Phys.org / Ultrathin silicon structures can tune mid-IR light in billionths of a second
Light in the mid-infrared (mid-IR) portion of the electromagnetic spectrum plays a key role in modern sensing. Because molecules interact with this kind of light in specific ways, researchers use technologies like mid-IR ...
Phys.org / 'CRISPR-Combo' system speeds regeneration of hard-to-breed perennial crops
Editing a plant's genes is only half the battle. Before a new, improved trait can ever reach a farmer's field, scientists must be able to grow a whole plant from just a few edited cells—a process that can be slow, unreliable ...
Phys.org / Unveiling how nanoparticles create iridescence in ancient ceramics
Scientists led by the Universitat Politècnica de Barcelona and the ESRF, the European Synchrotron, have revealed the chemical reactions in nanoparticles that created a unique, shimmering effect in the painting on ninth-century ...
Phys.org / Himalayan glacial lakes are growing—and so is the downstream flood risk
Dozens of glacial lakes have formed across northern India in the last three decades, while existing lakes have expanded rapidly, highlighting the need to monitor a landscape reshaped by climate change.
Phys.org / Global database reveals why no two cities' food emissions look the same
Switching to a more sustainable diet could halve food-related emissions in cities such as Amsterdam, while in cities such as Dhaka and Delhi, the focus should be more on making food production more sustainable as they widen ...
Phys.org / 'White graphene' reshaped at the atomic scale with tailor-made nanopores
A research team at the University of Vienna led by physicist Jani Kotakoski demonstrates how the shape of nanopores in hexagonal boron nitride—the electrically insulating counterpart to graphene, also known as "white graphene"—can ...
Phys.org / Scientists want to 3D print houses on Mars with the help of yeast
Mars is a terrible place to build a house. It's bitterly cold, blasted by radiation and a near vacuum. Not to mention that the building materials, even for a modest shelter, could spend months hurtling through space before ...
Phys.org / 'Fingerprints' inside the sun could reveal if it once swallowed a planet
It is thought the sun may have engulfed a super-Earth-sized planet early in its history. Now, a new study has gone a step further, suggesting that such an event may have left behind detectable clues inside the sun that could ...
Phys.org / Sun's largest sunspots may have potential to trigger superflares
The sun is capable of great things. In massive eruptions, it repeatedly hurls particles and radiation into space. This solar bombardment can be dangerous for technical infrastructure on Earth: For example, satellites and ...
Phys.org / Under pressure: How a deep-sea protein adapts to an extreme environment
Life in the deep sea is under immense pressure—literally. Such extreme conditions can disrupt the delicate structures of proteins essential to life. Yet somehow, the proteins in deep-sea creatures remain functional. This ...
Phys.org / BepiColombo measures Mercury's particle bombardment up close
The joint BepiColombo mission of the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) is settling into orbit around Mercury after an eight-year journey. In early September, BepiColombo's two orbiters, ...
Phys.org / A cellular threshold can determine whether herpesvirus becomes active or lies dormant
During the COVID-19 pandemic, we wore masks and kept 2 meters (6.6 feet) apart in an effort to reduce the spread of the tiny droplets we release into the air with every breath, conversation or cough. The main goal was to ...
