Ensuring fresh air for all

Tue, 20 Feb 2018 10:38:36 GMT

Paris (ESA) Feb 20, 2018
(image) A start-up company from an ESA business incubator is offering affordable air-quality monitors for homes, schools and businesses using technology it developed for the International Space Station. "We realised that the problem astronauts face with limited of exchange of air inside the International Space Station is also the case for many people inside buildings that have little or no ventila



Iridium Certus broadband readies for DOD wsers with COMSAT

Tue, 20 Feb 2018 10:38:36 GMT

McLean VA (SPX) Feb 20, 2018
(image) Iridium Communications Inc. reports that COMSAT, Inc., has signed an agreement to become an Iridium Certus service provider for U.S. Department of Defense (DoD) users. This unique, long-term deal will allow COMSAT Inc. to provide Iridium's secure global satellite broadband connectivity for mobile voice and data services to the Department of Defense (DoD) beginning in mid-2018. COMSAT, Inc.



Light pollution threatens Chile's dark skies

Tue, 20 Feb 2018 10:38:36 GMT

Paranal, Chile (AFP) Feb 17, 2018
(image) It seems nothing can escape the inexorable spread of light pollution - not even the giant telescopes probing the heavens above northern Chile, a region whose pristine dark skies, long considered a paradise for astronomers, are under increasing threat. The Atacama desert, 1,200 kilometers (750 miles) north of the capital Santiago, provides ideal conditions where astronomers study the stars i



Defying US, Paris and Berlin stand firm on EU defence pact

Tue, 20 Feb 2018 10:38:36 GMT

Munich, Germany (AFP) Feb 16, 2018
(image) Europe must be able to stand on its own feet militarily, France and Germany said Friday as they made the case for a new EU defence pact that has rattled Washington. In opening remarks at the Munich Security Conference, French Defence Minister Florence Parly and her German counterpart Ursula von der Leyen said the EU plan posed no threat to NATO. But they stressed that the European Union



Cyberattacks are costly, and things could get worse: US report

Tue, 20 Feb 2018 10:38:36 GMT

Washington (AFP) Feb 16, 2018
(image) Cyberattacks cost the United States between $57 billion and $109 billion in 2016, a White House report said Friday, warning of a "spillover" effect for the broader economy if the situation worsens. A report by the White House Council of Economic Advisers sought to quantify what it called "malicious cyber activity directed at private and public entities" including denial of service attacks, d



Artificial intelligence poses questions for nature of war: Mattis

Tue, 20 Feb 2018 10:38:36 GMT

Washington (AFP) Feb 18, 2018
(image) Artificial intelligence and its impact on weapons of the future has made US Defense Secretary Jim Mattis doubt his own theories on warfare. A question on the subject prompted the retired Marine general to give an impromptu seminar on his theory of war Saturday to reporters returning with him from a week-long tour of Europe. Recalling his own writings, he differentiated between the essent



New hole-punched crystal clears a path for quantum light

Tue, 20 Feb 2018 10:38:36 GMT

College Park MD (SPX) Feb 20, 2018
(image) Optical highways for light are at the heart of modern communications. But when it comes to guiding individual blips of light called photons, reliable transit is far less common. Now, a collaboration of researchers from the University of Maryland's Joint Quantum Institute (JQI), led by Associate Professor Mohammad Hafezi and Professor Edo Waks, has created a photonic chip that both generates sing



CALIFA renews the classification of galaxies

Tue, 20 Feb 2018 10:38:36 GMT

Canary Islands, Spain (SPX) Feb 20, 2018
(image) The objects within galaxies have two basic types of motions: orbiting around the galaxy centre in a regular organized disc, or in orbits oriented at random without a clear direction of rotaiton. If we imagined that galaxies behave in the same way as the Solar System we could think that as the objects move further away from the centre their orbital velocities decrease. However this is not n



New technology can help scientists peer into deep space

Tue, 20 Feb 2018 10:38:36 GMT

Canberra, Australia (SPX) Feb 20, 2018
(image) A team of Australian scientists, including researchers from The Australian National University (ANU), have found a new way to use the telecommunications network to synchronise radio telescopes, which help scientists peer into deep space. Linking radio telescopes in an array currently requires that each telescope has access to an atomic clock to record the precise time when a signal is dete



Distant galaxy group contradicts common cosmological models, simulations

Tue, 20 Feb 2018 10:38:36 GMT

Irvine CA (SPX) Feb 20, 2018
(image) An international team of astronomers has determined that Centaurus A, a massive elliptical galaxy 13 million light-years from Earth, is accompanied by a number of dwarf satellite galaxies orbiting the main body in a narrow disk. In a paper published in Science, the researchers note that this is the first time such a galactic arrangement has been observed outside the Local Group, home to the Milk



Satellite galaxies of Centaurus A are on a coordinated dance

Tue, 20 Feb 2018 10:38:36 GMT

Washington DC (SPX) Feb 20, 2018
(image) The satellite dwarf galaxies orbiting around the much larger galaxy Centaurus A are rotating in synchrony around their host, to researchers' surprise. (Researchers expected them to orbit at random). The results contradict simulations based on standard cosmology, which predict that fewer than 1% of satellite systems should exhibit this synchronous behavior. Because our own Milky Way and the



New study challenges popular theory about dwarf galaxies

Tue, 20 Feb 2018 10:38:36 GMT

Canberra, Australia (SPX) Feb 20, 2018
(image) A new international study involving The Australian National University (ANU) has found a plane of dwarf galaxies orbiting around Centaurus A in a discovery that challenges a popular theory about how dwarf galaxies are spread around the Universe. Co-researcher Associate Professor Helmut Jerjen from ANU said astronomers had previously observed planes of dwarf galaxies whirling around our gal



News about Tabby's star, the most mysterious star of 2017

Tue, 20 Feb 2018 10:38:36 GMT

Canary Islands, Spain (SPX) Feb 20, 2018
(image) KIC 8462852, or "Tabby's Star" named after Tabetha Boyajian, the researcher at Louisiana State University (USA) who is leading its study, is a medium sized star, some 50% bigger than the Sun, and 1,000 degrees hotter, at a distance of around 1000 light years. However its brightness has been rising and falling sporadically, without a known explanation. Many theories and speculations of different



A new way of generating ultra-short bursts of light

Tue, 20 Feb 2018 10:38:36 GMT

Stanford CA (SPX) Feb 20, 2018
(image) Although critical for varied applications, such as cutting and welding, surgery and transmitting bits through optical fiber, lasers have some limitations - namely, they only produce light in limited wavelength ranges. Now, researchers from the Ginzton Lab at Stanford University have modified similar light sources, called optical parametric oscillators, to overcome this obstacle. Until now,



UMass Amherst physicists speed up droplet-wrapping process

Tue, 20 Feb 2018 10:38:36 GMT

Amherst MA (SPX) Feb 16, 2018
(image) Experimental physicists at the University of Massachusetts Amherst has reported that they have developed a fast, dynamic new process for wrapping liquid droplets in ultrathin polymer sheets, so what once was a painstaking process taking tens of minutes can now be done in a fraction of a second. Physics professor Narayanan Menon, with current postdoctoral researcher Deepak Kumar, former pos
