Spotlight Stories Headlines
🗞 TECHNOLOGY NEWS💻🔧🖥:
A ROBOT THAT CAN TRACK SPECIFIC PEOPLE AND FOLLOW THEM AROUND
Telling humans apart and following them as they move in their surrounding environment could be two highly valuable skills for service robots. In fact, when combined, these two capabilities would allow robots to follow specific people as they are interacting with them or offering their assistance.
SOLAR DEVICE CAN STERILIZE MEDICAL TOOLS IN OFF-GRID AREAS WITHOUT THE NEED FOR ELECTRICITY
Autoclaves, the devices used to sterilize medical tools in hospitals, clinics, and doctors’ and dentists’ offices, require a steady supply of pressurized steam at a temperature of about 125 degrees Celsius. This is usually provided by electrical or fuel-powered boilers, but in many rural areas, especially in the developing world, power can be unreliable or unavailable, and fuel is expensive.
CURVED ORIGAMI PROVIDES NEW RANGE OF STIFFNESS-TO-FLEXIBILITY IN ROBOTS
New research that employs curved origami structures has dramatic implications in the development of robotics going forward, providing tunable flexibility—the ability to adjust stiffness based on function—that historically has been difficult to achieve using simple design.
🗞 PHYSICS NEWS⚙♨:
OIL DROPLET PREDATORS CHASE OIL DROPLET PREY
Oil droplets can be made to act like predators, chasing down other droplets that flee like prey. The behavior, which is controlled by chemical signaling produced by the droplets, mimics behavior seen among living organisms but, until now, had not been recreated in synthetic systems. This tunable chemical system could potentially serve a model to help understand interactions in many-body systems such as schools of fish, bacterial colonies, or swarms of insects.
FASTER MAGNETIC SWITCH WITH LOWER ENERGY CONSUMPTION DEVELOPED
Magnetic materials are ubiquitous in modern society, present in nearly all the technological devices we use every day. In particular, personal electronics like smartphones/watches, tablets, and desktop computers all rely on magnetic material to store information. Information in modern devices is stored in long chains of 1’s and 0’s, in the binary number system used as the language of computers.
RESEARCHERS ESTABLISH PROOF OF PRINCIPLE IN SUPERCONDUCTOR STUDY
Three physicists in the Department of Physics and Astronomy at the University of Tennessee, Knoxville, together with their colleagues from the Southern University of Science and Technology and Sun Yat-sen University in China, have successfully modified a semiconductor to create a superconductor.
🗞 EARTH NEWS🌏:
FARMS, TABLES AND VAST IMPACTS BETWEEN AND BEYOND
Bountiful harvests in one location can mean empty water reservoirs and environmental woes far from farmlands. A unique study in this week’s Nature Communications examines how food, energy, water and greenhouse gases create a vast front in the battle to feed the planet.
PIECING TOGETHER THE ALASKA COASTLINE’S FRACTURED VOLCANIC ACTIVITY
Among seismologists, the geology of Alaska’s earthquake- and volcano-rich coast from the Aleutian Islands to the southeast is fascinating, but not well understood. Now, with more sophisticated tools than before, a University of Massachusetts Amherst team reports unexpected new details about the area’s tectonic plates and their relationships to volcanoes.
GEOSCIENTISTS DISCOVER ANCESTRAL PUEBLOANS SURVIVED FROM ICE MELT IN NEW MEXICO LAVA TUBES
For more than 10,000 years, the people who lived on the arid landscape of modern-day western New Mexico were renowned for their complex societies, unique architecture and early economic and political systems. But surviving in what Spanish explorers would later name El Malpais, or the “bad lands,” required ingenuity now being explained for the first time by an international geosciences team led by the University of South Florida.
🗞 ASTRONOMY & SPACE NEWS🌪🎇:
IN THE MYSTERIOUS BLUE RING NEBULA, SCIENTISTS SEE THE FATE OF BINARY STARS
Scientists have discovered a rare object called the Blue Ring Nebula, a ring of hydrogen gas with a star at its center. The properties of this system suggest it is the remnant of two stars meeting their ultimate demise: an inward orbital dance that resulted in the two stars merging. The result offers a new window into the fate of many tightly orbiting binary star systems.
WILL SMALL ROCKETS FINALLY LIFT OFF?
The boom in demand for placing small satellites into orbit has boosted interest in small rockets, but industry players do not think the niche will become a business segment of its own.
TEN TIMES MORE HYPER-LUMINOUS GALAXIES OBSERVED THAN STARS CAN PRODUCE
A team of astronomers led by SRON Netherlands Institute for Space Research has observed 10 times more hyper-luminous galaxies in the infrared than stars can produce according to the models. If the theory is correct, it means that stars alone cannot account for the brightness of the most luminous infrared galaxies. The paper was published in a special issue of Astronomy & Astrophysics.
🗞 NANOTECHNOLOGY NEWS⛄☃:
A TECHNIQUE TO OVER-DOPE GRAPHENE BEYOND THE VAN HOVE SINGULARITY
For over a decade, theoretical physicists have predicted that the van Hove singularity of graphene could be associated with different exotic phases of matter, the most notable of which is chiral superconductivity.
TINY TUBES COME IN BIG PACKAGES
Membrane-based systems have great potential as low energy alternatives in applications like desalination, pharmaceutical recovery, purification and waste treatment.
SCIENTISTS MAKE INSTA-BLING AT ROOM TEMPERATURE
An international team of scientists has defied nature to make diamonds in minutes in a laboratory at room temperature—a process that normally requires billions of years, huge amounts of pressure and super-hot temperatures.
