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.
New 'molecular handle' uses common amino acid to build complex medicines
In a new study published in Nature Communications, a team of chemists has unveiled a radically simple way to attach a highly sought-after "molecular handle," known as the dichloromethyl group, onto complex compounds. Instead of relying on the aggressive, heavy-metal or radiation-heavy techniques of the past, the team used a common, naturally occurring amino acid called proline to gently choreograph the assembly.
Building 'green' protection for fragile enzymes
Enzymes are nature's tiny powerhouses, helping with everything from digesting food to making it quicker and safer to produce medicines, food and renewable fuels. While they can enhance chemical reactions, their fragile nature makes it difficult to use them in typical industrial processes.
New research on cellular redox reactions sheds light on the path of neurodegenerative diseases
The mechanics of the onset of cancer or neurodegenerative disorders like Alzheimer's disease or ALS remain a mystery. Scientists associate these diseases with an increase in unstable molecules called reactive oxygen species (ROS) in cells, but they don't fully know why they form or why these molecules might pose a problem. They also are beginning to determine which parts of cells are to blame for producing ROS.
