AI-powered data analysis tools have the potential to significantly improve the quality of scientific publications. A new study by Professor Mathias Christmann, a chemistry professor at Freie Universität Berlin, has uncovered shortcomings in chemical publications.

Using a Python script developed with the help of modern AI language models, Christmann analyzed more than 3,000 scientific papers published in Organic Letters over the past two years. The analysis revealed that only 40% of the chemical research papers contained error-free mass measurements. The AI-based data analysis tool used for this purpose could be created without any prior programming knowledge.

“The results demonstrate how powerful AI-powered tools can be in everyday research. They not only make complex analyses accessible but also improve the reliability of scientific data,” explains Christmann.

As humans age, their brain function can progressively decline and they become more vulnerable to developing neurodegenerative diseases, such as dementia. Dementia and other progressive neurological conditions can significantly impair their memory, thinking skills and daily functioning, significantly reducing their quality of life.

Many psychology and neurological studies have tried to identify biological markers and lifestyle factors that can contribute to the development of dementia. Yet the contribution of psychological characteristics (e.g., traits, emotional well-being and cognitive resilience) to a decline in mental functions remains poorly understood.

Researchers at University of Barcelona, University College London (UCL), Normandy University and other institutes across Europe recently set out to fill this gap in the literature, by trying to determine whether specific sets of psychological characteristics relate to brain health in middle and late adulthood. Their paper, published in Nature Mental Health, identified three key psychological profiles that were linked to different cognitive and mental health trajectories after middle-age.

A new tapered flow channel design for electrodes improves the efficiency of battery-based seawater desalination, potentially reducing energy use compared to reverse osmosis. This breakthrough may benefit other electrochemical devices, but manufacturing challenges need to be addressed.

Engineers have developed a solution to eliminate fluid flow “dead zones” in electrodes used for battery-based seawater desalination. This breakthrough involves a physics-driven tapered flow channel design within the electrodes, enabling faster and more efficient fluid movement. This design has the potential to consume less energy compared to conventional reverse osmosis techniques.

A team of researchers report colloidal quantum dots (QDs) offer a unique platform for exploring quantum effects.

Researchers developed a durable, bioinspired ZIF-67 MOF membrane that efficiently separates propylene from propane, offering high performance, long-term stability, and industrial scalability.

Polymer-grade propylene (99.5%) is a vital raw material in the chemical industry. Its production inevitably generates propane as a byproduct in the product stream. A critical step in producing polymer-grade propylene is the separation of propylene from propane—a challenging and energy-intensive process due to the molecules’ nearly identical physical and chemical properties.

Molecular sieve membranes offer an energy-efficient and effective solution for this separation. Metal-organic frameworks (MOFs.

Bright, twisted light can be produced with technology similar to an Edison light bulb, researchers at the University of Michigan have shown. The finding adds nuance to fundamental physics while offering a new avenue for robotic vision systems and other applications for light that traces out a helix in space.

“It’s hard to generate enough brightness when producing twisted light with traditional ways like electron or photon luminescence,” said Jun Lu, an adjunct research investigator in chemical engineering at U-M and first author of the study on the cover of this week’s Science.

“We gradually noticed that we actually have a very old way to generate these photons—not relying on photon and electron excitations, but like the bulb Edison developed.”

Scientists have built an artificial motor capable of mimicking the natural mechanisms that power life. Just like the proteins in our muscles, which convert chemical energy into power to allow us to perform daily tasks, these tiny rotary motors use chemical energy to generate force, store energy, and perform tasks in a similar way.

The finding, from The University of Manchester and the University of Strasbourg and published in the journal Nature, provides new insights into the fundamental processes that drive life at the molecular level and could open doors for applications in medicine, energy storage, and nanotechnology.

“Biology uses chemically powered molecular machines for every biological process, such as transporting chemicals around the cell, information processing or reproduction. By replicating nature at the nanoscale level, we can design entirely new materials with highly specific functions that don’t exist in the natural world. Building this outside of nature also gives us greater simplicity and control over its functions and uses,” said Professor David Leigh, lead researcher from The University of Manchester.
