Superflares From Young Red Dwarf Stars Imperil Planets  Baltimore MD (SPX) Oct 25, 2018 - The word "HAZMAT" describes substances that pose a risk to the environment, or even to life itself. Imagine the term being applied to entire planets, where violent flares from the host star may make worlds uninhabitable by affecting their atmospheres. NASA's Hubble Space Telescope is observing such stars through a large program called HAZMAT - Habitable Zones and M dwarf Activity across Ti ... more |

Putin warns of a new 'arms race' with America  Moscow (AFP) Oct 24, 2018 - President Vladimir Putin warned Wednesday of a new arms race if America pulls out of weapons treaties, and said Russia would respond "in kind" to any new US missiles placed on European soil. At the weekend, US President Donald Trump sparked concerns globally when he said he would ditch a key Cold War-era nuclear weapons pact, the three-decade-old Intermediate-Range Nuclear Forces Treaty (INF ... more |

Israel wins $777 mn Indian missile defence order  Jerusalem (AFP) Oct 24, 2018 - Israel Aerospace Industries (IAI) said Wednesday it had won a $777 million (680 million euro) order from India to buy defence systems for its navy. The deal with India's state-owned Bharat Electronics Limited to supply the marine version of the Barak 8 air and missile defence system for seven more warships follows a $630 million (551 million euro) order placed last year. State-owned IAI, ... more |

In five -10 years, gravitational waves could accurately measure universe's expansion  Chicago IL (SPX) Oct 24, 2018 - Twenty years ago, scientists were shocked to realize that our universe is not only expanding, but that it's expanding fasterover time. Pinning down the exact rate of expansion, called the Hubble constant after famed astronomer and UChicago alumnus Edwin Hubble, has been surprisingly difficult. Since then scientists have used two methods to calculate the value, and they spit out distressing ... more |

Researchers develop an operative complex scheme for short-range weather forecasts  Moscow, Russia (SPX) Oct 25, 2018 - Staff members from the Higher School of Economics and the Hydrometeorological Centre of Russia have proposed a new operative scheme for the short-range complex forecasting of wind and possible gusts, surface air temperature, and humidity. The results, i.e., estimates of average forecast errors at different lead times and their comparison with competitors' results, were published in the journal R ... more |

Ice-age climate clues unearthed  Houston TX (SPX) Oct 25, 2018 - How cold did Earth get during the last ice age? The truth may lie deep beneath lakes and could help predict how the planet will warm again. Sediments in lake beds hold chemical records of ages past, among them the concurrent state of the atmosphere above. Scientists led by a Rice University professor and her colleagues have devised a new computational model to interpret what they reveal. S ... more |

Origami, 3D printing merge to make complex structures in one shot  Atlanta GA (SPX) Oct 23, 2018 - By merging the ancient art of origami with 21st century technology, researchers have created a one-step approach to fabricating complex origami structures whose light weight, expandability, and strength could have applications in everything from biomedical devices to equipment used in space exploration. Until now, making such structures has involved multiple steps, more than one material, and as ... more |

More goals in quantum soccer  Bonn, Germany (SPX) Oct 25, 2018 - Let's suppose you were allowed to blindfold German soccer star Timo Werner and turn him on his own axis several times. Then you'd ask him to take a shot blind. It would be extremely unlikely that this would hit the goal. With a trick, Bonn physicists nevertheless managed to achieve a 90-percent score rate in a similar situation. However, their player was almost 10 billion times smaller tha ... more |

Moscow (AFP) Oct 25, 2018 - Russia on Thursday successfully launched a Soyuz rocket for the first time since the failure of a similar rocket aborted a manned take-off to the International Space Station (ISS) on October 11. "On Thursday at 03:15 (0015 GMT) a Soyuz-2.1B rocket was successfully launched carrying a satellite for the Russian military," the Russian defence ministry said in a statement. The satellite rea ... more 
Nagoya, Japan (SPX) Oct 26, 2018 - When we walk on a sandy beach in summer we may find holes dug in the sand in the vicinity of the shoreline. Often these are entrances to sand crab burrows (Fig. 1). It is striking that the sizes (entrance diameters) of the burrows have a typical value (about 2 - 3 cm). Moreover, one never seems to find any very wide entrances (e.g. 10 cm in diameter). Why do crabs only dig narrow burrows? Of cou ... more 
Paris (ESA) Oct 26, 2018 - Since 13 September, ESA's Mars Express has been observing the evolution of an elongated cloud formation hovering in the vicinity of the 20 km-high Arsia Mons volcano, close to the planet's equator. In spite of its location, this atmospheric feature is not linked to volcanic activity but is rather a water ice cloud driven by the influence of the volcano's leeward slope on the air flow - som ... more 
Tucson AZ (SPX) Oct 26, 2018 - JAXA's (Japan Aerospace Exploration Agency's) Hayabusa2 mission is on track to return samples from its target asteroid, 162173 Ryugu, a C-type near-Earth asteroid (NEA). The past month has seen the successful deployment of two rovers and a lander. The mission focus is now on the successful retrieval and return of a surface sample. Two members of the Planetary Science Institute's (PSI's) sc ... more 
Hamburg, Germany (SPX) Oct 26, 2018 - About 66 million years ago, a meteorite hit the Earth of the Yucatan Peninsula in what is now Mexico. This event triggered a mass extinction that eradicated approximately 75 percent of all species and ended the era of dinosaurs. Like Prof. Dr. Ulrich Riller of the Institute of Geology of the University of Hamburg and co-workers report in "Nature", the hitherto mysterious formation of the c ... more 
Bethlehem PA (SPX) Oct 25, 2018 - What would it take to meet the world's energy needs, sustainably, far into the foreseeable future? Perhaps creating energy the way the sun does, through nuclear fusion. Fission and fusion are very different nuclear reactions, according to Eugenio Schuster, Professor in the Department of Mechanical Engineering and Mechanics at Lehigh University. Fission, which produces the type of nuclear e ... more 
Charlottesville VA (SPX) Oct 24, 2018 - Jupiter's icy moon Europa has a chaotic surface terrain that is fractured and cracked, suggesting a long-standing history of geologic activity. A new series of four images of Europa taken with the Atacama Large Millimeter/submillimeter Array (ALMA) has helped astronomers create the first global thermal map of this cold satellite of Jupiter. The new images have a resolution of roughly 200 k ... more 
Tucson AZ (SPX) Oct 25, 2018 - Mysterious straight bright stripes have been discovered on Saturn's moon Dione, says research by Planetary Science Institute Associate Research Scientist Alex Patthoff. The origins of these linear virgae (virgae meaning a stripe or streak of color) are most likely caused by the draping of surface materials like material from Saturn's rings, passing comets, or co-orbital moons Helene and Po ... more
