20 Things You Need to Let Go of to Find Lasting Peace of Mind
There are some things in life not worth keeping. Letting go of negative qualities which dominate your ego will only lead to a greater sense of self and happiness. We hold on to so many things that cause us a great deal of pain, stress and suffering when we could otherwise let them go. We attach ourselves to their energy on a daily basis. Isn’t it time to reprogram ourselves and our lives? Isn’t it time to change our truth? Here are 20 things you need to let go of in order to find lasting peace of mind. 1. Your Need to Always Be RightThere are so many of us who can’t stand the idea of being wrong — wanting to always be right — even at the risk of ending great relationships or causing a great deal of stress and pain, for us and for others. We love to right-fight. It’s just not worth it. Whenever you feel the ‘urgent’ need to jump into a fight over who is right and who is wrong, ask yourself this question, from Wayne Dyer: “Would I rather be right, or would I rather be kind?” What difference will that make? Is your ego really that big? Ultimately everybody has their own perspective. Yours is only one and it may be no more correct than another. |
Educating the immune system to prevent allergies
Thu, 05/14/2015 Julie Robert, McGill University A research team at the Montreal Children’s Hospital from the Research Institute of the McGill University. Health Centre (RI-MUHC) is bringing them hope with a potential vaccine that nudges the immune response away from developing allergies. The findings published in Mucosal Immunology have major clinical implications since allergies and asthma are lifelong conditions that often start in childhood and for which there is presently no cure. "Our study, for the first time, offers a potential way of preventing allergies by using a molecule that redirects the immune response away from the allergic response," says lead author Dr. Christine McCusker, allergist at the Montreal Children’s Hospital and researcher at the RI-MUHC and associate professor in the Dept. of Pediatrics at McGill University. "This discovery is very promising since the molecule we developed can be administered by a drop into the nose as a spray." The reasons why allergies develop remain unexplained, but it is believed that all children are born with the potential to develop allergies. Children without allergies make a shift to the non-allergenic immune response when allergens are around. Those who do develop allergies have not shifted by the time they are exposed to the allergen. Dr. McCusker and her team from the Meakins-Christie Laboratories started to work on a specific molecule—called STAT6—which is important in the development of allergic response. They thought that if they could inhibit this molecule they would reduce the symptoms of allergic airways disease, such as asthma, in allergic animals. They also hoped to prevent the allergy from developing entirely. To do this, they developed an inhibitor peptide called STAT6-IP that was given to newborn mice by intranasal droplet. "By giving the peptide STAT6-IP very early on, before allergies are present, we were able to teach the immune system. So when we tried to make the mice allergic later on, we couldn’t because the immune system had ‘learned’ to tolerate allergens," explains Dr. McCusker. "What’s beautiful about our approach is that you do not have to couple it with a specific allergen, you only use this peptide. It just redirects the immune system away from the allergic response and then it will not matter if the child is exposed to pollen, cats or dogs, because the immune system will not form an aggressive allergic reaction anymore," adds Dr. McCusker. "In subjects who have the propensity to develop allergies, their system has made the ‘wrong’ decision somewhere along the line," she says. "It is like educating the immune system to follow the path we want it to follow." Researchers are now studying the effect of this peptide to see in what other areas this type of immune education will prevent disease, such as with food allergies. They then hope to move this discovery to clinical trials in humans. Source: McGill University.

India to Launch First Homegrown Carrier
May 14, 2015 India is set to launch its first indigenous aircraft carrier later this month, according to local media reports. On Thursday The Hindu reported that India’s first indigenous aircraft carrier, INS Vikrant, will be launched from Cochin Shipyard on May 28. “All major equipment has gone into the vessel, which has now acquired the shape of an aircraft carrier, with a finished hull. Barring a bit of ongoing work on the superstructure, structural work is all over and the internal compartments have all been welded in,” an official at shipyard was quoted as saying. The INS Vikrant will displace 40,000 tons and feature a short-take off but arrested recovery (STOBAR) system, rather than the catapult-assisted take-off but arrested recovery (CATOBAR) launch system used by current U.S. aircraft carriers. The ski-slope launch system will limit the INS Vikrant’s ability to launch heavy aircraft from its deck. However, the carrier will reportedly hold some 36 combat jets, which can launch at intervals between 2-3 minutes. The ship is expected to carry the Russian-made Mikoyan MiG 29 K fighter. India had previously launched the still uncompleted carrier back in 2013, after phase I of its construction was finished. The upcoming launch marks the completion of its structure. The carrier is set to undergo testing starting in 2017, and—if everything goes to plan—will be inducted into India’s navy sometime in 2018. India currently operates two aircraft carriers, both of which are foreign built. The first is the the INS Viraat, an ageing, 55-year-old former British carrier, which is set to be decommissioned next year. Besides the INS Viraat, India’s Navy also operates the the INS Vikramaditya, a refurbished carrier it purchased from Russia for $2.35 billion. The 44,400-ton INS Vikramaditya was commissioned in Russia in 2013, and formally inducted into the Indian Navy back in June of last year. Also this week, a senior Indian defense council has approved a budget for the country to build its second indigenous aircraft carrier. According to local media reports, the Defense Acquisition Council (DAC), which is chaired by India’s defense minister, Manohar Parrikar, approved a slew of deals this week, including allocating 30 crore (roughly $5 million) to build India’s second indigenous aircraft carrier. The reports said the funds will go to “commencement of preparatory work for construction of Indian Aircraft Carrier 2.” Earlier this year, India had said it will fast track production of the 65,000-ton carrier, dubbed the INS Vishal, under its indigenous aircraft carrier-II (IAC-II) project. The project is being accelerated partly to deal with China’s rapidly growing carrier fleet, as well as because of the INS Viraat’s looming decommissioning. The INS Vishal may be nuclear powered and boast the more advanced catapult-assisted take-off but arrested recovery (CATOBAR) launch systems. The United States has recently expressed an interest in sharing carrier technology with India. Zachary Keck is managing editor of The National Interest. You can find him on Twitter: @ZacharyKeck.

3-D microbattery suitable for large-scale on-chip integration
Tue, 05/12/2015 - 8:18am Rick Kubetz, University. of Illinois, Urbana-Champaign
Image of the holographically patterned microbattery.By combining 3-D holographic lithography and 2-D photolithography, researchers from the Univ. of Illinois at Urbana-Champaign have demonstrated a high-performance 3-D microbattery suitable for large-scale on-chip integration with microelectronic devices. "This 3-D microbattery has exceptional performance and scalability, and we think it will be of importance for many applications," explained Paul Braun, a professor of materials science and engineering at Illinois. "Micro-scale devices typically utilize power supplied off-chip because of difficulties in miniaturizing energy storage technologies. A miniaturized high-energy and high-power on-chip battery would be highly desirable for applications including autonomous microscale actuators, distributed wireless sensors and transmitters, monitors and portable and implantable medical devices." "Due to the complexity of 3-D electrodes, it is generally difficult to realize such batteries, let alone the possibility of on-chip integration and scaling. In this project, we developed an effective method to make high-performance 3-D lithium-ion microbatteries using processes that are highly compatible with the fabrication of microelectronics," stated Hailong Ning, a graduate student in the Dept. of Materials Science and Engineering and first author of the article appearing in Proceedings of the National Academy of Sciences. "We utilized 3-D holographic lithography to define the interior structure of electrodes and 2-D photolithography to create the desired electrode shape." Ning added. "This work merges important concepts in fabrication, characterization and modeling, showing that the energy and power of the microbattery are strongly related to the structural parameters of the electrodes such as size, shape, surface area, porosity and tortuosity. A significant strength of this new method is that these parameters can be easily controlled during lithography steps, which offers unique flexibility for designing next-generation on-chip energy storage devices." Enabled by a 3-D holographic patterning technique—where multiple optical beams interfere inside the photoresist creating a desirable 3-D structure—the battery possesses well-defined, periodically structured porous electrodes, that facilitates the fast transports of electrons and ions inside the battery, offering supercapacitor-like power. "Although accurate control on the interfering optical beams is required to construct 3-D holographic lithography, recent advances have significantly simplified the required optics, enabling creation of structures via a single incident beam and standard photoresist processing. This makes it highly scalable and compatible with microfabrication," stated John Rogers, a professor of materials science and engineering, who has worked with Braun and his team to develop the technology. "Micro-engineered battery architectures, combined with high energy material such as tin, offer exciting new battery features including high energy capacity and good cycle lives, which provide the ability to power practical devices," stated William King, a professor of mechanical science and engineering, who is a co-author of this work.

These 14 Photos Capture How Polluted China Has Become, And It’s Terrifying…
Apr 4, 2015
Amanda Froelich, True Activist
From the trash-strewn Great Wall of China to oil-filled lakes, this land and its people are suffering from the effects of unsustainable industrialized living.
In case you haven’t heard, China has declared war on pollution, as rates of environmental toxicity are beyond tolerable and are negatively affecting its population. As reported by NationalInterest, the first thing you notice when arriving in China is a cloud of smog that hugs its industrialized cities.
And that toxicity is the #1 source of social unrest for Chinese citizens. In fact, it’s so bad, individuals are forced to wear masks on their daily commute to work as pollution in cities like Beijing is 40 times higher than International Safety Standard.
But if statistics don’t speak loudly enough, the following photos certainly do. China may be the world’s leading supplier of goods, but the repercussions from its unsustainable industrial habits (which fuel the lives of many who are reading this piece) are having a devastating toll on the environment and health of its people.
Scroll through and see just how toxic some of China’s landscapes and cities have become.

Review: Basis Peak fitness and sleep tracker
Gizmag reviews the Basis Peak fitness tracker (Photo: Simon Crisp/Gizmag.com) The Basis Peak is a wrist-worn fitness tracker which is jam-packed with sensors to monitor an array of information about your body and activity. It also automatically detects whether you're walking, running, cycling or sleeping, and can deliver smartphone notifications to your wrist. Gizmag recently spent a bit of time with the fitness tracker to see how well it performs, and how useful all of that information really is. The Basis Peak fitness tracker is aimed squarely at people who want access to as much general activity information as a wrist-worn tracker can deliver, and who wouldn't mind getting a taste of smartwatch functionality at the same time. It tracks heart rate, steps, calories burned, sweat levels, skin temperature and sleep quality, while an update which landed earlier this year also means its big high contrast screen can be used to display smart notifications including SMS, e-mail, incoming calls, and events. All of this means the Basis Peak is, at least on paper, one of the most capable all-round fitness trackers on the market, and a considerable upgrade to the original Basis B1. As such, potential buyers are probably also going to be eyeing up the likes of the Fitbit Surge, Garmin Vivoactive, the Fitbit Charge HR and the Microsoft Band, along with more dedicated sports devices like the TomTom Runner Cardio and Garmin fēnix 3. In the box you'll find the waterproof Basis Peak along with a magnetic USB charging cradle. While promotional blurb states you should get four days of battery life out of a full charge, we found it was more like three days, and we actually preferred to charge it more frequently during periods of inactivity like sitting at a computer. The packaging clearly spells out what the Basis Peak is capable of, though you'll need to refer to the website to find out whether your Bluetooth Smart smartphone is compatible. While we've seen some people struggle to get up and running with the Basis Peak, our experience of installing and pairing was relatively straight forward. That said, it was lightly frustrating that firmware updates cannot be done through the USB charging cradle and need to be carried out via a paired smart-device running the Basis Peak app. For us this was primarily a Motorola G (2nd Gen), but we also tested the iOS version of the app on an iPad. It was only after starting to use the Basis Peak that we made a key observation: it looks a lot better than expected. Marketing shots do the tracker a disservice, and it's far from the Quasimodo of the fitness tracker world that you might be expecting. In real life it looks like a smart digital watch which will fit in whether you are wearing jeans and a t-shirt or a suit. Its only crime is that it isn't photogenic. The body is available in matte black (which we tried) or brushed metal, and interchangeable straps mean you can mix it up a bit. A large high contrast always-on touchscreen display on the Basis Peak makes it a very viable watch replacement, and means that information is considerably easier to see than on many other fitness trackers. Even in bright conditions and while running it's possible to see and read the screen which is made with Gorilla Glass 3. In the dark, an upwards swipe on the right of the display activates a backlight. Navigating menus and settings is simple using the touchscreen (there are no buttons) though it's not as responsive or consistent as the Garmin Vivosmart. Once you're wearing the Basis Peak, there's very little you need to do. Unlike most other fitness trackers, you don't need to tell it when you're going for a walk, run, or bike-ride, or when you're going to bed. Instead everything is logged automatically and your main interactions with the device are probably going to be to check the time or your notifications, and to keep an eye on your heart rate or daily activity totals. Whether this is a good thing or not is something we'll come to shortly. While a 3-axis accelerometer allows the Basis Peak to track your steps in the same way as most other trackers, that's only the tip of the iceberg. Sensors allow it to also constantly monitor heart rate, sweat levels, skin temperature and sleep quality, with a breakdown of periods of light, deep, and REM kip. All of this means the device has great potential, if the information is used correctly. The only things missing are GPS, and the fact that the Peak only logs steps and not distance, which is sure to irk some users. That said, the Peak can use Bluetooth to stream its info to apps which have GPS, to see distance and pace, along with other fitness data. In our experience automatic tracking was equally one of the most impressive and infuriating features of the Basis Peak. For someone as memory-challenged as myself it was liberating to know that I could head out on a run or bike ride without having to remember to manually start activity tracking. I've lost count of the number of half-tracked runs I've racked up recently with other devices. Automatic detection of walking, running and cycling was flawless with the Peak recognizing within seconds what I was doing when. That said, because all this Body IQ tagging of exercise is automatic, there's no way to do it manually. This is important because the Basis Peak only recognizes walking, running and cycling, if you are doing something else like weights or rowing, it will not show up in your activity feed. Yes, data from all those sensors is still being recorded and is accessible in the web and smartphone apps, or to export, but it doesn't make it easy to use. Similarly there's no way to manually log exercise completed when not wearing the Peak. Sleep tracking is another example of great function marred by the Peak's insistence of doing everything automatically. Giving much more information than most rival sleep trackers, it will identify periods of light, deep, and REM sleep, along with logging when you toss or turn in bed. However, a worrying number of periods of sleep were recorded whenever I sat down at a computer or to watch TV. Either I unknowingly suffer from narcolepsy, or the Peak struggles to distinguish between inactivity and sleep. What make this worse is the inability to correct false positives anywhere in the app or on the website, meaning overall sleep data is skewed. In terms of the tracked numbers, the Basis Peak was fairly consistent with other devices, for example a 30 minute run logged as 5,220 steps on the Peak compared to 5,006 on the Fitbit Charge HR and 5216 using the Tickr X. Average heart rates came in at 161, 162 and 162 bpm respectively with top heart rates or 181, 175 and 180 bpm. A comparison of heart rate charts showed very similar patterns across all results. The selection of information which can be displayed on the screen of the Basis Peak is more limited than some rival devices. On their wrist, users are limited to watch functionality (which annoyingly lacks an alarm or stopwatch/timer) checking their current heart rate, recent activity and daily totals. While all of this is incredibly easy to see and navigate, it's a shame the information isn't more usable. For example using the vibration function to notify users as they moved between heart rate zones, like on the TomTom Runner, would make the tracking more handy at the time of exercise. However, once you load up either the smartphone app or Basis website you suddenly have access to a selection of tracked data which few other fitness trackers can compete with. This is presented in a selection of charts, graphs and colorful patterns which all make the information very easy to access and identify patterns from. On the MyBasis website, information is broken down into My Habits, which shows progress towards reward badges, Insights, where you can check out daily breakdowns of key activity and sleep events, and Data, where you can explore all of the information collected by the Basis Peak. Within the smartphone app, this consists of a Dashboard overview, more detail on Habits, an Activity Feed, and a Chart View. While this, along with the ability to export tracked information, should be enough to keep even the most data-hungry exerciser happy, there's still the question of how usable and actionable this data is for the majority of people. On a more practical level, the Basis approach to jockeying you along is one of the most compelling we've experienced on a fitness tracker, and ideal if you don't want to dive head-first into your exercise data. You start off with a couple of basic Habits, targets for things like wearing the Basis Peak or walking a set number of steps each day. The more you complete these targets for the set number of times each week, the more points you get to add more habits – which can include things like increasing walking in a morning, getting a consistent bedtime, or running or cycling for so many minutes per day. We found this system more encouraging and engaging than those on rival devices, but it's a shame that you can only compete against yourself and there are no native social aspects to the Basis Peak. A recent update to the Basis Peak gave the device a basic selection of smartwatch-lite features, such as the ability to display information about incoming emails or SMS messages on the wrist, as well as incoming calls which can be declined without touching the phone. While this is nice to have, the implementation is not as smooth as with other fitness trackers with smartwatch aspirations. For example, while messages flashed up on the Garmin Vivosmart as the exact time as on paired phone, with the Peak there is a delay of around five seconds. This was just long enough to doubt notifications were coming through, and then reach for a phone just as it flashed up on the Peak's screen. The Basis Peak is a solid fitness tracker which gives you access to all the information you could wish for (with the exception of GPS). It's a smart-looking device which is packed with sensors and is ideal for people who want access to masses of data, and who aren't afraid to get their fingers dirty using that information. However, it's less geared to those who just want a quick overview of their activity, and it's arguably not quite as impressive as it should or could be. Seemingly basic features like a stopwatch and alarm are missing, as is a distance measurement. Equally, the insistence of doing everything automatically means users can feel like they are not in control. It feels like a series of firmware updates could easily transform the Basis Peak into one of the most impressive fitness trackers on the market, and given it has already gained notification abilities since it launched, that is a possibility. But for now buyers are getting a good fitness tracker, not the great one it could be. The Basis Peak is available for US$200 and come in black or silver options. Product page: Basis Peak

Health benefits of used coffee grounds
Wed, 05/13/2015 - 8:57am American Chemical Society Coffee has gone from dietary foe to friend in recent years, partly due to the revelation that it’s rich in antioxidants. Now even spent coffee-grounds are gaining attention for being chock-full of these compounds, which have potential health benefits. In the Journal of Agricultural and Food Chemistry, researchers explain how to extract antioxidants from the grounds. They then determined just how concentrated the antioxidants are. María-Paz de Peña and colleagues note that coffee—one of the most popular drinks in the world—is a rich source of a group of antioxidants called dietary phenolic compounds. Spent grounds, however, often end up in the trash. But recently, scientists have discovered that antioxidants aren’t just in the brewed coffee; they’re also in the used grounds. De Peña wanted to figure out the total phenolic content in extracts from these leftovers. The researchers used three different methods to release antioxidants from spent grounds and found high levels of phenols in the extracts—sometimes at higher levels than in brewed coffee. Thus, they have the potential to serve as additives to enhance the potential health effects of other food products, the scientists conclude. Source: American Chemical Society
