Coral reefs in Florida Keys hit hard this hurricane season, but there are signs of recovery

Coral reefs in Florida Keys hit hard this hurricane season, but there are signs of recoveryOut on the water's surface, floating above the site of a coral nursery was the first sign of trouble: a tangled mass of line, buoys, lobster traps, and debris.  A coral restoration team from Florida's Mote Marine Laboratory was checking on its underwater nursery for the first time since Hurricane Irma brought 140-mph winds to the Keys, and things didn't look promising. The team of scientists grows coral, which is then planted out on reefs decimated by global warming and other human abuses. SEE ALSO: Before and after photos show Hurricane Irma's devastation in the Caribbean "Right off the bat we thought, 'Oh it's going to be completely destroyed," said Erich Bartels, a Mote staff scientist. While the infrastructure, including the PVC trees where corals hang like drying laundry, survived the storm, much of the vibrant coral within the 60-by-80 meter site did not. Whipped up sand and tangled fishing gear had harmed the delicate coral.

Under the sea, the depleted coral reefs are also worse for wear, along with the underwater nurseries conservationists are growing in hopes of replenishing the Keys' once healthy reefs. The reefs are vital for the Florida coastline because the calcium carbonate structures act as a buffer from powerful waves. They're also important for the economy, as the sea life the reefs support helps feed the state and reel in tourists.  Globally, restoring coral reefs is taking on new urgency as more frequent and severe coral bleaching events kill reefs that are less tolerant of unusually high water temperatures.  "We can only begin to imagine how much more severely Irma would have damaged the Florida Keys without our coral reef shield," Mote's public relations manager Shelby Isaacson wrote in an email. Significant amounts of lobster trap lines got tangled in the Mote Marine Laboratory's coral trees, snagging other debris such as uprooted mangrove roots.Image: Erich Bartels/Mote Marine LaboratoryRestoration groups like Mote and the Coral Restoration Foundation (CRF), which had evacuated the area before landfall, are just starting to get back to work and do preliminary assessments of their nurseries and the reefs they support.  "It’s been tough to go back and see some of the reefs, because they’ve just been completely changed," said Jessica Levy, reef restoration program manager at the Coral Restoration Foundation (CRF). "The sites that we’ve seen are pretty barren, they've lost out-planted corals, they've lost natural corals, a lot of the soft corals. We’ve seen the ledge of the reef just collapse." A coral tree entangled in debris.Image: Erich Bartels/Mote Marine Laboratory The distinct line of bright, white reef was exposed during the hurricane.Image: Jessica Levy/Coral Restoration Foundation While the coral at the Mote nursery off Big Pine Key saw high mortality, two of CRF's underwater nurseries off Tavernier and Key Largo fared better. Still, CRF doesn't know the fate of two other production nurseries farther south because weather conditions have made it difficult to check.  Coral restoration groups have been working for years in Florida to combat decades of damage to the reefs, some of it, like coral bleaching, caused by climate change, some by overfishing, anchoring, polluting, and pathogens. Similar restoration projects are happening around the globe, and perhaps the most well-known is set along Australia's Great Barrier Reef, large swaths of which have been left bone-white and stricken with disease due to rising water temperatures. This was the first time both Mote and CRF's nurseries faced such a powerful storm. They had weathered tropical storms before, but nothing like Irma. The fact that their infrastructure survived, even if all the corals didn't, was heartening. "We were in the direct path of the eye, we were in what they call the 'dirty side.' It was about as big of a test that we could be given," Bartels said.  Mote scientists and volunteers planted 500 Staghorn Coral on Hope Reef on June 27, 2017, a few months before Irma hit.Image: Conor Goulding/Mote Marine LaboratoryAnother bright spot for Mote was its Summerland Key land-based nursery and gene bank, which opened this year and was built to resist Category 5 storms. The Elizabeth Moore International Center for Coral Reef Research & Restoration protected 30,000 coral fragments from the storm.  The coral living in shallow, long water tanks called raceways outside the facility were brought indoors just before Irma. Generators helped control the temperatures so the coral did not get exposed to hot water that could cause coral bleaching. While equipment left outside got beat up, the building — and coral sheltered inside — survived.

Both projects may be delayed a bit due to the hurricane, but the organizations are still optimistic about accomplishing their goals.  "I think at this point this work is needed now more than ever because we’ve seen what storms like this can do," Levy said. "This isn’t like we took a hit, we’re gonna stop. It's we took a hit, and we’re gonna keep going." Both Mote and Coral Restoration Foundation are fundraising to rebuild after Irma.  WATCH: 5-foot robotic snake is designed to find the source of pollution in contaminated water  



Transgender fish filmed changing sex for BBC’s Blue Planet II

Transgender fish filmed changing sex for BBC’s Blue Planet IIMating is never easy when you have an unsightly bulbous appendage protruding from your head. But the male Asian Sheepshead Wrasse has even greater problems to contend with. The female wrasse is endowed with the extraordinary ability to unexpectedly switch gender, a change which not only scuppers any burgeoning relationship with the male but also creates another headache for him - a new love rival. The gender-bending ability of the wrasse has been captured in detail for the first time for BBC Blue Planet II which airs on Sunday. The female kobudai (left) becomes even bigger than the male after transforming  Credit:  Tony Wu Scientists believe the female wrasse makes the switch because she can pass on more genes as a male, although it is unclear why some change while others remain female. It is just one of dozens of filming and scientific firsts captured over four years by the production team who also recorded huge flying fish which snatch birds from the sky, boiling seas, and  armour clad octopuses. A giant trevally leaps from the water to catch a tern in flight  Credit: BBC  Sir David Attenborough, who narrates the new series, said he was most impressed with new footage showing the efforts of the male anemone fish. “There have been a lot of really important scientific discoveries,” he told The Telegraph. “There’s a little anemone fish off the reef living in the sand that is surrounded by dangers but it finds refuge in the tentacles of an anemone, because it alone is immune to their poison. “But the female has to lay eggs, and she can’t do that on the soft tentacles of an anemone. So the little male goes around trying to find something where she could lay safely. “He finds an empty coconut shell, but the trouble is it’s miles away from the safety of the anemone. So he decides he’s going pull the thing all the way back. So he struggles with it, and the triumph on his little face when he does.” Filming The new series comes sixteen years after the original Blue Planet aired, and filmmakers have taken advantage of the latest marine science and cutting-edge technology to mount 125 expeditions across 39 countries, and spent more than 6,000 hours diving. The crews managed to film animal behaviour that until now has been rejected as just sailors myths. Mark Brownlow, Series Producer, said: “What’s exciting is we are working with scientists and we are helping them further their science. “Often the logistics is too massive for them to independently launch their own expedition but by collaborating we work together. “A really good example is the common octopus near Cape Town and when this octopus feels threatened it picks up stones, and shells on the seabed and wraps them around itself and it seems to be a protective coat. “Not only does it camouflage but it actually seems to be using the shells as a shield and we filmed that for the first time.” Blue Planet II : The Prequel 05:06 The team said the programmes were the most authentic ever, after the BBC Natural History Unit has faced criticism in the past for filming footage in zoos rather than in the natural world. Sir David said: “To say that we are distorting natural history would be absurd. However we wouldn’t do that now, I don’t think, because we are being very very meticulous to be correct and not in anyway misleading. “We do our best to be as honest as we can, and the Natural History Unit is extremely careful about constructing stories from too many sources.” False Killer Whales travelling with a pod of oceanic Bottlenose dolphins off the coast of the North Island, New Zealand Credit: Richard Robinson BBC  James Honeybourne, Executive Producer, added: It’s very important to us that we are true to nature. “We are very honest about all the techniques we use to create that, to tell as story. If you film something that’s microscopic you have to put added light on it, that’s just the simple laws of physics. “We don’t want to point that out in every episode you don’t want to break the spell, but we want to be upfront about that.” Blue Planet II starts Sunday 29 October 8pm on BBC One.

Stephen Hawking makes one of his most famous research papers available online

Stephen Hawking makes one of his most famous research papers available onlineMore than 50 years ago, Stephen Hawking wrote his doctoral thesis on how universes expand.  On Monday morning (GMT), that research became available for anyone to read through a digital library maintained by the University of Cambridge.  SEE ALSO: Researchers watched as gold was made millions of light-years from Earth “By making my PhD thesis Open Access, I hope to inspire people around the world to look up at the stars and not down at their feet; to wonder about our place in the universe and to try and make sense of the cosmos," Hawking said in a statement.   Hawking's 1966 thesis, " Properties of expanding universes," is the most requested item in the University of Cambridge's open access repository. The catalogue record gets hundreds of views per month, according to the the university. In recent months, hundreds of readers have made requests to download the entire thesis.  Hawking gave his permission to make the document available, and Cambridge officials hope his decision prompts current students to provide the same public access to their work and encourage its former academics to do the same. (The university has been home to 98 Nobel Prize recipients.) The historic Cambridge University Library maintains the physical papers of scientists like Isaac Newton and Charles Darwin and has made their research data available online.  "Anyone, anywhere in the world should have free, unhindered access to not just my research, but to the research of every great and enquiring mind across the spectrum of human understanding," Hawking said.  WATCH: Astronauts finally brought a fidget spinner to space

The Oceanic Pole of Inaccessibility: Where Spacecraft Go To Die

dryriver writes: Whether you launch a satellite into space or an entire space station like the Russian Mir, the Chinese Tiangong-1 or the International Space Station, what goes up must eventually come down -- re-enter earth's atmosphere. The greater the mass of what is in space -- Mir weighed 120 tons, the ISS weighs 450 tons and will be decommissioned in a decade -- the greater the likelihood that larger parts will not burn up completely during re-entry and crash to earth at high velocity. So there is a need for a place on earth where things falling back from space are least likely to cause damage or human casualties. The Oceanic Pole Of Inaccessibility is one of two such places. The place furthest away from land -- it lies in the South Pacific some 2,700km (1,680 miles) south of the Pitcairn Islands -- somewhere in the no-man's land, or rather no-man's-sea, between Australia, New Zealand and South America, has become a favorite crash site for returning space equipment. "Scattered over an area of approximately 1,500 sq km (580 sq miles) on the ocean floor of this region is a graveyard of satellites. At last count there were more than 260 of them, mostly Russian," reports the BBC. "The wreckage of the Space Station Mir also lies there... Many times a year the supply module that goes to the International Space Station burns up in this region incinerating the station's waste." The International Space Station will also be carefully brought down in this region when its mission ends. No one is in any danger because of this controlled re-entry into our atmosphere. The region is not fished because oceanic currents avoid the area and do not bring nutrients to it, making marine life scarce.

Bill Gates Tries A(nother) Billion-Dollar Plan To Reform Education

theodp shared this article from the Washington Post: Bill Gates has a(nother) plan for K-12 public education. The others didn't go so well, but the man, if anything, is persistent. Gates announced Thursday that the Bill & Melinda Gates Foundation would spend more than $1.7 billion over the next five years to pay for new initiatives in public education, with all but 15 percent of it going to traditional public school districts and the rest to charter schools... He said most of the new money -- about 60 percent -- will be used to develop new curriculums and "networks of schools" that work together to identify local problems and solutions, using data to drive "continuous improvement." He said that over the next several years, about 30 such networks would be supported, though he didn't describe exactly what they are... Though there wasn't a lot of detail on exactly how the money would be spent, Gates, a believer in using big data to solve problems, repeatedly said foundation grants given to schools as part of this new effort would be driven by data. "Each [school] network will be backed by a team of education experts skilled in continuous improvement, coaching and data collection and analysis," he said, an emphasis that is bound to worry critics already concerned about the amount of student data already collected and the way it is used for high-stakes decisions. In 2014, a $100 million student data collection project funded by the Gates foundation collapsed amid criticism that it couldn't adequately protect information collected on children. "In his speech, Gates said that education philanthropy was difficult, in part because it is easy to 'fool yourself' about what works and whether it can be easily scaled," according to the article. It also argues that big spending on education by Gates and others "has raised questions about whether American democracy is well-served by wealthy people pouring so much money into pet education projects -- regardless of whether they are grounded in research -- that public policy and funding follow." By 2011 the Gates' foundation had already spent $5 billion on education projects -- and admitted that "it hasn't led to significant improvements."

Silicon Valley 'Divided Society and Made Everyone Raging Mad', Argues Newsweek

"Anyone who is pissed off can now automatically find other people that are similarly pissed off," argues author Jamie Bartlett, in a new essay shared by Slashdot reader schwit1 which calls the internet "a bottomless well of available grievance." Here's an excerpt from Newsweek: Silicon Valley's utopians genuinely but mistakenly believe that more information and connection makes us more analytical and informed. But when faced with quinzigabytes of data, the human tendency is to simplify things. Information overload forces us to rely on simple algorithms to make sense of the overwhelming noise. This is why, just like the advertising industry that increasingly drives it, the internet is fundamentally an emotional medium that plays to our base instinct to reduce problems and take sides, whether like or don't like, my guy/not my guy, or simply good versus evil. It is no longer enough to disagree with someone, they must also be evil or stupid... Nothing holds a tribe together like a dangerous enemy. That is the essence of identity politics gone bad: a universe of unbridgeable opinion between opposing tribes, whose differences are always highlighted, exaggerated, retweeted and shared. In the end, this leads us to ever more distinct and fragmented identities, all of us armed with solid data, righteous anger, a gutful of anger and a digital network of likeminded people. This is not total connectivity; it is total division.

Google Says It Hasn't Promised To Help News Sites By Sharing Money and User Data

UPDATE (2:53 PST): Google say it hasn't lined up any deals to share revenue and user data with online news sites, calling Sunday news reports "totally wrong." "We have not reached any conclusions on the revenue side," Google spokeswoman Maggie Shiels told CNET. "We haven't reached any conclusions [regarding] subscriptions and need to speak to publishers." An anonymous reader shared the text of CNET's original report: The web giant is planning to share a chunk of its revenue with publishers, the Financial Times reported Sunday. Google's plan is to mate its treasure trove of personal data with machine learning algorithms to help news publications grow their subscriber base, the newspaper reported... The deal Google is offering to news publishers will reportedly be similar to the arrangement Google has with traditional advertisers through its AdSense business. "We want to have a healthy ecosystem where we'll benefit both as a society and with our business," Richard Gringas, Google's head of news, told the FT. Financial Times claimed that Google had promised that the revenue sharing "will be very, very generous," while TechCrunch had reported that Google would also be claiming "a 30% finder's fee" for every new subscriber.

30-Year-Old Operating System 'PC-MOS/386' Finally Open Sourced

PC-MOS/386 "was a multi-user, computer multitasking operating system...announced at COMDEX in November 1986," remembers Wikipedia, saying it runs many MS-DOS titles (though it's optimized for the Intel 80386 processor). Today Slashdot user Roeland Jansen writes: After some tracking, racing and other stuff...PC-MOS/386 v5.01 is open source under GPLv3. Back in May he'd posted to a virtualization site that "I still have the source tapes. I want(ed) to make it GPL and while I got an OK on it, I haven't had time nor managed to get it legalized. E.g. lift the NDA and be able to publish." 1987 magazine ads described it as "the gateway to the latest technology...and your networking future," and 30 years later its release on GitHub includes sources and executables. "In concert with Gary Robertson and Rod Roark it has been decided to place all under GPL v3."

Could Cryptocurrency Mining Kill Online Advertising?

"Could it turn out users actually prefer to trade a little CPU time to website owners in favor of them not showing ads?" writes phonewebcam, a long-time Slashdot reader. Slashdot covered the downside [of in-browser cryptocurrency mining] recently, with even [Portuguese professional sportsballer] Cristiano Ronaldo's official site falling victim, but that may not be the full story. This could be an ideal win-win situation, except for one huge downside -- the current gang of online advertisers. By "current gang of online advertisers," he means Google, according to a longer essay at LinkedIn: Naturally, the world's largest ad broker, which runs the world most popular browser (desktop and mobile) is keen to see how this plays out, and is also uniquely placed to be able to heavily influence it, too... As it happens, Chrome users can already do something about it via extensions, for example AntiMiner... If cryptocurrencies have a future - and that's a big if (look at China's Bitcoin ban) - it could well turn out that their role just took an unexpected turn.

Tesla Plans Factory In China, Discounts Insurance For Self-Driving US Cars

Business Insider reports: Tesla has created a customized insurance package, InsureMyTesla, that is cheaper than traditional plans because it factors in the vehicles' Autopilot safety features and maintenance costs. InsureMyTesla has been available in 20 countries, but Tesla just recently partnered with Liberty Mutual to make the plan available in the U.S. InsureMyTesla shows how the insurance industry is bound for disruption as cars get safer with self-driving tech. Electrek reports: There have been several false alarms over the past few years about Tesla building a factory in China. Earlier this year, Tesla finally confirmed working with the Shanghai government to establish a manufacturing facility in the region and promised an announcement by the end of the year. Now the Wall Street Journal reports that they have come to an agreement with the local authorities on a "wholly owned" factory in the region... China is already the biggest market for electric vehicles, or any vehicles for that matter, and Tesla profited from the demand by tripling its sales to over $1 billion in the country in 2016. Tesla continues to have strong sales in the country this year, where it leads foreign electric car sales with no close second.

Security Upgraded For NetBSD-amd64 with Kernel ASLR Support

24 years after its release, NetBSD is getting a security upgrade -- specifically, Address Space Layout Randomization (ASLR). An anonymous reader writes: Support for Kernel ASLR was added on NetBSD-amd64 a few weeks ago. KASLR basically randomizes the address of the kernel, and makes it harder to exploit several classes of vulnerabilities [including privilege escalations and remote code execution]. It is still a work-in-progress, but it's already fully functional, and can be used following the instructions on this post from the NetBSD blog. It will be available starting from NetBSD 9, but may be backported to NetBSD 8 once it is stabilized. NetBSD says they're the first BSD system to support ASLR.

Canadian Government Teams With Facebook To Protect Election Integrity

An anonymous reader quotes Motherboard: There are nearly as many Canadians who use Facebook daily as there are people in this country who are registered to vote -- which is why the federal government is working with Facebook to protect its next federal election... Facebook is now facing perhaps its biggest test as it looks to curb foreign electoral interference and the rampant disinformation on its platform, both of which undermine the nature of democracy. Facebook Canada's election integrity project includes a partnership with a local digital news media literacy organization MediaSmarts, as well as a "cyberhygiene guide" that highlights particular vulnerabilities such as phishing and page-admin authentication. Facebook also has a crisis email line to help politicians and parties with hacking concerns... Kevin Chan, Facebook Canada's head of public policy, said the social media company is working on preventing bad actors from interfering with the democratic process. "At Facebook we take our responsibilities seriously," Chan said. "We don't want anyone to use our tools to undermine democracy." At the launch of "the Canadian Election Integrity Initiative," Canada's Minister of Democratic Institutions argued that social media sites "must begin to view themselves as actors in shaping the democratic discourse." The article points out Facebook "has promised to hire thousands of workers globally to help review flagged and suspicious content, as well as use machine learning to identify suspicious patterns of behavior on its platform."

With Rising Database Breaches, Two-Factor Authentication Also At Risk

Two-factor authentication "protects from an attacker listening in right now," writes Slashdot reader szczys, "but in many case a database breach will negate the protections of two-factor." Hackaday reports: To fake an app-based 2FA query, someone has to know your TOTP password. That's all, and that's relatively easy. And in the event that the TOTP-key database gets compromised, the bad hackers will know everyone's TOTP keys. How did this come to pass? In the old days, there was a physical dongle made by RSA that generated pseudorandom numbers in hardware. The secret key was stored in the dongle's flash memory, and the device was shipped with it installed. This was pretty plausibly "something you had" even though it was based on a secret number embedded in silicon. (More like "something you don't know?") The app authenticators are doing something very similar, even though it's all on your computer and the secret is stored somewhere on your hard drive or in your cell phone. The ease of finding this secret pushes it across the plausibility border into "something I know", at least for me. The original submission calls two-factor authentication "an enhancement to password security, but good password practices are far and away still the most important of security protocols." (Meaning complex and frequently-changed passwords.)

A 14-Year-Old Asks: When Should I Get a VPN?

"One of my students sent me this letter," writes Slashdot reader Hasaf. "I have a good idea how I will answer, but I wanted to put it before the Slashdot community." The letter reads: Right now I am 14 years old, I was wondering when I should get a VPN... I was thinking about getting the yearly deal. But right now I really have no need for a VPN at the moment. I was thinking of getting a VPN when I'm in 11th grade or maybe in college. What do you think? Of course, the larger question is what factors go into deciding whether your need to be using a VPN. So leave your best answers in the comments. When should you get your first VPN?

Microsoft Chastises Google Over Chrome Security

An anonymous reader quotes PCMag: In a Wednesday blog post, Redmond examined Google's browser security and took the opportunity to throw some shade at Chrome's security philosophy, while also touting the benefits of its own Edge browser. The post, written by Microsoft security team member Jordan Rabet, noted that Google's Chrome browser uses "sandboxing" and isolation techniques designed to contain any malicious code. Nevertheless, Microsoft still managed to find a security hole in Chrome that could be used to execute malicious code on the browser. The bug involved a Javascript engine in Chrome. Microsoft notified Google about the problem, which was patched last month. The company even received a $7,500 reward for finding the flaw. However, Microsoft made sure to point out that its own Edge browser was protected from the same kind of security threat. It also criticized Google for the way it handled the patching process. Prior to the patch's official rollout, the source code for the fix was made public on GitHub, a software collaboration site that hosts computer code. That meant attentive hackers could have learned about the vulnerability before the patch was pushed out to customers, Microsoft claimed. "In this specific case, the stable channel of Chrome remained vulnerable for nearly a month," the blog post said. "That is more than enough time for an attacker to exploit it." In the past Google has also disclosed vulnerabilities found in Microsoft products -- including Edge.

For Under $1,000, Mobile Ads Can Track Your Location

"Researchers were able to use GPS data from an ad network to track a user to their actual location, and trace movements through town," writes phantomfive. Mashable reports: The idea is straightforward: Associate a series of ads with a specific individual as well as predetermined GPS coordinates. When those ads are served to a smartphone app, you know where that individual has been... It's a surprisingly simple technique, and the researchers say you can pull it off for "$1,000 or less." The relatively low cost means that digitally tracking a target in this manner isn't just for corporations, governments, or criminal enterprises. Rather, the stalker next door can have a go at it as well... Refusing to click on the popups isn't enough, as the person being surveilled doesn't need to do so for this to work -- simply being served the advertisements is all it takes. It's "an industry-wide issue," according to the researchers, while Mashable labels it "digital surveillance, made available to any and all with money on hand, brought to the masses by your friendly neighborhood Silicon Valley disrupters."

US Government Warns Of 'Ongoing' Hacks Targeting Nuclear and Power Industries

An anonymous reader quotes Reuters: The U.S government issued a rare public warning that sophisticated hackers are targeting energy and industrial firms, the latest sign that cyber attacks present an increasing threat to the power industry and other public infrastructure. The Department of Homeland Security and Federal Bureau of Investigation warned in a report distributed by email late on Friday that the nuclear, energy, aviation, water and critical manufacturing industries have been targeted along with government entities in attacks dating back to at least May. The agencies warned that hackers had succeeded in compromising some targeted networks, but did not identify specific victims or describe any cases of sabotage. The objective of the attackers is to compromise organizational networks with malicious emails and tainted websites to obtain credentials for accessing computer networks of their targets, the report said. According to the report, the Department of Homeland Security "has confidence that this campaign is still ongoing and threat actors are actively pursuing their objectives over a long-term campaign."

NYT Op-Ed Argues Amazon 'Took Seattle's Soul'

New York Times columnist Timothy Egan was part of the paper's Pulitzer Prize-winning team in 2001. Now he's written an op-ed arguing Amazon "took Seattle's soul." An anonymous reader writes: Since Amazon arrived "we've been overwhelmed by a future we never had any say over," Egan writes, with a message for cities competing to be the site of Amazon's next headquarters. Amazon now owns as much office space as Seattle's next 40 biggest employers combined, according to an analysis by the Seattle Times, "a mind-boggling 19 percent of all prime office space in the city, the most for any employer in a major U.S. city...more than twice as large as any other company in any other big U.S. city." Egan notes Amazon is offering 50,000 high-paying jobs and $5 billion worth of investments, "a once-in-a-century, destiny-shaping event," but "You think you can shape Amazon? Not a chance. It will shape you... What comes with the title of being the fastest growing big city in the country, with having the nation's hottest real estate market, is that the city no longer works for some people. For many others, the pace of change, not to mention the traffic, has been disorienting... [M]edian home prices have doubled in five years, to $700,000. This is not a good thing in a place where teachers and cops used to be able to afford a house with a water view... As a Seattle native, I miss the old city, the lack of pretense, and dinner parties that didn't turn into discussions of real estate porn. Wages have risen faster in Amazon's Seattle than anywhere else in America, and while Amazon changed the city's character, it also poured $38 billion into the city's economy. (Besides Amazon's own 40,000 employees, it also attracted another 50,000 new jobs.) "To the next Amazon lottery winner I would say, enjoy the boom," Egan concludes, "but be careful what you wish for."
