Giant rogue waves: Southern Ocean expedition reveals wind as key cause
A University of Melbourne expedition to the southernmost waters encircling Antarctica has discovered that wind drives the formation of colossal rogue waves, and that these unpredictable waves occur more frequently than scientists had previously thoug.....»»
Tandem heat waves, storm surges increasingly batter coasts: Study
Coastal communities need to prepare for simultaneous extreme weather events as heat waves increasingly overlap with surges in sea levels due to climate change, a study published on Thursday warned......»»
How new tech is making geothermal energy a more versatile power source
Geothermal has moved beyond being confined to areas with volcanic activity. Enlarge / The Nesjavellir Geothermal Power Station. Geothermal power has long been popular in volcanic countries like Iceland, where hot water bubbles fr.....»»
Study identifies increased threat to coastlines from concurrent heat waves and sea level rises
Concurrent occurrences of heat waves and extreme short-term sea level rises at the same coastal locations significantly increased between 1998 and 2017 when compared to the preceding 20 years, reports a study published in Communications Earth & Envir.....»»

Electro-optic 3D snapshot of a laser wakefield accelerated kilo-ampere electron bunch
Invented by T. Tajima and J. Dawson, laser wakefield acceleration (LWFA) harnesses the power of high-intensity laser pulses to drive plasma waves with acceleration gradients orders of magnitude higher than conventional RF-based accelerators......»»
What could we build with lunar regolith?
It has often been likened to talcum powder. The ultra fine lunar surface material known as the regolith is crushed volcanic rock. For visitors to the surface of the moon it can be a health hazard, causing wear and tear on astronauts and their equipme.....»»
Gravitational waves reveal “mystery object” merging with a neutron star
The so-called "mass gap" might be less empty than physicists previously thought. Enlarge / Artistic rendition of a black hole merging with a neutron star. LIGO/VIRGO/KAGRA detected a merger involving a neutron star and what might.....»»
Deep parts of Great Barrier Reef "insulated" from global warming, for now
Some deeper areas of the Great Barrier Reef are insulated from harmful heat waves—but that protection will be lost if global warming continues, according to new research......»»
High-performance terahertz modulators induced by substrate field in Te-based all-2D heterojunctions
High-performance active terahertz (THz) modulators are of great importance for next generation communication technology. However, they currently suffer from the tradeoff between modulation depth and speed......»»
Propagating dimensions of light: Deforming versatile non-diffractive beams along the optical trajectory
The diffraction of light is a ubiquitous phenomenon in nature where waves spread out as they propagate. This spreading of light beams during propagation limits the efficient transmission of energy and information. Therefore, scientists have endeavore.....»»
Innovative sensing platform unlocks ultrahigh sensitivity in conventional sensors
Optical sensors serve as the backbone of numerous scientific and technological endeavors, from detecting gravitational waves to imaging biological tissues for medical diagnostics. These sensors use light to detect changes in the properties of the env.....»»
Kerr-enhanced optical spring for next-generation gravitational wave detectors
The detection of gravitational waves stands as one of the most significant achievements in modern physics. In 2017, gravitational waves from the merger of a binary neutron star were detected for the first time which uncovered crucial information abou.....»»
Ocean waves propel PFAS back to land, new study finds
A new study by researchers at the Department of Environmental Science, Stockholm University, published in Science Advances, reveals that PFAS re-emit into the air from crashing ocean waves at levels comparable to or greater than other sources, establ.....»»
Omni Hotels suffer prolonged IT outage due to cyberattack
Texas-based Omni Hotels & Resorts has been responding to a cyberattack that started last Friday, which resulted in the unavailability of many of its IT systems. According to people staying at some of the 50 properties the company operates across Nort.....»»
