SEATTLE (AP) — U.S. scientists said Friday they will investigate why an unusual number of gray whales are washing up dead on West Coast beaches.About 70 whales have been found dead so far this year on the coasts of California, Oregon, Washington and Alaska, the most since 2000. About five more have been discovered on British Columbia beaches. That's a very small fraction of the total number of whales believed to have died, because most simply sink and others wash up in such remote areas they're not recorded.NOAA Fisheries on Friday declared the die-off an "unusual mortality event," providing additional resources to respond to the deaths and triggering the investigation."Many of the whales have been skinny and malnourished, and that suggests they may not have gotten enough to eat during their last feeding season in the Arctic," agency spokesman Michael Milstein told reporters during a conference call.The eastern North Pacific gray whales were removed from the endangered species list in 1994, after recovering from the whaling era.The population has grown significantly in the last decade and is now estimated at 27,000 — the highest since surveys began in 1967. That has raised questions about whether their population has reached the limit of what the environment can sustain. Another theory suggests that the loss of Arctic sea ice due to global warming is a culprit.The whales spend their summers feeding in the Arctic before migrating 10,000 miles (16,000 km) to winter off Mexico. Though they eat all along their route, they are typically thinning by the time they return north along the West Coast each spring.They eat many things, but especially amphipods, tiny shrimp-like creatures that live in sediment on the ocean floor in the Arctic. For many years, researchers noted that fewer calves tended to be born following years when the ice in the Chukchi Sea, north of the Bering Strait between Alaska and Russia, was late to melt. The whales had less time to feast because they couldn't access the feeding area, and thus had less blubber to sustain them on their next migration.Last year, though, the Artic was unusually warm. The whales weren't blocked from the feeding area, and yet are still struggling this year. That has scientists wondering if the loss of sea ice has led to a loss of algae that feed the amphipods. Surveys show the amphipod beds moving farther north, said Sue Moore, a biological oceanographer at the University of Washington."The sea ice has been changing very quickly over the last decade or so," she said. "The whales may have to shift to other prey, such as krill or other things they eat."In an average year, about 35 whales wash up in the U.S.In 2000, more than 100 did, prompting NOAA to declare an "unusual mortality event" then as well. The resulting investigation failed to identify a cause. The die-off followed strong changes in ocean conditions in the mid-1990s, suggesting that warmer water patterns affected the availability of prey, but scientists were often unable to perform necropsies, Moore said."It's sometimes very difficult to get to these whales in a timely fashion," she said. "You can't always get the kind of samples you would need for diagnostic reasons."Since then, researchers have built up an improved network of volunteers and have better educated the public to help report and respond to whale deaths, said Deborah Fauquier, veterinary medical officer at NOAA's Office of Protected Resources. This time around, scientists have been able to perform necropsies on 20 of the whales, she said.John Calambokidis, a research biologist with the Cascadia Research Collective, noted that as the whales search farther afield for food, they've entered areas where they're not normally seen so often, including San Francisco Bay and Puget Sound. That puts them at higher risk of being struck by ships or entangled in fishing gear.Four of the 10 gray whales found dead near San Francisco this year were struck by ships, and a number of shipping companies have slowed their vessels in the area to avoid collisions. 4086

SANTEE, Calif. (KGTV) - A Santee family believes their loved one was among the four people killed by mysterious blue pills last week. “That’s the biggest thing is, I’m pissed somebody is out there doing this,” said Dan Steele, the stepfather of Casey Force. Force, 39, said goodbye to his mother as she left for work Wednesday night. The next morning, Force’s three sons woke up and found him dead in his bed. Steele said the family hasn’t received an official cause of death, but deputies told him blue pills were found in the bedroom. RELATED: Mysterious pills sold on the street linked to several deaths in San Diego CountyInvestigators say the mysterious pills, linked to four recent deaths in San Diego County, are counterfeit oxycodone, likely laced with fentanyl. Force was nine months sober from his alcohol addiction and appeared to be succeeding as a painter. Steele said he didn’t know Force was taking painkillers or where they came from. “It’s tough; it makes me mad that such a thing is out there,” said Steele. “They need to be off the streets, anybody pushing drugs needs to be off the streets.” RELATED: Encinitas mother believes her son died of mysterious blue pillsSteele shared a message for other families in the wake of the drug deaths. “Don't be afraid to talk about it; say something, bring some awareness,” Steele said. “Put it out there, nothing you get off the street is reliable. Always thinking about it as taking a death pill.” The Sheriff’s Department has yet to make any arrests in the blue pill investigation. Anyone with information is asked to call Crime Stoppers.A fundraising campaign has been set up to help the family with expenses. 1679

Scientists are tracking an object heading toward earth that could enter the planet’s orbit, and they are not entirely sure what it is.The object, named Asteroid 2020 SO, is believed to be man made and not a piece of moon or other planetary debris."I suspect this newly discovered object 2020 SO to be an old rocket booster because it is following an orbit about the Sun that is extremely similar to Earth's, nearly circular, in the same plane, and only slightly farther away (than) the Sun at its farthest point," Dr. Paul Chodas, the director of NASA’s Center for Near Earth Object Studies, told CNN."That's precisely the kind of orbit that a rocket stage separated from a lunar mission would follow, once it passes by the Moon and escapes into orbit about the Sun. It's unlikely that an asteroid could have evolved into an orbit like this, but not impossible,” Dr. Chodas continued.Other publications believe the object could be from Surveyor 2, which was launched in September 1966.Scientists are estimating 2020 SO will enter earth’s orbit in November 2020, then pass by earth at a distance of roughly 30,000 miles in December, before heading back out to space in early 2021.For perspective, commercial planes fly at an altitude of about 7 miles on average.There is no danger to earth posed by 2020 SO, but its slow speed and relatively close pass-by, means scientists can study it. It’s also a reminder that objects sent into space remain in space. 1461

  

School districts across the country are being tasked with opening their campuses safely. Social distancing is a big part of that, but limited spacing at schools and a lack of available teachers is making that difficult."We are also having our students wear masks, as well, to keep our students and our staff healthy. I worked with superintendents across the state to compare plans and what they're following. Most of us are trying to keep that three foot distancing facing forward when possible and six foot distancing when we can, as well," said Jonathon Cooper, the Superintendent of Mason City Schools in Ohio. Cooper said each level of his district's plan aligns with the levels of coronavirus cases in their community. For example, if COVID-19 levels rise to a certain level, the district will move to having students in class only a couple days a week."The way that it is structured, is it’s every other day and so it creates consistency for our families and it allows our teachers to have 50% of the class in person that they can concentrate on, get them set up for the next day while the other 50% of their class comes in. It allows them to spread out in their classroom," Cooper explained.Many public school districts say they're dealing with reduced budgets, so hiring new teachers to ensure smaller class sizes is not a possibility. Plus, a lot of educators say even if they could hire teachers right now, there are not enough qualified candidates."This COVID-19 health crisis has really exposed inequities in many of our public institutions and definitely in our education system and it shows the reason why we don’t have that pool of new up and coming educators," said Manuel Bonilla, the president of the Fresno Teachers Association in California."We see it in all the documents from federal to state to local, that physical distancing is one of the things that needs to take place and we just don’t have the manpower to do so with teacher shortage," Bonilla said. He adds that many of the roughly 4,000 teachers in his city don't even feel comfortable taking on face-to-face learning in the classroom this fall. "When you just take a look at the CDC guidelines, the state guidelines and the local guidelines as to what you need in order to return safely in a classroom, physical setting, we know that by the start of school date we just can't do that," Bonilla said.And if teachers get sick, it may be hard or unsafe to find replacements. Bonilla is concerned with the availability and willingness of substitute teachers during this time. "See and that’s one of the points in regards to substitute teachers and the physical reopening of schools. When you take a look at the qualifications of quarantine and the subs moving from place to place and it's by the nature of their position they might be in different areas or causing that unsafe atmosphere just because there will be different contact points," says Bonilla.Districts are also worried that any lack of protections for teachers could further impact a teacher shortage.Back in Ohio, Cooper said, "We're also losing funding really quickly from our state. We’ve lost .2 million in the last four months. So when you’re losing money, you’re doing these amazingly new strategies to keep everybody safe and things we’ve never done before so we’re writing the script as we go,"The superintendent adds that many education administrators nationwide are leaning on each other now more than ever to make the right decisions when it comes to reopening schools this fall. 3541

  

SANTA CRUZ COUNTY, Calif. -- With wildfires burning across the West Coast and coronavirus concerns impacting communities, emergency evacuation shelters in California are facing crisis and chaos.In Santa Cruz County, leaders say local fires have displaced about one in every five residents.That includes Anthony Koppe, who lost his house in Boulder Creek during the CZU fire.“I don’t want to dwell on it too much. you know,” he said. “It’s happened and we got to move on.”Koppe and many others from California’s Central Coast are now seeking help at a local recovery resource center where new safety measures have been added to combat COVID-19.“If somebody has something, instead of passing it on, you can catch it at the door,” he said.Just to get in those doors, people have to pass a pretty strict health screening, like filling out an extensive questionnaire and getting your temperature taken with a new touchless thermometer.“It’s impacted everything,” Rosemary Anderson, emergency services manager for the County of Santa Cruz, said about how COVID-19 has changed how emergency evacuations shelters are operating.Gone are the days of hundreds of cots stuffed in an auditorium. Now, places like Kaiser Permanente Arena, which normally holds 25,000 people, has a maximum capacity of 68.“Everything was measured out so each of the tables and the resources are all 6 feet apart and people can interact from a distance where its COVID safe,” Anderson said.COVID-19 concerns have also impacted other disaster relief organizations.“Where we’d normally have 500 people in a gym, now we’re only doing about 50,” said Tony Briggs of the American Red Cross.Briggs says the coronavirus has forced his teams to change how they help people cope with disaster during this pandemic.“Now, with COVID, we can do all the listening, but you can’t do the contact,” he said. “And for some people, that hug is a really, really big deal.”Even with the added attention to detail, leaders in Santa Cruz are expecting coronavirus transmission rates to increase because more people are coming in contact at these resource centers.“If something is wrong with somebody, I definitely don’t want to catch it or my lady or my son,” Koppe said.While people like Koppe may have lost their homes, these new safety measures haven’t let them lose hope“It definitely gives me peace of mind,” he said. 2375
