The New York Times Superbugs use genetic material as cloak to avoid detection A deadly class of antibiotic-resistant bacteria called carbapenem-resistant Enterobacteriaceae, carries genetic material that serves as […]
Endemic species are part of the natural heritage of a region, and their preservation for future generations should receive the same kind of priority and public understanding as historical sites, because they share a common trait: if they disappear, they will be lost forever. Of course, conservation becomes especially thorny if we are not sure […]

LiveScience Ants are organized searchers who gain […]
Nowadays there are still people that believe in destiny. However the scientific community more and more is bringing light to that subject showing that although the genetic material could program ourselves to suffer some pathologies, the day-to-day experiences are the ones that lead us towards a healthy or pathological aging. And how is that? Our […]
For many centuries, the passage of light through matter was regarded as that of a wave in a fixed medium characterized by a refractive index (n), which may depend on the frequency. This description is consistent with plenty of phenomena, including diffraction, interference, refraction, dispersion or polarization, associated to distinguished names of the history of […]
Few weeks ago, a new report by WHO reveals that antibiotic resistance is now a major threat to global public health: “ the world is headed for a post-antibiotic era ”. One of the priorities is the treatment of urinary tract infections caused by Escherichia coli strains isolated from several countries and which are resistant […]
