China is ready to put on the "ear phones" and flip the "ON" switch for the world's largest, most powerful radio telescope, that is nearing completion in a vast, bowl-shaped valley in the mountainous southwestern province of Guizhou by the end of September, accompanied by regulations to protect the facility. Its unrivaled precision will allow astronomers to survey the Milky Way and other galaxies and detect faint pulsars, and work as a powerful ground station for future space missions.
"A radio telescope is like a sensitive ear, listening to tell meaningful radio messages from white noise in the universe," said Nan Rendong, chief scientist of the FAST project. He told Xinhua that the huge dish will enable much more accurate detection. "It is like identifying the sound of cicadas in a thunderstorm."
"Having a more sensitive telescope, we can receive weaker and more distant radio messages," Wu Xiangping, director-general of the Chinese Astronomical Society, "It will help us to search for intelligent life outside of the galaxy and explore the origins of the universe," he added underscoring the China's race to be the first nation to discover the existence of an advanced alien civilization.
The construction of the Five-hundred-meter Aperture Spherical Telescope, or FAST, has entered its final phase. With a dish the size of 30 football fields, FAST, which measures 500 meters in diameter, dwarfs Puerto Rico's 300-meter Arecibo Observatory. Under the regulation, FAST requires radio silence within a 10-kilometer radius.
The Chinese government hopes that a more subtle benefit of the behemoth eye on the cosmos will entice some of the some of the brightest minds in science or astronomy studying abroad to return home to China. China is the leading nation in the world in the number of students it sends students abroad, especially for majors such as science or engineering.
FAST is the world's largest single-aperture telescope, overtaking the Arecibo Observatory in the US territory of Puerto Rico, which is 305 meters (1000 feet) in diameter. The dish will have a perimeter of about 1.6 kilometers, Xinhua said, and there are no towns within five kilometers, giving it ideal surroundings to listen for signals from space.
According to chief scientist from China's National Astronomical Observations, Li Di, FAST will be able to scan up to twice more areas of the sky than Arecibo shown above, and it will have between three to five times the sensitivity. It's in their hopes that if there is indeed alien life, this gargantuan will find it.
The region's karst topography -- a landscape of porous rock fissured with deep crevasses and underground caves and streams -- is ideal for draining rainwater and protecting the reflector. Unfortuately, citizens actually living in the area where the radio telescope will be built are being relocated. Some 2,000 families residing near the Pingtang and Luodian counties will be given $1,800 per individual for the forced relocation.
For years Chinese scientists have relied on "second hand" data collected by others in their research and the new telescope is expected to "greatly enhance" the country's capacity to observe outer space, Xinhua said. Beijing is accelerating its military-run multi-billion-dollar space exploration program, which it sees as a symbol of the country's progress. It has plans for a permanent orbiting station by 2020 and eventually to send a human to the moon.
Construction on the telescope started in March 2011.

On July 17, 2016, a huge stream of ice and rock tumbled down a narrow valley in the Aru Range of Tibet. When the ice stopped moving, it had spread a pile of debris that was up to 30 meters (98 feet) thick across 10 square kilometers (4 square miles). The massive debris field makes this one of the largest ice avalanches ever recorded. The only event of a comparable size was a 2002 avalanche from Kolka Glacier in in the Caucasus , explained Andreas Kääb, a glaciologist at the University of Oslo.
The cause of the avalanche is unclear. "This is new territory scientifically," said Kääb. "It is unknown why an entire glacier tongue would shear off like this. We would not have thought this was even possible before Kolka happened." Nine people, 350 sheep, and 110 yaks in the remote village of Dungru were killed during the avalanche.
Kääb's preliminary analysis of satellite imagery indicates that the glacier showed signs of change weeks before the avalanche happened. Normally, such signs would be clues the glacier might be in the process of surging, but surging glaciers typically flow at a fairly slow rate rather than collapsing violently in an avalanche.
After inspecting the satellite imagery, University of Arizona glaciologist Jeffrey Kargel agreed that a surging glacier could not be the cause. "The form is completely wrong," he said. "It must be a high-energy mass flow. Maybe liquid water lubrication at the base played some role," he said.
Tian Lide, a glaciologist at the Chinese Academy of Sciences, visited the site in August and described the avalanche as "baffling" because the area where the ice collapse began is rather flat. "We failed to reach the upper part of the glacier for safety reasons," he said in an email, "but we will go the upper part [later] to see if we can find some more hints about what caused the glacier disaster."

New research by the University of Surrey published today in the journal Monthly Notices of the Royal Astronomical Society has shone light on a globular cluster of stars that could host several hundred black holes, a phenomenon that until recently was thought impossible.
Globular clusters are spherical collections of stars which orbit around a galactic centre such as our Milky-way galaxy. Using advanced computer simulations, the team at the University of Surrey were able to see the un-see-able by mapping a globular cluster known as NGC 6101, from which the existence of black holes within the system was deduced.
These black holes are a few times larger than the Sun, and form in the gravitational collapse of massive stars at the end of their lives. It was previously thought that these black holes would almost all be expelled from their parent cluster due to the effects of supernova explosion, during the death of a star.
"Due to their nature, black holes are impossible to see with a telescope, because no photons can escape", explained lead author Miklos Peuten of the University of Surrey. "In order to find them we look for their gravitational effect on their surroundings. Using observations and simulations we are able to spot the distinctive clues to their whereabouts and therefore effectively 'see' the un-seeable".
It is only as recently as 2013 that astrophysicists found individual black holes in globular clusters via rare phenomena in which a companion star donates material to the black hole. This work, which was supported by the European Research Council (ERC), has shown that in NGC 6101 there could be several hundred black holes, overturning old theories as to how black holes form.
Co-author Professor Mark Gieles, University of Surrey continued, "Our work is intended to help answer fundamental questions related to dynamics of stars and black holes, and the recently observed gravitational waves. These are emitted when two black holes merge, and if our interpretation is right, the cores of some globular clusters may be where black hole mergers take place."
The researchers chose to map this particular ancient globular cluster due to its recently found distinctive makeup, which suggested that it could be different to other clusters. Compared to other globular clusters NGC 6101 appears dynamically young in contrast to the ages of the individual stars. Also the cluster appears inflated, with the core being under-populated by observable stars.
Using computer simulation, the team recreated every individual star and black hole in the cluster and their behavior. Over the whole lifetime of thirteen billion years the simulation demonstrated how NGC 6101 has evolved. It was possible to see the effects of large numbers of black holes on the visible stars, and to reproduce what was observed for NGC6101. From this, the researchers showed that the unexplainable dynamical apparent youth is an effect of the large black hole population.
"This research is exciting as we were able to theoretically observe the spectacle of an entire population of black holes using computer simulations. The results show that globular clusters like NGC 6101, which were always considered boring are in fact the most interesting ones, possibly each harboring hundreds of black holes. This will help us to find more black holes in other globular clusters in the Universe. " concluded Peuten.

Anyone in their right mind would want to move out. Among other problems, the property has leaking roofs, hidden pockets of asbestos, clear fire risks, vulnerability to flooding, and mice. The annual repair bill runs to around £50m. It is also routinely overheated, chintzily furnished and home to an aroma that often suggests last week's school dinners. Small wonder that, since 2012, some of the Palace of Westminster's occupants have been loudly fretting about the place's upkeep.

Continue reading...Artist David Shrigley has released a series of 30 designs for Danish retail chain, Flying Tiger Copenhagen.
Formerly known as Tiger, the brand commissioned Shrigley to design a number of products based on the theme of Strong Messages, featuring his trademark humorous drawings and messages.
The collection includes a set of drawing pencils covered in messages scrawled in Shrigley's own handwriting; including “words are boring”, “make art not friends” and “I'm illiterate”.
The words “Coloured pencils for making nice drawings of cats, flowers, etc.” feature on a specially designed pencil case that is also adorned with a drawing of a cat.
Phone and tablet cases include the instruction “kill the computer”, and other products such as shower curtains, trays, socks and bags are all adorned with artworks by Shrigley.
The artist has also released a miniature version of his Really Good statue, which is set to be unveiled at The Fourth Plinth in London later this month.
Concept developer at Flying Tiger Copenhagen, Mai Due Brinch, says: “We want to make art more accessible by making it a part of people's everyday life. Shrigley's works are humorous, dark, delightfully absurd and bizarre, and the emphasis is on the message rather than on technique.”
The post Tiger releases stationery range designed by David Shrigley appeared first on Design Week.

My organization, Adventure Scientists, enlists the help of adventurers around the world to collect water samples for our Global Microplastics Initiative. This May, Microplastic Adventure Scientists Gerrit Egnew and Kirra Paulus embarked on a month-long expedition to sample and paddle 30 rivers in 30 days. Their resulting video and story are a call to action to paddlers everywhere to help protect the rivers that give them so much. Words by Gerrit Egnew.
30 Days 30 Rivers from Kirra Kirra on Vimeo.
George and I looked upstream at Skyscraper, a rapid halfway down South Silver Creek, in the mountains near Placerville, CA. Beneath us was an undercut cave; we had been there for a while, scouting and fretting and rationalizing. Kirra scrambled down to us and asked if we planned to run it. I looked at George: “I sure wish someone would come down from behind us and, like, run it. Or set safety. So that we know it's okay.”
Ten minutes later, as we walked back to our boats, a group of six Kiwis materialized from the white roar. “Want to set safety with us on the Teacups?” one asked. Providence.
Unfortunately, this close community is sometimes insular. (When your activity is the coolest ever, what else matters?) But there is such vivid, exultant energy in the kayaking community; how can it be directed to tangible issues? Kayakers are driven to explore, travel, and experience new rivers, but what do we do to help conserve them?
Adventure Scientists has a compelling solution. Gregg Treinish, founder of Adventure Scientists, realized that scientific research requires travel in extreme or inaccessible environments and training researchers to manage these situations safely is time-consuming and expensive. But there is already a group of people in these environments: outdoor sports enthusiasts. Particularly, kayakers travel worldwide to remote creeks and rivers. Adventure Scientists' Microplastics project organizes kayakers and other adventurers to take water samples wherever they may be in the world. Researchers can get much more data by partnering with people who already have the skills and motivation to get into the places being studied.
Kirra graduated in the spring, and I'm taking time off. We both river guide and had been planning a trip in May before rafting season started. Influenced by Adventure Scientists, that trip suddenly seemed like an opportunity to gather data for the Global Microplastics Initiative. We had a month. Well, we had to take finals in the first week of May. So, a month minus five days of caffeinated stress. That's kind of like thirty days. (Although May has thirty-one; I haven't taken calculus in a year.)
First, right before finals, we jetted to the Lochsa Rendezvous. Then after our last exam, Kirra and I got on the road. Over the next few weeks, in a haze of exhaustion, river noise, shuttle complications, and Cold Snacks, we kayaked and sampled the following rivers:
Joining us for various sections were George Milheim, Kathryn Egnew, Bridger Dunnagan, Mark Rockwell, Spencer Lawley, and Jessie Bohn. The trip was less about paddling stouts (although we scared ourselves more than once) and more about going to new places. We wanted to expand our experience of the river world and add to its scientific knowledge base. Adventure and science need not be mutually exclusive. Small groups of citizen scientists, operating in areas they know well, can do powerful work for environmental science. We've become activate and engaged in our community on a new level. You can too.
