    A teen has reportedly died after getting a love bite from his girlfriend that caused him to have a stroke . Julio Macias Gonzalez started having convulsions at the dinner table with his family in Mexico City after spending an evening with his girlfriend. Paramedics were dispatched to the scene but the 17-year-old could not be saved. It is thought that the suction of the love bite – also known as a ‘hickey’ – caused a blood clot that travelled to Julio’s brain and caused him to have a stroke. His 24-year-old girlfriend has now disappeared and the boy’s parents...

    In cooperation with the Sinapore University of Technology and Design, the MIT researchers found a way to print tiny features on a micron scale, and then bent them — causing them to spring back into their original shape afterwards after being heated to a certain temperatures, according to an MIT statement. There are so many potential important applications for the discovery, including actuators that would turn solar panels toward the sun automatically and drug capsules that act on their own. It’s something that goes beyond 3D printing into what researchers would call 4D printing, as the structures cross into the...

    “These misconceptions or behaviors that work in Latin America but don’t work here because buildings are different here, earthquakes are different here,” says Pablo Ampuero, professor of seismology at Caltech. It’s the first time Caltech has hosted an event like this, where the community engaged directly with scientists and experts, asking questions and getting important answers. The event stressed the importance of being prepared for disaster. And how earthquakes here in the US are different from those in other parts of the world. “When you look at what the earthquake will do to us, it probably won’t kill us, but...

    As people move through a space with a Wi-Fi signal, their bodies affect it, absorbing some waves and reflecting others in various directions. By analyzing the exact ways that a Wi-Fi signal is altered when a human moves through it, researchers can “see” what someone writes with their finger in the air, identify a particular person by the way that they walk, and even read a person’s lips with startling accuracy—in some cases even if a router isn’t in the same room as the person performing the actions.

    Within 24 hours the patient's responses had improved and in just three days he was fully conscious and had fist-bumped a doctor. Doctors have woken a coma patient for the first time ever by jump-starting his brain using a pioneering ultrasound technique. A saucer-sized device was put against the side of the 25-year-old patient’s head over a 10 minute period. Each of the 10 half-minute, low-intensity pulses created acoustic energy to stimulate brain tissue. The patient’s responses improved measurably within 24 hours. In three days he was fully conscious and had complete language comprehension. He could nod his head “yes”...

    These findings indicate that fat cells in obese people do something different than in healthy peopleA new study finds striking metabolic differences between fat cells from obese and normal weight people—but it’s not clear what the findings mean to overall health. WHY IT MATTERS: Obesity is associated with complications like diabetes and heart disease. But over the past 15 years, evidence has emerged that a subgroup of obese people are metabolically healthy, meaning they don’t have the insulin resistance, high blood sugar, high cholesterol, and high triglycerides typical of obesity. That has led to questions of whether treating the obesity...

    WWith hindsight, it seems as though scientific breakthroughs sweep quickly to universal acceptance. A paper is published and everybody says, “Eureka!” But that’s not necessarily the case. Sometimes scientists have too much invested in the status quo to accept a new way of looking at things. This was certainly true when Albert Einstein‘s 1905 paper on “special relativity” first challenged the British conception of ether. Einstein argued that space and time were bound up together (something he would elaborate on in his theory of general relativity of 1915, adding gravity to the mix of space/time), a complicated idea that contradicted...

While Zika is spread primarily through the bite of the black-and-white-striped Aedes mosquito, the virus also can be passed through sex, health officials said. They are mostly concerned with people returning home from the Olympics in Rio de Janeiro, because Brazil has been hit hard by the virus. “Continue using insect repellent to...

And while there have been some hints of “proving Einstein wrong,” nothing has really stuck. But even so, scientific “fact” is a fact only...

So why is the night sky not completely lit up by the light from these stars? This question was first asked by the nineteenth century astronomer Heinrich Olbers, and the answer is, because of the age of the universe, not all of the photons have had enough time to reach us yet. The amount of universe we are able to see is called the observable universe, and according to a pair of astrophysicists, it just got...

    Steinhauer created a sonic black hole using a quantum state of supercold fluid called a Bose-Einstein condensate. The fluid flows through a tube in which lasers constrain the flow at two different energy levels, creating a kind of waterfall. Atoms reach supersonic speeds when they spill over its edge. This serves as the model event horizon. To measure Hawking radiation, he pinged the fluid with a short laser pulse. This created a sound particle known as a phonon, along with a partner particle, near the horizon – just as Hawking suggested happens near a real black hole. He then took...

    Did you know there is an International Journal for Philosophy of Chemistry? Neither did I, but of course it exists, for there really is no crazy identity politics “intersection” that doesn’t have its own journal read by dozens. The IJPC recently offered up a two-part article on “Gender in the Substance of Chemistry,” by Agnes Kovacs, who you will be unsurprised to learn is a professor of gender studies at Central European University in Hungary. Part 1 considers “the ideal gas,” which will certainly prompt a number of obvious suggestions from our regular commenters:

    President Barack Obama picked one of the hottest weekends in the Northeastern U.S. to discuss climate change. “One of the most urgent challenges of our time is climate change,” the vacationing president said in his Saturday radio address. He touted his efforts to cut pollution, including from cars and trucks, assuring Americans, “we’re not done yet.” Obama announced that before he leaves office, “We’ll release a second round of fuel efficiency standards for heavy-duty vehicles. We’ll take steps to meet the goal we set with Canada and Mexico to achieve 50 percent clean power across North America by 2025. And...

  • Nissan revolution: could new petrol engine make diesel obsolete?

    ATSUGI, JAPAN -- Japanese automaker Nissan Motor Co has come up with a new type of gasoline engine it says may make some of today's advanced diesel engines obsolete. The new engine uses variable compression technology, which Nissan engineers say allows it at any given moment to choose an optimal compression ratio for combustion - a key factor in the trade-off between power and efficiency in all gasoline-fuelled engines. The technology gives the new engine the performance of turbo-charged gasoline engines while matching the power and fuel economy of today's diesel and hybrid powertrains - a level of performance and...

    For a 2-billion-year-long span, ending about 715 million years ago, Venus was likely a much more pleasant spot that it is today. To observe Venus now is to witness a dry and toxic hellscape, where the planet heats up to a scorching 864 degrees Fahrenheit. A super-strong electric wind is believed to suck the smallest traces of water into space. With apologies to Ian Malcolm, life as we know it could not find a way. But travel back in time a few billion years or so. Ancient Venus, according to a new computer model from NASA, would have been prime...
  • How is Ammonium chloride different that mixing ammonia and chlorine?

    08/13/2016 10:53:00 AM PDT · by rey · 33 replies
    I know never to mix cleaners and to certainly never mix ammonia and chlorine but many cleaners contain ammonium chloride. Is this not essentially ammonia and chlorine? If not, how does it differ? If it is similar, what is done to it so it doesn't kill the user? I am obviously not a chemist and have merely an nodding acquaintance with the periodic table, so I would ask that your explanations be simplified as much as possible, as Einstein said, "As simple as possible but no simpler." Thanks

    Science ^ | 8/8/2016 | Julius Nielsen
    We tend to think of vertebrates as living about as long as we do, give or take 50 to 100 years. Marine species are likely to be very long-lived, but determining their age is particularly difficult. Nielsen et al. used the pulse of carbon-14 produced by nuclear tests in the 1950s—specifically, its incorporation into the eye during development—to determine the age of Greenland sharks. This species is large yet slow-growing. The oldest of the animals that they sampled had lived for nearly 400 years, and they conclude that the species reaches maturity at about 150 years of age. The Greenland...

    It is likely that on the night of Saturday, Aug. 20, in the Olympic Stadium in Rio de Janeiro, a 25-year-old South African woman named Caster Semenya will win a gold medal. Her victory will come in the 800 meters, a race in which her times have been approaching a decades-old world record thought by many in the sport to be unapproachable. Her performance will be stunning: She is 5'10" and weighs 161 pounds, with muscular arms, broad shoulders and narrow hips. She has a severe jawline, hard and strong, and a competitor's unflinching eyes. In a 2009 article, Ariel...
