WSR: A NEW WI-FI-BASED SYSTEM FOR COLLABORATIVE ROBOTICS
Researchers at Harvard University have recently devised a system based on Wi-Fi sensing that could enhance the collaboration between robots operating in unmapped environments. This system, presented in a paper pre-published on arXiv, can essentially emulate antenna arrays in the air as a robot moves freely in a 2-D or 3-D environment.
A STRATEGY TO IMPROVE THE EFFICIENCY AND LONG-TERM STABILITY OF PEROVSKITE SOLAR CELLS
Over the past few years, researchers have been trying to develop new designs for perovskite solar cells that could improve their performance, efficiency and stability over time. One possible way of achieving this is to combine 2-D and 3-D halide perovskites in order to leverage the advantageous properties of these two different types of perovskites.
HOW SHORT CIRCUITS IN LITHIUM METAL BATTERIES CAN BE PREVENTED
There are high hopes for the next generation of high energy-density lithium metal batteries, but before they can be used in our vehicles, there are crucial problems to solve. An international research team led by Chalmers University of Technology, Sweden, has now developed concrete guidelines for how the batteries should be charged and operated, maximizing efficiency while minimizing the risk of short circuits.

A REALISTIC MODEL OF THE ITER TOKAMAK MAGNETIC FUSION DEVICE
Tokamaks, devices that use magnetic fields to confine plasma into torus-shaped chamber, could play a crucial role in the development of highly performing nuclear fusion reactors. The ITER tokamak, which is set to be the largest nuclear tokamak in the world, is particularly likely to shape the way in which nuclear reactors will be fabricated in the future.
LIGHT-CONTROLLED HIGGS MODES FOUND IN SUPERCONDUCTORS; POTENTIAL SENSOR, COMPUTING USES
Even if you weren’t a physics major, you’ve probably heard something about the Higgs boson.
EGGS REVEAL WHAT MAY HAPPEN TO BRAIN ON IMPACT
What causes brain concussions? Is it direct translational or rotational impact? This is one of the research areas currently being explored by Qianhong Wu’s lab at Villanova University.
? EARTH NEWS?:
GOING WITH THE GRAINS TO EXPLAIN A FUNDAMENTAL TECTONIC FORCE
A new study suggests that tiny, mineral grains—squeezed and mixed over millions of years—set in motion the chain of events that plunge massive tectonic plates deep into the Earth’s interior.
USING 100-MILLION-YEAR-OLD FOSSILS AND GRAVITATIONAL-WAVE SCIENCE TO PREDICT EARTH’S FUTURE CLIMATE
A group of international scientists, including an Australian astrophysicist, has used findings from gravitational wave astronomy (used to find black holes in space) to study ancient marine fossils as a predictor of climate change.
ABANDONED CROPLAND SHOULD PRODUCE BIOFUELS
Growing perennial grasses on abandoned cropland has the potential to counteract some of the negative impacts of climate change by switching to more biofuels, according to an NTNU research group.

NASA EXPLORES SOLAR WIND WITH NEW VIEW OF SMALL SUN STRUCTURES
Scientists have combined NASA data and cutting-edge image processing to gain new insight into the solar structures that create the Sun’s flow of high-speed solar wind, detailed in new research published today in The Astrophysical Journal. This first look at relatively small features, dubbed “plumelets,” could help scientists understand how and why disturbances form in the solar wind.
THE MILKY WAY DOES THE WAVE
In results announced this week at the 237th Meeting of the American Astronomical Society, scientists from the Sloan Digital Sky survey present the most detailed look yet at the warp of our own galaxy.
MYSTERY OF MARTIAN GLACIERS REVEALED
In a new paper published today in the Proceedings of the National Academies of ScienceS (PNAS), planetary geologist Joe Levy, assistant professor of geology at Colgate University, reveals a groundbreaking new analysis of the mysterious glaciers of Mars.

MULTIDIMENSIONAL COHERENT SPECTROSCOPY REVEALS TRIPLET STATE COHERENCES IN CESIUM LEAD-HALIDE PEROVSKITE NANOCRYSTALS
Advanced optoelectronics require materials with newly engineered characteristics. Examples include a class of materials named metal-halide perovskites that have tremendous significance to form perovskite solar cells with photovoltaic efficiencies. Recent advances have also applied perovskite nanocrystals in light-emitting devices. The unusually efficient light emission of cesium lead-halide perovskite may be due to a unique excitonic fine structure made of three bright triplet states that minimally interact with a proximal dark singlet state. Excitons are electronic excitations responsible for the emissive properties of nanostructured semiconductors, where the lowest-energy excitonic state is expected to be long lived and hence poorly emitting (or ‘dark’).
DNA ORIGAMI ENABLES FABRICATING SUPERCONDUCTING NANOWIRES
The quest for ever-smaller electronic components led an international group of researchers to explore using molecular building blocks to create them. DNA is able to self-assemble into arbitrary structures, but the challenge with using these structures for nanoelectronic circuits is the DNA strands must be converted into highly conductive wires.
