Shake-powered capsule tests and disinfects unsafe drinking water

It is a sobering fact that in the 21st century, 1 in 4 people still lack access to safe, clean drinking water, according to the World Health Organization (WHO). The figures increase slightly during natural disasters, when ...

Heat waves: Five reasons why Victorian houses are cooler than modern buildings

More than 4 million homes were built in the U.K. during the Victorian era. Victorian homes were constructed long before the complex computer models used today to design buildings were invented. Yet these homes, built more ...

Slower heating lets atoms self‑organize into architectures that vastly boost alloy strength

Scientists have revolutionized the way metals are made by using lower and slower heating of alloys to control how atoms self-organize during material manufacturing. The discovery, published in Science by Monash University ...

Ease of use is key to exoskeleton adoption, engineers show

Wearable exoskeletons can help reduce physical strain in the workplace and protect employees from injury, but the technology has yet to achieve widespread adoption. A new study published in PLOS One by engineers at The University ...

Going up against the heat: Vertical greenery keeps cities cool

Climate change and urbanization have intensified the urban heat island (UHI) effect, where urban areas are significantly warmer than rural areas. This has, in turn, increased the frequency of extreme heat events, such as ...

Engineers create an 'electrified' house that slashes energy bills

Western engineers have amalgamated the function and force of photovoltaics (PV) technology with a heat pump and a thermal battery to create a fully electrified—and energy efficient—new house. The end game is to eliminate ...

Bubble wrap bursts enable power-free acoustic testing

Non-destructive testing allows engineers to evaluate the integrity of structures such as pipelines, tanks, bridges, and machinery without dismantling them. Conventional approaches rely on loudspeakers, lasers, or electric ...
