![]() ![]() It's no different than experiencing horseflies and mosquitoes. "You should take advantage of all the recreational opportunities in Alberta, just be aware of what the risks are. That doesn't mean people should stop going to their favourite lakes, he added. It's important to keep that ecological value in mind lakes aren't meant to be as pristine as swimming pools." "Lakes in Alberta often support high biodiversity of animals we recognize and the parasites that infect them. While knowing what causes swimmer's itch ups the ick factor for swimmers, Alberta lakes naturally harbour large snail populations due to their shallow depths and high nutrient content, so it's incorrect to assume swimmer's itch is a by-product of poor water quality or unhealthy lakes, Hanington noted. What is likely the most prevalent snail species in central Alberta, Stagnicola elodes, was found in every lake surveyed and is also able to transmit the parasite that causes the condition, Hanington noted. They also discovered that every common aquatic snail species in Alberta carries at least one species of parasite that causes swimmer's itch. In Alberta alone, the website has recorded case reports from 101 lakes across the province. between 20 and were able to conclude that swimmer's itch could be a problem at any lake in the country. Using the website survey, he and his team studied 3,800 self-reported cases across Canada and the U.S. Unfortunately, there's no way to completely avoid swimmer's itch if people want to make a splash in Alberta's lakes, Hanington noted. The website provides updates on swimmer's itch research, an online survey that lets people report their cases and a resulting map that shows the shifting locations and dates of outbreaks (factors like wind and time of day can influence where the parasite is most abundant), so they can decide whether they want to visit a particular lake that day. We want to use it as a tool to connect with people." "We want to help people make informed choices about where they swim by providing information on where swimmer's itch is occurring and through education, which is what the website provides. The website was created to measure how widespread the issue is by connecting with "citizen scientists," said Patrick Hanington, a researcher with the School of Public Health. RELATED: What lies beneath the surface: examining water-borne parasites.RELATED: 4 common water rashes and what you can do about them.Swimmer's itch is contracted by swimming in lakes, and is caused by the larvae of a worm-like parasites that are released into the water by infected snails and can penetrate the skin to cause the itch. The parasites move with water and wind, so can concentrate on shorelines. If it's safe to do so, swim further offshore, where there's less chance of getting swimmer's itch.If a rash develops, it's likely you'll develop a worse case of swimmer's itch by re-entering the water. ![]() At first, don't spend a long time in the water-get out after 10 minutes and check your skin for red spots.Avoid early-morning dips-that's when the parasites tend to emerge from their snail hosts and are most active.Be aware that July and August are peak season for swimmer's itch in Alberta lakes.How to minimize your chances of getting the rash SWIMMERSITCH.ca lets people report their own cases of the rash, alert others to problem areas around North America, learn more about the condition and fill out a survey that helps U of A researchers pinpoint when and where the parasites that cause swimmer's itch are most prevalent. People wondering about catching swimmer's itch can get in the know with a University of Alberta website before heading to the lake this summer.

The observations also provide one of the most stringent tests to date of Einstein’s theory of general relativity: this predicts a rounded shape of the black hole’s halo, in line with what EHT has observed. The observations are already giving scientists new insights into the weird environment close to black holes, where gravity is so fierce that reality as we know it is distorted beyond recognition.Īt the event horizon, light is bent in a perfect loop around the black hole, meaning if you stood there you would be able to see the back of your own head. ![]() This meant waiting for half a year for the South Pole data, which could only be shipped out at the end of Antarctic winter. ![]() The sheer volume of data generated was also unprecedented – in one night the EHT generated enough data to fill half a tonne of hard drives. “We got super lucky, the weather was perfect,” said Ziri Younsi, a member of the EHT collaboration who is based at University College London. And, on one night in April 2017, everything came together. Observations at the different sites were coordinated using atomic clocks, called hydrogen masers, accurate to within one second every 100 million years. The success of the project hinged on clear skies on several continents simultaneously and exquisite coordination between the eight far-flung teams. “We hope to get that very soon,” said Doeleman. The collaboration is still working on producing an image of the Milky Way’s black hole. The second target, which yielded the image, was a supermassive black hole in the galaxy M87, into which the equivalent of 6bn suns of light and matter has disappeared. ![]() First was Sagittarius A*, the black hole at the centre of the Milky Way, which has a mass of about 4m suns. When observations were launched in 2017, the EHT had two primary targets. ![]() The EHT achieved the necessary firepower by combining data from eight of the world’s leading radio observatories, including the Atacama Large Millimetre Array (Alma) in Chile and the South Pole Telescope, creating an effective telescope the size of the Earth. This was once thought to be an insurmountable challenge. A lot of this material is destined for oblivion, although some of it is ejected as powerful jets of radiation.īut black holes are so small, dark and distant that observing them directly requires a telescope with a resolution equivalent to being able to see a bagel on the moon. This is the point at which escaping would require something to travel at faster than the speed of light – which as far as we know nothing does – so it is the point of no return.īlack holes are surrounded by an accretion disk of dust and gas, orbiting at close to the speed of light. The edge of the black hole is defined by its so-called event horizon. The equations predicted that, beyond a certain threshold, when too much matter or energy is concentrated in one place, space and time collapse, leaving behind a sinkhole through which light and matter can enter but not escape.Īt first these were thought to be mathematical oddities, rather than real astronomical objects, but in the past century overwhelming evidence has confirmed that black holes are out there. Black holes were first predicted by Einstein’s theory of general relativity, which reimagined gravity as the warping of space and time by matter and energy. ![]() For his screenplay, Tarantino won an Academy Award, a Golden Globe, and a BAFTA. Waltz won several awards for his performance, among them Best Supporting Actor at the Academy Awards, Golden Globes and BAFTAs. The film received numerous awards and nominations, winning two out of five nominations at the 85th Academy Awards. ![]() The film received acclaim from critics, mainly for Waltz's performance and Tarantino's direction and screenplay, though the film's usage of the word " nigger" and its depiction of extreme and graphic violence drew controversy.

So there is no reward for feeding the Pokémon to keep it happy and no reward for guarding the gym for days. And I get the money only once the Pokémon is returned, regardless whether it was in there for 10 hours or 5 days - 50 coins on the day the Pokémon is returned and that's it for that day. I need one Pokémon to guard a gym for 10 hours to get the max. I am also wondering what that 50 coin/day limit for guarding a gym is about. The hold for gifts is anyway limited to 10, when you have maxed out your friends list, it is nearly impossible to exchange gifts on a daily basis unless you upgrade your bag to hold 1500 items, because you have to open the gifts, get up to 8 items and spin a lot of stops to get gifts you can pass on to your friends. During lunch I can walk past there and spin the stops and if I am lucky I get every third or fourth time a gift. The American Embassy for instance has two! Pokestops. I live in a big city and like to give my friends gifts with some meaning to their country (well, I reduced that ambitious goal to once a month or so), e.g. Also what's the deal with some stops giving you gifts 10 times in a row and others never. When I need gifts, well I guess you know by now that whenever I spin the stops and gyms, I don't get gifts. When I needed berries or balls, I got potions. When I needed potions, I got all kinds of balls, but never potions. I have anyway the feeling that you very rarely get what you need. Never mind "Sunkern", never encountered one either. I mean 100 Candy is a lot, especially when you never encounter the Pokémons. And even worse on Level 3 on "A ripple in time" because I have not encountered "Oddish" or "Gloom" to get enough candy to evolve the one I have already. I am stuck on "A mythical discovery" on level 5 for months because I don't get a "Ditto". +++ UPDATE +++ I've got my Ditto! Yeah! Just right before the new year starts! A measly 10 CP Zigzagoon was its disguise, but who cares! Finally progress on the Research. |
