Tissues consist of a heterogeneous mixture of different cell types, complicating our understanding of their biological functions and studies of disease.

How a new technique will help us mine rare-earth metals with plants
Researchers have developed a technique for detecting and measuring the concentration of many rare-earth elements in plants, without destroying the plant. The technique can be used to optimize "plant mining" efforts, in which plants take up and concentrate these critical materials so that they can be harvested for practical use. The paper is published in the journal Plant Direct.
Marine sponge bacterium enzyme reveals a two-part route to make terpenoids
The molecular structure of an enzyme from a marine bacterium with potential industrial uses has been determined by RIKEN researchers. The insights they have gained could help make a range of useful compounds through genetic modification. The research is published in the journal Chemical Science.
How a hidden receptor switch could open new paths for cancer and neurological treatments
A research team at Leipzig University has identified a mechanism in adhesion G protein-coupled receptors (adhesion GPCRs), a specific group of membrane receptors. This mechanism is essential for the activity of many of these receptors. The study, published in Nature Communications, shows that a specific interaction between two amino acids is indispensable for the self-cleavage of these receptors. This insight could pave the way for new therapies for cancer, neurological disorders and inflammatory diseases associated with malfunctioning adhesion GPCRs.
Scientists develop 'light switch' for the love hormone
Researchers have developed a molecular "light switch" for the so-called love hormone oxytocin, offering new insights into how social behavior, partnership bonding, emotions, and mental health are wired in the brain. Professor Markus Muttenthaler from UQ's Institute for Molecular Bioscience said a light used at a specific wavelength releases neuropeptides, enabling researchers to observe their effects on individual synapses, neurons, and neuronal circuits.
Discarded wood helps produce hydrogen peroxide with more than 95% selectivity
Hydrogen peroxide, a versatile chemical used in a wide range of applications—from medical disinfectants to semiconductor manufacturing and water treatment—is an essential substance with global annual production exceeding tens of millions of tons. However, its production still relies on large-scale, energy-intensive facilities, and its transportation and storage involve high costs and significant safety management challenges.
