Particles from tattoo needles may end up in your lymph nodes

Tattoo needles break down during procedures, sending small particles of nickel and chromium into the body. That potentially can lead to allergic responses, researchers found. But it’s not just that ink is capable of reaching the body’s lymph nodes, as researchers previously revealed. Tattoo needles – even new ones – also may be playing a role. Chromium and nickel particles break off from the tattoo needle during the procedure, according to a new study published by Particle and Fibre Toxicology. They then end up in the lymph nodes, potentially causing an allergic reaction. Tattoo needles typically are comprised of 6-to-8 percent nickel and 15-to-20 percent chromium, according to the study. Both metals are known to prompt a high rate of allergies among the general population.  Using high-powered microscopes, researchers examined 12 needles both before and after they were used.  All the needles showed abrasion after a single use. But they particularly wore down when using pigments containing titanium dioxide, a compound commonly found in white tattoo ink.  The findings build on a 2017 study that showed pigments leak from the location of the tattoo on a person’s b...

Here’s a collection of some of the most innovative products tha...

Achieving Zero Latency for Video and Audio Is a Zero-Sum Game

As an industry, we make a lot of justifications about why video isn’t delivered in a timely manner and at uncompressed quality. Many of these are reasonable, centering on network capacity or intermittency, the cost to scale out low-latency solutions, or even the limitation of off-the-shelf processors to handle 4K Ultra HD or high dynamic range (HDR) content in real time. But the issue is fundamentally deeper than any of those issues, going to the codecs themselves and the packaging and segmentation that’s sprung up around scalable streaming video, both of which add inherent latency. A few of us have been ranting about these latencies since the advent of HDS, HLS, and even DASH. The move toward OTT live streaming has brought these latencies—or synchronicities, as one industry colleague referred to the issue of latency at Streaming Media East 2019— to the forefront. To better address latency for streaming, let’s use this article to explore ways to deliver video and audio that absolutely, positively have to be there now (to paraphrase the once-popular Federal Express slogan). It’s not a theoretical exercise, as can be attested in conversations at trade shows like InfoComm, wh...

Insider Inc. receives a commission from our affiliate partners when you buy through our links, but our reporting and recommendations are always independent and objective. Through years of making family meals, baking for friends, and experimenting with recipes, I’ve used different types of cookware. I like using certain types of pots and pans for specific purposes — nonstick aluminum for making omelets, stainless steel for boiling liquids and sautéing hash browns, and cast iron for searing steaks and stir-frying vegetables. It’s important to equip your kitchen with a cookware set that’s built from material that serves your culinary needs. Below are a the options you will find: Stainless steel is durable, versatile, and attractive. It’s not only easy to use and clean but also nonreactive. However, stainless steel absorbs and transmits heat poorly, so it’s often combined with a metal, like aluminum or copper, that has better thermal conductivity for quicker, more even heating. While aluminum and copper are reactive metals, when clad in stainless steel they do no...

When I first started tinkering with cars, one of the first big hurdles was how to

When I first started tinkering with cars, one of the first big hurdles was how to complete certain tasks without the ability to weld. Shaving trim holes, repairing rusty panels, or fabricating custom brackets all required the ability to melt and mate two different pieces of metal. And while there are a number of ways to tackle such tasks, arguably the easiest is MIG welding. Literally a “point and shoot” method, MIG or Metal Inert Gas welding is a process that uses electricity to melt and join together two pieces of metal. The learning curve for MIG welding is relatively gradual, making it the perfect process for the beginner to pick up and learn in his own backyard. What isn’t gradual, however, is the slippery slope that one finds themselves on once that basic technique is sorted out. Welding up those trim holes leads to repairing those rusty door corners. Pretty soon you’ll find yourself welding up suspension components, fabricating custom motor mounts, or crafting custom headers, all using the same MIG or GMAW (Gas Metal Arc Welding) technique. But what that slope will eventually lead to is the desire to take one’s welding to the next level; and that level is TIG. Gas Tungste...

CO 2 -breathing and piercing polymersomes as tunable and reversible nanocarriers

In the meantime, to ensure continued support, we are displaying the site without styles and JavaScript. Despite numerous studies on utilizing polymeric vesicles as nanocapsules, fabrication of tunable molecular pathways on transportable vesicle walls remains challenging. Traditional methods for building penetrated channels on vesicular membrane surface often involve regulating the solvent polarity or photo-cross-linking. Herein, we developed a neat, green approach of stimulation by using CO2 gas as “molecular drill” to pierce macroporous structures on the membrane of polymersomes. By simply introducing CO2/N2 gases into the aqueous solution of self-assemblies without accumulating any byproducts, we observed two processes of polymeric shape transformation: “gas breathing” and “gas piercing.” Moreover, the pathways in terms of dimension and time were found to be adjustable simply by controlling the CO2 stimulation level for different functional encapsulat...

ChargeTech 124,800 mAh Battery Pack: Charge Your iPhone 47 Times

One of the fundamental elements of a backpack when going on a journey is to take a battery pack in case your smartphone doesn’t make it through the day. These devices typically hold from 5000 to 20000 mAh and can charge a device a few times. For example, my 11300 mAh battery is rated at 42.7 Watt hours, and often the legal limit on aircraft is 100 Watt hours. Now imagine we scale that into something the size of a portable amplifier, that can charge laptops as well. These bigger battery devices has been around a while, varying in size and shape, but ChargeTech believes it has a nice sweet spot. Its new ‘portable power station’ features a 124,800 mAh capacity battery, which comes in at 462 Wh. This large battery pack, which won’t make it past the TSA, is designed for charging devices where there is no extra power, or for long journeys in the wilderness where power is a must.

Furthermore, it can playback music, and has an LED light to illuminate surroundings as well. The ChargeTech PS120K packs multiple batteries ...

Zombie Skittles suspiciously good at mimicking the taste of rotting flesh

Before Bertie Bott’s Every Flavor Beans made their debut on the page 22 years ago, there were certainly candies on the market that—in the Garbage Pail Kids tradition—looked comically gross. They resembled gummy boogers, but still functioned as candy should: providing a pleasant flavor sensation for too brief a moment. Now that we live in a post-Bertie Bott universe, The Jelly Belly Candy Company has found a way to not only market disgusting flavors, but to gamify them with the wildly popular BeanBoozled, a children’s Russian roulette where any given bean might be Tutti-Fruitti or Stinky Socks; Coconut or Spoiled Milk. Now, Skittles has jumped enthusiastically onto the pile with their latest release, Zombie Skittles. Just in time for Halloween, this gray-and-black package warns: “BEWARE. Most taste delicious but some taste like Rotten Zombie. Dare to try?” I’ve never felt more negged by a Walgreens purchase. I tore the bag open with undue force and proceeded one Skittle at a time. As if taunting me, the very first one out of the bag is a Zombie, masquerading as a Chilling Black Cherry. Having no basis of comparison yet, there’s a split-second where I believe I’ve simply forgotten...

Refining Approaches to Corrective and Preventive Rail Grinding

Railroads and transit systems are adopting innovative approaches to improve efficiency and productivity. As service providers look to better define grind quality. When it comes to correcting or maintaining the profile and surface condition of rail on North American railroads, there is one primary method: rail grinding. Rail milling, an established method in other parts of the world was recently introduced in a transit application in Canada, but at present, rail grinding is the method of choice. Freight railroads grind for two primary reasons: to maintain or manage rail shape (a fundamental aspect of wheel/rail interaction) and to minimize surface-initiated fatigue cracks that interfere with ultrasonic testing and can ultimately lead to rail defects. Transit systems grind for the same reasons, but also to control wheel/rail noise induced by rail corrugation. So, the goals of most grinding programs are to correct or maintain the desired rail profile; to remove surface damage, such rolling contact fatigue (RCF) and shells, spalls and corrugation (SSCs), which interfere with the ability of ultrasonic rail flaw detection systems to inspect the rail for internal defects. While there ...
