For a more targeted microbiome fix than a fecal transplant.
The gut microbiome-the trillions of bacteria that live in the intestines-is integral to health. Those microbes help digest food, affect immune systems, and can alter body weight or even mood. The problem is that microbiomes vary so much that scientists often don't know just what has thrown it out of whack. That's why some of the most hardcore have turned to fecal transplants, as a total microbial makeover.
Camping is a celebration of the primitive. It is the trading of convenience for spare simplicity; the swapping of modern routine for outdoorsy challenge. It's also just… not everyone's cup of tea. Yet many will go, determined to try and find the wonder and richness that their friends keep posting about on their Facebook feeds. The camping industry is growing after years of decline. A report says nearly one in three Americans went camping last year, and people from more than 1 million households camped for the first time. Nearly half of them were millennials between 18 and 35 years old.
This is going to sound like the tech-nerd version of one of those first-person People magazine essays about surviving adversity: You don’t appreciate how much you need to see your hands until you can’t.
Your hands – they’re always there. Even in the most immersive of media experiences — an IMAX movie or the hypnotic reverie of a darkened opera house — your sense of where your hands are is an ever-present comfort. Because you can see your hands, you can reach for the popcorn without knocking it over. Because your eyes aren’t locked on the screen, you can check your phone to make sure your babysitter hasn’t texted with an emergency.
The workplace of the future may be a far cry from the desk-driven, eight-hour-a-day jobs that defined corporate America for much of the 20th century. At least, that's what workers believe. A majority of 1,385 U.S. employees who were polled in a new survey by PricewaterhouseCoopers said they believe the eight-hour workday will become obsolete, while 68 percent said they believe work will be done outside a traditional office.
Researchers in Boston have discovered that not all light is created equal. People who experience migraines that are made worse by light might be better off seeing the world in green. While white, blue, red and amber light all increase migraine pain, low-intensity green light seems to reduce it. The team behind the finding hope that specially developed sunglasses that screen out all wavelengths of light except green could help migraineurs. Many people experience sensitivity to light during a migraine. Photophobia, as it is known, can leave migraineurs resorting to sunglasses in well-lit rooms, or seeking the comfort of darkness.
Almost 1 in 5 women suffers from migraines, and a new study provides more evidence that estrogen levels may play a role. According to a new study, estrogen levels are likely to drop more rapidly in the days just before menstruation for women with a history of migraine than they do for women who do not have migraine. The findings showed that the women with a migraine history had a faster rate of estrogen, a sex hormone which, decline regardless of whether they had a migraine during that cycle or not.
A team of Harvard engineers has come up with a fun way to get kids hooked on coding. The possibilities seem endless: virtual realities that immerse students in remote habitats or historical eras; learners mastering skills and content through digital games; kids everywhere achieving basic fluency in code, as their forebears once had to learn cursive. Even as researchers invent new ways to use machines for learning, they realize that the culture of the classroom may itself need to advance, in tandem with technology—a difficult proposition, when bandwidth is already taken up by battles over high-stakes testing, budgets, and teacher tenure. The call to reexamine what teachers teach can bring renewed discussions of how. With tools like augmented reality, games, and coding, it’s possible to imagine a model of schooling that departs from its behaviorist past—creating a Ludic Education for a Ludic Age, promoting inquiry, collaboration, experimentation, and play. In this vision, teachers and students are partners in a joint venture. They open up the Teaching Machine to peer into its guts and gears—tinkering, failing, and trying again, to see what they can make of it together. The machines can return education to what it’s always been: a project that’s intrinsically human.
The New England Journal of Medicine is calling the affliction "transient smartphone 'blindness.' "They were looking at their smartphones and they just happened to have one eye covered because they were lying in bed," says Omar Mahroo, an ophthalmologist at Moorfields Eye Hospital in London and an author on the letter. Here's how it happens: Light makes the pigment in rod-shaped cells change shape, which changes the electrical current running to another set of cells, which determines how much of a chemical those cells release to nerve cells, which eventually pass the message on to the brain. After exposure to a bright light, it can take 40 minutes for that process to reset, after which a person can again see in the dark.
