The portable machine, to be used for ‘riot control’ can cause dizziness, headaches, vomiting and even heart attack China has claimed to have developed the world’s first portable sonic device for crowd disperse, a research shows. Researchers at the Technical Institute of Physics and Chemistry at the Chinese Academy of Science said the device, which uses low frequency sonar, has passed their assessments including a trial test on the body. The project is a joint effort from the academy, the People’s Liberation Army medical centre, and police research lab. Sonic devices used in other countries can cause extreme discomfort such as dizziness, headaches , vomiting, organ damage and even heart attacks. However, researchers did not state the effects the newly developed weapon could pose on a human, according to their website . Professor Xie Xiujuan, who led the research, said the device was powered by a tube-shape vessel containing an inert gas. When heated, the gas particles vibrate and a deep, monotonous sound is emitted, according to South China Morning Post. The team has passed the budget proposal at a meeting on September 4, and approved it for mass producti...

When extra-virgin olive oil arrived in American kitchens around 1980, a set of myths came with it. You can’t use it for everyday cooking. You can’t use it for deep-frying. You must hoard your best stuff and bring it out only for occasional drizzling. Not one of those turns out to be true: Olive oil is an excellent all-purpose cooking oil, but at the time it was too expensive for cooks to use freely. In the meantime, the price has fallen, but global demand has grown far beyond supply, and the entire business has been transformed by technology, global trade and climate change. It has also been wracked by fraud, with millions of consumers around the world regularly paying for “extra-virgin” olive oil that is cut with inferior olive oil, mixed with cheaper oils, or colored with chlorophyll or beta carotene. Labeling has become a minefield, despite efforts by the European Union to enforce rules and make meaningful distinctions among terms like “made in Italy,” “imported from Italy” and “packed in Italy.” The European Union’s system of food certification (appearing as a DOP or PDO seal on a label) is relatively reliable...

Choosing the right boot for your job can be tricky, especially with so many makes and models out there. However, having the right footwear so that you feel comfortable and protected while at work can certainly make your workday easier. Although there are many parts that go into making the perfect work boot for each profession that requires one, ultimately choosing what fits your needs best is not complicated at all. This short guide will teach you how to do just that. Construction sites are wrought with hazards, which is why wearing protective gear is highly important. Work boots fitted with the appropriate toe protection material are important. The toe protection fittings should be ASTM (American Society for Testing and Materials)-rated. There are three types of protective toe caps: These are heavy, compact and make the most traditional form of protective toe caps. Steel material conducts temperature, so your feet will likely get cold during winter. Additionally, if you work on a construction site that has metal detectors or magnets, steel caps may not be an ideal choice. Over time, footwear manufacturers have improved steel toe caps and are now producing asymmetrical safety t...

Early adopters of LED lighting will remember 50,000 hour or even 100,000 hour lifetime ratings printed on the box. But during a recent trip to the hardware store the longest advertised lifetime I found was 25,000 hours. Others claimed only 7,500 or 15,000 hours. And yes, these are brand-name bulbs from Cree and GE. So, what happened to those 100,000 hour residential LED bulbs? Were the initial estimates just over-optimistic? Was it all marketing hype? Or, did we not know enough about LED aging to predict the true useful life of a bulb? I put these questions to the test. Join me after the break for some background on the light bulb cartel from the days of incandescent bulbs (not a joke, a cartel controlled the life of your bulbs), and for the destruction of some modern LED bulbs to see why the lifetimes are clocking in a lot lower than the original wave of LED replacements. Any discussion of light bulb lifetime would be incomplete without mention of the Phoebus cartel, an international organization formed in 1924 by the world’s leading light bulb manufacturers to manipulate the bulb market. As discussed by Markus Krajewski in “The Great Lightbulb Conspiracy”, the cartel assigned ...

Light bulbs have an enormous, everyday impact on the way our homes look and feel, and with a flood of new energy efficient LED bulbs filling the lighting aisle, you’ve got more options than ever. But how do you pick the right lights for the job? The trick is to think for a long time about how you typically put light to use in the different rooms in your home. That, more than anything, will dictate your lighting needs.  For instance, you might benefit from a super bright bulb in your favorite reading lamp, but prefer a gentler, more candlelike glow from the lamp at your bedside. To that end, here are some room-specific tips to help you zero in on the right lights — from energy-saving bulbs to CFL bulbs to LED smart bulbs to regular light bulbs — for your living space. Where appropriate, I’ve also included links to buy light bulbs from our tests — please note that CNET may get a share of revenue from those purchases. If you have rooms with high ceilings — an entryway, for instance, or maybe a staircase with overhead lights up above — you’ll want to prioritize brightness over softness in your light bulbs. After all, the higher up your...
