A marvelous molecular machine

Squids, octopuses and cuttlefish are undisputed masters of deception and camouflage. Their extraordinary ability to change color, texture and shape is unrivaled, even by modern technology.

Researchers explore new chapter of physics

Interactions between light and matter are a fundamental unit of modern physics, but recently researchers have started to look beyond the standard textbook interactions.

Mimicking bug eyes could brighten reflective signs and clothes

That bright, reflective coating used on road signs, bicycles and clothing are important safety measures at night. They help drivers get to their destinations while avoiding bicyclists and pedestrians in low-light conditions. ...

Low-reflection wings make butterflies nearly invisible

The effect is known from the smart phone: Sun is reflected by the display and hardly anything can be seen. In contrast to this, the glasswing butterfly hardly reflects any light in spite of its transparent wings. As a result, ...

Minuscule bumps improve anti-reflective coating

M. S. M. Saifullah and Hemant Raut of A*STAR's Institute of Materials Research and Engineering in Singapore and their co-workers have developed a coating that matches the optical properties of the best conventional anti-reflective ...

Team makes breakthrough in solar energy research

The use of plasmonic black metals could someday provide a pathway to more efficient photovoltaics (PV) —- the use of solar panels containing photovoltaic solar cells —- to improve solar energy harvesting, according to ...

How graphene and friends could harness the Sun's energy
