Comments Off on MIT researchers invent an ingestible battery powered by stomach acid

MIT researchers have developed a new safe-to-swallow battery powered by stomach acid. The technology could significantly aid in the powering of ingestible electronic devices currently being used for drug delivery and internal medical procedures like colonoscopies – as well as other wearable technology . MIT drug delivery device As New Atlas reports, “safe-to-swallow batteries” are currently being developed to power these ingestible electronic devices, but up until recently they have posed problems. This recent development out of MIT is expected to provide a cheaper and safer alternative to those batteries currently on the market. The battery was the result of a study by a team of MIT researchers led by senior authors, Giovanni Traverso and Robert Langer who have developed a number of internal devices, for which they wanted a safe, reliable power source. “We need to come up with ways to power these ingestible systems for a long time,” Traverso told New Atlas . “We see the GI tract as providing a really unique opportunity to house new systems for drug delivery and sensing, and fundamental to these systems is how they are powered.” They started with the fact that the majority of batteries are powered by acid, and realized they could take advantage of acid in the stomach. Their concept is based on the simple battery concept that involves putting a piece of zinc and copper into a lemon, where the citric acid becomes an electrolyte that can carry a current between the two metals – creating enough power to run an LED . Related: MIT designs innovative wearable tech that makes it easier to network As New Atlas explains, “The researchers scaled that principle down by attaching their own zinc and copper electrodes to the outside of a small, ingestible device containing a temperature sensor and a 900 MHz transmitter. Like in the lemon, the stomach acid can carry the electric current from the zinc to the copper and power the device, which, when tested in pigs, was able to take temperature readings and then send that data wirelessly, every 12 seconds, to a receiver up to 2 m (6.6 ft) away.” According to senior author Anantha Chandrakasan, this design solves problems with internal medical devices, such as energy generation , conversion, storage and utilization, opening up new horizons for the technology. “This work allows us to envision new medical devices where the body itself contributes to energy generation enabling a fully self-sustaining system.” Via New Atlas Images via MIT

Comments Off on Off-grid eco-retreats reconnect you to serene nature in Brazil

Couples looking for a romantic escape can unplug in comfort at these off-grid eco-cabins hidden away in the remote coastal mountains of Brazil. Surrounded by nature and captivating views, these solar-powered getaways are the latest installments of Minimod , a prefabricated modern home designed by MAPA Architects. Cozy and dreamy, these Minimod Catuçaba dwellings are the first of their kind in Brazil and are even available to rent on AirBnB. Located on the five-hectare estate of a former coffee plantation that dates back to 1840, the two Minimod Catuçaba cabins border the Serra do Mar State Park and overlook a verdant landscape of trees and mountains. The two 45-square-meter units are placed 1,000 meters apart and were built with different viewpoints and different layouts—one is cross-shaped while the other is rectangular. Both cabins were prefabricated offsite in a factory using cross-laminated timber and are equipped with solar panels and full-height glazing. “We invited Minimod to join the Fazenda Catuçaba community because we believe it is a revolutionary concept in Brazil, that shares in our vision of natural living,” write Casas de Catuçaba , the operators of the eco-cabins. “The Minimod is a primitive refuge with a modern twist. It´s not just a living space, it is an experience. It is a technological experience applied to the natural landscape, an invitation to live on the border between of the natural and the man-made. The Minimod incorporates a silencing system to enhance the experience between the inhabitant and the landscape.” Related: MAPA Architects’ Tiny MINIMOD House is a LED-Lit Prefab Home for Off-Grid Living Each cabin accommodates four and includes two beds, bathroom, kitchen, and living area with an indoor fireplace. Guests have access to trails through the woods that lead to a lake and floating deck, as well as an outdoor fire pit. The cabins are available to rent on AirBnB for $267 per night. + Minimod Catuçaba Via ArchDaily Images via Minimod Catuçaba and © Leonardo Finotti

Tesla extends free charging at Supercharger stations

Comments Off on Tesla extends free charging at Supercharger stations

As of two weeks from now, there will be no more free lunch for Tesla car buyers, as the company will be cutting off free access to its Supercharger network of charging stations as of January 15, 2017. Engadget reports that this is actually somewhat of a reprieve for Tesla customers, as the cutoff was initially supposed to be January 1, 2017. According to Engadget , Tesla announced this change was coming a few months ago, telling customers they were soon going to have to pay for their own electricity. Given the recent announcement, potential buyers have just a short period in which to get unlimited free electricity for their Tesla car, which amounts to a huge bonus for anyone buying before January 15. Cars bought after that date will be limited to just 400 kilowatt hours of free power per year, and owners will have to pay for the rest. According to Tesla, that’s roughly enough power to drive for about 1,000 miles. Related: Tesla’s next Supercharger could charge electric cars in mere seconds Tesla says charging beyond that amount will be available at an additional fee, the amount of which has yet to be announced. They have said it “won’t be too expensive” and will cost drivers “less than the price of filling up a comparable gas car.” So if you’re thinking about a Tesla, now could be the time to buy. This announcement comes shortly after CEO Elon Musk hinted that a new generation of Superchargers could charge a Model S in just seconds. Near the end of December 2016, Musk hinted in a tweet that the Supercharger V3 would have an ouput of at least 350 kilowatts, or more than double the output of the current Superchargers in Tesla’s network.

Medical hackers create $30 DIY EpiPen in defiance of corporate greed

Comments Off on Medical hackers create $30 DIY EpiPen in defiance of corporate greed

This summer, news of price hikes affecting the EpiPen went viral. Since 2007, the cost of the drug has risen sharply from $57 a dose to $318 – an increase of 461 percent. This kind of price hike would be outrageous for any medication , but it’s particularly galling in the case of the EpiPen. The epinephrine autoinjectors are a lifesaving drug of last resort meant to halt anaphylactic allergic reactions long enough for people with severe allergies to seek emergency care. Now, a group of medical hackers has figured out how to create a DIY replacement from common drugstore parts for just $30. https://youtu.be/ldFFJRdhVs8 The “EpiPencil” created by the Four Thieves Vinegar collective consists of an auto injector device designed to help diabetics , paired with a hypodermic needle capable of piercing through the skin into the muscle – the location where the medication needs to be injected in order to be effective. The active ingredient, epinephrine, can be obtained from a pharmacy with a prescription from a doctor. For those who are unable to afford an EpiPen for their allergies, this DIY hack could literally prove lifesaving. However, it is worth mentioning that many experts have voiced concern about the EpiPencil and warned that it’s not advisable to try to create a piece of medical equipment at home – it can be difficult to ensure the correct dose is being administered, the epinephrine inside is delicate and might lose its effectiveness if stored this way, and of course, if someone were to create the device without paying close attention to hygiene , it could become contaminated. A miscalibration of the device could even cause the medicine to be injected into a vein, which can have dangerous side effects. Related: 6 designs that could save your life Drawbacks aside, the video from Four Thieves Vinegar proves that Mylan’s price hikes have nothing to do with the cost of actually producing the EpiPen. If nothing else, the DIY autoinjector highlights the out of control corporate greed which allows such unreasonable price hikes in the first place. + Four Thieves Vinegar Via Minds

40% of the top sunscreens don’t meet official guidelines for sun protection

Comments Off on 40% of the top sunscreens don’t meet official guidelines for sun protection

When summer arrives, people turn to sunscreen to protect themselves from the sun . But a new study casts major concern over whether the most popular sunscreen brands actually protect users . A team of researchers led by a dermatologist scrutinized highly rated sunscreens on Amazon, and uncovered a shocking statistic: 40 percent of those sunscreens don’t comply with American Academy of Dermatology (AAD) guidelines for sun protection. Dermatologist Shuai Xu worked with colleagues at Northwestern University and the Duke University School of Medicine to publish an original investigation into sunscreen in the journal JAMA Dermatology in early July. Xu’s team found 6,500 sunscreens on Amazon. Based on how many customers reviewed a product and how highly they rated the product, Xu’s team selected the top 1 percent – 65 sunscreens – to study. 26 of the products ” did not adhere to AAD guidelines .” Related: EWG’s 2016 best and worst sunscreen lists are out – is your favorite listed? AAD guidelines say a sunscreen should have a SPF of at least 30 (and it should be noted anything past SPF 50 likely doesn’t offer more protection ), be resistant to water, and protect against UVA and UVB rays (labeled as “broad spectrum”). Some of the sunscreens that failed to meet guidelines are Blue Lizard Australian Sunscreen, Sensitive SPF 30+; Neutrogena Oil Free Moisture SPF 35; and Eucerin Daily Protection Moisturizing Face Lotion, according to Xu’s study . All three of those sunscreens had the required SPF and were labeled broad spectrum but were not water resistant. The researchers found water resistant sunscreens were generally more expensive. They also discovered sunscreen prices aren’t necessarily related to SPF. Xu said , “As doctors, we want to have some input and insight into what consumers are using, because sunscreen is a really important part of skin health . We think of sunscreen as a form of topical medicine . It’s not a luxury product.” Via The Washington Post Images via Wikimedia Commons and Skeyndor Cosmética Científica on Flickr

‘Nightmare’ bacteria found in the U.S. resists all known antibiotics

Comments Off on ‘Nightmare’ bacteria found in the U.S. resists all known antibiotics

Last November researchers in China discovered a strain of bacteria that resisted all forms of antibiotics – including the ” last-resort drug ” colistin. Now, government officials have found the first case of an antibiotic-resistant superbug in the United States. A 49-year-old woman in Pennsylvania went to the doctor for symptoms akin to a urinary tract infection, however the ailment did not respond to antibiotics . She had not traveled during the five months before her infection. Doctors at Walter Reed National Military Medical Center obtained samples and tested them, finding they did not respond to colistin. They released a study detailing the drug-resistant bacteria. Related: Antibiotic resistant bugs could kill 10 million people each year by 2050 The bacteria doesn’t respond to drugs because of a particular gene called mcr-1. According to the U.S. Department of Health and Human Services (HHS), mcr-1 “exists on a plasmid,” or a bit of DNA, and plasmids can travel between bacterium. The bacteria found in the woman had actually been infected with mcr-1 via a plasmid. Director of the Centers for Disease Control and Prevention Thomas Frieden said , “The more we look at drug resistance, the more concerned we are. The medicine cabinet is empty for some patients. It is the end of the road for antibiotics unless we act urgently. We risk being in a post-antibiotic world.” According to Reuters , both feeding antibiotics to livestock and over-prescription have contributed to the dilemma we face. Between 30 to 50 percent of antibiotics given by doctors to patients are either needless or incorrectly prescribed. Further, drug companies haven’t been willing to shell out money for research on better antibiotics because they can make more money on drugs that combat cancer or uncommon diseases. Reuters reports that in the United States, 23,000 people already die due to antibiotic resistance every year. Last year President Obama released the National Action Plan for Combating Antibiotic Resistant Bacteria, at which point the HHS said that it has been studying antibiotic resistance and is undertaking a ” coordinated public health response .” According to HHS and the USDA, a few ways to avoid antibiotic resistant bacteria are to thoroughly wash hands and produce, and properly cook all fish, meat, and poultry to kill bacteria.

Comments Off on Affordable Main Stay House in Austin keeps occupants cool without air conditioning

As anyone who has spent time in Texas during the summer knows, air conditioning can be your best friend. But MF Architecture wanted to create a home that didn’t need all that energy-sucking AC, but could still keep dwellers cool. To achieve this, they focused on the home’s site orientation, thermal bridge-free connections and airtightness. All of the openings were placed to welcome in plenty of light without bringing in the hot western sun. The pool was situated so that breezes could flow over the water and carry the cool relief indoors. Trees provide dappled light, and a large roof overhang keeps direct sunlight out of the home. The result is plenty of light without the heat. The house was designed with minimal amount of surfaces and openings and a sheltered entry and staircase clad in iron spot masonry. This entry volume demarcates the line between public, common and private spaces, which gives in inhabitants plenty of privacy, but also provides for ample entertaining space. The living room freely opens into the yard, and is devoid of visual and spatial obstacles. This is achieved by placing the service core along the east facade. Related: Four couples create a rustic cabin compound on a communal plot in Texas The open-plan layout allows natural light to fill the interior and reduce reliance on artificial lighting. Cross ventilation is enable by double-glazed operable windows and low-E coating. Advanced insulation helps keep the house cool in the summer. Despite its sleek, energy-efficient design features, the house was relatively cheap to construct-only $250 per square foot. + Matt Fajkus Architecture Photos by Charles Davis Smith , Allison Cartwright , Bryant Hill , Matt Fajkus
