aA METHOD TO TRACK THE OUTDOOR PERFORMANCE OF PEROVSKITE SOLAR MINIMODULES
In recent years, researchers have been developing a wide range of technologies designed to convert renewable energy sources, such as sunlight and wind, into electrical energy. This includes solar or photovoltaic (PV) cells, devices that can convert light into electrical energy and are typically combined to form solar panels.
RASPBERRY UNVEILS $4 Pi PICO MICROCONTROLLER
Raspberry is introducing a new member to its family: a microcontroller. And its price won’t set anyone back too much: The new Raspberry Pi Pico costs about the same as a box of fresh-picked raspberries at the grocery store, $4.
NEW STUDY REVEALS SECRETS TO SOLAR SUCCESS
A new study shows how researchers at The Australian National University (ANU) achieved a world record in solar cell efficiency.

RECORD-BREAKING LASER LINK COULD PROVIDE TEST OF EINSTEIN’S THEORY
Scientists from the International Centre for Radio Astronomy Research (ICRAR) and the University of Western Australia (UWA) have set a world record for the most stable transmission of a laser signal through the atmosphere.
THE MYSTERY OF POINTY OIL DROPLETS
A certain type of oil droplets changes shape when cooled and shrunk: from spherical through icosahedral to flat hexagonal. Two competing theories couldn’t fully explain this, but now, a Physical Review Letter by Ireth García-Aguilar and Luca Giomi solves the mystery.
USING THE UNPREDICTABLE NATURE OF QUANTUM MECHANICS TO GENERATE TRULY RANDOM NUMBERS
A team of researchers from the U.K., Germany and Russia has used the unpredictable nature of quantum mechanics to create a device capable of generating truly random numbers. In their paper published in the journal Physical Review Letters, the group describes using aspects of quantum theory to develop a framework for building a truly random number generator.

ROLE OF DAMS IN REDUCING GLOBAL FLOOD EXPOSURE UNDER CLIMATE CHANGE
A new collaborative study led by researchers at the National Institute for Environmental Studies, the University of Tokyo, and Michigan State University exposes the role of dams for mitigating flood risk under climate change.
IRRIGATION SCHEMES IN SUB-SAHARAN AFRICA ARE CONSISTENTLY FALLING SHORT OF THEIR PROMISES
Irrigation schemes in sub-Saharan Africa don’t measure up to their plans according to new research into the projects by scientists. Many of the schemes were found to be consistently delivering a much smaller area of irrigation or are completely broken and things aren’t improving.
A NEW WAY TO FORECAST BEACH WATER QUALITY
Less than two days of water quality sampling at local beaches may be all that’s needed to reduce illnesses among millions of beachgoers every year due to contaminated water, according to new Stanford research. The study, published in Environmental Science & Technology, presents a modeling framework that dependably predicts water quality at beaches after only a day or two of frequent water sampling. The approach, tested in California, could be used to keep tabs on otherwise unmonitored coastal areas, which is key to protecting the well-being of beachgoers and thriving ocean economies worldwide.

ASTRONOMERS DISCOVER FIRST CLOUDLESS, JUPITER-LIKE PLANET
Astronomers at the Center for Astrophysics | Harvard & Smithsonian have detected the first Jupiter-like planet without clouds or haze in its observable atmosphere. The findings were published this month in the Astrophysical Journal Letters.
THE SEVEN ROCKY PLANETS OF TRAPPIST-1 SEEM TO HAVE VERY SIMILAR COMPOSITIONS
The red dwarf star TRAPPIST-1 is home to the largest group of roughly Earth-size planets ever found in a single stellar system. Located about 40 light-years away, these seven rocky siblings provide an example of the tremendous variety of planetary systems that likely fill the universe.
MAGNETIC WAVES EXPLAIN MYSTERY OF SUN’S OUTER LAYER
The Sun’s extremely hot outer layer, the corona, has a very different chemical composition from the cooler inner layers, but the reason for this has puzzled scientists for decades.

OBSERVING CHIRAL EDGE STATES IN GAPPED NANOMECHANICAL GRAPHENE
Edge states are an emerging concept in physics and have been explored as an efficient strategy to manipulate electrons, photons and phonons for next-generation hybrid electro-optomechanical circuits. Scientists have used gapless chiral edge states in graphene or graphene-like materials to understand exotic quantum phenomena such as quantum spin or valley Hall effects. In a new report now published on Science Advances, Xiang Xi and colleagues reported on experimental chiral edge states in gapped nanomechanical graphene; a honeycomb lattice of free-standing silicon nitride nanomechanical membranes with broken spatial inversion symmetry (presence of a dipole). The constructs were immune against backscattering in sharp bends and exhibited the valley-momentum locking effect. The team realized a smooth transition between the chiral edge states and the well-known valley kink states to open the door for experimental investigations of soft graphene-related physics in very-high-frequency, integrated nanomechanical systems.
NEW SELF-ASSEMBLY METHOD CREATES BIOELECTRONICS OUT OF MICROSCOPIC STRUCTURES
Bringing together soft, malleable living cells with hard, inflexible electronics can be a difficult task. UChicago researchers have developed a new method to face this challenge by utilizing microscopic structures to build up bioelectronics rather than creating them from the top down—creating a highly customizable product.
SPECIALLY ORIENTED TWISTED BILAYER GRAPHENE HOSTS TOPOLOGICAL ELECTRONIC STATES
A sheet of magic-angle twisted bilayer graphene can host novel topological phases of matter, a study has revealed.
