Rootless cones are small volcanic landforms ranging from several to several hundred meters in diameter, formed by continuous explosions resulting from the interaction between surface lava and water bodies like lakes and rivers. Unlike regular volcanoes originating from magma rising from deep underground, rootless cones form when lava covers a water-containing layer, triggering explosive reactions.
Researchers from Oakland University have made a significant breakthrough in the field of optical materials, unveiling the exceptional capabilities of Ba₃(ZnB₅O₁₀)PO₄ (BZBP). Although this transparent crystal closely resembles ordinary window glass, it exhibits extraordinary properties that set it apart from others.
Interactions between atoms and light rule the behavior of our physical world, but at the same time, can be extremely complex. Understanding and harnessing them is one of the major challenges for the development of quantum technologies.
As space travel gains traction and astronauts spend increasing amounts of time in space, studying its effects on health has become increasingly critical.
“You don’t have authority to tell me to get on the ground,” the man said as he ran backward toward the Salt Lake City cruiser and bystander vehicle
Southwest Research Institute partnered with the Carnegie Institution for Science to perform laboratory experiments to better understand how Saturn’s moon Titan can maintain its unique nitrogen-rich atmosphere. Titan is the second largest moon in our solar system and the only one that has a significant atmosphere.
This NASA/ESA Hubble Space Telescope image features a dusty yet sparkling scene from one of the Milky Way’s satellite galaxies, the Large Magellanic Cloud. The Large Magellanic Cloud is a dwarf galaxy situated about 160,000 light-years away in the constellations Dorado and Mensa.
A hundred years ago, astronomer Edwin Hubble dramatically expanded the size of the known universe. At a meeting of the American Astronomical Society in January 1925, a paper read by one of his colleagues on his behalf reported that the Andromeda nebula, also called M31, was nearly a million light years away—too remote to be a part of the Milky Way.
Researchers have pioneered an innovative method using helioseismology to measure the solar radiative opacity under extreme conditions. Their work, published in Nature Communications, not only reveals gaps in our understanding of atomic physics but also confirms recent experimental results, thereby opening new perspectives in astrophysics and nuclear physics.
About 99% of Earth is uninhabitable; in deep underground places with high pressure and temperature, even the toughest bacteria cannot survive. However, there are places where life thrives, from tiniest toughest bacteria to the largest elephant. Then there are places that are habitable but are devoid of life; lava flows are a great example, as is the space between microbes. A new paper looks at these uninhabited yet habitable areas and considers what we may learn as we search for life in the universe.
A research team has discovered that achiral hard banana-shaped particles can spontaneously form exotic structures like skyrmions and blue phase III phases. Skyrmions are tiny vortex-like structures found in various condensed-matter systems, such as helical ferromagnets and liquid crystals. Blue phase III is an amorphous phase of liquid crystals that possesses strong optical activity. Achiral particles are particles that can be superimposed on their mirror image. The team’s findings have potential applications in photonics and memory devices.
Ex-N.Y. trooper who said he was shot on duty turns self in on evidence tampering, misconduct chargesThe former trooper reported that he had been shot after he stopped to check on a stranded motorist in October 2024
Ever since Isaac Newton famously talked about gravity, its dominance as a force in our solar system has been well known. It’s responsible for the orbits of the planets and their satellites, but there are other forces that have shaped our planetary neighborhood.
There might be a type of exoplanet without dry land. They’re called “Hycean” worlds, a portmanteau of “hydrogen” and “ocean.” They’re mostly or entirely covered in oceans and have thick hydrogen atmospheres.
Teams with NASA’s Exploration Ground Systems Program continue stacking the SLS (Space Launch System) rocket’s twin solid rocket booster motor segments for the agency’s Artemis II mission, inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida.
