In theoretical research that could explain everything from planet formation to outflows from stars to even the settling of volcanic ash, Caltech researchers have discovered a new mechanism to explain how the act of dust moving through gas leads to clumps of dust
Physics is the science of matter, energy, space and time. It looks both inward and outward, from the smallest subatomic particle to the vastness of the universe—and yet it is also intensely practical. Physics begins with the everyday physical world around us—the blue of the sky, the colors of the rainbow, the fall of an apple, the motions of the moon. What's happening here? Why do things work this way?
Columbia engineers have made white paint whiter -- and cooler -- by removing white pigment and inventing a polymer coating, with nano- to microscale air voids, that acts as a spontaneous air cooler and can be fabricated, dyed and applied like paint
A recent study shows that in fire ant colonies, a small number of workers does most of the digging
The world's largest outdoor earthquake simulator, operated by structural engineers at the University of California, San Diego, has received a $16.3 million grant from the National Science Foundation to upgrade the facility to expand its testing capabilities
How have radio telescope discoveries impacted materials science?
How can someone discover a real planet in the solar system? Michael Brown of the California Institute of Technology answers the question in this special "Mysteries of the Cosmos" edition of "Ask a Scientist"
A team of Harvard University researchers spent months shaking and rattling swarms of thousands of honeybees to better understand how bees collectively collaborate to stabilize structures in the presence of external loads such as wind and rain
Four young scientists compete to give the best (and most-entertaining) three-minute explanation of a significant aspect of quantum technology to a family audience at the Museum of Science, Boston
Scientists have teamed up to create stretchable, flexible wires that conduct current and change colors to indicate that they're about to reach the breaking point
A structure that's part bow tie, part funnel that concentrates light powerfully and nearly indefinitely could make computers faster than microelectronics can
Harvard University researchers have developed a new printing method that uses soundwaves to generate droplets from liquids with an unprecedented range of composition and viscosity. This technique could finally enable the manufacturing of many new biopharmaceuticals, cosmetics, and food and expand the possibilities of optical and conductive materials.
Survival of the laziest, weather whiplash and more
Why isn't Pluto a planet anymore? And what is a planet anyway? Astrophysicist Jackie Faherty explains!
National Science Foundation-funded researchers at Duke University have discovered how uniquely shaped artificial material or metamaterial can control the transmission, redirection and reflection of sound waves with almost perfect efficiency
Researchers at Texas A&M University and Stevens Institute of Technology are laying groundwork to develop the next generation of biomedical materials used to treat chronic wounds
Researchers at Washington University in St. Louis took the classical Maxwell's Demon experiment to smaller scales as they worked out a quantum theory of thermodynamics
Genes turn on, fluids go surfing, radioactivity spills from a cosmic collision and an oceanic plate crashes the party at Earth's mantle
A team of scientists has introduced a new approach to assemble specially designed microscopic blocks into small, gear-like machines
A collaborative team, including researcher at the School of Engineering & Applied Science and the School of Medicine at Washington University in St. Louis, develops a new nanoparticle patch designed to boost brightness in certain diagnostic tests
With support from the National Science Foundation, geologist Jeff Moore and his team are pioneering a new method of structural health monitoring to keep tabs on the structural integrity of spectacular geological landmarks
