Comments Off on Elon Musk’s first tunnel is almost complete and he’s offering free rides

Another day, another genius marketing idea from Elon Musk . In an Instagram post , Musk announced that he plans to offer free rides in The Boring Company’s first tunnel — which he described as “almost done.” Musk went on to say: “As mentioned in prior posts, once fully operational (demo system rides will be free), the system will always give priority to pods for pedestrians and cyclists for less than the cost of a bus ticket.” First Boring Company tunnel under LA almost done! Pending final regulatory approvals, we will be offering free rides to the public in a few months. Super huge thanks to everyone that helped with this project. Strong support from public, elected officials & regulators is critical to success. As mentioned in prior posts, once fully operational (demo system rides will be free), the system will always give priority to pods for pedestrians & cyclists for less than the cost of a bus ticket. A post shared by Elon Musk (@elonmusk) on May 10, 2018 at 6:49pm PDT The Boring Company will offer rides in the tunnel under the Los Angeles , California area “pending final regulatory approvals” in a few months. Elon Musk thanked people who have been involved in the project, and said “Strong support from public, elected officials and regulators is critical to success.” As he often does, Musk answered a few questions about the project on Twitter. He said the company has already started working on a route between New York and Washington, D.C., and that they hope to start work on a route between Los Angeles and San Francisco in 2019. Musk explained that one would be a true Hyperloop with “pressurized pods in near vacuum tunnels,” and that passengers on that route would be able to travel faster than if they were on a jetliner. Related: Boring Company confirms plans to use excavated dirt for low-cost housing bricks When one Twitter user requested a stop near Vandenburg, an Air Force base in Santa Barbara County from which SpaceX launches rockets, Musk responded , “A cool thing about the design is that’s easy to incorporate branch loops to serve small to mid-size cities without slowing down the main loop at all.” The Boring Company’s frequently asked questions page says the initial test tunnel is in Hawthorne, California. According to the Los Angeles Times , in April the City Council’s public works committee unanimously approved an environmental review exemption for a 2.7-mile tunnel.

Comments Off on New research links LED streetlights to increased risk of cancer

Researchers at the University of Exeter and the Barcelona Institute for Global Health have concluded that there is a “strong link” between exposure to LED lighting and increased risk of breast and prostate cancer . The “blue light” emitted by LED lights seems to affect circadian rhythms and sleeping patterns, which then impacts hormone levels. “Humans have evolved to need light during the day and darkness at night,” researcher Alejandro Sánchez de Miguel told The Telegraph . “As towns and cities replace older lighting, we’re all exposed to higher levels of ‘blue’ lights, which can disrupt our biological clocks.” Previous research has documented the carcinogenic risk of night-shift work and artificial light . “We know that depending on its intensity and wave length, artificial light, particularly in the blue spectrum, can decrease melatonin production and secretion,” study co-author Martin Aubé explained to EurekAlert . In addition to regulating sleep cycles, melatonin functions as an anti-inflammatory antioxidant. Blue light, which is also emitted from tablet, phone , computer, and TV screens, is one of the shortest-wavelength, highest-energy forms of light. Related: A glowing glass “lantern” turns this energy-efficient office into a beacon This research comes as many cities are making the switch to LED streetlights, which are more energy-efficient and cheaper than traditional lighting. Published in the journal Environmental Health Perspectives , the study included more than 4,000 people in 11 distinct regions of Spain in its analysis. It also incorporated images taken aboard the International Space Station to gain a fuller sense of blue light’s impact on a global scale. Public Health England has recommended further study of the impact of LED lighting before it is more widely adopted, while the American Medical Association has recommended that municipalities and businesses install the lowest-intensity LED lighting, with shading to provide additional protection. + Environmental Health Perspectives Via The Telegraph Images via Depositphotos (1)

World’s first electric road that charges moving vehicles debuts in Sweden

Comments Off on World’s first electric road that charges moving vehicles debuts in Sweden

The first electrified road capable of charging EVs as they drive across it is now open outside of Stockholm , Sweden. While the road — which links Stockholm Arlanda airport to a nearby logistics site — is only two kilometers long, it is a significant step forward in Sweden’s strategic plan for energy and climate change . The country aims to become independent of fossil fuels by 2030 – a task that will require a 70 percent reduction in emissions from the transportation sector. Once expanded, the electric roadways and highways in Sweden will make it convenient to charge electric vehicles and ease the country’s transition from traditional combustion engine vehicles. The system works by transferring electricity from the installed underground rail to the vehicle above through a flexible arm that attaches to the charging vehicle . “There is no electricity on the surface,” Hans Säll, chief executive of  eRoadArlanda , explained to the Guardian . “There are two tracks, just like an outlet in the wall. Five or six centimeters down is where the electricity is. But if you flood the road with salt water , then we have found that the electricity level at the surface is just one volt. You could walk on it barefoot.” Related: Siemens debuts first electrified eHighway in the US It currently costs 1 million euros to construct one kilometer of electrified road, but this is still 50 times less than the cost of installing an equivalent distance of an overhead tram line. At the moment, Sweden maintains about half a million kilometers of roadways, of which 20,000 are highways. “If we electrify 20,000 kilometers of highways that will definitely be enough,” Säll said. “The distance between two highways is never more than 45 kilometers, and electric cars can already travel that distance without needing to be recharged. Some believe it would be enough to electrify 5,000 kilometers.” Sweden and Germany are in discussion to eventually construct a network of electrified roads to encourage a Europe-wide adoption of electric vehicles.

The Gulf Stream is the weakest it’s been in 1,600 years – here’s why that’s really bad news

Comments Off on The Gulf Stream is the weakest it’s been in 1,600 years – here’s why that’s really bad news

The Gulf Stream current, which serves as an important regulator of weather and climate along the Atlantic Ocean, is now the weakest it has been in at least 1,600 years. This dramatic slowing of the current, known as the Atlantic Meridional Overturning Circulation (Amoc), could usher in extreme shifts in weather patterns, such as more brutal European winters, rapid sea level rise on the American East Coast , and the disruption of essential tropical rainstorms. Suddenly, the 2004 climate-change disaster film The Day After Tomorrow, which depicted the dramatized consequences of a Gulf Stream slowdown, seems less science fiction, more predictive of a future plagued by catastrophic climate change. Although scientists have been aware of Amoc’s slowdown since 2004, two recent studies paint a more complete picture of just how dramatic this weakening has been. “The [current] climate models don’t predict [an Amoc shutdown] is going to happen in the future,” Dr. David Thornalley, leader of one of these recent studies published in the journal Nature , told the Guardian . “The problem is how certain are we it is not going to happen? It is one of these tipping points that is relatively low probability, but high impact.” Thornalley’s team gathered and analyzed sediments from North Carolina ‘s Cape Hatteras, as well as shells of marine animals at various Atlantic sites, to determine the full impact of the current slowdown. The study concludes that climate change has played at least a significant role in the weakened Amoc. Related: The Great Pacific Garbage Patch is growing at an exponential rate Also published in Nature , the second study used thermometer data from the past 120 years to reach a similar conclusion: Amoc is about 15 percent weaker than it was in 400 AD. While the second study places much of the blame on climate change , the first study also cites natural climate variability as a contributing factor to Amoc’s slowdown. Regardless of its causes, the weakening is recognized in both studies as a potentially destabilizing phenomenon. “If we do not rapidly stop global warming, we must expect a further long-term slowdown of the Atlantic overturning,” second study co-author Alexander Robinson told the Guardian . “We are only beginning to understand the consequences of this unprecedented process – but they might be disruptive.” Via The Guardian Images via Depositphotos (1 , 2)

The Keystone Pipeline leak was nearly twice as big as we thought

Comments Off on The Keystone Pipeline leak was nearly twice as big as we thought

New reports show that nearly twice as much crude oil leaked from the Keystone Pipeline in South Dakota last November than originally estimated. TransCanada spokesperson Robynn Tysver said that roughly 9,700 barrels of oil leaked instead of the estimated 5,000 barrels. This new information means the leak is among the biggest onshore spills in the United States since 2010. There are 42 gallons in one barrel of oil, so instead of 210,000 gallons as was originally estimated, around 407,700 gallons leaked in what TransCanada refers to as the Amherst incident . This means the spill was the “seventh largest onshore oil or petroleum product spills” reported to the United States Department of Transportation since 2010, according to Aberdeen American News. Related: Keystone 1 oil pipeline leaks 210,000 gallons days ahead of Keystone XL permit decision TransCanada started utilizing the pipeline again 12 days following the leak. Tysver told American News, “The remediation work on the property has been completed. We have replaced the last of the topsoil and have seeded the impacted area.” The Amherst incident cost the company around $9.57 million, according to the news publication, citing an updated pipeline safety administration report. TransCanada said on their website they sampled groundwater at 12 monitoring wells and there “was no impact to groundwater.” The Keystone Pipeline connects oil fields in Alberta, Canada to refineries in the United States; Reuters described it as a 590,000 barrel-per-day pipeline. Aberdeen American News said according to a preliminary report, the pipe may have been damaged in 2008, during construction. Reuters said they had reviewed documents revealing Keystone has leaked far more oil, and more frequently, “than the company indicated to regulators in risk assessments” before operations started in 2010. The Pipeline and Hazardous Materials Safety Administration , part of the Department of Transportation, could release the final report on the leak in the upcoming few weeks.

Antibiotic-resistant "nightmare" bacteria are spreading across the US

Comments Off on Antibiotic-resistant "nightmare" bacteria are spreading across the US

A new breed of “nightmare” bacteria resists pretty much all of our antibiotics – and it’s rapidly spreading across the US. The bacteria – called carbapenem-resistant Enterobacteriaceae (CRE) – is different from your run-of-the-mill antibiotic-resistant bacteria because it is incredibly deadly, with 50 percent of infected patients dying. Not only that, but it is spreading like “wildfire” with over 200 cases identified in 27 states. Researchers at the CDC said that last year they tested  5,700 samples of resistant bacteria, and of those samples, 221 were CRE or similar bacteria. That’s a full 15 percent. “I was surprised by the numbers” of bacteria with unusual antibiotic resistance, Dr. Anne Schuchat, principal deputy director of the CDC, said. “This was more than I was expecting.” Once researchers detected these bacteria, they tested other patients in the same facility to see if the bacteria had spread. It turned out that 1 in 10 people had what scientists call a “silent” infection, where they have the bacteria in their bodies but aren’t showing symptoms. Related: Flesh-eating bacteria might be spread by mosquitoes in Australia Fortunately, doctors have a plan. They are working hard to stop the spread before it becomes common. To that end, the CDC created the Antibiotic Resistance Laboratory Network (ARLN) to test and track for these dangerous bacteria. Using an aggressive containment strategy, researchers have been able to control the infection. But the danger isn’t over – doctors and scientists will have to be vigilant to stay ahead of the antibiotic-resistance trend as bacteria continue to evolve and change to evade our efforts.

Comments Off on AeroMobil reveals flying taxi that transforms from car to electric airplane

Designed for both the skies and the streets, the AeroMobil 5.0 is the latest futuristic creation from the Slovakia-based flying car company. Rather than taking off as a traditional airplane does, the AeroMobil 5.0 is able to gain altitude through vertical thrust from powerful rotors embedded in retractable wings that deploy when you are ready to hit the skies. A rear propeller provides the vehicle with midair thrust. Billed as the “first and only electric VTOL (Vertical Takeoff and Landing vehicle) to also drive on the road,” the AeroMobil 5.0 could potentially someday be your taxi, offering convenient flights right at your doorstep. The AeroMobil 5.0 is designed to complement previous models of flying car from the company, including the AeroMobil 4.0. “The multi-product strategy means we can provide urban travel with the AeroMobil 5.0 VTOL and intra-city travel with the AeroMobil 4.0 STOL,” said Juraj Vaculik, co-founder and CEO of AeroMobil, in a statement . “Our strategy solves the limitations of alternative VTOL concepts which are tied to dedicated landing pods rather than also using the existing road infrastructure .” Related: Uber and NASA team up to launch flying taxis by 2020 The AeroMobil 5.0 is designed to seat four passengers, with each rider having access to a personalized experience thanks to a sophisticated advanced data, communications and media system onboard. The cumulative experience at AeroMobil and developed technologies upon which the new flying car is based has made the company quite confident in its ability to finally deliver on that long-held dream of owning, or at least riding in, a flying car. “AeroMobil 4.0 STOL uses several patented technologies, a highly innovative combustion engine and has the benefit of using existing aerospace and automotive technology, combined in a unique way, thus achieving far greater energy efficiency , speed and range than any electric VTOL,” said AeroMobil Chairman Patrick Hessel in a statement . “It is also designed within existing regulation , hence enabling much sooner go-to-market in 2020 than the electric VTOL category, which in general is being mooted as ready for shipment in 2025”.

Comments Off on "Have to have see-through," says Trump of border wall

President Donald Trump stopped in Otay Mesa during his trip to California to inspect eight prototypes of the potential border wall . His feedback? “You have to have see-through,” Trump told reporters, according to CBS Los Angeles . “You have to know what’s on the other side of the wall. You could be two feet away from a criminal cartel and you don’t even know they’re there.” If we don’t have a wall system, we’re not going to have a country. Congress must fund the BORDER WALL & prohibit grants to sanctuary jurisdictions that threaten the security of our country & the people of our country. We must enforce our laws & protect our people! #BuildTheWall pic.twitter.com/NGqNueukvj — Donald J. Trump (@realDonaldTrump) March 13, 2018 Trump examined 30-foot border wall prototypes during his first trip to California since he won the election. The San Diego Union-Tribune reported he preferred a combination of a see-through wall topped with steel or rounded concrete to make it harder for climbers to scale. Archinect said there were solid, opaque options as well as four other materials, non-concrete prototypes Trump appeared to favor. Related: Artists are turning the U.S.-Mexico border fence into the world’s longest peace-themed mural The president said, “If you don’t have a wall system, we’re not going to have a country. There’s a lot of problems in Mexico , they have the cartels. We’re fighting the cartels, we’re fighting them hard.” Trump also addressed criticism about the border wall from California’s governor, Jerry Brown , saying he thinks the governor “has done a very poor job running California” and “the place is totally out of control.” “You have sanctuary cities where you have criminals living in the sanctuary cities,” he said. Brown responded on Twitter , saying bridges are better than walls. ? Thanks for the shout-out, @realDonaldTrump . But bridges are still better than walls. And California remains the 6th largest economy in the world and the most prosperous state in America. #Facts — Jerry Brown (@JerryBrownGov) March 13, 2018 The San Diego Union-Tribune said hordes of both supporters and critics gathered throughout San Diego, and people were largely peaceful, but for shouting insults at the other side, and a Mexican flag was torn and almost burned.
