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.

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.

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.

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
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.

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
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
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.

Unexpected twist in a quantum system
Physicists at ETH Zurich have observed a surprising twist in a quantum system caused by the interplay between energy dissipation and coherent quantum dynamics. To explain it, they found a concrete analogy to mechanics. "No scientist thinks in formulae", Albert Einstein allegedly once told his colleague Leopold Infeld.

New Hubble constant measurement using cosmic lenses
New measurement of the universe's expansion rate strengthens call for new physics Using cosmic lenses an international team of astrophysicists determined the universe's expansion rate, completely independent of any previous method. The researchers' result further strengthens a troubling discrepancy between the expansion rate calculated from measurements of the local universe and the rate as predicted from background radiation of the early universe.

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.

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.

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.

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.

Unused stockpiles of nuclear waste could be more useful than we might think, according to new study
Chemists have found a new use for the waste product of nuclear power - transforming an unused stockpile into a versatile compound which could be used to create valuable commodity chemicals as well as new energy sources. Depleted uranium (DU) is a radioactive by-product from the process used to create nuclear energy.

Copper-based nanomaterials can kill cancer cells in mice
An interdisciplinary team of scientists from KU Leuven, the University of Bremen, the Leibniz Institute of Materials Engineering, and the University of Ioannina has succeeded in killing tumour cells in mice using nano-sized copper compounds together with immunotherapy. After the therapy, the cancer did not return.
