Energy loss triggers quantum thermal Hall-like effect at macroscopic scale

In many quantum materials—materials with unusual electrical and magnetic properties driven by quantum mechanical effects—electrons can organize themselves into Landau levels. Landau levels are essentially quantized energy states that form when charged particles move in a magnetic field.

Tackling industry’s burdensome bubble problem

In industrial plants around the world, tiny bubbles cause big problems. Bubbles clog filters, disrupt chemical reactions, reduce throughput during biomanufacturing, and can even cause overheating in electronics and nuclear power plants. MIT Professor Kripa Varanasi has long studied methods to reduce bubble disruption.

How did Cleopatra die?

Cleopatra VII the queen of Egypt and one of the most famous women in history. Cleopatra rules over the prosperous Egyptian empire. She is beautiful, intelligent, and a master of manipulation. Every man she meets falls in love with her, including Julius Caesar and Mark Antony.

Over time, Cleopatra’s ambitions grow, and she becomes […]

A puddle that jumps: What bubble bursts reveal about water on lotus-like surfaces

Water droplets have a unique ability: They can leap from a surface on their own. This can happen for a variety of reasons, such as when a surface repels water or when heat is involved, such as a water or oil droplet skittering across a hot pan.

Apollo moon rocks reveal lunar magnetic field was briefly stronger than Earth’s

Researchers from the Department of Earth Sciences, University of Oxford, have resolved a long-standing debate about the strength of the moon’s magnetic field. For decades, scientists have argued about whether the moon had a strong or weak magnetic field during its early history (3.5–4 billion years ago). Now a new analysis, published in Nature Geoscience, […]

Who was Cleopatra

When we hear the name Cleopatra, we think of a beautiful and alluring woman with a tragic story. But who was she? Cleopatra was the last active pharaoh of Ptolemaic Egypt and briefly survived as pharaoh by her son Caesarion. After her reign, Egypt became a province of the Roman Empire.

Cleopatra was a […]

A world first at the microscopic scale: Metamaterials that can shrink and expand on their own

Leiden physicists Daniela Kraft and Julio Melio have created soft structures that can take on different shapes without any external drive in their lab. They present their research on microscale metamaterials in Nature—a breakthrough that opens the door to smart, reconfigurable materials and microscopic robots.

A robust new telecom qubit identified in silicon

Quantum technologies are anticipated to transform computing, communication, and sensing by harnessing the unusual behavior of matter at the atomic scale. Translating quantum’s promise into practical devices will require physical systems that have desirable quantum properties and can be easily manufactured. Silicon, the material behind today’s computer chips, is highly attractive as a platform because […]

Farming on the moon or Mars? How recycled sewage could turn regolith into crop soil

Dining on the moon or Mars might seem like a fantasy reserved for science fiction, but researchers are investigating how it could become a reality. Their efforts to recycle plant and human waste into a fertilizer material—turning the barren surfaces of the moon and Mars into fertile fields that might be suitable for extraterrestrial agriculture—are […]

Why Mars astronauts need more than just space greenhouses

Thinking about food systems in deep space likely brings to mind something like The Martian where an astronaut is scratching barely enough food to survive out of potatoes grown in Martian regolith. Or perhaps a fancy hydroponic system on an interplanetary transport ship, with artificial lighting and all the associated technological wizardry. But a new […]

Webb examines ‘Exposed Cranium’ nebula

Two heads are better than one in the latest images from NASA’s James Webb Space Telescope, which reveal new detail in a mysterious, little-studied nebula surrounding a dying star. Nebula PMR 1 is a cloud of gas and dust that bears an uncanny resemblance to a brain in a transparent skull, inspiring its nickname, the […]

Ion bombardment triggers a reliable quantum switch in tantalum disulfide crystals

When you toss a coin, you put it into a higher-energy state until it falls back down again. It can then end up in one of two possible states: heads or tails. No matter which state the coin was in before, after the toss both outcomes are equally likely. A team at TU Wien has […]
