Posted: October 16, 2018 AP Stocks surge on earnings and economic data; Dow climbs 500 October 16, 2018 NEW YORK (AP) — World stock markets are rallying Tuesday, and U.S. stocks are on track for their second-largest gain in 2018 following strong earnings reports from major U.S. companies in finance and health care. Technology companies are also rising after their recent slump. The Dow Jones Industrial Average rose as much as 502 points.Even with the big gains, major indexes are still broadly lower for the month following a two-day rout last week that erased nearly 1,400 points from the Dow.Investors were encouraged by some good news on the economy. The Federal Reserve said output by U.S. factories, mines and utilities climbed in September despite the effects of Hurricane Florence, and the Labor Department said U.S. employers posted the most jobs in two decades in August while hiring continued to increase.KEEPING SCORE: The S&P 500 index jumped 54 points, or 2 percent, to 2,805 as of 2:45 p.m. Eastern time. The Dow gained 494 points, or 2 percent, to 25,745.The Nasdaq composite climbed 192 points, or 2.6 percent, to 7,623 as technology companies reversed some of their outsize losses from the last few days. The Russell 2000 index of smaller-company stocks rose 39 points, or 2.6 percent, to 1,592.Earnings for U.S. companies climbed about 20 percent in each of the first two quarters of 2018 as economic growth picked up and corporate taxes were slashed. Analysts expect similar results in the current period.Stocks have gyrated over the last three days following a six-day losing streak that included some of their biggest declines of the year. The S&P 500 fell 6.9 percent from its record high on Sept. 20 to its recent low on Thursday. It remains 4.3 percent below that record level.HEALTHY…: UnitedHealth, the largest U.S. health insurer and provider of privately-run Medicare Advantage plans, once again topped Wall Street forecasts and raised its projections for the year. The stock climbed 4.1 percent to $270.95. Other health insurers also rose. Cigna advanced 3.8 percent to $211.70 and Humana rose 3.4 percent to $327.90. Medicaid service company Molina Healthcare jumped 4.1 percent to $144.26.Health care products giant Johnson & Johnson added 1.4 percent to $135.89 after it said prescription sales jumped. Its results, too, were stronger than analysts expected.…AND WEALTHY: Morgan Stanley rose 5.7 percent to $45.94 and Goldman Sachs added 2.4 percent to $220.38 after the two investment banks did better than expected in the third quarter, helped by strong performance in their trading operations and better-than-expected revenue from stock underwriting. Morgan Stanley’s stock has fallen 12 percent this year and Goldman has lost almost 14 percent.TECH UPDATE: Technology companies rose. Microsoft jumped 2.8 percent to $110.65 and Adobe rallied 8.6 percent to $258.36 after it backed its fourth-quarter profit and revenue forecasts. The stock has jumped 47 percent this year, but had slumped in recent days. Internet companies also advanced. Alphabet, Google’s parent company, rose 2.4 percent to $1,128.80.Email delivery company Sendgrid climbed 14.8 percent to $35.50 after cloud communications platform company Twilio agreed to buy it for $36.92 per share in stock, or $1.7 billion. Twilio fell 3.4 percent to $73.56.SUSPENSE FOR NETFLIX: Netflix rose 2.7 percent to $342.04 ahead of its third-quarter report Tuesday afternoon. The streaming video company has struggled over the past three months and has fallen almost 20 percent since its second-quarter report, when it posted disappointing subscriber totals and gave a weaker forecast than analysts expected.It’s still up 78 percent this year, the third-best of any S&P 500 stock.O CANNABIS: On Wednesday Canada will legalize marijuana nationwide. While cannabis companies mostly traded lower Tuesday, the stocks have made huge gains this year in highly volatile trading. Tilray fell 5.7 percent to $156.27 while Canopy Growth shed 7.1 percent to $52.87.On Tuesday Benchmark Capital analyst Mike Hickey started coverage of Tilray with a $200 price target, saying its supply deals with pharmacies and a partnership with drugmaker Novartis will help make it an early leader in the market. Hickey valued the Canadian cannabis market at about $3.2 billion in 2019 and said it will climb to $8.1 billion by 2023.Tilray’s market value stands at $14.5 billion, up ninefold since it went public in mid-July, and Canopy Growth has more than doubled in value to $12 billion. Canopy announced a $4 billion investment from Corona beer maker Constellation Brands in August. The huge gains reflect investors’ view that that other countries will legalize marijuana in the years to come.ENERGY: U.S. benchmark crude oil added 0.2 percent to $71.92 per barrel in New York. Brent crude, the international standard, rose 0.4 percent to $81.14 per barrel in London.Wholesale gasoline rose 1.7 percent to $1.98 a gallon and heating oil picked up 0.6 percent to $2.34 a gallon.

Listen This past spring, a slew of top administrators decided to leave or retire from the Houston Independent School District, including the chief of staff and deputy superintendent.News 88.7 obtained exit interviews with about a dozen of those former employees, who describe a culture of fear, “nasty politics,” and retaliation.The state conservator, Doris Delaney, who monitors Houston’s most troubled schools, interviewed half of the administrators and principals who’ve left between January and June 2018. Their tenure ranged from just under a year to over three decades.Their reasons for leaving? They cited a lack of trust, concern about the district’s future and instability and negativity from the school board. Some former employees made comments like “I pray, literally, the Board will be taken over” and “Will TEA please step in and take over.” 00:00 /00:57 X To embed this piece of audio in your site, please use this code: Share HISD has been under pressure by the Texas Education Agency, or TEA, to improve chronically low-performing schools or face a potential state-appointed board of managers.More than half of the outgoing employees said that they were either unsure or would not recommend Houston ISD to prospective employees.“Just reading through these responses, the feeling is that people feel almost a sense of betrayal,” said Jon Taylor, who teaches political science at the University of St Thomas. Taylor said that the exit interviews reveal deep dysfunction.“They talk about things such as their voices not being heard, about toxicity of the administration, about the turnover of administration, particularly at the highest levels,” Taylor said.“There’s a gallows humor that’s in play, there’s a culture of fear, there’s a fear of not only losing their job, but of retaliation and demotion, a fear that you have a leadership group at the very top — the superintendent and the board — who are detached from the realities of the district.”The Houston Independent School District declined to comment on the exit interviews.
The team proposes two main scientific goals for JWST when it comes to observing these moons. The first task would be completing the infrared survey of major satellites. The second goal is geology-related and described as “monitoring surface changes of active satellites.” The researchers presented their proposal in a paper published on the arXiv.”The James Webb Space Telescope will allow observations with a unique combination of spectral, spatial, and temporal resolution for the study of outer planet satellites within our solar system. We highlight the infrared spectroscopy of icy moons and temporal changes on geologically active satellites as two particularly valuable avenues of scientific inquiry,” the scientists wrote in the paper.JWST will be equipped in four scientific instruments: the Near InfraRed Camera (NIRCam), the Near InfraRed Spectrograph (NIRSpec), the Mid-Infrared Instrument (MIRI) and the Fine Guidance Sensor/Near Infrared Imager and Slitless Spectrograph (FGS/NIRISS).These instruments provide a unique opportunity to obtain high spectral resolution infrared spectra from planetary satellites in wavelength regions that cannot be observed from Earth. JWST’s results could complement observations of outer solar system moons conducted by Voyager and Cassini missions.The scientists hope that the telescope’s key scientific contribution could be determining the compositions of giant gas planets’ irregular satellites. They note that even at very low spatial resolution, near-infrared spectroscopy is sensitive to H2O and other ices, as well as silicates and spectral slopes characteristic of complex organic “tholins” (heteropolymer molecules formed by solar ultraviolet irradiation of simple organic compounds such as methane or ethane).”JWST has the sensitivity to provide unique compositional data on irregular satellites. For example, in the one to 2.5 micron region of the near-infrared, amorphous vs. crystalline surface composition of icy bodies could be surveyed extensively using JWST NIRSpec,” the paper reads.Irregular satellites are important sources of dust in the giant planet systems. Dust orbits evolve under effects of radiation pressure and solar tides. By linking the sizes, densities, and albedos of dust particles to the source satellite surface compositions, JWST could offer new insights into the role of these satellites in the production of dust particles.

We highlight the infrared spectroscopy of icy moons and temporal changes on geologically active satellites as two particularly valuable avenues of scientific inquiry. While some care must be taken to avoid saturation issues, JWST has observation modes that should provide excellent infrared data for such studies.

Image credit: Northrop Grumman. Journal information: arXiv The observations of geologic activity of the outer solar system moons, described by Kestay and his colleagues as the second main goal for JWST could also bring remarkable scientific results. The telescope will be able to detect changes on the surface that are indicative of temporal variations in composition and temperature.Many of the outer planet satellites are remarkably active. For instance, Jupiter’s moon Io, Neptune’s largest moon Triton, and Enceladus, Saturn’s icy satellite, have active eruptions. The recent suggestion of active plumes above Europa, orbiting Jupiter, is especially exciting because it may provide samples from a habitable environment that is otherwise extremely challenging to access.The scientists believe that the best moon for these observations would be Io. They note that JWST could observe significant surface changes on this satellite where volcanic activity is very high.”The observations every six months that JWST can make of the Jovian system is very well suited for monitoring the creation and fading of colorful plume deposits on Io which typically happen on a timescales of several months and have diameters of many hundreds of kilometers,” the researchers wrote.They are convinced that JWST observations could also resolve other scientific problems related to Io, such as the eruption temperature of its lavas and the uncertainty about the composition and state of its mantle. This could be crucial to our understanding of how tidal heating works in the Jovian system.The researchers conclude that these two types of JWST observations will enable compelling science of outer solar system moons. They present the telescope as an important tool for studying planetary satellites, underlining that the road to understanding the origins of the universe leads through the observations of our outer solar system. Finally, they encourage the scientific community to use their paper to formulate more specific observation plans. This document is subject to copyright.

NASA’s James Webb Space Telescope (JWST), often touted as Hubble’s successor, is slated to be launched in 2018 to study every phase of cosmic history, mainly by observing the most distant objects in the universe. The telescope will also be useful for investigating extrasolar planetary systems as well as planets within our solar system. Now, a team of researchers led by Laszlo Kestay, the director of the U.S. Geological Survey’s Astrogeology Science Center, has laid out its plan to use the telescope’s capabilities to better understand our planetary neighborhood by putting emphasis on outer solar system moons and their geology.
