Light-activated control of protein localization in mammalian cells. The protein is initially in the cytoplasm and excluded from the nucleus of the cell (blue area in the middle each cell). Upon illumination, the part of the protein that prevents it from entering the nucleus is cleaved off and the protein is now able to enter

Chemical signals (shown in purple and orange) switch an artificial receptor (shown as a grey helix) on and off. Credit: University of Bristol Researchers from the University of Bristol have found a way to mimic the way cells in living organisms ‘talk’ to the world around them by creating a world-first synthetic receptor which can

The 3-D view of the nuclear lamina shows a section of the architecture of the delicate meshwork made of lamin filaments (filament rod in dark grey and its globular domains in red) beneath the cell nuclear membrane (transparent grey) and the nuclear pore complexes (blue).

Reservoir for heavy hydrogen: Molecules of the heavy hydrogen isotopes deuterium and tritium preferentially bind to copper atoms in a metal-organic framework compound. The metal atoms are therefore symbolically represented as shells in this image. Credit: University Leipzig / Thomas Häse Deuterium and tritium are substances with a future – but they are rare. The

An illustrative summary of the developed organic luminescent material. Credit: Youhei Takeda Mechanochromic luminescent (MCL) materials change their color in response to a change in their environment, like pressure and temperature. To date, most MCL materials only change between two colors, limiting their applications. The international research team comprising of chemists at Osaka University and

Catalytic conversion of biomass-derived chemicals to renewable polymers occurs in laboratory stirred-tank reactors. Credit: University of Minnesota A team of researchers, led by the University of Minnesota, has invented a new technology to produce automobile tires from trees and grasses in a process that could shift the tire production industry toward using renewable resources found

This reusable, multi-layered and microfluidic device incorporates a porous growth substrate, with a physiological fluid flow, and the passive filtration of the capillaries around the end of a kidney, called the glomerulus, where waste is filtered from blood.

The new kind of dynamic material could be revolutionary, similar to other materials created

Crystal structure of Na2He, resembling a three-dimensional checkerboard. The purple spheres represent sodium atoms, which are inside the green cubes that represent helium atoms. The red regions inside voids of the structure show areas where localized electron pairs reside.Illustration is provided courtesy of Artem R. Oganov. Although helium is the second most-abundant element (after hydrogen)

A schematic illustration of a microbial fuel cell using a paper electrode coated with carbon paste. Credit: Michael Osadciw/University of Rochester The concept behind microbial fuel cells, which rely on bacteria to generate an electrical current, is more than a century old. But turning that concept into a usable tool has been a long process.
