Portable device helps doctors diagnose sepsis faster
Portable device helps doctors diagnose sepsis faster
EPFL researchers have developed a highly sensitive and portable optical biosensor that stands to accelerate the diagnosis of fatal conditions like sepsis. It could be used by ambulances and hospitals to improve the triage process and save lives. Sepsis claims one life every four seconds. It is the primary cause of death in hospitals, and one of the ten leading causes of death worldwide.

Uses physics to explain democratic elections
Uses physics to explain democratic elections
U.S. elections have become more "unstable," sometimes swinging in the opposite direction from the greater electorate's preferences. It may seem surprising, but theories and formulas derived from physics turn out to be useful tools for understanding the ways democratic elections work, including how these systems break down and how they could be improved.

Platelets instead of spheres make screens more economical
Platelets instead of spheres make screens more economical
ETH scientists have further developed QLED technology for screens. They have produced light sources that for the first time emit high-intensity light in only one direction. This reduces scattering losses, which makes the technology extremely energy efficient. QLED screens have been on the market for a few years now.

Record-breaking Terahertz Laser Beam
Record-breaking Terahertz Laser Beam
A new, extremely efficient source of terahertz radiation has been developed at TU Wien (Vienna): Lasers turn air into plasma, thereby producing terahertz rays for many possible applications. Terahertz radiation is used for security checks at airports, for medical examinations and also for quality checks in industry.

Ultrafast Camera Takes 1 Trillion Frames Per Second of Transparent Objects and Phenomena
A little over a year ago, Caltech's Lihong Wang developed the world's fastest camera, a device capable of taking 10 trillion pictures per second. It is so fast that it can even capture light traveling in slow motion. But sometimes just being quick is not enough. Indeed, not even the fastest camera can take pictures of things it cannot see.

Chemists allow boron atoms to migrate
Chemists allow boron atoms to migrate
Organic molecules with atoms of the semi-metal boron are among the most important building blocks for synthesis products that are needed to produce drugs and agricultural chemicals. However, during the usual chemical reactions used in industry, the valuable boron unit, which can replace another atom in a molecule, is often lost.

A New Look at
A New Look at "Strange Metals"
For years, a new synthesis method has been developed at TU Wien (Vienna) to unlock the secrets of "strange metals". Now a breakthrough has been achieved. The results have been published in "Science". Superconductors allow electrical current to flow without any resistance - but only below a certain critical temperature.

Finds billions of quantum entangled electrons in 'strange metal'
Finds billions of quantum entangled electrons in ’strange metal’
Physicists provide direct evidence of entanglement's role in quantum criticality In a new study, U.S. and Austrian physicists have observed quantum entanglement among "billions of billions” of flowing electrons in a quantum critical material. The research, which appears this week in Science, examined the electronic and magnetic behavior of a "strange metal” compound of ytterbium, rhodium and silicon as it both neared and passed through a critical transition at the boundary between two well-studied quantum phases.

Class of strange objects near our galaxy’s enormous black hole
Astronomers from UCLA's Galactic Center Orbits Initiative have discovered a new class of bizarre objects at the center of our galaxy, not far from the supermassive black hole called Sagittarius A*. They published their research in the Jan. 16 issue of the journal Nature. “These objects look like gas and behave like stars,” said co-author Andrea Ghez, UCLA's Lauren B. Leichtman and Arthur E. Levine Professor of Astrophysics and director of the UCLA Galactic Center Group.

Interstellar journey of life's building block phosphorus unveiled
Interstellar journey of life’s building block phosphorus unveiled
Phosphorus, present in our DNA and cell membranes, is an essential element for life. But how it became available on the early Earth when life appeared here about 4 billion years ago is something of a mystery. For the first time, astronomers - among them researchers from the University of Bern - have now been able to show that molecules with phosphorus are formed in star-forming regions and probably came to Earth with comets.

Colloidal quantum dot laser diodes are just around the corner
Researchers reach a critical milestone on the path to versatile colloidal quantum dot laser diodes by successfully demonstrating a quantum dot LED that also operates as an optically pumped laser This latest breakthrough along with other recent advances in quantum dot chemistry and device engineering that we have achieved suggest that laser diodes assembled from solution may soon become a reality.

X-rays and gravitational waves will combine to illuminate massive black hole collisions
A new study by a group of researchers at the University of Birmingham has found that collisions of supermassive black holes may be simultaneously observable in both gravitational waves and X-rays at the beginning of the next decade. The European Space Agency (ESA) has recently announced that its two major space observatories of the 2030s will have their launches timed for simultaneous use.

Galactic gamma-ray sources reveal birthplaces of high-energy particles
Researchers with the joint US-Mexico-European HAWC Observatory have identified a host of galactic sources of super-high-energy gamma rays The Earth is constantly being bombarded with charged particles called cosmic rays, but because they are charged, they bend in magnetic fields and don't point back to their sources.

Preparing for the hydrogen economy
Preparing for the hydrogen economy
When hydrogen moves into steel, it makes the metal become brittle, leading to catastrophic failures. This has been one of the major challenges in moving towards a greener, hydrogen-fuelled future, where steel tanks and pipelines are essential components that must be able to survive in pure hydrogen environments.

New source of space weather - too close to home
Beyond Earth's atmosphere are swirling clouds of energized particles — ions and electrons — that emanate from the sun. This “solar wind” buffets the magnetosphere, the magnetic force field that surrounds Earth. In much the same way winds and storms create weather in our atmosphere, strong gusts of solar wind penetrating the magnetosphere can generate magnetic storms with powerful electric currents that can impact our lives.

Quantum encryption realized under the sea
An international team of researchers from the Austrian Academy of Sciences and the University of Vienna established a quantum encrypted connection between Sicily and Malta via a submarine cable. The record distance of 192 kilometres was a further step in the development of a secure quantum internet.

How to verify that quantum chips are computing correctly
A new method determines whether circuits are accurately executing complex operations that classical computers can't tackle. In a step toward practical quantum computing, researchers from MIT, Google, and elsewhere have designed a system that can verify when quantum chips have accurately performed complex computations that classical computers can't.

A new approach to making airplane parts, minus the massive infrastructure
A new approach to making airplane parts, minus the massive infrastructure
Carbon nanotube film produces aerospace-grade composites with no need for huge ovens or autoclaves. A modern airplane's fuselage is made from multiple sheets of different composite materials, like so many layers in a phyllo-dough pastry. Once these layers are stacked and molded into the shape of a fuselage, the structures are wheeled into warehouse-sized ovens and autoclaves, where the layers fuse together to form a resilient, aerodynamic shell.

'Green methane' from artificial photosynthesis could recycle CO2
’Green methane’ from artificial photosynthesis could recycle CO2
A new artificial photosynthesis approach uses sunlight to turn carbon dioxide into methane, which could help make natural-gas-powered devices carbon neutral. Methane is the main component of natural gas. Photosynthesis is the process through which green plants use sunlight to make food for themselves out of carbon dioxide and water, releasing oxygen as a byproduct.
