New models predict where E. coli strains will thrive
Bioengineers at the University of California, San Diego have used the genomic sequences of 55 E. coli strains to reconstruct the metabolic repertoire for each strain. Surprisingly, these reconstructions do an excellent job of ...
How bacteria respond so quickly to external changes
Understanding how bacteria adapt so quickly to changes in their external environment with continued high growth rates is one of the major research challenges in molecular microbiology. This is important not least for our ...
Researchers find misfolded proteins are capable of forming tree-like aggregates
A method by Rice University researchers to model the way proteins fold – and sometimes misfold – has revealed branching behavior that may have implications for Alzheimer's and other aggregation diseases.
Quality of biodiversity, not just quantity, is key
For years, scientists have believed that preserving more species, no matter which ones, is a key component to enhancing how well an ecosystem performs.
Study unlocks secret of how fruit flies choose fruit with just the right amount of ethanol
Researchers use cells to expand nature's repertoire
Using a cell's own internal machinery, Yale researchers have produced proteins not found in nature that can cause cancer in mice, they report Dec. 16 in the Proceedings of the National Academy of Sciences.
Researchers solve nano mystery
A technique which may one day be used for tumor therapy and imaging could be greatly improved thanks to new insights obtained by scientists from the University of Twente, the Erasmus MC and the TU Delft.
Research finds Neandertals, not modern humans, made first specialized bone tools in Europe
One day in 2011, undergraduate student Naomi Martisius was sorting through tiny bone remnants in the University of California, Davis, paleoanthropology lab when she stumbled across a peculiar piece.
History to blame for slow crop taming, study says
It's been about 10,000 years since our ancestors began farming, but crop domestication has taken much longer than expected – a delay caused less by genetics and more by culture and history, according to a new study co-authored ...
Explosive dynamic behaviour on Twitter and in the financial market
(Phys.org) —Over the past 10 years, social media has changed the way that people influence each other. By analysing data from the social networking service, Twitter, and stock trading in the financial market, ...
A protein that can mean life or death for cells
Each cell in an organism has a sensor that measures the health of its "internal" environment. This "alarm" is found in the endoplasmic reticulum (ER), which is able to sense cellular stress and trigger either ...
Research improves understanding of how plants protect themselves from adverse environmental conditions
(Phys.org) —Research at Iowa State University has shed new light on the genetic mechanisms that allow plants to protect themselves from environmental stress.
Chickens to chili peppers: Scientists search for the first genetic engineers
Suddenly there was a word for chili peppers. Information about archaeological remains of ancient chili peppers in Mexico along with a study of the appearance of words for chili peppers in ancient dialects ...
Study finds forest corridors help plants disperse their seeds
A forest in South Carolina, a supercomputer in Ohio and some glow-in-the-dark yarn have helped a team of field ecologists conclude that woodland corridors connecting patches of endangered plants not only ...
