Lab-engineered proteins: A promising treatment for liver disease
The research group led by CIC biomaGUNE's Ikerbasque Research Professor Aitziber L. Cortajarena has developed an innovative anti-fibrotic and anti-tumor treatment by binding a synthetic protein to gold nanoclusters (small aggregates of approximately 6 atoms of gold). Conducted in
Special relativity can warp chemical bonds – now we’ve seen it happen
An experiment with a charged molecule of bismuth and carbon reveals how effects from Albert Einstein’s special relativity reshape the standard understanding of chemical bonds
Scientists measure hidden quantum forces that could power a new generation of pharmaceutic
Scientists measure hidden quantum forces that could power a new generation of pharmaceutic
It's one thing to design a pharmaceutical drug. It's another to know if and why it actually works; not on paper or in a computer model, but inside the chaotic world of living systems, where proteins twist into shape, atoms constantly pull and push each other apart, and molecular
Metal hydride molecule trapped with laser light opens path to ultracold hydrogen
Controlling and trapping molecules, units of a substance consisting of two or more chemically bound atoms, with laser light is significantly more challenging than trapping individual atoms. This is because molecules exhibit more complex vibrational and rotational dynamics that ma
Glass cells of atoms offer a new path to smarter, cheaper sensors
More accurate navigation systems and improved wireless communications may not come from traditional electronics, but rather from atoms. Researchers at Penn State and the National Institute of Standards and Technology (NIST) have developed a new way to build tinier, smarter glass
Oxygen atoms in 15‑million‑year‑old giant eggshells reveal how plants reacted to a hotter
Some periods in Earth's history are so different from our own that they may as well belong to another planet. Many people are interested in the age of dinosaurs or the Ice Ages, but it is an intermediate world, the Miocene Epoch—a sort of "in-between" world, geologically speaking
New Horizons tracks solar wind slowdown as interstellar atoms add drag
A new Southwest Research Institute (SwRI) study based on data from NASA's New Horizons spacecraft has uncovered insights into why the solar wind gradually slows as it moves toward the edge of the solar system and the boundary with interstellar space. The study "The Gradual Slowin
Physicists demonstrate Hong–Ou–Mandel interference with more than 10 atoms
Physicists demonstrate Hong–Ou–Mandel interference with more than 10 atoms
In a new study published in Nature Physics, researchers have demonstrated the Hong–Ou–Mandel (HOM) effect with up to 12 indistinguishable neutral atoms—an effect that has been predominantly observed in photonic systems.
Quantum gravity tests may mistake ordinary spacetime for superposition
Quantum gravity tests may mistake ordinary spacetime for superposition
Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful theories of physics: quantum mechanics and gravity. Quantum mechanics explains the behavior of the microscopic world, while Einstein's theory of gravity describes

Heidelberg physicists just united two opposing quantum theories
A new quantum theory bridges two rival models of how impurities behave inside many-particle systems, resolving a problem that has challenged physicists for decades. The findings could reshape experiments on ultracold atoms, semiconductors, and other exotic forms of quantum matter
'Check your ingredients': A new blueprint for using Fermi's 'Golden Rule'
Underpinning much of modern technology, from smartphones to scanning tunneling microscopes to particle colliders, is Fermi's Golden Rule. Named for 20th-century Italian American physicist Enrico Fermi (but actually discovered by British physicist Paul Dirac), the rule is a formul
Physicists created a tiny universe where time emerged without a clock
Physicists created a tiny universe where time emerged without a clock
What if time doesn't actually exist until something changes? Scientists at the University of Birmingham created a tiny "mini universe" using 24,000 ultracold atoms and showed that the flow of time can emerge naturally from changes inside a quantum system, without relying on any e
