Combustion engines, the engines in gas-powered cars, only use a quarter of the fuel’s potential energy while the rest is lost as heat through exhaust.

Now, a study published in ACS Applied Materials & Interfaces demonstrates how to convert exhaust heat into electricity...

Various clean energy technologies have been developed to meet the rapidly intensifying energy demand and dwindling fossil fuel reserves. However, many of these technologies are hindered by low efficiency and high costs.

Hydrovoltaic (HV) mechanisms, in which electricity is generated by the direct interaction of nanostructured materials and water molecules, have recently emerged as promising, cost-efficient alternatives. HV systems show particular promise for powering electrical sensors, including fire sensors.

Traditional fire sensors rely on batteries to operate during power outages, but these batteries can explode during fires...

Xenon gas inhalation reduced neurodegeneration and boosted protection in preclinical models of Alzheimer’s disease. Most treatments being pursued today to protect against Alzheimer’s disease focus on amyloid plaques and tau tangles that accumulate in the brain, but new research from Mass General Brigham and Washington University School of Medicine in St. Louis points to a novel — and noble — approach: using Xenon gas...

Molecular clues about the neurotoxic effects of PFAS. A new study has identified 11 genes that may hold the key to understanding the brain’s response to these pervasive chemicals commonly found in everyday items.

Per- and polyfluorinated alkyl substances (PFAS) earn their “forever chemical” moniker by persisting in water, soil and even the human brain.

This unique ability to cross the blood-brain barrier and accumulate in brain tissue makes PFAS particularly concerning, but t...
