11 remain unaccounted for after deadliest wildfire in California history

first_imgJustin Sullivan/Getty Images(PARADISE, Calif.) — Eleven people remain unaccounted for in Northern California after the deadliest wildfire in state history ravaged communities and claimed 85 lives.At one time there were a thousand names on the list of people missing or unaccounted for in Butte County, where the Camp Fire swelled to more than 153,000 acres over 18 days and destroyed nearly 14,000 homes before firefighters fully contained it on Nov. 25.The Butte County Sheriff’s Office, which released the revised list late Monday night, now says it has located 3,175 individuals who were reported missing at some point during the blaze.The death toll was also revised down to 85 from 88, after medical examiners determined several bags of human remains believed to be of separate individuals were actually the same. The remains of 43 individuals have been positively identified while 39 others have been tentatively identified, according to the sheriff’s office.Most of the people who remain unaccounted for are from the town of Paradise, a bucolic community of 27,000 people in the Sierra Nevada foothills that was virtually decimated by the Camp Fire. Many of the deaths occurred there.Melissa Schuster, a Paradise town council member, said her house was among those leveled by the Camp Fire.“Our entire five-member council is homeless,” Schuster said in a Nov. 13 interview on ABC News’ “Start Here” podcast. “All of our houses have been destroyed.”“The entire community of Paradise is a toxic wasteland right now,” she added, holding back tears.The Camp Fire ignited Nov. 8 near Pulga, a tiny community in Butte County nestled in the Plumas National Forest. That same day, the Woolsey Fire ignited near the city of Simi Valley in Southern California’s Ventura County. Both blazes exploded as strong winds fanned the flames south.In all, the pair of wildfires laid waste to a total area of nearly 400 square miles before firefighters contained the flames last month.Copyright © 2018, ABC Radio.

Observational evidence of the influence of Antarctic stratospheric ozone variability on middle atmosphere dynamics

first_imgModeling results have suggested that the circulation of the stratosphere and mesosphere in spring is strongly affected by the perturbations in heating induced by the Antarctic ozone hole. Here using both mesospheric MF radar wind observations from Rothera Antarctica (67°S, 68°W) as well as stratospheric analysis data, we present observational evidence that the stratospheric and mesospheric wind strengths are highly anti-correlated, and show their largest variability in November. We find that these changes are related to the total amount of ozone loss that occurs during the Antarctic spring ozone hole and particularly with the ozone gradients that develop between 57.5°S and 77.5°S. The results show that with increasing ozone loss during spring, winter conditions in the stratosphere and mesosphere persist longer into the summer. These results are discussed in the light of observations of the onset and duration of the Antarctic polar mesospheric cloud seasonlast_img read more

Gene network analyses support subfunctionalization hypothesis for duplicated hsp70 genes in the Antarctic clam

first_imgA computationally predicted gene regulatory network (GRN), generated from mantle-specific gene expression profiles in the Antarctic clam Laternula elliptica, was interrogated to test the regulation and interaction of duplicated inducible hsp70 paralogues. hsp70A and hsp70B were identified in the GRN with each paralogue falling into unique submodules that were linked together by a single shared second neighbour. Annotations associated with the clusters in each submodule suggested that hsp70A primarily shares regulatory relationships with genes encoding ribosomal proteins, where it may have a role in protecting the ribosome under stress. hsp70B, on the other hand, interacted with a suite of genes involved in signalling pathways, including four transcription factors, cellular response to stress and the cytoskeleton. Given the contrasting submodules and associated annotations of the two hsp70 paralogues, the GRN analysis suggests that each gene is carrying out additional separate functions, as well as being involved in the traditional chaperone heat stress response, and therefore supports the hypothesis that subfunctionalization has occurred after gene duplication. The GRN was specifically produced from experiments investigating biomineralization; however, this study shows the utility of such data for investigating multiple questions concerning gene duplications, interactions and putative functions in a non-model species.last_img read more
