    When former U.S. President Jimmy Carter announced that not only did he have melanoma, but that it had spread to his liver and brain, many people probably had the same thoughts: Isn’t melanoma skin cancer? And how do you get it on your brain?

    “People think, 'Oh, it's melanoma that's just skin cancer – you cut it out and you don't have to worry about it,'” says Dr. Tim Turnham, executive director of the Melanoma Research Foundation in Washington, D.C.

    “That thought has two implications: it isolates patients – often people diagnosed with melanoma feel people don't understand that they’re dealing with a life threatening illness because they think it's 'Cancer Lite' – but more significantly, it means that people don't understand the risks and don't take appropriate steps to alleviate those risks.”

    One of those risks is that melanoma can metastasize to other, more vulnerable, parts of the body.

    The arcologies of "Sim City 2000" may not be as far off from appearing in our city skylines as we think.

    A skyscraper design containing various natural landscapes within it, including a desert, a forest, a jungle and a glacier won first place in architecture magazine eVolo's design competition for 2015, presenting a vision of the future that's very similar to the futuristic buildings that players could build in the PC classic “Sim City 2000.” But for the designers of Essence – the name of the winning project – it was a case of two nearly identical ideas being generated entirely independently of one another.

    Sim City did not play any role in the design process. In fact, until today, we had no idea about the arcologies, which had appeared there. Definitely we'll need to extend our fields of interest in order to improve our flexibility, when it comes to architectural design,” says Jakub Pudo, a member of BOMP, the four-person Polish urban architecture collective behind the design.

  • It’s Wednesday: eat more kale because it’s a superfood and super good for you. It’s Thursday: put that kale away, it can cause problems like chronic fatigue and consuming it can be toxic to your health.

    Kale’s utter goodness or fearsome badness should be a fairly simple and straight-forward matter of science. But contrasting studies have both praised and condemned the leafy green.

    How is it possible for science to be wrong so often?

    University of British Columbia microbiologist Rosie Redfield believes that bad science has been around forever and it’s not a new phenomenon. But because of the Internet, when scientists do get their facts wrong, it’s simpler and faster to discover the errors.

    “With social media and with everything online, it’s a lot easier for find things and it’s easier for us to talk to each other,” Redfield said.

    Redfield was one of the main scientists who helped debunk a controversial scientific paper put out by NASA and the journal Science back in 2010. The paper

    You swear you felt it, that buzzing sensation in your pocket indicating your phone has gone off. Somebody out there needs you and you must respond. You go to reach for your phone and realize it’s not there, so what did you just feel? This phenomenon is known as Phantom Vibration Syndrome and its prevalence has increased as constant mobile connectivity has become the norm.

    People experiencing phantom sensations is not a new occurrence in the medical community as amputees have often felt what is known as the Phantom Limb. Despite the limb being removed from the body, the brain still feels as if it’s there and continues to send the signals it would have sent if the limb still existed.

    “So why is this happening with the phones?” says Dr. Alan Monavvari, Chief of Family Medicine at Markham-Stouffville Hospital and a family practitioner at Discovery Family Health. “Most people tend to have their phones very close to their body. People used to attach it to their waist, now it’s in your

    Recent global outrage over trophy hunting has showcased just how vicious of a predator humans can be. But now, new research released this week in the journal Science offers sobering scientific evidence that proves that humans are indeed a new kind of indiscriminate super-predator, the likes of which the planet has never seen before. And if we continue our killing tendencies, we will be irreparably impacting the sustainability of the worldwide food web and even changing the course of evolution for countless species.

    Humans are one very unique predator and its our high rates of predation on adult age classes of prey that sets in motion all sorts of ecological and evolutionary effects that eventually harm humanity, said co-author of the new study Chris Darimont, Hakai-Raincoast professor at the University of Victoria and science director with Raincoast Conservation in an interview with Yahoo Canada.

    There are two things about dementia most people would agree on. One is that the thought of losing all or part of your mind is terrifying. The other is it’s a disease of the elderly.

    The first is true, and getting truer. Dementia is taking hold in frightening new numbers.

    As for the second? New research shows dementia is beginning to take hold of people in their 40s.

    Colin Pritchard is a research professor in the faculty of health and social sciences at Bournemouth University in England. He is co-author of a new report – published in Surgical Neurology International – that charts some alarming new trends.

    “The research was actually stimulated by the fact that I had two friends dying from motor neuron disease,” Pritchard told Yahoo Canada.

    “The textbooks, ten years ago, said that occurs in one in 100,000 people. Now, they say one in 50,000.”

    Pritchard, who says he doesn’t know anywhere near 50,000 people, thought this was very unusual.

  • Millions of bobbing balls of plastic may help Los Angeles conserve its drinking water but even though Vancouver is in the midst of its own drought conditions, those nifty shade balls, which have been poured into a California reservoir to protect the quality of the system, remain a novelty and not an answer to the city’s water problems.

    “We are not at the point yet here in Canada where we would need to do that but absolutely this year’s drought has opened people’s minds to the realization that we need innovative ideas,” says Robert Haller, executive director of the Canadian Water and Wastewater Association, the non-profit national body representing the public sector in the industry.

    Toronto Water’s general manager Lou Di Gironimo told Yahoo Canada the city’s water supply is from Lake Ontario.

    “We have a series of small water storage reservoirs that are all covered. We do not use ‘shade balls’ on top of our water reservoirs.”

    Skywatchers are gearing up for one of natures best fireworks show as the Perseid meteor shower peaks late Wednesday night through Friday morning.

    And with the moon in its new phase, leaving behind perfectly dark skies, this annual astronomical event promises to put on a great performance, producing as many as 60 to 100 shooting stars per hour at peak times.

    The official peak of the shower is well timed for North American viewing, occurring between 9 pm EDT Wednesday through 10 am EDT Thursday. However the Perseids will continue to fall until Aug. 25, with each consecutive night seeing about half the number of shooting stars.

    As with most other annual meteor showers, the Perseids are formed from a giant cloud of particles in space, most of these space stones being no bigger than a grain of sand. Streams of this stuff float in space and are actually debris that has been shed from a passing comet.

    In the case of the Perseids this week, the meteors all once called comet Swift-Tuttle

    The hunt for a twin Earth is quickly gaining ground as scientists make a series of amazing announcements the past few weeks showcasing the discovery of the closest and most Earth-like planets along with a near twin of our solar system.

    Astronomers are excited by the new-found, yet familiar-looking planetary system some 200 light years away called HP 11915. The finding took researchers by surprise, since out of more than 1200 planetary systems discovered to date, not one could match our own solar system in terms of architecture. Most appear to sport large planets many times the mass of Earth close to their stars, whereas in our solar system the small rocky planets are in the inner regions, while the larger gas giants like Jupiter and Saturn are scattered much further out.

    At the heart of the new system is a sun-like star that hosts a gas giant planet astronomers believe is very much like our own Jupiter. The planet appears to orbit about the same distance as Jupiter, and scientists

    When you’re sick – or when your kid is sick – you want relief immediately. For many people, that means going to the doctor to get a prescription for antibiotics.

    It may surprise you to find out that doing so is often the wrong move. In the U.S., a recent study by the Centers for Disease Control and Prevention (CDC) found that 25 per cent of the general population is under the mistaken belief that antibiotics can treat a cold.

    What are antibiotics used for?

    Antibiotics kill bacteria and stop bacterial infections. They will help if you have strep throat, bladder and skin infections, and some ear infections, which are all caused by bacteria. Antibiotics will not cure viral infections such as the common cold or flu.

    Sometimes a lab test is needed to identify whether you have a bacterial or viral infection, says Maryse Durette of Health Canada.

    “We try to avoid antibiotics when we can,” says Hoda Mankal, a nurse practitioner at the Carlington Community Health Center in Ottawa and the
