Physicists from Heinrich Heine University Düsseldorf (HHU) have examined a fundamental property of quantum mechanics in collaboration with the German Aerospace Center (DLR). In the scientific journal Physical Review Letters, they show that this theory does not necessarily need to be formulated with imaginary numbers – real numbers can in fact also be used.

Quantum mechanics is the branch of physics that explains how matter and energy behave at the atomic and subatomic scale. Developed in the early 1900s by pioneers including Max Planck, Niels Bohr, Werner Heisenberg, and Erwin Schrödinger, it has become one of the most successful scientific theories ever created.

The theory accurately describes a wide range of microscopic phenomena...

Eliminating sugar from your diet may be more detrimental than previously thought, according to an animal study presented at ENDO 2026, the Endocrine Society’s annual meeting in Chicago.

“Completely removing sucrose from a low-fat diet may unexpectedly disrupt gut health and promote inflammation and metabolic dysfunction, highlighting that balanced nutrition is more important than simply eliminating sugar,” said Rasheed Ahmad, Ph.D., principal scientist and head of the Immunology & Microbiology Department at the Dasman Diabetes Institute in Kuwait City, Kuwait. The institute was founded by Kuwait Foundation for the Advancement of Sciences.

Researchers investigated the effects of a sucrose-free low-fat diet compared with a sucrose-containing low-fat control diet in two groups of m...

A joint research team has experimentally observed ballistic transport in single-crystalline copper thin films, demonstrating that ballistic transport is achievable in an industry-standard metal at interconnect-relevant dimensions. The study, titled “Ballistic transport in nanodevices based on single-crystalline Cu thin films,” was published in Nature Communications.

For millions of people living with osteoarthritis, daily life can involve a frustrating cycle of pain and stiffness. While current treatments like over-the-counter medications or steroid injections can temporarily dull the ache, they do not stop the joint from deteriorating. A Yale study published in the journal Bioactive Materials found that the medication lacosamide acts as a highly effective, dual-purpose treatment that relieves joint pain and reverses cartilage damage in osteoarthritis, especially when a specialized hydrogel delivers the drug directly into the joint.
