hypnosec writes Stargazers are in for a treat: they will be able to witness a rare astronomical event early tomorrow morning (January 24, 2015) where shadows of three of Jupiter's largest moons — Io, Europa, and Callisto — will fall upon Jupiter simultaneously. Griffith Observatory in Los Angeles will provide a live online broadcast on its Livestream channel. It will begin on January 24 at 0430 GMT (January 23 at 11:30 PM EST, 8:30 PM PST) and end at 0700 GMT (2:00 AM EST, 11:00 PM PST). They've also posted a short animated video of how the event will appear.

Should Disney Require Its Employees To Be Vaccinated? 661

HughPickens.com writes According to Joanna Rothkopf Disneyland is already a huge petri dish of disease with tired children wiping their snot faces on Goofy and then riding log flumes through mechanized rivers filled with the backwash of thousands of other sweaty, unwashed, weeping toddlers. Now John Tozzi reports at Businessweek that five workers at Disneyland have been diagnosed with measles in an outbreak that California officials trace to visitors at the theme park in mid-December. The measles outbreak is a publicity nightmare for Disney and the company is urging its 27,000 workers at the park to verify that they're inoculated against the virus, and the company is offering tests and shots on site for workers who are unvaccinated. One thing Disney won't do, however, is require workers to get routine vaccinations as a condition of employment. Almost no companies outside the health-care industry do. "To make things mandatory just raises a lot of legal concerns and legal issues," says Rob Niccolini. Disney has been working with public health officials, and they've already put some employees on paid leave until medically cleared. "They recognized that they were just a meeting place for measles," says Gilberto Chávez. "And they are quite concerned about doing what they can to help control the outbreak."

StartsWithABang writes As the Hubble Space Telescope gets set to celebrate the 25th anniversary of opening its eyes to the Universe, it's important to realize that the first four years of operations were kind of a disaster. It wasn't until they corrected the flawed primary mirror and installed an upgraded camera — the Wide Field Planetary Camera 2 (WFPC2) — that the Universe truly came into focus. From 1993 to 2009, this workhorse camera literally changed our view of the Universe, and we're pushing even past those limits today.

New Advance Confines GMOs To the Lab Instead of Living In the Wild 130

BarbaraHudson (3785311) writes In Jurassic Park, scientists tweak dinosaur DNA so that the dinosaurs were lysine-deficient in order to keep them from spreading in the wild. Scientists have taken this one step further as a way to keep genetically modified E. coli from surviving outside the lab. In modifying the bacteria's DNA to thwart escape, two teams altered the genetic code to require amino acids not found in nature. One team modified the genes that coded for proteins crucial to cell functions so that that produced proteins required the presence of the synthetic amino acid in the protein itself. The other team focused on 22 genes deemed essential to a bacterial cell's functions and tied the genes' expression to the presence of synthetic amino acids. For the bacteria to survive, these synthetic amino acids had to be present in the medium on which the bacteria fed. In both cases, the number of escapees was so small as to be undetectable."

An anonymous reader writes The issue of how to use one robot across multiple terrains is an ongoing question in robotics research. In a paper published in Bioinspiration and Biomimetics today, a team from LIS, EPFL and NCCR Robotics propose a new kind of flying robot that can also walk. Called the DALER (Deployable Air-Land Exploration Robot), the robot uses adaptive morphology inspired by the common vampire bat, Desmodus rotundus, meaning that the wings have been actuated using a foldable skeleton mechanism covered with a soft fabric so that they can be used both as wings and as legs (whegs).

StartsWithABang writes The US Senate just voted on whether climate change is a hoax, knowing full well that debates or votes don't change what is or isn't scientifically true or valid. Nevertheless, debates have always been a thing in science, and they do have their place: in raising what points would be needed to validate, robustly confirm or refute competing explanations, theories or ideas. The greatest scientific debate in all of history — along with its conclusions — illustrates exactly this.

The Paradoxes That Threaten To Tear Modern Cosmology Apart 231

Posted by samzenpus
from the nobody-knows dept.
KentuckyFC writes Revolutions in science often come from the study of seemingly unresolvable paradoxes. So an interesting exercise is to list the paradoxes associated with current ideas in science. One cosmologist has done just that by exploring the paradoxes associated with well-established ideas and observations about the structure and origin of the universe. Perhaps the most dramatic of these paradoxes comes from the idea that the universe must be expanding. What's curious about this expansion is that space, and the vacuum associated with it, must somehow be created in this process. And yet nobody knows how this can occur. What's more, there is an energy associated with any given volume of the universe. If that volume increases, the inescapable conclusion is that the energy must increase as well. So much for conservation of energy. And even the amount of energy associated with the vacuum is a puzzle with different calculations contradicting each other by 120 orders of magnitude. Clearly, anybody who can resolve these problems has a bright future in science but may also end up tearing modern cosmology apart.

US Senate Set To Vote On Whether Climate Change Is a Hoax 666

from the who's-to-blame dept.
sciencehabit writes The U.S. Senate's simmering debate over climate science has come to a full boil today, as lawmakers prepare to vote on measures offered by Democrats that affirm that climate change is real—with one also noting that global warming is not "a hoax." In an effort to highlight their differences with some Republicans on climate policy, several Democrats have filed largely symbolic amendments to a bill that would approve the Keystone XL pipeline. They are designed to put senators on the record on whether climate change is real and human-caused.

SOTU: Community Colleges, Employers To Train Workers For High-Paying Coding Jobs 200

Posted by Soulskill
from the union-is-still-pretty-uniony dept.
theodp writes: Coding got a couple of shout-outs from the White House in Tuesday's State of the Union Address. "Thanks to Vice President Biden's great work to update our job training system," said President Obama (YouTube), "we're connecting community colleges with local employers to train workers to fill high-paying jobs like coding, and nursing, and robotics." And among the so-called "boats" in the new "River of Content" that the White House social media folks came up with to enhance the State of the Union is a card intended to be shared on Twitter & Facebook which reads, "Let's teach more Americans to code. (Even the President is learning!)." President Obama briefly addressed human spaceflight, saying, "I want Americans to win the race for the kinds of discoveries that unleash new jobs – converting sunlight into liquid fuel; creating revolutionary prosthetics, so that a veteran who gave his arms for his country can play catch with his kid; pushing out into the Solar System not just to visit, but to stay." He also called once more for action on climate change. Politifact has an annotated version of the transcript for more background information on Obama's statements, and FiveThirtyEight has a similar cheat sheet.

Interior of Burnt Herculaneum Scroll Read For First Time 66

from the old-grocery-lists dept.
New submitter Solandri writes: When Mt. Vesuvius erupted in A.D. 79, it destroyed a library of classical works in Herculaneum. The papyrus scrolls weren't incinerated, but were instead carbonized by the hot gases. The resulting black carbon cylinders have mostly withstood attempts to read their contents since their discovery. Earlier attempts to unfurl the scrolls yielded some readable material, but were judged too destructive. Researchers decided to wait for newer technology to be invented that could read the scrolls without unrolling them.

Now, a team led by Dr. Vito Mocella from the National Research Council's Institute for Microelectronics and Microsystems (CNR-IMM) in Naples, Italy has managed to read individual letters inside one of the scrolls. Using a form of x-ray phase contrast tomography (abstract), they were able to ascertain the height difference (about 0.1mm) between the ink of the letters and the papyrus fibers which they sat upon. Due to the fibrous nature of the papyrus and the carbon-based ink, regular spectral and chemical analysis had thus far been unable to distinguish the ink from the paper. Further complicating the work, the scrolls are not in neat cylinders, but squashed and ruffled as the hot gases vaporized water in the papyrus and distorted the paper.

evanak writes TIROS was NASA's Television Infrared Observation Satellite. It launched in April 1960. One of the ground tracking stations was located at the U.S. Army's secret "Camps Evans" Signals Corps electronics R&D laboratory. That laboratory (originally a Marconi wireless telegraph lab) became the InfoAge Science Center in the 2000s. [Monday], after many years of restoration, InfoAge volunteers (led by Princeton U. professor Dan Marlowe) successfully received data from space. The dish is now operating for the first time in 40 years! The received data are in very raw form, but there is a clear peak riding on top of the noise background at 0.4 MHz (actually 1420.4 MHz), which is the well-known 21 cm radiation from the Milky Way. The dish was pointing south at an elevation of 45 degrees above the horizon.

The paper, published Monday in the Annals of Internal Medicine (abstract), found that prolonged sedentary behavior was associated with a 15 to 20 per cent higher risk of death from any cause; a 15 to 20 per cent higher risk of heart disease, death from heart disease, cancer, death from cancer; and as much as a 90 per cent increased risk of developing diabetes, said Alter. And that was after adjusting for the effects of regular exercise. ... Engaging in 30 to 60 minutes of moderate to vigorous daily exercise does not mean it's OK to then "sit on your rear" for the rest of the day.

mpicpp writes with a report that Google is close to finalizing an investment in SpaceX to fund the rocket company's vision for satellite-based, low-cost internet access. According to The Information (paywalled), Google is one of many investors for this round of fundraising. The Wall Street Journal (also paywalled) reports Google's investment at $1 billion. They add, "It is likely to take years to establish designs and potentially set up a specialized satellite-making facility. But SpaceX already has some important building blocks. Industry officials said the company builds its own navigation and flight-control systems for spacecraft, which could provide some elements for satellites. There also are synergies between parts SpaceX makes today for solar arrays on spacecraft and such devices intended for satellites."

jones_supa writes: The next game from the mind of veteran strategy and simulation game designer Sid Meier has been revealed. 2K and Firaxis Games have announced Sid Meier's Starships, a turn-based interstellar strategy game scheduled to arrive in early 2015 for Windows, OS X, and iOS (iPad). In the game, you control a fleet of starships as you journey through the galaxy to complete missions, protect planets and their inhabitants, and build a planetary federation. As you trek through the stars, you will be challenged to expand your federation's influence and reach. You shall also amass futuristic technology and take part in combat using a deep roster of customizable ships. When designing Starships, Meier was intrigued by the idea of exploring the next chapter in the story of Civilization: Beyond Earth. "What happens after we colonize our new home and eventually build starships to take to the stars? What has become of our long-lost brothers and sisters from the planet Earth," Meier asks. "My goal was to create an experience that focuses on starship design and combat within a universe filled with interstellar adventure, diplomacy, and exploration."
