WASHINGTON (AP) — For much of the United States, invasive grass species are making wildfires more frequent, especially in fire-prone California, a new study finds.Twelve non-native species act as "little arsonist grasses," said study co-author Bethany Bradley, a University of Massachusetts professor of environmental conservation.Wherever the common Mediterranean grass invades, including California's southern desert, fires flare up three times more often. And cheatgrass , which covers about one-third of the Intermountain West, is a big-time fire promoter, Bradley said."I would not be surprised at all if invasive grasses are playing a role in the current fires but I don't think we can attribute to them directly," Bradley said.University of Utah fire expert Phil Dennison, who wasn't part of the study but says it makes sense, said, "In a lot of ways, California was ground zero for invasive grasses. Much of California's native perennial grassland was replaced by Mediterranean annual grasses over a century ago. This study doesn't look at invasive grasses in the areas that are burning in California, but invasive grasses are contributing to the fires there."Experts say the areas burning now in California are more shrubs and grasses than forests, despite what President Donald Trump tweeted over the weekend."This is a global problem," said University of Alberta fire expert Mike Flannigan, who wasn't part of the study but said it makes sense. "I think with climate change and human assistance we are moving to a grass world. One region they should have mentioned is Hawaii where wildfires are increasing in large part due to invasive grasses."Invasive species are spreading more because of climate change as warmer weather moves into new areas, said study lead author Emily Fusco, also of the University of Massachusetts. New England and the Mid-Atlantic are seeing new invasive and more flammable grasses, Bradley said.The study in Monday's journal Proceedings of the National Academy of Sciences looks at the connections between a dozen species of invasive grasses and fires nationwide, finding fires occur more often in places with the non-native grasses. But the study did not find a link between invasive grasses and the size of the fires.Four of these species, including cheatgrass and common Mediterranean grass, are in California. These grasses get dry and then watch out, Fusco said."When you start a fire normally you want kindling," Fusco said. "The grasses are, more or less, like kindling"If someone lights a match and throws in the middle of a forest, it is unlikely a fire will start, but throw it in a field of cheatgrass "and odds are that it's going to catch," Bradley said."We are the reason that invasive species are here. We are the reason that they get spread around," Bradley said.Flanagan noted that invasive plants that are not grasses also feed the wildfire problem.While most outside experts said the study was important, wildfire expert LeRoy Westerling at the University of California, Merced said that with wildfires the size is key so this study is less valuable because it measures frequency.While size matters in forest fires, study author Bradley said mid to small size fires are the ones "in everybody's backyard" and affect people and their buildings more. 3313

VISTA (CNS) - A Carlsbad woman who fatally shot her husband during an argument while their children watched cartoons downstairs will not have her sentence reduced in light of a recent gun law.Julie Elizabeth Harper, 45, was convicted in October 2015 of second-degree murder in the death of her husband, Jason Harper. She was sentenced to 40-years-to-life in prison.This year, the 4th District Court of Appeal found Harper's case is affected by a new law (Senate Bill 620) that took effect in 2018. The law gives judges the ability to add a "gun enhancement" to a defendant's sentence because they used a gun in the crime.RELATED: Carlsbad woman convicted of killing husband could have years removed from sentenceIn sentencing Harper in January 2016, Bowman said her testimony that her husband, a popular math teacher and volleyball coach at Carlsbad High, came at her in a rage and that she shot him accidentally was "inherently untrustworthy and not worthy of belief."Harper's attorney, Gloria Collins, argued in court documents that the gunshot Harper fired was not an "execution-style" shot but rather a single shot that entered her husband's side and "unfortunately struck him in the heart."WATCH JULIE HARPER'S EXCLUSIVE INTERVIEW WITH 10NEWS (JAN. 2016): 1278

WASHINGTON — U.S. health officials have started two new studies to test various blood thinners to try to prevent strokes, heart attacks, blood clots and other complications in COVID-19 patients.Doctors increasingly are finding blood clots throughout the bodies of many people who died from COVID-19 along with signs of damage they do to kidneys, lungs, blood vessels, the heart and other organs.National Heart, Lung and Blood Institute Director Gary Gibbons says that hospitals have been giving seriously ill patients anti-clotting drugs to try to prevent this, but “quite frankly, we didn’t know how best to treat it” in terms of which drugs or doses to use and at what stage of illness.The National Institutes of Health will coordinate a study in hospitalized patients comparing low and regular doses of the blood thinner heparin. The study will involve more than 100 sites around the world participating in a research effort with various governments, drug companies, universities and others to speed coronavirus therapies.A second study in COVID-19 patients not sick enough to need hospitalization will test various strategies against placebo pills: baby aspirin or low or regular doses of the anti-clotting drug apixaban, sold as Eliquis in the United States. The goal there is preventing blood clots or hospitalization.A third study starting later will test blood thinners for people who have recovered and no longer test positive for the coronavirus. Evidence is building that they may remain at higher risk for blood clots. 1538

VISTA, Calif. (KGTV) - Several schools in the Vista Unified School District are returning back to virtual learning for two weeks after positive COVID-19 cases were identified.The district reopened for in-person learning at normal capacity, also known as Vista Classic, on October 20th. According to the district’s website, 17 cases have been reported since October 20th.District Superintendent, Dr. Matt Doyle, said Vista Classic and Vista Virtual were designed to work together so that there is the flexibility to move back and forth.Mission Vista High School, Vista High School, Madison Middle School, Roosevelt Middle School, and Rancho Minerva Middle School are also back to Vista Virtual due to positive cases.A class of 28 students and one teacher at T.H.E. Learning Academy Elementary school is also under quarantine after one positive case was reported.Last week the school unanimously approved a plan that would close down some middle and high schools for two weeks when positive cases are reported.The closures would happen if one school has two or more positive cases at the whole time, the entire school would switch back to Vista Virtual for two weeks. If three secondary schools have one positive case each, all three will return to Vista Virtual for two weeks.“I think two is tough; that doesn’t give us a lot of confidence that it won’t close down again,” said Dolly Goulart, a parent of a Mission Vista High School student who has been back to virtual learning.“I do appreciate that they’re doing trying to get classic families back in. They gave families a choice over the summer.”Goulart said her son’s transition back to Vista Virtual went smoothly.“From my perspective, it seemed perfectly seamless. He did fine pivoting back,” said Goulart. “He’s about a week into his two-week virtual pivot.”“We meet regularly with representatives from the S.D. Health and Human Services Department to discuss our health and safety measures and make adjustments as appropriate,” said Dr. Doyle in an email to A.B.C. 10News.Doyle said in just weeks, a high volume COVID-19 testing center would open in Vista Unified.Before school reopened, the district notified parents that they couldn’t guarantee that students would be six feet apart in class.The district’s website stated, “It is important to note that while many health and safety precautions are in place for the Vista Classic learning model, all classrooms will have the normal amount of students enrolled. This means that while we will be following social distancing procedures, student seating arrangements will be less than six feet apart.”There have been mixed reactions to the reopening plan from teachers and parents; some like Goulart are happy with the plan, while others call for revisions.“Why are we allowing kids not to social distance within our classrooms?” asked Keri Avila, the Vista Teachers Association president. “When we talk about keeping businesses open, when we talk about returning to some sort of normal, this takes that all away.”Avila said, in some cases, students are in crowded classrooms without enough safety measures in place.She’s calling on the district to make changes to the current reopening plan so that schools can remain open.“We hope to work with our district to create a system to keep our schools open, not one that keeps pivoting back to virtual,” said Avila.Two positive COVID-19 cases have also been reported at Alta Vista High School, but ABC 10News has not been able to confirm if the school has closed down. 3527

VISTA, Calif. (KGTV) — A group of teachers with the Vista Unified School District rallied Thursday against the district's current reopening plan.The district's Board of Education voted late Thursday to finalize a plan to bring students and teachers back to in-person learning on Oct. 20. The group of teachers say there's now a chance they hold a vote over whether to vote of no confidence in the district's superintendent on Monday."We now face a rush to open without the protocols in place to ensure the health and safety of all stakeholders. School board members’ openly dismissive behavior toward educators and their safety concerns is hurtful and disappointing to every committed educator who calls VUSD their professional home," said Keri Avila, president of the Vista Teachers Association. "We are extremely disappointed in the lack of concern expressed at last night’s board meeting for the health and safety of students, teachers, and staff. We have scheduled and emergency executive board meeting to determine next steps."The board heard from parents and teachers on both sides. Some said they are for the full reopening, while others said bringing students back at normal capacity is too risky.Many teachers have expressed concerns that the plan just isn't safe enough during a pandemic."I think it's reckless, I think it's misguided," said Craig Parrot, an eighth-grade science teacher at Roosevelt Middle School. "There are entire schools in our district that don't have windows that open, kids are coming in without temperature checks."Parents that want to keep their students in virtual distance learning may do so.While many school districts have limited the number of students returning in-person, Vista Unified's website states, "It is important to note that while many health and safety precautions are in place for the Vista Classic learning model, all classrooms will have the normal amount of students enrolled. This means that while we will be following social distancing procedures, student seating arrangements will be less than six feet apart."Parrott said he was able to continue with distance learning because a colleague who teaches the same subject will return in-person. "The kids are too close, we have desks that are 6 inches or 12 inches apart," said Parrott.The Vista Teachers Association (VTA) sent ABC 10News pictures showing what they call a lack of spacing in between desks in some classrooms.Members of the VTA worry about the spread of COVID-19 as teachers and students return to school. Avila started a petition demanding that the Vista Unified Board of Education Trustees modify the reopening plans."We want our district to mitigate the 'Four C's', that is close, closed, crowded and continuous," said Avila. "They're going to be in crowded conditions especially if we have 38 kids in a room at one time."The district's Superintendent of Schools, Dr. Matt Doyle, sent the following statement to ABC 10News. 2958
