BALTIMORE — The University of Maryland, Baltimore has suspended an experiment they were conducting after reports indicate they were denying pain relief to animals they were operating on. The university confessed they were forced to stop their experiment because they failed to comply with multiple federal regulations, according to the national watchdog group SAEN, or Stop Animal Exploitation NOW!, which monitors U.S. research facilities for illegal activity and animal abuse.While the details about the experiment are still limited, documents from UMB reveal the project was suspended because animals were repeatedly denied pain relief after surgeries, they were not given proper time to recover after surgeries, the staff did not euthanize them after they reached their endpoints and the staff did not properly keep records. In a letter to the University of Maryland Board of Regents, SAEN said animals were not given any pain relief during a procedure involving cardiac arrest, and instead of giving the animals a three- to seven-day recovery period, they were given up to 24 hours. It also said animals were inspected by veterinarians and one animal required euthanasia, but was kept alive. All of this was discovered during multiple separate lab inspections done by UMB research administration. The letter also says during those inspections, the lab was notified of the serious consequences of not providing pain relief to the animals, but still did not get the necessary medications by the time another inspection took place, even though a surgery was going on at the time of the second inspection. After another unannounced inspection, changes were still not made, so the experiment was suspended on October 25. Now, SAEN is urging for UMB to do further research of abuse, terminate the project and refund all of the project support, .9 million, to the federal government. "This failed experiment must be terminated immediately,” said Michael A. Budkie, a co-founder and executive director of SAEN. "The idea that a principal investigator repeatedly violated their own protocol and denied pain relief to animals indicates a total disregard for proper scientific procedures and total contempt for the authority of UMB Research Administration." SAEN is also calling for the results of the research to not be published because protocol was not followed. 2477
BIG BEAR LAKE, Calif. (AP) — An egg has been laid in a nest shared by two bald eagles in Southern California and nature lovers will anxiously watch for the hatching via an online live feed .U.S. Forest Service biologist Robin Eliason said Wednesday that the parents will share incubation duties for the next month or so. Eliason expects the hatchling will arrive in early April.The video feed shows an eagle nestling on the egg Thursday as strong, cold winds blow through the San Bernardino National Forest. A count completed late last year found 11 bald eagles living in the forest east of Los Angeles.The Institute for Wildlife Studies web page has thousands of comments from people watching the feed. The camera was installed by the group Friends of Big Bear Valley.Watch the live feed of the eagles below: 817
Black Friday is changing this year and it may actually be less hectic than usual.Because social distancing is so important, stores are doing what they can to mitigate crowds. That includes doing away with hourly deals.“You used to have to line up to get that 6 a.m. deal, that 5 a.m. deal, and retailers are making it a lot easier to get deals over the course of Black Friday or over the course of the entire weekend to discourage you from waiting in those lines on Black Friday and bunching up in crowds like they're trying to avoid,” said Lisa Rowan, personal finance expert at Forbes Advisor.Lines will be socially distanced, and stores will be monitoring how many people are in the store at once.Sale prices will also be extended to online orders that you can pick up in store or curbside.There will also be great Cyber Monday deals, but make sure you get those orders in as soon as possible.“If you're planning on shopping online during Black Friday weekend, now is the time to do it, because it gives you a little bit of extra time to make sure those packages are going to get to you before you want to put them under the tree,” said Rowan.A lot of retailers will not be open on Thanksgiving Day, so keep that in mind while you plan ahead.Deals are expected to last all through December. 1301
BENOUVILLE, France (AP) — With the coronavirus pandemic preventing people traveling, this year's D-Day commemoration is a very different event. For families anguished that they can't be in Normandy themselves, an Englishman who lives there is laying wreaths on their behalf. Steven Oldrid says it is an honor to do it. He is also filming ceremonies and wreathlayings for the families. In return he gets their grateful thanks — and a few items of British food in the mail. 479
BALTIMORE, Maryland — In the early hours of Jan. 19, 2015, the 15-foot Christmas tree proudly displayed in the Great Room of a large Annapolis, Maryland mansion caught fire.It spread through the home killing Sher Grogg's brother, sister-in-law, and their four young grandchildren.“They just didn’t have enough time to do anything, and it was under three minutes and everything was gone,” Grogg said.It's painful for her to talk about, even more distressing to see rooms engulfed in flames, but as an advocate for Common Voices, a coalition whose mission is a fire safe America, she witnesses fire demonstrations.“Oh, it’s horrible. And actually, really horrifying for me to see because I know my brother was right in the middle of a room that had flashover and that was his last experience,” said Grogg.This is her outlet to grieve. She's found purpose in educating and warning others. Had her brother’s home had fire sprinklers, she thinks her family would still be here today.“You can replace material things, but you can't replace a life and that's the difference. You really need to consider fire sprinklers to save the lives of your family,” said Grogg.Shane Ray is the president of the National Fire Sprinkler Association. He’s been in the fire service since 1984 and has seen how smoke detectors alone are not enough to prevent deaths.“We have more contents in our home than we've ever had before and most of those contents are made out of synthetic materials, so it produces a much more toxic smoke, much faster and much more deadly,” Ray said.On Thursday, he demonstrated how quickly a fire spreads. Within a minute, flames and smoke engulfed a tiny room. The smoke alarm sounded then the sprinklers went off. In a side-by-side comparison, the same room, without sprinklers, is completely destroyed by the fire.Ray said the sprinklers give families time to evacuate, buy firefighters time to get to the incident, and can save the lives of our pets.“Ninety-six percent of fires are contained with just one sprinkler. This is the sprinkler that came out of that fire. So, if we had another 10 rooms in the house, this is the only sprinkler that would activate. It's not tied to the smoke alarm, it's not tied to anything else, it's individually heat-activated,” said Ray, attempting to dispel some myths surrounding sprinklers.The heat in a room must reach 155 degrees before the bulb in the sprinkler shatters, releasing water. Burnt toast or cigar smoke will not set off fire sprinklers.According to the National Fire Protection Association, more than 2,500 people die in home fires each year. Sprinklers decrease the risk of dying in a house fire by 80 percent.Grogg also wants to remind people with this upcoming holiday season to water your tree every day, get rid of it right after the holiday, and unplug your tree every night.National Fire Prevention Week runs through Oct. 13.
