A private company located in eastern China has printed ten full-size houses using a huge 3D printer in the space of a day. The process utilizes quick-drying cement, but the creators are being careful not to reveal the secrets of the technology.

China’s WinSun company, used a system of four 10 meter wide by 6.6 meter high printers with multi-directional sprays to create the houses. Cement and construction waste was used to build the walls layer-by-layer, state news agency Xinhua reported.

“To obtain natural stone, we have to employ miners, dig up blocks of stone and saw them into pieces. This badly damages the environment,” stated Ma Yihe, the inventor of the printers. Yihe has been designing 3D printers for 12 years and believes his process to be both environmentally friendly and cost-effective.

Upsalite, ‘Impossible’ Material Believed To Have Many Uses, Created In Swedish Lab

Posted by Ram Kumar Shrestha on August 7, 2013

It doesn’t look like much, but scientists from Sweden’s Uppsala University are calling a newly created form ofmagnesium carbonate an “impossible” material.

Dubbed upsalite, the highly porous material sets new records for surface area and water absorption, according to a written statement issued by the university. It is expected to have all sorts of applications, from controlling moisture in processes used by the electronics and pharmaceutical industries to sopping up toxins in the aftermath of chemical and oil spills.

“In contrast to what has been claimed for more than 100 years in the scientific literature, we have found that amorphous magnesium carbonate can be made in a very simple, low-temperature process,” study co-author Johan Goméz de la Torre, a researcher in the university’s nanotechnology and functional materials division, said in the statement.

The researchers succeeded in making upsalite in 2011 by bubbling carbon dioxide through an alcohol-containing suspension. But it took another year of analysis and fine-tuning to be sure that they had created the “impossible” material.

Upsalite has the highest surface area ever measured for a so-called alkali earth metal carbonate, according to the statement. In addition, it’s filled with empty pores with diameters measuring less than 10 nanometers. Read the rest of this entry »

Rijan’s Theory to Glorify Nepal with his Scientific Achievements

Posted by Ram Kumar Shrestha on April 24, 2013

Karki, who is inspired by Newton’s theory, succeeded in securing the Student Achievement Award (SAA) by presenting his theory on operating a railway in the mountains without electricity or any fuel in an energy conference organized in the USA.
The fund has provided him 1‚200 US dollars annually for four years. With a plan to study physics in the future‚ he is now studying at B. Sc. first year in applied physics in a university.

Rijan KarkiNepal’s youth scientist Rijan Karki has done a quite praiseworthy deed by glorifying Nepal at the US space centre, National Aeronautics and Space Administration (NASA).

Karki, who is inspired by Newton’s theory, succeeded in securing the Student Achievement Award (SAA) by presenting his theory on operating a railway in the mountains without electricity or any fuel in an energy conference organized in the USA.

Karki, who was successful in presenting his talent in the world arena by being active with special interest in the sector of science and technology, has recently received a Rs. 25,101-amount cash prize entitled ‘Sami Youth Encouragement Award- 2069 BS.’

Rijan won the International Student Achievement Award at the age of 16 from the US space centre NASA in 2009. He had presented a working paper at NASA about the laws of gravitation and flabbergasted the participating scientists.

Nurturing a dream of becoming a doctor or engineer while he studied at Class 6, he is on his way to success of becoming a famous youth scientist, and researcher after he was attracted to Newton’s theories.

Karki, who has put several national level awards under his belt, plans to stay in Nepal itself and do something worthwhile in future. Karki, who is engaged in researches of inventions like ‘bouncing car’ and ‘RK’s Simple Machine’ named after himself (which can help push anything weighty and stores energy) , has been arguing that substances like water ,soil and rocks can be used as fuel.

The young Nepali boy, who succeeded in winning the prestigious Student Achievement Award from USA by using simple materials around us scientifically, had only passed Ten Plus 2 level from Nobel Academy, Baneshwor, after school education from the Budhanilkantha of Kathmandu.

Karki is now studying at Kathmandu University (KU) with assistance from a Nepali organization and the Wells Mountain Fund of USA.  Read the rest of this entry »

Victoria Planning Minister Approves Tallest Building in Southern Hemisphere

Posted by Ram Kumar Shrestha on March 21, 2013

In an historic day for the Victorian development industry, planning minister Matthew Guy has approved a 108-storey apartment and hotel tower in Melbourne’s CBD – the tallest ever proposed in the city.

The proposed tower, known as Australia 108, will feature 664 apartments and 288 rooms in a six star hotel, and soar 388 metres above ground level, giving it the title of the tallest building in the southern hemisphere. If delivered, Australia 108 will eclipse Melbourne’s Eureka Tower and the Gold Coast’s Q1 buildings.

Australia108 - 1

Minister Guy, who came under scrutiny during the planning process due to claims the building would overshadow the Shrine of Remembrance, issued a press release later hailing the proposed development.

“I am proud to approve a tower that will define our city for many years to come and which I am sure will become as iconic a Melbourne landmark as Flinders Street Station or Federation Square,” he said.

“The Australia 108 mixed-use tower will be an icon both visually and for those who will live in it, stay at its hotel, dine at the level 84 Sky Lounge or visit the level 108 Star Bar.

“Towers such as Australia 108 are consistent with the Coalition Government’s drive to concentrate high-density development in defined areas and out of existing, quiet neighbourhoods.

“Every apartment in this tower is one less apartment in an existing quiet neighbourhood.”

Australia108 - 2

According to The Age, a consortium of private investors including Nonda Katsalidis, Benni Aroni, Adrian Valmorbida, Ian Fayman, Gary Caulfield and Mark Hopkinson are behind the development of the project.

The $600m tower will feature one bedroom apartments on Levels 12-39 and 41-65 priced from $425,000 and two bedroom apartments from $575,000.

A selection of three bedroom apartments will be available from levels 66-78 from $775,000 along with an exclusive offering of penthouse apartments.

It has also been revealed that the 388 metre tower will use prefabricated structural sections developed by Nonda Katsalidis’ construction company to deliver the tower in record time. Read the rest of this entry »

Human intelligence is declining according to Stanford geneticist

Posted by Ram Kumar Shrestha on February 20, 2013

afp-eisele-photo-johannes.nEver can’t help but think you’re surrounded by idiots? A leading scientist at Stanford University thinks he has the answer, and the bad news is things aren’t likely to get any better.

Dr. Gerald Crabtree, a geneticist at Stanford, has published a study that he conducted to try and identify the progression of modern man’s intelligence. As it turns out, however, Dr. Crabtree’s research led him to believe that the collective mind of mankind has been on more or a less a downhill trajectory for quite some time.

According to his research, published in two parts starting with last year’s ‘Our fragile intellect. Part I,’ Dr. Crabtree thinks unavoidable changes in the genetic make-up coupled with modern technological advances has left humans, well, kind of stupid. He has recently published his follow-up analysis, and in it explains that of the roughly 5,000 genes he considered the basis for human intelligence, a number of mutations over the years has forced modern man to be only a portion as bright as his ancestors.

“New developments in genetics, anthropology and neurobiology predict that a very large number of genes underlie our intellectual and emotional abilities, making these abilities genetically surprisingly fragile,” he writes in part one of his research. “Analysis of human mutation rates and the number of genes required for human intellectual and emotional fitness indicates that we are almost certainly losing these abilities,” he adds in his latest report.

From there, the doctor goes on to explain that general mutations over the last few thousand years have left mankind increasingly unable to cope with certain situations that perhaps our ancestors would be more adapted to. Read the rest of this entry »

The Biggest Scientific Breakthroughs of 2012

Posted by Ram Kumar Shrestha on February 17, 2013

Robert T. Gonzalez and Annalee Newitz

This was an incredible year for science and engineering. We sent a powerful robot scientist to Mars, and we discovered the elusive Higgs Boson particle, plus there were world-changing innovations in medicine and materials science. We sequenced the genome of a human ancestor, and looked into the mind of an artificial intelligence that recognized the content of images on the web for the first time (of course it included cat faces). Here are the seventeen biggest scientific breakthroughs of 2012.

 The Biggest Scientific Breakthroughs of 2012

NASA’s Curiosity Rover Lands on Mars

NASA’s one-ton, six-wheel-drive, nuclear-powered science laboratory — aka Curiosity —touched down on the surface of Mars in early August, following an eight-month voyage across millions of miles of space. It is far and away the biggest and most scientifically capable rover ever sent to another planet. The landing sequence, alone, which required lowering the rover to the surface of the planet from a hovering, rocket-powered sky crane, was the most technically impressive ever attempted, and played out beautifully.

Today, just five months into Curiosity‘s two-year primary mission, the rover is still just stretching its legs, but has already made several intriguing discoveries. In the months to come, the rover will begin poring over the pages of Mars’ history, as it scans the layers of sedimentary rock comprising Mount Sharp in search of signs of whether the planet can, or ever could, support life.

 The Biggest Scientific Breakthroughs of 2012

Artificial DNA Brings Us Closer Than Ever to Synthesizing Entirely New Forms of Life

Synthetic biologists demonstrated that artificial nucleic acids known as “XNAs” can replicate and evolve just like DNA and RNA, and are even more resistant to degradation than the real thing. The implications of evolvable, artificial genetic information are vast, to put it lightly, and stand to affect everything from genetic research to the search for alien life, to the creation of an entirely synthetic, alternative life form.

Richard III’s Face Reconstructed From English King’s Skull (VIDEO)

Posted by Ram Kumar Shrestha on February 6, 2013

 By 

Now that Richard III’s remains have been identified “beyond a reasonable doubt,”scientists are trying to figure out what the English king looked like.

DNA tests and other techniques confirmed that a battle-scarred skeleton found buried in ruins beneath a parking lot in Leicester, England was that of the monarch, researchers announced on Feb. 4. Now, with the help of technology developed for criminal investigations, scientists at Scotland’s Dundee University have created a bust of Richard, who died in battle in 1485.

king richard face

The bust reveals a king subtly different from the one depicted in familiar portraits, which show a hunched shoulder, claw-like hands and squinting eyes. AlthoughRichard’s skeleton does show a spinal curvature, historians say the popular image of the king was likely exaggerated by his enemies. Read the rest of this entry »

Engineers Australia Wants Flood Class Action Information to be Made Available

Posted by Ram Kumar Shrestha on February 2, 2013

Queensland Flood

If the class action lawsuit over the Queensland floods proceeds following the devastating damage caused in 2011, then Engineers Australia wants the information surrounding the action to be made freely available.

An independent investigation has concluded that the flooding of a large number of properties down river from Wivenhoe Dam in 2011 would not have occurred had the dam’s operations been up to the standards expected of a reasonably competent dam operator.

Comprehensive modelling will form the basis of a class action lawsuit on behalf of thousands of flood victims in Queensland’s southeast. The modelling will be run on a no-win no-fee basis by Maurice Blackburn Lawyers and backed by litigation funder IMF Australia.

Maurice Blackburn Class Actions principal Damian Scattini said there is sufficient evidence to ensure a class action could proceed.

“Our modelling shows that had Wivenhoe been operated properly there would not have been flooding in some areas,” he said. “In other areas this poor operation meant flooding was much worse than it should have been. This evidence provides us with strong grounds to proceed with a class action.”

Hell and the heavens

Scientists plan visits to the darkest deeps and the starriest skies

stairway-to-brand-heaven-and-hellTwo of 2013’s most exciting scientific projects share an astonishing technological sophistication but set off for destinations that could hardly be more different. One, HADES, will send the robot submersible Nereus 10km (6 miles) down beneath the sea to survey the strange life forms found in the sunless abyss of one of the Earth’s deepest ocean trenches. The other, Gaia, will launch a satellite equipped with a powerful pair of telescopes 1.5m kilometres up into the heavens to chart a billion stars of the Milky Way.

First off will be HADES (Hadal Ecosystems Studies Programme), which in March will begin exploring the 10km-deep Kermadec trench off New Zealand. Despite pressures 1,000 times greater than at the surface, the submersible will find plenty to see. Alan Jamieson, a marine biologist from the University of Aberdeen and one of the HADES leaders, has already sent “landers” down deep trenches around the world. Each is a ballasted metal tripod carrying cameras and bait to attract animals. Seven kilometres down, Dr Jamieson has found “supergiant” amphipods, related to the sand hoppers common on the seashore but, at 30cm long, 20 times bigger. Deeper still, hordes of smaller amphipods scurry about in the blackness. “At 10km they turn up in thousands and just devour anything. They look like a swarm of bees,” Dr Jamieson sa Read the rest of this entry »

UFO Sightings At International Space Station On The Rise (And You Can Help Find Them) (VIDEO)

Posted by Ram Kumar Shrestha on January 14, 2013

By Lee Speigel

As 2012 ended and 2013 began, numerous UFOs were reported around the country — nothing earthshattering there — but what about alleged unidentified objects seen in space near the International Space Station (or ISS), a couple of hundred miles above Earth?

Videos have cropped up on YouTube showing images taken by NASA cameras of objects of different shapes, some moving very slowly, others rapidly hurtling through space.

What, exactly, are we looking at here? Alien spacecraft dropping by for a visit with the ISS? Reflections from ISS windows? Meteors? Or various types of orbiting or fast moving spacecraft-generated debris?

On Christmas Day, YouTube poster Streetcap1 recorded video of a silvery object, moving slowly near the curvature of Earth. At :46 into the following video, the object can be seen in faraway perspective.
