Researchers are investigating medicines that selectively kill decrepit cells to promote healthy aging

Pure Structural Color is made of several extremely thin sheets of non-conductive material. These layers are stacked together and imprinted, or stamped, with a nano-scale pattern of rods with curved ends. This pattern scatters light into colors that are visible from all directions, and different hues can be produced by changing the dimensions of the pattern.

It’s shocking how many everyday inventions we use without acknowledging the inventors that helped bring them to us.

Five Women Inventors You Didn't Learn About in History Class

These innovators pioneered word processing, launched Americans into space and more

Dried cochineal insects — shown here in the center of the photo — can be processed to create several natural dyes such as carmine and cochineal extract. These products get their red hue from carminic acid, a chemical found within the insect.

Scientists Are Making Cochineal, a Red Dye From Bugs, in the Lab

Used to color foods and cosmetics, carminic acid is traditionally 'farmed' from an insect. But researchers are moving to engineer it in microbes

After Alice Ball's death in 1916 at age 24, a white man took credit for her research

Scholars say that Afrocentric notions of invention have often emphasized serving the needs of the community, social justice and artistic self-expression, such as the unpatented innovations of DJ Grandmaster Flash, who reimagined turntables and mixers as musical instruments and developed techniques like “scratching” that defined rap and hip- hop music. .

Tearing Down the Barriers for Black Inventors Begins With Honoring Their Historic Breakthroughs

Smithsonian’s Eric S. Hintz, a historian of invention, details how scholars are envisioning a more inclusive ecosystem for the innovators of tomorrow

A new way of recycling has grabbed the attention of some of the world’s largest consumer goods companies, including L’Oréal, Nestlé, and PepsiCo, who collaborated with startup company Carbios to produce proof-of-concept bottles.

The Future of Recycling May Be in Microbes

An enzyme-based recycling technology is poised to go commercial, but questions about cost and scalability linger

The science behind bubbles in champagne is an active field of research. Here, a red spotlight highlights bubbles growing at the bottom of a goblet, where they stick thanks to surface tension.
