The threads of an evolutionary mystery that dates to the birth of molecular biology are beginning to unravel, thanks to a new investigation by computational bioengineers at Rice University and the University of Texas MD Anderson ...
As organisms develop, their internal organs arrange in a consistent asymmetrical pattern--heart and stomach to the left, liver and appendix to the right. But how does this happen?
Rapidly dividing cancer cells are skilled at patching up damage that would stop normal cells in their tracks, including wear and tear of telomeres, the protective caps at the end of each chromosome.
Researchers have built a map that shows how thousands of proteins in a fruit fly cell communicate with each other . This is the largest and most detailed protein interaction map of a multicellular organism, demonstrating ...
(PhysOrg.com) -- A summer research expedition organized by scientists at Scripps Institution of Oceanography at UC San Diego has led to the identification of gigantic amoebas at one of the deepest locations on Earth.
Researchers from Johns Hopkins have quantified the number of possible decisions that an individual cell can make after receiving a cue from its environment, and surprisingly, it's only two.
For cooperation to persist in the often violently competitive realm of bacteria, cheaters must be kept in line.
(PhysOrg.com) -- Cells at the tip of the slime mold's fruiting body organize into an epithelial layer and secrete proteins as do some animals cells.
(PhysOrg.com) -- In a new study, scientists at the University of Maryland and the Institut Pasteur show that bacteria evolve new abilities, such as antibiotic resistance, predominantly by acquiring genes from other bacteria.
