A Univ. of New South Wales-led research team has encoded quantum information in silicon using simple electrical pulses for the first time, bringing the construction of affordable large-scale quantum computers one step closer to reality. The team has successfully realized a new control method for future quantum computers.
Scientists have measured the subatomic intricacies of an exotic phenomenon first predicted more than 60 years ago. This so-called van Vleck magnetism is the key to harnessing the quantum quirks of topological insulators, and could lead to unprecedented electronics.
Univ. of Michigan scientists and students will build components of a giant camera that will map 30 million galaxies' worth of the universe in three dimensions. The camera is officially known as the Dark Energy Spectroscopic Instrument, abbreviated DESI, and it's designed to help answer one of the most puzzling scientific questions of our time: Why is the expansion of the universe accelerating?
You’re going to have to think very small to understand something that has the potential to be very big. A team of researchers developed a material that acts as a superhighway for ions. The material could make batteries more powerful, change how gaseous fuel is turned into liquid fuel and help power plants burn coal and natural gas more efficiently.
When a missile or meteor strikes the earth, the havoc above ground is obvious, but the details of what happens below ground are harder to see. Duke Univ. physicists have developed techniques that enable them to simulate high-speed impacts in artificial soil and sand in the lab, and then watch what happens underground close-up, in super slow motion.
Certain types of supernovae, or exploding stars, are more diverse than previously thought, a Univ. of Arizona-led team of astronomers has discovered. The results have implications for big cosmological questions, such as how fast the universe has been expanding since the Big Bang.
The step forward follows research by the Univs. of Warwick and Cambridge and the unexpected discovery of a previously unknown arrangement of molecules in plant cell walls. The researchers investigated the polymer xylan, which comprises a third of wood matter.
With rising populations and changing climate conditions, the need for resilient and reliable crops has never been greater. Nitrogen, an essential element for plant growth, is often woefully absent in heavily farmed land. Earth’s atmosphere offers an overabundance of nitrogen, but how can it be safely and sustainably transferred into the soil? Nitrogen-eating bacteria may be the answer.
An eruption of lithium at the tip of a battery's electrode, cracks in the electrode's body and a coat forming on the electrode's surface reveal how recharging a battery many times leads to its demise. Using a powerful microscope to watch multiple cycles of charging and discharging under real battery conditions, researchers have gained insight into the chemistry that clogs rechargeable lithium batteries.
When black holes tango, one massive partner spins head over heels (or in this case heels over head) until the merger is complete, according to researchers at Rochester Institute of Technology. This spin dynamic may affect the growth of black holes surrounded by accretion disks and alter galactic and supermassive binary black holes, leading to observational effects.
Our world is full of patterns, from the twist of a DNA molecule to the spiral of the Milky Way. New research from Carnegie Mellon Univ. chemists has revealed that tiny, synthetic gold nanoparticles exhibit some of nature's most intricate patterns. Unveiling the kaleidoscope of these patterns was a Herculean task, and it marks the first time that a nanoparticle of this size has been crystallized and its structure mapped out atom by atom.
While no one yet knows what's needed to build a habitable planet, it's clear that the interplay between the sun and Earth is crucial for making our planet livable: a balance between a sun that provides energy and a planet that can protect itself from the harshest solar emissions. Our sun steadily emits light, energy and a constant flow of particles called the solar wind that bathes the planets as it travels out into space.
Researchers at Chalmers Univ. of Technology have discovered that large area graphene is able to preserve electron spin over an extended period, and communicate it over greater distances than had previously been known. This has opened the door for the development of spintronics, with an aim to manufacturing faster and more energy-efficient memory and processors in computers.
Scientists have made a discovery that could dramatically improve the efficiency of batteries and fuel cells. The research involves improving the transport of oxygen ions, a key component in converting chemical reactions into electricity. The team studied a well-known material, gadolinium doped ceria, which transports oxygen ions and is currently in use as a solid-oxide fuel cell electrolyte.
A new device developed by Univ. of California, Los Angeles, engineers and doctors may eventually help scientists study the development of disease, enable them to capture improved images of the inside of cells and lead to other improvements in medical and biological research.
Lysosomes are the garbage disposals of animal cells. As the resources are limited in cells, organic materials are broken down and recycled a lot; and that’s what lysosomes do. Detecting problems with lysosomes is the focus of a new set of fluorescent probes developed by researchers at Michigan Technological Univ.
Carbon capture will play a central role in helping the nations of the world manage and reduce their greenhouse gas emissions. Many materials are being tested for the purpose of capturing carbon dioxide. But now researchers led by the Norwegian Univ. of Science and Technology have found that ordinary clay can work just as effectively as more advanced materials.
Science is evolving: It’s becoming more translational and multidisciplinary in nature. Just as science evolves, so do lab environments. Most lab environments are now designed to be more open and not just meant for one discipline—today, biologists may work next to chemists, or chemists work alongside physicists, and so on.
A vest that allows the profoundly deaf to “feel” and understand speech is under development by engineering students and their mentors at Rice Univ. and Baylor College of Medicine. Under the direction of neuroscientist David Eagleman, Rice students are refining a vest with dozens of embedded actuators that vibrate in specific patterns to represent words. The vest responds to input from a phone app that isolates speech from ambient sound.
Within the first 150 million years after our solar system formed, a giant body roughly the size of Mars struck and merged with Earth, blasting a huge cloud of rock and debris into space. This cloud would eventually coalesce and form the moon. For almost 30 years, planetary scientists have been quite happy with this explanation, with one major exception.
Just as a delicate balance of ingredients determines the tastiness of a cookie or cake, the specific ratio of metals in an alloy determines desirable qualities of the new metal, such as improved strength or lightness. A new class of alloys, called high entropy alloys, is unique in that these alloys contain five or more elements mixed evenly in near equal concentrations and have shown exceptional engineering properties.
An international team of nuclear physicists announced the first scientific results from the Cryogenic Underground Observatory for Rare Events (CUORE) experiment. CUORE is designed to confirm the existence of the Majorana neutrino, which scientists believe could hold the key to why there is an abundance of matter over antimatter. Or put another way: why we exist in this universe.
A Purdue Univ. researcher and entrepreneur is commercializing her laboratory's innovative collagen formulations that self-assemble or polymerize to form fibrils that resemble those found in the body's tissues. These collagen building blocks can be used to create customized 3-D tissue and organs outside the body to support basic biological research, drug discovery and chemical toxicity testing.
The pseudogap, a state characterized by a partial gap and loss of coherence in the electronic excitations, has been associated with many unusual physical phenomena in a variety of materials ranging from cold atoms to colossal magnetoresistant manganese oxides to high temperature copper oxide superconductors. Its nature, however, remains controversial due to the complexity of these materials and the difficulties in studying them.
When MIT senior Emma Nelson was teaching engineering classes in China in 2013, a male student remarked of her as an instructor, “I thought we were supposed to meet engineers, not women.” As she stared out at the 100 college students before her, Nelson noticed there was just one female face looking back at her.
