A new way to control the magnetic properties of rare earth elements
The special properties of rare earth magnetic materials are due to the electrons in the 4f shell. Until now, the magnetic properties of 4f electrons were considered almost impossible to control......»»
NASA sounding rocket launches, studies heating of sun"s active regions
Investigators at NASA's Marshall Space Flight Center in Huntsville, Alabama, will use observations from a recently-launched sounding rocket mission to provide a clearer image of how and why the sun's corona grows so much hotter than the visible surfa.....»»
Research team observes courtship of leopard seals off the coast of South America
A study led by Baylor University biologist Sarah Kienle, Ph.D., and published in the journal Polar Biology has unveiled the first paired observations of sexual behavior and vocalizations in wild leopard seals. Kienle and her team's third published st.....»»
Tropical plant species are as threatened by climate change as widely feared, study confirms
Brown University biologists who set out to better understand the effects of climate change on plant species in tropical mountain regions found that even small variations in temperature and moisture can have massive impacts, threatening not only plant.....»»
Observations detect a nearby hypervelocity stellar/substellar object
Using the Keck II telescope, astronomers have detected an object that may be a brown dwarf or a low-mass star, exhibiting a very high radial velocity. The object, designated CWISE J124909.08+362116.0 is located some 400 light years away. The finding.....»»
How a futuristic material is able to change its properties from soft to rigid, and back again
In our everyday life, we are surrounded by objects that have properties enabling them to perform certain functions. Rigidity and softness enable an object to perform a specific function. These properties are seemingly opposing in nature, and one prop.....»»

Mega-iceberg melt affects important marine ecosystem
Scientists have for the first time taken in-situ ocean measurements during the collapse of a giant iceberg in the sub-Antarctic. These new observations reveal how ocean ecosystems may be affected if more icebergs calve due to warmer ocean temperature.....»»
Study shows how organic molecules impact gold nanoparticles" electrochemical properties
A new study shows how organic molecules greatly influence the redox potential of gold nanoparticles, with differences up to 71 mV. Using experiments and computer simulations, the study highlights the important role of capping agents in controlling th.....»»
Researchers reveal parsec-scale radio emission properties of dual AGNs by multi-phase-center VLBI observations
Galaxy mergers play a crucial role in the cosmological evolution of galaxies. During galaxy merging, tidal torques can trigger the accretion and feedback of the central black holes in merging galaxies, forming dual active galactic nuclei (AGNs)......»»
AI method radically speeds predictions of materials" thermal properties
It is estimated that about 70% of the energy generated worldwide ends up as waste heat......»»
Grain boundaries weaken in planetary interiors, research suggests
Mantle convection and associated plate tectonics of planets like the Earth are governed by the deformation of mantle rocks. This deformation occurs through the motion of defects in the crystal lattices of minerals. Thus, the physical properties of th.....»»
Penske Automotive buys Bill Brown Ford, the world"s largest Ford dealership
Penske said it estimates the suburban Detroit dealership, founded in 1941 by the Brown family, will add $550 million in annual revenue. The dealership's name will stay the same. .....»»
Studies investigate the impact of agriculture on air quality in Lombardy
In the wake of the 2020 COVID-19 lockdowns, researchers in northern Italy noticed that notwithstanding the partial suspension of travel and industrial production in the region, the level of particulate matter in the atmosphere remained high......»»
Observatory gears up to detect thousands of elusive brown dwarfs, unlocking Milky Way mysteries
One could argue that brown dwarfs don't get the love they deserve. Sometimes referred to as "failed stars," they don't have enough mass to sustain nuclear fusion, which powers all stars, including our sun. But they are also too big to be considered p.....»»
How climate change is altering the Earth"s rotation
For the first time, researchers at ETH Zurich have been able to fully explain the various causes of long-term polar motion in the most comprehensive modeling to date, using AI methods. Their model and their observations show that climate change and g.....»»
Solar flares and solar magnetic reconnection get new spotlight in two blazing studies
Two recent studies published in The Astrophysical Journal discuss findings regarding solar flare properties and a new classification index and the sun's magnetic field, specifically what's called solar magnetic reconnection......»»
Webb unveils stunning ejecta and CO structures in Cassiopeia A"s young supernova
The SETI Institute announced the latest findings from the James Webb Space Telescope (JWST) of the supernova remnant, Cassiopeia A (Cas A). These observations of the youngest known core collapse supernova in the Milky Way provide insights into the co.....»»
Nearby exoplanet could be first known ocean world: Webb telescope
A planet relatively close to Earth could be the first ever detected with a potentially life-sustaining liquid ocean outside our Solar System, according to scientists using the James Webb space telescope......»»
