Scientists at <a href="http://www.hopkinsmedicine.org/som/">Johns Hopkins Medicine</a> are trying to bring a level of objectivity into the search for those at high risk of attempting suicide &#8211; in the form of a simple blood test.http://www.popsci.com.au/science/medicine/blood-test-could-detect-a-genetic-tendency-toward-suicide,390490Wed, 30 Jul 2014 19:53:48 +1000Crazy Ukrainians Experiment with MicrowavesTaking apart a microwave and building your own ray gun is a bad idea.

We were immediately giddy, imagining&#160;the endless possibilities of being able to&#160;upload any design and, in Amazon fashion,&#160;have it shipped to us in solid form overnight. But the online book purveyor that has diversified to sell basically everything on the planet&#160;seems to have squandered its opportunity to transform the 3-D printing movement; the products in its new online marketplace are not customizable, fairly expensive, and slow to be delivered.&#160;http://www.popsci.com.au/gadgets/amazons-new-store-for-3dprinted-products-omits-the-best-parts-of-3d-printing,390445Wed, 30 Jul 2014 08:40:25 +1000Laser Light Could Make Flu Vaccine 7 Times More EffectiveWhen you get a vaccine, it's typically injected into the muscle below the skin with&#160;a needle. But vaccines administered through the skin can use smaller pin-prick methods that could be useful for those afraid of needles, such as children. These cutaneous vaccines have the <a href="http://www.ncbi.nlm.nih.gov/pubmed/24521050">potential to be relatively painless</a>, and could also possibly require less vaccine material. Unfortunately, the chemical <a href="http://www.cdc.gov/vaccinesafety/concerns/adjuvants.html">adjuvants</a> used in intramuscular vaccines can cause scarring and ulceration, and therefore new adjuvants for cutaneous (skin-administered)&#160;vaccines are "urgently needed," <a href="http://www.ncbi.nlm.nih.gov/pubmed/24521050">as various researchers</a> <a href="http://www.jimmunol.org/cgi/content/meeting_abstract/188/1_MeetingAbstracts/113.29">have written</a>.&#160;Adjuvants are chemicals like aluminum salts and oils which work by mimicking components of pathogens (like bacterial cell walls) that the immune system has evolved to recognized and react to.&#160;http://www.popsci.com.au/science/medicine/laser-light-could-make-flu-vaccine-7-times-more-effective,390444Wed, 30 Jul 2014 08:40:23 +1000Pest In Brazil Has Evolved Resistance Against GMO CornCrop-munching caterpillars in Brazil are no longer put off by genetically modified plants designed to kill them, <a href="http://in.reuters.com/article/2014/07/28/brazil-corn-pests-idINL2N0Q327P20140728">Reuters reports</a>.

Over the past decade, most citizens&#8217; ideology has gradually stretched to accommodate the need for birth control, but emergency contraception (AKA the &#8220;morning after&#8221; pill) is still highly controversial in Peru. Although some question the pill on moral grounds, others are starting to question it based on sinister scientific findings: some of the pills are not <em>the</em> pill.http://www.popsci.com.au/science/medicine/the-fight-against-fake-birth-control,390399Tue, 29 Jul 2014 07:17:33 +1000Behind The Scenes Of &#8220;The Whole Brilliant Enterprise&#8221;For the July issue of <em>Popular Science</em>, we&#8212;the <a href="http://www.o-c-r.org">Office for Creative Research</a>&#8212;created&#160;<a href="http://www.popsci.com/article/science/whole-brilliant-enterprise-nasa%E2%80%99s-first-50-years-one-interactive-graphic">a data visualization</a> celebrating NASA&#8217;s long history of aerospace innovation.&#160;Since 1959, NASA has published&#160;a document called &#8220;<a href="http://history.nasa.gov/timeline.html">Astronautics &amp; Aeronautics Chronology</a>&#8221; nearly every year,&#160;compiling&#160;news coverage of science, technology, and policy at the agency. In these compilations, NASA is reporting its own history. What kinds of stories do these documents hold? How has their language changed over the last six decades? To explore these questions, we created &#8220;The Whole Brilliant Enterprise,&#8221;&#160;a text-based visualization drawn from&#8212;by our count&#8212;4,861,706&#160;words&#160;of NASA&#160;history.http://www.popsci.com.au/space/behind-the-scenes-of-8220the-whole-brilliant-enterprise8221,390397Tue, 29 Jul 2014 07:17:30 +1000The Whole Brilliant Enterprise: NASA&#8217;s First 50 Years In One Interactive Graphic<strong>Ever since</strong> NASA established its history program in 1959, the agency has periodically compiled the world&#8217;s aeronautics advances into a single report. Assembled mostly from press releases and news stories, the documents recount coverage of budget negotiations alongside milestones like the shuttle program and the moon landing. Data illustrators at the <a href="http://o-c-r.org/">Office for Creative Research</a> distilled the trove of reports from 11,000 pages and 4.9 million words into just over 4,000 discrete phrases. Their illustration charts the frequency of some of the most important terms, colored by topic and arranged by time, and presents a new view of how NASA took humanity to the stars.http://www.popsci.com.au/space/the-whole-brilliant-enterprise-nasa8217s-first-50-years-in-one-interactive-graphic,390398Tue, 29 Jul 2014 07:17:00 +1000Smart Seatbelts Detect Drowsy DriversWhat if your car could sense when you were falling asleep behind the wheel, and wake you up before you caused an accident?

The bottom image shows each cell in a different color, with lines to show how those cells moved around.http://www.popsci.com.au/science/nature/how-to-watch-an-animal-develop-cell-by-cell,390198Wed, 23 Jul 2014 07:32:44 +1000MERS Virus May Be Able To Spread Through The AirResearch strongly suggests that camels carry Middle East Respiratory Syndrome (MERS), a viral illness that has sickened nearly 700 and killed at least 209 people as of early June, according to the <a href="http://www.who.int/csr/disease/coronavirus_infections/MERS-CoV_summary_update_20140611.pdf?ua=1">latest update&#160;from the World Health Organization</a>. For this reason, the government of Saudi Arabia recently warned people to stay away from close contact with camels, at least those that appear to be sick, which prompted some to defiantly <a href="http://www.popsci.com/article/science/why-people-are-kissing-camels-social-media">post photos of themselves kissing camels</a> on various social media sites.http://www.popsci.com.au/science/medicine/mers-virus-may-be-able-to-spread-through-the-air,390197Wed, 23 Jul 2014 07:32:41 +1000How Climate Science Gets Done In The Icy Fjords of GreenlandDo you wonder what doing climate science in remote locations might be like? Read the <a href="http://blogs.ei.columbia.edu/tag/greenland-thaw/" target="_blank">Greenland Thaw blog,</a> which is being updated regularly from the fjords of northwest Greenland, where the giant island's glaciers meet the ocean. With Greenland's ice sheets melting faster than ever, the study's scientists want to document and understand why the Alison Glacier, on Greenland&#8217;s northwestern coast, is flowing to the sea faster than other glaciers in the area.http://www.popsci.com.au/science/how-climate-science-gets-done-in-the-icy-fjords-of-greenland,390196Wed, 23 Jul 2014 07:32:38 +1000Ask Anything: Could Scientists Put Sunscreen In A Pill?Turns out, a few oral sunscreens already exist, based on the theory that antioxidants offer sun protection. Laboratory studies provide some evidence in support of this idea. When scientists feed vitamin E to hairless mice, the animals show less skin damage upon&#160;exposure to ultraviolet light. Dermatologist Salvador Gonz&#225;lez Rodr&#237;guez has studied an extract made from a fern called Polypodium leucotomos. The substance, which is high in antioxidants, may decrease sun-related DNA damage in humans, he says. But as a consultant for a Spanish company that makes an oral sunscreen, Rodr&#237;guez has skin in the game, so to speak. And he admits that oral sunscreens don&#8217;t work that well when measured in the standard ways: &#8220;If we evaluate protection in terms of how conventional&#160;sunscreens are evaluated, then antioxidant-based oral sunscreens provide very low SPF.&#8221;http://www.popsci.com.au/science/ask-anything-could-scientists-put-sunscreen-in-a-pill,390164Tue, 22 Jul 2014 08:02:17 +1000The Science of LightningWhen it comes to thunderheads, lightning is the great equalizer. Essentially a giant spark, lightning relieves the charge differentials that build up in storm systems. But it&#8217;s also one of the greatest mysteries in atmospheric science. Recently, scientists have started to explore lightning&#8217;s lesser-known siblings, which appear in ash plumes, labs, and even on other planets.http://www.popsci.com.au/science/nature/the-science-of-lightning,390163Tue, 22 Jul 2014 08:02:15 +1000Squid Protein Could Help Brains 'Talk' to ComputersIn the most advanced prosthetics--such as this crazy&#160;<a href="http://www.popsci.com/technology/article/2012-12/brain-machine-interface-breakthroughs-enable-most-lifelike-mind-controlled-prosthetic-arm">mind-controlled robotic arm</a>--electronic hardware&#160;interfaces directly with&#160;nerves and muscles in the human body.

These little pyramids are actually microscopic traps designed to gently enclose single cells without killing them. The idea is that in the future, such traps could be a part of a system for capturing and analyzing individual cells, perhaps as a part of cancer monitoring.http://www.popsci.com.au/science/medicine/tiny-traps-capture-individual-blood-cells,390161Tue, 22 Jul 2014 08:02:13 +1000Ask Anything: Can Humans Smell Fear?If humans can indeed smell fear they wouldn&#8217;t be unusual in the animal kingdom. Sea anemones, earthworms, minnows, fruit flies, rats, mice, and deer, among others, have all been shown to signal unease through odor. Some responses are even more overt. For&#160;example, the offspring of one bird species vomits up a pungent, orange liquid when frightened by a predator; if a parent catches a whiff, it becomes warier in the nest.&#160;http://www.popsci.com.au/science/ask-anything-can-humans-smell-fear,390160Tue, 22 Jul 2014 08:02:12 +1000Welcome To The Lab Of An Apollo Computer AnatomistFran Blanche&#8217;s workshop is more than a place to unwind. It&#8217;s home. &#8220;I put a bed in my office,&#8221; she says. Her fashion business is downstairs; upstairs is a music studio and a laboratory with 30 years&#8217; worth of tools. A private collector recently asked Blanche&#160;to study part of his Apollo-era <a href="http://www.frantone.com/designwritings/design_writings_LVDC.html">Launch Vehicle Digital Computer</a> (LVDC), which NASA designed to fly a Saturn V rocket. &#8220;All modern boards would come to emulate it,&#8221; Blanche says. &#8220;Trouble is, there&#8217;s no information about how it was constructed.&#8221;&#160;http://www.popsci.com.au/make/welcome-to-the-lab-of-an-apollo-computer-anatomist,390159Tue, 22 Jul 2014 08:02:10 +1000Woman Grows A Nose On Her Spine After Stem Cell ExperimentEight years ago, doctors took nasal tissue samples and grafted them onto the spines of 20 quadriplegics. The idea was that stem cells within the nasal tissue might turn into neurons that could help repair the damaged spinal cord, and <a href="http://nnr.sagepub.com/content/24/1/10">the experiment</a> actually worked a few of the patients, who regained a little bit of sensation. But it didn&#8217;t go well for one woman in particular, who not only didn&#8217;t experience any abatement in her paralysis, but recently started feeling pain at the site of the implant. When doctors took a closer look, they realized she was growing the beginnings of a nose on her spine, <em><a href="http://www.newscientist.com/article/dn25859-stem-cell-treatment-causes-nasal-growth-in-womans-back.html">New Scientist</a></em> reports.http://www.popsci.com.au/science/medicine/woman-grows-a-nose-on-her-spine-after-stem-cell-experiment,390103Sat, 19 Jul 2014 21:31:31 +1000The Week In Drones: Wedding Photographers, Prison Guards, And MoreHere's a roundup of the week's top drone news, designed to capture the military, commercial, non-profit, and recreational applications of unmanned aircraft.http://www.popsci.com.au/robots/drones/the-week-in-drones-wedding-photographers-prison-guards-and-more,390102Sat, 19 Jul 2014 21:31:29 +1000
