Comments Off on This edible, plastic-free packaging is grown from kombucha starter

Polish design student Roza Janusz has created Scoby, an eco-friendly alternative to plastic packaging that is easily grown with the same methods used to make kombucha . Created from fermented bacteria and yeast, the organic membrane can be used to store a variety of lightweight foods like seeds, nuts, or even salads. The zero-waste food packaging is completely biodegradable and can also be eaten after use. Developed as part of her graduate project for industrial design at the School of Form in Poznan, Poland, Roza Janusz’s Scoby was created to help farmers grow their own zero-waste packaging. Using bacteria and yeast as a base for kombucha, Janusz then uses the liquid to grow the biodegradable membrane in a shallow container. After about two weeks of adding sugars and other agricultural waste to ferment the material, a membrane forms on the surface and can be harvested. “Scoby is grown by a future farmer not only for the production of packaging , but also because of the valuable by-product, which is, depending on the concentration, natural fertilizer or probiotic drink,” says Roza Janusz. “So maybe the packaging production will no longer litter the environment, and it will even enrich it.” Related: DIY: How to brew kombucha at home The lightweight and translucent material is easily malleable and can be shaped to fit a variety of foods to prevent spoilage. Thanks to the edible packaging’s low pH, Scoby has a long shelf life that can even be extended if it’s used to store acidic food products like nuts. The material can also absorb the flavors of the food it stores. Roza Janusz plans to explore Scoby’s commercial possibilities in the near future and recently submitted her design for the Golden Pin Concept Design Award 2018 . + Roza Janusz

Comments Off on Geologists discover bacteria that turns small bits of gold into solid nuggets

Geologists in Queensland, Australia have discovered a unique type of bacteria that forges small bits of gold into solid nuggets. The discovery could allow mining companies to reprocess previously undesirable gold into market-ready products, and transform the ways in which gold-containing electronics are disposed. “In electronic waste, there’s a lot of gold,” University of Adelaide associate professor Frank Reith told Australian Broadcasting Corporation (ABC) . “We need a technique without impact to health or community or environment to [recover] the noble metals that are in everyone’s smart phone or computer.” Current techniques to do so are not nearly as sustainable as they need to be, but that could change if the bacteria proves an effective scalable tool. In 2016, electronic waste, which includes disposed phones , computers, and televisions, contained $84 billion worth of recoverable materials, including $29 billion worth of gold. Reith and his team are collaborating with New Zealand -based Mint to craft a solution to this problem that utilizes the special gold-molding bacteria. “We’re working with electronic waste as a feedstock, and are piloting a process that uses microbes as a method of purifying precious metals from the mix of other metals that old circuit boards contain,” Mint chief strategy officer Dr Ollie Crush told ABC . Related: This jewelry is made with upcycled gold from Dell computers The bacteria works by filtering out other metals and piecing together gold nuggets, one grain at a time. The process of recycling gold could take between 17 and 58 years, which, in geological time, is no time at all. The process would need to be sped up considerably for it to be more widely applied throughout the world. However, the promise of capturing what otherwise would be lost wealth is enticing. “If you can make a recoverable resource from those parts, then you’re adding to the bottom line of any mine,” said Reith.

Flesh-eating bacteria in Australia might be spread by mosquitoes

Comments Off on Flesh-eating bacteria in Australia might be spread by mosquitoes

Cases of infections from a flesh-eating bacteria seem to be increasing in Australia . The bacteria Mycobacterium ulcerans can bring about Buruli ulcers, non-healing sores that slowly grow bigger. The ulcers are already a huge health issue in West Africa , and now Australia seems to be experiencing more cases. Scientists aren’t quite sure how humans get infected – though they suspect either possums or mosquitoes . Victoria, Australia saw 89 reported cases of Buruli ulcers in 2014. In 2015, that number increased to 107, and in 2016 it was 182. Already, as of this month in 2017, there have been 159 reported cases, according to Allen Cheng, professor in infectious diseases epidemiology at Monash University , who wrote an article on the flesh-eating bacteria for The Conversation. Related: This billboard imitates human sweat to snare mosquitoes 32 countries in West Africa have seen cases of Buruli ulcers, which grow larger usually on arms or legs for weeks or months. Advanced infections sometimes result in amputation, and in the past people thought surgery was necessary to treat the ulcers. Now, most cases in Australia can be cured with antibiotics , and there’s a trial in Africa testing treatment with antibiotics. It’s not clear how people get infected, although Cheng said circumstantial evidence seems to point towards mosquitoes. The bacteria can be found in the insects, and infections often occur on exposed areas of the body where mosquitoes bite. But researchers also discovered possums, and their feces, seemed to be infected where there have been human cases. Cheng also pointed out that infections happen in areas of the world with different animal and mosquito species. He said early diagnosis is key; the infection is easier to treat before it spreads, but does grow slowly. He recommended asking a doctor about unexplained sores or lumps, especially if they persist for a long time. And even though we can’t say for sure if mosquito bites do spread the bacteria, Cheng recommended mosquito repellents and covering up skin as a way to try and prevent infection.

These cyborg bacteria are better at photosynthesis than plants

Comments Off on These cyborg bacteria are better at photosynthesis than plants

Could cyborg bacteria generate clean power in the future? Researchers at UC Berkeley covered bacteria with small semiconductors that function like solar panels in order to see how much of the sun’s energy they could capture. The cyborg bacteria have a solar efficiency of 80% – which is four times greater than commercial solar panels and six times greater than the chlorophyll plants use in photosynthesis . Researchers in Peidong Yang’s laboratory gave the nonphotosynthetic bacterium Moorella thermoacetica cadmium, and the bacteria’s natural defense allowed it to produce cadmium sulfide crystals which accrued on the outside of their bodies and essentially acted as mini solar panels. The bacteria normally can produce acetic acid – which can be used for fuel, plastics, or pharmaceuticals – with carbon dioxide (CO2). But using their tiny solar panels, they were able to create acetic acid more efficiently with CO2, light, and water. Related: Cambridge scientists use light and plants to make cheap, clean hydrogen Kelsey Sakimoto of Harvard University , a past member of Yang’s group, told the BBC, “It’s shamefully simple, we’ve harnessed a natural ability of these bacteria that had never been looked at through this lens…You grow them in their liquid broth and you just add small aliquots of cadmium solution and you wait a couple of days and out pops these photosynthetic organisms. It’s all very simple, mix-in-a-pot chemistry .” Artificial photosynthesis techniques can be expensive, but big vats of liquid, in which the bacteria can be kept in sunlight, are really all that’s needed for this new process, so it could work well even in rural areas or developing countries . The self-replicating, self-regenerating bacteria offer a zero-waste technology, according to UC Berkeley.

Inexpensive new battery generates power with just a drop of saliva

Comments Off on Inexpensive new battery generates power with just a drop of saliva

In addition to aiding digestion, it turns out saliva can also power batteries. Researchers at Binghamton University discovered this while inventing a small, paper-based battery that generates energy when mixed with a drop of saliva. The batteries, which are more like tiny microbial fuel cells, are inexpensive to make and could be used in natural disasters and remote settings where on-demand power is hard (if not impossible) to come by. As a result, access to medical care and screenings in rural settings could improve. Binghamton University Electrical and Computer Science Assistant Professor Seokheun Choi spent the past five years developing the micro-power sources. His ultimate goal was to find a way to power medical diagnostic tests in poverty-stricken regions; finally, he succeeded at developing paper-based bacteria -powered batteries “On-demand micro-power generation is required especially for point-of-care diagnostic applications in developing countries,” said Choi. “Typically, those applications require only several tens of microwatt-level power for several minutes, but commercial batteries or other energy harvesting technologies are too expensive and over-qualified. Also, they pose environmental pollution issues.” Related: Indian startup pioneers new battery swapping system for electric buses The batteries contain freeze-dried exoelectrogenic cells which generate power when saliva is added. Astonishingly, with just one drop of spit, the paper batteries can produce enough power for low-power biological sensors in just a matter of minutes. Eureka Alert reports that a benefit of freeze drying the cells is that they can be stored for a long time before use. This means they can be stocked in medical clinics around the world. An additional perk is that the required biological fluid (saliva) can be easily obtained anywhere, anytime. At present, the battery can only produce a few microwatts of power per square centimeter. However, Choi and his research assistant, Maedeh Mohammadifar, are working on boosting the output. In the future, the team hopes to make the paper batteries more robust so they can sustain devices other than LED lights when connected in a series. The paper, “A Papertronic, On-Demand and Disposable Biobattery: Saliva-Activated Electricity Generation from Lyophilized Exoelectrogens Preinoculated on Paper,” was published in Advanced Materials Technologies. + Binghamton University Via Eureka Alert Images via  Binghamton University , Pixabay

Superbug resistant to last-resort antibiotics found on US pig farm

Comments Off on Superbug resistant to last-resort antibiotics found on US pig farm

Antibiotic resistance is a looming public health concern expected to kill up to 10 million people annually by 2050. Now, in the latest worrying development in the United States, Ohio State University researchers have found a bacteria resistant to last resort antibiotics, called carbapenems, on a pig farm that is barred from using them. The pig farm followed what the researchers describe as “typical US production practices” by giving their animals the antibiotic ceftiofur. Newborn pigs receive the antibiotic when they’re born, and when males are castrated, they’re given another dose. Ceftiofur is part of the cephalosporin family, but kills bacteria in a manner comparable to carbapenems. Related: ‘Nightmare’ bacteria found in the U.S. resists all known antibiotics The Ohio State researchers collected samples from the pig farm for five months to discover the superbug, Enterobacteriaceae , which Natural Resources Defense Council expert David Wallinga described in a blog post as “one of the nastier superbugs.” The journal Antimicrobial Agents and Chemotherapy published the researchers’ study online this week. Study co-author Thomas Wittum told TIME, “How the [resistant bacteria] got onto the farm we really don’t know. But probably it was introduced from the outside from movements of wildlife, people, equipment, etc.” During the study the researchers didn’t discover the bacteria in the pigs, but Wittum told TIME they later did see the superbug in piglets and sows. He said, “…that is the concern: that it could happen on this or other farms .” What does this discovery mean for US agriculture? In 2012, the Obama administration established guidelines that will go into effect in January 2017. The guidelines would limit the use of antibiotics on farms, but they are voluntary. Meanwhile, according to Mother Jones, advisers to the new President-elect appear to be resistant to regulation when it comes to food production. The Centers for Disease Control and Prevention said the bacteria found on the pig farm already kills as many as 600 people every year.

99-million-year-old dinosaur tail found immaculately preserved in amber

Comments Off on 99-million-year-old dinosaur tail found immaculately preserved in amber

When a small, sparrow-sized dinosaur died about 99 million years ago, part of its tail was immaculately preserved in amber. Researchers who recently discovered the tail from a Hukawng Valley amber mine in Myanmar say it’s a notable find not only because it is the first dinosaur tail ever identified, but also because it is covered in feathers. Co-first author Lida Xing of China University of Geosciences found the amber piece in a Myanmar market in 2015, according to NPR . The Dexu Institute of Palaeontology agreed to purchase the specimen, and Xing and colleagues got to work scrutinizing it. Related: First dinosaur brain tissue discovered in 130-million-year-old fossil The dinosaur was likely a carnivorous coelurosaurus, part of a group that includes the mighty Tyrannosaurus , although the discovered dinosaur probably wasn’t very mighty itself. Scientists can tell it was tiny from the tail bone, which is a mere two millimeters across. Part of the mystery of dinosaurs with feathers is that many probably didn’t use that plumage to fly. The structure of the little dinosaur’s feathers instead resembles ornamental feathers seen on some modern birds . Scientists can see the way the feathers’ barbs bend means they’re far more flexible than feathers used for flight, and could have been employed to send signals or regulate the dinosaur’s temperature. The top of the feathers could have been dark brown, the scientists think, with the underside having no color at all. That or carotenoids – pigments responsible for orange, red, and yellow hues – may have brightened the underside feathers in life but broke down swiftly when the dinosaur died. Thrilled with the discovery, the scientists hope they might be able to find even more specimens in the future. With a conflict between the Kachin Independence Army – who currently possess the Hukawng Valley – and the Myanmar government hopefully coming to a close, scientists may be able to get more access to the amber mines, according to Xing. He speculated they might even find a whole dinosaur one day. 14 scientists from international institutions participated in a new study published by the journal Current Biology .
