Nanoparticle food additive found in candy, gum could alter digestive cell structure and function

The ability of small intestine cells to absorb nutrients and act as a barrier to pathogens is 'significantly decreased' after chronic exposure to nanoparticles of titanium dioxide, a common food additive found in everything from chewing gum to bread.

'Lossless' metamaterial could boost efficiency of lasers and other light-based devices

Engineers have developed a material that could reduce signal losses in photonic devices. The advance has the potential to boost the efficiency of various light-based technologies including fiber optic communication systems, lasers and photovoltaics.

Printable solar cells just got a little closer

New research removes a key barrier to large-scale manufacture of low-cost, printable perovskite solar cells.

A new technique to measure the electronic structures of stacks of 2D materials

Understanding the electronic structures of 2D materials will allow scientists to find optimal materials for efficient semiconductors in nanoelectronics.

Living sensors at your fingertips

Cell-infused gloves and bandages light up when in contact with certain chemicals.

If atoms are mostly empty space, why do objects look and feel solid?

Chemist John Dalton proposed the theory that all matter and objects are made up of particles called atoms, and this is still accepted by the scientific community, almost two centuries later.

Physicists harness neglected properties of light

Technique could help increase resolution of microscopes and telescopes.
