Sunlight's peak intensity is at a green wavelength. Here’s why it doesn’t appear that way to us.
Once a morpho butterfly wing is placed atop a thin slice of tissue, shining polarized light through it can help reveal how likely breast cancer is to spread.
Pengju Li designed a new type of pacemaker to help doctors during open-heart surgery.
The “Helmholtz resonator” concept is responsible for the sound produced by hand-clapping.
Bacteria with a gene from sea sponges can coat themselves in glass. Working as tiny, bendable lenses, they could lead to thinner cameras or sensors.
The Big Bang likely brought our universe into existence. What will mark its grand finale? Scientists blend imagination and data to make predictions.
Scientists used high pressure and heat to create plastic ice, which has qualities of both ordinary ice and liquid water.
An airplane wing’s unique shape creates air pressure differences that result in this gravity-defying force.
