Light-controlled microgripper bridges the gap between precision and force

For some time, researchers have used optical tweezers to manipulate tiny objects with incredible precision, using carefully controlled beams of laser light. So far, however, this technique has always come with strict limits ...

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 ...

Spray 3D concrete printing simulator boosts strength and design

Concrete 3D printing reduces both time and cost by eliminating traditional formwork, the temporary mold for casting. Yet most of today's systems rely on extrusion-based methods, which deposit material very close to a nozzle ...

'Self-driving' lab learns to grow materials on its own

When scientists make the thin metal films used in electronics, optics, and quantum technologies, they usually spend months tinkering with the temperature, composition and timing of the process, hoping to land on just the ...

Composite metal foam could lead to safer hazmat transportation

A new study finds that composite metal foam (CMF) can withstand tremendous force—enough to punch a hole in a railroad tank car—at much lower weight than solid steel. The finding raises the possibility of creating a safer ...

How AI can track hockey action from faceoff to finish

Researchers at the University of Waterloo have developed two innovative artificial intelligence (AI) systems that significantly improve how hockey games can be analyzed using video footage without the need for expensive equipment.
