Saturday is National Prescription Drug Take-Back Day, so multiple collection sites have been set up across the country that will allow people to drop off unneeded or expired medications.According to the 2018 National Survey on Drug Use and Health, 9.9 million Americans misused controlled prescription drugs.The DEA says National Prescription Drug Take-Back Day "addresses a crucial public safety and public health issue" and will take place from 10 a.m. to 2 p.m. in local time zones.Walmart and Sam's Club announced on Wednesday that they'd be hosting an in-person medication disposal events at select stores across the U.S.Click here to find a collection site near you. Last year, the DEA says 882,919 pounds of unwanted prescriptions were collected. 761

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

SEATTLE (AP) — Since September, six sea lions have died from gunshot wounds in central Puget Sound and Kitsap County, Washington.The Seattle Times reports that another seven are suspected to have died from "acute trauma" caused by humans, including a decomposed sea lion with its head sliced off found washed ashore Tuesday in a West Seattle cove.That's according to Seal Sitters Marine Mammal Stranding Network, a group that responds to reports of stranded or dead sea lions.Michael Milstein, a NOAA Fisheries spokesman, has confirmed the deaths of five California sea lions in West Seattle, including four that died of gunshot wounds.NOAA Fisheries law-enforcement agents are investigating these crimes, which are prohibited under the Marine Mammal Protection Act.Between 1998 and 2017, National Geographic reported up to 700 California sea lions were found with gunshot and stab wounds in waters off California, Oregon and Washington. 955

SEATTLE (AP) — Researchers say a London man appears to be free of the AIDS virus after a stem cell transplant. It's the second such success including "Berlin patient" Timothy Ray Brown.Such transplants are dangerous and have failed in other patients. The new findings were published online Monday by the journal Nature.The London patient has not been identified. He was diagnosed with HIV in 2003. He developed cancer and agreed to a stem cell transplant to treat the cancer in 2016.His doctors found a donor with a gene mutation that confers natural resistance to HIV.The transplant changed the London patient's immune system, giving him the donor's HIV resistance. 674

SAN MARCOS, Calif. (KGTV) - Students at Cal State-San Marcos will spend time Tuesday and Thursday this week painting as a way to process their emotions in the wake of the school shooting in Parkland, Florida.They're making a pair of murals, in conjunction with the Art Miles Project.One mural features 17 peace signs, each with the name of one of the victims of the shooting. The other features a dove with 17 rays of color coming out of it, also honoring the victims.Organizers say it's their way to let the victims know they have support from all over. It also helps the people who are painting sort through their own emotions and grief."I see the healing power that it has," says Joanne Tawfilis, the Director of the Art Miles Project, which organizes the murals.She's been doing murals like this for 20 years. Every time there is a major shooting or natural disaster, she organizes a way for people to paint."It makes me feel good," she says. "But it also makes me feel sad that we’re in a state in the world that this violence continues."Over the last 20 years, the Art Miles Project has been involved in painting 5,000 murals in over 100 countries. All of the materials are donated.In addition to the two murals that students will paint at Cal State-San Marcos, Tawfilis says the public is invited to the Muramid Museum and Art Center this weekend to paint more. 1391
