Soluções tecnológicas que parecem brilhantes em si mesmas (milho transgênico, maquina que composta resíduos orgânicos em 24h; medicamentos que destroem tumores; químicos que acabam com ervas daninhas; revestimento que evita aderência em frigideiras; fibras para telhas com ótimas propriedades térmicas; etc.) mostram-se um verdadeiro pesadelo quando colocadas em contexto, e sempre produzem mais dano do que lucro. Education and policy: Re-educating Rita. New computers could delete thoughts without your knowledge, experts warn. “Thou canst not touch the freedom of my mind,” wrote the playwright John Milton in 1634.
But, nearly 400 years later, technological advances in machines that can read our thoughts mean the privacy of our brain is under threat. Now two biomedical ethicists are calling for the creation of new human rights laws to ensure people are protected, including “the right to cognitive liberty” and “the right to mental integrity”. Scientists have already developed devices capable of telling whether people are politically right-wing or left-wing.

Journey from our solar system to Earth and explore the manmade objects along the way. (European Space Agency) You Know Microwaves Are Bad For You But This Is What You Didn't Know. The Southwest Museum of Engineering, Communication, and Computation (SMECC) reported that over 95 percent of American homes possess a microwave oven, and it is regarded to be a necessary item in every household.
These ovens were originally sold as “Radaranges,” and they work as a result of electromagnetic waves which pass through food, causing the molecules to move and thus heat up. These waves are electromagnetic energy and travel at the speed of light. Empresa cria máquina que decompõe resíduos orgânicos em 24 horas. Eco-Wiz. Overview ecoDigester is an entirely self-contained and continual feed disposal system for organic waste.
It is designed to convert solid food waste materials into either liquid nutrient or reusable water which can be applied for multiple purposes e.g. washing floor or watering of plants. ecoDigester increases the speed of the natural decomposition process through biological means like maintaining optimal levels of aeration, moisture, temperature. Under these controlled conditions, microorganisms can safely decompose food waste at a rate much faster than under natural conditions which are subjected to soil and groundwater conditions. ecoDigester can safely and quickly decomposes any kind of food waste including vegetables, fruits, scraps, raw and cooked meat, fish, poultries and dairy products.

Suas lâmpadas estão te cegando - e te deixando com depressão. Security Check Required. RoboDragonfly: Tiny Backpack Turns Insect into a Cyborg. Scientists look to flying animals — birds, bats and insects — for inspiration when they design airborne drones.
But researchers are also investigating how to use technology to interact with, and even guide, animals as they fly, enhancing the unique adaptations that allow them to take to the air. To that end, engineers have fitted dragonflies with tiny, backpack-mounted controllers that issue commands directly to the neurons controlling the insects' flight. This project, known as DragonflEye, uses optogenetics, a technique that employs light to transmit signals to neurons. And researchers have genetically modified dragonfly neurons to make them more light-sensitive, and thereby easier to control through measured light pulses. [7 Animals That Wore Backpacks for Science]
8 Ways Technology Makes You Stupid. People assume that iPhones, laptops and Netflix are evidence of progress.
In some ways, that's true. A moderate amount of Googling, for instance, can be good for your brain, and there are apps that can boost brain function and activity. Yet tech advancements also come with some unintended consequences. Wi-fi: uma perigosa e invisível ameaça à saúde - saiba como se proteger! O sinal wi-fi está em todas as redes sem fio que fornecem conexão à internet para vários aparelhos sem a necessidade desses cabos chatos.
Wi-fi está ao nosso redor, mesmo em lugares onde não é necessário. Produtos do plástico estão adoecendo as pessoas e falindo o governo – Jornal Ciência. Consumer Physics. There may finally be a food scanner that actually works. Last year, a device called Tellspec raised more than $386,000 on Indiegogo, claiming to be able to identify the “allergens, chemicals, nutrients, calories, and ingredients in your food” using a single hand-held scanner costing $250.
A few months later, an Indiegogo campaign for GoBe, a “wearable calorie-counting device” was even more successful. Tellspec: amazing IR spectrometry advance or scam? - International Skeptics Forum. A few other things.
First, Raman spectra spread out information over a fairly small band of wavelengths---say 50nm. That means you need, not just any cheap spectrometer, but a very-high-dispersion spectrometer, to meaningfully separate these wavelengths. Now, the fiber-resonator "spectrometer on a chip" that Cosmicaug links to---neato! ---is indeed high-resolution. But that's not what Tellspec says they're doing.
If you're not working at high resolution, then you're going to be looking at overlapping spectra from everything in the system. Have You Contributed to a Health Scam? - Olga Khazan. If it works, the GoBe will be life-changing. But it’s a big if. The GoBe is a bracelet that looks like a small microplane has been affixed to a black watchband—the top of the microplane is a display, and its underside is a sensor. Through its “patented flow technology,” the GoBe promises to measure the wearer’s heart rate, calories burned, sleep, and stress levels.
That’s all conceivable, given what the FitBit and other body trackers already measure. We Took The Laser Scanner That Tells You What's In Your Food Out For A Spin. To make our cities safer and more attractive to cyclists, we need some bold politics. The roads need to be made hostile to cars, and as you can imagine, that doesn’t go over with drivers, even though having more cyclists improves the city for everyone, including car users. Taking London’s new Quietways scheme as an example, London's Cycling Commissioner Andrew Gilligan explained to a London cycling conference last week how weak local politicians make infrastructure improvements for pedestrians and cyclists almost impossible. Myth or Miracle: Is TellSpec's Nutritional Scanner Too Good to Be True? Imagine a handheld device that can scan your food to deliver accurate, real-time data about its chemical and nutritional content—including calories and potential allergens. That's the vision cooked up by TellSpec, a Canadian startup that claims to be developing the world’s first “food scanner.”
Using Raman spectroscopy, the TellSpec fires a laser into a given food item, measures the reflected light, and then sends the data to TellSpec’s cloud servers. There, the information is measured against reference data and run through a series of algorithms. In the final step, the results are sent back to the user and displayed via a mobile app. The whole process takes about three seconds. Stupid Legal Threats: Sketchy Crowdfunded Food Scanner Company Threatens To Sue Site That Reported On Phantomware Product. Pando. Dott. Montanari: "la torcia al plasma e' una tecnologia fallita" Perigos de pneus reciclados! This video explains how those plastic bits in face washes, scrubs, and toothpastes can hurt ecosystems. By now, most of us know that if we want our consciences to be as squeaky clean as our faces, we have to ditch our most beloved scrubbing products. While microbeads — the tiny plastic bits most commonly found in face washes, scrubs, and toothpastes — might do great things for your pores, they could also quietly wreak havoc on the environment by steadily streaming into the Great Lakes and oceans.
Couldn’t care less about fish? Get this: Through the magic of the food chain, these little plastic beads actually carry the potential to come back around and screw with human health. We turned to Andrew Maynard, mastermind behind the Risk Bites YouTube channel and director of Arizona State University’s Risk Innovation Lab, to figure out just how hazardous an exfoliator could be. Check out his findings in the video above! How technology has stopped evolution and is destroying the world.
It has become something of a mantra within the sustainability movement that innovations in technology can save the world. But rather than liberating us, Doug Tompkins, the cofounder of retail brands The North Face and Esprit, believes technology has enslaved us and is destroying the very health of the planet on which all species depend. Tompkins, 70 has used his enormous wealth from selling both companies to preserve more land than any other individual in history, spending more than £200m buying over two million acres of wilderness in Argentina and Chile.
He challenges the view that technology is extending democracy, arguing that it is concentrating even more power in the hands of a tiny elite. What troubles him the most is that the very social and environmental movements that should be challenging the destructive nature of mega-technologies, have instead fallen under their spell. Hormone-Mimicking, Endocrine-Disrupting Nightmare? L.A. Just Dumped Millions of Plastic Balls into Its Drinking Water. Why are Shade Balls Black Instead of White? Why shade balls aren’t such a great idea after all. Here’s how the news works circa 2015: A story gets reported, usually by journalists for major media outlets like the Associated Press or The New York Times. Then, when it starts to get traction on social media and shows up in your Twitter feed or your Facebook, the aggregators jump on it. Aggregators are human vultures with lots of student loan debt who put their own particular spin on someone else’s story by turning it into a listicle or writing a clever reaction piece or reducing a 3,000-word feature into a meme.
