Phys.org / A mineral from the inside of planets reveals a surprising lesson: How you push matters
In the deepest region of the Earth's mantle, just above the core, much of the material consists of crystals of magnesium oxide. In larger rocky exoplanets called super-Earths, the higher pressures in the lower mantle may ...
Phys.org / Ultrafast light pulses track molecular motion with three-femtosecond resolution
Researchers have observed a molecule in the first instants after it has absorbed light and tracked the coordinated motion of electrons and nuclei with a temporal resolution of three femtoseconds. This is the result achieved ...
Phys.org / A parasite carried by one-third of humanity can't reproduce if one key protein is disabled
A protein discovered in a Virginia Tech–led study may open a gateway to treatments for a parasite responsible for a deadly disease in immunocompromised people. The team led by Raj Gaji, assistant professor of parasitology ...
Phys.org / Clustering changes how charged polymers separate in water, challenging old assumptions
A polymer science revelation about how liquid mixtures separate could have major implications for human health, metabolism and disease, new research indicates. In a brief report published in the Proceedings of the National ...
Phys.org / Reconstructing 16,000 years of summer temperature change in the Western Balkans
Researchers at Eötvös Loránd University (ELTE) have reconstructed approximately 16,000 years of summer temperature changes from sediments collected at Lake Prokoško in Bosnia and Herzegovina. The findings show how the Western ...
Phys.org / Ultrafast light can control ferromagnetism without relying on heating
Despite being known for more mundane uses such as sticking notes to refrigerators or keeping bags shut, magnetization is one of the most fundamental and useful properties of a material. Indeed, it forms the physical basis ...
Phys.org / Custom frame timing captures ultrafast events across five orders of magnitude in time
Most conventional methods of ultrafast photography use evenly spaced intervals in which images are taken, but new developments have shown how much can be left out of the story, especially when multiple timescales are involved.
Phys.org / Normally forbidden emissions from graphene could expose quantum fluctuations in incoming light
Voltage fluctuations, light fluctuations, temperature fluctuations—any fluctuations are troublesome and thus undesirable. They don't just cause discomfort; in engineering and medical applications, they affect the accuracy ...
Phys.org / Enigmatic Mercury will remain a puzzle until someone sends a lander
Mercury remains one of our solar system's most elusive and difficult planets to study. It's easier to send probes to the icy moons of Saturn or Jupiter, or even to Pluto, than to land on our innermost planet, Mercury.
Tech Xplore / Flaws become reinforcements: Engineered crystal defects strengthen metals without changing their chemistry
Scientists have found a way to use defects in crystals to engineer stronger materials, according to a new study.
Phys.org / Plants shift gene activity within minutes of entering spaceflight, experiment reveals
Plants begin responding to spaceflight almost immediately after leaving Earth, according to a new University of Florida study that captured the earliest stages of biological adaptation during a commercial suborbital mission. ...
Phys.org / Even or odd numbers: A single molecule makes all the difference in the quantum world
The researchers in the Quantum Detection Microscopy group at CIC nanoGUNE, in collaboration with chemists at CiQUS of the University of Santiago de Compostela, have demonstrated that adding or removing a single molecule from ...
