  • Them bones do more than you give them credit for. (Camilo Jimenez via Unsplash/) In a stressful situation, your hands may sweat and your heart may pound. But a new paper published Thursday in Cell Metabolism suggests that a less obvious organ—your skeletal system—is what starts the fight-or-flight response that gets you out of harm’s way. “It’s a revolutionary study,” says Ernestina Schipani, a medical doctor and professor of orthopaedic science at the University of Michigan who was not involved in the new research. The paper, she says, completely changes our understanding of the sympathetic nervous system—the “fight-or-flight” response—by demonstrating that bone is “critically important” to its function. Until now, Schipani says, she and the rest of the scientific community thought it was adrenaline, a well-known hormone produced by the adrenal glands located above the kidneys, that kickstarted fight-or-flight. But according to this new research in lab mice, an acute stress response is impossible without a hormone called osteocalcin—which, as its name suggests, is made by bones. Julian Berger, a genetics PhD candidate at Columbia University and the study’s first author, says that when his team inhibited osteocalcin production in mice and then exposed them to a stressor, like the odor of fox urine, they didn’t seem appropriately fazed. “It’s almost like someone is mugging you and you ignore them and take out a Snickers bar,” he says. If you’re surprised that bones can produce a hormone that impacts the nervous system, you’re not alone. Little more than a decade ago, scientists thought that bones were pretty much exactly what they look like at first glance: hollow tubes made of calcium designed to hold the rest of our bodies up. But as this new study demonstrates, our skeletons can actually change the way we react to the world around us....
  • If you cherish your jeans, you want to keep them wearable as long as possible. (Ricardo Gomez Angel via Unsplash/) There’s a particular sick stomach lurch that happens when you rip a favorite pair of jeans, not unlike the feeling of losing a beloved pet or fumbling a fragile family heirloom. For many of us, the denim we live in becomes an inextricable part of our lives. But a tear doesn’t have to mean tears. In recent years, a handful of pros have gained online acclaim by showing that it’s possible to re-weave denim, thereby healing a rip instead of just patching it. “Pretty much anything can be fixed,” says Kattya Torres, owner of New York City-based Denim Therapy. Torres’ company has become famous among jean lovers for seamlessly repairing even the most dramatic rips. “It’s like a puzzle. I have had jeans come in here that look, honestly, like a g-string, and we’re able to reconstruct it.” While you may not want to attempt that level of denim surgery right away, it’s possible to pull off some smaller patch jobs from the comfort of your own home. Jean therapy for beginners “Denim is extremely forgiving. It hides a lot of imperfection,” Torres says. That’s good news for those of us without access to the signature Colour Match system pioneered by Denim Therapy, or the specialized industrial sewing machines touted by companies like San Francisco-based Self Edge. But if you’re willing to tolerate some imperfection, you can do a passable job with some basic supplies and a standard sewing machine (or, if you don’t have a sewing machine, with a lot of patience). Ripped knees and crotch blowouts are the two most common types of repairs Torres sees, and both are within reach of the home re-weaver. “The most important...
  • Small streams could be in danger (Joao Branco/Unsplash/) The Trump Administration just announced yet another blow to the country’s environmental protections. On Thursday, officials from the EPA and the U.S. Army Corps of Engineers repealed an Obama administration update to the 1972 Clean Water Act, which had expanded protection to wetlands and streams that are disconnected from navigable rivers. “They’re effectively sending us back 30 years in our protections of U.S. waters,” says Peter Gleick, co-founder of the Pacific Institute and a MacArthur “genius” Fellowship winner for his work as a climate and water scientist. The 2015 rule has broadened the definition of “waters of the United States,” which allowed the EPA to regulate pollutants in a much greater proportion of waterways than before. Dry washes and streams may only flow intermittently, but according to an EPA report they make up about 59 percent of streams in the U.S. and 81 percent of those in the Southwest. Another EPA report, which supported the 2015 rule, reviewed more than 1,200 studies on small streams and wetlands and found that they’re critical to the health of downstream rivers: “There is ample evidence that many wetlands and open waters located outside of riparian areas and floodplains, even when lacking surface water connections, provide physical, chemical, and biological functions that could affect the integrity of downstream waters.” And yet, many of these waters now have no protection under federal law. The original definition of “waters of the United States” mainly covered large rivers, their tributaries, and adjacent wetlands. The Clean Water Act requires industrial and municipal polluters discharging to these rivers to obtain permits from the EPA and the 2015 update expanded those regulations to include smaller streams and wetlands. Thursday’s repeal will soon be followed by a rule change, and the replacement text...
  • Recovery efforts on these northern Bahamian islands have only just begun, and many small villages have not yet received aid, according to the Associated Press. Dorian’s 180 mph sustained winds caused an estimated $7 billion of damage. The storm killed dozens, and search and rescue teams are still looking for approximately 1,300 missing people. Officials expect the death toll to rise. 10 minutes mail – Also known by names like : 10minemail, 10minutemail, 10mins email, mail 10 minutes, 10 minute e-mail, 10min mail, 10minute email or 10 minute temporary email. 10 minute email address is a disposable temporary email that self-destructed after a 10 minutes. https://tempemail.co/– is most advanced throwaway email service that helps you avoid spam and stay safe.

  • An artistic representation of the exoplanet K2-18b. (Alex Boersma/) If you could pack a hot air balloon onto an interstellar spaceship and travel 110 light years to a certain planet orbiting a dim star in the constellation Leo, you’d have an experience not entirely unlike ballooning on Earth. The temperature, pressure, and moist air could feel quite pleasant, though you’d need an oxygen mask—and possibly an umbrella. “It could happen that you get rained upon,” says Björn Benneke, an exoplanet researcher at the University of Montreal. Telescopes hunting for flickering, wobbling stars have located more than 4,000 potential exoplanets in recent decades, some of which orbit in the not-too-cold, not-too-hot zone around their host star where water would have a shot at staying liquid. Others have even been found to harbor actual molecules of H2O. The exoplanet K2-18b, however, is the first to check both boxes, according to two studies published this week. Unfortunately, a few other decidedly unearth-like characteristics make K2018b an improbable home for life as we know it. But the discovery represents an important step toward finding planets we might actually consider hospitable. “It’s the closest we have come to detecting some kind of environment similar to the Earth,” says Benneke, who leads one of the two teams studying the planet. Everything scientists know about this alien world comes from the way it interacts with its star. The Kepler mission first spotted the star’s dimming in 2015, and follow-up observations with the Spitzer space telescope confirmed presence of a planet twice as large as Earth in 2017. A different instrument then weighed the planet by measuring the star’s wobble, finding it to be about eight times heavier than Earth. Another three years of observations with the Hubble Space Telescope managed to capture eight more flickers of light,...
  • This easy-to-use, non-stick wok is a great way to test your aptitude for stir-fry if you’re a beginner cook (or just beginning to try Chinese cooking). It’s dishwasher and oven safe, made out of lightweight aluminum with a non-stick coating, and can be used for regular forms of sautéing, simmering, or poaching. Please note: Non-stick pans won’t be as durable as our other options, and won’t stand up to very high heat. If your favorite Chinese dishes are sauce heavy Americanized staples like General Tso’s Chicken, this will work fine. Otherwise, save up for carbon steel or a cast iron wok. 10 minutes mail – Also known by names like : 10minemail, 10minutemail, 10mins email, mail 10 minutes, 10 minute e-mail, 10min mail, 10minute email or 10 minute temporary email. 10 minute email address is a disposable temporary email that self-destructed after a 10 minutes. https://tempemail.co/– is most advanced throwaway email service that helps you avoid spam and stay safe.

  • A movement is building to define suicidality as a condition in its own right. (Noah Silliman/Unsplash/) One night in her Nashville apartment, Bre Banks read a comment from her boyfriend on Facebook. They were in a shaky spell, and his words seemed proof she would lose him. She put her laptop down on the couch and headed to the bedroom to cry. “My legs seized up, and I fell,” she recalled. With her knees and forehead pressing into the carpet, she heard a voice that said, “Slit your wrists, slit your wrists.” She saw herself in the bathtub with the blood flowing. She was terrified that if she moved she would die. Banks, then 25, was a disciplined graduate student with a job and close friends and had no psychiatric history. “I had never considered suicide an option,” she says. But for the next three days, she couldn’t sleep while the voice and disturbing images persisted. After seeing a therapist, she decided to teach herself techniques from dialectical behavior therapy, one of the few treatments shown to reduce suicidality. The voices and images came back over the next few months, but eventually faded. Eight years later, Banks now evaluates suicide prevention programs across Tennessee as a manager at the large mental health provider Centerstone’s research institute, and she and the same boyfriend just celebrated their 10th anniversary. In the public imagination, suicide is often understood as the end of a torturous decline caused by depression or another mental illness. But clinicians and researchers know that suicidal crises frequently come on rapidly, escalating from impulse to action within a day, hours, or just minutes. Many also point to the fact that they may strike people like Banks, who are otherwise in good mental health. That understanding is one reason a movement...
  • Sleep aids to stay rested. (Kinga Cichewicz via Unsplash/) Today’s culture is all about the ‘sleep when you’re dead’ mentality, even if it means sacrificing our wellbeing. Luckily, the tide has shifted back to the need for healthy, quality rest, and has put an emphasis on how important sleep is for functioning productively and creatively. This has created a wealth of gadgets and tech to help us get the sound sleep we deserve. Here are our top picks for sleep aids that we dream of: Sleep like you’re being coddled with a warm hug. (Amazon/) Weighted gravity blankets have proved to be an answer to an insomniac’s prayers by providing the perfect amount of pressure to help anyone fall asleep. Made from high-quality Egyptian cotton, this one also features box stitching to ensure an even weight, and you can choose between 15, 20, and 25 pounds. It’s like sleeping in a hug, without having to deal with a person fidgeting next to you. The best way to improve your sleep habits is to understand them. (Amazon/) The next best thing to having scientists monitor and track your sleep: this one-time installation sleep tracking pad from the French brand Withings. Pair it with your iPhone, Android, or Alexa to learn about your sleep cycles and heart rate throughout the night. It can also detect snoring and any breathing disturbances, which is useful to determine if you have a sleep condition like sleep apnea. You’ll get a daily “sleep score,” which makes trying to improve your sleep with the in-app coach a fun game. A very goofy-looking but effective snoring solution. (Amazon/) If you or your partner is a chronic snorer, then you’re likely familiar with the predicament of sleeping next to an unwitting noise machine at night. This chin strap is...
