| Under the northern lights: Mesospheric ozone layer depletion explained Posted: 21 Aug 2021 08:38 AM PDT The same phenomenon that causes aurorae -- the magical curtains of green light often visible from the polar regions of the Earth -- causes mesospheric ozone layer depletion, which could have significance for global climate change. Now, a group of scientists has observed, analyzed, and provided greater insight into this phenomenon. |
| New breakthrough in research into old insect exoskeletons Posted: 20 Aug 2021 08:10 AM PDT Researchers have isolated genetic material from exuviae (discarded exoskeletons) left after insects like cicadas molt. The researchers tested five different methods of amplifying the DNA sample by PCR, and were able to isolate nuclear DNA of good enough quality for repetitive loci known as microsatellites to be genotyped. This work is a significant contribution to insect sciences because these methods can be used for any insect species that molts. |
| Dynamic photosynthesis model simulates 10-20 percent yield increase Posted: 19 Aug 2021 11:27 AM PDT A team has developed a model that treats photosynthesis as a dynamic process rather than an activity that either is or is not happening. This allowed the group to examine the impacts of the many fluctuations in light that crop leaves experience due to intermittent clouds, overlying leaves, and the sun's daily passage across the sky. |
| Hydraulic fracturing can impact surface water quality, study suggests Posted: 19 Aug 2021 11:27 AM PDT The estimated impact on water quality is more pronounced during the period when wells generate large amounts of flowback and produced water, and where water monitors are closest to wells. More data is needed to better understand the full extent of the impact. |
