Touchscreen stop working while mobile plugged into a charging point in the train. Why ?

Mobile plugged into a charging point provided in the train, the battery started to charge up but the touchscreen stop working, if unplug it touchscreen will start working again. Why ?

Mobile adapters are almost always 'universal AC input', that is, they can work with input voltages anywhere from 85V-265V (RMS). So it likely has nothing to do with the fact that the train gives a lower supply of 110V. The issue has to do with conducted EMI because of the switching in the adapter. 

How capacitive touchscreen works: Basically, you have a transmitter and receiver electrode separated by a junction. A mutual capacitance links the electrodes, and the charge movement into Rx electrode is monitored to calculate this capacitance. When a finger is placed on the screen, it affects the fringing fields and hence causes a change in the mutual capacitance, hence causing a change in charge movement across junction. These changes in capacitance are measured across the matrix of Tx-Rx electrodes, to form a touch map.

How the adapter (charger) for phones is built: There is no earth connection in these chargers. It is isolated for safety, using a transformer. While the transformers physically isolates the secondary from the primary, there is a capacitance formed across the isolation between the windings. The topology of the charger is called as the flyback converter. Apart from the switching waveform, there is a great deal of high frequency resonant LC ringing in this topology. This switching EMI is coupled across the isolation because of the coupling capacitance (a capacitor couples high frequency very well). Since this appears as a common mode noise on the secondary side (i.e. it exists on both the DC power line and DC ground), there is no complete circuit path for this conducted EMI, so normally it causes no issues.

Now when you touch with your finger, there is a coupling capacitance formed from the display, through your body to 'earth'. The conducted EMI now has a complete circuit. Charge flow occurs from the Tx-Rx junction to the finger, and so the finger changes the measured capacitance. Not only this, the finger also has mutual capacitances linking to other Rx electrodes, which can cause charge flow changes at points where the finger isn't actually touching. The entire touch map gets screwed up, and the touchscreen behaves erratically.

China's race for space in the next decade

China: We will be on Mars by the end of 2020

China is aiming to own the race for space in the next decade, the country's space agency has said. China's ambitious and fast-growing space programme is targeting a landing on the dark side of the moon by 2018, and reaching Mars before the end of the decade, CNN reported. The country's space agency on Tuesday released a policy paper, and outlined the government's goals for exploring deep space. Wu Yanhua, deputy chief of the National Space Administration, said Beijing aims to launch its first Mars probe around 2020 to carry out orbiting and roving exploration, followed by a second mission that would include collection of surface samples from the red planet.  Wu said China's other plans include sending probes to Jupiter and its moons.

"Our overall goal is that, by around 2030, China will be among the major space powers of the world," he said. China was late to the space race -- it did not send its first satellite into space until 1970, just after the US put the first man on the moon. But in the decades since, China has pumped billions of dollars and other resources into research and training. Since 2003, China has staged a spacewalk, landed a rover on the moon and launched a space lab that it hopes paves the way for a 20-ton space station.

It has also sent five crews into space in the same span of time, making it only the third country in the world -- after Russia and the US -- to have such success. Wu said China was still studying the possibility of sending a man to the moon, but focusing on robotic lunar missions for now, including making the first soft landing on the far side of the moon around 2018. He also emphasised on China's increasing cooperation with other space agencies -- with NASA being the exception.

Since 2011, the US Congress has prohibited NASA from working with China because of national security concerns. During his campaign, US President-elect Donald Trump professed his love for NASA and that "space is terrific". His senior advisors have advocated a "new vision" for the US space programme.

"NASA should be focused primarily on deep space activities rather than Earth-centric work that is better handled by other agencies," wrote Robert Walker and Peter Navarro in October. "While the American government's space programme has suffered from under-investment, both China and Russia continue to move briskly forward with military-focused initiatives," they added.

"Each continues to develop weapons explicitly designed... to 'deny, degrade, deceive, disrupt, or destroy' America's eyes and ears in space." Chinese officials on Tuesday reiterated the country's "peaceful motives" behind its space exploration and utilisation, but many have pointed to Walker and Navarro's article as a sign that potential US-China collaboration in space would be unlikely -- and probably even more so after Trump's recent tweets challenging Beijing's polices on issues ranging from Taiwan to trade and South China Sea.

Face of 9,500-Year-Old Man

Researchers have reverse-engineered the ancient ritual practice that created one of the British Museum's most important artifacts—the Jericho Skull—revealing the face of a man whose remains were decorated and venerated some 9,500 years ago.

The Jericho Skull is also considered the oldest portrait in the museum's collection, and, until recently, its most enigmatic: a truncated human skull covered in worn plaster, with eye sockets set with simple sea shells that stare out blindly from its display case. Now, thanks to digital imaging, 3-D printing, and forensic reconstruction techniques, specialists have recreated the face of the individual inside the Jericho Skull—and it turns out to belong to a 40-something man with a broken nose.

An Unprecedented Discovery

The Jericho Skull is one of seven plastered and ornamented Neolithic skulls excavated by archaeologist Kathleen Kenyon in 1953 at the site of Tell es-Sultan, near the modern West Bank city of Jericho. The discovery—an archaeological sensation that brought Kenyon international fame—was first reported in National Geographic in December of that year.
"We realized with a thrill of discovery that we were looking at the portrait of a man who lived and died more than 7,000 years ago," Kenyon wrote, describing to Geographic readers the moment that the first skull was revealed. "No archeologist [sic] had even guessed at the existence of such a work of art."

While the seven skulls varied in detail, all had been originally stuffed with soil to support delicate facial bones before wet plaster was applied to create individualized facial features, such as ears, cheeks, and noses. Small marine shells represented eyes, and some skulls bore traces of paint.

Death of Facebook

The web users complain about the failure of Facebook

If you try to login to an online resource users receive an error message. Now the social network Twitter hashtag spreads #facebookdown, which means «Facebook collapsed." Members are divided into the most original thoughts on the incident. Some managed to blame the failure of the new US president Donald Trump. Other related incident with Friday the 13th. Some ironic that because of breakage Facebook users began to massively go to Twitter. Users often complain about the failures in the Facebook servers. In November 2016 the social network management by mistake put the memorial banners several dozen members.

“Facebook has a big problem”, the tech media breathlessly cries. Despite using it every day, I’m not a fan of Facebook, and so am drawn to these articles like a moth to a flame. Let’s all enjoy guilt-free schadenfreude at the expense of a billion-dollar business! So, what’s Facebook’s problem this week? People are sharing more web pages and news stories, but fewer “personal stories”—plain status updates that relate to their lives.
It turns out that Facebook’s controls for the news feed are pretty terrible. If a friend of mine comments on a non-friend’s post, “likes” it, or worst of all “reacts to” it, that’s automatically considered newsworthy for me. Facebook offers no way to customise the feed to remove these kind of posts. You can, however, choose to hide all posts from certain people, including those not on your friends list. So based on the advice I received, I started “hiding all from” everyone I didn’t recognise who appeared in my news feed. I’ve done this almost every day for the last couple of weeks, and in a way, it has been very successful. Almost all the strangers’ profile pic changes and distant events have gone, there’s fewer clickbait posts and memes, and mercifully almost no Minions at all.

A new spiral galaxy to solve space puzzles

This image was taken by Hubble Space Telescope few days back. It reveals the discovery of a new spiral galaxy. The spiral galaxy is known as RX J1140.1+0307. It is in the Virgo constellation, which presents an interesting puzzle.

NASA’s Hubble Space Telescope has yet again successfully discovered a new spiral galaxy. Scientists are trying to utilize this new galaxy to solve puzzles regarding space whereabouts. Hubble Space Telescope, ever since its launch has discovered beautiful galaxies and stars, and presented rare picture of space which kept scientists and the media awestruck. It was launched in 1990 and since then it has worked its parts out and changed our thinking about our Universe and Space. This image was taken by Hubble Space Telescope few days back. It reveals the discovery of a new spiral galaxy. The spiral galaxy is known as RX J1140.1+0307. It is in the Virgo constellation, which presents an interesting puzzle. NASA said that at first glance the galaxy looked quite similar to any other spiral galaxy that was seen earlier. But studies are being conducted and very soon this thinking might change.

NASA also added, “The Milky Way galaxy, like most large galaxies, has a super massive black hole at its center, but some galaxies are centered on lighter, intermediate-mass black holes. RX J1140.1+0307 are such a galaxy. In fact, it is centered on one of the lowest black hole masses known in any luminous galactic core.”  
Initially, when Hubble Space Telescope was launched, its rare view mirror collapsed a bit, which meant that it would send only, blurred images to earth. However, it was NASA’s first space skyrocket and they worked out the image mirror in 1993. The telescope has taken some iconic pictures of space which cannot be ignored. These pictures have helped scientists to find a lot about space. Hubble Space Telescope, during its space voyage has also let scientists know that there are 10 to the power 11 galaxies present in the space. It has successfully found some. It’s most recent discovery is the spiral galaxy.

The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore, Maryland, conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy in Washington, D.C. The telescope was launched in 1990 and since then it is the largest telescope in space. HST has helped scientists in exploring the deepest corners of the universe and has beamed back millions of stunning shots in its entire career. However, HST will be replaced by the James Webb Telescope in 2018 as it has thrice larger lens when compared to HST.

Donald Trump's CIA choice to be questioned

Washington - Donald Trump's pick to run the CIA faces a Senate confirmation hearing amid a testy standoff between the president-elect and the spy community. Trump has for the most part been dismissive of intelligence agencies' findings that Russia, specifically President Vladimir Putin, meddled in the 2016 U.S. election with the goal of electing Trump. The CIA is one of three main intelligence agencies that came to that conclusion. On Wednesday, Trump acknowledged Russia was responsible but speculated that intelligence agencies might have leaked to news organizations details about a classified briefing with him that included unsubstantiated allegations about his ties to Russia.

Pompeo graduated first in the Class of 1986 at the U.S. Military Academy at West Point. He served in the Army at a time when the Soviet Union was America's No. 1 adversary. Pompeo has been critical of the Obama administration's nuclear deal with Iran, which granted Tehran sanctions relief for rolling back its nuclear weapons program. And he has said that Muslim leaders are "potentially complicit" in terrorist attacks if they do not denounce those made in the name of Islam. He has also called for the government to increase surveillance to counter terrorists, not roll it back, and he wants Congress to play a larger role in overseeing intelligence agency activity. The congressman also supports the use of waterboarding to elicit information from suspected terrorists. Pompeo initially backed Sen. Marco Rubio, R-Fla., for the Republican nomination for president in 2016, but then promoted Trump's bid for the White House. Rubio is a member of the Senate intelligence committee.

China Launches Beijing-London Freight Train Route

A 200-container block train pulled out from the West Railway Station of Yiwu, in China’s coastal Zhejiang province, on Monday, January 2nd. Its destination was not nearby Shanghai, Beijing, or even the booming city of Chengdu in the west, but Barking — as in the London borough. This train, laden with clothes, bags, and household items, will make the 12,000 kilometer journey in 16 days, and symbolically usher in a new stage in China-UK trade relations.

This new rail route, which will traverse Kazakhstan, a part of Russia, Belarus, and the EU before entering the UK via the Channel Tunnel, is part of a rapidly growing network that now consists of 39 rail lines, which directly connect 16 cities in China with 15 cities in Europe. On Sunday, the Chinese government launched a rail freight service between China and London. This is the first direct rail link between China and Great Britain. The route of the service will traverse from Beijing, across Asia and Europe, before terminating in London.

Now, Beijing is aiming to resurrect this historic trade route by using rail power. The journey is as much an engineering challenge as a logistical problem. Freight must swap trains along the way, as railway gauges vary between the connecting countries. In its 18-day journey, freight will span 7,456 miles of railways, crossing Kazakhstan, Russia, Belarus, Poland, Germany, Belgium, France and the UK. The new route unlocks a new option for shippers. Currently, the choice is two-fold. One, take an ocean-bound route, which, although cheap, can be slow. Two, use an air carrier that is considerably faster, but much more expensive.

A direct rail link between Beijing and Western Europe enables manufacturers to explore new means to lower transport costs. The line may not provide a suitable alternative to all producers, but canny negotiators can leverage the new market entrant to lower prices of their established pathways by boat or plane.

China is reviving the historic Silk Road trade route that runs between its own borders and Europe. Announced in 2013 by President Xi Jinping, the idea is that two new trade corridors – one overland, the other by sea – will connect the country with its neighbours in the west: Central Asia, the Middle East and Europe.

The project has proved expensive and controversial. So why is China doing it?

There are strong commercial and geopolitical forces at play here, first among which is China’s vast industrial overcapacity – mainly in steel manufacturing and heavy equipment – for which the new trade route would serve as an outlet. As China’s domestic market slows down, opening new trade markets could go a long way towards keeping the national economy buoyant.

Hoping to lift the value of cross-border trade to $2.5 trillion within a decade, President Xi Jinping has channelled nearly $1 trillion of government money into the project. He’s also encouraging state-owned enterprises and financial institutions to invest in infrastructure and construction abroad.

“It is not an economic project, it is a geopolitical project — and it is very strategic,” Nadège Rolland, an analyst at the National Bureau for Asian Research, told He's not alone in suspecting China of a tactical repositioning in the global economy; it's clear that relationships with the ASEAN region, Central Asia and European countries stand to improve significantly if China directs more of its capital into developing infrastructure overseas.

Moreover, by striking up economic and cultural partnerships with other countries, China cements its status as a dominant player in world affairs.

"We will support the One Belt, One Road project," said President of the Asian Infrastructure Investment Bank, Jin Liquin. "But before we spend shareholders' money, which is really the taxpayers' money, we have three requirements." The new trade route should be promote growth, be socially acceptable and be environmentally friendly.

U.S. Support for the New Silk Road

The New Silk Road initiative was first envisioned in 2011 as a means for Afghanistan to integrate further into the region by resuming traditional trading routes and reconstructing significant infrastructure links broken by decades of conflict. Today, Afghanistan and its neighbors are leading the way in key areas, creating new North-South transit and trade routes that complement vibrant East-West connections across Eurasia. The region is reducing barriers to trade, investing in each other’s economies, and supporting international development and cross-border projects.

With multiple transitions underway in Afghanistan, the United States and its allies can bolster peace and stability in the region by supporting a transition to trade and helping open new markets connecting Afghanistan to Central Asia, Pakistan, India and beyond. Countries in the region know they have more to gain economically by working together than by being isolated. Promoting connectivity in a region that is the least-economically integrated in the world is challenging, but the benefits can be transformative. This is why the United States is promoting the New Silk Road initiative linking Central and South Asia in four key areas:

Regional Energy Markets: With a population of more than 1.6 billion people, South Asia’s economies are growing rapidly, and South Asia’s demand for inexpensive, efficient, and reliable energy is growing in turn. At the same time, Central Asia is a repository of vast energy resources – including oil, gas, and hydropower. Directing some of these resources southward from Central to South Asia, through Afghanistan, would be a win-win for the region’s energy suppliers and energy users alike.  

Trade and Transport:
Improving trade and transit in South and Central Asia means improving the “hardware” of reliable roads, railways, bridges, and border crossing facilities. But it also means working on the “software” side, harmonizing national customs systems, bringing states into multilateral trade institutions, and getting neighbors to work together to break down institutional and bureaucratic barriers to trade. 

Businesses and People-to-People: Regional economic connectivity is more than infrastructure, border crossings, and the movement of goods and services. Sharing ideas and expansion of economic markets also creates opportunities for youth, women, and minorities and enhances regional stability and prosperity.

Discovered in 1852 by Italian astronomer Annibale de Gasparis, Psyche is one of the ten most massive asteroids in the asteroid belt. Although Psyche is thought to be a world made of metal, scientists have recently found the presence of water on this minor planet. The new findings, which baffled researchers, could be confirmed and further studied by a newly-announced NASA mission – Psyche.

Psyche is an irregularly-shaped M-type asteroid with a diameter of about 124 miles (200 kilometers). Several studies conducted over the last decade suggest that this celestial body is primarily composed of metal and that it has a surface which is also rich in metals. However, recent research carried out by a team of scientists led by Driss Takir of the U.S. Geological Survey (USGS) adds a mystery to our understanding of this small rocky world.

Researchers observed Psyche with the SpeX spectrograph located at NASA’s Infrared Telescope Facility (IRTF) in Hawaii. They were searching for evidence of hydration on the asteroid. Scientists discovered that Psyche’s spectra exhibited a 3-micron absorption feature, possibly due to water or possibly hydroxyl.

The new findings suggest that Psyche might not have a metallic core and could actually be a water-rich asteroid. This left a most perplexing question, What is the origin of the water on this rocky world? Takir’s team offers few plausible explanations for this phenomenon.

“It is possible that water-rich minerals detected on Psyche might have been delivered to its surface by carbonaceous asteroids that impacted Psyche in the distant past. We also think that Psyche, and some other M-type asteroids, may not be entirely exposed metallic core. What we see might instead have been a core-mantle boundary of a differentiated body that was disrupted via impacts. Solar wind could be another mechanism that can produce hydroxyl by interacting with the surface of Psyche and some other M-type asteroids,” Takir told

Although IRTF is one of the most optimized and suitable telescopes for detecting water and hydroxyl on the surface of asteroids, it could never replace a scientific probe examining its target in situ (on site). That is why sending a dedicated spacecraft equipped with a set of specialized instruments should allow the scientists to better characterize hydration on the surface of Psyche and solve the mystery of the origin of its water.

Such a dedicated mission to Psyche is in its early stages of development as NASA has announced on Jan. 4 that it will send a probe to this asteroid under the agency’s Discovery Program. The “Psyche” spacecraft is slated to be launched in 2023 and expected to arrive at its destination in 2030. If everything goes as planned, the mission would spend 20 months in orbit around the asteroid, mapping it and studying its properties.

While the spacecraft’s primary goals will be to determine whether Psyche really is a protoplanetary core, how old it is, and what its surface is like – it could be used to confirm the findings presented by Takir’s team and unveil the mechanism behind the hydration of this small world.

In order to perform its scientific studies, instruments have been proposed that would be carried on the orbiter. It could potentially be equipped with a multispectral imager capable of acquiring high-resolution images using filters to discriminate between the asteroid’s metallic and silicate constituents. Another tool would be a gamma-ray and neutron spectrometer that would detect, measure, and map Psyche’s elemental composition. Moreover, the probe could also be fitted with a magnetometer designed to detect and measure the asteroid’s remnant magnetic field.

Meanwhile, until the newly-announced spacecraft reaches Psyche, Takir’s research team will focus on studying other water-rich asteroids using ground-based instruments and their own techniques of observations.

“We will continue studying Psyche, and other water-rich asteroids, to give us further insight into the formation and evolution of the solar system. Although detecting water is very challenging using ground-based telescopes, we developed some observing tools and data reduction techniques that allow us to characterize the shape of the 3-micron absorption hydration band in asteroids,” Takir concluded.

Nokia 6


HMD has now come out with the Nokia 6, the first Android-powered smartphone carrying the brand after purchasing it from Microsoft. It starts shipping in China early this year.  ( Nokia ).

Now, HMD Global has announced the Nokia 6, the first smartphone to be released carrying the brand since its purchase of the company. The handset, however, is targeted mainly for users in China. Scurrying back to the smartphone race is Nokia, after a somewhat strained stint under the ownership of Microsoft. That deal spewed competition-ready Lumia phones, but when that didn't become as profitable as Microsoft would've liked, it sold Nokia's mobile assets to HMD Global, a Finnish company founded specifically to reinvigorate the Nokia brand.

"The Nokia 6 is a result of listening to our consumers who desire a beautifully crafted handset with exceptional durability, entertainment and display features," said Arto Nummela, HMD Global's CEO. The Nokia 6 features an all-aluminum design, and HMD Global says that the phone undergoes an anodizing process that takes over 10 hours to complete, resulting in an "aluminium unibody with the highest level of visual and structural quality."

The Nokia 6 is the first Nokia smartphone made by HMD to ever come with Android, and the latest version at that, having been confirmed to ship with Nougat. Unlike previous Windows-powered Lumia smartphones, the Nokia 6 can readily tap into the expansive ecosystem offered by Android, which translates to a platform filled to the brim with apps.
Looking at the specs, it's pretty clear that the smartphone is poised to be a mid-range offering. There's a 5.5-inch screen at 1080p that's layered by 2.5D Gorilla Glass protection. On the back is a 16-megapixel camera, and on the front shooter is an 8-megapixel camera.
The phone has 4 GB of RAM and 64 GB of internal storage. Under the hood is a Qualcomm Snapdragon 430 with X6 LTE modem which HMD says is designed for excellent battery life and graphics performance.

These specs surely don't suggest a phone that's housing powerhouse internals, although the handset should fare well against similarly priced mid-range entries in the Chinese market.

The Nokia 6 will retail for CNY 1,699, around $245. It starts shipping in China early this year through online retailer Nokia had once dominated the smartphone market back when it wasn't too saturated with field players. As the arena became more competitive, it slowly lost a firm foothold in the business. It tried to regain some footing with the Lumia handsets, but those didn't catch on. After Microsoft abandoned Nokia's smartphone business, HMD took over. In December, the company struck a licensing deal that gave it sole use of the Nokia branding on all future phones and tablets it'll manufacture. HMD is paying Nokia for the brand and patents, although the eponymous phone maker isn't directly involved with HMD, according to Reuters. Nokia is now more focused on its network equipment business.
HMD launched basic Nokia phones in December. The company says that it plans to launch more products on the first half of the year. 

USD 18.8 million Gravitational waves observatory

China is working to set up the world's highest altitude gravitational wave telescopes in Tibet Autonomous Region to detect the faintest echoes resonating from the universe, which may reveal more about the Big Bang. Construction has started for the first telescope, code-named Ngari No.1, 30 km south of Shiquanhe Town in Ngari Prefecture, said Yao Yongqiang, chief researcher with the National Astronomical Observatories of the Chinese Academy of Sciences.

The telescope, located 5,250 meters above sea level, will detect and gather precise data on primordial gravitational waves in the Northern Hemisphere. It is expected to be operational by 2021. Yao said the second phase involves a series of telescopes, code-named Ngari No. 2, to be located about 6,000 meters above sea level. He did not give a time frame for construction of Ngari No. 2. The budget for the two-phase Ngari gravitational wave observatory is an estimated 130 million yuan (18.8 million U.S. dollars). The project was initiated by the Institute of High Energy Physics, National Astronomical Observatories, and Shanghai Institute of Microsystem and Information Technology, among others. Ngari, with its high altitude, clear sky, and minimal human activity, is said to be one of the world's best spots to detect tiny twists in cosmic light. Yao said the Ngari observatory will be among the world's top primordial gravitational wave observation bases, alongside the South Pole Telescope and the facility in Chile's Atacama Desert. Gravitational waves were first proposed by Albert Einstein's theory of general relativity 100 years ago, but it wasn't until 2016 that scientists with the Laser Interferometer Gravitational-Wave Observatory announced proof of the waves' existence, spurring fresh research interest among the world's scientists. China has announced its own gravitational wave research plans, which include the launch of satellites and setting up FAST, a 500-meter aperture spherical radio telescope in southwest China's Guizhou Province.
