alive creatures, such as the slime mold pictured, are able to produce “memories” — they just store them in their physical surroundings rather than a brain. “A slime mould is not a fungus or mould, but is in fact a protist, which is really the odds and ends of the natural world that don’t fit in with the rest of our taxonomic grouping system,” said PhD student Christopher Reid who led the study.
Is it possible to know where you’ve been when you don’t have a brain? Depending on your definition of “know,” the answer may be yes. Researchers have shown that the slime mold, an organism without anything that resembles a nervous system (or, for that matter, individual cells), is capable of impressive feats of navigation. It can even link food sources in optimally spaced networks. Now, researchers have shown it’s capable of filling its environment with indications of where it has already searched for food, allowing it to “remember” its past efforts and focus its attention on routes it hasn’t explored.
Visible light is extremely important in nature. Seen by the human eye, it is the most intense light emitted by the sun to reach the earth’s surface and is an essential element for fundamental biological processes underlying life. However, it is difficult to generate coherent visible light, like the light of a laser, that is intense for a short amount of time, in the order of the femtosecond.
A research team, directed by Professor Luca Razzari of the Institut national de la recherche scientifique (INRS), has successfully achieved this goal without using a complicated system. The results of their work were recently published in Nature Photonics.

A new way to usher treatments through the protective blood-brain barrier.
The world’s largest semiconductor manufacturers—Intel, Samsung, and the Taiwan Semiconductor Manufacturing Company (TSMC)—have all announced plans to build new chip factories in the US. Everyone is bragging about those plans: American lawmakers say bringing chip manufacturing back onto US soil will strengthen national security, while the chip makers, chastened by this year’s disastrous semiconductor shortage, are diversifying their supply chains to avoid future crises.
But there’s one problem: Who will pay?
Intel, Samsung, and TSMC have all threatened to pull the plug on their US factory plans unless government subsidies are on the table. Company executives claim that if they don’t get a rich package of incentives and tax breaks, they’ll build their semiconductor factories elsewhere, effectively ending American ambitions to return chip manufacturing to its shores after ceding the bulk of the market to Taiwan in the 1990s.

The founding team at H3X have a compelling origin story. The three friends — Jason Sylvestre, Max Liben, and Eric Maciolek — formed a bond as they participarted in an engineering course regarding electric vehicles.
After their careers led them in separate directions, with each finding work in the tech and auto industries, a Department of Energy grant brought them back together to ponder how they could improve electric motors.
Their first-principles mindset and efforts have borne fruit in the form of a new electric motor that can potentially power large commercial flights.
