Comments Off on 3D-printed ovaries let infertile mice give birth

Three-dimensionally printed organs are pretty old hat by now. But while the technology has been applied to everything from artificial ears to replacement brain tissue , working ovaries have been outside the realm of possibility—until now, that is. Scientists from Northwestern University’s Feinberg School of Medicine and McCormick School of Engineering have developed “bioprosthetic” ovary structures that allowed infertile mice to not only ovulate but also birth and nurse healthy offspring, according to a paper published this week in the journal Nature Communications . Composed of rapid-prototyped gelatin scaffolds, and primed with immature eggs, the bioprosthetic ovaries successfully boosted the hormone production necessary for restoring fertility in the mice, researchers said. “This research shows these bioprosthetic ovaries have long-term, durable function,” Teresa K. Woodruff, a reproductive scientist and director of the Women’s Health Research Institute at Feinberg, said in a statement. “Using bioengineering, instead of transplanting from a cadaver, to create organ structures that function and restore the health of that tissue for that person, is the holy grail of bioengineering for regenerative medicine.” Related: Organovo’s Bioprinter Technology Could Lead to 3D Printed Human Organs Woodruff and company plan to test the structures in pigs, with an eye toward human trials in the future. The technology could have significant implications for women with fertility issues, particularly cancer patients who often lose their ovarian function after intensive chemotherapy. “What happens with some of our cancer patients is that their ovaries don’t function at a high enough level and they need to use hormone replacement therapies in order to trigger puberty,” said Monica Laronda, co-author of the study and a former post-doctoral fellow in the Woodruff lab. “The purpose of this scaffold is to recapitulate how an ovary would function. We’re thinking big picture, meaning every stage of the girl’s life, so puberty through adulthood to a natural menopause.” + Northwestern University Photo by Duncan Hull

Comments Off on Extraordinary man builds 25 plastic bottle homes for refugees in Algeria

A Sahrawi refugee in Algeria is rebuilding lives – literally. Born and raised in the refugee camp in Awserd near Tindouf, 27-year-old Tateh Lehbib Breica is constructing disaster resistant homes using discarded plastic bottles – for himself and others. These recycled homes are specifically built to endure harsh desert conditions for an affordable price. It’s no easy feat to construct homes in a climate where temperatures can spike to around 113 degrees Fahrenheit. Sandstorms also prey on refugee shelters in five camps near Tindouf, Algeria, where people live after fleeing violence in the Western Sahara War over 40 years ago. But the area also faces destructive rainstorms – in 2015 heavy rains wrecked thousands of homes. Related: Mayor born in Syria converts abandoned Greek resort into a sanctuary for refugees Breica may have found a solution in old plastic bottles filled with sand. He has a master’s degree in energy efficiency after participating in a United Nations High Commissioner for Refugees (UNHCR) scholarship program. He’d intended to build a rooftop garden, growing seedlings in the bottles, but the circular shape of the energy efficient home he was building posed a challenge to that idea. He wondered what he could do with the bottles instead and recalled a documentary on building with plastic bottles he’d seen during his time at university. The plastic bottle homes can better withstand storms than adobe , mudbrick, or tent homes, and are water resistant. The homes have thick walls, and partnered with their circular shape, stand up better to sandstorms. Breica built the first bottle home for his grandmother, who was hurt while being carried to a community center to hunker down during a sandstorm. Working with UNHCR, Breica has built 25 homes so far. He’s earned the nickname Crazy with Bottles for his work. Although he’s won awards for his design, he said, “People still see me as the guy obsessed with recycling bottles and building unusual houses.” Via UNCHR Images © UNHCR/Russell Fraser

Fresh food prescriptions given to low-income patients to help combat disease

Comments Off on Fresh food prescriptions given to low-income patients to help combat disease

What if instead of prescribing medicine to treat a disease , doctors could prescribe fresh food to help prevent one? Geisinger Health System in Pennsylvania is testing their food prescription idea with Fresh Food Pharmacy, a service that currently provides diabetic, food insecure patients with recipes and nutritious fare. It turns out giving away healthy food for free is not only socially beneficial, but could ultimately save the healthcare system a decent amount of money. The Fresh Food Pharmacy brims with whole grains, fresh produce, lean meats and fish, greens, and low-fat dairy products. Patients aren’t just handed food, but provided a one-on-one meeting with a dietitian, recipes , and instructions on how to make nutritious meals. They receive enough food for five days. Related: HUMAN Healthy Vending Machines Fight Childhood Obesity by Offering Healthy Snacks Some people thought handing out free food might rack up a hefty price tag. But diabetes costs are greater than $240 billion a year in the United States. In contrast, Geisinger Health System will pay around $1,000 a year for each diabetes patient in the food pharmacy program. The Geisinger team is tracking hemoglobin A1C levels to help see how much the Fresh Food Pharmacy could save them. CEO David Feinberg estimates each point of decrease in hemoglobin A1C could save them around $8,000, and many of the around 180 patients in the pilot program have seen a drop of three points. America’s health care system today is often termed a disease care system instead; physician Mitesh Patel of The Wharton School at the University of Pennsylvania said, “We wait until people get sick and then spend a lot of resources helping them get better.” But he says the Fresh Food Pharmacy offers social and financial incentives to actually help people make a change in their own health. The Fresh Food Pharmacy has made a huge difference for Type 2 diabetes patient Tom Shicowich. He said he used to stop at Burger King or McDonald’s for dinner, or heat up a frozen meal. Now he cooks meals at home with his girlfriend. He’s lost around 45 pounds. And his A1C level has changed significantly. The threshold for Type 2 diabetes is above 6.5. Shicowich’s A1C level was almost 11 a year ago; today it has plummeted to the high-six range. Via NPR Images via Peyri Herrera on Flickr and Geisinger Health System

MIT researchers invent an ingestible battery powered by stomach acid

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
