Using historical radar data to map changes in urban environments
Synthetic aperture radar (SAR) is a type of remote sensing from satellites that uses the reflection of radio waves to relay information about the surface of the earth. This reflection, or backscatter, is responsive to physical properties, such as rou.....»»
Most existing heat wave indices fail to capture heat wave severity, experts report
Even though climate change is bringing more frequent and severe heat waves, there is no standard, global way to measure heat-wave severity, and existing indices have different thresholds for defining dangerous heat-stress conditions......»»
The Higgs particle could have ended the universe by now—here"s why we"re still here
Although our universe may seem stable, having existed for a whopping 13.7 billion years, several experiments suggest that it is at risk—walking on the edge of a very dangerous cliff. And it's all down to the instability of a single fundamental part.....»»
Save our waves: Surfing pumps $2.71 billion into the Australian economy and boosts well-being
Ever since Polynesian pioneers took to the ocean on wooden rafts, people have been hooked on riding waves. Today, surfing is one of the world's fastest-growing sports and one of the latest additions to the Olympic games......»»
Prioritize well-being over growth: New paradigm needed for climate-friendly lifestyles
Ensuring the well-being of citizens while reducing resource consumption has proved to be a massive challenge. Policymakers in the European Union are keen to identify new approaches to provisioning that will safeguard the well-being of citizens withou.....»»
Japan sees hottest July since records began
Japan sweltered through its hottest July since records began 126 years ago, the weather agency said, as extreme heat waves fueled by climate change engulfed many parts of the globe......»»
Live service isn’t gaming’s holy grail — and Bungie just proved why
Bungie's latest round of layoffs is yet another sign that live-service games may not be the golden ticket that game studios are desperate for......»»
"Squishy" lasers could reveal how tumors and babies grow
New "squishy" lasers could help solve the mystery of the biological forces that control the development of embryos and cancerous tumors......»»
Can quantum particles mimic gravitational waves?
When two black holes collide, space and time shake and energy spreads out like ripples in a pond. These gravitational waves, predicted by Einstein in 1916, were observed for the first time by the Laser Interferometer Gravitational-Wave Observatory (L.....»»
Extreme heat in India: A crisis on the rise
As global temperatures continue to rise, India is grappling with increasingly severe heat waves. As early as April, many Indian cities, including New Delhi, the capital, have experienced record temperatures above 115 degrees Fahrenheit......»»
Researchers think AI and lasers might help us talk to aliens
Humanity has been searching for extraterrestrial life for decades and trying to communicate with potentially advanced civilizations beyond the stars. So far, the SETI (search … The post Researchers think AI and lasers might help us talk to alie.....»»
The climate is changing so fast, we haven"t seen how bad extreme weather could get
Extreme weather is by definition rare on our planet. Ferocious storms, searing heat waves and biting cold snaps illustrate what the climate is capable of at its worst. However, since Earth's climate is rapidly warming, predominantly due to fossil fue.....»»
Quantum information theorists shed light on entanglement, one of the spooky mysteries of quantum mechanics
The year 2025 marks the 100th anniversary of the birth of quantum mechanics. In the century since the field's inception, scientists and engineers have used quantum mechanics to create technologies such as lasers, MRI scanners and computer chips......»»
Giant waves, monster winds and Earth"s strongest current: Why the Southern Ocean is a global engine room
The Southern Ocean is wild and dynamic. It experiences Earth's strongest winds and largest waves. It is home to city-sized icebergs and the biggest ocean current on the globe, as well as tiny turbulent flows that fit inside a teacup......»»
The New Gods of Weather Can Make Rain on Demand—or So They Want You to Believe
In a gold-trimmed command center on the outskirts of Abu Dhabi, scientists are seeking to wring moisture from desert skies. But will all their extravagant cloud-seeding tech—planes that sprinkle nanomaterials, lasers that scramble the atmosphere—.....»»
Why the solar corona is so much hotter than sun"s surface
In a new study published in The Astrophysical Journal, a researcher from The University of Alabama in Huntsville (UAH), a part of the University of Alabama System, explores critical aspects of a phenomenon called kinetic Alfvén waves (KAWs) to provi.....»»
New study simulates gravitational waves from failing warp drive
Imagine a spaceship driven not by engines, but by compressing the spacetime in front of it. That's the realm of science fiction, right? Well, not entirely. Physicists have been exploring the theoretical possibility of "warp drives" for decades, and a.....»»
Apple patents way to replace car mirrors with cameras, with windshield projection
The Apple Car project may be dead, but there’s still a chance we’ll see some Apple tech in cars made by other companies – and a patent application for a way to replace car mirrors with cameras could be an interesting candidate. Such systems.....»»
Fossil algae show a lake once existed on Lesotho"s Mafadi summit, but it vanished about 150 years ago
Lesotho is a small, land-locked, mountainous country located in the middle of South Africa. Its Eastern Lesotho Highlands are often referred to as the region's "water tower" because they receive some of the highest rainfall amounts in southern Africa.....»»
3D models show dolphins already used narrow-band sound waves for orientation 5 million years ago
Senckenberg researcher Dr. Rachel Racicot and her former student Joyce Sanks from Vanderbilt University have examined the inner ear of the extinct dolphin genus Parapontoporia. In their study, published in the journal The Anatomical Record, they show.....»»
