Phys.org / Why no individual is like another when epigenetics come into play
Why do animals behave differently, and what are the consequences of this? A research team from the Collaborative Research Center NC³ at Bielefeld University and the University of Münster now provides a new explanation: epigenetic ...
Phys.org / Silicon nanospheres boost WS₂ second-harmonic generation 40-fold while preserving polarization
A research team has demonstrated that silicon nanospheres can strongly enhance second-harmonic generation (SHG) from an atomically thin semiconductor while preserving the circular polarization information tied to its valley ...
Phys.org / Seismic activity in California varies with the seasons
Earthquakes occur when the tectonic plates of the Earth's crust shift, jolting past each other in a release of built-up tension. However, other natural forces can also influence seismic activity: Hydrological dynamics, like ...
Phys.org / How plants stop growing to survive stress: Retired scientist's persistence reveals insight to boost farm yields
UC Riverside researchers have identified a mechanism that allows plants to rapidly slow growth in response to extreme environmental stress. The finding could help farmers grow more resilient crops, and one researcher continued ...
Phys.org / It's go time: historic Moon mission set for lift-off
More than half a century after the groundbreaking Apollo program's last crewed flight to the moon, three men and one woman are preparing for a lunar journey set to turn a new page in American space exploration.
Phys.org / Making quantum vibrations nonlinear to enable phonon-phonon interactions
Phonons are the quantum units of mechanical vibration. They describe how motion propagates through a solid at the smallest possible scales, in much the same way that electrons describe electric currents. Because phonons can ...
Phys.org / How the body senses cold has been a mystery—until now
When you reach into a bucket of ice, open your front door on a snowy day, or feel the tingle of menthol toothpaste, a protein in your nerve cells called TRPM8 springs into action, opening like a tiny gate to send a "cold" ...
Phys.org / XRISM clocks hot wind of galaxy M82 at 2 million mph
For the first time, astronomers have directly measured the speed of superheated gas billowing from a cauldron of stellar activity at the heart of M82, a nearby galaxy undergoing an extraordinary burst of star formation. The ...
Phys.org / Advanced dating method reveals age of Pacific coral architecture
Application of an advanced dating technique establishes the first precise construction timeline for houses built out of coral in French Polynesia. The findings reveal previously hidden patterns of architectural development ...
Phys.org / If the Laschamps geomagnetic excursion happened today, aviation radiation exposure would be radically altered
Earth's magnetic field acts as a vital shield against radiation arriving from space, but it is not constant. A new international study has examined how a reduction of the magnetic field similar to the Laschamps excursion ...
Phys.org / Britain's hibernating hazel dormice are getting lighter in spring as temperatures rise, study suggests
Britain's hazel dormice are getting lighter in spring but fatter in autumn as our climate changes, suggests new research in Scientific Reports. The study, titled "The effects of climate and land cover on hazel dormouse (Muscardinus ...
Phys.org / Now you see it, now you don't: Material can transition between quantum states
A team of scientists led by the U.S. Department of Energy's (DOE) Argonne National Laboratory has identified a rare, switchable quantum property in a new type of nickel sulfide material. The discovery could have applications ...
