Spotlight Stories Headlines
? TECHNOLOGY NEWS???:
ENGINEERS DEVELOP POLYMER CORES THAT REDIRECT LIGHT FROM ANY SOURCE TO SOLAR CELLS
Rice University engineers have suggested a colorful solution to next-generation energy collection: Luminescent solar concentrators (LSCs) in your windows.
NREL HEATS UP THERMAL ENERGY STORAGE WITH NEW SOLUTION MEANT TO EASE GRID STRESS, ULTIMATELY IMPROVING ENERGY EFFICIENCY
Scientists from the National Renewable Energy Laboratory (NREL) have developed a simple way to better evaluate the potential of novel materials to store or release heat on demand in your home, office, or other building in a way that more efficiently manages the building’s energy use.
A NEW LEAD-BASED ANODE FOR NEXT-GENERATION LITHIUM-ION BATTERIES
The lithium-ion battery powers everything from mobile phones to laptops to electric vehicles. Scientists worldwide are always on the hunt for new and improved components to build better batteries for these and other applications.
? PHYSICS NEWS⚙♨:
EXPERIMENTAL DEMONSTRATION OF MEASUREMENT-DEPENDENT REALITIES POSSIBLE, RESEARCHER SAYS
Shoe shops sell a variety of shoe sizes to accommodate a variety of foot sizes—but what if both the shoe and foot size depended on how it was measured? Recent developments in quantum theory suggest that the available values of a physical quantity, such as a foot size, can depend on the type of measurement used to determine them. If feet were governed by the laws of quantum mechanics, foot size would depend on the markings on a foot measure to find the best fit—at the time of measurement—and even if the markings were changed, the measurement could still be precise.
HOW ICEBERGS REALLY MELT—AND WHAT THIS COULD MEAN FOR CLIMATE CHANGE
Icebergs are melting faster than current models describe, according to a new study by mathematicians at the University of Sydney. The researchers have proposed a new model to more accurately represent the melt speed of icebergs into oceans.
INTERNATIONAL STUDY REVEALS EXCEPTIONAL PROPERTY OF NEXT GENERATION OPTICAL FIBRES
Researchers from the University of Southampton and Université Laval, Canada, have successfully measured for the first time back reflection in cutting-edge hollow-core fibres that is around 10,000 times lower than conventional optical fibres.
? EARTH NEWS?:
GROUNDWATER RECHARGE RATES MAPPED FOR AFRICA
Effective governance and investment decisions need to be informed by reliable data, not only about where groundwater exists, but also the rate at which groundwater is replenished. For the first time using ground measurements, a recent study has quantified groundwater recharge rates across the whole of Africa—averaged over a fifty-year period—which will help to identify the sustainability of water resources for African nations.
ASTROPHYSICISTS RE-IMAGINE WORLD MAP, DESIGNING A LESS DISTORTED, ‘RADICALLY DIFFERENT’ WAY TO SEE THE WORLD
How do you flatten a sphere?
SPACECRAFT REVEAL NEW DETAILS OF MAGNETIC RECONNECTION
The space environment around Earth is characterized by interactions between Earth’s magnetic field and nearby plasma. A key physical process in these interactions is magnetic reconnection, in which two adjacent field lines break and each half subsequently joins half of the other broken line to form new field lines. Reconnection releases potential energy stored in the field lines, transferring it to the surrounding plasma in the form of particle acceleration.
? ASTRONOMY & SPACE NEWS??:
ASASSN-18aan IS AN UNUSUAL CATACLYSMIC VARIABLE, STUDY FINDS
An international team of astronomers has performed photometric and spectroscopic observations of a binary star system known as ASASSN-18aan and have found that the object is an unusual cataclysmic variable with a relatively long orbital period. The findings were presented February 9 on the arXiv pre-print server.
BIOTECH FIT FOR THE RED PLANET: NEW METHOD FOR GROWING CYANOBACTERIA UNDER MARS-LIKE CONDITIONS
NASA, in collaboration with other leading space agencies, aims to send its first human missions to Mars in the early 2030s, while companies like SpaceX may do so even earlier. Astronauts on Mars will need oxygen, water, food, and other consumables. These will need to be sourced from Mars, because importing them from Earth would be impractical in the long term. In Frontiers in Microbiology, scientists show for the first time that Anabaena cyanobacteria can be grown with only local gases, water, and other nutrients and at low pressure. This makes it much easier to develop sustainable biological life support systems.
PERSEVERANCE ROVER LANDS ON MARS THIS WEEK
After a seven-month journey, NASA’s Perseverance rover prepares to touch down on Mars on Thursday after first negotiating a risky landing procedure that will mark the start of its multi-year search for signs of ancient microbial life.
? NANOTECHNOLOGY NEWS⛄☃:
GRAPHENE ‘NANO-ORIGAMI’ CREATES TINIEST MICROCHIPS YET
The tiniest microchips yet can be made from graphene and other 2-D-materials, using a form of “nano-origami,” physicists at the University of Sussex have found.
GRAPHENE COULD ONE DAY BE USED TO MAKE QUICK, RELIABLE TESTS FOR VIRUSES LIKE SARS-CoV-2
Graphene is a layer of carbon only one atom thick. Since it was first isolated in 2004, it has found applications in strengthening materials, accelerating electronics, and boosting performance in batteries, among others.
TINY LIGHT-EMITTING PROBES GIVE RESEARCHERS A BETTER OPTION FOR NONINVASIVE IMAGING OF LIVING TISSUE
A polymer that is custom designed to produce light that penetrates murky environments has shown promise in bioimaging trials, where it can detect nano-sized particles underneath the surface of realistic tissue models.
