As of Tuesday, Petco says they no longer sell electronic "shock" collars and have removed them from its shelves and website.The company said they stopped selling the human- and bark-activated electronic pet collars in a press release on Tuesday because they wanted to strengthen their commitment to positive reinforcement training methods. They also wanted to solidify their evolution from "a leading pet specialty retailer to a category-defining health and wellness partner" for animals and their owners."Electricity may be critical to powering your microwave, but it has no role for the average pet parent training their dog," said Petco CEO Ron Coughlin in the press release. "Shock collars have been shown to increase fear, anxiety, and stress in dogs, and we believe there's a better way – Positive Reinforcement Training."The San Diego-based company is also calling on the pet industry and consumers to join in its newly launched "Stop the Shock" online campaign that will create "responsible regulation for the retail sale of shock collars to general consumers."Along with today's announcement, Petco also launched a new look declaring itself "Petco, The Health + Wellness Co." to reflect how they've evolved into a health and wellness company."As a health and wellness company, our mission is focused on improving pet lives, and we think selling shock collars does the opposite," Coughlin said in the news release. "It's our responsibility to ensure that we, and others, aren't putting potentially harmful products in the wrong hands." 1551

As the polar ice caps retreat, polar bears could struggle to survive by the end of this century, a number of university researchers wrote in a study published in the Nature Climate Change journal.The study looked at a number of sub-species of polar bears who live in the arctic and how they have adapted to reduced sea ice from 1979 to 2016. The group of researchers said that all but a few sub-species of polar bears will be able to reproduce and survive given projected conditions by 2100.Polar bears use sea ice to capture seals for food. When sea ice erodes for the summer, polar bears fast. Although polar bears are capable of fasting for months, there are limits to how long the bears can go without food.The researchers examined energy needs of polar bears, and that the amount of time polar bears would fast would lengthen to a point that makes it too challenging to survive and reproduce.While resting female polar bears can generally fast for longer periods of time, reproducing females, males and cubs all require shorter fasting periods, the research found.“Avoiding continued sea-ice decline requires aggressively mitigating greenhouse gas rise,” the researchers wrote, “and our results explicitly describe the costs to polar bears of avoiding that mitigation.”To illustrate how much sea ice is being lost, NOAA is projecting that the arctic could have ice-free summers by 2042.Scientists have long discussed the possibility that polar bears could become nearly extinct by the end of the century. Beyond reducing carbon emissions, proposals have included relocating cubs to areas of the Arctic expected to retain higher levels of sea ice have been proposed.

Attention homeowners: if you haven't refinanced in the past year, you may want to think about it.Mortgage rates have dipped to a new low for the 11th time this year.This time, they're at the lowest point they've been since Freddie Mac started tracking rates almost 50 years ago.The national average for a fixed 30-year mortgage is 2.8%, and 2.33% for a 15-year mortgage.That's great news for people who are already in homes and want to stay there, but it won't help most buyers.Home prices are up an average of 15% over last year, as the inventory of available homes continues to fall. 593
