Himalayan and other Asian glaciers put the brakes on Media playback is unsupported on your device Media captionAmaury Dehecq: "Knowing ice-flow speed allows us to better estimate glacier melt" The glaciers that flank the Himalayas and other high mountains in Asia are moving slower over time. Scientists have analysed nearly 20 years of satellite images to come to this conclusion. They show that the ice streams which have decelerated the most are the ones that have also thinned the most. The research has implications for the 800 million people in the region for whom the predictable meltwater from these glaciers is a key resource. The study is being presented at this week's American Geophysical Union (AGU) meeting in Washington DC - the world's largest annual gathering of Earth and space scientists. How was the research done?Led by the US space agency (Nasa), the assessment draws on one million pairs of pictures acquired by the Landsat-7 spacecraft between 2000 and 2017. Au..

'Surprise' Palu tsunami clue found on seafloor Image copyright Georgia Institute of Technology Image caption The tsunami came ashore within three minutes of the quake Scientists are getting closer to understanding the tsunami that struck Palu in Indonesia in September. Damaging waves rushed ashore after a Magnitude 7.8 quake, but researchers said at the time that they were surprised by their size. Now, a survey in the bay in front of the Sulawesi city shows significant subsidence of the seabed. This likely contributed to the abrupt displacement of water that then crashed ashore. More than 2,000 people lost their lives in the disaster. Preliminary results of various investigations are being reported here at the Fall Meeting of the American Geophysical Union - the largest annual gathering of Earth and space scientists. The quake occurred on what is called a strike-slip fault, where the ground on one side of a rupture moves horizontally past the ground on the other side. I..

Huawei Honor View20 and Samsung A8s have hole-punch cameras Image copyright Huawei Image caption The Honor View20 was shown off by Huawei's product manager, Jimmy Xiong, in Hong Kong Two smartphone-makers have unveiled handsets featuring a "hole-punch" selfie camera. The screens of the Samsung A8s and Huawei Honor View20 both feature a small circular space for the component. The design is intended to be less obtrusive than a "notch" - as popularised by Apple and later by many Android smartphone manufacturers. One expert said the innovation highlighted how competitive the market for mid-range devices had become. 'World first'Both Samsung and Huawei claimed to be first to launch the notchless camera design. The Chinese company may have slightly edged out its rival by unveiling its device at an event in Hong Kong a few hours before Samsung's launch. But the South Korean company had previously hinted at the screen-engineering feat by showing off a line drawing of the ..

China's new games censors take tough stance Image copyright Getty Images Image caption Video games have been linked to myopia and addiction in China A panel of censors set up to vet mobile video games in China has signalled it will be hard to please. State media reports that of the first 20 titles it assessed, nine were refused permission to go on sale. The Xinhua news agency added that developers of the other 11 had been told they had to make adjustments to remove "controversial content". There has been a clampdown on new video game releases in the country since March. The authorities have voiced concerns about the violent nature of some titles as well as worries about the activity being addictive. President Xi Jinping has also called for more to be done to tackle a rise in near-sightedness among the young - something that the country's ministry of education has linked to children playing video games at the cost of spending time on outdoor pastimes. It was announced in Augu..
