Combining classical and quantum computing opens door to new discoveries

Researchers have discovered a new and more efficient computing method for pairing the reliability of a classical computer with the strength of a quantum system.

More than a bumpy ride: Turbulence offers boost to birds

Most sensible air travelers dread turbulence. A little atmospheric hiccup can shake airplanes, rattle nerves and spill beverages. A Cornell University-led study found that birds don't mind at all.

Bending light for safer driving; invisibility cloaks to come?

Optical cloaking allows objects to be hidden in plain sight or to become invisible by guiding light around anything placed inside the cloak. While cloaking has been popularized in fiction, like in the "Harry Potter" books, researchers in recent years have started realizing cloaks that shield objects from view by controlling the flow of electromagnetic radiation around them.

Fuel flow, heat fluctuations drive dangerous oscillations in rocket engines

Researchers 3D-print rotating microfilter for lab-on-a-chip applications

Researchers have fabricated a magnetically driven rotary microfilter that can be used to filter particles inside a microfluidic device. They made the tiny turning filter by creating a magnetic material that could be used with a very precise 3D printing technique known as two-photon polymerization.

The electron merry-go-round: Researchers find new mechanism for classical behavior of many-particle quantum systems

Photoemission is a property of metals and other materials that emit electrons when struck by light. Electron emission after light absorption was already explained by Albert Einstein. But since this effect is a highly complex process, scientists have still not been able to fully elucidate its details. Prof. Dr. Bernd von Issendorff and his team at the University of Freiburg's Institute of Physics have now succeeded in detecting a previously unknown quantum effect in the angular distributions of photoelectrons from cryogenic mass-selected metal clusters. The angular distributions resemble those of classical particles, a behavior that is surprisingly explainable by the strong electron-electron interaction in these many-electron systems. The researchers published this finding in the current issue of Physical Review Letters.

Sticky baseballs: The physics of the latest scandal in Major League Baseball

Cheating in baseball is as old as the game itself, and pitchers' modifying the ball's surface is part of that long history. Adding to the lore of cheating is a new scandal involving pitchers who may be applying sticky substances—what players refer to as "sticky stuff"—to baseballs.

Novel calibration procedure for super-resolution brain imaging

Light—and all waves—can bend around the corners of obstacles found along its path. Because of this phenomenon, called diffraction, it is impossible to focus light onto a spot that is smaller than half its wavelength. In other words, the highest resolution one can theoretically achieve using an optical microscope is approximately 250nm, a barrier called the diffraction limit. Unfortunately, this resolution is not enough for observing fine cellular structures, such as those found in neurons.

World's most powerful magnet ready to ship

Astronomy and Space news

Observations detect a brown dwarf orbiting the star TOI–1278

An international team of astronomers reports the discovery of a companion to the M dwarf star known as TOI–1278. The newly found object turns out to be a brown dwarf nearly 20 times as massive as Jupiter. The finding is detailed in a paper published June 8 on the arXiv pre-print server.

Largest structures in the universe show clear light-shifted signal of rotation

By mapping the motion of galaxies in huge filaments that connect the cosmic web, astronomers at the Leibniz Institute for Astrophysics Potsdam (AIP), in collaboration with scientists in China and Estonia, have found that these long tendrils of galaxies spin on the scale of hundreds of millions of light years. A rotation on such enormous scales has never been seen before. The results published in Nature Astronomy signify that angular momentum can be generated on unprecedented scales.

Coronal mass ejections and cosmic ray observations at Syowa Station

Solar activities, such as CME(Coronal Mass Ejection), cause geomagnetic storms that disturb the Earth's magnetosphere. Geomagnetic storms can affect GPS positioning, radio communication, and power transmission system. Solar explosions also emit radiation, which can cause satellite failures, radiation exposure to aircraft crew, and space activity. Therefore, it is important to understand space weather phenomena and their impact on the Earth.

WaveGlove: A glove with five inertial sensors for hand gesture recognition

Over the past few decades, computer scientists have developed a wide array of models and approaches to analyze different aspects of human behavior and communication, such as speech, emotions and gestures. Most existing techniques for hand gesture recognition rely on the use of wearable technologies with a single sensor and can only recognize a limited number of basic gestures.

Smart fabrics and self-powered sensing

Smart fabrics and wearable electronics can be developed using highly conductive and stretchy fibers. Most of these fiber conductors are, however, strain sensitive with limited conductance on stretching. As a result, a new strategy can be introduced by rearranging the geometry of the conductive path for stable conductance. In a new report now published on Science Advances, Lijing Zheng and colleagues in China and Germany, described a coaxial wet-spinning process to continuously develop intrinsically stretchable and highly conductive, yet conductance-stable liquid metal (LM) sheath-core microfibers. The team stretched the microfibres up to 1170 percent and fully activated the conductive path to obtain a very high conductivity of 4.35 x 104 S/m and a resistance change of only 4 percent at 200 percent strain. The microfiber could be woven easily into everyday glove fabrics and as excellent joule heaters, electro-thermochromic displays and self-powered wearable sensors.

Highly maneuverable miniature robots controlled by magnetic fields
