Cancer may be breaking its own DNA to keep growing
Cancer cells generate DNA breaks through intense activity of genetic switches that keep growth genes active. These breaks are repeatedly repaired with occasional errors that accumulate mutations, potentially offering a therapeutic target.

NYU researchers identified molecular mechanisms that signal when plants have absorbed sufficient nitrogen. This discovery could enable development of crops requiring less fertilizer while maintaining productivity through improved soil nitrogen absorption.
How simple amber lights could make nights safer for insects
Amber lights could reduce harm to insects compared to conventional white or blue streetlights. Scientists found that switching to amber lighting addresses one threat contributing to the 40% global decline in insect species caused by artificial light pollution.
Climate change could dramatically reduce water flowing from the West's headwaters
Groundwater-fed streamflow in Western headwater watersheds has declined steadily since 1950 and could decrease 45% to 65% by century's end under current climate trends. The study, led by Northern Arizona University researchers, examined base flow that supplies many of the region's rivers.
