Avaruuden tutkimukseen liittyen mainitaan vielä ohimennen, että Google Mapsin kuvat alueella, jossa FAST -teleskooppi on rakenteilla, ovat päivittyneet joku aika sitten ja ohesta kiinnostuneet voi vilkaista miltä FAST näyttää. FAST on siis Kiinassa rakenteilla oleva maailman suurin radioteleskooppi. Mammutin halkaisija on noin 500 metriä. Teleskoopin rakennustyöt ovat edenneet hyvin ja teleskooppi valmistunee suunnitelmien mukaisesti 2016.

Viimeisen vajaan 15 vuoden aikana Ukrainan Galenki RT-70 radioteleskoopilla on lähetetty 4 kertaa viestejä mahdollisille lähitähtien alieneille. Lähin viestin saava tähti on 20 valovuoden etäisyydellä oleva Gliese 581. Kaikkiaan viestejä on lähetetty 17 tähdelle, jotka sijaitsevat 20-70 valovuoden etäisyydellä. Ohessa lisää juttua lähetetyistä viesteistä.

A senior researcher at the Large Hadron Collider says a new particle could be detected this year that is even more exciting than the Higgs boson. The accelerator is due to come back online in March after an upgrade that has given it a big boost in energy. This could force the first so-called supersymmetric particle to appear in the machine, with the most likely candidate being the gluino.
Collider hopes for a 'super' restart
Pienet, kylmät tähdet ovat maailmankaikkeuden yleisinpiä tähtiä. Niistä vähintään joka toisella tiedetään olevan ympärillään myös kivisiä planeettoja. Aiempien tutkimusten mukaan punaisia kääpiötähtiä kiertävät planeetat ovat yleensä aina joko liian kylmiä tai täysin kuivia voidakseen olla elämälle sopivia. Tuoreen kolmiulotteisen ilmastomallinnuksen perusteella vanha näkemys on väärä - planeetat saattavat sittenkin pysyä kosteina.
Kääpiötähtien planeetat ovat riittävän kosteita elämälle
Näin tulee ilmeisesti tapahtumaan "jo" 1,5 miljoonan vuoden kuluttua kun Gliese 710 saapuu aurinkokunnan liepeille. Lähimmillään tähti käy noin 0,7 valovuoden etäisyydellä. Tähti kulkeen Oortin pilven läpi ja tullee lähettämään komeettoja aurinkokunnan sisäosiin.Aurinkoa lähinnä oleva tähti on noin 4,2 valovuoden päässä. Tämä lienee melkein kaikkien tiedossa. Turhana tietona tähän voi kuitenkin lisätä, että niin menneisyydessä kuin myös tulevaisuudessa Aurinkoa lähinnä olleva tähti voi olla alle valovuoden etäisyydellä.

An alien star passed through our Solar System just 70,000 years ago, astronomers have announced. The object, a red dwarf known as Scholz's star, cruised through the outer reaches of the Solar System - a region known as the Oort Cloud. Observations of the star's trajectory suggest that 70,000 years ago this cosmic infiltrator passed within 0.8 light years of the Sun. By comparison, Proxima Centauri is 4.2 light years away.
"There are trillions of comets in the Oort cloud and likely some of them were perturbed by this object, and some may have been perturbed onto orbits which will bring them into the inner solar system (in the distant future)," he told BBC News. "But so far it seems unlikely that this star actually triggered a significant 'comet shower'."
Alien star system buzzed the Sun
Shostak argues that exotic possibilities might be available to a very technologically advanced society. If a telescope were placed at a distance of 550 times the Earth's distance from the sun, it would be in a position to use the sun's gravitational field as a gigantic lens. This would give it an effective collecting area vastly larger than the city of Chicago, for free. If advanced extraterrestrials made use of their star's gravitational field in this way, Shostak maintains "that would give them the capacity to observe many varieties of terrestrial transmissions, and in the optical they would have adequate sensitivity to pick up the glow of street lamps".
The controversy over interstellar messaging
Nyt tutkijat kuitenkin piilottivat ensimmäisen havainnon tiedot, ja yrittivät veikata piirin kvanttitilaa käyttämällä hyväksi tietoa jälkimmäisestä kvanttitilasta. Näin onnistumistodennäköisyys saatiin nostettua 90 prosenttiin.
Tutkijoiden mukaan tulos on parhaiten selitettävissä, jos ajan ajatellaan olevan perusluonteeltaan symmetrinen. Niin sanottu ajan nuoli, joka normaalimaailmassa osoittaa menneisyydestä tulevaisuuteen, osoittaisikin siis kvanttimaailmassa molempiin suuntiin.
'We know now of seven craters in the Arctic area,' he said. 'Five are directly on the Yamal peninsula, one in Yamal Autonomous district, and one is on the north of the Krasnoyarsk region, near the Taimyr peninsula. 'We have exact locations for only four of them. The other three were spotted by reindeer herders. But I am sure that there are more craters on Yamal, we just need to search for them.
'Studying the satellite images we found out that initially there were no craters nor a lake. Some craters appeared, then more. Then, I suppose that the craters filled with water and turned to several lakes, then merged into one large lake, 50 by 100 metres in diameter. 'This big lake is surrounded by the network of more than 20 'baby' craters now filled with water and I suppose that new ones could appear last summer or even now. We now counting them and making a catalogue.
'No one knows what is happening in these craters at the moment. We plan a new expedition. Also we want to put not less than four seismic stations in Yamal district, so they can fix small earthquakes, that occur when the crater appears. 'In two cases locals told us that they felt earth tremors. The nearest seismic station was yet too far to register these tremors.

Plans to generate electricity from the world's first series of tidal lagoons have been unveiled in the UK. The six lagoons - four in Wales and one each in Somerset and Cumbria - will capture incoming and outgoing tides behind giant sea walls, and use the weight of the water to power turbines. A £1bn Swansea scheme, said to be able to produce energy for 155,000 homes, is already in the planning system.

Scientists have unearthed the jawbone of what they claim is one of the very first humans. The 2.8 million-year-old specimen is 400,000 years older than researchers thought that our kind first emerged. The head of the research team told BBC News that the find gives the first insight into "the most important transitions in human evolution".
Prof Brian Villmoare of the University of Nevada in Las Vegas said the discovery makes a clear link between an iconic 3.2 million-year-old hominin (human-like primate) discovered in the same area in 1974, called "Lucy".

The effort to build a synchrotron in Africa is gaining momentum, its leading proponent has told a US conference. Prof Winick, an eminent physicist from Stanford University and the SLAC National Accelerator Laboratory in California, highlighted the uneven scattering of the 50-plus light sources on a world map.
"Glaring on this map is the absence of any red dot here," he said, pointing to the African continent. "It's very relevant that Africa has such facility, so that dedicated, motivated African scientists can work on problems - biomedical, environmental - that are of particular interest to that region."

A record-breaking attempt to fly around the world in a solar-powered plane is set to get under way on Monday. The aircraft - called Solar Impulse-2 - will take off from Abu Dhabi and head east, first to Oman, and then to India. Over the next five months, it will skip from continent to continent, crossing both the Pacific and Atlantic oceans in the process.
This new model has a wingspan of 72m, which is wider than a 747 jumbo jet. And yet, it weighs only 2.3 tonnes. Its light weight will be critical to its success. So, too, will the performance of the 17,000 solar cells that line the top of the wings, and the energy-dense lithium-ion batteries it will use to sustain night-time flying. Operating through darkness will be particularly important when the men have to cross the Pacific and the Atlantic.
Solar Impulse plane set for epic global flight
The possibility that other universes exist beyond our own universe is tantalizing, but seems nearly impossible to test. Now a group of physicists has suggested that the Large Hadron Collider (LHC), the largest particle collider in the world, may be able to uncover the existence of parallel universes, should they exist. In a new paper published in Physics Letters B, Ahmed Farag Ali, Mir Faizal, and Mohammed M. Khalil explain that the key to finding parallel universes may come from detecting miniature black holes at a certain energy level. The detection of the mini black holes would indicate the existence of extra dimensions, which would support string theory and related models that predict the existence of extra dimensions as well as parallel universes.
So far, the LHC has searched for mini black holes at energy levels below 5.3 TeV. According to gravity's rainbow, this energy is too low. Instead, the model predicts that black holes may form at energy levels of at least 9.5 TeV in six dimensions and 11.9 TeV in 10 dimensions. Since the LHC is designed to reach 14 TeV in future runs, these predicted energy requirements for black hole production should be accessible.

Tutkijat ovat havainneet viimeisten viidentoista vuoden aikana 10 erikoista radiopulssia, jotka tulevat avaruudesta. Havainnoista on kertonut muun muassa New Scientist (jo ennen aprillipäivää). Jokainen pulssi leviää lukuisille eri taajuuksille, aivan kuin kaikki radiotaajuudet soittaisivat samaa musiikkikappaletta yhtä aikaa. Alimman ja ylimmän radiotaajuuden saapumisajoissa on kuitenkin pieni ero. Jokaisessa havaitussa 10 pulssissa tämä ero on numeron 187,5 monikerta. Mikään toistaiseksi tunnettu luonnonprosessi ei tuota havaittua säännöllisyyttä. Yksi hyvä selitysmahdollisuus on, että kyseessä olisi lähellä sijaitseva kohde, kuten jonkin valtion vakoilusatelliitti, jonka sijainti on pidetty salassa.
"Tämä voi olla uutta fysiikkaa, kuten uudenlainen pulsari, tai jos lopulta pystymme sulkemaan pois kaiken muun, Maan ulkopuoliset olennot", kommentoi tutkija Michael Hippke Neukirchen-Vluynin data-analyysin instituutista Saksasta. SETI-tutkimuksen piirissä on jo pitkään spekuloitu, että juuri matemaattinen säännönmukaisuus voisi erottaa vieraan sivilisaation viestin luonnon tuottamasta signaalista.
Avaruuden radiopulsseista löytyi outo säännönmukaisuus

After years of planning, the first steps of tearing down and moving the town of Kiruna started today. The lifeblood of Kiruna is the LKAB iron mine, and ironically the mine also threatened to be its end. Years ago LKAB announced that to keep the mine in operation they had to dig under the very center of the town itself, with a risk that would undermine all the buildings there. So the mining company is paying an estimated 12 billion kronor to move the entire town, altogether some 3000 apartments and many other buildings. On Wednesday the first housing in the section closest to the new mining extension went under the wreckers ball.

A Canadian inventor has set a new world record for hoverboard flight distance, hovering 5m over water for 276m. Catalin Alexandru Duru flew over Lake Ouareau in Quebec, Canada, reaching 275.9m before the batteries ran out. “I wanted to showcase that a stable flight can be achieved on a hoverboard and a human could stand and control with their feet,” said Duru, after travelling five times the distance needed to set the Guinness World Record.

Yli tuhat osallistujaa sairastui vatsatautiin Ranskassa järjestetyn mutajuoksutapahtuman jälkeen, kertovat maan terveysviranomaiset.
Potilaiden oireina olivat muun muassa ripuli, oksennus ja kuume. Epidemian syynä pidetään sitä, että kisareitin mudan seassa oli eläinten ulostetta.
France's nuclear safety regulator told the BBC the flaw in the steel housing the reactor core at the nuclear plant being built in Normandy is "serious". He added that unless he was satisfied with the plans to put it right, he could stop the project. The fault in the French reactor is thought to be a construction fault, not an inherent weakness in the design.
The completion date for the Flamanville reactor in Normandy has already been shifted from 2012 to 2017 and the latest problem could make that worse. If they have to replace both the base of the reactor as well as the lid it could prove costly.
"If they would have to fabricate a new bottom and head and that is not going to be quick," said Steve Thomas, professor of energy policy at Greenwich University who has written extensively about the EPR delays. "Removing the base would be more time consuming and could be prohibitively expensive."
