Microsoft will release the latest edition of its famous Flight Simulator software for PC later this month with ultra lifelike graphics - but it will require a massive 150GB of free storage to install it. The software will make use of satellite maps from Bing as well as live readings from weather stations and airports around the world to create'the most realistic' version of the game ever developed. Users simply upload their desired destination and use the'realistic' training system to navigate the area – the simulator is set to be released for PC on August 18, Xbox shortly after and VR later this year. The simulator lets'pilots' sit in a realistic cockpit, allowing them to learn the ins and outs of a real airplane and travel from or to more than 40,000 real-world airports and visit sites between them. The latest version of the 38 year old software includes 37 thousand airports, 1.5 billion buildings and two trillion trees, mountains, roads and rivers. According to Microsoft it will include live traffic, real time weather and moving animals to reflect the fact Earth is a'living world'.

SCI COMMUN### Conservation A company seeking to build a controversial gold and copper mine in Alaska won a major victory on 24 July when the U.S. Army Corps of Engineers issued an environmental analysis saying the mine wouldn't endanger the world's most productive sockeye salmon fishery. The decision clears the way for the Corps to issue permits needed by promoters of the Pebble Mine, located at the headwaters of two major watersheds that form part of the Bristol Bay salmon runs, just north of the Aleutian Islands. Environmental and Native Alaskan groups and some salmon scientists blasted the new study, saying it understated risks by focusing on the mine's small, initial footprint over 20 years of mining rather than its potential impacts if it expands to become one of the world's largest gold and copper mines, as its promoters hope. Mine backers have said such an expansion would get a closer environmental review later if they pursue it. Scientists have raised concerns that even the smaller mine could have wide impacts, because the resilience of the salmon runs hinges on access to a wide variety of spawning habitats. Environmental groups have vowed to file lawsuits to block the project. 90% —Accuracy of a new artificial intelligence system trained to identify individual weaver birds, which human birders generally cannot tell apart unless they are tagged ( Methods in Ecology and Evolution ). ### Planetary science China's first independent mission to Mars blasted off from the Xichang Satellite Launch Center on 23 July. To arrive in February 2021, Tianwen-1, a “quest for heavenly truth,” comprises an orbiter, lander, and rover. Only the United States and the Soviet Union have successfully landed on Mars. Instruments on the three Tianwen-1 craft will study the planet's magnetic field and atmosphere, map its surface, and characterize its geology. Tianwen-1 is the second in a trio of fresh martian missions: The United Arab Emirates launched its Hope orbiter on 19 July, and NASA planned to launch its Perseverance rover as early as 30 July, after Science went to press. ### Funding A bill in France would increase research spending over the next 10 years and add tenure-track faculty positions, a novelty in France. But critics say the plan's increases would be too small and slow. By 2030, the annual public research budget would rise by about one-third, to €20 billion, toward a goal of lifting overall R&D spending from 2.2% of gross domestic product to 3%. The National Research Agency, which funds researchers through competitive calls, would get €1 billion more over 7 years, reaching about €1.7 billion in 2027, to help raise its grant success rates from 16% to a target of 30%. The new, nonpermanent tenure-track positions would complement the permanent entry-level research positions traditionally offered by the French system, but critics fear the growth may lead to a decline in the permanent ones. Parliament is expected to approve the bill. ### Drug trials A monoclonal antibody given to babies has strongly protected them from severe disease caused by respiratory syncytial virus (RSV), a leading cause of infant death. As reported this week in The New England Journal of Medicine , a placebo-controlled study of nearly 1500 babies born preterm—who are at higher risk of severe symptoms of RSV—in 23 countries found that a single injection of the antibody before RSV season starts in the fall led to 78.4% fewer hospitalizations for lower respiratory infections associated with the disease. The antibody, being developed by AstraZeneca and Sanofi Pasteur, could replace one now on the market that is rarely used. (It is recommended only for infants at highest risk, requires five shots, and is very expensive.) The companies plan to seek regulatory approval of the new prophylaxis if larger studies now underway in preterm and full-term infants confirm that it is safe and effective. ### Graduate studies The American Astronomical Society last week launched the Astronomy Genealogy Project, which maps 5000 astronomers to their academic “descendants”—the 28,000 doctorate recipients they supervised. The discipline's family tree, at astrogen.aas.org, stretches back to 1766, but half of the listed doctorates were awarded since 2002. Organizers hope the data will help historians and sociologists of science analyze patterns across countries, universities, and subfields. U.S. universities awarded slightly more than half of the doctorates listed, and about two-thirds of the theses are online. ### Climate Environmental groups last week denounced as weak a plan announced by the U.S. Environmental Protection Agency (EPA) to limit greenhouse gas emissions from aircraft. The new standard would match an existing one adopted in 2016 by a U.N. body, the International Civil Aviation Organization (ICAO), that required emissions cuts by 2028. But recently manufactured planes already meet the standard, and EPA conceded its new rule would not reduce overall airplane emissions. Manufacturers have supported such a U.S. regulation to help them meet ICAO certification requirements. IACO has predicted that even under its standard, airplane emissions will grow by at least 3% a year globally. U.S. aviation accounts for 3% of the country's greenhouse gas emissions. ### Extreme life Bacteria from seafloor sediments buried 101 million years ago have been grown in the lab, raising the possibility they are as old as their muddy home. They had somehow survived in an area of the Pacific Ocean almost devoid of organic matter or other nutrients most bacteria need, although the sediments recovered do contain oxygen, the researchers report in Nature Communications . The finding pushes back the documented age of bacteria living in marine sediment from 15 million years and provides new insights on the limits of life under extreme conditions. A team led by researchers from the Japan Agency for Marine-Earth Science and Technology harvested the microbes from core samples drilled up to 5700 meters below sea level and took precautions against contaminating them with modern bacteria. The group argues the microbes likely didn't have enough food to keep replicating, and instead may have survived for eons without dividing by repairing age-related cellular damage. The microbes identified are known members of more than eight bacterial groups, many of which are commonly found elsewhere on Earth. ### Biotechnology Scientists announced last week that they used CRISPR gene editing to modify a cow embryo so that the resulting calf, named Cosmo, should produce more offspring bearing male traits. Bulls are 15% more efficient than cows at converting feed into weight gain, so the new method may allow cattle farmers to raise fewer cattle, benefiting the environment, say the researchers at the University of California, Davis. The researchers inserted a gene called SRY , which initiates male development and is normally found on the male sex chromosome, into an embryo's chromosome 17. Next, the researchers plan to determine whether Cosmo's offspring that inherit the SRY gene look and grow like males. Fifty percent of the calf's progeny will naturally be male; another 25% will be genetically female but will carry the SRY gene. ### Conservation Florida's governor this month signed a bill to establish a 162,000-hectare marine sanctuary in the Gulf of Mexico and protect one of the state's last remaining stretches of seagrass. Florida's coast boasts the most continuous expanse of seagrass beds in the United States, but these diverse habitats, home to blue crabs and manatees, have been damaged by nutrient-driven algal blooms and boat propellers. Authorities plan to create a management plan for the new Nature Coast Aquatic Preserve to balance protection with ecotourism, boating, and fishing. ### A magic ride for science In 1984, artist Bruce Degen met writer Joanna Cole at a publisher's office in New York City to discuss creating a children's book about science. They went on to collaborate and publish 13 colorful, zany books in The Magic School Bus series, featuring the ebullient, intrepid teacher Ms. Frizzle (above, right), who takes her students on fantastic adventures into the ocean, across the Solar System, and through the human body, for example. Cole died on 12 July at age 75. But the series continues to teach young readers and their parents about the natural world. > Q: Did you expect to create such a legacy? > A: I was in art school doing very serious art, and I realized that, in my heart of hearts, I wanted to do children's books. In the beginning, it was darn hard work. Some book sketch dummies have five layers of rewrites and reillustrations. The first book was a one-book contract to see if this would work. [The reception] was like the world was waiting for somebody to make this happen. People say, “[As a child,] I [used to] read these books, now I read them to my kids!” I could never have imagined it. > Q: Does scientific accuracy get in the way of storytelling? > A: Frequently. You have to tell kids what is true, but you can't give them all the truth—it's too much. For example, the evolution book goes from now [back] to the beginning of the Earth. I [initially] tried to show every era, year, and life form. It was too complicated. So it ended up as a nice, open spiral with a few representations of each era. > Q: Why use the format of adventures? > A: By following the story, it gave kids a mental filing system—they could retrieve and remember information because it was given to them in a memorable trip. ### Dispatches from the pandemic Read additional Science coverage of the pandemic at [sciencemag.org/tags/coronavirus][1]. #### U.S. vaccine efficacy trials begin The first large-scale efficacy trials of COVID-19 vaccines in the United States began last week. On 27 July, the National Institutes of Health, working with Moderna, announced the start of one that aims to recruit 30,000 people. Later that day, a partnership between Pfizer and BioNTech announced separately it was launching a similarly sized study at sites in the United States and elsewhere. Both the Moderna and the Pfizer/BioNTech vaccines contain messenger RNA that prompts cells to make a protein that studs the surface of the COVID-19 virus. If the vaccines work, this viral protein will safely teach the immune system how to battle the virus if a person later is exposed to it. Operation Warp Speed, the Trump administration's push to accelerate development of a COVID-19 vaccine, has committed nearly $3 billion to these two R&D projects, about half its total investment. Other efficacy trials of various COVID-19 vaccines have begun in Brazil, the United Arab Emirates, and the United Kingdom. Results are expected in late fall at the earliest. #### CDC slammed over school rules Guidance issued by the U.S. Centers for Disease Control and Prevention (CDC) last week for safely reopening schools downplays risks that teachers, other staff members, and students will spread or contract COVID-19, many public health specialists say. Provoking claims that CDC's advice had been politicized, the agency revised an earlier draft that President Donald Trump had panned as “very tough and expensive.” The nonbinding recommendations, released 23 July, emphasize the social and developmental benefits of in-person schooling and highlight that young children are at low risk for contracting the disease and transmitting the virus that causes it. The document also recommends against screening students for symptoms. Nevertheless, the Trump administration did advise communities with high infection rates to consider not beginning in-person classes. Large school districts, such as those in Atlanta, Houston, Los Angeles, and San Diego, have already announced that they will begin the 2020–21 school year with online instruction only. #### Anti-Fauci TV segment canceled Following heavy criticism from scientists and others, Sinclair Broadcast Corp. this week canceled plans for its chain of local TV stations to air a segment featuring widely challenged accusations that Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, intentionally created the virus responsible for COVID-19 and sent it to China. Fauci has helped lead the U.S. effort to control the pandemic despite tangling with President Donald Trump. The allegation came from Judy Mikovits, a virologist and antivaccine activist who appears in a documentary about the coronavirus that was also widely debunked as false and misleading (). The Sinclair segment, a new interview with Mikovits, was available online until the company pulled it for review on 25 July, after Media Matters reported its existence. Sinclair announced on 27 July that it would not air the segment on the nearly 200 TV stations it owns or operates in 89 U.S. markets—but not before one in Charleston, West Virginia, had broadcast it.

For a few seconds, it seems real. Then, on the horizon, the landscape gives way to rugged coastline, and, as the plane flies closer, we glimpse the rippling waves glinting in the evening sun. In real life, I have not seen the ocean for five months and, although I'm just sitting in my kitchen watching a virtual presentation of a video game, I feel a surge of emotion. When the latest instalment in Microsoft's decades-old Flight Simulator series was first shown at the E3 video game event last year, it drew gasps from the audience. Using two petabytes of geographic data culled from Bing Maps, together with cutting-edge, machine learning algorithms running on the company's Azure cloud computing network, the game presents a near-photorealistic depiction of the entire planet.

Washington – The United States and close ally Australia held high-level talks on China on Tuesday and agreed on the need to uphold a rules-based global order, but the Australian foreign minister stressed that Canberra's relationship with China was important and it had no intention of injuring it. U.S. Secretary of State Mike Pompeo and Defense Secretary Mark Esper held two days of talks in Washington with their Australian counterparts, Foreign Minister Marise Payne and Defense Minister Linda Reynolds, who had flown around the world for the meetings despite the COVID-19 pandemic and face two weeks of quarantine on their return. At a joint news conference, Pompeo praised Australia for standing up to pressure from China and said Washington and Canberra would continue to work together to reassert the rule of law in the South China Sea, where China has been pressing its claims. Payne said the United States and Australia shared a commitment to the rule of law and had reiterated their commitment to hold countries to account for breaches, such as China's erosion of freedoms in Hong Kong. She said the two sides had also agreed to form a working group to monitor and respond to harmful disinformation and would look at ways to expand cooperation on infectious diseases, including access to vaccines.

Washington – U.S. Secretary of State Mike Pompeo took fresh aim at China on Thursday and said Washington and its allies must use "more creative and assertive ways" to press the Chinese Communist Party to change its ways, calling it the "mission of our time." Speaking at the Nixon Library in former President Richard Nixon's birthplace in Yorba Linda, California, Pompeo said the late U.S. leader's worry about what he had done by opening the world to China's Communist Party in the 1970s had been prophetic. "President Nixon once said he feared he had created a'Frankenstein' by opening the world to the CCP," Pompeo said. Nixon, who died in 1994 and was president from 1969 to 1974 opened the way for the establishment of U.S. diplomatic relations with Communist China in 1979 through a series of contacts, including a visit to Beijing in 1972. In a major speech delivered after Washington's surprise order this week for China to close its Houston consulate, Pompeo repeated frequently leveled U.S. charges about Beijing's unfair trade practices, human rights abuses and efforts to infiltrate American society.

Our second annual list highlights promising, private, U.S.-based companies that are using artificial intelligence in meaningful business-oriented ways.

Through the pixel fuzz of a sputtering Zoom connection, it's hard to be sure if the eyes staring out from the laptop screen are human. Lars Buttler is a real person, but he is the CEO of AI Foundation, a company that makes fake ones: trainable, artificially intelligent agents that might one day take the place of a human personal assistant, a customer service representative, or you yourself (if you aspire to omnipresence or digital deathlessness). When Buttler appeared in a Zoom call last week, there was something strange about the light hitting his shaved head, and the stark white office behind him definitely wasn't part of the material world. His speech was awkward, with overlong pauses and canned jokes that fell on a silent audience, but video calls are like that, at least for now, while people adjust to working lives forced into the ether. His eyes seemed awake and alive in a way that the faces of the other participants in the Zoom call--venture capitalist, a tech founder, and an activist, all of them puppeted by artificial intelligence--were not.

In the late winter and spring of 2019, a group of Indigenous scholars met in Hawai'i to think through concepts around artificial intelligence (AI) and how they related to the Indigenous experience. Co-organized by Jason Edward Lewis, professor in the Department Design and Computation Arts, the multidisciplinary group included participants from Canada, the United States, Australia, New Zealand and the United Kingdom. Concordia graduate students Scott Benesiinaabandan (MFA Studio Arts) and Suzanne Kite (PhD INDI) as well as Concordia research associate Skawennati also participated. The first session in March largely consisted of brainstorm workshops about how and where Indigeneity intersects with AI. The second, in May, focused more on writing and laying the foundations of what would become the now-completed Indigenous Protocol and Artificial Intelligence Position Paper.

In this work, we study adaptive data-guided traffic planning and control using Reinforcement Learning (RL). We shift from the plain use of classic methods towards state-of-the-art in deep RL community. We embed several recent techniques in our algorithm that improve the original Deep Q-Networks (DQN) for discrete control and discuss the traffic-related interpretations that follow. We propose a novel DQN-based algorithm for Traffic Control (called TC-DQN+) as a tool for fast and more reliable traffic decision-making. We introduce a new form of reward function which is further discussed using illustrative examples with comparisons to traditional traffic control methods.

The cinematic depictions are pretty clear. From I, Robot to The Terminator series to The Matrix, humans, either wittingly or unwittingly, manage to clash with the machinery that had previously served them. It's a narrative that, like some of our best mythos, puts us at the center of the action and more often than not shows the supremacy of human ingenuity under pressure. Because it's Hollywood, and Hollywood specializes in fictions. Well, at least part of it is a fiction.
