The leaves of Brazilian coastal forest trees can harbor hundreds of bacterial species, most of them newly described, with a different subset on each species of tree.
In open-field experiments testing how increased carbon dioxide improves crop yields, the values were half those of previous experiments conducted in enclosures.
Since the huge March 2005 earthquake, slip along the plate boundary south of Sumatra is continuing at above-average rates and causing aftershocks.
A new high-resolution neutron-scattering technique reveals the fundamental excitations in magnetic systems and shows unexpected effects at very low temperatures.
The most prominent cold period during the Holocene, 8200 years ago, spanned several hundred years and was caused by an influx of melt water into the North Atlantic.
A two-phase solvent efficiently converts fructose to a plastic precursor, providing a possible replacement for petroleum-based plastics.
A complex in which iron is in the rare +6 oxidation state and triple bonded to nitrogen is stable to 77 kelvin and can serve as a powerful oxidant upon warming.
A small molecular catalyst aligns a substrate through hydrogen bonding to oxidize a distant site selectively, a strategy commonly seen in much larger enzymes.
Although the tuberculosis bacterium incurs fitness costs when it acquires resistance to antibiotics, the more prevalent strains in humans exhibit superior compensation.
A newly described transcription factor maintains the stem cells in the hair follicle in an undifferentiated state, preventing premature differentiation.
Bacteria and archaea use multimeric enzyme complexes to covert glutamate bound to transfer RNA to glutamine before it is added to growing peptide chains.
Birds that migrate long distances to Europe from Africa are arriving earlier in the spring, perhaps as an evolutionary response to climate change.
A chromatin- and RNA-associated protein that is frequently mutated in leukemias ensures accurate recognition of splice sites by splicing factors.
Mice show empathy-like behavior, exhibiting enhanced pain sensitivity when they see a familiar mouse experience pain but not when the other mouse is a stranger.
