DOI: 10.1126/science.1207824AbstractMegacities are immense sources of air pollutants, with large impacts on air quality and climate. However, emission inventories in many of them still are highly uncertain, particularly in developing countries. Satellite observations allow top-down estimates of emissions to be made for nitrogen oxides (NOx = NO + NO2), but require poorly quantified a priori information on the NOx lifetime. We present a method for the simultaneous determination of megacity NOx emissions and lifetimes from satellite measurements by analyzing the downwind patterns of NO2 separately for different wind conditions. Daytime lifetimes are ~4 hours at low and mid-latitudes, but ~8 hours in wintertime for Moscow. The derived NOx emissions are generally in good agreement with existing emission inventories, but are higher by a factor of 3 for the Saudi Arabian capital Riyadh. © 2011 Citation: Most accurate measurements of big-city pollution (2011, September 23) retrieved 18 August 2019 from ( — One of NASA’s satellites has provided the most detailed map yet of the pollution generated by some of the world’s biggest cities, and given an indication of the volume of emissions of the nitrogen oxides from direct measurements rather than relying on computer models and a range of assumptions. The scientists, from Germany and the Netherlands, led by Steffen Beirle of the Max Planck Institute for Chemistry in Mainz, Germany, combined the data from NASA’s Aura satellite with data on known wind patterns. The satellite is equipped with four measuring instruments, including an Ozone Monitoring Instrument (OMI), which measures a range of atmospheric particles such as dust, smoke, and chemicals such as the nitrogen oxides. It also measures cloud cover and pressure, which enables tropospheric ozone to be calculated. The OMI was built by the Agency for Aerospace Programs in the Netherlands and the Finnish Meteorological Institute.The focus of Beirle’s study was the nitrogen oxides (NOx, comprising nitric oxide, NO, and nitrogen dioxide, NO2), since they contribute to smog, acid rain, and ozone depletion, and have been linked to health problems in human populations.Nitrogen oxides form part of vehicle emissions, and in the past have tended to be estimated from data on traffic volumes, fuel consumption, and NOx lifetimes, rather than by direct measurement. The satellite data gave the researchers a direct measurement of the emissions, and the data on wind patterns enabled them to identify the sources, resulting in the most accurate information available to date.The study, published in the journal Science, found that the emissions of nitrogen oxides from Riyadh (the capital of Saudi Arabia) were three times greater than previous estimates, while those of megacities such as Tokyo, Madrid, and Moscow were more similar to previous estimates. Some megacities, such as Hong Kong and New York, yielded less useful data because they are so close to other large metropolitan areas producing pollution, which makes the situation more complex.The results of the research could help scientists obtain more reliable information that does not depend on models, which can introduce biases. The results could also lead to the development of better pollution control measures, especially for large cities in the developing world.The Aura satellite was launched in 2004 as part of a program aimed at monitoring the Earth’s atmosphere and effects such as the depletion of the ozone layer. Among the other atmospheric measurements made are changes in levels of aerosols, carbon dioxide, water vapor, and methane. The satellite also monitors cloud cover around the globe.

How fledglings and their parents negotiate the best time for young birds

first_imgA team of researchers at the University of Montana has found that fledglings and their parents must negotiate to find the right time for the young birds to leave their nest. In their paper published on the open access site Science Advances, the group describes their study of many types of birds and how they figured out when fledglings should leave the nest. Journal information: Science Advances © 2018 Many birds build nests to lay their eggs and to hold the young after they hatch until they grow old enough to fly on their own. But how do the baby birds and their parents know when it is time for them to leave? That question, the researchers point out, has not been studied very much. For that reason, they designed and carried out a study to find the answer.The study consisted of videotaping 11 types of songbirds using a high-speed camera—that allowed them to gain a better understanding of the flying skills of birds. They also watched as the birds grew older and carefully noted the time points at which the young birds left the nest—and how they fared.The researchers found that there were differences between species—some parents allowed their offspring to stay in the nest longer while others did not. There were also differences in mortality rates between species. Those that left the nest earlier found it tougher going than those that stayed in the nest longer—fewer of them survived because they had not yet developed strong flying skills. On the other hand, young birds that hung around in the nest longer were more likely to attract predators because they were noisier—increasing the likelihood of the whole brood being eaten. The researchers also found that under artificial conditions in which they forced some parents to keep their young in the nest for a few extra days, the mortality rate was lower—not only did the young birds have more time to develop, they were also protected from predators.

Martin et al. Age and performance at fledging are a cause and consequence of juvenile mortality between life stages, Science Advances (2018). DOI: 10.1126/sciadv.aar1988AbstractShould they stay or should they leave? The age at which young transition between life stages, such as living in a nest versus leaving it, differs among species and the reasons why are unclear. We show that offspring of songbird species that leave the nest at a younger age have less developed wings that cause poorer flight performance and greater mortality after fledging. Experimentally delayed fledging verified that older age and better developed wings provide benefits of reduced juvenile mortality. Young are differentially constrained in the age that they can stay in the nest and enjoy these fitness benefits because of differences among species in opposing predation costs while in the nest. This tension between mortality in versus outside of the nest influences offspring traits and performance and creates an unrecognized conflict between parents and offspring that determines the optimal age to fledge.

Play Gray-headed juncos fledge from the nest at a young age because their ground nests experience high risk of predation. This young age of fledging results in under-developed wings that do not allow sustained flight, even the day after they left the nest, as shown in this video. In contrast, white-breasted nuthatches nest in safe cavities with low predation risk, allowing young to stay in the nest longer and develop their wings more fully such that they can perform sustained level flight even 2 days before they fledge.

The heel logic

first_imgA pair of high heels is like a must for every women as it makes them look chic and classy. But carrying it off is difficult as it puts them into difficult situations, says a research.Research from Compeed, a foot-care brand, has found that nearly half those women trying to arrive at work looking their best, get their heels caught in a grate, over a third have fallen over and 29 percent have tripped up the stairs, reports The survey, which offers a comparison of high heel wearers across Europe, reveals its hazards are adding to commuting times. But it appears as if nothing will prevent some women from doing the daily commute in their high heels – 58 percent of British women will wear heels even if they are painful or uncomfortable and 13 percent admit they wear their heels even if it makes them late for the office.The survey also reveals reasons why women are prepared to sacrifice both comfort and punctuality for high heels.

Participants were asked to weigh pros, like improved energy and health, against perceived disadvantages, like being tired and not having enough time for academics or leisure. Once convinced that more exercise would benefit them, students were asked what they needed to get started. The single most significant factor was behavioural confidence which involves visualisation of future performance and external sources of confidence like an encouraging mentor. Also Read – Over 2 hours screen time daily will make your kids impulsiveAccording to the survey, respondents indicated that sustaining the weekly 150 minutes of exercise would require the support of family and friends, as well as an emotional shift, in which students would use exercise as an outlet for stressors. Respondents also said that social changes like making friends who also exercise regularly would improve their ability to persist. “Nearly half of all adults in the US do not engage in the recommended 150 minutes of physical activity per week. This basic lack of exercise is tied to myriad health problems, so it is important to address it early,” said study lead author, a Professor at the Jackson State University.last_img read more

Toxic Author Rare Books Found to be Laced With Arsenic in a

first_imgIn a plot twist out of Umberto Eco’s The Name of the Rose, three rare books from the 16th and 17th centuries held in a library collection were found to be laced with deadly poison, according to a paper published on June 27, 2018, by researchers of the University of Southern Denmark. The last thing that the researchers expected was poison.“The reason why we took these three rare books to the X-ray lab was because the library had previously discovered that medieval manuscript fragments, such as copies of Roman law and canonical law, were used to make their covers,” wrote Jakob Povl Holck and Kaare Lund Rasmussen in the academic journal The Conversation. “It is well documented that European bookbinders in the 16th and 17th centuries used to recycle older parchment.”To discover the possible age of the recycled materials contained in the cover and bindings of the books stored at the University of Southern Denmark, the researchers used the most modern technology available: a series of X-ray fluorescence analyses (micro-XRF).University of Southern Denmark.“This technology displays the chemical spectrum of a material by analysing the characteristic “secondary” radiation that is emitted from the material during a high-energy X-ray bombardment,” wrote Holck and Rasmussen. “Micro-XRF technology is widely used within the fields of archaeology and art, when investigating the chemical elements of pottery and paintings, for example.”While trying to identify the Latin texts used in the books, the researchers were frustrated by a layer of green paint that obscured the old handwritten letters.The researchers were trying to read medieval Latin manuscripts that were used as covers for the three books.They decided to analyze the mysterious paint, and XRF tests revealed “that the green pigment layer was arsenic. This chemical element is among the most toxic substances in the world and exposure may lead to various symptoms of poisoning, the development of cancer and even death.”Depending on the type of arsenic used and the duration of exposure, symptoms of arsenic poisoning include an irritated stomach, irritated intestines, nausea, diarrhea, skin changes and irritation of the lungs. The exposure’s harmful effect has not gone away, either.Why would anyone use poisonous paint on these obscure books?The answer seems to lie in the 19th century. Arsenic was commonly used to create the “Paris green” paints and lacquers and was most likely employed on these books by well-meaning restorers.10 Most Poisonous Things on Earth!Wrote the university researchers: “The arsenic pigment – a crystalline powder – is easy to manufacture and has been commonly used for multiple purposes, especially in the 19th century. The size of the powder grains influence on the colour toning, as seen in oil paints and lacquers. Larger grains produce a distinct darker green – smaller grains a lighter green. The pigment is especially known for its colour intensity and resistance to fading.”Why would anyone want to improve the aesthetics of 17th century books?Arsenic trioxide is a white, crystalline powder that closely resembles sugar. It has no odor or taste.Most likely, artistic effect was not the only thing on their minds in the 19th century. There was a byproduct of using the “Paris green” color: it protected manuscripts against insects, rats, and other vermin.

VIDEO Sidebyside video of Mayweather and McGregor training proves McGregor has no

first_imgConor McGregor and Floyd Mayweather each released the first videos of them training for their upcoming August 26 publicity stunt. If you watch them side-by-side, the difference in the boxing skill from the two jumps off the screen.The 49-0 Mayweather looks like he hasn’t lost much in his “retirement” and still looks lighting quick. McGregor, on the other hand, looks like a slow UFC fighter who’s throwing punches in quick drying cement. You don’t have to be Bert Sugar to see that McGregor is going to get dismantled by Mayweather. The only real question is will he get knocked out.Anyone who says they believe McGregor can win this fight after watching this side-by-side is either a fool or a liar. This is going to be a massacre.Mayweather and McGregor training videos from today side by side. ?— BlackSportsOnline (@BSO) June 29, 2017 Advertisementlast_img read more

New 4G Technology Might Wipe Out Your WiFi Connection

first_img Growing a business sometimes requires thinking outside the box. July 8, 2015 Mobile networks and Wi-Fi have long occupied their own distinct territories on the airwaves. Cellular operators stick to licensed spectrums, which they typically pay billions to use exclusively. Meanwhile, Wi-Fi takes advantage of a vast swathe of spectrum known as the unlicensed airwaves, which costs nothing. That distinction is one of the main reasons why connecting to Wi-Fi is cheap and often free, while connecting to a mobile network is not.The line between Wi-Fi and mobile has existed for two decades, and it’s produced enormous growth and innovation in both industries, but mobile operators are now changing the game by crossing over into Wi-Fi’s turf. A new technology called LTE-Unlicensed, or LTE-U, will allow mobile carriers to dip into unlicensed frequencies for additional capacity, essentially creating 4G networks in Wi-Fi’s airwaves. This has the Wi-Fi industry worried, and has ended up pitting mobile industry giants like T-Mobile, Verizon and Qualcomm against Wi-Fi advocates like Google, Cisco Systems, and other cable providers“The worse case scenario is that LTE operates in unlicensed spectrum in a way that does not pay due regard to other users, making the Wi-Fi experience significant degraded,” said Edgar Figueroa, president and CEO of the Wi-Fi Alliance, a global non-profit that supports Wi-Fi technologies. “In such a case, bandwidth is eliminated from use by Wi-Fi because it’s being used exclusively by LTE.”The ins and outs of unlicensed airwavesBefore you jump all over mobile operators, keep in mind that they have every right to use these airwaves. The 2.4 GHz and 5 GHz frequency bands are called “unlicensed” for a reason. Everyone is free to use these frequencies, regardless of whether or not they’re an operator adding bandwidth to a 4G network or a just an average Joe setting up a Wi-Fi router in your home.However, there are some rules everyone using these frequencies must follow. First, users must transmit at low power, which is why Wi-Fi’s weaker signals won’t cover much more than your apartment. Second, if there are other nearby users trying to use the same frequencies then individuals will have to share.Wi-Fi does this sharing through a protocol called, quite simply, Listen Before Talk. A Wi-Fi network is constantly scanning its environment looking for competing signals. If it detects them, it doesn’t transmit, waiting several milliseconds before trying again. It’s the same basic principle as talking at a dinner party. Everyone waits their turn to speak rather than everyone trying to talk all at once.This kind of frequency sharing allows multiple Wi-Fi networks to live in the same physical space, and it’s been one of the key reasons for Wi-Fi’s huge proliferation. Wi-Fi isn’t the unlicensed band’s only tenant, though. It has to share the same space with Bluetooth, cordless phones, wireless remotes and even baby monitors, but for the most part those technologies have managed to co-exist peacefully. The introduction of LTE-U, though, represents a major new incursion into unlicensed airwaves.LTE-U basically is intended to supercharge our mobile connections in places where mobile data demand is the highest. LTE-U combines your regular connection to the 4G network with a new transmission in the unlicensed band, effectively doubling your bandwidth. For example, if you were humping along with a 10 Mbps link and suddenly entered an LTE-U coverage area, you would find your connection speed boosted to 20 Mbps or more.Due to the low-power requirements for unlicensed bands, operators can’t use LTE-U everywhere. Mainly it’s an indoor technology, but inside of buildings is exactly where the vast majority of mobile data consumption happens today. LTE-U could add a lot of capacity to an operator’s networks, and because operators wouldn’t have to sink billions of dollars into buying airwaves, they could deliver all of that capacity at a much lower cost, which could—at least, theoretically—be passed on to consumers.Why Wi-Fi is freaked outWi-Fi Alliance’s Figueroa has made it clear he doesn’t want to boot the mobile operators out of the unlicensed airwaves, which would be antithetical to the idea of shared band. What he and other Wi-Fi advocates want is to ensure that LTE plays by the same rules as the band’s other users currently do.In fact, the Alliance and other Wi-Fi standards groups are working closely with their mobile industry counterparts to create a standardized technology similar to LTE-U called LTE-Licenses Assisted Access. LTE-LAA would employ the same Listen Before Talk protocols as Wi-Fi, which Figueroa believes will allow the two technologies to co-exist peacefully.The problem is LTE-LAA gear and chips won’t be commercial available for several years, and mobile operators in several countries—notably the U.S., South Korea and India—don’t want to wait. Both Verizon and T-Mobile US plan to roll out LTE-U network gear and devicesin 2016.LTE-U uses a less stringent sharing protocol than Listen Before Talk, and the Wi-Fi industry fears that it will give mobile operators an unfair advantage, effectively muscling Wi-Fi users off their networks. According to comments Google filed with the Federal Communications Commission, an LTE-U transmission sharing the same frequency channel with a Wi-Fi transmission could degrade the Wi-Fi connection as much as 75%. The result, according to Google, would be a much better experience for users on the mobile network, but a much crappier experience for users on Wi-Fi.One of LTE-U’s biggest backers, Qualcomm, has dismissed those fears. The telecom company argues that while LTE-U uses a different sharing protocol than Wi-Fi’s Listen Before Talk, it’s perfectly adequate to ensure that Wi-Fi and LTE-U cooperate peacefully, said Prakash Sangam, Qualcomm director of technical marketing. Furthermore, Qualcomm has a vested interest in keeping Wi-Fi safe, Sangam said, since the company has its own Wi-Fi technology division, Atheros, so creating a technology that would run amuck in the unlicensed frequencies would cannibalize one of its major businesses.“Fair co-existence with Wi-Fi has been our main concern since we started the design phase on LTE-U,” Sangam said.He added that LTE-U actually might be a better neighbor to Wi-Fi than Wi-Fi itself. Typically Wi-Fi access points in any given location act independently, creating a constant over-the-air negotiation for signals. In contrast, LTE-U is part of an operator’s centrally managed cellular network. This type of arrangement would mean LTE-U access points would coordinate their activities in crowded airwaves, making more efficient use of the frequencies available and improving the data experience for Wi-Fi and LTE users alike.However, the Wi-Fi industry has a different view about that kind of centrally managed network. Instead of using that central coordination to the benefit of Wi-Fi, LTE-U could use that capability to force Wi-Fi networks off the air, much like the individual cars on a racing team can cooperate to pass competing cars on a track.Solving the impasseThe public will eventually find out if the Wi-Fi industry’s fears are warranted when T-Mobile  and Verizon’s LTE-U networks go live next year, although Wi-Fi advocates don’t want to wait that long. They’re asking the FCC to step in now, and put restrictions on the types of radio technologies operators can use in the unlicensed bands.Even if the Wi-Fi and mobile camps sort out their differences and find a way to fairly share the unlicensed frequencies, there will still be some big repercussions for both industries. A lot of our smartphone traffic today already rides over Wi-Fi networks, but as LTE-U goes live you can expect some of that traffic to shift back onto mobile networks. While Wi-Fi access is largely free today, mobile operators charge for their data connections.Also, the unlicensed band is going to get a lot more crowded. LTE-U will become a major new tenant on the unlicensed band, and regardless of how well it cooperates with Wi-Fi, space is going to get a bit tight. Anyone who’s tried and failed to connect to a Wi-Fi hotspot at a crowded coffee shop or conference center, knows there’s already a limited amount of unlicensed bandwidth to go around.Ultimately, a move onto Wi-Fi’s turf by mobile operators demonstrates just how much interest there is for finding new uses for the unlicensed bands. Maybe, the government should take the hint and open up more airwaves not just for Wi-Fi, but for everyone.

Got Effective Cybersecurity Practices Be Aware The FTC Is Watching You

first_img Opinions expressed by Entrepreneur contributors are their own. Register Now » Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right. Following a July ruling against medical testing laboratory LabMD (which is now out of business), the Federal Trade Commission has emerged as a central regulator of cybersecurity practices for U.S. businesses. The FTC’s mandate to act on “unfair or deceptive” business practices that could harm consumers is being interpreted in a way that means any business that handles (and might potentially mishandle) consumer data is liable to fall under the organization’s scrutiny.That’s almost every business today.Related: 5 Cybersecurity Tools Your Company Should HaveSome background: The Commission reversed an administrative law judge’s ruling and found that LabMD, a clinical laboratory for physicians, failed to protect the sensitive personal and medical information of consumers. From 2001 to 2014, LabMD collected this information for over 750,000 patients.Based on the LabMD ruling, which cited a lack of “even basic precautions to protect the sensitive consumer information maintained on its computer system,” it appears that actual harm from a data breach doesn’t necessarily need to be proven if the potential for harm exists.The ruling sends a clear and sobering signal to business owners: You must make significant, demonstrable efforts to protect yourself from data breaches or face the consequences.Related: Court Rules FTC Can Come After Your Company After a Cyber AttackA glimpse of what’s to come“LabMD’s security practices were unreasonable, lacking even basic precautions to protect the sensitive consumer information maintained on its computer system,” the FTC ruled. “Among other things, it failed to use an intrusion detection system or file integrity monitoring; neglected to monitor traffic coming across its firewalls; provided essentially no data security training to its employees; and never deleted any of the consumer data it had collected.”For small business owners who have a seemingly endless list of concerns to address, making time to focus on data security best practices is sometimes difficult to justify. But it has to be done: The FTC and other government entities are only going to sharpen their focus on data security and consumer privacy in the coming years. Data integrity must become a core aspect of doing business (rather than a minor detail that can be overlooked).With this in mind, small business owners should be aware of a few common misconceptions surrounding data security, as well as the best practices they should rely on to address them:Misconception No. 1: Data security is a ‘big business’ problem.A surprising number of small business owners look at data security as something they don’t need to worry about. You’ll hear owners say, “Nobody is interested in the data we have. We’re not Sony or a government agency.”But the truth is that cybercriminals are most certainly interested in your data, and according to Fox Business, 43 percent of worldwide attacks in 2015 were against small businesses with fewer than 250 employees.On top of that, the prevalence of ransomware attacks means that it no longer matters if your data is important to other people. If it’s important to you — the owner — hackers can take it and force you to pay large sums of money to get it back.As a small business owner, you must consider it critical to have a managed-data backup system in place. This won’t prevent attacks, but it can significantly mitigate harm to your business if one does occur, especially in the case of a ransomware attack.Misconception No. 2: One solution for all threatsSmall business owners are especially susceptible to believing that a single solution will defend against all possible threats. Security is better viewed as a managed process.Related: 10 Data-Security Measures You Can’t Do WithoutSimply having some legacy IT solutions in place shouldn’t let you develop a false sense of security and avoid asking important questions, including: Are we addressing vulnerabilities through security patching? Are we getting regular reports of that activity so that, in the event of a breach, it’s documented and we can respond effectively to an audit? Is our firewall being actively managed?You need to have a managed security system in place, one that includes regular reports on security measures, potential threats and updates. If you need more information, conduct some research on third-party managed security service providers, which can offer on-premise and remote solutions depending on your needs.Misconception No. 3: Cybersecurity training is for the IT guys.Data security isn’t just IT’s responsibility — it needs to be a priority for all employees. Your entire network can be compromised if, for instance, just one employee falls victim to a phishing email.The threat landscape is constantly changing. Implementing an employee-training program and being able to demonstrate that security should be a priority for all employees and is becoming increasingly important. Invest in regular training sessions and implement policies to reinforce the information shared. Misconception No. 4: The price isn’t right.Small business owners often look at security solutions and say, “That sounds expensive.” In reality, the cost of these services is far from prohibitive, and the services can scale as businesses and their needs grow.What’s more, forgoing security solutions means you risk the much higher price tag that accompanies a breach. Reports from Kaspersky Lab indicate that small businesses spend an average $38,000 recovering from just one data breach.Before making an investment, then, conduct a thorough assessment of your current security measures. A security audit will give you a good idea of where you stand and make you aware of any serious vulnerability. Related: 4 Strategies Small Businesses Can Use To Avoid a Data BreachLike any unfortunate event, data breaches can happen to any business — not just those with big names. The FTC ruling in LabMD demonstrates how the government is placing more and more liability responsibility on business owners to protect their client data.If yours is a small business, just claiming “I didn’t know” will no longer suffice when a data breach does occur. No matter what the size or industry of your business, make data security a top priority. 6 min read February 20, 2017 Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goalslast_img read more
