Seeing with radio waves
Scientists from the Division of Physics at the University of Tsukuba used the quantum effect called 'spin-locking' to significantly enhance the resolution when performing radio-frequency imaging of nitrogen-vacancy defects in diamond. This work may l.....»»
Researchers reveal parsec-scale radio emission properties of dual AGNs by multi-phase-center VLBI observations
Galaxy mergers play a crucial role in the cosmological evolution of galaxies. During galaxy merging, tidal torques can trigger the accretion and feedback of the central black holes in merging galaxies, forming dual active galactic nuclei (AGNs)......»»
How astronomers are using pulsars to observe evidence of dark matter
Tantalizing evidence of potential dark matter objects has been detected with the help of the universe's "timekeepers." These pulsars—neutron stars which rotate and emit lighthouse-like beams of radio waves that rapidly sweep through space—were us.....»»
Amid a sweltering summer, a new study finds street trees thrive in NYC
So far this summer, New York City—like much of the country—has clocked more than 11 90-plus degree days. In addition to the increasing frequency of extreme heat waves, if it seems hotter in the city than in other environments, it typically is......»»
Q&A: Researcher discusses how gravitational waves hint at dark matter and Big Bang mysteries
Gravitational waves, ripples in space-time predicted by Einstein almost a century ago, were detected for the first time in 2015. A new study led by Yanou Cui, an associate professor of physics and astronomy at the University of California, Riverside,.....»»
Researchers demonstrate anomalous Brewster effect in metamaterials
The Brewster reflectionless effect stands out as one of the simplest yet pivotal discoveries in manipulating waves. Initial investigations were limited to isotropic materials, but later, thanks to the advent of metamaterials, the phenomenon was found.....»»
Meteorological study provides enhanced understanding of tropical atmospheric waves
In a new meteorological study, an international team of researchers from the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science, the European Centre for Medium-Range Weather Forecasts (ECMWF; Reading, UK), and the Nationa.....»»

How cities can use AI to adapt to climate change
Urban spaces are particularly susceptible to the effects of climate change, such as heat waves, floods, and storms. But which areas of a city are affected, and how can city planners respond?.....»»
Heat Waves Need FEMA’s Help
Heat waves are costly and kill more people each year than hurricanes, tornadoes and floods combined, but because FEMA doesn’t count them as disasters, communities miss out on important resources.....»»
Heat Waves Can Buckle Train Tracks, Delaying Commutes and Commerce
Extreme heat can cause train tracks to expand and buckle. That’s forcing rail operators to adapt as the climate warms.....»»
5 New Types of Gravitational-Wave Detectors Could Reshape Astrophysics
With the confirmation of gravitational waves less than a decade old, scientists are barreling ahead with new detectors to pick up ever more elusive ripples in spacetime.....»»
New Antikythera mechanism analysis challenges century-old assumption
Physicists drew on statistical techniques used to analyze gravitational waves. Enlarge / Fragment of the Antikythera mechanism, circa 205 BC, housed in the collection of the National Archaeological Museum, Athens. (credit: Fine A.....»»
Visualizing the boundary modes of the charge density wave in a topological material
Charge density waves are quantum phenomena occurring in some materials, which involve a static modulation of conduction electrons and the periodic distortion of the lattice. These waves have been observed in numerous condensed matter materials, inclu.....»»
Improved imaging offers new insight into Mount Etna
With a technique called seismic tomography, researchers use the shape of traveling seismic waves from nearby or distant earthquakes to create 3D images of inner Earth, allowing them to "see" hundreds of kilometers below the surface......»»
NASA mission to study mysteries in the origin of solar radio waves
NASA's CubeSat Radio Interferometry Experiment, or CURIE, is scheduled to launch July 9, 2024, to investigate the unresolved origins of radio waves coming from the sun......»»
Exploring the possibility of probing fundamental spacetime symmetries via gravitational wave memory
As predicted by the theory of general relativity, the passage of gravitational waves can leave a measurable change in the relative positions of objects. This physical phenomenon, known as gravitational wave memory, could potentially be leveraged to s.....»»
Repurposed technology used to probe new regions of Mars" atmosphere
Using the repurposed equipment, a team including Imperial College London researchers have measured parts of the Martian atmosphere that were previously impossible to probe. This includes areas that can block radio signals if not properly accounted fo.....»»
India is likely undercounting heat deaths, affecting its response to increasingly harsh heat waves
Months of scorching temperatures sometimes over 50 degrees Celsius (122 Fahrenheit) in parts of India this year—its worst heat wave in over a decade—left hundreds dead or ill. But the official number of deaths listed in government reports barely.....»»

Extreme heat waves highlight climate injustice while western countries fail to act—how governments can help
Average global air temperatures breached 1.5°C for the first time at the start of 2024—at least five years earlier than predicted. So, while developing countries burn, global climate injustice persists......»»
