Venezuela's Water System is Collapsing (nytimes.com) 229

In Venezuela, a crumbling economy and the collapse of even basic state infrastructure means water comes irregularly -- and drinking it is an increasingly risky gamble. Venezuela's current rate of infant mortality from diarrhea, which is closely related to water quality, is six times higher than 15 years ago, according to the World Health Organization. From a report: But the government stopped releasing official public health data years ago. So The New York Times commissioned researchers from the Universidad Central de Venezuela to recreate the water quality study they had conducted regularly for the water utility in Caracas from 1992 until 1999. The scientists found that about a million residents were exposed to contaminated supplies. This puts them at risk of contracting waterborne viruses that could sicken them and threatens the lives of children and the most vulnerable. "This is a potential epidemic," said Jose MarÃa De Viana, who headed Caracas's water utility, Hidrocapital, until 1999. "It's very serious. It's unacceptable."

In the latest study, 40 samples were taken from the capital's main water systems and tested for bacteria and for chlorine, which keeps water safe. The study also tested alternative water sources used by city residents during supply outages. One third of the samples did not meet national norms. This should have required Hidrocapital to issue a sanitation alert, according to the utility's own internal regulations. But Venezuela's government has not issued any alerts at least since President Nicolas Maduro's Socialist Party took power 20 years ago. "The biggest health risk that we see there right now is water -- water and sanitation," the head of the International Federation of the Red Cross, Francesco Rocca, told foreign reporters this week, referring to Venezuela.

The Death of Cars Was Greatly Exaggerated (wired.com) 153

Personal car ownership in the US has increased in the past 10 years, even in the frenzied urban places where Uber and car-share have become verbs. From a report: According to research from former New York City transportation official Bruce Schaller, the number of vehicles has grown faster than the population in some of the cities where ride-hail is most popular: Boston, Los Angeles, New York, Philadelphia, and Chicago. Moreover, some services targeted to the aspirationally or actually car-free have hit the skids. Car2Go, the car-sharing company now jointly owned by Daimler and BMW, said earlier this month it would pull out of half of the North American cities where it operates. (The company, which allows users to pick up and drop off cars at regular street parking spaces, says it will focus its firepower on its remaining North American cities: New York, Montreal, Seattle, Vancouver, and Washington.) BMW-owned ReachNow, a wide-ranging experiment in ride hailing and car rental, folded in the US this summer. The scooter-share folks at Lime last month killed their experimental LimePod car-share service in Seattle. General Motors wound down its Maven car-sharing service in eight of its 17 North American cities this summer. Uber and Lyft, now public companies, are losing gobs of money, and the services' most popular times are Friday evenings, which seems to indicate less that people are ditching their personal cars than ditching their personal cars while drinking.

EPA Rolls Back Obama-Era Regulations On Clean Water (wsj.com) 206

An anonymous reader quotes a report from The Wall Street Journal: President Trump's administration has rescinded an Obama-era policy that expanded federal oversight and the threat of steep fines for polluting the country's smaller waterways (Warning: source paywalled; alternative source), furthering his deregulatory efforts in the 14 months that remain before the next election. Environmental Protection Agency Administrator Andrew Wheeler on Thursday signed a final rule that limits the scope of federal clean-water regulations in an effort to clear up confusion for landowners whose property sits near water sources that feed into the country's network of major rivers. The Obama administration in 2015 had expanded federal oversight upstream, it said, to better protect wildlife and the country's drinking-water supply from industrial runoff and pollution.

Mr. Wheeler called that expansion an overreach, saying it grew to cover dry land in some cases. Farmers, property developers, chemical manufacturers and oil-and-gas producers -- some of whom are key voter groups for the 2020 election -- have voiced opposition to it, with many saying it overreached by intruding on property owners' rights. Court battles following the Obama-era rule have led to fractured rules across the country. Amid the legal challenges, the regulation is in place only in 22 states, though the Trump administration's decision could spark its own series of court fights.
Thursday's rule "restores regulatory text that existed before the 2015," the report notes. "Property that is no longer covered by the 1972 Clean Water Act remains protected by state rules. Major waterways, such as most rivers and lakes, were already under protection of the Clean Water Act and still will be after the rollback."

Drinking More Than 2 Sodas Per Day Can Increase Your Risk of Dying, Study Finds (abc4.com) 118

According to a new study, those who drink more than two glasses of soda or any soft drink per day have a high risk of dying. From a report: Experts studied more than 450,000 people from 10 European countries for up to 19 years and found that those who had more than two glasses of soda per day had a higher risk of dying than people who drank less than one glass per month. The study, published Tuesday in the journal JAMA Internal Medicine, stated that men or women who drank two or more glasses a day of sugar-sweetened soft drinks had a higher risk of dying from digestive disorders, while those who drank the same amount of diet drinks had higher risks of dying from cardiovascular disease. The findings note that none of the subjects had cancer, diabetes, heart disease or stroke prior to the study.

22 Million Pounds of Plastics Enter the Great Lakes Each Year (chicagotribune.com) 98

An anonymous reader quotes a report from Chicago Tribune: Plastic debris makes up about 80% of the litter on Great Lakes shorelines. Nearly 22 million pounds enter the Great Lakes each year -- more than half of which pours into Lake Michigan, according to estimates calculated by the Rochester Institute of Technology. Regardless of size, as plastics linger in the water, they continue to break down from exposure to sunlight and abrasive waves. Microplastics have been observed in the guts of many Lake Michigan fish, in drinking water and even in beer. Perhaps the most worrisome aspect is that the impact of microplastics on human health remains unclear. Plastics are known to attract industrial contaminants already in the water, like PCBs, while expelling their own chemical additives intended to make them durable, including flame retardants.

While there are still more questions than answers about potential health consequences, one thing is clear: Southern Lake Michigan is a hot spot for plastics. Once plastics enter the lake, they follow lake currents, potentially migrating to other states but largely remaining trapped at the southern end. What goes into Lake Michigan typically stays there. While water from the other Great Lakes moves downstream, Lake Michigan's only major outflow is the Chicago River (and the water it intermittently exchanges with Lake Huron at the Straits of Mackinac). As a result, a drop of water that enters Lake Michigan stays for about 62 years, according to the National Oceanic and Atmospheric Administration.
A study published last year found that around 85% of fish caught from three major Lake Michigan tributaries -- the Milwaukee, St. Joseph and Muskegon rivers -- had microplastics in their digestive tracts.

"In the sample size of 74 fish representing 11 species, the invasive round goby had the highest concentrations, possibly from eating filter-feeding quagga mussels, which scientists suspect may be accumulating microplastics," the Chicago Tribune reports. "While detecting microplastics in the guts of Lake Michigan fish is significant, scientists are now studying if these pollutants build up or are excreted by the fish."

Crystalline Nets Harvest Water From Desert Air, Turn CO2 Into Liquid Fuel (sciencemag.org) 151

Omar Yaghi, a chemist at the University of California, Berkeley, reported that he and his colleagues have created a solar-powered device that uses porous crystalline material, known as a metal-organic framework (MOF), to suck water vapor and carbon dioxide (CO2) out of the air and then release it as liquid water. Science Magazine reports: One recent market report predicted that sales of MOFs for applications including storing and detecting gases will balloon to $410 million annually over the next 5 years, up from $70 million this year. "Ten years ago, MOFs showed promise for a lot of applications," says Omar Farha, a MOF chemist at Northwestern University in Evanston, Illinois. "Now, that promise has become a reality." One application is Yaghi's, which he hopes will help provide drinking water for the estimated one-third of the world's population living in water-stressed regions. Yaghi and his colleagues first developed a zirconium-based MOF in 2014 that could harvest and release water. But at $160 per kilogram, zirconium is too expensive for bulk use. So, last year, his team came up with an alternative called MOF-303, based on aluminum, which costs just $3 per kilogram. In the desert of Arizona, Yaghi and his team placed their MOF in a small, clear plastic container. They kept it open to the air at night, allowing the MOF to absorb water vapor. They then closed the container and exposed the MOF to sunlight, which drove liquid water from it -- but the harvest was only about 0.2 liters per kilogram of MOF per day.

At last week's meeting of the American Chemical Society and in the 27 August issue of ACS Central Science, Yaghi reported that his team has devised a new and far more productive water harvester. By exploiting MOF-303's ability to fill and empty its pores in just minutes, the team can make the new device complete dozens of cycles daily. Supported by a solar panel to power a fan and heater, which speed the cycles, the device produces up to 1.3 liters of water per kilogram of MOF per day from desert air. Yaghi expects further improvements to boost that number to 8 to 10 liters per day. Last year, he formed a company called Water Harvesting that this fall plans to release a microwave-size device able to provide up to 8 liters per day. The company promises a scaled-up version next year that will produce 22,500 liters per day, enough to supply a small village. "We're making water mobile," Yaghi says. "It's like taking a wired phone and making a wireless phone."

Soft Drinks, Including Sugar-Free, Linked To Increased Risk of Early Death 229

An anonymous reader quotes a report from The Guardian: People who regularly consume soft drinks have a higher risk of an early death, researchers have found, with the trend seen for both sugared and artificially sweetened drinks. While experts say the study cannot prove soft drinks are a driver of an increased risk of death, they say the work -- which is the largest study of its kind -- supports recent public health efforts to reduce consumption of soft drinks, such as the UK's sugar tax. Writing in the journal Jama Internal Medicine, Dr Neil Murphy, a co-author of the research from the International Agency for Research on Cancer, and colleagues report how they analyzed data from more than 450,000 people, 70% of whom were women, across 10 European countries including the UK. Participants had an average age of just over 50, and those with health conditions such as cancer, heart disease or diabetes at the outset were not included in the analysis. Individuals joined the study between 1992 and 2000 and were then followed up for an average of 16 years, during which time more than 41,600 deaths were recorded.

When participants signed up they were asked a number of questions about aspects of their lifestyle such as exercise, smoking and weight as well as diet and nutrition -- including their average consumption of drinks such as fizzy drinks, fruit squash and energy drinks. Fruit juice consumption was not included. The results show 9.3% of those who drank less than one glass of soft drink a month died during the study, compared with 11.5% of those who drank two or more 250ml glasses a day. The team say that once factors such as body mass index, diet, physical activity, smoking and education were taken into account, that translates to a 17% higher risk of death among those consuming two glasses a day compared with those drinking less than one glass a month.

Strange Forest 'Superorganism' Is Keeping a New Zealand Vampire Tree Alive (livescience.com) 77

The Grim Reefer shares a report from Live Science: Once a mighty kauri tree -- a species of conifer that can grow up to 165 feet (50 meters) tall -- the low, leafless stump looks like it should be long dead. But, as a new study published today in the journal iScience reminds us, looks are only surface-deep. Below the soil, the study authors wrote, the stump is part of a forest "superorganism" -- a network of intertwined roots sharing resources across a community that could include dozens or hundreds of trees. By grafting its roots onto its neighbors' roots, the kauri stump feeds at night on water and nutrients that other trees have collected during the day, staying alive thanks to their hard work.

Using several sensors to measure the movement of water and sap (which contains important nutrients) through the three trees, the team saw a curious pattern: the stump and its neighbors seemed to be drinking up water at exact opposite times. During the day, when the vibrant neighbor trees were busy transporting water up their roots and into their leaves, the stump sat dormant. At night, when the neighbors settled down, the stump circulated water through what was left of its body. The trees, it seemed, were taking turns -- serving as separate pumps in a single hydraulic network. So, why add a near-dead tree to your underground nutrient highway? While the stump no longer has any leaves, researchers wrote, it's possible that its roots still have value as a bridge to other vibrant, photosynthesizing trees elsewhere in the forest. It's also possible that the stump joined roots with its neighbors a long time ago, before it was, well, a stump. Since nutrients still flow through the stump's roots and into the rest of the network, the neighboring trees may never have noticed its loss of greenery.

Up To 25 Cups of Coffee a Day Still Safe For Heart Health, New Study Says (cnn.com) 140

Coffee lovers might be able to breathe a sigh of relief -- a new study found that drinking even large amounts of the caffeinated beverage won't stiffen arteries and harm your heart. From a report: Aficionados have been getting mixed messages about their favorite drink, with some research suggesting that drinking coffee can improve health while other studies advise people to cut down on their consumption. Previous studies suggested that coffee can cause a stiffening of the arteries, putting pressure on the heart and increasing the likelihood of stroke or heart attack. But a new study, funded in part by the British Heart Foundation, found that drinking five cups of coffee a day was no worse for the arteries than drinking less than one cup. The study of more than 8,000 people across the United Kingdom also found that even those who drank up to 25 cups a day were no more likely to experience stiffening of the arteries than someone drinking less than a cup a day.

Japan Prepares To Ban Flying Unmanned Aerial Vehicles Under the Influence of Alcohol (scmp.com) 48

Drinking and droning? It could soon cost you up to a year in jail in Japan, where an amendment to the country's civil aeronautics law being debated in the Diet would make it illegal to operate unmanned aerial vehicles while under the influence of alcohol. From a report: According to the transport ministry, there were 79 incidents involving drones in the last financial year. None of them involved a drunk operator but tighter restrictions were nonetheless regarded as a necessary pre-emptive move. "There are lots of different types of accidents that are reported each year but the majority are relatively minor and involve, for example, a drone operating on a predetermined route making an accidental landing," a ministry official said, adding that there were 63 reports of accidents in 2017 and 55 the previous year.

"We have no records of someone causing an accident with a drone while drinking, but we do know that in the US about three years ago, a drunk person landed a drone in the grounds of the White House," the official said. "We obviously want to avoid that sort of situation, so these new laws are designed to stop something before it happens." Under the new rules, a drone operator will be legally required to carry out preflight checks of the vehicle and authorities will carry out on-the-spot inspections when an accident occurs.

Drinking Six or More Coffees a Day Can Be Detrimental To Your Health, New Study Reveals (unisa.edu.au) 147

While the pros and cons of drinking coffee have been debated for decades, new research from the University of South Australia reveals that drinking six or more coffees a day can be detrimental to your health, increasing your risk of heart disease by up to 22 percent. From a report: In Australia, one in six people are affected by cardiovascular disease. It is a major cause of death with one person dying from the disease every 12 minutes. According to the World Health Organization, cardiovascular disease is the leading cause of death, yet one of the most preventable. Investigating the association of long-term coffee consumption and cardiovascular disease, UniSA researchers Dr Ang Zhou and Professor Elina Hypponen of the Australian Centre for Precision Health say their research confirms the point at which excess caffeine can cause high blood pressure, a precursor to heart disease.

This is the first time an upper limit has been placed on safe coffee consumption and cardiovascular health. "Coffee is the most commonly consumed stimulant in the world -- it wakes us up, boosts our energy and helps us focus -- but people are always asking 'How much caffeine is too much?'," Prof Hypponen says. "Most people would agree that if you drink a lot of coffee, you might feel jittery, irritable or perhaps even nauseous -- that's because caffeine helps your body work faster and harder, but it is also likely to suggest that you may have reached your limit for the time being.

Report Finds Widespread Contamination at Nation's Coal Ash Sites (washingtonpost.com) 123

Nearly all 250 coal-fired plants in operation in the U.S. have leaked chemicals and contaminated the local groundwater supply with toxins [Editor's note: the link may be paywalled; you can check the alternative source, and original report (PDF)], according to a report released this week by environmental groups Environmental Integrity Project and Earthjustice. From a report: The report found that 91 percent of the nation's coal-fired power plants reported elevated levels of contaminants such as arsenic, lithium, chromium and other pollutants in nearby groundwater. In many cases, the levels of toxic contaminants that had leaked into groundwater were far higher than the thresholds set by the Environmental Protection Agency, the groups said.

The examples span the country. At a family ranch south of San Antonio, a dozen pollutants have leaked from a nearby coal ash dump, data showed. Groundwater at one Maryland landfill that contains ash from three coal plants was contaminated with eight pollutants. In Pennsylvania, levels of arsenic in the groundwater near a former coal plant were several hundred times the level the EPA considers safe for drinking. The voluminous data became publicly available for the first time last year because of a 2015 regulation that required disclosures by the overwhelming majority of coal plants.

American Cheese Surplus Reaches Record High 398

According to the U.S. Department of Agriculture, there's a 1.4 billion-pound cheese surplus. "The glut, which at 900,000 cubic yards is the largest in U.S. history, means that there is enough cheese sitting in cold storage to wrap around the U.S. Capitol," reports NPR. Americans managed to consume nearly 37 pounds per capita in 2017, but that wasn't enough to reduce the surplus. From the report: The stockpile started to build several years ago, in large part because the pace of milk production began to exceed the rates of consumption, says Andrew Novakovic, professor of agricultural economics at Cornell University. Over the past 10 years, milk production has increased by 13 percent because of high prices. But what dairy farmers failed to realize was that Americans are drinking less milk. According to data from the USDA, Americans drank just 149 pounds of milk per capita in 2017, down from 247 pounds in 1975.

Suppliers turn that extra milk into cheese because it is less perishable and stays fresh for longer periods. But Americans are turning their noses up at those processed cheese slices and string cheese -- varieties that are a main driver of the U.S. cheese market -- in favor of more refined options, Novakovic tells Here & Now's Jeremy Hobson. Despite this shift, sales of mozzarella cheese, the single largest type of cheese produced and consumed in the U.S., remain strong, he says. Novakovic also notes that imported cheeses tend to cost more, so when people choose those, they buy less cheese overall. The growing surplus of American-made cheese and milk means that prices are declining. The current average price of whole milk is $15.12 per 100 pounds, which is much lower than the price required for dairy farmers to break even.

Freshwater is Getting Saltier, Threatening People and Wildlife (scientificamerican.com) 164

Salts that de-ice roads, parking lots and sidewalks keep people safe in winter. But new research shows they are contributing to a sharp and widely rising problem across the U.S. From a report: At least a third of the rivers and streams in the country have gotten saltier in the past 25 years. And by 2100, more than half of them may contain at least 50 percent more salt than they used to. Increasing salinity will not just affect freshwater plants and animals but human lives as well -- notably, by affecting drinking water. Sujay Kaushal, a biogeochemist at the University of Maryland, College Park, recounts an experience he had when visiting relatives in New Jersey. When getting a drink from the tap, "I saw a white film on the glass." After trying to scrub it off, he found, "it turned out to be a thin layer of salt crusting the glass."

When Kaushal, who studies how salt invades freshwater sources, sampled the local water supply he found not just an elevated level of the sodium chloride, widely used in winter to de-ice outdoor surfaces, but plenty of other salts such as sodium bicarbonate and magnesium chloride. He also found similar concentrations of these chemicals in most rivers along the east coast, including the Potomac, which provides drinking water for Washington, D.C. Where did all of it come from? De-icing salts, Kaushal determined, are part of the problem, slowly corroding our infrastructure.

There Is No Link Between Insomnia and Early Death, Study Finds (bbc.com) 58

A new report published in the journal Science Direct says there is no link between insomnia and early death. The researchers reportedly "reviewed 17 studies, which covered close to 37 million people, to compile their results," the BBC notes. From the report: This new report goes against what the NHS says, which claims that as well as putting people at risk of obesity, heart disease and type 2 diabetes, that insomnia shortens life expectancy. The NHS recommends things like exercising to tire yourself out during the day and cutting down on caffeine. It also says smoking, eating too much or drinking alcohol late at night can stop you from sleeping well. Other recommendations include writing a list of things that are playing on your mind and trying to get to bed at a similar time every night. "There was no difference in the odds of mortality for those individuals with symptoms of insomnia when compared to those without symptoms," the study says. "This finding was echoed in the assessment of the rate of mortality in those with and without symptoms of insomnia using the outcomes of multivariate models, with the most complete adjustment for potential confounders, as reported by the individual studies included in this meta-analysis. Additional analyses revealed a tendency for an increased risk of mortality associated with hypnotic use."

Authors of Controversial 'Seattle Minimum Wage' Study Revise Their Conclusions (bloombergquint.com) 290

Seattle's increase in the minimum wage "brought benefits to many workers employed at the time, while leaving few employed workers worse off," reports the New York Times -- citing a new study by the same researchers who'd claimed last year that workers were hurt by the wage increase.

"The dire warnings about minimum-wage increases keep proving to be wrong," argues a Bloomberg columnist, in an article shared by gollum123: The authors behind an earlier study predicting a negative impact have all-but recanted their initial conclusions. However, the authors still seem perplexed about why they went awry in the first place.... The increase was an "economic death wish" that was going to tank the expansion and kill jobs, according to the sages at conservative think tanks... Despite their dire forecasts, not only were new restaurants not closing, they were in fact opening; employment in food services and drinking establishments has soared...

As we noted in 2017, the study's fatal flaw was that its analysis excluded large multistate businesses with more than one location. When thinking about the impact of raising minimum wages, one can't simply omit most of the biggest minimum-wage employers in the region, such as McDonald's and other fast-food chains, or Wal-Mart and other major retailers... There were two other glaring defects in the first study that are worth mentioning. The first is that its findings contradicted the vast majority research on minimum wages. As was demonstrated back in 1994 by economists Alan Krueger and David Card, modest, gradual wage increases have not been shown to reduce employment or hours worked in any significant way. Ignoring that body of research without a very good reason made the initial University of Washington study questionable at best. Second, there potentially is a problem with having a lead researcher -- economist Jacob Vigdor, whose affiliations among others include the right-leaning Manhattan Institute -- whose impartiality is open to question.
Long-time Slashdot reader Martin S. writes that "When the UK introduced the minimum wage we had the same doom and gloom scenarios," adding that "the reality was very different." He argues that increasing the minimum wage "increased productivity so business did not suffer, reduced government spending on benefits, and increased the the velocity of money improving the overall economy.

"It had no measurable effect on unemployment."

A Device That Can Pull Drinking Water From the Air Just Won the Latest XPrize (fastcompany.com) 359

Two years ago, XPrize, which creates challenges that pit the brightest minds against one another, announced that it would give any startup or company $1 million that can turn thin air into water. This month, it announced that the challenge has been concluded. From a report: A new device that sits inside a shipping container can use clean energy to almost instantly bring clean drinking water anywhere -- the rooftop of an apartment building in Nairobi, a disaster zone after a hurricane in Manila, a rural village in Zimbabwe -- by pulling water from the air. The design, from the Skysource/Skywater Alliance, just won $1.5 million in the Water Abundance XPrize. The competition, which launched in 2016, asked designers to build a device that could extract at least 2,000 liters of water a day from the atmosphere (enough for the daily needs of around 100 people), use clean energy, and cost no more than 2 cents a liter.

"We do a lot of first principles thinking at XPrize when we start designing these challenges," says Zenia Tata, who helped launch the prize and serves as chief impact officer of XPrize. Nearly 800 million people face water scarcity; other solutions, like desalination, are expensive. Freshwater is limited and exists in a closed system. But the atmosphere, the team realized, could be tapped as a resource. "At any given time, it holds 12 quadrillion gallons -- the number 12 with 19 zeros after it -- a very, very, big number," she says. The household needs for all 7 billion people on earth add up to only around 350 or 400 billion gallons. A handful of air-to-water devices already existed, but were fairly expensive to use. The new system, called WEDEW ("wood-to-energy deployed water") was created by combining two existing systems. One is a device called Skywater, a large box that mimics the way clouds are formed: It takes in warm air, which hits cold air and forms droplets of condensation that can be used as pure drinking water. The water is stored in a tank inside the shipping container, which can then be connected to a bottle refill station or a tap.

Rolls-Royce Wants To Fill the Seas With Self-Sailing Ships (wired.com) 127

An anonymous reader shares a report: "Helsinki VTS, thank you for permission to depart," the captain says over the radio. He checks with the Vessel Traffic Service to see if there's anything to be looking out for. Just one other big ship, but also lots of small boats, enjoying the calm water, which could be hazards. Not a problem for this captain -- he has a giant screen on the bridge, which overlays the environment around his vessel with an augmented reality view. He can navigate the Baltic Discoverer confidently out of Finland's Helsinki Port using the computer-enhanced vision of the world, with artificial intelligence spotting and labeling every other water user, the shore, and navigation markers.

This not-too-far-in-the-future vision comes from Rolls-Royce. (One iteration of it, anyway: The Rolls-Royce car company, the jet engine maker, and this marine-focused enterprise all have different corporate owners.) The view provided to the crew of the (fictional) Baltic Discoverer is an example of the company's Intelligent Awareness system, which mashes together data from sensors all over a vessel, to give its humans a better view of the world. But that's just the early part of the plan. Using cameras, lidar, and radar, Rolls wants to make completely autonomous ships. And it's already running trials around the world.

"Tugs, ferries, and short-sea transport, these are all classes of vessels that we believe would be suitable for completely autonomous operations, monitored by a land based crew, who get to go home every night," says Kevin Daffey, Rolls-Royce's director of marine engineering and technology. Suitable, because they all currently rely on humans who demand to be paid -- and can make costly mistakes. Over the past decade, there have been more than 1,000 total losses of large ships, and at least 70 percent of those resulted from human error. [...] Moreover, the economic case for automating shipping is clear: About 100,000 large vessels are currently sailing the world's oceans, and the amount of cargo they carry is projected to grow around 4 percent a year, according to the United Nations Conference on Trade and Development. Beyond preventing accidents, human-free ships could be 15 percent more efficient to run, because they don't need energy-gobbling life support systems, doing things like heating, cooking, and lugging drinking water along for the ride.

Alcohol Causes One In 20 Deaths Worldwide, Says WHO (theguardian.com) 211

An anonymous reader quotes a report from The Guardian: Alcohol is responsible for more than 5% of all deaths worldwide, or around 3 million a year, new figures have revealed. The data, part of a report from the World Health Organization, shows that about 2.3 million of those deaths in 2016 were of men, and that almost 29% of all alcohol-caused deaths were down to injuries -- including traffic accidents and suicide. The report, which comes out every four years, reveals the continued impact of alcohol on public health around the world, and highlights that the young bear the brunt: 13.5% of deaths among people in their 20s are linked to booze, with alcohol responsible for 7.2% of premature deaths overall. It also stresses that harm from drinking is greater among poorer consumers than wealthier ones. While the proportion of deaths worldwide that have been linked to alcohol has fallen to 5.3% since 2012, when the figure was at 5.9%, experts say the findings make for sobering reading.

Engineering Firm Plans To Tow Icebergs From Antarctica To Parched Dubai (stuff.co.nz) 412

A Dubai-based engineering firm is planning to tow an iceberg from Antarctica to help provide fresh drinking water to the desert city's rapidly-growing population. Stuff.co.nz reports: The National Advisor Bureau (NABL), a private engineering firm, wants to schlep a glacial iceberg from Antarctica -- weighing approximately 100 million tons -- to Dubai, via an intermediate stop in either Perth, Australia, or Cape Town, South Africa. If the iceberg doesn't melt along the way, the firm will sell the water to Dubai's government. Dubai, which is the most populous city in the United Arab Emirates, is growing so rapidly that a solution to the city's looming water crisis must be found, according to the city's largest English-language newspaper, The Khaleej Times.

The company is beginning a pilot study in November to examine the feasibility of the iceberg-towing project. According to Alshehi, the firm will use satellite imagery to look for a suitable iceberg -- which he says should be between 2000 feet (609 meters) and 7000 feet (2.1 kilometers) long -- and then try and tow it to either Australia or South Africa. Once the iceberg gets to its first stop, it will be towed the rest of the way. Because icebergs are so heavy, the company will need multiple ships to assist with towing, and it will use the ocean's prevailing currents to their advantage. Alshehi told NBC that even if 30 percent of the iceberg melts on the journey, it will still be able to provide between 100 million and 200 million cubic meters of fresh water -- enough for 1 million people to stay hydrated for five years.
Last month, Alshehi told NBC: "If we succeed with this project, it could solve one of the world's biggest problems. So if we show this is viable, it could ultimately help not only the UAE, but all humanity."
