Week night - 2016 Rio Olympics

1 Rio 2016: Nikki Hamblin and Abbey D'Agostino given 'fair play' Olympic award for show of sportsmanship



Nikki Hamblin or Abbey D’Agostino did not win gold, silver or bronze in their respected event but instead have been presented with the Fair Play award, the only award of its type this Olympics.The pair made headlines around the world and were heralded for capturing the “Olympic spirit” when competing in the qualifying heat for the 5,000 metres last week.With 2,000 metres left to go, New Zealand athlete Hamblin tripped and fell, accidentally tripping up the USA’s D’Agostino too. The American soon got up and instead of running helped Hamblin before faltering on a clearly injured foot. D’Agostino later fell down again and so Hamblin helped her up and the two began to run the race together before embracing at the finish line.
The Fair Play Committee, supported by the International Olympic Committee (IOC), said the pair have received the award for their acts of “selflessness and exemplary sportsmanship”.

Week eight - Samsung Galaxy note 7 explosion

Here's why Samsung Galaxy Note 7 phones are catching fire

The Samsung Galaxy Note 7 could explode.

How could this have happened? Simple: your phone is a Samsung Galaxy Note 7 - and it's one of over a hundred that have spontaneously burst into flames.
After 35 reported incidents of overheating smartphones worldwide, Samsung made the unprecedented decision to recall every single one of the Galaxy Note 7 smartphones sold.The company stopped all sales and shipments of the Note 7.We're not sure why the new batteries might have caught fire, as Samsung told us they'd be brand-new.Here's what we know about Samsung's battery rarely.

The basics

The science behind phone battery fires is actually pretty simple, and fairly well understood. Much like the infamous exploding hoverboards, phones use lithium ion battery packs for their power, and it just so happens that the liquid swimming around inside most lithium ion batteries is highly flammable.

If the battery short-circuits -- say, by puncturing the incredibly thin sheet of plastic separating the positive and negative sides of the battery -- the puncture point becomes the path of least resistance for electricity to flow.

It heats up the (flammable!) liquid electrolyte at that spot. And if the liquid heats up quickly enough, the battery can explode.

Why Note 7?

What makes the Note 7 different: Samsung may have accidentally squeezed its batteries harder than it should.
According to a unpublished preliminary report sent to Korea's Agency for Technology and Standards (obtained by Bloomberg), Samsung had a manufacturing error that "placed pressure on plates contained within battery cells," which "brought negative and positive poles into contact."

"The defect was revealed when several contributing factors happened simultaneously, which included sub-optimized assembly process that created variations of tension and exposed electrodes due to insufficient insulation tape," a Samsung representative tells CNET.

What happens next?

These are just a few theories based on one battery expert's remote analysis of Samsung's initial findings. We don't have the whole truth yet, and the truth is what Samsung and government agencies around the world are looking for as we speak. Just one mystery: why the replacement batteries might also be exploding.

Anyhow, organizations like the US Consumer Product Safety Commission have officially stepped in to recall the Galaxy Note 7 and figure out what happened, and they may recall it again.

Week seven - Islamic State

What is 'Islamic State'?

The jihadist group Islamic State (IS) burst on to the international scene in 2014 when it seized large swathes of territory in Syria and Iraq. It has become notorious for its brutality, including mass killings, abductions and beheadings. The group though has attracted support elsewhere in the Muslim world - and a US-led coalition has vowed to destroy it.

What does IS want?

In June 2014, the group formally declared the establishment of a "caliphate" - a state governed in accordance with Islamic law, or Sharia, by God's deputy on Earth, or caliph.
IS seeks to eradicate obstacles to restoring God's rule on Earth and to defend the Muslim community, or umma, against infidels and apostates.The group has welcomed the prospect of direct confrontation with the US-led coalition, viewing it as a harbinger of an end-of-times showdown between Muslims and their enemies described in Islamic apocalyptic prophecies.

What are its origins?

Baghdadi, a former US detainee, became leader in 2010 and began rebuilding ISI's capabilities. By 2013, it was once again carrying out dozens of attacks a month in Iraq.It had also joined the rebellion against President Bashar al-Assad in Syria, setting up the al-Nusra Front.

At the end of December 2013, Isis shifted its focus back to Iraq and exploited a political stand-off between the Shia-led government and the minority Sunni Arab community. Aided by tribesmen and former Saddam Hussein loyalists, Isis took control of the central city of Falluja.

In June 2014, Isis overran the northern city of Mosul, and then advanced southwards towards Baghdad, massacring its adversaries and threatening to eradicate the country's many ethnic and religious minorities. At the end of the month, after consolidating its hold over dozens of cities and towns, Isis declared the creation of a caliphate and changed its name to "Islamic State".

What weapons does IS have?

IS fighters have access to, and are capable of using, a wide variety of small arms and heavy weapons, including truck-mounted machine-guns, rocket launchers, anti-aircraft guns and portable surface-to-air missile systems.

Where does IS get its money from?

It initially relied on wealthy private donors and Islamic charities in the Middle East keen to oust Syria's President Assad. Although such funding is still being used to finance the travel of foreign fighters to Syria and Iraq, the group is now largely self-funding.

Week six - Shanghai Disneyland

Why Shanghai Disneyland's spell is wearing off after six months

High prices and subpar service leave visitors disenchanted

SHANGHAI Half a year after its ballyhooed debut, Shanghai Disneyland is struggling to keep the turnstiles spinning as complaints about high prices and disappointing service spread online.
On a clear morning in early December, lines at the gates were almost nonexistent. Gone were the crowds seen around opening day back in June. In the afternoon, electronic signboards showed only short waits -- five to 50 minutes -- for all but the most popular attractions. Workers killed time chatting at deserted gift shops.
Many of the visitors who did make the trip brought in packed lunches and drinks from convenience stores, including thriving shops inside the nearby subway station. Come lunchtime, patrons spread out on benches to eat.
"I heard everything in the park was expensive, so I bought lunch ahead of time," a college student from Jiangxi Province said, adding that she did not plan to pick up souvenirs or gifts.
High prices were the most common complaint among the visitors. Admission runs 370 yuan ($53.50) on weekdays and 499 yuan on weekends and holidays -- sizable sums given the average monthly wage is just under 6,000 yuan even in Shanghai, where people tend to earn more than in other areas. Tokyo Disneyland, by comparison, charges 7,400 yen ($64.30) for a day's admission.
A 26-year-old Dalian woman visiting with friends said she spent over 2,000 yuan, or half a month's wages, on the two-day trip, including lodging and airfare.
"There are plenty of staff around, but they can't even give clear directions," a college student from Hangzhou said, having asked two separate workers for navigational help, to no avail.
Ongoing expansion projects could burnish the venue's appeal. But large-scale renovations are also in store for Disney parks in Tokyo and Hong Kong, creating more competition. If Shanghai Disneyland cannot solve its customer service problem, cultivating repeat customers will remain challenging, limiting growth in admissions.

Week five - unmanned aerial vehicle

  AeroVironment Launches Quantix Commercial Drone System

Unmanned aircraft systems manufacturer AeroVironment kicked off this year’s Drone World Expo in San Jose, California, by unveiling its new commercial Quantix drone and Decision Support System (DSS). The package includes the Quantix drone—a vertical takeoff and landing multirotor, multi-sensor system—with the company's DSS cloud-based analytics platform.

  Quantix is targeting the agricultural, energy and transportation markets, and AeroVironment is offering the system to customers in versions that include hardware only, hardware plus DSS or flight services that the company can provide for customers who don’t want to operate their own drones.

    “We believe this is the first practical, fully integrated solution for the commercial market,” said Wahid Nawabi, AeroVironment's president and CEO. “Customers don’t want to be experts at UAV operations and data analysis,” he added, noting that the Quantix drone is designed for long life, reliability and ease of operation. AeroVironment has manufactured tens of thousands of drones operating globally in harsh environments, he said, and has a track record of 45 years in this industry.

  The Quantix drone is equipped with four rotors, two on the ends of a single wing. A central fuselage is fitted with two cameras, one an RGB color camera for photographic image capture and a multispectral sensor with normalized difference vegetation index (NVDI) capabilities. All data is stored on SD cards, which can be removed post flight for local analysis or uploaded to AeroVironment’s DSS.

  Operation of Quantix is automatic. Users interface with the drone via a customized tablet computer, by drawing the flight parameters on the screen. “It’s one-touch planning,” said Quantix product line manager Tom Stone. “If you can draw a box on a screen and push a button, you can fly Quantix. You don’t have to learn how to fly it, how to land it, and it’ll take off automatically, plan the mission automatically, fly that mission automatically, come back and land, and you can take the data card and put it in this tablet and you can look at the results immediately.”

  Quantix is designed to operate from small spaces, thanks to its vertical takeoff and landing capability. The drone’s four rotors pull it straight up into the air, then it transitions to horizontal flight for mapping operations. Elevons on the wing trailing edge are used to control pitch when in horizontal flight mode. Yaw is controlled by varying the speed of the rotors. Endurance is about one hour, and 45-minute flights are typical. For landing, Quantix reverts to vertical mode and touches down on rugged fixtures built into the aft fuselage and wingtips. When power drops, Quantix will automatically return to the departure spot. If power is lost completely, it can glide and land with minimal damage.

  The DSS is a cloud-based, secure, open-architecture analytics toolbox accessible via the Web, according to Nazlin Kanji, AeroVironment's program director of unmanned aircraft systems. “It supports the needs of multiple customers in multiple industries. Technology changes very quickly, and [DSS] allows us to incorporate new technology quickly and make it available to our customers.”

  AeroVironment is not yet releasing pricing information on Quantix, and this will depend on how the buyer chooses to use the system, either by purchasing the hardware and operating the drone or by selecting AeroVironmnet to operate Quantix. DSS analytics packages are available in various forms, either by annual subscription or smaller chunks. AeroVironment also expects that some buyers will use Quantix drones to provide mapping/sensin business services. Quantix will begin shipping in spring 2017.

Week four - COP 21

Paris Climate Change Conference

 John Kerry says he will try and sign up to Paris climate treaty before Donald Trump takes office

  The US Secretary of State John Kerry says he will continue his efforts to implement the Paris Agreement on global warming, until the day President Barack Obama leaves office.

  Speaking in New Zealand following a trip to Antarctica, Kerry said his administration would continue to do everything possible to meet its responsibility to future generations. Kerry has long championed climate action but now his legacy is under threat.

  President-elect Donald Trump has called climate change a hoax and said he would "cancel" US involvement in the landmark Paris deal. Under the deal, which came into force this month, countries have agreed to limit global warming to 2C above pre-industrial levels. Achieving the goal will require a major shift away from fossil fuels.

  Kerry said it would be up to the Trump administration to define itself on climate change. He said that sometimes there is a divide between what is said on the campaign trail and what is done in governance.

  But Kerry appeared to take a swipe at Trump when he listed some of the ways in which global warming could already be seen. He said that globally, there were more fires, floods and damaging storms, and sea levels were rising.

  "The evidence is mounting in ways that people in public life should not dare to avoid accepting as a mandate for action," Kerry said.

  He also made a point of crediting a previous Republican president, George H W Bush, with first joining the global effort to address climate change in Rio de Janeiro in 1992.

  "Now the world's scientific community has concluded that climate change is happening beyond any doubt. And the evidence is there for everybody to see," Kerry said. "So we will wait to see how the next administration addresses this."

  He said he thinks his administration is on the right track because the majority of Americans believe climate change is happening and want action.

  Kerry plans to fly this week to a global climate conference in Morocco, where he will give a major speech. Officials there have begun working on a "rulebook" to implement the Paris deal.

Weel three - Paris magazine attack

  Why does France keep getting attacked?

  Undoubtedly, the role France has historically assumed as standard bearer of western secular liberalism has also put the nation in the spotlight. Islamic extremists may see the US as a source of moral decadence and economic exploitation, but France is seen as an atheist power which is both defending western ideals such as human rights, free speech and democracy and, in the eyes of jihadis, trying to impose them on the Islamic world.

  The first big militant attack in France in recent years came earlier , in 2012, and targeted soldiers and the Jewish community. The next major attack was against the offices of Charlie Hebdo, a satirical magazine which had published controversial cartoons of the prophet Muhammad, deemed insulting by many Muslims. Then came November’s Isis-organised strike against a concert hall, bars and a football stadium – all representative of French life. Finally there is an attack on Bastille Day, with all the history and values it represents.

  Successive governments in Paris have also taken a hard – and much publicised – line on issues such as the wearing of full-body coverings and the veil in public, which has been well noted by Islamic militants. So has the increasingly prominent French military role overseas. French forces have made a series of interventions in the Islamic world in recent years – in Libya, in Mali, where its troops rolled back one of the most successful Islamic militant offensives outside Syria or Iraq for many years, and of course in the coalition against Isis.

  Other reasons for the violence are rooted in grave problems within France itself which have made the nation vulnerable.

  Some of these are failings of the fragmented, bureaucratic and still under-resourced security services. A French parliamentary investigation into last year’s terrorist attacks on Paris highlighted a “global failure” of French intelligence and called for the creation of a single, US-style national counterterrorism agency.

  All the extremists involved in the attacks had been previously flagged to authorities, the investigation found. Some had past convictions, or were under judicial surveillance in France or in Belgium when they struck Paris.

  Isis thus seeks to terrorise its enemies and mobilise its supporters but above all polarise those communities, which might then turn against one another. In its literature it has specifically pointed to France as a place where “the grey zone” of tolerance and moderation can be usefully targeted and destroyed.

  Some observers in France have said the nation has been brought closer together by the recent violence. Not all agree. Patrick Calvar, head of the French Direction Générale de la Sécurité Interieure, recently warned that his country was “on the brink of a civil war between rightwing and Islamist extremists”.

  “Extremisms are rising everywhere and … this confrontation, I think it will happen. One or two more attacks, and we will see it,” Calvar said last month.
