Phys.org / Mitochondria migrate toward the cell membrane in response to high glucose levels, study shows
Unlike our organs, cell organelles such as mitochondria are not fixed in place, but when, where, how, and why organelles move remain unclear. Research published in the Biophysical Journal shows that when beta cells—the ...
Phys.org / Analysis of Diplodocus dinosaur scales reveals possible speckled color patterning
Scientists have long been trying to reconstruct the appearance of dinosaurs. The tidbits they are able to piece together from fossils and other analysis are displayed in museums, educational materials, and media, lending ...
Phys.org / Physicists make first observation of the pushing pressure of light
(Phys.org)—For more than 100 years, scientists have debated the question: when light travels through a medium such as oil or water, does it pull or push on the medium? While most experiments have found that light exerts ...
Phys.org / 13 years of detailed US CO₂ emissions data released
New research from Northern Arizona University shows detailed CO2 emissions for the United States from 2010 to 2022.
Phys.org / Axolotls regenerate functional thymus after complete removal
The axolotl, a type of salamander that stays in the tadpole form throughout its life, is a master of regeneration. Axolotls have been observed to regrow several body parts, including limbs, eyes, and even parts of their brains.
Phys.org / What is quantum in quantum thermodynamics?
(Phys.org)—A lot of attention has been given to the differences between the quantum and classical worlds. For example, quantum entanglement, superposition, and teleportation are purely quantum phenomena with no classical ...
Phys.org / Medieval peasants probably enjoyed their holiday festivities more than you do
When people think of the European Middle Ages, it often brings to mind grinding poverty, superstition and darkness. But the reality of the 1,000-year period from 500 to 1500 was much more complex. This is especially true ...
Phys.org / Magnetically controlled battery could store energy for power grids
(Phys.org)—Scientists have built a battery containing a magnetic fluid that can be moved in any direction by applying a magnetic field. The magnetically controlled battery concept could be especially useful for flow batteries, ...
Medical Xpress / For teens, any cannabis use may have impact on emotional health and academic performance
Using marijuana just once or twice a month was associated with worse school performance and emotional distress for teens, according to a large national study of adolescents led by Ryan Sultán, an assistant professor of clinical ...
Phys.org / Ghostly solar neutrinos caught transforming carbon atoms deep underground
Neutrinos are one of the most mysterious particles in the universe, often called "ghost particles" because they rarely interact with anything else. Trillions stream through our bodies every second, yet leave no trace. They ...
Phys.org / A simple spin swap reveals exotic anyons
Researchers from the University of Innsbruck, the Collège de France, and the Université Libre de Bruxelles have developed a simple yet powerful method to reveal anyons—exotic quantum particles that are neither bosons ...
Tech Xplore / Tumbleweed aerodynamics inspire hybrid robots for harsh terrains
A new study published in Nature Communications details a hybrid robot that combines the wind-driven mobility of tumbleweeds with active quadcopter control, offering a new paradigm for energy-efficient terrestrial exploration.
