Destruction of an Earth oceans' worth of water per month in Orion Nebula
Destruction of an Earth oceans’ worth of water per month in Orion Nebula
An international team, including Western astrophysicists Els Peeters and Jan Cami , has shed light on the destruction and re-formation of a large quantity of water in a planet-forming disk located at the heart of the Orion Nebula. This discovery was made possible by an original multidisciplinary approach combining observations from the James Webb Space Telescope (JWST) and quantum physics calculations.

Yale chemists synthesize unique anticancer molecules using novel approach
Yale chemists synthesize unique anticancer molecules using novel approach
Yale researchers have developed a novel approach to synthesize a highly complex group of molecules found in marine invertebrates. Nearly 30 years ago, scientists discovered a unique class of anticancer molecules in a family of bryozoans, a phylum of marine invertebrates found in tropical waters. The chemical structures of these molecules, which consist of a dense, highly complex knot of oxidized rings and nitrogen atoms, has attracted the interest of organic chemists worldwide, who aimed to recreate these structures from scratch in the laboratory.

High resolution techniques reveal clues in 3.5 billion-year-old biomass
Research team analyses organic material from the early Earth tracing its origin and composition To learn about the first organisms on our planet, researchers have to analyse the rocks of the early Earth. These can only be found in a few places on the surface of the Earth. The Pilbara Craton in Western Australia is one of these rare sites: there are rocks there that are around 3.5 billion years old containing traces of the microorganisms that lived at that time.

Electrons become fractions of themselves in graphene
Electrons become fractions of themselves in graphene
An exotic electronic state observed by MIT physicists could enable more robust forms of quantum computing. The electron is the basic unit of electricity, as it carries a single negative charge. This is what we're taught in high school physics, and it is overwhelmingly the case in most materials in nature.

It's the spin that makes the difference
It’s the spin that makes the difference
Biomolecules such as amino acids and sugars occur in two mirror-image forms - in all living organisms, however, only one is ever found. Why this is the case is still unclear. Researchers at Empa and Forschungszentrum Jülich in Germany have now found evidence that the interplay between electric and magnetic fields could be at the origin of this phenomenon.

Quantum entanglement defies weightlessness
Quantum entanglement defies weightlessness
The ÖAW and TU Vienna were able to show during a parabolic flight: A change in gravity has no influence on quantum experiments . A team from the Austrian Academy of Sciences and the Vienna University of Technology was able to prove this during a flight with the European Space Agency: Quantum entanglement also works when the strength of gravity changes.

Spintronics: the electronics of the future could be antiferromagnetic
It is an important step forward in spintronics: the magnetic state of certain materials can be switched using surface induced strain. All our electronics are based on electrical charges being transported from one place to another. Electrons move, current flows, signals are transmitted by applying an electrical voltage.

First-ever atomic freeze-frame of liquid water
In an experiment akin to stop-motion photography, an international team of scientists has isolated the energetic movement of an electron in a sample of liquid water - while "freezing" the motion of the much larger atom it orbits. The finding reveals the immediate response of an electron when hit with an X-ray, an essential step in understanding the effects of radiation exposure on objects and people.
