Secret Animal Hideouts

first_imgSmall animals can hide out in secret places, even in your own home.Under the SnowThere’s a world of animals out of sight, living under the snow. Many have seen videos of coyotes hunting rodents in the snow, but there are many more that live in an amazing world called the subnivium—the habitat under the snow. PhysOrg peers into this habitat with artwork of this secret world, “unseen by most humans” and “barely explored” by scientists. Yet most animals on the planet, directly or indirectly depend on the white wilderness.Snow covers some 40 percent of Earth’s land masses year in and year out. And, as scientists are discovering, snow is critical to animals and plants that live in northern latitudes, as well as those in far southern latitudes like Patagonia at the tip of South America. It ensures their—and our—survival.“Without snow, plant and animal life would be completely different,” says biologist Jonathan Pauli of the University of Wisconsin-Madison.Why is this? Ecological webs are interconnected. “Without fungi, wildflowers’ summer bloom in mountain environments wouldn’t happen,” for instance. “Fungi increase their metabolism as winter progresses, releasing nutrients from their by-products as snow melts in spring.” And without plants, much of the food web would break down.Surprisingly, even some desert animals depend on snow. “Gazelles in the Gobi Desert in northern China and southern Mongolia rely on ‘snow mines,’ oases of water from melting snows buried beneath the sand.” And along with the mice under the snow, many other species of bugs, worms, rodents and even birds find refuge in the constant temperature provided by “nature’s igloo.”In Your HomeThe news media had fun announcing a new survey of arthropods (invertebrates with segmented bodies and jointed appendages) that live in human houses. Scientists at North Carolina State found a much greater diversity than expected:Your home is a jungle inhabited by 100 different species (New Scientist)Hundreds of Tiny Bugs Are Probably Hiding in Your Home (Live Science)500 Kinds of Bugs May be Living in Your House (National Geographic)For some homes it could be well over 500 species. They’re found in every room of the house: ants, flies, spiders, silverfish, crickets, beetles and more. Live Science posted a gallery of 15 common indoor dwellers, including gnats and daddy-longlegs. Homeowners had this reaction when the scientists showed them what they found: “The residents were really surprised and often horrified that we found so much, so we had to calm them down by saying it was normal.”Now you know why those cobwebs keep showing up between dustings. Thankfully, most of our uninvited house guests are harmless, and they generally try to remain out of sight. Some are even beneficial, the scientists said:The carpet beetles and book lice do much of the clearing up, scavenging dead insects, moulds and algae, as well as polishing off food crumbs and detritus from our own bodies, including nail clippings, hair and dead skin. Some carpet beetles live on and consume spiders’ webs. [New Scientist]They won’t hurt you, either, the researchers added. Although many of the species that Bertone and his colleagues found were predatory — like spiders, centipedes, wasps and beetles — they can’t bite people. In fact, some may actually help out around the house by consuming harmful species — the arthropod equivalent of pitching in with household chores. [Live Science]So keep moving; nothing to see here.  “Just keep living your life how it is,” Bertone advised. “This has been happening for a long time.”Add this to the fact that most of the cells you carry are not your own, although Nature busted the myth that we carry 10 times more microbes and bugs than our own cells; it’s more like 1:1. That’s a relief. They’re not all germs, of course; we all have tiny mites that live in our eyelashes and hair follicles, but that’s too disturbing to think about, so we won’t tell you about that.We may as well accept the fact that we share our habitats, both indoors and outdoors, with other creatures. Instead of becoming horrified, we can learn to accept this as normal, unavoidable, and actually good—to a point. It’s OK to set out roach traps and wipe up the ant trails, but you don’t have to run around the house spraying everything with Raid. Live and let live. Parents, you can help your kids avoid paranoia by treating bugs matter-of-factly and not screaming at the sight of every spider or bee. Calmly teach them to look at it and learn about its way of life. Instead of stomping on it, show the kid how to take the little friend gently outside where it belongs. Correct the urban myths that come and go, like notions that everyone eats bugs and spiders during their sleep. Obviously, some pests that can cause disease (lice, fleas, bedbugs, houseflies) need to be controlled, but avoid calling arthropods “nasty vermin” and other dark, scary terms. Most are harmless, and all of them were harmless in the original good creation.It can be disconcerting, though, to run into an unexpected arthropod. I remember laying in bed one night reading when [Warning: Do Not Tell This Story to Young Children] a big hairy mygalomorph (a large black spider like a tarantula) strolled into the bedroom. I jumped up, but before I could catch it, it ran under the bed. After several minutes trying to find it with a flashlight, I gave up and got back in bed. As I was reading, I dangled my hand down and then [cue scary music] felt the hairs of this “monster under the bed” brushing my fingers. Jumping up again, I was determined to get it this time, not wanting to risk having it wake me up in the dark or something. Finally, I caught it under a jar, and imprisoned it in a closed terrarium to show it who’s the king of this castle. (And also to observe and learn about it for science, of course.) Speaking of castles, the wise Agur said, “The spider skillfully grasps with its hands, and it is in kings’ palaces” (Proverbs 30:28). Some translations say it’s a lizard you can catch with your hands, but the point is that even lowly creatures can live like royalty. I don’t live like a king, actually. I can’t afford goldfish, so I just keep silverfish.Small black ants in my part of the country are almost impossible to stop in the summer months (fortunately, cockroaches are less common, but we have black widows to watch out for). Ant trails can stretch clear across the house—that would be a long hike for a human! I marvel at how the scouts locate food and call the whole army within minutes. Spray their entrance, and they quickly find another way, even out of light switches and faucets. We also have Mormon crickets that hop faster than you can step on them. One will start chirping in another room, driving you crazy, but when you approach it, it stops, leaving you clueless where the little ventriloquist was hiding. I think we dislike bugs in the house partly because they outsmart us. If you want to see one of those tiny gnats that hover and dart about, Live Science has a magnified photo of one. Think of all the flight hardware packed into that tiny thing.Speaking of crickets, one night working late in the home office I heard a grinding noise a few feet away under some equipment. This time I suspected what it was, and with a flashlight, there was a big ugly potato bug (also called Jerusalem cricket) doing its thing. Not reachable, I sprayed it with spider spray and it quieted down, but I never found the body. Hopefully some other friendly arthropods will work it over, and it will evolve into a dust bunny.Share your story!  What animals live with you, besides pets?  Lizards have run into my house, and once a Cooper’s hawk flew in the front door with a rabbit in its talons! Some people have to worry about moose and bears wandering in. But we all have a story about arthropods, I’m sure. (Visited 40 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

iwasshot in Joburg: a city in pictures

first_img“iwasshot in Joburg is a [South African] business venture established to provide a platform for former street kids who received photography training through the iwasshot FOUNDATION,” says Bernard Viljoen, the architect who founded the three-month project after community service for a boozy misdemeanour.Bernard Viljoen and the young photographers from the Twilight Shelter, a boys’ outreach centre. They ramble through Hillbrow in Johannesburg’s inner city in search of beauty and stories captured in a frameInitially teaching basic photography skills to street children, the project has expanded and now, flash forward, these budding artists receive six months of photography training, using disposable cameras to document their environment.The young photographers from the Twilight Shelter, a boys’ outreach centre, now ramble through Hillbrow in Johannesburg’s inner city in search of beauty and stories captured in a frame.“From there they receive more in-depth digital photography and computer training for another six months. Once they have completed the year they can join the iwasshot brand and start generating their own income,” says Viljoen.At the end of each year, an exhibition showcases the boys’ photography, which also goes on sale. The establishing shot this year shows boys holding disposable cameras, in a strong stance that says “I know what I am doing and I belong here too”.FROM THE SHADOWS, INTO LIGHTViljoen says, “… how these boys are transformed, from when they started out to being proud citizens, actively participating in their society, discussing their camera angles, colour and composition, it is incredibly humbling to see”.The project aims to enrich the lives of street kids who have found their calling through a lens. Viljoen wanted to further their opportunities, developing a skills transference division to create opportunities for economic growth, social development, and job creation.Solani Dube, a former student at iwasshotin joburg, says he had no self-esteem; he was” living with no direction”. He had never thought of himself as a “normal human being”, but now he is studying law.The words “I was shot in Joburg” can elicit fear, seeming more suited to a newspaper headline, but Viljoen thought it was an expression of life in Hillbrow, with its violent reputation.“I believed that if a brand is relevant, conceptual and slightly controversial, that it will take off. It did. It has now been four years and we are going strong.”Hard at work in the studio, Viljoen wanted to further the boys’ opportunities, developing a skills transference division to create opportunities for economic growth, social development, and job creationViljoen says the project aims to “To create quality products; to establish a brand. We want to become part of the South African economy rather than sitting at a robot begging for a hand-out.”The project’s success has allowed the team to move into a permanent space at Arts on Main in the Maboneng Precinct in Johannesburg’s teeming central business district.Toni Sithole, another student, says, “I am moving forward with myself, I am improving, and I am doing something for myself. I see myself in the future as a person, opening new doors for myself. Hillbrow is a new playground for budding photographers.”He also wanted the boys “to find beauty where you thought there was none. If you move your eye, you can see a different world and whatever you see can make an impact on people”.AN UNFAMILIAR LIFEViljoen is interested in people living on the periphery of society, people who don’t have a voice, but who have experienced so much in their lives.Little previews of city life are exposed in the photographs; glimpses into lives unfamiliar to suburbanites. Shadows reflecting off a leg or a sign are fragments, enticing viewers to look deeper and be witness to a transformation, an invisible human being becoming a person with a voice.Viljoen believes consistency is important with his charges as they have had such volatile, tumultuous lives. So each week, he showed up.He says, “For some of the boys, the project has also meant feeling more at home. There are stories of neglect, abuse, being orphaned. Abandoned in different ways by the families and systems that give children the love, support and nurturing they need. Iwasshotin Joburg is a way to claim something back, to make something of value, to be of value.”Sandile Mdlalose says, “I used to eat out of rubbish dumps and beg. [Now] When people talk to me, they speak to me as if I am a big person. Everyone can do something for themselves; it doesn’t matter where you are from. I believe in myself now, I have a strength that I never had before.”“I tell them the cameras are like our little AK47s,” says Viljoen. “They give us permission to walk the street. If you keep it in your hand it elevates you above the everyday street life.”The project’s success has allowed the team to move into a permanent space at Arts on Main in the Maboneng Precinct in Johannesburg’s teeming central business district (Images: iwasshot in joburg team)To Viljoen, Johannesburg is the most interesting, textured city in South Africa.“I’m lucky enough to work almost solely in the heart of the city, and over the years it’s become more striking to me. It’s the synergy of history, drive for success, passion and interesting, warm people that give Joburg a buzz of energy.“If you walk around and experience the space – new and old – you’re always treated to a visual overload. Suburban dwellers, who don’t hit the streets of Joburg, never really see or understand its beauty. They’re blind-shot by unjustified fear.”The snapshots, he says, capture the beauty, intriguing spaces, textures layers, and diverse people of Johannesburg.“Hillbrow is an assault on the senses … the towering blocks of flats draw your eyes upwards and you’re mesmerised by the rainbow-coloured clothing hanging on practically every balcony, the rowdy sounds of street vendors bargaining and schoolchildren laughing and chatting.“There are contrasts … the countless broken window panes glistening in the sun and the vivid colours of the fresh fruit sold by the vendors … the boys see photo opportunities lurking on every corner. Over the years, they’ve produced really powerful images.”Pritchard Ndlovu manages the studio at Arts on Main. He says that the iwasshot space has changed his life; he now has a future and it’s thanks to the lens; “The photos allow the boys to tell stories. It is an incredible initiative that brings joy to the boys and inspires a sense of belonging.”Viljoen adds: “I have succeeded in this if every kid is able to tell a story with their photos – their own – if I can make them feel worthy of sharing it with the world, visually documenting their stories, their observations, their hopes and dreams.”First published on Media Club South Africa – Brand South Africa’s library of quality images and articles, available for free.last_img read more

Nest Thermostat Data Revealed for First Time

first_imgThe first one (at left) shows huge opportunities for saving money and energy for homeowners. It’s the top 10% of strip heat users, and according to Blasnik, they were burning an incredible 240 kilowatt-hours per day on the coldest days. Wow! (I’ve written about how common it is for heat pumps to run strip heat when they shouldn’t.) Heating setpoints and temperature floatThe chart at left shows thermostat setpoints during heating season in a few select states. Vermont won for lowest setting at about 60°F. I don’t have a photo, but he also showed heating systems in use by time of year and outdoor temperature. I think Vermont won that one, too, in terms of lowest outdoor temperature before turning on heating systems, but I didn’t get a photo. I do recall there was a small bump of people turning on heating systems when the temperature in Vermont dropped to the 50s (?), and Mike Rogers of Omstout Consulting, a Vermonter, said, “Those are the New Yorkers.” Air conditioner runtime and humidityThe graph at left is a bit confusing, but if you spend some time with it, you’ll reap the benefits. It shows when heating and cooling are happening throughout the year, how the indoor relative humidity changes, the relative humidity in the 90th percentile of homes, and what percentage of homes have humidity above 60%.Notice that spike in homes with humidity above 60% that occurs in October? It seems to support something I wrote a few years ago: Why Is Fall a Good Time of Year for Window Condensation?The next three graphs show indoor relative humidity as a function of air conditioner runtime. The results may challenge your beliefs and call into question what we’ve been teaching for a long time now, so you may want to sit down before taking a look. Ready? Here’s the first one (the graph at left). These are all for homes in Charlotte, North Carolina, a mixed-humid climate.See the trend? Neither do I. There’s no pattern there, just a scattering of data points all over the graph. But this was just for a single day, 14 July 2014, so we probably just need to look at more days, right? How about these? The Nest thermostat has been around since October 2011, quietly collecting data on how your home — and the homes of hundreds of thousands of your neighbors — operates. It gathers information about indoor temperature, relative humidity, air conditioner runtime, auxiliary heat operation for heat pumps, and much more. Unlike the Ecobee thermostat, however, Nest doesn’t let its owners see all those data (which is a problem only for energy geeks really). Enter Michael Blasnik.Blasnik, a building science and data guru, consulted on the Nest while it was under development and after its release. He has since joined the Nest team and is now a Google employee, and he’s been having a lot of fun looking at the data and trying to understand what they’re saying.At the ACI conference in New Orleans last week, he gave attendees a first look at some of those data, and my, what a treasure trove he’s got his hands on! The room was packed, as you can see in the photo above. I took that photo a few minutes before the session began. After it started, a lot of people were standing in the back as well, and I’m sure many decided to go to a different session because they couldn’t get in.So let’s get into the data. Blasnik showed 60 graphs of data, and I didn’t take pictures of all of them. Below are the ones that seemed most interesting to me. (It’s really hard to try to take notes, take pictures, and think about what you’re seeing all at the same time.) The slide at left shows data for four different temperature ranges, and it’s not until you get to the mild days with temperatures between 65°F and 75°F that we see the trend we expect. What the heck is going on here?!Of course, runtime and indoor relative humidity are only two variables that factor into the question of air conditioner performance. One thing that HVAC systems with air distribution can do is change the pressures inside the house. Unbalanced duct leakage can bring more outdoor air into the house, and that could be what’s happening here. We know the typical home has leaky ducts. We also don’t know anything about how tight the building enclosure of these homes is. What we’re seeing above is an average of what’s going on in a whole lot of homes, so we really can’t draw any conclusions yet.Blasnik showed similar data sets for other cities: Houston and Dallas (about 1000 homes each), Minneapolis, Washington, DC, and more. The Houston and Dallas data showed the same patterns as Charlotte. Minneapolis did show a decreasing trend on the hot days, which Gary Nelson, founder of The Energy Conservatory, said was probably because the ducts are inside the building enclosure there.The takeaways from these data for Blasnik were that air conditioners are doing a pretty good job with latent control and there’s no real evidence of oversizing based on the runtime data he’s looked at. Also, very few homes went above 60% relative humidity, and even in the places where the curve is flat, the relative humidity is around 50%, which is right where you want to be.Heat pump auxiliary heatI’ll close with a couple of Blasnik’s slides on electric resistance auxiliary heat (strip heat) use in heat pumps. More interesting, though, is what’s happening with the indoor and outdoor temperatures when the AC is running. Look at the fourth column in the table at left. The top number is the percentage of runtime hours that occur when the outdoor temperature is lower than the indoor temperature.Notice that in cold climates this happens 30% of the time. Not too surprising since they’re probably the same people who say Atlanta is hot and muggy when they move to the South. (No, Houston, New Orleans, and Tampa are hot and muggy. Atlanta has a really nice climate!) What did surprise me is that it’s 21% in mixed-humid climates. Yes, right here in Atlanta, the average Nest thermostat owner runs their AC one out of each five hours when it’s nice outdoors than indoors. Hmmm.If that seems a little odd and wasteful, consider the second number in that column. It shows the enthalpy difference between indoors and outdoors, which captures the effect of humidity, too. Notice that an AC in a mixed-humid climate runs only 4% of the time when it’s nicer outside than inside based on temperature and humidity, so it’s not as bad as it looks based on temperature only. The graph at left shows a really interesting fact about heating degree days. The temperature float referred to there is the difference between indoor temperature and outdoor temperature when the heating system comes on. If the thermostat is set to 70°F, for example, the average home’s heating system doesn’t kick on until the outdoor temperature is 58°F. So there’s your average base temperature for heating degree days, at least for homes with Nest thermostats. RELATED ARTICLESReinventing the ThermostatThe Strange Geography of Thermostat Settings Nest Thermostat Pays for Itself in Two Years, Studies FindGet Ready for Smart AppliancesThe Internet of Things Takes Center StageGBA Product Guide: The Nest Learning Thermostat Air conditioner runtime and temperatureThe Nest, of course, monitors air conditioner (and heating system) runtime. That’s the main statistic that owners get in their monthly report. The chart at left shows data on the length of air conditioner runtime on design days. A little over half of the homes have runtimes that last at least two hours. About a third of the homes have four hour runtimes. Only about 10% of the homes have runtimes that last eight hours or more, which means they’re basically running continuously through the hottest part of the day. The graph at left shows strip heat use for all heat pump owners. You can see that in the median homes (represented by the black line), the heat pump’s supplemental heat kicks on at about 40°F. The worst homes are using strip heat at outdoor temperatures above 60°F. (I wonder how low the heating degree day base temperature might be if the worst homes were excluded.)The best 25% of homes are getting only about 10% of their heat from the strips even when the temperature is down at 10°F. Blasnik also threw out some numbers about the low temperatures they’ve seen where some homes are still getting 100% from the heat pump, but I didn’t write them down. D’oh! (I’m afraid Edward Tufte would not approve of this graph, but to be fair, Blasnik admitted that he struggled with finding a good way to present these important data and the rest of his graphs are great. The shaded regions give the false impression that their areas represent the number of homes subject to those conditions. That is an incorrect impression, however, as the number of homes contributing to the data below the black line is equal to the number included above the black line. For more on this topic, buy yourself a copy of Tufte’s excellent book, The Visual Display of Quantitative Information.)A great startThe data that Blasnik showed us at the ACI conference were astounding. When I was talking to him afterward, he said they have enough data for a dozen or more grad students to write doctoral dissertations on. Let’s hope Nest will release them. Even better, give us a searchable database!But let’s also give props to Nest for collecting the data and letting Michael share some of them with us at ACI. Whether you have a Nest thermostat or not, these data can help everyone by adding to our understanding of how homes really work. Allison Bailes of Decatur, Georgia, is a speaker, writer, energy consultant, RESNET-certified trainer, and the author of the Energy Vanguard Blog. Check out his in-depth course, Mastering Building Science at Heatspring Learning Institute, and follow him on Twitter at @EnergyVanguard. Hmmm. Most of us in the world of building science have been preaching the gospel of AC runtime as a the cure for high indoor relative humidity. The data above, for warm days in a mixed-humid climate, provide no evidence that what we’re saying is correct.In fact, if there’s a trend in those data above at all, it’s the opposite: Higher AC runtime results in higher indoor relative humidity (see graph at left). It’s not a strong trend in that direction, but still, even if it’s flat, it’s not what we expect to see.last_img read more

Bruins force Stanley Cup Game 7 with 5-1 win over Blues

He smothered a big Colton Parayko slap shot with Chara in the box near the end of the first period, and made a fancy glove stop on an even-strength try for Brayden Schenn 7:42 in the second.He got some help after Marchand was whistled for tripping Alex Pietrangelo midway through the second. With the Blues applying heavy pressure in search of the tying goal, Pietrangelo had a backhand go off the left post and Rask’s back before McAvoy knocked the puck out of the way out of midair.“We weathered the storm pretty good,” Rask said.While St. Louis came up empty on the power play, Boston used a 5-on-3 advantage to jump in front in the first. With Schenn and O’Reilly in the box, Marchand beat Binnington with a sharp-angled shot from the right circle at 8:40.It was Marchand’s first goal since he got an empty-netter in Boston’s 4-2 victory in Game 1. The Bruins improved to 25-1 when the pesky veteran scores in the postseason.“We knew that again the start was going to be key and that they were going to give us a push early and to manage that and play well and take care of details and obviously capitalize on our chances,” Boston center Patrice Bergeron said.Marchand and company then put it away in the third.First, Jake DeBrusk won a board battle with Pietrangelo to set up Carlo’s bouncing shot that went off Binnington’s arm for the defenseman’s second career playoff goal. Then Kuhlman, a rookie who was in the lineup in place of former Blues captain David Backes, made it 3-0 with a well-placed wrist shot at 10:15.After O’Reilly supplied some hope for St. Louis when he was awarded a goal after a review by the officials, Marchand found Pastrnak in front and the winger put a slick move on Binnington to make it 4-1 on 14:06.
