Shining a light on synthetic dimensions

Humans experience the world in three dimensions, but a collaboration in Japan has developed a way to create synthetic dimensions to better understand the fundamental laws of the universe and possibly apply them to advanced ...

Extreme exoplanet has a complex and exotic atmosphere

An international team including researchers from the University of Bern and the University of Geneva as well as the National Centre of Competence in Research (NCCR) PlanetS analyzed the atmosphere of one of the most extreme ...

Highest resolution view of the heart of a blazar achieved

An international team, including several researchers from the Max Planck Institute for Radio Astronomy in Bonn, has mapped the active galaxy OJ 287 with an angular resolution of 12 microarcseconds in the radio range. This ...

Blocking sphingolipids counteracts muscular dystrophy

EPFL scientists have made the first link between muscular dystrophy and a group of bioactive fats, the sphingolipids, which are involved in numerous cell functions and other diseases.

Developing a smartphone app for flu and COVID detection

In a potential game changer for COVID-19 pandemic control efforts, a new cell phone app and lab kit have transformed a smartphone into a COVID-19 / flu detection system. The detection system is among the most rapid, sensitive, ...

Researchers discover how lactic acid weakens anti-tumor defenses

In cancer research, it has long been known that lactic acid, or lactate, is produced in large quantities by cancer cells and that this lactic acid disrupts our defense against tumors. Until now, however, we did not know exactly ...

Mutant stem cells defy rules of development

Imagine you're baking a cake, but you run out of salt. Even with the missing ingredient, the batter still looks like cake batter, so you stick it in the oven and cross your fingers, expecting to end up with something pretty ...

Solving a superconducting mystery with more precise computations

Researchers have known about high-temperature superconducting copper-based materials, or cuprates, since the 1980s. Below a certain temperature (approximately -130 degree Celsius), electrical resistance vanishes from these ...

New approach transports trapped ions to create entangling gates

Trapped ions excited with a laser beam can be used to create entangled qubits in quantum information systems, but addressing several stationary pairs of ions in a trap requires multiple optical switches and complex controls. ...

Stool samples reveal microbial enzyme driving bowel disease

Ulcerative colitis, a subtype of inflammatory bowel disease, is a chronic ailment of the colon affecting nearly one million individuals in the United States. It is thought to be linked to disruptions in the gut microbiome—the ...

NASA planes fly into snowstorms to study snowfall

Scientists repeatedly check the weather forecasts as they prepare aircraft for flight and perform last-minute checks on science instruments. There's a large winter storm rolling in, but that's exactly what these storm-chasing ...

Consumer sentiment sinks to decade low

Consumer sentiment fell throughout January, posting a cumulative loss of 4.8%, sinking to its lowest level since November 2011, according to the University of Michigan Surveys of Consumers.

Greece: Rescue operation to help stranded young whale

Divers, vets and the coast guard were mounting a rescue operation Friday to help a whale calf that had become trapped in shallow water in a seaside area of the Greek capital, but tests carried out on the animal showed it ...

High mountain rain has scientists rethinking river basics

Mountainous terrains have dynamic climates and can produce startling contrasts in precipitation. Increases in elevation can spell either more or less rainfall depending on atmospheric moisture content, general circulation ...

Revolutionizing satellite power using laser beaming

The University of Surrey and Space Power are tackling the problem of powering satellites in Low Earth Orbit (LEO) during their eclipse period when they cannot see the sun. By collaborating on a space infrastructure project, ...

Thawing permafrost can accelerate global warming

Thawing permafrost in the Arctic could be emitting greenhouse gasses from previously unaccounted-for carbon stocks, fuelling global warming. That is the result of a study conducted by a team of geologists led by Professor ...

A four-megabit nvCIM macro for edge AI devices

Edge AI devices, systems that combine artificial intelligence (AI) and edge computing techniques, are becoming an essential part of the rapidly growing Internet of Things (IoT) ecosystem. These devices include smart speakers, ...

Why Gambia should fast-track gender quotas for women

Women have historically been poorly represented in positions of power and decision-making in Gambia. Out of 58 National Assembly members, only six are women lawmakers and only three of these are elected. Women make up more ...

What is a bomb cyclone? An atmospheric scientist explains

A bomb cyclone is a large, intense midlatitude storm that has low pressure at its center, weather fronts and an array of associated weather, from blizzards to severe thunderstorms to heavy precipitation. It becomes a bomb ...
