Phys.org / Synthetic key enzyme enables the conversion of CO₂ into formic acid

For a carbon-neutral bioeconomy, processes are needed that can efficiently capture CO2 and convert it into valuable products. Formic acid, or more specifically its salt, formate, is considered a promising candidate as it ...

Tech Xplore / How 3D printing creates stronger vehicle parts by solving aluminum's high-temperature weakness

Aluminum is prized for being lightweight and strong, but at high temperatures it loses strength. This has limited its use in engines, turbines, and other applications where parts must stay strong under high temperature conditions. ...

Medical Xpress / How an antiviral defense mechanism may lead to Alzheimer's disease

One of the main proteins that contributes to Alzheimer's disease is called phospho-tau (p-tau). When p-tau gets too many phosphate groups attached to it (a process called hyperphosphorylation), it starts to stick together ...

Medical Xpress / Hidden 'switches' in DNA reveal new insights into Alzheimer's disease

A tiny percentage of our DNA—around 2%—contains 20,000-odd genes. The remaining 98%—long known as the non-coding genome, or so-called 'junk' DNA—includes many of the "switches" that control when and how strongly genes ...

Medical Xpress / Brain on jazz: Musical improvisation moves beyond pure inspiration to dynamic reconfiguration

An international research team investigated the brains of 16 jazz pianists while they played a piece from memory, improvised based on the melody, and freely improvised based on the chord changes. The analysis of how different ...

Tech Xplore / Researchers reveal bias in a widely used measure of algorithm performance

When scientists test algorithms that sort or classify data, they often turn to a trusted tool called Normalized Mutual Information (or NMI) to measure how well an algorithm's output matches reality. But according to new research, ...
