Atom by Atom, Bond by Bond, a Chemical Reaction Caught in the Act
Berkeley Lab scientists have produced remarkable images of carbon atoms and the bonds among them. Resembling glowing textbook diagrams, hydrocarbon molecules are shown in high resolution for the first time before and after the breaking, rearrangement of atoms, and reforming of bonds during a complex chemical reaction.
Reading the Human Genome
Berkeley Lab researchers have achieved a major advance in understanding how genetic information is transcribed from DNA to RNA by providing the first step-by-step look at the biomolecular machinery that reads the human genome.
What Kind of Iron is in the Southern Ocean?
The Southern Ocean, circling the Earth between Antarctica and the southernmost regions of Africa, South America, and Australia, is notorious for its High Nutrient, Low Chlorophyl zones, areas otherwise rich in nutrients but poor in essential iron. Sea life is less abundant in these regions because the growth of phytoplankton, the marine plants that form [...]
First Direct Observation of Oriented Attachment in Nanocrystal Growth
Berkeley Lab researchers have reported the first direct observation of nanoparticles undergoing oriented attachment, the critical step in biomineralization and the growth of nanocrystals. A better understanding of oriented attachment in nanoparticles is a key to synthesizing new materials with remarkable structural properties.
