Study finds sea-level rise and weather-related shocks caused Louisiana marsh to die back
In 2016, observers in the wetlands of Louisiana's Bird's Foot Delta began to note dying stands of Phragmites australis, locally known as Roseau cane. By 2021, nothing but mud flats remained in some areas where the reeds once stood......»»
Researchers develop a detector for continuously monitoring toxic gases
Most systems used to detect toxic gases in industrial or domestic settings can be used only once, or at best a few times. Now, researchers at MIT have developed a detector that could provide continuous monitoring for the presence of these gases, at l.....»»

What does the ‘Air’ in ‘iPad Air’ mean nowadays? Greg Joswiak has an answer
After Apple’s iPad-focused event last week, many observers – including yours truly – pointed out that the new iPad Pro is actually thinner and lighter than the iPad Air. This had me wondering what “Air” actually means nowadays for Apple......»»
Major ChatGPT-4o update allows audio-video talks with an “emotional” AI chatbot

Astronomers are on the hunt for Dyson spheres
There's something poetic about humanity's attempt to detect other civilizations somewhere in the Milky Way's expanse. There's also something futile about it. But we're not going to stop. There's little doubt about that......»»
Rolling with the punches: How mantis shrimp defend against high-speed strikes
Mantis shrimp are small creatures known for their superlatives. Their eyes have 12 to 16 different color receptors versus our own three, and can detect the polarization of light. Their punches are famously fast, accelerating on par with a 22-caliber.....»»

Researchers find Northern Hemisphere glaciation enhances orbital- and millennial-scale Asian winter monsoon variability
In a study published in Nature Communications, researchers have documented that persistent millennial-scale Asian winter monsoon (AWM) intensity fluctuations were superimposed on 41-kyr and ~100-kyr orbital variability during both the warmer (higher.....»»
Security Bite: Here’s what malware your Mac can detect and remove
Ever wonder what malware macOS can detect and remove without help from third-party software? Apple continuously adds new malware detection rules to Mac’s built-in XProtect suite. While most of the rule names (signatures) are obfuscated, with a bit.....»»
Physicists pioneer new quantum sensing platform
Quantum sensors detect the smallest of environmental changes—for example, an atom reacting to a magnetic field. As these sensors "read" the unique behaviors of subatomic particles, they also dramatically improve scientists' ability to measure and d.....»»
