The positional change of nitro­gen-7 of the RNA constituent guanosine to the bridgehead position-5 leads to the base-modified nucleoside 5-aza-7-de­aza­guanosine. Contrary to guanosine, this mol­ecule cannot form Hoogsteen base pairs and the Watson–Crick proton donor site N3—H becomes a proton-acceptor site. This causes changes in nucleobase recognition in nucleic acids and has been used to construct stable `all-purine' DNA and DNA with silver-mediated base pairs. The present work reports the single-crystal X-ray structure of 7-iodo-5-aza-7-de­aza­guanosine, C10H12IN5O5 (1). The iodinated nucleoside shows an anti conformation at the glycosylic bond and an N conformation (O4'-endo) for the ribose moiety, with an anti­periplanar orientation of the 5'-hy­droxy group. Crystal packing is controlled by inter­actions between nucleobase and sugar moieties. The 7-iodo substituent forms a contact to oxygen-2' of the ribose moiety. Self-pairing of the nucleobases does not take place. A Hirshfeld surface analysis of 1 highlights the contacts of the nucleobase and sugar moiety (O—H⋯O and N—H⋯O). The concept of pK-value differences to evaluate base-pair stability was applied to purine–purine base pairing and stable base pairs were predicted for the construction of `all-purine' RNA. Furthermore, the 7-iodo substituent of 1 was functionalized with benzo­furan to detect motional constraints by fluorescence spectroscopy.

Structure-mining finds and returns the best-fit structures from structural databases given a measured pair distribution function data set. Using databases and heuristics for automation it has the potential to save experimenters a large amount of time as they explore candidate structures from the literature.

Short-term exposure to current levels of ozone in many areas is likely to contribute to premature deaths, says a new National Research Council report, which adds that the evidence is strong enough that the U.S. Environmental Protection Agency should include ozone-related mortality in health-benefit analyses related to future ozone standards.

Despite the importance of eyesight, millions of people grapple with undiagnosed or untreated vision impairments — ranging from mild conditions to total blindness — and eye and vision health remain relatively absent from national health priority lists, says a new report from the National Academies of Sciences, Engineering, and Medicine.

Inherent features of registries that rely on voluntary participation and self-reported information make them fundamentally unsuitable for determining whether emissions from military burn pits in Iraq, Afghanistan, and other locations in Southwest Asia caused health problems in service members who were exposed to them, says a new congressionally mandated report from the National Academies of Sciences, Engineering, and Medicine.

The U.S. Environmental Protection Agency (EPA) carries out experiments in which volunteer participants agree to be intentionally exposed by inhalation to specific pollutants at restricted concentrations over short periods to obtain important information about the effects of outdoor air pollution on human health.

The National Academy of Engineering has re-elected Gordon R. England, chairman of PFP Cybersecurity, to serve a two-year term as the NAEs chair.

Introducing drone operations into the nation’s airspace can provide substantial benefits to society, such as preventing derailments, inspecting cell phone towers, delivering medical devices to patients in cardiac distress, and assisting firefighters, says a new congressionally mandated report by the National Academies of Sciences, Engineering, and Medicine.

The Transportation Research Board’s Airport Cooperative Research Program (ACRP) recently selected winners for its University Design Competition for Addressing Airport Needs.

Victoria A. Arroyo, executive director of the Georgetown Climate Center, and Leslie S. Richards, secretary of transportation for the Pennsylvania Department of Transportation (PennDOT), have been appointed as chair and vice chair, respectively, to the 2019 Transportation Research Board (TRB) Executive Committee, which provides oversight of TRB activities.

To achieve goals for climate and economic growth, “negative emissions technologies” (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change, says a new report from the National Academies of Sciences, Engineering, and Medicine.

The U.S. National Academy of Sciences and U.S. National Academy of Medicine joined the science academies of South Africa, Brazil, and Germany today in issuing a statement calling for urgent worldwide action to reduce air pollution.

The U.S. needs stronger policies and guidance to combat Legionnaires’ disease, a form of pneumonia caused by inhaling air contaminated with Legionella bacteria from water systems, says a new report from the National Academies of Sciences, Engineering, and Medicine.

The National Academies of Sciences, Engineering, and Medicine announced today that Harvey Fineberg, former president of the Institute of Medicine (now the National Academy of Medicine) and current president of the Gordon and Betty Moore Foundation, will serve as the chair of the Standing Committee on Emerging Infectious Diseases and 21st Century Health Threats.

As China seeks to control the spread of COVID-19, fewer cars are driving, fewer factories are running and — in some places — skies are clearer.

Air pollution levels have dropped by roughly a quarter over the last month as coal-fired power plants and industrial facilities have ramped down so employees in high-risk areas can stay home. Levels of nitrogen dioxide, a pollutant primarily from burning fossil fuels, were down as much as 30%, according to NASA.

"It is an unprecedentedly dramatic drop in emissions," says Lauri Myllyvirta, lead analyst at the Centre for Research on Energy and Clean Air, who tallied the reductions. "I've definitely spoken to people in Shanghai who said that it's been some of the most pristine blue skies that they remember over the winter."

Myllyvirta estimates that China's carbon emissions have dropped by a quarter over the same period. While that's a tiny fraction of its overall annual emissions, it's substantial in a worldwide context, since China is the largest emitter of greenhouse gases.

There's potentially a health benefit — although any gains due to a drop in pollution are set against the toll taken by the coronavirus outbreak.

Air pollution is estimated to contribute to more than 1 million premature deaths in China each year. Fine particle pollution, also known as PM 2.5, can enter the bloodstream through the lungs and has been linked to asthma attacks, heart attacks and respiratory problems.

Even a short-term reduction in air pollution can make a difference.

"There is no question about it: When air quality improves, that will be associated with a reduction in health-related problems," says Jim Zhang, professor of global and environmental health at Duke University.

Zhang says that was evident during the 2008 summer Olympics in Beijing. To help improve the air, government officials shut factories and dramatically limited car travel before and during the games. Levels of some air pollutants dropped by half.

He and colleagues studied a group of young men and women in Beijing and found that during that time period, their lung and cardiovascular health improved. He also followed pregnant women.

"What we found is that the kids whose mothers had a third trimester pregnancy during the Olympics when the air quality was better, their birth weight was substantially higher than the kids who were born a year before and a year later," he says.

But health specialists sound a cautionary note.

"It would be a mischaracterization to say that the coronavirus was beneficial to health because of these air pollution reductions," says Jill Baumgartner, associate professor and epidemiologist at McGill University.

"The health impacts from the virus itself, the stress on the health-care system, the stress on people's lives — those health impacts are likely to be much greater than the short-term benefits of air pollution on health," she says.

Baumgartner says people with health issues other than COVID-19 may have avoided seeing doctors during the outbreak or potentially couldn't receive treatment they needed in areas with overtaxed health systems.

Those isolated at home and avoiding crowds may also have been exposed to more indoor air pollution.

"People spent a lot more time indoors and it's possible that they were exposed to higher levels of indoor tobacco smoke," Baumgartner says. "Or in the suburban areas, it's possible that they were using their traditional wood or coal stoves for heating."

Not all cities have experienced the recent improvements. In mid-February, Beijing saw a spike in pollution due to local weather patterns trapping air in the region.

The drop in air pollution and carbon emissions is also likely to disappear as Chinese industry ramps up again in an attempt to offset its economic losses.

"If you think back to the global financial crisis, the immediate impact was for China's emissions to fall," says Myllyvirta. "But then the government response was to roll out the biggest stimulus package in the history of mankind that then drove China's emissions and global emissions up for years."

A lot is at stake for students taking Advanced Placement exams, even in normal times. If you score high enough, you can earn college credit. It's also a big factor in college applications. But for some students, the idea of studying right now feels impossible.

"I'm constantly thinking about making sure my family doesn't get sick and I don't get sick," says Elise, a high school junior outside Boston. (We're not using her full name because she's worried about hurting her college applications.)

Concerns about the coronavirus have put most standardized tests, such as the SAT and ACT, on hold this spring. But AP exams are going forward with a new online format — and that's raising questions about fairness.

Elise, 17, says she spent months preparing for what is typically a three-hour, multiple-choice and essay-based exam; she was blindsided when she learned it will now be an online, 45-minute, open-response test.

"I have no idea what I'm going to get when I open that test," she says.

Elise was hoping the College Board, which administers AP exams, would cancel this year's exams, as it did the spring SATs. But since the tests are being offered, she says she feels she has to take them. She worries it would look bad on her college applications if she opted out.

For other students, just the idea of taking the exam at home is causing anxiety. Kayleen Guzman, 17, from Boston says it's hard to find peace and quiet in her house right now.

"Currently, it's me, my mom, my dog, my sister and my stepdad," she explains. "Sometimes I feel like it's too much chaos."

But Guzman is glad she still has the opportunity to take the AP exams at all this year. She says she worked hard in her two AP classes and she wants the chance to earn college credit.

However, it's still unclear how much credit colleges will give students for this year's exams.

"None of us would say that we are confident that a 3 or 4 or 5 on the AP exam this year means the exact same thing as a 3, 4 and 5 on the exam last year," says Harvard University's Andrew Ho, who studies the reliability of educational tests.

Ho says that because of the new format, this year's AP exams won't be measuring the same thing as previous years' exams. For one, the new tests will cover less material. And changing where kids take it — from a proctored classroom to their laptops at home — is a big deal. But Ho adds, "Just because it's not completely comparable doesn't mean the College Board and colleges, through their own policies, couldn't adjust."

Some colleges are already adjusting. The University of California system has come out explicitly to say it won't change the way it credits AP scores. Other colleges that didn't want to go on the record say they are planning to change their policies, but the details weren't ready to share just yet.

In a statement, College Board spokesperson Jerome White said the organization decided to move forward with AP testing to give motivated students the opportunity to earn college credit. He added that the organization is making "a significant financial investment" to make the exams available online, from cheating prevention software to helping students who may not have an Internet connection or access to a computer.

Still, some educators worry that those efforts won't be enough.

"This situation has created a lot of distraction," says Savannah Lodge-Scharff, an AP Physics teacher for Boston Public Schools. She argues that without in-person classes, many students won't be able to engage with the material in the same way. On top of that, financial stress means many of her students are juggling additional responsibilities, like taking care of siblings.

"I have some of my students who are working 40, 50, 60 hours a week at the grocery store right now in the fear their parents are going to be laid off," she explains.

And then there's the question of geographic equity. This year's exams will be administered at the same time worldwide, meaning students in Hong Kong will be up at midnight to take it.

There are 162 games in the regular season of a major league baseball team, and I have watched exactly … hm … none. Spring, summer, autumn, as the Dodgers died and rose from the dead, I wasn’t looking.

But now, like almost everyone else in L.A., I will be cheering them in the playoffs, cheering them to their first World Series game since Michael Dukakis ran for president.

I am that deplorable creature: The fair-weather fan.

I like sports just fine, but my sport is football.

They say baseball is a relaxing game. Boy, is it!  You can eat, doze, eat again, and it’s still the fourth inning. I’ve tried to love baseball, I really have. But the diamond can’t beat the gridiron when it comes to football’s built-in thrill advantage: At any possible second, the football can change hands, the defense becomes the offense … and score!

Just about the best time I ever had at Dodger Stadium was watching the pope round the bases in his Popemobile, when he visited L.A. That was the year before the Dodgers won the World Series for the last time. I hear baseball players are superstitious; maybe it’s time to invite the new pope for a return engagement.

Kitty Felde – now there’s a fan. She’s even written plays about baseball! But she’s way back in the nation’s capital, stuck with the Washington Nationals to root for.

A paradox

It’s a paradox, really. I’ve interviewed the former Dodgers owner, Peter O’Malley, who is a truly wonderful man. I’ve interviewed Carl Erskine, the Dodgers pitcher who goes back to the Brooklyn days, and a sweeter guy you could never meet. I know Roz Wyman, the First Fan, the city councilwoman who worked the magic to bring the Dodgers here from Brooklyn.  I interviewed the McCourts, back when they were still a plural. The L.A. Times once sent me to write about Fernando Valenzuela’s hometown in Mexico, back when El Zurdo started burning up the mound at Chavez Ravine. And I sat with that gift of a man, Vin Scully, at Dodger Stadium, as the team warmed up on the jewel-box beautiful field.

None of that made a true baseball believer of me. Instead, I pine like Juliet for a pro football team. O Dodgers, Dodgers, wherefore art thou the Dodgers, and not the Green Bay Packers?

But I would be thrilled if the Dodgers took the whole baseball enchilada – thrilled, because I am an Angeleno, and the Dodgers are that rare civic institution that ties us all together, even if you don’t know a base hit from base ten.

And that makes me as entitled as the next local to put on my Dodger Blue and holler my heart out, and cheer them all the way to the World Series.

Oracle says Larry Ellison is stepping aside as CEO of the company he founded. The business software maker promoted Safra Catz and Mark Hurd to replace him as co-CEOs.

Ellison will reclaim the title of chairman at Oracle and is also taking the role of chief technology officer. Oracle says Ellison wants to focus on product engineering, technology development and strategy. Jeff Henley, Oracle's chairman since January 2004, is now its vice chairman.

Catz and Hurd were co-presidents of the Redwood Shores, California, company. Catz will be in charge of the company's manufacturing, finance and legal functions. Hurd will be in charge of sales, service, and other global business units.

Ellison founded Oracle Corp. in 1977 and was its chairman from May 1995 to January 2004.

As Los Angeles mulls a law that would raise the minimum wage above the current California minimum of $9 an hour, it's the latest city to jump on a trend that started as the by-product of a failed labor negotiation in the state of Washington.

The first city to enact a $15-per-hour minimum wage was SeaTac, Wash., — a tiny airport town outside Seattle. "SeaTac will be viewed someday as the vanguard, as the place where the fight started," the lead organizer of SeaTac's $15 campaign, David Rolf, told supporters in November 2013 after a ballot measure there barely passed.

Rolf never set out to raise SeaTac’s minimum wage, much less start a national movement. Speaking from a sparse corner office in downtown Seattle at the Service Employees International Union 775, which he founded in 2002, Rolf told KPCC that his original goal in 2010 was to unionize workers at SeaTac airport.

When employers – led by Alaska Airlines — played hardball, Rolf put the $15 minimum wage on the ballot as leverage. “We had some polling in SeaTac that it could pass, but it was not at all definitive,” Rolf said.

That proved prescient: In a city of just 12,108 registered voters, Rolf's staff signed up around 1,000 new voters, many of them immigrants who had never cast a ballot. The measure won by just 77 votes.

It's an irony that the new law doesn't apply to workers at the center of the minimum wage campaign: The airport workers at SeaTac. That's because the Port of Seattle, which oversees the airport, challenged the initiative, arguing that the city's new minimum wage should not apply to the nearly 5,000 workers at the airport. A county judge agreed. Supporters of the $15 wage have appealed.

Still, Rolf said, "I think people are proud that that’s what happening. There are leaders of the movement in Seattle, including our mayor, that said shortly after the victory, 'Now we have to take it everywhere else.'"

The $15 minimum wage spread to Seattle last June and to San Francisco in November. 

Why $15 an hour?

The $15 figure first came to people’s attention in a series of strikes by fast food workers that started two years ago in New York. 

“I think it’s aspirational, and it provides a clean and easy-to-understand number," Rolf said. "You can debate whether it ought to really be $14.89 or $17.12, and based upon the cost of living in different cities, you could have a different answer. But in the late 19th and early 20th century, American workers didn’t rally for 7.9 or 8.1 hour working day. They rallied for an eight-hour day.”

“What’s really remarkable about social protest movements in American history is that the radical ideas of one group are often the common sense ideas of another group in a matter of a few years," said Peter Dreier, professor of politics at Occidental College.

Rolf is hopeful the $15 minimum wage can spread to every state. But Nelson Lichtenstein, Director of the Center for the Study of Work, Labor and Democracy at the University of California, Santa Barbara, is skeptical.

“I don’t think having high wages in a few cities will mean it will spread to red state America,” he said. 

Lichtenstein said cities like L.A. have become more labor friendly, thanks largely to an influx of immigrants, but that’s not the case in the South. Oklahoma recently banned any city from setting its own minimum wage, joining at least 12 other states with similar laws, according to Paul Sonn, general counsel and program director at the National Employment Law Project.

In November, voters in four Republican-leaning states — Alaska, Arkansas, South Dakota, and Nebraska — approved higher minimum wages, but they weren’t close to $15.

A $15 dollar wage would have a much greater impact in Los Angeles than Seattle or San Francisco because the average income here is much lower than in those cities. Post-recession, income inequality has become much more of a concern for voters, which has made $15 more palatable, Sonn said.

This fall, the Los Angeles City Council enacted a $15.37 minimum wage for hotel workers that takes effect next year. A similar law has been in effect around LAX since 2007. 

But even though California cities have been allowed to set their own minimum wages for more than a decade, L.A. has never come close to doing so.

Until now.

Here’s a pop quiz: What is the world’s busiest airport?

Almost two weeks ago, Chicago's O'Hare International claimed the honor.

"As Chicago reclaims its place with the world’s busiest airport, it speaks to the strength of our city’s economy," bragged Chicago Mayor Rahm Emanuel.

Not so fast, said Dubai, which last week said it was number one.

“This historic milestone is the culmination of over five decades of double-digit average growth," announced HH Sheikh Ahmed Bin Saeed Al Maktoum, Chairman of Dubai Airports.

Then, on Wednesday, Atlanta weighed in, and yes, it also claimed to be the champion.

“I am pleased to announce that once again – for the 17th year in a row – Hartsfield-Jackson Atlanta International Airport is the busiest airport on Planet Earth, with more than 96.1 million passengers,” Atlanta Mayor Kasim Reed said. 

Airports Council International ranks Atlanta as number one in passenger traffic, but those are based on 2013 numbers. The group's 2014 numbers will be out in a few months, but until then we know that LAX proudly takes an undisputed sixth place.

Gina Marie Lindsey, Executive Director of the Los Angeles World Airports, announced her retirement Tuesday after a 33-year career in the aviation industry. Since Lindsey started in 2007, passenger traffic has grown by 15 percent. 

Aviation consultant Jack Keady doesn’t think LAX stands a chance of competing with rapidly expanding Dubai, which state-owned Emirates airlines has made its glitzy global hub.

"Dubai has bumped everyone down,” said Keady.

Still, Keady says LAX will keep growing, even though it’s going to be working with the same number of runways for the foreseeable future.

“Instead of running 30-passenger turboprops and 100-passenger planes, you start bringing in the heavy metal,” said Keady.

Bigger planes are especially important because under a 2006 settlement with airport neighbors, once LAX hits 75 million passengers, it has to start closing gates.

More than 70 million passengers travelled through LAX last year, an all-time record.

Global air quality will significantly deteriorate by 2050 unless further steps are taken to cut current emissions from human activities, according to recent research. Most people around the world will be affected by worsening air quality with hotspots of particularly poor air occurring in China, northern India and the Middle East.

Researchers have developed a new model to assess the health-related external costs arising from air pollution from ten major emission sectors. Applying the model at national and Europe-wide levels, they suggested that the major contributors to costs were industrial power production, agriculture, road traffic and domestic combustion.

The impact of air quality on public welfare is important to policy development. However, it is difficult to make a clear link between the two when air pollution tends to be reported at a country level and wellbeing is an individual measure. A new study takes a step further towards linking the two by analysing regional level air quality across the EU and relating it to levels of life satisfaction.

Researchers at the Stowers Institute have established a definitive link between the makeup of the microbiome, the host immune response, and an organism's ability to heal itself.

Improving the efficiency of milk production could produce significant annual savings and potentially cut the environmental impacts of the industry by up to a third, according to new research from Northwest Spain.

The damaging health impacts of some key air pollutants can occur at lower atmospheric concentrations than indicated by the most recent World Health Organization (WHO) Air Quality guidelines, set in 2005 and currently used in Europe. This is according to a new WHO report, which assesses scientific evidence to help inform European air pollution policies.

The impact of air quality on public welfare is important to policy development. However, it is difficult to make a clear link between the two when air pollution tends to be reported at a country level and wellbeing is an individual measure. A new study takes a step further towards linking the two by analysing regional level air quality across the EU and relating it to levels of life satisfaction.

Continued reductions in air pollution and greenhouse gas (GHG) emissions are essential, as they pose serious threats to both people's health and the environment across the world. Air quality and climate policies can provide mutual benefits and there can also be trade-offs. This thematic issue reports on research which helps us understand the relationship between air pollution and climate change and how the two policy areas can be integrated to produce the greatest results.

A recent study suggests that exposure to aircraft noise during the day has a greater impact on cognitive ability in children than sleep-disruption caused by exposure to aircraft noise during the night. Protective policy is therefore likely to be most effective if focused at the school level.

Surveys have suggested that the public have become more annoyed by aircraft noise over recent decades. A recent study has investigated whether these results are partly caused by changes in survey methods and participants. However, no methodological issues considered could satisfactorily explain the rise in reported levels of annoyance at a given noise exposure level.

Companies that adopt the environmental management system ISO 14000, designed to help reduce businesses’ environmental impacts, generally back this up with sincere investment in environmentally-friendly practices, research suggests. Researchers found that adoption of the ISO 14000 was not ‘greenwash’, but reflected a move towards more sustainable practices in both European and North American companies.

Exposure to aircraft noise at night for more than 20 years could increase the risk of heart disease and stroke, according to research conducted around six European airports. Risk also increased for those constantly exposed to road traffic, but this may have been caused by air pollution rather than noise.

Recent research into the impact of different levels of noise on 75 volunteers reveals that disturbed sleep caused by night-time aircraft noise can damage blood vessels and increase the levels of stress hormones. As these physical changes are potential pathways to high blood pressure, heart and circulatory disease over the long term, reducing night-time aircraft noise is important for preventing cardiovascular disease in people living near airports.

Residents living within half a mile of unconventional natural gas wells may have an increased risk of illness from exposure to air pollution from the wells, according to a recent study. The peer-reviewed study recommends that risk prevention efforts to minimise impacts on human health should concentrate on communities living and working close to wells during well completions and that further studies on health effects of exposures to air emissions from such projects should be carried out.

Periods of slow growth observed in coral reefs in the Caribbean are caused by aerosols in the air from pollution and volcanic activity, recent research suggests. Aerosols cause cooler sea surface temperatures and reduce the amount of sunlight reaching the coral, both of which slow coral growth.

European policies have eliminated the most visible and harmful effects of air pollution, but current rates of emissions still pose a threat to the environment and to human health. A new study has assessed the policy scope to make further environmental improvements by applying the GAINS (Greenhouse gas-Air pollution Interactions and Synergies) model.
