A SINGLE SPIN-ORBIT TORQUE DEVICE TO SENSE 3D MAGNETIC FIELDS
Sensors that can detect magnetic fields have many potential applications, for instance, in the development of sophisticated medical devices and transportation systems. Most approaches for detecting 3D magnetic fields developed so far, however, require several sensors, which makes them bulky and difficult to implement on a large-scale.
X-ray STUDY RECASTS ROLE OF BATTERY MATERIAL FROM CATHODE TO CATALYST
An international team working at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) used a unique X-ray instrument to learn new things about lithium-rich battery materials that have been the subject of much study for their potential to extend the range of electric vehicles and the operation of electronic devices.
ROBO-STARFISH AIMS TO ENABLE CLOSER STUDY OF AQUATIC LIFE
Biologists have long experienced the challenges of documenting ocean life, with many species of fish proving quite sensitive to the underwater movements of humans.

LEARNING WHAT MAKES THE NUCLEUS TICK
Michigan State University’s Witold Nazarewicz has a simple way to describe the complex work he does at the Facility for Rare Isotope Beams, or FRIB.
HOW WE FOUND HINTS OF NEW PARTICLES OR FORCES OF NATURE – AND WHY IT COULD CHANGE PHYSICS
Seven years ago, a huge magnet was transported over 3,200 miles (5,150km) across land and sea, in the hope of studying a subatomic particle called a muon
? EARTH NEWS?:
EARTH’S CRUST MINERALOGY DRIVES HOTSPOTS FOR INTRATERRESTRIAL LIFE
Below the verdant surface and organic rich soil, life extends kilometers into Earth’s deep rocky crust. The continental deep subsurface is likely one of the largest reservoirs of bacteria and archaea on Earth, many forming biofilms—like a microbial coating of the rock surface. This microbial population survives without light or oxygen and with minimal organic carbon sources, and can get energy by eating or respiring minerals. Distributed throughout the deep subsurface, these biofilms could represent 20-80% of the total bacterial and archaeal biomass in the continental subsurface according to the most recent estimate. But are these microbial populations spread evenly on rock surfaces, or do they prefer to colonize specific minerals in the rocks?
COULD MARIO KART TEACH US HOW TO REDUCE WORLD POVERTY AND IMPROVE SUSTAINABILITY?
Many Mario Kart enthusiasts are familiar with the rush of racing down Rainbow Road, barely squeaking around a corner, and catching a power-up from one of the floating square icons on the screen—or, less ideally, slipping on a banana peel laid by another racer and flying off the side of the road into oblivion. This heated competition between multiple players, who use a variety of game tokens and tools to speed ahead or thwart their competitors, is part of what makes the classic Nintendo racing game that has been around since the early 1990s so appealing.

NEW RESEARCH REVEALS SECRET TO JUPITER’S CURIOUS AURORA ACTIVITY
Auroral displays continue to intrigue scientists, whether the bright lights shine over Earth or over another planet. The lights hold clues to the makeup of a planet’s magnetic field and how that field operates.
LONG-AWAITED REVIEW REVEALS JOURNEY OF WATER FROM INTERSTELLAR CLOUDS TO HABITABLE WORLDS
Dutch astronomer Ewine van Dishoeck (Leiden University, the Netherlands), together with an international team of colleagues, has written an overview of everything we know about water in interstellar clouds thanks to the Herschel space observatory. The article, published in the journal Astronomy & Astrophysics, summarizes existing knowledge and provides new information about the origin of water on new, potentially habitable, worlds. The article is expected to serve as a reference work for the next twenty years.
? NANOTECHNOLOGY NEWS⛄☃:
DISCOVERY COULD LENGTHEN LIFESPAN OF ELECTRONIC DEVICES
Nobel laureate Herbert Kroemer once famously asserted “The interface is the device.” The observations by the Sydney researchers could therefore spark a new debate on whether interfaces—which are physical boundaries separating different regions in materials—are a viable solution to the unreliability of next-generation devices.
OPTICALLY ACTIVE DEFECTS IMPROVE CARBON NANOTUBES
The properties of carbon-based nanomaterials can be altered and engineered through the deliberate introduction of certain structural “imperfections” or defects. The challenge, however, is to control the number and type of these defects. In the case of carbon nanotubes—microscopically small tubular compounds that emit light in the near-infrared—chemists and materials scientists at Heidelberg University led by Prof. Dr. Jana Zaumseil have now demonstrated a new reaction pathway to enable such defect control. It results in specific optically active defects—so-called sp3 defects—which are more luminescent and can emit single photons, that is, particles of light. The efficient emission of near-infrared light is important for applications in telecommunication and biological imaging.
