Comments Off on Japanese train barks and snorts to protect deer from harm

Researchers from the Railway Technical Research Institute in Japan have equipped a train with a speaker that plays the sounds of dogs barking and deer snorting to protect deer from harm. A three-second deer snort is played first to catch the attention of any nearby deer, followed by 20 seconds of dog barking to scare the animals away. So far, the late-night tests of the anti-deer device have proven successful, resulting in a reduction in deer sightings by half. If further evidence supports the practice, it may be adopted more broadly, though the deer-dog combo noise would likely not be blasted in residential areas. Deer fatalities by train have proven to be a challenge because the animals are attracted to train tracks. To meet their iron dietary needs, deer lick the tracks to pick up iron filings that have formed through friction between the train wheels and the tracks. The transport ministry of Japan reports that in 2016, there were 613 cases of trains hitting deer and other wild animals, a record high number, with each collision resulting in delays of 30 minutes or more. Related: Utah plans $5 million wildlife bridge over deadly I-80 highway There have been several attempts to make railroads less attractive spots for deer, including spraying lion feces along the tracks. This plan was abandoned after rain washed away the animal waste products almost immediately. Another more successful plan involved the use of ultrasonic waves, projected when a train is coming to deter animals , then dropped when the coast is clear to regulate the use of the train tracks. Trials of this technology resulted in a notable decrease in deer deaths. For this, railway employee Yuki Hikita was awarded Japan’s Good Design Award in December 2017.

Comments Off on Norway shoots for 100% electric short-haul flights by 2040

More than 50 percent of new car sales in Norway were electric vehicles in December, according to Electrek . Now the country aims to take the electric revolution to the skies. Norwegian airports public operator Avinor wants all their short-haul flights to be electric in just over 20 years. CEO Dag Falk-Petersen told Agence France Presse (AFP) they’re hoping “to be the first in the world” to switch over to electric air transportation . Every short-haul airliner should be electric by 2040 in Norway, Avinor said this week. Falk-Petersen told AFP, “We think that all flights lasting up to 1.5 hours can be flown by aircraft that are entirely electric.” He said that would include all domestic flights and trips to nearby Scandinavian capitals. Related: Eviation Aircraft unveils all-electric plane with 600-mile range 2.4 percent of Norway’s greenhouse gas emissions come from domestic air transportation – and when international routes are taken into account the figure is over double that. Falk-Petersen told the AFP, “When we will have reached our goal, air travel will no longer be a problem for the climate , it will be a solution.” There are other benefits to electric flight besides lowered carbon emissions – such as reduced operating costs. Falk-Petersen also said electric flight would halve noise levels at least. Avinor will explore intermediary technologies, like hybrid fuel-electric options or biofuels , before making the switch to all-electric. The company recently teamed up with the Norwegian Air Sports Federation to purchase the first electric aircraft in Norway from Pipistrel . The Alpha Electro G2 is a two-seater aircraft with a range of 130 kilometers, or just over 80 miles. Falk-Petersen said in Avinor’s press release on the purchase that lower operating costs could have an impact on ticket prices as well. AFP reported Avinor also aims to start a tender offer to trial a commercial route with a 19-seat electric plane beginning in 2025. Via Agence France Presse and Electrek Images via Avinor ( 1 , 2 )

Comments Off on Hundreds of dead sharks wash up on the shores of the Persian Gulf

Officials in Iran came across a gruesome sight this week: hundreds of dead sharks washed up on shore . The cause isn’t some natural phenomenon – hunters have been illegally capturing the sharks, sawing off the fins and tossing them back into the water, where they got caught up in currents and eventually wound up on land. Hossein Delshab, an official in the city of Bushehr, told a local news agency that hundreds of dead sharks had recently washed up on the shores of Shif island, raising “an alarm about the extinction of sharks” in the area. Related: 512-year-old Greenland shark may be the oldest living vertebrate on Earth Although shark fishing has been banned in the area since 2014, high demand for their prized fins has made hunting them worth the possible fine if the poachers are caught. Violators can be fined up to $7,000. But because it is believed that shark fin can help with sexual disorders, they are a popular item in local markets.

Comments Off on World’s fastest bullet train can travel between Beijing and Shanghai in 4.5 hours

Traveling between Shanghai and Beijing can take more than 12 hours by car, or over eight hours on public transportation . But a new bullet train could slash those travel times. China recently launched the fastest bullet train in the world that travels at a speed of 217 miles per hour. This month, China launched the world’s quickest bullet train in Beijing. The service is called Fuxing and will travel the route between the country’s capital and Shanghai – a 777-mile trek – in around four hours and 30 minutes. Related: China takes on the Hyperloop with a supersonic ‘flying train’ This isn’t the first time China has run a 350 kilometer per hour (km/h) bullet train. They first launched a train that travels at that speed in August 2008, but lowered speed limits in 2011 to 186 miles an hour after a two-train crash close to Wenzhou that killed 40 people. A signaling failure caused the crash, according to Al Jazeera. The BBC said Fuxing trains have an improved monitoring system that can slow the trains down and stop them if there’s an emergency. Now the Chinese government is thinking of building more bullet trains, and taking their technology abroad. Experts wonder about the economic benefits of the super fast bullet train – estimates from international think tanks indicate it could cost 90 percent more to construct lines for 217 mph trains than for those that only travel at 155 mph. Economics professor Zhao Jian told Al Jazeera, “The purpose of raising the speed is mainly symbolic. The train is the fastest in the world, which implies the strength of Chinese train technology and science.” According to The Telegraph, the country has laid over 12,400 miles of high-speed rail , and aim to add 6,214 more miles by 2020. Along with looking to take their technology overseas, according to the BBC, China’s rail operator might even be looking into how to upgrade tracks so that trains could travel at speeds close to 250 mph.

Comments Off on Video footage of rare all-white moose in Sweden

The rare appearance of a white moose is being celebrated by animal enthusiasts worldwide, as the majestic animal is estimated to be one of just 100 living in Sweden . Hans Nilsson, who has been tracking the elusive creature for three years, captured the footage on August 11 in the province of Varmland. As soon as it was uploaded, the video went viral. The BBC reports that the white moose is not albino but lacks color due to a genetic mutation. True albino animals are unable to produce melanin and have pink or red eyes. Animals with leucism, on the other hand, have a snowy white coat and dark-colored eyes. Moose are extraordinary animals , standing approximately 6.5 feet high at the shoulder. Some moose can weigh up to 1,800 pounds, and males have massive antlers that can span up to 6 feet end to end. Moose can also run up to 35 miles per hour.

Doctor warns falling sperm counts could lead to human extinction

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

Scientists warn thawing soil could suddenly unleash deadly pathogens unseen in centuries

Comments Off on Scientists warn thawing soil could suddenly unleash deadly pathogens unseen in centuries

Humans have fought viruses for centuries. We struck a temporary winning blow with the discovery of penicillin, but now we’re watching bacteria develop antibiotic resistance . But what if we were exposed to viruses that have been dormant for millennia? As climate change melts permafrost , the frozen soil could suddenly release ancient, deadly bacteria and viruses that humanity hasn’t had to deal with for thousands of years. 2016 saw a case of an illness trapped inside ice being released to harm people . A 12-year-old boy died and around 20 people were hospitalized with anthrax in August 2016 in the Siberian tundra. Researchers think the anthrax came from a reindeer that died more than 75 years ago and was trapped under permafrost, but when that permafrost thawed in a 2016 heat wave, the anthrax was released. And researchers fear this may not be the last time such an event occurs. Related: Dramatic disintegration of Canada permafrost threatens huge carbon release Jean-Michel Claverie, an evolutionary biologist at France’s Aix-Marseille University, told the BBC, “Permafrost is a very good preserver of microbes and viruses, because it is cold, there is no oxygen, and it is dark. Pathogenic viruses that can infect humans or animals might be preserved in old permafrost layers, including some that have caused global epidemics in the past.” Over a million reindeer perished due to anthrax in the early 20th century. Most of their carcasses rest near the surface in 7,000 burial grounds in Russia. But even more than the anthrax, researchers fear other diseases that might be lurking in the permafrost. Scientists found pieces of RNA from the Spanish flu in bodies buried in the Alaskan tundra in mass graves. They think the bubonic plague and smallpox could hide in Siberian permafrost. But some bacteria won’t come back to life. So some people argue we should be more concerned about threats we know for sure climate change will unleash. Claverie says there’s a non-zero probability dormant microbes could come back to life and harm us. He told the BBC, “How likely that is is not known, but it’s a possibility. It could be bacteria that are curable with antibiotics, or resistant bacteria, or a virus. If the pathogen hasn’t been in contact with humans for a long time, then our immune system would not be prepared.” Via the BBC Images via NPS Climate Change Response on Flickr and Pixabay

World officials entreat Trump to stay in Paris agreement

Comments Off on World officials entreat Trump to stay in Paris agreement

President Donald Trump’s policies don’t just impact the United States. As climate change grows increasingly dangerous, executive orders on the Clean Power Plan and fossil fuel development in a top greenhouse gas-producing country have consequences for other countries as well. The Guardian spoke with world leaders, some of whom were involved in the 2015 Paris climate deal , who agree it would be disastrous if Trump were to pull America out of the historic agreement. Trump threatened to pull out of the Paris agreement on the campaign trail, and has yet to follow through. But he’s taken shots at the environment anyway, by rolling back pollution rules including Barack Obama’s Clean Power Plan. He could make a decision on the agreement as soon as this week, and former Brazilian environment minister Izabella Teixeira, instrumental in Paris, said the situation reminds her of when George W. Bush pulled away from Kyoto protocol. Related: ExxonMobil exhorts White House to keep Paris agreement Former head of climate policy in Uruguay Ramón Méndez, who was present in Paris in 2015, said it was an extraordinarily strong shock to hear of Trump rolling back the Clean Power Plan. He said of all the policies the president has pursued, this one holds the worst consequences for the rest of the world. He also told The Guardian if the U.S. leaves the Paris agreement, “it will make it harder for other countries to maintain their ambitions.” Trump advisers reportedly can’t decide if pulling out of the agreement would be worth the diplomatic fallout sure to follow. But United Nations environment chief Erik Solheim pointed to an economic fallout as well. He told Reuters , “The future is green. Obviously if you are not a party to the Paris agreement, you will lose out. And the main losers of course will be the people of the United States itself because all the interesting, fascinating new green jobs would go to China and to the other parts of the world that are investing heavily in this.” Even if Trump doesn’t back out of the agreement, he still needs to take action. Peking University expert Zhang Haibin told The Guardian the president could pursue a semi-withdrawal instead: “I think the greater likelihood is that Trump will end up not pulling out of the pact but instead adopting a passive approach towards it [and] meeting none of its commitments.” Via The Guardian Images via Wikimedia Commons and Michael Vadon on Flickr

Massive iceberg draws tourists to tiny Canadian town

Comments Off on Massive iceberg draws tourists to tiny Canadian town

A new natural attraction drew scores of tourists to a small town of around 500 people in Newfoundland, Canada over Easter weekend. A massive iceberg appeared near the coast, and photographers dashed to the area to snap pictures. The Southern shore highway close to Ferryland filled with traffic over the weekend as tourists came to view the impressive iceberg. The Newfoundland coast area is commonly called iceberg alley due to the ice blocks that float down during the spring from the Arctic , but this particular huge iceberg might stay right where it is, according to Ferryland Mayor Adrian Kavanagh, who told The Canadian Press it’s the biggest one he’s ever seen in the area. Related: Naturally striped Antarctic icebergs are almost too beautiful to be real Usually just the tip of an iceberg is visible, with the rest of the mass beneath the waves, so many run aground when they float near the coast. Local Don Costello told CBC News the iceberg probably won’t be moving unless winds keep blowing because it’s stuck on shallow ground. He estimated the iceberg’s highest point is roughly 150 feet. The BBC reported more icebergs are drifting through iceberg alley than is normal for this point in the year, with hundreds of icebergs in the Atlantic. This particular iceberg has moved around some and broken apart, but it appears it’ll stick around for a while. That’s good for tourism – a tour operator told CBC News they’re happy when the icebergs are grounded, and his company is receiving dozens of online bookings every day. Iceberg tourism season technically hasn’t even started – there are a few weeks to go. Costello told CBC News, “I met a couple of people and they were looking for somewhere to get a bowl of soup or a sandwich or something, and there’s only two places here…and they don’t open until the 24th of May.” Via the BBC and CBC News Images via Randy Wheeler on Facebook , Fantasy RV Tours on Facebook , and Alison Thorne on Facebook
