The technology addresses critical safety concerns in high-pressure occupations where mental fatigue significantly contributes to accidents. Recent incidents—such as a January collision at Reagan National Airport attributed to understaffed air traffic control operations—underscore the urgent need for objective mental workload assessment tools.

Traditional EEG monitoring relies on bulky caps with multiple electrodes and conductive gels, which can be unstable due to variations in head shape. A new approach using disposable electronic tattoos overcomes these limitations with custom-fitted adhesive sensors designed to conform to individual facial geometry.

Detecting airborne hazardous chemicals has long posed a challenge due to their dilute concentrations and high mobility. Yet, effective monitoring of these substances is essential for protecting public health and the environment. A newly developed device, known as ABLE, offers a promising solution by making airborne hazard collection and detection both more efficient and accessible.

Developed by researchers from the University of Notre Dame and the University of Chicago, ABLE is a compact device measuring just four by eight inches. Despite its small size and low cost—under $200—it has demonstrated powerful capabilities in capturing and analyzing airborne contaminants.

Hydrogen is often touted as the fuel of the future, offering clean energy with water as the only byproduct. However, most current hydrogen production methods are expensive and emit large amounts of carbon dioxide—undermining its promise as a truly green fuel. Researchers at MIT may have found a way to change that, using a simple reaction between recycled aluminum and seawater to produce hydrogen cleanly and efficiently.

The technique, known as the aluminum-water reaction (AWR), utilizes scrap aluminum, waste heat, and a recyclable metal alloy to generate hydrogen with significantly lower emissions. A full life cycle analysis of this process revealed it produces just 1.45 kilograms of CO₂ per kilogram of hydrogen, compared to the 11 kilograms of CO₂ emitted by conventional fossil-fuel-based methods.

Aircela, a clean energy startup led by CEO and co-founder Eric Dahlgren, has developed a compact machine capable of producing gasoline using only air, water, and renewable electricity. Built on direct air capture research pioneered by physicist Klaus Lackner, the system turns carbon dioxide from the atmosphere into engine-ready fuel, without relying on fossil resources.

At the heart of Aircela’s process is a carbon capture system that uses a water-based solution containing potassium hydroxide to absorb CO₂ directly from the air. As ambient air flows through a specially designed chamber, the liquid sorbent extracts carbon dioxide, which is then regenerated and reused, making the process both efficient and sustainable.

A new artificial intelligence model developed by researchers at Charité – Universitätsmedizin Berlin could transform how brain tumors are diagnosed, especially in cases where traditional biopsies are risky or impossible. The innovation comes in response to complex cases like that of a patient who first sought medical help for double vision. An MRI revealed a tumor located in a part of the brain that made surgical biopsy highly dangerous.

Confronted with such challenges, the team of researchers turned to an alternative approach. Instead of relying on tissue samples, they developed a method that uses an AI model to analyze the epigenetic fingerprint of tumors—chemical modifications in the genetic material that act like cellular memory and regulate gene activity. These fingerprints can be collected from body fluids such as cerebrospinal fluid, making the process minimally invasive.

In a world increasingly burdened by both plastic waste and carbon emissions, scientists at the University of Edinburgh have developed a breakthrough method that could change how we produce everyday medicines. Instead of relying on crude oil and energy-intensive chemical processes, researchers have found a way to turn plastic waste into paracetamol (also known as acetaminophen)—using nothing more than genetically engineered bacteria.

Traditionally, paracetamol is manufactured from fossil fuel-derived compounds. The production process burns through vast amounts of crude oil, contributing heavily to global carbon emissions. Each year, thousands of tons of fossil fuels are consumed to manufacture medicines like paracetamol, generating significant environmental costs.
