Efficient buildings could save thousands of lives in U.S. every year, shows Yale study

Buildings in the U.S. are responsible for 40% of the country’s total energy consumption. By improving the energy efficiency of new and existing buildings, the...

Scientists set new record with bifacial solar cells

Scientists at The Australian National University (ANU) have produced a more efficient type of solar cell, using laser processing and setting a new world...

Scientists create self-healing 3D building blocks

Scientists have created 3D building blocks that can heal themselves in response to damage. The engineered living materials (ELMs) exploit biology's ability to heal and...

High-speed camera captures a water jet’s splashy impact as it pierces a droplet

Squirting a jet of water through a drop of liquid may sound like idle fun, but if done precisely, and understood thoroughly, the splashy...

Tandem solar cells could help convert more energy from sun

Many countries around the world are committed to reducing emissions or reaching net-zero emissions to meet the United Nations' climate goals of maintaining temperature...

Woven nanotube fibers could turn heat into power, shows study

Invisibly small carbon nanotubes aligned as fibers and sewn into fabrics become a thermoelectric generator that can turn heat from the sun or other...

Polymer helps make tougher recyclable thermoplastics

To synthesize plastic, small monomer molecules need to be strung together like beads in a necklace, creating long polymer chains. However, not all plastics –...

This material inspired by chain mail could transforms from flexible to rigid on command

Engineers at Caltech and JPL have developed a material inspired by chain mail that can transform from a foldable, fluid-like state into specific solid...

Want to swim like a fish? Engineers uncover the secrets of fish fins

Peer into any fishbowl, and you'll see that pet goldfish and guppies have nimble fins. With a few flicks of these appendages, aquarium swimmers can...

Scientists find new way to quadruple microbatteries’ energy density

Weighing about as much as two grains of rice but with the energy density of a much larger, heavier battery, the researchers’ packing-free design...
