The U.S. Army tallied 38 confirmed or suspected suicides among its ranks last month--that’s among both active- and non-active-duty members including the Army National Guard and Army Reserve--the highest rate of suicide within the branch yet observed, further underscoring a mental health crisis that the services have yet to get a handle on. But help may be coming in an unlikely form: nasal spray.
Massive blood loss, known as MBL in the medical world, is a major cause of death during cardiac surgery--and an accepted one, because it's the best option we have. Blood transfusions help, but those aren't without complications, either. A new device could cut that step out of the process for some patients by collecting the blood from a surgery, concentrating the blood cells, and routing it intravenously right back to the person on the table.
Billionaire Peter Thiel would like to introduce you to the other, other white meat. The investor’s philanthropic Thiel Foundation’s Breakout Labs is offering up a six-figure grant (between $250,00 and $350,000, though representatives wouldn’t say exactly) to a Missouri-based startup called Modern Meadow that is flipping 3-D bio-printing technology originally aimed at the regenerative medicine market into a means to produce 3-D printed meat.
Neurodegenerative diseases like Parkinson's, Alzheimer's, or Creutzfeld-Jacobs are tough to diagnose. Outward symptoms can obviously be an indicator, but symptoms for many neuro-disorders overlap while protein biomarkers for each illness, called amyloids, are difficult to distinguish between.
The first serious indications of the ecosystem impact of the Fukushima nuclear disaster in Japan are in, and they're troubling. Researchers there collected 144 common pale grass blue butterflies from the region a couple of months after the catastrophic nuclear meltdowns leaked radiation into the environment last year. After studying them for a few generations, those researchers are finding signs of genetic mutations that are leading to physical abnormalities.
A simple blood test that offers early detection of cancer in the human body has long eluded medical researchers, but a team at UCLA is getting closer. By blending an ultra-fast camera and a powerful optical microscope with software that can process the data they produce at extremely high speeds, the team hopes it can spot circulating tumor cells (CTCs) that have broken away from cancerous tumors in blood samples, potentially making early cancer detection as simple as taking a blood draw.

No one can accuse our colleagues from PopSci's past of not trying. They devoted a large section to tips (with illustrations!) to staying healthy, with assistance from science. Some of those tips, like warnings about diet pills, could be printed today and no one would bat an eye--but others, like chores being enough exercise for "a housewife," maybe not so much. Check out the gallery for them all.
It's widely assumed that training on top of a mountain will give an athlete a major leg-up when competing closer to sea level. But it turns out it's not quite that simple, and in fact, athletes are discouraged from conducting training exclusively at high altitudes. How much altitude training helps, and how to tweak the finer points of a high-altitude training regimen are questions still under consideration. It's not nearly as simple as running on a mountain, coming down, and feeling prepped for your marathon.
What you might not expect when you’re expecting: a company that wants to 3-D print a statuette of your unborn child. Japanese engineering outfit Fasotec will gladly take an MRI scan of an expecting mother’s fetus and using its BioTexture modeling software to capture 3-D data related to human tissues convert that scan into a CAD file, then print it up in resin. It’s called the “Shape of Angel” service (what else?), and it will only set you back roughly $1,250.
The day I entered public school, I was classified as visually impaired. I have a rare genetic syndrome known as achromatopsia. I'm color blind and light sensitive, and my distance vision is flat-out awful. Even corrected, it's closer to 20/100 than 20/20. I can't see street signs until I'm a yard away from them and I don't even bother trying to read most posters, plaques or museum cards.
I'm not alone: About 21.5 million Americans have low vision, and analysts expect that number to double over the next 30 years as baby boomers age. But new uses for near field communication (NFC), a short-range device-to-device transmission protocol, could help break down the frustrating barrier between the visually impaired and the text around them.
