Searching for sub-eV sterile neutrinos using two highly sensitive detectors

The standard model of particle physics only accounts for 20% of matter in the universe. Physicists have theorized that the remaining 80% is made up by so-called dark matter, which consists of particles that do not emit, absorb or reflect light and thus cannot be directly observed using any existing instruments.

Physicists capture the sound of a 'perfect' fluid

For some, the sound of a "perfect flow" might be the gentle lapping of a forest brook or perhaps the tinkling of water poured from a pitcher. For physicists, a perfect flow is more specific, referring to a fluid that flows with the smallest amount of friction, or viscosity, allowed by the laws of quantum mechanics. Such perfectly fluid behavior is rare in nature, but it is thought to occur in the cores of neutron stars and in the soupy plasma of the early universe.

Mapping quantum structures with light to unlock their capabilities

A new tool that uses light to map out the electronic structures of crystals could reveal the capabilities of emerging quantum materials and pave the way for advanced energy technologies and quantum computers, according to researchers at the University of Michigan, University of Regensburg and University of Marburg.

Researchers pioneer a revolutionary new method to directly observe dark excitons

Heralding the end of a decade-long quest, in a promising new class of extremely thin, two-dimensional semiconductors, scientists have for the first time directly visualized and measured elusive particles, called dark excitons, that cannot be seen by light.

Researchers confront optics and data-transfer challenges with 3D-printed lens

Researchers have developed new 3-D-printed microlenses with adjustable refractive indices—a property that gives them highly specialized light-focusing abilities. This advancement is poised to improve imaging, computing and communications by significantly increasing the data-routing capability of computer chips and other optical systems, the researchers said.

Research leads to better modeling of hypersonic flow

Hypersonic flight is conventionally referred to as the ability to fly at speeds significantly faster than the speed of sound and presents an extraordinary set of technical challenges. As an example, when a space capsule re-enters Earth's atmosphere, it reaches hypersonic speeds—more than five times the speed of sound—and generates temperatures over 4,000 degrees Fahrenheit on its exterior surface. Designing a thermal protection system to keep astronauts and cargo safe requires an understanding at the molecular level of the complicated physics going on in the gas that flows around the vehicle.

Physicists succeed in bringing movement of photons and electrons under same laws

Scientists from ITMO, Sheffield University, and the University of Iceland proved that the movement of electrons and photons in two-dimensional materials with hexagonal symmetry, such as graphene, submits to the same laws. Now, the properties of electrons in solids can be modeled with the help of classical optical systems where this task can be solved easier. The article was published in Nature Photonics.

Gaia: Most accurate data ever for nearly two billion stars

Today (3 December), an international team of astronomers announced the most detailed ever catalogue of the stars in a huge swathe of our Milky Way galaxy. The measurements of stellar positions, movement, brightness and colours are in the third early data release from the European Space Agency's Gaia space observatory, now publicly available. Initial findings include the first optical measurement of the acceleration of the Solar system. The data set, and early scientific discoveries, were presented at a special briefing hosted by the Royal Astronomical Society.

A three-dimensional view of the Milky Way

In our Milky Way, there are about 200 billion suns as well as large quantities of gas, some of which serves as raw material for star births. The gas collects in compact lumps but also appears as extended molecular clouds. Astronomers have used the Apex sub-millimeter telescope in Chile to look deep into the galactic plane and measure the interstellar medium. They studied the distribution of the cold molecular gas in the inner region of the Milky Way with unprecedented accuracy. The researchers cataloged more than 10,000 interstellar clouds. They found out that currently only about 10% of them contain stars. The project is called SEDIGISM (Structure, Excitation and Dynamics of the Inner Galactic Interstellar Medium) and covers an area of 84 square degrees in the southern sky.

Hubble captures unprecedented fading of Stingray nebula

Great things take time. This is true when it comes to many processes in the universe. For example, it takes millions of years for stars—the building blocks of the universe—to form. Then, many stars last for billions of years before they die and begin to eject shells of gas that glow against the vastness of space—what we call nebulas. It can be exceedingly rare to capture some of these processes in real time.

Now, engineers from the National University of Singapore (NUS) have devised a method to convert natural gas into a non-explosive solid that can be easily stored and transported. Using a novel, low-toxicity additive mixture they formulated, the conversion can be completed in just 15 minutes—the fastest time so far.

Offshore wind industry prepares to ride economic high tide

The U.S. offshore wind energy pipeline is predicted to exceed 25,000 megawatts (MW) by 2030. But, with only two commercial offshore wind plants currently operating in the United States, developers need accurate modeling to evaluate prospective new projects, weigh realistic costs against financial returns, anticipate the impact of technological and process innovations, and quantify risk factors. While technological advancements and improved supply chain efficiencies are helping reduce wind energy costs and generate more energy, offshore wind installations must meet development and operational cost targets to be competitive in the broader energy market.
