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.....»»
Bizarre ancient sea creature brings evolution mystery to the surface
A new tunicate fossil, a close relative of vertebrates, is half a billion years old. Enlarge / That blue tube is actually a very close relative of vertebrates. (credit: Gerard Soury) Beneath the waves, there are strange,.....»»
Astronomers observe subpulse drifting and nulling of pulsar PSR J0026–1955
Using the upgraded Giant Meterwave Radio Telescope (uGMRT), astronomers from India and Australia have performed radio observations of a pulsar known as PSR J0026–1955. Results of the observational campaign, published July 5 on the preprint server a.....»»
Light-based “LiFi” is stunningly fast, notably fragile—and now standardized
224GB/s, killer security, no radio interference—but you can't block the beam. Enlarge / "I can't believe the quality of this 8K video tutorial! It's like you're really… Ted, could you, yeah, just shift over a little there? Yo.....»»
Astronomers identify the coldest star yet that emits radio waves
Astronomers at the University of Sydney have shown that a small, faint star is the coldest on record to produce emission at radio wavelength......»»
Tidal capture of an asteroid by a magnetar
Recently astronomers have been able to associate two seemingly unrelated phenomena: an explosive event known as a fast radio burst and the change in speed of a spinning magnetar. And now new research suggests that the cause of both of these is the de.....»»
Research reveals processes that sculpt submarine canyons
Deep below Monterey Bay lies one of the largest submarine canyons on the west coast of North America. Monterey Canyon has a topography that rivals the Grand Canyon, but its scale and grandeur remain out of sight beneath the waves. Repeated efforts at.....»»
Biologists identify mechanical waves involved in limb regeneration in zebrafish
A team of molecular and cellular biologists from several institutions in Taiwan and one in the Philippines has identified some of the mechanical waves involved in the regeneration of amputated tailfins in zebrafish. In their study, reported in the jo.....»»
Researchers want to use gravitational waves to learn about dark matter
A team of astronomers has come up with a method for using gravitational waves to study the mysterious phenomenon of dark matter......»»

Pok Pok Playroom iOS app for kids launches creative ‘World Puzzle’ toy
Following great updates this year that brought the new Radio and Islands toys, the award-winning Pok Pok Playroom for kids has received its latest update. The new release introduces the “World Puzzle” toy that encourages growth with creativity,.....»»
Using gravitational waves to hunt for dark matter
Using computer simulations, an international team of cosmologists have discovered that observations of gravitational waves from merging black holes may unveil the true nature of dark matter. Their finding will be presented today at the 2023 National.....»»
Warming waters spark "evolution at super speed" in marine sponges, study finds
Marine heat waves caused by the warming climate are capable of sparking rapid changes in sea sponges with scientists describing the pace of change as "evolution at super speed.".....»»
New radio observations confirm unintended electromagnetic radiation emanating from large satellite constellations
Scientists from a number of leading research institutions including the Max Planck Institute for Radio Astronomy in Bonn, Germany, used the Low Frequency Array (LOFAR) telescope to observe 68 of SpaceX's satellites. The authors conclude that they det.....»»
Astronomers use dead stars to measure gravitational waves produced by ancient black holes
An international team of astronomers has detected a faint signal of gravitational waves reverberating through the universe. By using dead stars as a giant network of gravitational wave detectors, the collaboration—called NANOGrav—was able to meas.....»»
Physicists rediscover a discarded theory to solve a mystery of how glass damping sound
For about half a century, physicists have puzzled over vibrations in glass at low temperatures. The reason: Glass carries sound waves and vibrations differently than other solids—it "vibrates differently." But why? And how can the propagation of so.....»»
Novel microwave isolator points the way to new radio cameras and quantum computers
Researchers at the National Astronomical Observatory of Japan (NAOJ) have invented a novel microwave isolator and have demonstrated, for the first time, its basic principle that enables small isolators; essential for future quantum computers. This is.....»»
Scientists have finally "heard" the chorus of gravitational waves that ripple through the universe
Scientists have observed for the first time the faint ripples caused by the motion of black holes that are gently stretching and squeezing everything in the universe......»»
Using a detector the size of a galaxy, astronomers detect gravitational waves from supermassive black hole pairs
When black holes and other enormously massive, dense objects whirl around one another, they send out ripples in space and time called gravitational waves. These waves are one of the few ways we have to study the enigmatic cosmic giants that create th.....»»
NASA"s Mars helicopter "phones home" after no contact for 63 days
Long time, no speak: NASA has re-established contact with the intrepid Ingenuity Mars Helicopter after more than two months of radio silence, the space agency said Friday......»»
Astrophysicists propose a new way of measuring cosmic expansion: lensed gravitational waves
The universe is expanding; we've had evidence of that for about a century. But just how quickly celestial objects are receding from each other is still up for debate......»»
