Here’s how you test your intracranial pressure in space. First, you collect baseline samples of your blood, saliva, and urine, and take ultrasound images of the vessels in your heart, neck, head, and eyes, lining up the scanning device on black dots tattooed on your body before you left Earth. Then, you clamber into the Chibis, Russian for “lapwing,” a pair of hard, corrugated-rubber pants whose waist can be sealed. The pants suck: A vacuum imitates how gravity on Earth pulls blood, mucus, the water in cells, and cerebral and lymphatic fluids from our skulls to the bottom half of the body. In space, fluids won’t drain, and astronauts develop red, puffy faces and complain of congestion or pressure in their ears. There are worse effects, too: 40 percent of the astronauts who lived on the International Space Station suffered some sort of damage to their eyes, including optic disc edema, globe flattening, and folds in the choroid, the blood-filled layer between the … [Read more...] about Are Humans Fit for Space?

caption Erin Brockovich never drinks water straight from the tap. source AquaTru Erin Brockovich is a former legal clerk and clean-water advocate who was made famous by Julia Roberts’ Oscar-winning portrayal of her in the 2000 film that shares her name. Brockovich helped citizens of Hinkley, California fight California Pacific Gas and Electric (PG&E) after unsafe levels of the carcinogen Chromium 6 were found in their water. Brockovich told Business Insider that she’s “funny” about her own drinking water. She offered a few tips for how to determine if your tap water is safe to drink and what to do when it’s not. If tap water looks like the color of “light pee,” Erin Brockovich refuses to drink it.

Disinfection of public drinking water is one of the great public health success stories of the 20th century. In 1900, outbreaks of cholera and typhoid, both caused by waterborne bacteria, were common in American cities. In 1908, Jersey City, N.J., became the first U.S. city to routinely disinfect community water. Other cities and towns quickly followed, and by 1920, the typhoid rate in the United States had dropped by 66 percent.But that battle isn’t over. Around the world, more than 2 billion people lack reliable access to safe water (SN: 8/18/18, p. 14), and half a million people die each year from diarrhea caused by contaminated water, according to the World Health Organization.And in the United States, challenges remain. The management failures that caused the 2014 lead contamination crisis in Flint, Mich., were a wake-up call (SN: 3/19/16, p. 8), but Flint is hardly alone. Systems in other big cities are also falling short. In October, officials in Newark, N.J., scrambled to … [Read more...] about Do you know how your drinking water is treated?
I'll be forthright: Improving your ability to smell various aromas in a glass of wine is not a major concern for most people. Correcting your friends by saying, "That's not blackberry you're smelling, it's blackcurrant" is less likely to engender respect and more likely to guarantee your disinvitation from the next soirée. Smelling better—with your nose, not your bodily aromas—is ultimately a personal endeavor. The sole exception to this is in serious wine education, and for those who want to become wine nerds. There's also some layperson value to connecting aromas with wines: If you're preparing a dinner that includes mushrooms, green peppers, and bay leaves, someone appropriately trained might suggest that a Cabernet Franc, which echoes those aromas, could pair well with it. Enjoying and identifying wine revolves predominantly around your sense of smell. If you want to body-hack your way to a better one, try a wine aroma kit. The concept is pretty simple: Break the … [Read more...] about Want the Nose of a Sommelier? Try a Wine Aroma Kit
