For anyone who used to play with slot cars as a child, Sweden's new electrified road might bring back some memories.In the first of its kind, the Scandinavian country is trialling the world's first public road which allows electric vehicles to recharge while driving. Similar to a slot-car track, vehicles are able to connect to an electric rail that's embedded into the road.Sweden has a goal of achieving a completely fossil fuel free vehicle fleet by 2030, so this electrified road is part of several projects the Swedish Transport Administration has created to develop and test technologies that may be able to help the country reach its target.In this particular project, 'eRoadArlanda', electricity is transferred via a movable arm that attaches to the tracks built into the middle of the road. While the system is designed with the capacity to feed heavier vehicles such as trucks, it's also developed to work for cars and buses.When vehicles approach the track, a sensor from the car or truck detects the electrified rail and the movable arm lowers from underneath the vehicle and inserts into the rail. The arm has been designed to be flexible, providing the car, or truck, the freedom to move around the road without disconnecting."One of the most important issues of our time is the question of how to make fossil-free road transportation a reality," Hans S?ll, chairman of the eRoadArlanda says."We now have a solution that will make this possible, which is amazing. Sweden is at the cutting edge of this technology, which we now hope to introduce in other areas of the country and the world."The track stretches along two kilometers (1.2 miles) and has been installed on public road "893" just 30 minutes outside of Stockholm.The eRoad has many advantages, S?ll says. If implemented it will mean electric vehicle batteries can be smaller -- and therefore lighter -- because they won't need to retain as much charge, the vehicles will then be cheaper to manufacture and will ultimately be more sustainable.For a heavy truck to be 100% electric, he explains, it would need a battery that weighs 40 tonnes. But if technology like the eRoad was readily available, the truck's battery would be able to weigh as little as 600 kilograms.It would also fix a wider issue that many electric vehicle owners face: The worry and inconvenience of keeping vehicles charged."Today you're not 100% sure how far you can go with your battery but if you have a combination of electric roads you will feel a little bit more confident that you'll get where you want to go," S?ll says.The technology is also safe and adverse weather such as rain, snow and ice should not cause any major issues thanks to draining and usual maintenance. The electricity also isn't a risk to humans or animals."There's no electricity at the surface and the rail is only electrified if an actual authorized vehicle is passing, so if you don't have an electric vehicle that's authorized to use the electricity, the electricity will not be turned on at all -- it will not be on 24/7."There will also be plenty of signage around the area indicating the road is electrified and the system is equipped with safety circuits.S?ll says while the new project cost €6.4 million (.7 million) to develop, if it were more widely implemented across the country it would eventually work out less than €1 million (.2 million) per kilometer to build.That is, if the government decides to implement it nationally."The Government wants to test one or two additional technologies ... that will then be evaluated in two years or so, (and) after that they will pick out one of those technologies (that have been tested) to build a longer pilot stretch that will be between 20 and 40 kilometers," he says.For now, the eRoad will be used and trialled for two years by a truck carrying freight in order to determine how well the innovation works under various weather conditions and in conjunction with normal road traffic.The-CNN-Wire 3992

FedEx said Monday they are planning to hire 70,000 seasonal workers as they head into the holidays.In a hiring statement on its website, the shipping company said most of those hired for its "peak season" would be added to its FedEx Ground network."As our team of more than 500,000 team members is busy preparing to deliver the holidays, we once again expect to see a large number of packages traverse our global network over the 2020 peak holiday shipping season," FedEx said. "In order to provide the best possible service during this busy time of the year, FedEx is increasing hours for some existing employees and boosting our workforce with seasonal positions, as needed." The Memphis-based company added that it expanded FedEx Ground¡¯s year-round Sunday residential coverage to nearly 95% of the U.S. population, which went into effect Sunday. 857

For the most part, we've already been sheltering in our homes as we all try to get a grip on the pandemic. And this holiday season, which started Thursday with the first day of Hanukkah, families are looking for ways to make it special.Rabbi Robert Nosanchuk says his team is helping families celebrate Hanukkah safely at home through live stream services online.¡°Many participants will light candles together on Zoom. So, we'll literally light up the internet,¡± Nosanchuk said.And while you may not be able to give gifts in person this year, you can still offer the traditional monetary Hanukkah gift virtually.But this year, Nosanchuk is asking families to focus ways to build a more peaceful and just society.¡°Whatever faith you may be representing, I hope you'll know that your Jewish neighbors are holding their Hanukkah menorah by the window to publicize that miracles do happen,¡± Nosanchuk said. ¡°I pray strongly that we'll all be healed. We'll feel well in the new year.¡±This story was originally published by Taneisha Cordell at WEWS. 1051

For the past two years, 52-year-old Kendra Jackson of Omaha, Nebraska just thought she had a bad cold."When it first started out, I just thought it was my allergies or a runny nose -- like the beginning of a fresh cold," Jackson said.The coughing, sneezing and runny nose began 2? years after Jackson was involved in a serious car accident. She remembers hitting her face against the dashboard, and she has struggled with migraine headaches ever since.In 2015, Jackson's "runny nose" began to worsen."When it didn't go away, I kept going back and forth to the doctors, and they prescribed every kind of medicine you can think of, and my nose just kept on running," she said.The doctors she saw told her that she probably had allergies. But this year, Jackson went to physicians at the University of Nebraska Medical Center and learned the real reason behind her nasal discharge: a cerebrospinal fluid (or CSF) leak caused by a small hole in her skull."She would wake up in the morning after sleeping upright in a chair, and the whole front of her shirt was wet with fluid. It was a lot of fluid," said Dr. Christie Barnes, a rhinologist at the University of Nebraska Medical Center and a lead surgeon on the case.Jackson said she was losing about half a liter of fluid per day.A physician's assistant "astutely recognized right away that this was something different than a runny nose and was consistent with a CSF leak. So we had her collect her fluids and sent it off for evaluation," Barnes said.Cerebrospinal fluid is a clear, colorless fluid that surrounds and protects the brain and spinal cord. The fluid also helps to remove waste products from the brain and distribute nutrients and other substances throughout the central nervous system, according to the Cleveland Clinic."CSF is a fluid that actually bathes the brain. Because the skull is a fixed box and the brain is a nice soft organ, it needs to be protected from moving around inside that hard box," Barnes said. "So it actually provides a cushion for the brain and the spinal cord."Cerebrospinal fluid is produced continuously in the brain and is normally absorbed into the bloodstream through protrusions in the outer membrane of the brain, called the dura mater.But in Jackson's case, a tiny hole in her cribriform plate -- a thin bone that separates her cranial and nasal cavities -- allowed the fluid to drip into her nose and mouth, resulting in her symptoms.According to Barnes, this part of the skull is "very thin, less than a potato chip. And it's one of the most common locations for this type of a CSF leak," Barnes said.Cerebrospinal fluid leaks are relatively rare, occurring in approximately five in 100,000 individuals worldwide every year. They are most commonly caused by trauma or surgery, according to the CSF Leak Association.In Jackson's case, the physicians believe that her car accident may have caused a small hole that increased in size over time."She was rear-ended and had head trauma, so it's certainly possible," Barnes said. "It may have caused a bit of a thin area there. Her symptoms actually started a little bit after (the accident), so for her, I think there's probably a combination of both the trauma and the increased pressure."Depending on the amount of fluid loss, cerebrospinal fluid leaks can be life-threatening. They also place the patient at an increased risk of infections such as meningitis, according to Barnes.In order to treat Jackson's condition, physicians at the University of Nebraska Medical Center performed a surgery that plugged the hole in her skull using tissue from her nose and abdomen, Barnes said."I used tissue from the inside of her nose to plug the leak," Barnes said. "I also borrowed some abdominal fat; it makes a great plugging agent in this location, so with just a tiny bit of fat, I was able to plug the leak."Almost a month after the surgery, Jackson is back home and reports that the mysterious drip has disappeared."I don't have the nasal drip anymore, but I still have the headaches," she said. "I actually feel pretty good, and I'm able to get a little bit of sleep."Though her condition is rare, Jackson wants people to know that cerebrospinal fluid leaks can occur, particularly after head trauma: "For people who hear my story, if they're tasting a very salty taste and something's draining in the back of your throat, it's probably something other than allergies. So get to the doctor." 4474

For most Americans, wearing a mask in public has become part of the daily routine, and in most states, they¡¯re required in indoor spaces.Even though interactions in public settings might be brief, public health experts have recommended wearing masks outside of the household.But what about family gatherings? Should you wear a mask when visiting relatives? Should you even see relatives outside of your household during a pandemic?If you ask Dr. Christopher Murray, the director of the Institute for Health Metrics and Evaluation at the University of Washington, he is opting not to see extended relatives amid the pandemic. And looking forward to the holiday season, Murray does not plan on seeing extended relatives.¡°Personally, in our family, we will not have our family get together,¡± Murrays said about Thanksgiving. ¡°I am particularly cautious. That would be our strategy. Certainly, we have avoided, on a personal level, we have avoided any indoor exposure to friends or family and have restricted any exposure at all to outdoor interaction where we can maintain 6 feet or more.¡±On Thursday, Murray¡¯s organization released new projections that indicated that near universal wearing of face coverings outside of the home would save 67,000 American lives.¡°If you have a gathering of other family members that are not in your household, then yes, you should be wearing a mask or at least eating outdoors and distancing, which becomes very, very difficult in the winter, Murray said. As part of Murray¡¯s projections, an estimated 1,500 Americans will die per day from coronavirus-related illnesses in November with those numbers continuing to rise into the Thanksgiving holiday. But, those figures drops significantly if masks are worn outside of the home.Unlike Murray, Dr. Amesh A. Adalja, a senior scholar at the Johns Hopkins Center for Health Security, he takes a different approach around family. He said on the topic of wearing masks or avoiding interactions with extended family members, it depends on a person¡¯s risk tolerance.¡°I am very risk tolerant,¡± Adalja said. ¡°I am an infectious disease physician. I have taken care of people with the coronavirus. Both of my parents are physicians. I don¡¯t take any special precautious with my parents. I don¡¯t think they take any special precautious with me.¡°I think physicians might be risk tolerant, but I have not changed my behaviors with people I see regularly, other than if they¡¯re telling me they have a fever, and then I might say ¡®stay away¡¯ because I don¡¯t want to be quarantined and not be able to work.¡±Adalja agrees with Murray, however, that the more people that are involved in gatherings, the higher the risk. He said there is no right or wrong answer when deciding on attending an event with family.¡°When you make decisions on attending things, you have to make a risk calculation based on the fact that this virus is in the community, and that it¡¯s likely to be at any activity with a sizeable number of people,¡± Adalja said.Adalja agrees, however, that there is a risk in attending family gatherings, and while face coverings are effective, they're not a panacea. While the CDC doesn¡¯t explicitly discourage family gatherings, the organization has issued guidance on family gatherings. The guidelines include holding events outside when possible, keep seating and people six feet apart, and mask wearing when six feet of stance is not possible. The guidance even goes so far to recommend encouraging guests to bring their own silverware. 3521
