Paragraph: Roughly half of Yellowstone’s 4,600 bison are estimated to have been exposed to brucellosis, a bacterial infection that can sometimes cause cows and bison to miscarry. Worries that infected bison may endanger cattle in states such as Montana that border Yellowstone had prompted the powerful ranching lobby to endorse biobullets - absorbable projectiles packed with vaccine. They would cut disease rates among bison by as much as 35 percent over 30 years. The proposal was the latest decades-long efforts to ease conflicts between livestock interests and wildlife advocates over management of Yellowstone bison. Park officials said they decided against the remote vaccination program because of its $9 million price tag, questions about its effectiveness and the possible impact on the millions of visitors who flock to the park to view iconic Western wildlife like bison. The measure would have required shooting the animals once a year for three decades, raising questions about how increased human interaction could affect bison within the wild herd. “We have concerns about how that repeated contact might impact bison behavior and their visibility to park visitors,” said Yellowstone spokesman Al Nash. Nash said there was no documented case of wild bison transmitting brucellosis to cattle, which he said signifies the success of existing measures designed to separate the park’s herd from domestic livestock. Those practices include returning bison that leave the park, testing and vaccinating bison that leave Yellowstone, and slaughtering some infected animals. Errol Rice, executive vice president of the Montana Stockgrowers Association, said the threats posed by infected bison to Montana’s brucellosis-free certification, which protects the market value of cattle, warranted using biobullets. He said the program would have lessened the public outcry that erupts when wandering bison are corralled and shipped to slaughterhouses. “The capture and removal of bison has been a challenging issue for the park and Montana. Remote vaccination would have helped alleviate the public relations burden we have to deal with when bison migrate out of Yellowstone,” he said. Stephany Seay, spokeswoman for Buffalo Field Campaign, a bison advocacy group, applauded the park’s decision not to shoot bison with vaccine. “It was a mismanagement scheme based on a livestock model. We don’t vaccinate skunks against rabies or mosquitoes against West Nile virus,” she said. Claim: Yellowstone managers reject vaccinating bison with biobullets.
Yellowstone National Park managers have rejected a plan to use air rifles to shoot the nation’s last herd of purebred bison with so-called biobullets containing a vaccine against a cattle disease, in a decision that has riled the U.S. livestock industry.

Paragraph: Depression is one of the most common forms of mental illness, affecting more than 350 million people worldwide. It is ranked by the World Health Organization as the leading cause of disability globally. Treatment usually involves either medication, some form of  psychotherapy or a combination of both. Yet many patients fail to get better and suffer recurring bouts of illness. MBCT was developed to help such people by teaching them skills to recognize and respond constructively to thoughts and feelings associated with relapse, aiming to prevent a downward spiral into depression. In the first large study to compare MBCT and anti-depressants, researchers found little difference in outcomes. In terms of cost, mindfulness training — often viewed as more costly because it requires more time with a trained therapist — was not significantly more pricey, particularly when given in group sessions, the study found. Richard Byng, a professor at Britain’s Plymouth University Peninsula Schools of Medicine and Dentistry, said that, while current standard treatment for chronic depression is to keep taking anti-depressants, many people don’t want to take them for long periods and others want to avoid side-effects. In this study, 424 adults with recurrent major depression who were on maintenance anti-depressant drugs were randomly assigned either to come off their anti-depressants slowly and receive MBCT or to stay on their medication. While 212 patients continued taking their anti-depressants, the other 212 attended eight group mindfulness therapy sessions and were given daily home practice as well as an option to have four follow-up sessions over a 12-month period. Study results published in The Lancet medical journal showed that after two years, relapse rates were similar in both groups — at 44 percent in the therapy group versus 47 percent in the anti-depressant drug group. “Whilst this study doesn’t show that mindfulness-based cognitive therapy works any better than maintenance anti-depressant medication in reducing the rate of relapse ... these results suggest a new choice for the millions of people with recurrent depression on repeat prescriptions,” said Willem Kuyken of Oxford University, who worked with Byng on the research. Claim: Mindfulness therapy as good as medication for chronic depression - study.
Mindfulness-based cognitive therapy (MBCT) may be just as effective as anti-depressants in helping prevent people with chronic depression from relapsing, scientists said on Tuesday.

Paragraph: There are a number of devices and appliances that have been standard household items in American homes since before most of us were born. Electric irons, dishwashers, vacuum cleaners, gas (or electric) stoves and ovens, washing machines, and clothes dryers are but a few of the many labor-saving devices so familiar to many of us that we seldom ponder just how they work. Ask the average person, for example, how a clothes dryer works, and you’ll probably get an “Are you kidding me?” look in return, along with a terse explanation that a dryer makes stuff “hot,” and everybody knows stuff dries faster when it’s hot. That explanation isn’t technically wrong (as far as it goes), but it’s overly simple. Knowing a bit more about the process involved is the key to understanding why the advice to keep your dryer’s lint filter clean can help improve the performance of your clothes dryer. In a standard (gas) dryer, a fan pulls fresh air into the dryer and sends it flowing over a gas burner. The burner heats the air, which is then channeled into a tumbling drum where the wet clothes are held. The heat, air flow, and tumbling motion all contribute to evaporating the moisture held in the fabrics, and that moisture is absorbed by the gas-warmed air. (Warm air is capable of holding more moisture than cold air.) The warm air — and the moisture it now holds — passes through a filter to trap lint and other particulate matter stirred up by its movement and is vented to the outside so that it can be replaced with new, less-moist air. This process repeats until enough moisture has been evaporated and carried away for the clothes to be considered sufficiently “dry.” Of course, if you neglect to clean the lint filter between dryings, or something else occludes the filter, moist air cannot be vented from the dryer as easily. The result will be that your dryer will work less efficiently: you will have to run your dryer longer to dry a load of clothes, which means higher electricity and gas charges for you and a potentially shorter lifespan for your dryer:  I had a wonderful morning, the heating unit went out of my dryer! Why does everything seem to fall apart this time of year!??? The guy that fixes things went in to the dryer and pulled out the lint filter. It was clean. We always clean the lint from the filter after every load of clothes. He told us that he wanted to show him something. He took the filter over to the sink and ran hot water over it. Now, this thing is like a mesh — I’m sure you know what your dryer’s lint filter looks like — WELL … the hot water just laid on top of the mesh!!! It didn’t go through it at all!!! He told us that dryer sheets cause a film over that mesh and that’s what burns out the heating unit. You can’t SEE the film, but it’s there. He said this is also what causes dryer units to catch fire and potentially burn the house down with it! He said the best way to keep your dryer working for a very long time (and to keep your electric bill lower) is to take that filter out and wash it with hot soapy water and an old toothbrush (or other brush) at least every six months. He said that makes the life of the dryer at least twice as long! How about that? Learn something new everyday! I certainly didn’t know dryer sheets would do that. So, thought I’d share! Note: I went to dryer and tested my screen by running water on it. The water collected a little but ran though the screen. I dried it off and was ready to put it back in the dryer since the water ran through it but, I thought was the heck it won’t hurt to wash it while I had it out. Warm soap water and a nylon brush and I had it done in 30 seconds. I then ran the water over the screen and what a difference the water just gushed through it with no puddling at all and this time I was running the water at a faster rate. That repairman knew what he was talking about. So, keeping the lint filter clean is one simple way to increase the efficiency  (and decrease the operating costs) of your dryer. Just removing the lint from the filter isn’t always enough:  the fine mesh of most dryer filters can be clogged in ways that aren’t obvious at a casual glance. As suggested by the piece quoted above, softener sheets can cause waxy build-ups on lint screens that require a little extra effort (usually no more than a quick scrub and rinse in warm, soapy water) to remove. Many modern dryers also use moisture sensors rather than ordinary timed cycles, and residue from dryer sheets can coat the sensors and interfere with their ability to function properly. Cleaning the sensor screen with a little detergent and a soft brush, and wiping off the sensor itself with a cotton ball and some rubbing alcohol can rectify this problem. Although regular cleaning of the lint trap may help your dryer to work more efficiently, it’s unlikely that the lack of such cleaning will result in your dryer’s motor burning out or, worse, catching on fire and burning your house down. Consumer Reports noted of this claim that:  At Consumer Reports we’ve tested hundreds of clothes dryers for our ongoing dryer Ratings and recommendations. CR’s appliance director, Mark Connelly, says it’s possible that over a long period, fabric sheets, fabric softeners, and laundry detergent ingredients contribute to an unseen film or waxy buildup on the dryer lint screen. But “it’s highly doubtful,” he said, “that any such invisible buildup alone leads to heating-unit burnout or a fire.” Claim: Washing the lint filter in your clothes dryer can help enhance the performance and lifespan of that appliance and avoid fires.
