Little earthquakes trembled beneath the mountain. Officials have since evacuated thousands of people to prevent what happened when Agung erupted in 1963, killing

Chemists at The Scripps Research Institute (TSRI) have now published an important demonstration of this repurposing of DNA to create new substances with

A superhydrophilic filter produced at Rice University can remove more than 90 percent of contaminants from water used in hydraulic fracturing operations. In this image, ‘produced’ water from a Marcellus shale fracturing site is at left, the retentate (carbon removed from the feed) is at center, and filtered ‘permeate’ water is at right. The hydrophilic

A new technique created by Brian Shao, Alex Bagdasarian, Stasik Popov and Hosea Nelson (from left) allows complex molecules to be assembled in fewer steps than previously possible. Credit: Penny Jennings When scientists develop the chemical formulas for new products such as fuels and medications, they often must first create molecules that haven’t previously existed.

A chemical reaction where three different molecules (e.g. H, O2, H) each participate in the breaking and forming of chemical bonds. The reaction is mediated by an ephemeral collision complex (HO2**) formed from the collision of two molecules (H, O2) which then reacts upon colliding with a third molecule (H). Data from advanced computations reveal

Cardiff Catalysis Institute researchers develop new processes with industry and promote catalysis as a sustainable 21st century technology.

Methanol is currently produced by breaking down natural gas at high temperatures into hydrogen gas and carbon monoxide before

Credit: Heribert Cypionka Achromatium oxaliferum is the largest (known) freshwater bacterium in the world. It is 30,000 times larger than its “normal” counterparts that live in water and owing to its calcite deposits it is visible to the naked eye. It has

Chury. Organic compounds,

Using a unique method involving nanocapsules made out of DNA, researchers studied a little-understood signaling process (lit up in color in the neurons above) that plays a key role in the brain.

Changes in microstructure, such as this void and fibrils created by straining a polymer sheet, appear to control how the material charges through friction.

Triboelectric charging causes toner from a photocopier or laser printer to stick
