Magnetic ‘rusty’ nanoparticles pull estrogen out of water

Iron oxide particles adorned with “sticky” molecules trap estrogen in water, possibly limiting the hormone’s harmful effects on aquatic life.

Materials Science

This ‘thermal cloak’ keeps spaces from getting either too hot or cold

A new thermal fabric prototype could help keep cars, buildings and other spaces a comfortable temperature during heat waves while reducing CO₂ emissions.

Chemistry

Tear-resistant rubbery materials could pave the way for tougher tires

Adding easy-to-break molecular connectors surprisingly makes materials harder to tear and could one day reduce microplastic pollution from car tires.

Environment

This house was built partly from recycled diapers

Disposable diapers can replace nearly a third of the materials used in load-bearing structures, offering a potential path to more affordable housing.

Materials Science

A vegan leather made of dormant fungi can repair itself

Researchers developed a leather alternative made from dormant fungus that can be reanimated and then regrow when damaged.

Health & Medicine

A graphene “tattoo” could help hearts keep their beat

A proof-of-concept electronic heart tattoo relies on graphene to act as an ultrathin, flexible pacemaker. In rats, it treated an irregular heartbeat.

Chemistry

Here’s why some Renaissance artists egged their oil paintings

Some Renaissance artists created eggs-quisite paintings by adding yolks to oil paints, which may have helped add texture and prevent yellowing.

Animals

These transparent fish turn rainbow with white light. Now, we know why

Repeated structures in the ghost catfish’s muscles separate white light that passes through their bodies into different wavelengths.

Materials Science

These shape-shifting devices melt and re-form thanks to magnetic fields

Miniature machines made of gallium embedded with magnetic particles can switch between solid and liquid states.

Materials Science

Want a ‘Shrinky Dinks’ approach to nano-sized devices? Try hydrogels

Patterning hydrogels with a laser and then shrinking them down with chemicals offers a way to make nanoscopic structures out of many materials.

Chemistry

These chemists cracked the code to long-lasting Roman concrete

Roman concrete has stood the test of time, so scientists searched ruins to unlock the ancient recipe that could help architecture and climate change.

Animals

Here’s how polar bears might get traction on snow

Microstructures on the Arctic animals’ paws might offer extra friction that keeps them from slipping on snow, a new study reports.
