Investigating dense plasmas with positron waves
Astrophysical and lab-created plasmas under the influence of magnetic fields are the source of intense study. New research seeks to understand the dynamics of position waves traveling through these clouds of highly ionized gas......»»
A deeper dive into wintry, carbon-absorbing Antarctic waters
Every year as the austral winter sets in, frigid Antarctic air blasts the Southern Ocean. The chill dissipates the warmth of the ocean's surface water, and cold, dense layers form in the sea's upper reaches. Known as Subantarctic Mode Water (SAMW), t.....»»
Lunar telescope project aims to search for ancient radio waves
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are leading a new effort to land a radio telescope on the moon. If successful, the project will mark the first step towards exploring the Dark Ages of the universe......»»
A better understanding of gas exchange between the atmosphere and ocean can improve global climate models
The injection of bubbles from waves breaking in turbulent and cold high-latitude regions of the high seas is an underappreciated way in which atmospheric gases are transported into the interior ocean. An improved mechanistic understanding of gas exch.....»»
Hollow bones that let dinosaurs become giants evolved at least three times independently, shows study
Dinosaurs as big as buses or five-story buildings would not be possible if their bones were dense and heavy like ours. Like present-day birds, dinosaurs had hollow bones with inner structures known as air sacs, which made their skeletons lighter and.....»»
NHTSA investigating how Zoox self-certified its robotaxi
NHTSA said in a filing made public Monday that it will examine the process and technical data that Amazon-owned Zoox relied on when certifying that its robotaxi met federal requirements to travel on public roads......»»
A warmer world will make heat waves more frequent, says study
From late June to early July 2021, an unprecedented heat wave swept across Western North America (WNA), causing considerable hazards to the regional society and economy. What is the likelihood of a similar heat wave under global warming?.....»»
Forescout XDR enables SOC teams to reduce the attack surface
Forescout revealed Forescout XDR, a solution designed to aid enterprises in detecting, investigating, and responding to an extensive range of sophisticated threats throughout their extended enterprise. A typical SOC is flooded with 450 alerts per hou.....»»
Digital technologies to better predict future city environments may be key tool in sustainable urban design
Natural disasters like floods and heat waves demonstrate the real lack of control people have over the environment—although some of those disasters may actually be a consequence of human decisions and carelessness......»»
Investigation of powder in air reveals it was pollen
West Virginia officials investigating reports of a powder in the air and on some vehicles in the mid-Atlantic have determined the source: pollen......»»
Illuminating the science of black holes and gamma-ray bursts using high-power lasers
High-power lasers now create record-high numbers of electron-positron pairs, opening exciting opportunities to study extreme astrophysical processes, such as black holes and gamma-ray bursts......»»
Observing phononic skyrmions based on the hybrid spin of elastic waves
Skyrmions are extremely small with diameters in the nanoscale, and they behave as particles suited for information storage and logic technologies. In 1961, Tony Skyrme formulated a manifestation of the first topological defect to model a particle and.....»»
Investigating factors that affect consumer attitudes about organic food
Researchers, publishing in the International Journal of Green Economics, have investigated the many factors that affect consumer attitudes and buying habits when it comes to organic food products. Mohd Farhan of the Mittal School of Business in Punja.....»»
Russia"s aggression threatens efforts to protect nature beyond Ukraine, say researchers
The Russian invasion of Ukraine launched in February 2022 has sent economic, social and political shock waves around the world. In a newly published policy brief, we and other researchers and conservation scientists describe how these effects extend.....»»
Deadly waves: Researchers document the evolution of plague over hundreds of years in medieval Denmark
Scientists who study the origins and evolution of the plague have examined hundreds of ancient human teeth from Denmark, seeking to address longstanding questions about its arrival, persistence and spread within Scandinavia......»»
Amazon closes $3.9 billion deal to acquire One Medical

Investigating land subsidence in Japan through consecutive DInSAR and the law of material conservation
Land subsidence is a phenomenon wherein the Earth's surface sinks downwards. It occurs mainly due to human activities, such as excessive groundwater extraction. It is a major global concern, affecting 19% of the world's population. In Japan, some par.....»»
Russia claims an “external impact” damaged its Progress spacecraft
Two Russian spacecraft in two months have been struck this way. Supposedly. Enlarge / The European robotic arm is seen investigating Soyuz MS-22 after a leak occurred in mid-December. (credit: NASA TV) Russia's main spac.....»»
Physicists create new model of ringing black holes
When two black holes collide into each other to form a new bigger black hole, they violently roil spacetime around them, sending ripples, called gravitational waves, outward in all directions. Previous studies of black hole collisions modeled the beh.....»»
Bouncing seismic waves reveal distinct layer in Earth"s inner core
Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth's inner core, according to seismologists from The Australian National University (ANU)......»»
