The laser plasma accelerator has accelerated about half a billion electrons to 2 gigaelectronvolts over a distance of about 1 inch. It's a downsizing of a factor of approximat...
Changing ocean water temperatures and circulation patterns have profoundly affected key Northeast U.S. Continental Shelf zooplankton species in recent decades, and may be infl...
A new study has found for the first time that thirdhand smoke -- the noxious residue that clings to virtually all surfaces long after the secondhand smoke from a cigarette has cleared out -- causes significant genetic damage in human cells.
The discovery of an unexpected function for a gene that was associated to another process in the organism might be a solution in search of a problem, a clue to unsuspected connections. That is what has happened with RAP1, a gene that protects telomeres -- the ends of chromosomes -- after researchers surprisingly discovered its key role in obesity.
Scientists have discovered the survival secret to a genetic mutation that stokes leukemia cells, solving an evolutionary riddle and paving the way to a highly targeted therapy for leukemia. A new article describe how a mutated protein, called Fbxw7, behaves differently when expressed in cancer cells versus healthy cells.
Scientists have derived a series of mathematical formulas that describe how cities' properties vary in relation to their population size, and then posits a novel unified, quan...
A landmark three-dimensional digital reconstruction of a complete human brain, called the BigBrain, now for the first time shows the brain anatomy in microscopic detail -- at a spatial resolution of 20 microns, smaller than the size of one fine strand of hair -- exceeding that of existing reference brains presently in the public domain.
Scientists have observed the quantum character of light transport through the molecular machines at work in natural photosynthesis. By studying a single machine at a time, the...
Biologists quote Lewis Carroll when arguing that survival is a constant struggle to adapt and evolve. Is that true, or do groups die out because they experience a run of bad l...
One of the largest clinical trials done in infants with congenital heart diseases shows that the increasingly common practice of using the drug clopidogrel (Plavix) to reduce shunt-related blood flow issues is not effective in the dose studied.
