SEOUL: North Korean leader Kim Jong Un's promise to dismantle his country's only known nuclear test site has shone the spotlight on the secretive facility near the Chinese border. Sceptics have said the move to destroy North Korea's Punggye-ri test site is an empty concession by Kim Jong Un as the site may already be obsolete. (Photo: AFP/Jung Yeon-je) The Punggye-ri test site, located beneath a mountain in the country's northeast, hosted all six nuclear tests Pyongyang has conducted - most recently last September.

A Vietnamese high school senior has developed an augmented reality app that helps students with chemistry after she failed to gain entrance to a national chemistry competition. Chemoscope is the app designed by Tran Thi Anh Thu, a senior at Bao Loc High School for the Gifted in the Central Highlands province of Lam Dong. It won the fourth place prize for systems software and two special awards at the Intel International Science and Engineering Fair (ISEF) 2017, recently held from May 14 to 19 in California. “I was a chemistry major until I failed [to gain entrance] to a contest,” Thu said. “Now I’m seeking to ‘take revenge’ on that personal failure, as well as on a part of my youth that was dedicated to the wrong passion.” Visual learning Chemoscope helps visualize the teaching and learning of chemistry in high schools using augmented reality (AR) technology, which … [Read more...] about Vietnamese high school student creates AR chemistry app after academic flop
VietNamNet Bridge - The Hanoi authorities are trying to recall 2.5 million old motorbikes which discharge harmful substances to the environment. However, observers don’t think the solution is feasible. Reports all say that the motorbikes seriously pollute the air and harm people’s health. A survey of the HCMC University of Technology showed that the volume of fuel that motorbikes consume is 92 times higher than buses, while the average emission is four times higher than cars and 40 times higher than buses.The volume of fuel that motorbikes consume is 92 times higher than buses, while the average emission is four times higher than cars and 40 times higher than buses. Nguyen Minh Dong, director of Duc Viet Automobile Technology Consultancy, said every 100cc Euro 2 motorbike produces toxic emissions hundreds of times higher than a 1800cc Euro 5 car. Japanese scientists from Kanazawa University said motorbikes with old technology cannot burn up fuel and discharge toxic … [Read more...] about Hanoi vows to eliminate 2.5 million old, polluting motorbikes
VietNamNet Bridge - FPT is preparing for 4G trial, while Vietnamobile has announced it wants to join the 4G playing field. However, the telcos will have to wait until 2017 to attend the auction for the 4G 2.6GHz frequency band. The Ministry of Information and Communication (MIC) has said it will grant licenses to three largest mobile network operators – Viettel, MobiFone and VinaPhone – to provide 4G services on the 1800 MHz waveband. The waveband, in fact, has been allocated to them for the last 10 years to deploy 2G technology. According to the Radio Frequency Department, all telcos which want to have the right to use 2.6 GHz waveband will have to attend the auction, and only by 2017 will they be able to join auction for the waveband that MIC specifically reserves for 4G. Asked if Vietnamobile joins the 4G market, Elizabeth Fong, CEO of Vietnamobile, said Vietnamobile wants to obtain the license for 4G services and it is waiting for policies to be laid down by the … [Read more...] about Will FPT, Vietnamobile be able to catch the ‘4G train’?
