Comments Off on Study estimates sea level rise two times worse than worst-case scenario

Sea level rise is a serious threat, but a new report argues that it may be far worse than even the current worst-case estimates. The study, published in the Proceedings of the National Academy of Sciences on Monday, estimates that there is a 5 percent chance the sea level will rise between 2 feet and 7.8 feet within the next century. This is more than twice what was recently predicted by the Intergovernmental Panel on Climate Change. Although 5 percent might seem like a small probability, the researchers are quick to point out that is a one in 20 chance, and this should not be ignored by governments and infrastructure planners. Scientists focused their research on predicting the impact of ice melting in Greenland and Antarctica if the world warms by 5 degrees. Under the Paris Agreement, 185 countries pledged to limit global warming to just 1.5 degrees Celsius, but radical changes would have to be made and sustained in order to come close to this ambitious goal. “We should not rule out a sea-level rise of over 2 meters if we continue along a business-as-usual emissions trajectory,” Jonathan Bamber, lead author from the University of Bristol,  told USA Today . According to the researchers’ predictions, such a rise in sea levels would be globally catastrophic. Coastal cities like Miami and New York are especially vulnerable, as are major agricultural areas like the Nile Delta. Small islands in the Pacific and Caribbean would be devastated, and an estimated 187 million people would be displaced. To put this into perspective, about 1 million people have been displaced by the Syrian refugee crisis. Bamber said , “What we decide to do collectively as a species politically, globally, over the next decade is going to determine the future of the next generations in terms of the habitability of the planet and what sort of environment they live in.” Via EcoWatch , CNN and USA Today Image via NASA

Farming insects too much too fast could create an environmental disaster

Comments Off on Farming insects too much too fast could create an environmental disaster

The potential of insects as an alternative source of protein is promising. But this week, Swedish scientists warned that more research is needed on the environmental impact of mass rearing insects before large-scale production begins if we want to avoid a potential environmental disaster. Writing in the Trends in Ecology & Evolution journal, the researchers explained that there is currently an “overwhelming lack of knowledge” about insects, especially basic things like what they need for housing and food, how to manage their waste and which are the most suitable species for mass rearing. Related: Modular Cricket Shelter grows edible insects in Brooklyn The UN Food and Agriculture Organization (FAO) said that more than 1,900 species of insects are edible, but the researchers believe that we first need to get answers to those basic questions, so we don’t “risk creating an industry that replaces one environmental problem with another.” Both nutritionists and scientists have advocated insects as being a sustainable and cheap source of protein to feed our constantly growing population. They also have benefits like being high in vitamins, fiber and minerals. Insects produce fewer greenhouse gases than pigs or cattle, and they require a lot less land and water. Businesses have already started to enter the world of edible insects, producing things like sweet potato soup made with bugs, burgers made of buffalo worms and DIY insect farms. But this might be too much too fast, according to Asa Berggren, a conservation biologist at the Swedish University of Agricultural Sciences and the paper’s co-author. “How do you produce the feed they eat, where do you produce it, what do you use? There are so many questions,” Berggren said. “Are we going to use fossil fuels for heating and cooling the facilities (where insects are grown)? What about transportation?” She went on to say that one of the biggest threats to both natural and production systems is invasive species . There could be a big problem if insects are accidentally released in a country where they are imported. Other concerns include whether or not farmed insects that get sick will transmit diseases to consumers, and there is also a question of animal welfare . Berggren admitted that there could be a lot of insects that are good for us to eat, but further research is important. Via Reuters Image via Primal Future ( 1 , 2 )

Comments Off on An itty-bitty tiny home on wheels is pretty in pink

Designed by architect Joshua Woodsman of Pin-Up Houses , this bright pink tiny home is one of the most vibrant we’ve ever seen. Adding to its whimsical exterior, Magenta is a prefabricated tiny home on wheels that has a living space of just 66 square feet. However, within that tiny space are plenty of creature comforts that make it a fabulous home for living life on the road. According to the team from Pin-Up Houses, the vibrant Magenta is “a manifesto of temporary independent housing, against debt and mortgages.” Built on a flat trailer, the tiny home was designed for people who want to live on the road with a transportable but comfortable home. Accordingly, Magenta was built with extremely lightweight materials, waterproof plywood and spruce beams. Polystyrene insulation was installed on every side of the home, keeping it cozy and warm in the winter months and cool in summertime. A large window lets natural light into the living space. Related: ‘France’ is a $1,200 tiny house that snaps together in just 3 hours The interior space is compact, but the designers were able to outfit it with almost all of the basic amenities. There is a comfy sofa bed along with a small kitchenette that has a water tank, a gas cooker, a sink and plenty of secure drawers. A dining table with two chairs offers a nice place to eat and work. When nature calls, a humble chemical toilet was installed in a tiny water closet. Additionally, there is a heating stove that keeps the place nice and toasty. The home was built with a pitched roof, which gives the interior extra space for storage. Besides the custom built-in furniture , such as pull-out drawers under the sofa, there are multiple stretched nets hung on the walls for stashing away personal items. There is also a larger net that spans the length of the ceiling, adding a ton of space for storing sporting equipment, clothing, books and more. + Pin-Up Houses Images via Pin-Up Houses

Scientists find air pollution leads to a significant decline in cognition

Comments Off on Scientists find air pollution leads to a significant decline in cognition

It turns out pollution affects more than just the environment. New research shows there might be a correlation between significant air pollution and cognitive decline in humans. Scientists hope their research will lead to changes in how countries deal with excessive air pollution, especially in heavily populated urban areas. Over the course of several years, more than 25,000 people hailing from 162 different counties in China were studied. The researchers published their findings in the Proceedings of the National Academy of Sciences and are calling for China to reform its pollution policies. The researchers believe China can significantly increase the population’s education level by adhering to the U.S. EPA guidelines. So, how did researchers link pollution with cognitive decline? The scientists performed verbal and math exams on all of the subjects in 2010 and again in 2014. The data from the exams were then compared between the years, and the team linked these changes to  air pollution . The researchers found that the older subjects performed worse on the tests, which led the team to believe that pollution has a bigger effect on brains as people age. The study also showed that individuals with little education were more affected by pollution, possibly because they typically work outdoors. Although the researchers were confident in linking pollution and cognitive decline, they are not sure why it is happening. Xi Chen, study co-author and professor of health policy at Yale, believes that pollution could be harming white matter in the brain , a region that controls communication within this important organ. James Hendrix, the head of the Alzheimer’s Association’s Global Science Initiative, disagrees. Hendrix does not believe the researchers have any evidence to suggest that pollution is damaging white matter. He also argues that associating air pollution with cognitive deterioration is difficult, because there are too many other factors at play. Either way, it’s clear that air pollution is negatively impacting our health and our planet. + Proceedings of the National Academy of Sciences Via NPR Images via Fredrik Rubensson and  Nicolò Lazzati

Breast cancer spread connected to amino acid in asparagus

Comments Off on Breast cancer spread connected to amino acid in asparagus

Scientists have linked the spread of the disease breast cancer in mice to a compound that’s in asparagus and several other foods, The Guardian reported . Studies with mice revealed asparagine drives the advance of the cancer , and when researchers reduced asparagine, the amount of “secondary tumors in other tissues” dropped. Cancer Research UK Cambridge Institute director Greg Hannon told The Guardian, “This is a very promising lead and one of the very few instances where there is a scientific rationale for a dietary modification influencing cancer.” Research with mice showed the amino acid asparagine is important for breast cancer to spread, and scientists think the process could be similar in humans. Researchers found that blocking the amino acid hampered the spread of the cancer. Hannon said in a statement , “It could be that manipulating levels of asparagine in the body might be used as a way to boost a patients’ cancer treatment.” Related: Many anti-aging products contain ingredients that can cause breast cancer The researchers blocked asparagine in mice tested, which had an aggressive type of breast cancer, to reduce the cancer’s ability to spread with the drug L-asparaginase. Giving the mice a low-asparagine diet worked to a lesser extent, according to The Guardian. There’s still a lot work to be done. The Cancer Research UK Cambridge Institute cautioned research is in the early stages and “doesn’t form the basis for DIY diets at home.” This work also doesn’t seem to offer a cure for cancer; per the press release, “So far the story suggests that lowering asparagine levels blunts the ability of cancer cells to spread in mice, but doesn’t affect the original tumor.” Lowering asparagine didn’t prevent breast tumors from forming, the researchers found. Hannon said, “The difficulty is finding ways to study this in the lab that are relevant to patients. It’s a challenge, but I think it’s worth pursuing.” The journal Nature published the research online this week . 21 scientists at institutions in the United Kingdom, Canada, and the United States contributed. + Cancer Research UK Cambridge Institute + Nature Via The Guardian Images via Stephanie Studer on Unsplash and Tambako The Jaguar on Flickr

Tiny treadmills for turtle hatchlings help scientists evaluate their stamina

Comments Off on Tiny treadmills for turtle hatchlings help scientists evaluate their stamina

When baby sea turtles are born, within their first 24 hours they make the journey from nest to ocean . The trek which should take a few minutes sometimes lasts hours in urban settings where artificial light can disorient the hatchlings. Two Florida Atlantic University (FAU) scientists employed wee treadmills and little swimsuits to dig into the turtles’ swimming performance after crawling for so long – and they were surprised by what they found. Speed is crucial for turtle hatchlings, who face dangers on their way to the ocean. Their survival “depends heavily on their ability to swim,” according to FAU. But in urban settings, excess light from streets and buildings can draw the babies away from the ocean and towards land – where they might get run over by traffic, drown in a pool, or be eaten by a predator. Biological sciences associate professor Sarah Milton said in a statement, “What prompted our study was the desire to understand what happens to these hatchlings after they spend hours crawling on the beach because they are disoriented. We wanted to know if they would even be able to swim after crawling 500 meters or more, which could take them as long as seven hours to complete.” Related: Police Officer Saves Nearly 100 Baby Sea Turtles in Florida Milton and graduate student Karen Pankaew conducted what FAU described as the “first study on disorientation to examine the physiological effects of extended crawling and swimming performance.” They gathered 150 hatchlings from 27 loggerhead and 18 green turtle nests in Palm Beach County, Florida . The hatchlings walked on tiny treadmills before swimming in a tank in a specially designed swimsuit. The scientists measured oxygen consumption, lactate accumulation, and swimming breathing and stroke rates. Field studies supplemented laboratory observations. The hatchlings were placed into the ocean in their natural habitats shortly after collection. The study results completely surprised the researchers, according to Milton, who said, “We were expecting that the hatchlings would be really tired from the extended crawling and that they would not be able to swim well. It turned out not to be the case and that they are in fact crawling machines. They crawl and rest, crawl and rest and that’s why they weren’t too tired to swim.” She also said the study offers a scientific basis to back up lighting ordinances during hatching season. The Journal of Experimental Biology published the study in November. Via Florida Atlantic University Images via Pixabay and Jay Paredes

MIT battery that inhales and exhales air can store power for months

Comments Off on MIT battery that inhales and exhales air can store power for months

Could this air-breathing battery help solve energy storage woes? 10 Massachusetts Institute of Technology (MIT) researchers developed the battery capable of storing electricity for months for around one fifth of the cost of comparable technologies. MIT professor Yet-Ming Chiang said, “This battery literally inhales and exhales air , but it doesn’t exhale carbon dioxide , like humans – it exhales oxygen .” MIT says their air-breathing battery could help renewable energy , like solar and wind, be more practicable for the grid . Their rechargeable flow battery costs a fraction of current technology, and can store power for long periods of time, with zero emissions and few location restraints. Related: Former Tesla executives to produce battery “with significantly lower carbon footprint” Sulfur dissolved in water comprises the battery’s liquid anode. What MIT described as an aerated liquid salt solution in the liquid cathode brings in and lets out oxygen. According to the institute, “Oxygen flowing into the cathode causes the anode to discharge electrons to an external circuit. Oxygen flowing out sends electrons back to the anode, recharging the battery.” The cost of the anode, cathode, and electrode materials in the battery is around 1/30 that of lithium-ion batteries , according to MIT. If the battery system was scaled up, it could store electricity for around $20 to $30 per kilowatt-hour – compare that against today’s batteries, which are around $100 per kilowatt-hour, at least. Right now, the prototype is about as big as a coffee cup. But Chiang said flow batteries are highly scalable. This new technology could compete with pumped hydroelectric storage systems, though, since the MIT system is more compact, it could be deployed in more locations where renewable energy is being generated. As solar and wind energy production can be intermittent, the battery could store the energy they generate to offer a reliable source of power. The journal Joule published the research this week.

Comments Off on Doctor warns falling sperm counts could lead to human extinction

Will our lifestyle lead to our extinction ? New findings from an international team of eight researchers indicate sperm counts in men from North America, New Zealand, Australia, and Europe have halved in under 40 years. Lead author epidemiologist Hagai Levine of the Hebrew University of Jerusalem told the BBC, “If we will not change the ways that we are living and the environment and the chemicals that we are exposed to, I am very worried about what will happen in the future.” Sperm count studies have been controversial in the past. This recent one, published this week in the Oxford Academic journal Human Reproduction Update , is one of the biggest assessments ever undertaken, according to the BBC. Researchers pored over 185 studies between 1973 and 2011. Levine detected a 52.4 percent decline in sperm concentration and 59.3 percent drop in total sperm count in the men from those regions of the world listed above. The rate of decline continues and may even be increasing, according to the researchers. They didn’t see the same decline in men from Africa, Asia, or South America, but said there have been fewer studies from these regions. Related: Alarming new study suggests Zika virus could cause infertility in men Levine told the BBC, “Eventually we may have a problem, and with reproduction in general, and it may be the extinction of the human species.” Skeptics say a large proportion of past studies that have pointed to sperm count drops have been flawed, such as only including men who have gone to fertility clinics, and would be likely to possess low sperm counts. But the researchers involved in the new study said they accounted for some of the flaws. Professor Allan Pacey of Sheffield University told the BBC, “I’ve never been particularly convinced by the many studies published so far claiming that human sperm counts have declined in the recent past. However, the study today by Dr. Levine and his colleagues deals head-on with many of the deficiencies of previous studies.” Other scientists praised the quality of the new study but said it may be too soon to come to the conclusion that humans could be on the path to extinction. Researchers at institutions in Denmark, the United States, and Spain were also part of the research. Via the BBC Images via Wikimedia Commons and Pixabay

Comments Off on BatBnB unveils line of stylish (scientifically designed) homes for our flying friends

Airbnb disrupted the human housing world, now BatBnB is doing the same for bat housing. We all pretty much know that boxes are a stellar way to attract bats, but let’s be honest, they aren’t exactly good looking. That’s why we’re loving the elegantly designed BatBnB homes, which are attractive enough to display front and center at your home. They’re also designed based on decades of research, so they’re the perfect space for our flying friends. It’s basically like a piece of art for your yard that also boosts conservation efforts. Created by Harrison Broadhurst, architectural designer at Nomi Design and director of customer success at MakeTime   Christoper Rännefors , BatBnB provides a safe place for bats to nest, sleep and stay. Unlike other bat houses, BatBnB is incredibly stylish, so instead of tucking it in some remote corner, you’ll want to display it proudly. There are three style options available in the standard size, plus a mammoth size, so you can find the right one to suit your home. It’s finally the perfect bat house for design lovers. Of course, BatBnB isn’t just snazzy on the outside. It is also thoughtfully designed to be the ultimate space for bats, with grip chambers, proper ventilation and the ideal sizing. It’s so well-designed that it is endorsed by bat experts like executive director of the Organization for Bat Conservation  Rob Mies , who is basically the Beyonce of the bat world. Researchers will also team up with BatBnB owners to collect vital information that will help bats recover from devastating white nose syndrome. Related: 7 Million Bats Killed by White Nose Syndrome: How You Can Help “I’ve studied bats for more than 50 years, led worldwide conservation efforts for bats, and in fact founded the North American Bat House Research Project. With today’s improvements, properly constructed and located bat houses are achieving close to 90% success. I personally helped develop the Bat BnB product line and am delighted to endorse it for its ideal construction and attractive design,” said noted bat expert Merlin Tuttle. Bats are struggling across the US because of habitat loss and  white nose syndrome . It doesn’t help that many people fear bats for being dangerous or diseased, a reputation that is decidedly undeserved. BatBnb is hoping to change that. “We want to help people value bats rather than fear them — those ugly poorly designed models on the market just don’t spark that conversation,” said Rännefors. With climate change making winters shorter, we are seeing more mosquitos all year long, and one of the best ways to naturally control pesky bugs is with predators like bats. Bats are also instrumental in maintaining a healthy environment by helping to fertilize and pollinate plants – in addition to the thousand mosquitoes a single bat can eat every hour . Help BatBnB become a reality, and help change the conversation around bats, by funding the project on Indiegogo . + BatBnB + BatBnB on Indiegogo

We’ve made enough plastic trash to bury Manhattan under 2-miles of the stuff

Comments Off on We’ve made enough plastic trash to bury Manhattan under 2-miles of the stuff

Whether you get an iced latte to-go in the morning, your restaurant leftovers in a plastic takeaway container, or forget to take a reusable bags to the store, there are numerous ways  disposable plastic  adds up –   and that is a huge problem. According to the first global analysis of the production of plastics, humans now produce more plastic than anything else and, as a result, have created 8.3 billion tonnes of the stuff since the 1950s. If the trend continues, humans will eventually bury the planet in plastics, which require hundreds — if not thousands — of years to decompose. The study was published in Science Advances and unearthed some dizzying facts. For instance, around 79 percent of the plastic produced ends up in landfills, where it is simply buried and forgotten. Additionally, a large percentage of this waste goes into the oceans where it contaminates the environment , often times poisons or chokes wildlife, and breaks down into tiny pieces, which later collect in giant convergences such as the Great Pacific Garbage Patch . The study also found that only 9 percent of all plastics are recycled, and a further 12 percent are incinerated. “The only way to permanently eliminate plastic waste” is to burn or melt it down, the authors wrote . “Thus, near-permanent contamination of the natural environment with plastic waste is a growing concern.” For the study, the researchers looked at various kinds of plastics, from resin to fibers. They deduced that production has increased from around 2 million tonnes (2.2 m tons) a year in 1950 to an astonishing 400 million tonnes (440 m tons) in 2015. Plastic is now the most produced man-made material, with the exception of items such as steel and cement. However, unlike those two industrial materials which are put to use for decades, plastic is single-use, therefore, is most often discarded right away. The researchers make it clear that while it is not plausible to completely eliminate plastic from the modern world, production and use needs to decrease dramatically to benefit the ecosystem as a whole. “Most plastics don’t biodegrade in any meaningful sense, so the plastic waste humans have generated could be with us for hundreds or even thousands of years,” said Jenna Jambeck, who co-authored the study. “Our estimates underscore the need to think critically about the materials we use and our waste management practices.” The advice is spot-on, considering a recent paper found the micro plastics were present in every marine animal which was sampled in Australia — even those thought to be inaccessible. Related: Scotland bans plastic bags, spares landfill 650 million bags in just one year To reduce your dependence on plastic, you can buy whole, unprocessed foods and biodegradable soaps in bulk and keep them in mason jars at home, remember to take your reusable bags to the grocery store and farmer’s market and take advantage of thrift store offerings (or similar apps which connect you with second-hand goods) to reduce waste and needless packaging. Making this effort will help reduce the amount of plastic in the environment and, as a result, ensure a habitable environment exists for future generations. + Science Advances Via LA Times Images via Depositphotos and   Pixabay
