Through Hurricanes Helene and Milton, Amateur Radio Triumphs When All Else Fails
While some residents in hurricane-impacted areas can't send texts or make calls, amateur radio enthusiasts are helping communicate requests for help and messages between loved ones......»»
Broadcast police communications may pose privacy risks, especially to Black men
Police radio transmissions contain personally identifiable information that could pose privacy risks for members of the public, especially Black males, according to a new study by researchers at Penn State and the University of Chicago......»»
Are fast radio bursts caused by interstellar objects crashing into neutron stars?
Every now and then, astronomers will detect an odd kind of radio signal. So powerful it can outshine a galaxy, but lasting only milliseconds. They are known as fast radio bursts (FRBs). When they were first discovered a couple of decades ago, we had.....»»
Climate change goosed hurricane wind strength by 18 mph since 2019, study says
Human-caused climate change made Atlantic hurricanes about 18 miles per hour (29 kilometers per hour) stronger in the last six years, a new scientific study found Wednesday......»»

Improving hurricane modeling with physics-informed machine learning
Hurricanes, or tropical cyclones, can be devastating natural disasters, leveling entire cities and claiming hundreds or thousands of lives. A key aspect of their destructive potential is their unpredictability. Hurricanes are complex weather phenomen.....»»
New giant radio galaxy discovered with MeerKAT
An international team of astronomers has employed the MeerKAT radio telescope to investigate giant radio galaxies in the field of the Cosmological Evolution Survey (COSMOS). They found a new giant radio galaxy that had not been reported before. The f.....»»
The Arecibo Message, Earth’s First Interstellar Transmission, Turns 50
In 1974 we beamed a radio transmission into space that changed the way we think about our place in the cosmos.....»»
Apple pulls US-funded Radio Free Europe app from Russia
The Radio Free Europe/Radio Liberty news app has been removed from the App Store in Russia, in another case of the state mandating what apps are allowed.The App Store is a powerful digital ecosystem.The move comes less than a month after the Russian.....»»
Three innovative ways to help countries hit by climate disasters, beyond a loss and damage fund
These days, it's hard to escape news stories discussing how climate change is contributing to extreme weather disasters, including the recent U.S. hurricanes. Aid agencies are increasingly worried about the widespread damage......»»
Climate scientist combines research and teaching into "perfect storm" of discovery
This fall, Hurricanes Helene and Milton served as painful reminders of how climate change is fueling extreme weather, supplying warmer ocean waters and warmer air temperatures that lead to wetter, stronger tropical cyclones......»»
Autumn leaves are staying green for longer in Britain. Here"s why
Every year people ask me, "why haven't the leaves fallen yet?" If autumn starts on September 1, then by early November winter should be well on its way. And yet, an amateur photographer who has captured the season's colors for several years in southe.....»»
3D leaf edge reconstruction method enhances plant morphology analysis
Leaves, essential for photosynthesis and other physiological functions, exhibit diverse shapes that help plants adapt to their environments. Traditional methods for measuring leaf morphology have relied heavily on 2D imaging, which fails to capture t.....»»
HomeKit Weekly: Track your HomeKit device batteries with HomeBatteries
Keeping tabs on battery-powered HomeKit accessories like the can be challenging. From smart locks to motion sensors, battery status is often out of sight, out of mind—until the moment a device fails to respond. Enter HomeBatteries, an app designed.....»»
How to build a home radio telescope to detect clouds of hydrogen in the Milky Way
If I ask you to picture a radio telescope, you probably imagine a large dish pointing to the sky, or even an array of dish antennas such as the Very Large Array. What you likely don't imagine is something that resembles a TV dish in your neighbor's b.....»»
Pathogens that cling to microplastics may survive wastewater treatment
Wastewater treatment fails to kill several human pathogens when they hide out on microplastics in the water, reports a study led by Ingun Lund Witsø of the Norwegian University of Life Sciences, published November 6, 2024 in the open-access journal.....»»
New report details what happened to the Arecibo Observatory
In 1963, the Arecibo Observatory became operational on the island of Puerto Rico. Measuring 305 meters (~1000 ft) in diameter, Arecibo's spherical reflector dish was the largest radio telescope in the world at the time—a record it maintained until.....»»
Mighty radio bursts linked to massive galaxies: New clues about how magnetars form
Since their discovery in 2007, fast radio bursts—extremely energetic pulses of radio-frequency light—have lit up the sky repeatedly, leading astronomers on a chase to uncover their origins. Currently, confirmed fast radio bursts, or FRBs, number.....»»
Successful demonstration of a commercial cryogenic radio frequency power sensor paves way for quantum computing
Radio frequency (RF) and microwave power measurements are widely used to support applications across space, defense, and communication. These precise measurements enable engineers to accurately characterize waveforms, components, circuits, and system.....»»
