Morgan Stanley plans to ban workers from its New York headquarters if they have not received a Covid-19 vaccine. The rule will apply to non-vaccinated guests and clients as well. From a report: According to a source close to the company, Morgan Stanley said in a memo to its employees in the New York metropolitan area that all staff working in buildings with a "large employee presence" are required to confirm their vaccination status by July 1. The source added that "vaccine attestation is on an honorary basis for employees, contingent workforce, clients and visitors." The company plans to expand the vaccination mandate to employees and guests in other Morgan Stanley locations in New York City and nearby Westchester starting July 12. "Operating within a fully vaccinated environment allows us to lift restrictions like the use of face coverings and the need to maintain physical distancing, returning to more normal office conditions," the source added.

For billions of years, Earth has been playing a cosmic game of hide-and-seek. New research published today in Nature posits that roughly 1,700 stars are in the right position to have spotted life on Earth as early as 5,000 years ago. From a report: These stars, within 100 parsecs (or about 326 light-years) of the sun, were found using data from NASA's Transiting Exoplanet Survey Satellite and the European Space Agency's Gaia mission. And with thousands of exoplanets already found orbiting other stars in our universe, could we have already seen life on other planets come and go? Might they have seen us? "The universe is dynamic," says Lisa Kaltenegger, director of the Carl Sagan Institute at Cornell, and lead author of the study. "Stars move, we move. First the Earth moves around the sun, but the sun moves around the center of our galaxy."

About 70% of exoplanets are found using the transit method: when a planet passes between a star and an observer, the star dims enough to confirm the presence of a previously unseen celestial body. Kaltenegger and coauthor Jackie Faherty of the American Museum of Natural History compiled a list of stars that either will see or already have seen Earth transit in their lifetimes. Of these, they found seven stars with orbiting exoplanets that could potentially be habitable. Statistically, one out of four stars has a planet that exists in the "Goldilocks zone" -- not too hot, not too cold, and just far away from a star to support life. But how do we determine whether faraway exoplanets meet these criteria? When transiting exoplanets block stellar light, part of that light filters through the atmosphere. Energy and light interact with the molecules and atoms of that planet, and by the time that light reaches an astronomer's telescope, scientists can determine whether it has interacted with chemicals like oxygen or methane. A combination of those two, Kaltenegger says, is the fingerprint for life.

Epic Systems' algorithm for identifying signs of sepsis, an often deadly complication from infections that can lead to organ failure, doesn't work as well as advertised, according to a new study published in JAMA Internal Medicine. The Verge reports: Epic says its alert system can correctly differentiate patients who do and don't have sepsis 76 percent of the time. The new study found it was only right 63 percent of the time. An Epic spokesperson disputed the findings in a statement to Stat News, saying that other research showed the algorithm was accurate. Sepsis is hard to spot early, but starting treatment as soon as possible can improve patients' chances of survival. The Epic system, and other automated warning tools like it, scan patient test results for signals that someone could be developing the condition. Around a quarter of US hospitals use Epic's electronic medical records, and hundreds of hospitals use its sepsis prediction tool, including the health center at the University of Michigan, where study author Karandeep Singh is an assistant professor.

The study examined data from nearly 40,000 hospitalizations at Michigan Medicine in 2018 and 2019. Patients developed sepsis in 2,552 of those hospitalizations. Epic's sepsis tool missed 1,709 of those cases, around two-thirds of which were still identified and treated quickly. It only identified 7 percent of sepsis cases that were missed by a physician. The analysis also found a high rate of false positives: when an alert went off for a patient, there was only a 12 percent chance that the patient actually would develop sepsis. Part of the problem, Singh told Stat News, seemed to be in the way the Epic algorithm was developed. It defined sepsis based on when a doctor would submit a bill for treatment, not necessarily when a patient first developed symptoms. That means it's catching cases where the doctor already thinks there's an issue. "It's essentially trying to predict what physicians are already doing," Singh said. It's also not the measure of sepsis that researchers would ordinarily use.

An anonymous reader quotes a report from Phys.Org: A team of researchers from the Max Planck Institute of Molecular Plant Physiology, the University of Naples Federico II, the Weizmann Institute of Science and the Porter School of the Environment and Earth Sciences has found that making food from air would be far more efficient than growing crops. In their paper published in Proceedings of the National Academy of Sciences, the group describes their analysis and comparison of the efficiency of growing crops (soybeans) and using a food-from-air technique. [...] To make their comparisons, the researchers used a food-from-air system that uses solar energy panels to make electricity, which is combined with carbon dioxide from the air to produce food for microbes grown in a bioreactor. The protein the microbes produce is then treated to remove nucleic acids and then dried to produce a powder suitable for consumption by humans and animals.

They compared the efficiency of the system with a 10-square-kilometer soybean field. Their analysis showed that growing food from air was 10 times as efficient as growing soybeans in the ground. Put another way, they suggested that a 10-square-kilometer piece of land in the Amazon used to grow soybeans could be converted to a one-square-kilometer piece of land for growing food from the air, with the other nine square kilometers turned back to wild forest growth. They also note that the protein produced using the food-from-air approach had twice the caloric value as most other crops such as corn, wheat and rice.

After six months of check-out and calibration in orbit, the Sentinel-6 Michael Freilich satellite will make its first two data streams available to the public on June 22. It launched from Vandenberg Air Force Base in California on Nov. 21, 2020, and is a U.S.-European collaboration to measure sea surface height and other key ocean features, such as ocean surface wind speed and wave height. Phys.Org reports: One of the sea surface height data streams that will be released is accurate to 2.3 inches (5.8 centimeters) and will be available within hours of when the instruments aboard Sentinel-6 Michael Freilich collect it. A second stream of data, accurate to 1.4 inches (3.5 centimeters), will be released two days after collection. The difference in when the products become available balances accuracy with delivery timeliness for tasks like forecasting the weather and helping to monitor the formation of hurricanes. More datasets, which will be accurate to about 1.2 inches (2.9 centimeters), are slated for distribution later this year and are intended for research activities and climate science including tracking global mean sea level rise.

The satellite, named after former NASA Earth Science Division Director Michael Freilich, collects its measurements for about 90% of the world's oceans. It is one of two satellites that compose the Copernicus Sentinel-6/Jason-CS (Continuity of Service) mission. The second satellite, Sentinel-6B, is slated for launch in 2025. Together, they are the latest in a series of spacecraft starting with TOPEX/Poseidon in 1992 and continuing with the Jason series of satellites that have been gathering precise ocean height measurements for nearly 30 years. Shortly after launch, Sentinel-6 Michael Freilich moved into position, trailing the current reference sea level satellite Jason-3 by 30 seconds. Scientists and engineers then spent time cross-calibrating the data collected by both satellites to ensure the continuity of measurements between the two. Once they have are assured of the data quality, Sentinel-6 Michael Freilich will then become the primary sea level satellite.

An anonymous reader quotes a report from The Guardian: From espresso to instant, coffee is part of the daily routine for millions. Now research suggests the brew could be linked to a lower chance of developing or dying from chronic liver disease. Chronic liver disease is a major health problem around the world. According to the British Liver Trust, liver disease is the third leading cause of premature death in the UK, with deaths having risen 400% since 1970. Writing in the journal BMC Public Health, Roderick and colleagues report how they analyzed data from 494,585 participants in the UK Biobank -- a project designed to help unpick the genetic and environmental factors associated with particular conditions. All participants were aged 40 to 69 when they signed up to the project, with 384,818 saying they were coffee drinkers at the outset compared with 109,767 who did not consume the beverage.

The team looked at the liver health of the participants over a median period of almost 11 years, finding 3,600 cases of chronic liver disease, with 301 deaths, and 1,839 cases of simple fatty liver disease. The analysis revealed that after taking into account factors such as body mass index, alcohol consumption, and smoking status, those who drank any amount of coffee, and of any sort, had a 20% lower risk of developing chronic liver disease or fatty liver disease (taken together) than those who did not consume the brew. The coffee drinkers also had a 49% lower risk of dying from chronic liver disease. The team said the magnitude of the effect increased with the amount of coffee consumed, up to about three to four cups a day, "beyond which further increases in consumption provided no additional benefit." A reduction in risk was also found when instant, decaffeinated and ground coffee were considered separately -- although the latter linked to the largest effect.

Venus might be hell, but don't call it a dead planet. Amid surface temperatures of up to 471C and surface pressures 100 times greater than those on Earth, new research suggests the planet might still be geologically active. That's encouraging news to people who think it could once have hosted life (or that it might still be able to). From a report: Earth's lithosphere (its crust and upper mantle) is made of "plates" that move around and crash into each other, resulting in mountains, deep ocean trenches, and volcanic and seismic activity. This tectonic activity also plays an important role in the carbon cycle, the processes in which carbon is released and reabsorbed in the ecosystem; by regulating the amount of carbon dioxide in the atmosphere, it has helped keep the planet cool and comfortable this whole time. Thus far, scientists have never observed anything similar on Venus. But we've never been able to rule it out, because it's hard to make scientific observations of the planet (its thick clouds obscure its surface, and any spacecraft we'd land there would most likely melt in a matter of hours). In the new findings, published in PNAS, scientists think they've finally spotted evidence of a new type of tectonic activity on Venus.

The team used observations made by the Magellan probe, which orbited Venus from 1990 to 1994 and mapped the surface using radar. The features it spotted have been analyzed before, but the new study uses a new computer model that can recognize surface deformations indicating large block structures in the lithosphere. These blocks, each about the size of Alaska, seem to have been sluggishly jostling against each other like broken pack ice on a pond or lake. This is quite different from the current type of plate tectonics on Earth. But if confirmed, it would nonetheless be evidence of heat currents and molten material in Venus's interior -- something that's never before been observed. The authors think parallels with Earth's geology during the Archean Eon (2.5 to 4 billion years ago) suggest that the "pack ice" patterns could be a transition from an earlier period of plate tectonics on Venus when the planet was more Earth-like.

The highly contagious delta variant is the fastest and fittest coronavirus strain yet, and it will "pick off" the most vulnerable people, especially in places with low Covid-19 vaccination rates, World Health Organization officials warned Monday. From a report: Delta, first identified in India, has the potential "to be more lethal because it's more efficient in the way it transmits between humans and it will eventually find those vulnerable individuals who will become severely ill have to be hospitalized and potentially die," Dr. Mike Ryan, executive director of the WHO's emergencies program, said during a news conference. Ryan said world leaders and public health officials can help defend the most vulnerable through the donation and distribution of Covid vaccines. "We can protect those vulnerable people, those frontline workers," Ryan said, "and the fact that we haven't, as Director-General (Tedros Adhanom Ghebreyesus) has said, again and again, is a catastrophic moral failure at a global level." The WHO said Friday that delta is becoming the dominant variant of the disease worldwide. The agency declared delta a "variant of concern" last month. A variant can be labeled as "of concern" if it has been shown to be more contagious, more deadly or more resistant to current vaccines and treatments, according to the health organization.

Wired published a long extract from Amit Katwala's book Quantum Computing: How It Works and How It Could Change the World — explaining how it's already being put to use to explore some of science's biggest secrets by simulating nature itelf: Some of the world's top scientists are engaged in a frantic race to find new battery technologies that can replace lithium-ion with something cleaner, cheaper and more plentiful. Quantum computers could be their secret weapon... Although we've known all the equations we need to simulate chemistry since the 1930s, we've never had the computing power available to do it...

In January 2020, researchers at IBM published an early glimpse of how quantum computers could be useful in the Noisy Intermediate-Scale Quantum Computing era. Working with the German car manufacturer Daimler on improving batteries for electric vehicles, they used a small-scale quantum computer to simulate the behaviour of three molecules containing lithium, which could be used in the next generation of lithium-sulphur batteries that promise to be more powerful and cheaper than today's power cells..
Some other examples:

• "Chemistry challenges just waiting for a quantum computer powerful and reliable enough to crack them range from the extraction of metals by catalysis through to carbon dioxide fixation, which could be used to capture emissions and slow climate change. But the one with the potential for the biggest impact might be fertiliser production... Some plants rely on bacteria which use an enzyme called nitrogenase to 'fix' nitrogen from the atmosphere and incorporate it into ammonia. Understanding how this enzyme works would be an important step towards...creating less energy-intensive synthetic fertilisers."

• "Solar panels are another area where quantum computers could help, by accelerating the search for new materials. This approach could also help to identify new materials for batteries, and superconductors that work at room temperature, which would drive advances in motors, magnets and perhaps even quantum computers themselves...."

• "Quantum computing could help scientists model complex interactions and processes in the body, enabling the discovery of new treatments for diseases such as Alzheimer's, or a quicker understanding of new diseases such as Covid-19. Artificial intelligence is already being used by companies such as DeepMind to gain insight into protein folding — a key facet of growth and disease — and quantum computers will accelerate this effort."

USA Today reports: Companies like Moderna and Pfizer's partner BioNTech, whose names are familiar from COVID-19 vaccines, are using mRNA to spur cancer patients' bodies to make vaccines that will — hopefully — prevent recurrences and treatments designed to fight off advanced tumors. If they prove effective, which won't be known for at least another year or two, they could be added to the arsenal of immune therapies designed to get the body to fight off its own tumors...

Over the last decade, pharmaceutical companies around the world have been developing new ways to train the body's immune system to fight off tumors, particularly melanoma. They had learned how to remove a brake installed by tumors, unleashing the warriors of the immune system. Ten years ago, only about 5% of people with advanced melanoma survived for five years. Now, nearly half make it that long. Trials of mRNA cancer vaccines aim to boost that number even higher by adding soldiers to the fight... Once a tumor has been largely removed through surgery, a vaccine can help generate new immune soldiers known as T cells... A computer algorithm analyzes the mutations distinct to the cancer cells, looking for ones that trigger the production of T cells, said Melissa J. Moore, Moderna's chief scientific officer, of platform research. So far, she said, Moderna, working with partner Merck, has tested these personalized vaccines in about 100 patients. They aim eventually to make a personalized mRNA vaccine within about 45 days after the patient's cancer surgery, during their recovery...

Mutated cancer cells have proteins on their surface that can be targeted by an mRNA vaccine. For a tumor that has, say, five common mutations, a patient could get a combination of five of these vaccines. On Friday, BioNTech announced it was launching a new trial for this approach, testing it in 120 melanoma patients Europe, the United Kingdom, Australia and the U.S. The new treatment, given in connection with an antibody from Regeneron, is aimed at four tumor-associated antigens. More than 90% of melanoma tumors contain at least one of the four.
The U.S. federal government now lists 29 studies underway or that will be soon investigating mRNA cancer vaccines, according to the article.

And Dr. Stephen Hahn, who had a career as an oncologist before running the Food and Drug Administration from 2019 until early this year, "said he's more optimistic this time because of how much researchers have learned about the role the immune system plays in cancer. 'That gives us an edge to maybe finally get to the place where we need to be.'"

The Hubble Space Telescope was launched into low-earth orbit in 1990 with an even older computer. Over the next 13 years it received upgrades and repairs from astronauts on five different visits from America's Space Shuttle.

But now in 2021, "NASA continues to work on resolving an issue with the payload computer on the Hubble Space Telescope," reports SciTechDaily — though "The telescope itself and science instruments remain in good health." The operations team will be running tests and collecting more information on the system to further isolate the problem. The science instruments will remain in a safe mode state until the issue is resolved...

The computer halted on Sunday, June 13. An attempt to restart the computer failed on Monday, June 14. Initial indications pointed to a degrading computer memory module as the source of the computer halt. When the operations team attempted to switch to a back-up memory module, however, the command to initiate the backup module failed to complete. Another attempt was conducted on both modules Thursday evening to obtain more diagnostic information while again trying to bring those memory modules online. However, those attempts were not successful.

For the next three months, three Chinese astronauts will live on a cylinder-shaped module measuring 16.6 metres by 4.2 metres (54 feet by 13.7 feet) while carrying out further construction work for China's orbiting space station.

It's the first time in five years China has sent humans into space, reports NBC News. : Shenzhou-12, or "Divine Vessel," is one of 11 planned missions to complete construction of China's 70-ton Tiangong or Harmony of the Heavens space station that is set to be up and running by next year... China has long been frozen out of the International Space Station, or ISS, a project launched 20 years ago that has served as the ultimate expression of post-Cold War reconciliation between Russia and the United States. American concerns over the Chinese space program's secrecy and connections to its military were largely responsible for that. But the aging ISS that hosted astronauts from the U.S., Russia and a number of other countries is set to be decommissioned after 2024. As broader U.S.-Russia relations deteriorate, Moscow has hinted that it may withdraw from ISS cooperation in 2025, meaning China could be the only country with a functioning space station.

Roscosmos, the Russian space agency, also signed an agreement in March with the Chinese National Space Administration to build a base on or around the Moon, which they will call the International Scientific Lunar Station.

"All the firsts that the U.S. and the USSR did in the Cold War, China is just ticking them off," said Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics. "Now they're at the point where they're starting to think, 'OK, we're not just copying the West anymore, we're going to start doing our own thing'. And that's going to be very interesting to watch."

The U.S. government spent more than $18 billion last year funding drugmakers to make a Covid vaccine, an effort that led to at least five highly effective shots in record time. Now it's pouring more than $3 billion on a neglected area of research: developing pills to fight the virus early in the course of infection, potentially saving many lives in the years to come. From a report: The new program, announced on Thursday by the Department of Health and Human Services, will speed up the clinical trials of a few promising drug candidates. If all goes well, some of those first pills could be ready by the end of the year. The Antiviral Program for Pandemics will also support research on entirely new drugs -- not just for the coronavirus, but for viruses that could cause future pandemics. A number of other viruses, including influenza, H.I.V. and hepatitis C, can be treated with a simple pill. But despite more than a year of research, no such pill exists to treat someone with a coronavirus infection before it wreaks havoc. Operation Warp Speed, the Trump administration's program for accelerating Covid-19 research, invested far more money in the development of vaccines than of treatments, a gap that the new program will try to fill.

Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases and a key backer of the program, said he looked forward to a time when Covid-19 patients could pick up antiviral pills from a pharmacy as soon as they tested positive for the coronavirus or develop Covid-19 symptoms. "I wake up in the morning, I don't feel very well, my sense of smell and taste go away, I get a sore throat," Dr. Fauci said in an interview. "I call up my doctor and I say, 'I have Covid and I need a prescription.'" Dr. Fauci's support for research on antiviral pills stems from his own experience fighting AIDS three decades ago. In the 1990s, his institute conducted research that led to some of the first antiviral pills for H.I.V., "protease inhibitors" that block an essential virus protein and can keep the virus at bay for a lifetime.

Immortality and everlasting youth are the stuff of myths, according to new research which may finally end the eternal debate about whether we can live for ever. From a report: Backed by governments, business, academics and investors in an industry worth $110bn -- and estimated to be worth $610bn by 2025 -- scientists have spent decades attempting to harness the power of genomics and artificial intelligence to find a way to prevent or even reverse ageing. But an unprecedented study has now confirmed that we probably cannot slow the rate at which we get older because of biological constraints. The study, by an international collaboration of scientists from 14 countries and including experts from the University of Oxford, set out to test the "invariant rate of ageing" hypothesis, which says that a species has a relatively fixed rate of ageing from adulthood.

"Our findings support the theory that, rather than slowing down death, more people are living much longer due to a reduction in mortality at younger ages," said Jose Manuel Aburto from Oxford's Leverhulme Centre for Demographic Science, who analysed age-specific birth and death data spanning centuries and continents. "We compared birth and death data from humans and non-human primates and found this general pattern of mortality was the same in all of them," said Aburto. "This suggests that biological, rather than environmental factors, ultimately control longevity. The statistics confirmed, individuals live longer as health and living conditions improve which leads to increasing longevity across an entire population. Nevertheless, a steep rise in death rates, as years advance into old age, is clear to see in all species."

A new computer simulation shows that a technologically advanced civilization, even when using slow ships, can still colonize an entire galaxy in a modest amount of time. The finding presents a possible model for interstellar migration and a sharpened sense of where we might find alien intelligence. From a report: Space, we are told time and time again, is huge, and that's why we have yet to see signs of extraterrestrial intelligence. For sure, the distances between stars are vast, but it's important to remember that the universe is also very, very old. In fact, I'd go so far as to say that, in terms of extremes, the Milky Way galaxy is more ancient than it is huge, if that makes sense. It's for this reason that I tend to dismiss distances as a significant variable when discussing the Fermi Paradox -- the observation that we have yet to see any evidence for the existence of alien intelligence, even though we probably should have. New research published in The American Astronomical Society is bolstering my conviction.

The new paper, co-authored by Jason Wright, an astronomer and astrophysicist at Penn State, and Caleb Scharf, an astrobiologist at Columbia University, shows that even the most conservative estimates of civilizational expansion can still result in a galactic empire. A simulation produced by the team shows the process at work, as a lone technological civilization, living in a hypothetical Milky Way-like galaxy, begins the process of galactic expansion. Grey dots in the visualization represent unsettled stars, magenta spheres represent settled stars, and the white cubes are starships in transit. The computer code and the mathematical analysis for this was project were written at the University of Rochester by Jonathan Carroll-Nellenback. Astronomer Adam Frank from the University of Rochester also participated in the study.

California on Friday started offering residents a digital record of their coronavirus vaccinations that they can use to access businesses or events that require proof they got the shots. From a report: The state's public health and technology departments said the new tool allows Californians access to their COVID-19 vaccination records from the state's immunization registry and includes the same information as the paper cards issued by the Centers for Disease Control and Prevention. To access the information, Californians will enter into a state website their name, date of birth and email or phone associated with their vaccine records and they will be asked to create a four-digit PIN. The record will include a QR code that users can save to their mobile phones. With nearly 20 million people fully vaccinated in California and proof of vaccination already required in some circumstances such as travel, state health officials felt there would be demand for the tool, though it remains optional, said Dr. Erica Pan, the state's epidemiologist.

If someone created a flying machine capable of tracking you down by listening for your voice, you might be creeped out. But what if you were pinned under a pile of rubble after a natural disaster and first responders couldn't locate you? Maybe then a human-seeking drone wouldn't be such a terrible idea. From a report: That concept is the focus for engineers at Germany's Fraunhofer FKIE institute, who've built a drone prototype designed to find people by detecting human screams and listening for other signs of distress. One of the lead engineers, Macarena Varela, showcased their progress last week at an annual conference hosted by the Acoustic Society of America. While it's easy to imagine human-seeking drones in a sci-fi horror movie, Varela says the gadget would be ideal for post-disaster scenarios, such as earthquakes, hurricanes and wildfires. They could hover over an area that rescue crews have difficulty getting to and pinpoint where people may be trapped.

"[Drones] can cover a larger area in a shorter period of time than rescuers or trained dogs on the ground," Varela said. "If there's a collapsed building, it can alert and assist rescuers. It can go places they can't fly to or get to themselves." Unmanned aerial vehicles or drones are commonly used for search-and-rescue missions when disasters strike. Most often, they take aerial images of structural damage. Some have thermal imaging capabilities to scan for body heat, while larger drones can deliver medical supplies and other goods to people in isolated areas. But researchers are finding more novel uses for an extra set of eyes in the sky -- and noses. The University of Washington imagines drones that use smell to locate disaster survivors. The Aerospace Corporation is working on drones that can visually identify dogs and share their location with rescue teams. The University of Zurich developed a drone to change shape midflight to fit into oddly shaped crevices. Locating people using aerial acoustics presents its share of challenges. An auditory system would need to decipher between human cries and sounds that often happen in nature, such as animal calls and wind. It might also need to recognize patterns associated with kicking, clapping or other ways people try to get the attention of rescue teams.

The Earth is trapping nearly twice as much heat as it did in 2005, according to new research, described as an "unprecedented" increase amid the climate crisis. From a report: Scientists from NASA, the US space agency, and the National Oceanic and Atmospheric Administration (Noaa), reported in a new study that Earth's "energy imbalance approximately doubled" from 2005 to 2019. The increase was described as "alarming." "Energy imbalance" refers to the difference between how much of the Sun's "radiative energy" is absorbed by Earth's atmosphere and surface, compared to how much "thermal infrared radiationâ bounces back into space.

"A positive energy imbalance means the Earth system is gaining energy, causing the planet to heat up," NASA said in a statement about this study. Scientists determined there was an energy imbalance by comparing data from satellite sensors -- which track how much energy enters and exits Earth's system -- and data from ocean floats. This system of data-gathering floats, which stretches across the globe, allows for "an accurate estimate of the rate at which the world's oceans are heating up." Because about 90% of excess energy from an imbalance winds up in the ocean, the satellite sensors' data should correspond with temperature changes in oceans.

SpaceX successfully launched an advanced GPS satellite for the U.S. Space Force on Thursday (June 17), marking the 19th launch of the year here on the Space Coast. From a report: One of the company's two-stage Falcon 9 rockets blasted off from Space Launch Complex 40 at Cape Canaveral Air Force Station here at 12:09 p.m. EST (1409 GMT), carrying the GPS III SV05 navigation satellite to orbit. Nine minutes later, the rocket's first stage touched down on the deck of "Just Read the Instructions," one of SpaceX's two drone ships. "What a beautiful view of the first stage landing," Youmei Zhou, a SpaceX propulsion engineer, said during the company's live launch commentary.

The GPS III SV05 satellite mission is the second to launch so far this month for SpaceX, following the launch of a broadband satellite for Sirius XM on June 6. It was nothing but blue skies over the launch pad, and onlookers were treated to a gorgeous view as the rocket climbed to orbit. Today's flight marks the fourth GPS satellite delivery by SpaceX for the U.S. military. Three previous advanced GPS III missions also launched on Falcon 9 rockets, including two missions last year. Another of the satellites launched in August 2019 on the United Launch Alliance's final flight of the Delta IV Medium rocket. "If you've ever used your phone's mapping service or retrieved a location via a pin drop, you've used a satellite in this system," Zhou said.

Pie charts and scatter plots seem like ordinary tools, but they revolutionized the way we solve problems. From a report: John Carter has only an hour to decide. The most important auto race of the season is looming; it will be broadcast live on national television and could bring major prize money. If his team wins, it will get a sponsorship deal and a chance to start making some real profits for a change. There's just one problem. In seven of the past twenty-four races, the engine in the Carter Racing car has blown out. An engine failure live on TV will jeopardize sponsorships -- and the driver's life. But withdrawing has consequences, too. The wasted entry fee means finishing the season in debt, and the team won't be happy about the missed opportunity for glory. As Burns's First Law of Racing says, "Nobody ever won a race sitting in the pits."

One of the engine mechanics has a hunch about what's causing the blowouts. He thinks that the engine's head gasket might be breaking in cooler weather. To help Carter decide what to do, a graph is devised that shows the conditions during each of the blowouts: the outdoor temperature at the time of the race plotted against the number of breaks in the head gasket. The dots are scattered into a sort of crooked smile across a range of temperatures from about fifty-five degrees to seventy-five degrees. The upcoming race is forecast to be especially cold, just forty degrees, well below anything the cars have experienced before. So: race or withdraw?

This case study, based on real data, and devised by a pair of clever business professors, has been shown to students around the world for more than three decades. Most groups presented with the Carter Racing story look at the scattered dots on the graph and decide that the relationship between temperature and engine failure is inconclusive. Almost everyone chooses to race. Almost no one looks at that chart and asks to see the seventeen missing data points -- the data from those races which did not end in engine failure.
