Phys.org / Ultrasound-activated nanoparticles in immune cells trigger targeted inflammatory response
Piezoelectric nanoparticles deployed inside immune cells and stimulated remotely by ultrasound can trigger the body's disease-fighting response, according to an interdisciplinary team of Boston College researchers.
Phys.org / Mars was once a 'blue planet': Ancient river deltas point to vast ocean
Using images from cameras on Mars orbiters, an international research team has discovered structures on Mars that are very similar to classic river deltas on Earth. These are traces of rivers that have deposited their sediments ...
Phys.org / Major river deltas are sinking faster than sea-level rise, study shows
A study published in Nature shows that many of the world's major river deltas are sinking faster than sea levels are rising, potentially affecting hundreds of millions of people in these regions.
Phys.org / Scientists demonstrate low-cost, high-quality lenses for super-resolution microscopy
Researchers have shown that consumer-grade 3D printers and low-cost materials can be used to produce multi-element optical components that enable super-resolution imaging, with each lens costing less than $1 to produce. The ...
Phys.org / Tuning spin waves—using commercially available devices at room temperature
Physicist Davide Bossini from the University of Konstanz has recently demonstrated how to change the frequency of the collective magnetic oscillations of a material by up to 40%—using commercially available devices at room ...
Phys.org / 'Death by a thousand cuts': Pablo's galaxy ran out of fuel as black hole choked off supplies
Astronomers have spotted one of the oldest "dead" galaxies yet identified, and found that a growing supermassive black hole can slowly starve a galaxy rather than tear it apart.
Phys.org / Is feeding birds and other wildlife a good thing or a bad thing?
Is that bird feeder in your backyard really helping nature? How about feeding the chipmunks that come to your patio? Or handouts to wildlife in their natural environment, far from human habitation?
Phys.org / A tiny mouse hints at why some mammal mothers may benefit from choosing more than one father
Many animals do something that still surprises researchers: females often mate with more than one male. This behavior—polyandry—has long raised a blunt question. Why divide offspring among multiple fathers, and does it ...
Medical Xpress / How exercise helps aging muscles repair themselves
Scientists at Duke-NUS Medical School have uncovered how exercise helps aging muscles regain their ability to repair themselves, shedding light on why physical activity remains one of the most effective ways to preserve strength ...
Phys.org / Growing up alongside deadly fires inspired me to study them—and fight flames with swarms of drones
Growing up in Greece, wildfires were a constant presence each summer. In 2007, I remember watching TV footage of fires ravaging the Peloponnese peninsula and island of Evia, destroying forests and homes, taking lives. The ...
Phys.org / First standalone spin-wave chip operates without external magnets for future telecom
The Politecnico di Milano has created the first integrated and fully tunable device based on spin waves, opening up new possibilities for the telecommunications of the future, far beyond current 5G and 6G standards. The study, ...
Phys.org / One cure for sour feelings about politics: Getting people to love their hometowns
Eileen Higgins won a historic victory in December. She became the first woman ever elected mayor of Miami, as well as its first Democratic mayor since 1997.
