Clever Catalyst Assigns Jobs to Gold and Platinum for Greener Chemistry

Scientists have developed a highly efficient platinum-gold catalyst for producing hydrogen peroxide, overcoming a key flaw in previous methods. By assigning hydrogen and oxygen activation to separate sites, the new system achieves nearly 100% selectivity and doubles the product concentration compared to the initial stages of the current industrial process.

The Untapped Potential of Twisted Molecular Hoops

Scientists are unlocking the secrets of 'inherently chiral macrocycles', unique ring-shaped molecules that lose their handedness if broken. Previously too difficult to synthesise, new methods are finally allowing researchers to exploit their potential for advanced materials and catalysis.

Mapping the Brain's Shifting States in Alzheimer's Disease

New research reveals how the brain's dynamic connectivity patterns break down across the Alzheimer's spectrum. Early stages are marked by difficulty switching between neural states, while later stages see the brain becoming 'stuck' in dysfunctional patterns linked to specific genetic imbalances.

AI Predicts Cosmic Ray Effects on Electronics Millions of Times Faster

Scientists have developed a new artificial intelligence method to predict the disruptive effects of cosmic radiation on vital electronics used in space. The deep learning models forecast these 'single event effects' with exceptional accuracy but are up to a million times faster than traditional computer-aided simulations, offering a huge leap forward for semiconductor reliability testing.

Rusting the Brain: How Iron Overload May Trigger Anxiety

A study in rats reveals that excess iron in the body can accumulate in the brain, leading to increased anxiety-like behaviours. This overload triggers oxidative stress, a form of cellular damage, particularly in brain regions critical for regulating fear and anxiety.
