Trump taps national security veteran for White House role

WASHINGTON (AFP) - US president-elect Donald Trump on Friday hired as a senior adviser a Republican national security veteran who first worked in the White House situation room under Richard Nixon. As deputy national security adviser, 65-year-old Fox News commentator Kathleen Troia "KT" McFarland, will return once again to the executive mansion as number two to former general Mike Flynn.

"She has tremendous experience and innate talent that will complement the fantastic team we are assembling," Trump said, in a statement issued from his luxury Florida golf resort. White House national security roles do not need to be confirmed by the Senate, so McFarland will take up her duties when President Barack Obama passes Trump the baton on January 20 next year.

She would in any case have been an uncontroversial choice, with decades of experience under three former Republican presidents and as a former aide to foreign policy heavyweight Henry Kissinger.

She has never herself held elected office, but in 2006 was defeated in a bid to seek the Republican nomination to challenge then New York senator Hillary Clinton s successful re-election bid.


Her most prominent roles before joining Fox News were as deputy assistant secretary of defense for public affairs under president Ronald Reagan and between 1982 and 1985 as defense secretary Caspar Weinberger s speechwriter and spokeswoman.

McFarland s appointment came as Trump was ensconced with senior advisors in his Mar-a-Lago resort drawing up transition plans. A spokesman said no more major decisions are expected before Monday.

Erdogan, Putin in Syria talks after Turkish soldiers killed

ISTANBUL (AFP) - Turkish President Recep Tayyip Erdogan discussed the Syrian conflict with his Russian counterpart Vladimir Putin by phone Friday after the Turkish army accused Moscow ally Damascus of killing its soldiers in northern Syria. Erdogan informed Putin of the strike that killed four Turkish soldiers, presidential sources said, which the Turkish army assessed to have been by the forces of President Bashar al-Assad early on Thursday.

It was the first time Turkey had blamed the Assad regime -- which is given military support by Russia -- for a deadly strike on its troops during Ankara s three month campaign inside Syria.

Erdogan and Putin also agreed to accelerate their efforts to find a solution to the humanitarian crisis in Aleppo, where the regime continues its Moscow-backed offensive to recapture the whole city, which is divided between the government and rebels.

During the phone call, Erdogan told Putin of how the Turkish-backed offensive in Syria was evidence of Ankara s determination to fight against terror, the sources added.


The president stressed Turkey s commitment to Syria s territorial integrity -- Russia had previously said it was "deeply concerned" by Turkey s incursion while Damascus has called it a "blatant violation of sovereignty".

The presidents also backed the process to normalise relations between Russia and Turkey after the crisis sparked by the shooting down by Turkish forces of a Russian jet over Syria last year.

The army said on Friday that a fifth Turkish soldier was killed in northern Syria in clashes with Islamic State (IS) jihadists. 

Seventeen Turkish soldiers have been killed since the military began an unprecedented operation in Syria on August 24 to back pro-Ankara rebels.

Turkish planes also carried out air strikes against seven IS targets in northern Syria, the army said in a statement on Friday carried by the state-run Anadolu news agency.

Turkey launched the operation in August -- dubbed "Euphrates Shield" -- in support of Syrian rebel fighters seeking to retake IS-held territory in northern Syria and also to halt the advance of Kurdish militia.

Since it began, the pro-Ankara rebels have captured the IS stronghold of Jarabulus, cleared IS from Al Rai and retaken the symbolically important town of Dabiq without much resistance.

They are now pressing to take Al Bab from the jihadists and will then move to Manbij to ensure there are no Kurdish militia members remaining, as agreed with Washington.

The battle to recapture Al Bab appears to be proving more difficult and violent as Dogan news agency reported on Friday evening that five more soldiers were injured after an IS attack.

They have been taken to the southeastern city of Kilis for medical treatment, Dogan said, adding that the total number of soldiers wounded in the day s action was seven.

44 dead as trains collide in Iran

TEHRAN (AFP) - Two trains collided and caught fire Friday in a remote region of northern Iran, killing 44 people and injuring dozens more, in one of the country s worst rail disasters.Provincial governor Mohammad Reza Khabbaz told state television that the crash took place in Semnan province on the main line between Tehran and Iran s second city Mashhad.

An express train operating from Tabriz in the northwest to Mashhad had stopped, Khabbaz said, initially suggesting the cause could have been mechanical failure or extreme cold, although it was later put down to human error.

Two coaches on the express burst into flames when a passenger train behind smashed into the back of it at 7:50 am (0420 GMT). The front four coaches of the second train -- running from Semnan to Mashhad -- derailed and overturned.


"One minute I was sleeping and the next I was being carried out of a coach on fire," one hospitalised passenger told state television.

Television broadcast images of a huge column of black smoke and flames shooting into the sky from coaches with their windows shattered, as firefighters battled the blaze and rescue workers searched for victims.

With the toll climbing throughout the day, Hossein Kulivand, head of Iran s emergency services, said late Friday that 44 people were killed and 82 hospitalised, of whom 17 were treated for light injuries and released.

Human error was determined to have caused the accident.

"For some unknown reasons due to human fault, the train (from Semnan) was ordered to move and so it hit the other train from behind," said Mohsen Poor-Seyed Aghaie, the head of Iranian railways.

The province s Red Crescent director, Hassan Shokrollahi, said the remo
te location of the crash site, between Semnan and Damghan, the next major town, had complicated rescue efforts.

"Due to the difficulty of access, only our helicopter has managed to reach the scene," he said.

The injured were airlifted to hospitals in Semnan and Damghan.

The Tehran-to-Mashhad line was briefly closed to allow an investigation into the cause of the crash, said Sadegh Sokri, spokesman for Iran s railways.

A collision on the same line between a freight train and a passenger train left two dead and 30 injured in June 2014.

President Hassan Rouhani called for "all technical, administrative and preventive measures to be taken to prevent the recurrence of such an accident".

Iranian trains have been involved in four collisions this year with road vehicles, including a crash with a truck in July that left around 30 injured near the Caspian Sea in the northern province of Mazandaran.

Collisions between trains are rarer.

In the country s deadliest rail disaster, 328 people were killed when a train transporting sulphur, petrol and fertilisers exploded in northern Iran on February 18, 2004.

Iran s roads are notoriously deadly, mainly because drivers show scant regard for rules, with 16,000 lives lost in the Iranian year between March 2015 and March 2016.

In a sign of progress, however, an average of 28,000 deaths a year were registered on Iranian roads a decade ago. 

Syria army advances in rebel-held east Aleppo

ALEPPO (AFP) - Syrian army units advanced in Aleppo on Friday and pounded rebel-held eastern neighbourhoods with air strikes and shelling, causing new deaths among besieged civilians and adding to their despair.

The US military, meanwhile, announced its first combat loss in Syria, saying a service member had been killed by a bomb during an offensive against the Islamic State group.

Ten days into the offensive to recapture all of Syria s battered seco
nd city, regime bombardment has killed 196 civilians, including at least 27 children, in east Aleppo, a monitoring group said.

On Friday, regime forces pounded several eastern districts with air strikes and shelling that killed eight civilians, the Britain-based Syrian Observatory for Human Rights said.

Clashes also rocked Masaken Hanano, east Aleppo s largest district, more than 60 percent of which is now under the control of regime forces, the monitor added.

State television said the army was advancing into Masaken Hanano "from three axes", calling it the "largest front" in the battle for Aleppo, the capture of which could deal a decisive blow to rebels.

More than 250,000 civilians have been besieged in eastern Aleppo since July, with food and fuel supplies dwindling and international aid exhausted.

The Observatory said four children fled Friday to Sheikh Maqsud, a Kurdish-controlled enclave between the government-held west of Aleppo and the east.

But rebels prevented "dozens of families" from Bustan al-Basha from leaving, it said.

And regime raids on two villages west of Aleppo killed at least 15 civilians on Friday, four of them children, said the Observatory.

Damascus says east Aleppo residents and surrendering fighters are free to leave but accuses the rebels of using civilians as "human shields".

Residents endured a brutal night Thursday of bombardment during which 32 civilians, including five children, were killed.

"I m terrified by the army s advance and the increasing bombardment," said Abu Raed, a father-of-four from the Fardos neighbourhood.

"There s no safe place for me and my family."

Rescue workers in several parts of the east battled to extricate civilians trapped under the rubble of bombed buildings.

In Bab al-Nayrab, an AFP cameraman saw them struggle for more than an hour to pull out a boy who was stuck from the waist down in the rubble, with the back of his head badly gashed.

"Living under these circumstances is unbearable," said 43-year-old Mohammed Haj Hussein, in Tariq al-Bab district.

"There s no work, there s no food, and the bombing is incessant... I want to get out of here by any means possible."

Resident Abu Hussein added: "I don t know what the UN is waiting for. Why don t they at least evacuate the children and women?"

Retaliatory rocket fire by the rebels has killed at least 18 civilians in the government-held west, 10 of them children, since the regime assault began on November 15, said the Observatory.

The UN says it has a plan to deliver aid to Aleppo and evacuate the sick and wounded, which rebel factions have approved.

But Damascus has yet to agree, and additional guarantees are needed from regime ally Moscow, UN officials say.

On Thursday, the head of the UN-backed humanitarian taskforce for Syria, Jan Egeland, warned there was no plan B to help civilians in east Aleppo.

"In many ways plan B is that people starve, and can we allow that to happen? No we cannot," he said.

Further east, in Raqa province, where a US-backed alliance of Kurdish and Arab fighters is battling IS, Washington suffered its first combat loss in Syria, the coalition announced.

It said the service member died on Thursday from wounds caused by an improvised bomb near the town of Ain Issa.

US special forces are on the ground in the area supporting an offensive to retake the city of Raqa, the jihadists  de facto Syrian capital.

Also on Friday an air strike carried out by an unidentified aircraft hit a small maternity hospital in the north of Idlib province, killing a civilian and putting the clinic out of service, said the Observatory.

Rebel-held areas in the Eastern Ghouta near Damascus were also pounded by regime forces on Friday, the monitor said, killing at least two civilians and wounding 15 in the town of Douma.

The charity Doctors Without Borders (MSF) reported "multiple air strikes" on Eastern Ghouta, adding that the number of the wounded "is still being counted."

At least 49 civilians have been killed in regime bombardment on the rebel stronghold since November 17, almost half of them children, said the Observatory.

UK citizens could pay to retain EU perks

UK citizens could pay to retain EU perks, says top negotiator

LONDON (AFP) - Britons wanting to retain benefits of European Union membership after the country leaves could pay Brussels for individual citizenship, European Parliament s lead Brexit negotiator Guy Verhofstadt told The Times on Saturday.

"Many say  we don t want to cut our links ," the former Belgian prime minister told The Times.

"I like the idea that people who are European citizens and saying they want to keep it have the possibility of doing so. As a principle I like it."

Prime Minister Theresa May has vowed to trigger Article 50 of the Lisbon Treaty by March, setting the ball rolling on two-years of negotiations to set the terms of the divorce.

Trade and immigration are set to be the key issues, with European leaders saying they will not compromise on open borders within the bloc.

Brexit-supporting MP Andrew Bridgen accused Verhofstadt of trying to sow division in Britain.

"It s an attempt to create two classes of UK citizen and to subvert the referendum vote," he told the Times.

"The truth is that Brussels will try every trick in the book to stop us leaving."

Cuban revolutionary icon Fidel Castro dies

HAVANA (AFP) - Guerrilla revolutionary and communist idol, Fidel Castro was a holdout against history who turned tiny Cuba into a thorn in the paw of the mighty capitalist United States.

The former Cuban president, who died aged 90 on Friday, said he would never retire from politics.

But emergency intestinal surgery in July 2006 drove him to hand power to Raul Castro, who ended his brother’s antagonistic approach to Washington, shocking the world in December 2014 in announcing a rapprochement with US President Barack Obama.

Famed for his rumpled olive fatigues, straggly beard and the cigars he reluctantly gave up for health reasons, Fidel Castro kept a tight clamp on dissent at home while defining himself abroad with his defiance of Washington. In the end, he essentially won the political staring game, even if the Cuban people do continue to live in poverty and the once-touted revolution he led has lost its shine.

As he renewed diplomatic ties, Obama acknowledged that decades of US sanctions had failed to bring down the regime -- a drive designed to introduce democracy and foster western-style economic reforms -- and it was time to try another way to help the Cuban people.

A great survivor and a firebrand, if windy orator, Castro dodged all his enemies could throw at him in nearly half a century in power, including assassination plots, a US-backed invasion bid, and tough US economic sanctions.

Born August 13, 1926 to a prosperous Spanish immigrant landowner and a Cuban mother who was the family housekeeper, young Castro was a quick study and a baseball fanatic who dreamed of a golden future playing in the US big leagues.

But his young man’s dreams evolved not in sports but politics. He went on to form the guerrilla opposition to the US-backed government of Fulgencio Batista, who seized power in a 1952 coup.

That involvement netted the young Fidel Castro two years in jail, and he subsequently went into exile to sow the seeds of a revolt, launched in earnest on December 2, 1956 when he and his band of followers landed in southeastern Cuba on the ship Granma.

Twenty-five months later, against great odds, they ousted Batista and Castro was named prime minister.

Kuwaitis vote amid disputes over subsidies

KUWAIT CITY (AFP) - Kuwaitis vote Saturday to elect the seventh parliament in a decade in the oil-rich Gulf emirate, at a time of sharp disputes over subsidy cuts due to falling oil revenues. The snap polls see the return of opposition groups after a four-year boycott in protest at the government’s amendment of the electoral law.

Opposition candidates called at their election rallies for wide democratic reforms, promising to fight for economic and social justice and to end rife corruption. The government’s austerity measures, mainly hiking petrol prices, were the top issue at election rallies.

"The government will most likely accede to some of the demands of the opposition," but stand firm on others, Stratfor, a leading intelligence platform, said in a report. 


"The country has the financial luxury of taking a long-term view on reform. Even if it continues to draw down its sovereign wealth fund by $30 billion a year for 10 years, it would still have roughly half the fund left," Stratfor said.

Analysts see little hope the election will bring political stability to the Gulf state, which has been rocked by lingering disputes since mid-2006, apart from a period of relative calm after 2013.

The emir dissolved the last parliament after MPs called for ministers to be grilled over subsidy cuts, in a state with a traditionally generous cradle-to-grave welfare system. Around 30 opposition figures, out of 300 candidates, including 14 women, are running for the 50-seat parliament. Half of the opposition candidates are Islamists.

Four suicide bombers killed in attack

Four suicide bombers killed in attack on Ghalnai Camp in Mohmand Agency

ISLAMABAD (AWE) - A group of militants attacked a mosque at an army facility in Mohmand Agency on Saturday morning, triggering a shootout in which four terrorists were killed.

According to Inter Services Public Relations (ISPR), four suicide bombers tried to enter Ghalnai Camp at around 6:00am and started firing after they reached the mosque, where residents and a large number of recruits were present.

The attackers were "contained in the outer courtyard" of the mosque, and subsequently all four were killed. During the exchange of fire, two soldiers embraced martyrdom and 14 others were injured.

Sartaj Aziz briefs heads of P5 Missions on India's

Sartaj Aziz briefs heads of P5 Missions on India's unprovoked firing on LoC, Working Boundary

ISLAMABAD (Web Desk)  - The Adviser to the Prime Minister on Foreign Affairs, Mr. Sartaj Aziz briefed the heads of Missions of the permanent members (China., France, Russian Federation, UK and USA) of the UN Security Council on Friday afternoon regarding the continued unprovoked ceasefire violations by the Indian occupation forces at the Line of Control (LoC) and the Working Boundary (WB).

The Adviser strongly condemned the reprehensible attack on the civilian bus in the Neelum Valley on 23 November 2016, in complete violation of the 2003 Ceasefire Understanding and international law, especially the international humanitarian law. The Indian occupation forces also fired upon the ambulances that had come to rescue the injured people from the site of the attack. The deliberate targeting of civilian populated areas is condemnable and deplorable and must be investigated.

He referred to persistent ceasefire violations by India, especially during the last two months, resulting in the loss of more than 45 innocent civilian lives and injuries to more than 139 others at the LoC and WB in an effort to divert international attention from the continuing human rights violations in the Indian occupied Jammu and Kashmir (IoK). He stated that the Indian belligerence is a threat to the regional peace and security and can lead to a strategic miscalculation, which would be disastrous for the region.

Sartaj Aziz has also addressed letters to the Foreign Ministers of the permanent members of the UN Security Council, on the escalation at the LoC and Indian ceasefire violations. Copies of these letters were also handed over to the heads of Missions.

The Adviser once again called upon the permanent members of the UN Security Council to play their crucial role in maintaining global peace and security and urge India to immediately put an end to the escalation and bloodshed at the LoC. 

Rangers arrest MQM-London activist

Karachi: Rangers arrest MQM-London activist, recover arms

KARACHI (Dunya News) - Rangers conducted an operation in Garden Shoe Market area of Karachi on Friday and arrested a terrorist Ateeq alias Chinga belonging to Muttahida Qaumi Movement-London (MQM-London) on charges of having links with Indian spy agency RAW, Dunya News reported.

According to Rangers spokesman, the arrested terrorist was involved in extortion and target killing cases in the city. Rangers also recovered huge cache of arms from an under-construction shop in the Garden Shoe Market on the information provided by the arrested terrorist. 

The spokesman further informed that arms stored in the building, included two LMGs, four SMGs, one 22-bore riffle, three 12-bore pistols and 5809 bullets, were to be used in target killing incidents in Karachi on the instruction from top leadership of MQM-London.

Parties Hurriyat Conference (APHC) Kashmir

History won't deny Pakistani efforts over Kashmir dispute: Gilani

SRINAGAR (Dunya News) – Syed Ali Gilani, one of the leaders of All Parties Hurriyat Conference (APHC) has said on Friday that positive efforts by Pakistan over dispute of Kashmir with India would not be denied in history.

In an exclusive talk with Dunya News, Gilani said that Kashmiris would side with Pakistan if Indian government lodged a war against the neighbour. He reported that Indian state-terrorism claimed 98 innocent lives in the valley in past five months.

Over 825 youth have lost eyes to the use of pellet guns, he added. 

Gilani branded Pakistan Army as the ‘Islamic army’.

India has been occupying Kashmir valley for at least seven decades and have fought three wars with Pakistan over the dispute.

Indian government, after separation of the subcontinent, had vowed to have referendum done and act accordingly but nothing has been done until 2016.

Mother, three children killed in gas leakage blast in Nankana Sahib

NANKANA SAHIB (Dunya News) – At least four people were killed as roof of a house caved in due to cylinder blast in Nankana Sahib today (Saturday). According to details, Malikabad’s locals turned on stove to fight cold and slept after which it exploded late night, causing roof collapse. Mother Allah Rakhi and her three children eight-year-old Azam, seven-year-old Nazim and five-year-old Maria trapped under the rubble.

Getting information about the incident, rescue team arrived at the scene and shifted the victims to hospital where they succumbed to injuries.

Lung cancer cells spread like unanchored tents, study says

Spreading lung cancer cells are like tents which have collapsed and are adrift in the wind, scientists from the University of York have discovered.
Communication between two proteins is what triggers the cell tent to lose its shape and become unanchored, their research found.
This allows the cells to travel to other areas of the body.
The researchers said their findings could help prevent the spread of lung cancer.
Writing in the Journal of Clinical Investigation, researchers from York and the University of Texas describe how the communications centre of a cell - known as the Golgi apparatus - receives a signal from proteins which prompts the movement of membrane sacks inside it.
This movement alters the shape and surface of the cancer cell, allowing it to break free from its moorings and move around freely.

Collapsing sides

Dr Daniel Ungar, from the University of York's biology department, said it was apt to think of the cancer cell resembling a tent structure.
"It has fixed sides to hold its shape and is firmly anchored to the ground in order to secure its contents.
"In order to move the tent, we have to rearrange its contents and collapse its sides in order to lift it out of its anchored position and carry it away," he said.
He added that a similar process happens with cancer when it spreads - its outer edges are altered leaving it unanchored.
The study found that a protein called Zeb1 was critical to this process and the research team now want to look at how to target the protein without damaging healthy cells, in which the protein also exists.
The researchers only looked at lung cancer cells and do not know if the same process occurs in other cancers.

Zika outbreak: What you need to know

The World Health Organization has declared the Zika virus a global public health emergency.
The infection has been linked to thousands of babies being born with underdeveloped brains.
Some areas have declared a state of emergency, doctors have described it as "a pandemic in progress" and some are even advising women in affected countries to delay getting pregnant.
But there is much we do not know.

Low social status 'can damage immune system'

Simply being at the bottom of the social heap directly alters the body in ways that can damage health, a study at Duke University in the US suggests.
Monkey experiments showed low status alters the immune system in a way that raises the risk of heart disease, diabetes and mental health problems.
One expert said the findings were "terrifically applicable" to people.
The findings, in Science, had nothing to do with the unhealthy behaviours that are more common in poorer groups.
The gulf in life expectancy between the richest and poorest is huge - in the US it is more than a decade for women and 15 years for men.
Part of the explanation is that people from poorer backgrounds are more likely to have a worse lifestyle - including smoking, little exercise and diets containing junk food.
But the latest study goes further to show low status - with all of those other factors stripped out - still has an impact on the body.
Looking at 45 non-human primates allowed scientists to adjust only social status to assess its impact - something impossible to do in people.
The captive Rhesus monkeys - who were all female, unrelated and had never met before - were divided one-by-one into nine new groups of five.
The newest member nearly always ended up at the bottom of the social order and became "chronically stressed", received less grooming and more harassment from the other monkeys.
A detailed analysis of the monkeys' blood showed 1,600 differences in the activity levels of genes involved in running the immune system between those at the top and bottom.
It had the impact of making the immune system run too aggressively in those at the bottom. High levels of inflammation cause collateral damage to the body to increase the risk of other diseases.
One of the researchers, Dr Noah Snyder-Mackler, told the BBC News website: "It suggests there's something else, not just the behaviours of these individuals, that's leading to poor health.
"We know smoking, eating unhealthily and not exercising are bad for you - that puts the onus on the individual that it's their fault.
"Our message brings a positive counter to that - there are these other aspects of low status that are outside of the control of individuals that have negative effects on health."
Further experiments showed the immune system was not fixed and could be improved, or made worse, by mixing up the social rankings.
Sir Michael Marmot, one of the world's leading experts on health inequalities and based at University College London, said the findings were "extraordinarily interesting" and underpinned much of his own research.
He told the BBC News website: "This is hard science saying there's a plausible biological mechanism that results in clear differences depending where you are in the hierarchy.
"The gateway through which the social environment impacts health is the mind. Whether it is unhealthy behaviours or direct stress, the mind is crucial and this study is lending real credence to that."

'Governments don't get it'

While Rhesus macaques do form strict societies, they are far more simplistic that human ones.
But Prof Graham Rook, from University College London, told the BBC Newswebsite: "All the evidence is showing the findings are terrifically applicable to humans."
He pointed to evidence suggesting people at the bottom end up with worse health when the top gets richer, even if they themselves do not get any poorer.
He said: "It is something governments just don't understand; they think people at the bottom have got cars, have got TVs, so compared with people in India they're enormously wealthy.
"But that really isn't the point, they feel they are at the bottom of the heap."
Hierarchies are a fixture of society. However, the researchers believe more can be done to ease the health problems coming from being bottom of the pile.
Dr Snyder-Mackler said: "Status is always relative, but if we could flatten the slope so the differences between the highest and lowest weren't as much, or find ways to focus attention on lower social environments so they are not as 'crappy' we could mediate some of those consequences.
"It's a hard problem that might never be fixed, but it might be possible to make it less worse."

Bumper load of new viruses identified

An international research team led from Australia and China has discovered nearly 1,500 new viruses.
The scientists looked for evidence of virus infection in a group of animals called invertebrates, which includes insects and spiders.
Not only does the study expand the catalogue of known viruses, it also indicates they have existed for billions of years.
The findings were published in the journal Nature.
Few would argue that all living species on Earth are susceptible to viruses – these microscopic parasites are ubiquitous.
But virologists have long suspected that our current view of the diversity of viruses is blinkered – all too often constrained to those causing disease in humans, animals and plants, or to those that we can grow in the laboratory.
A trip to a tropical rainforest or the African savannah gives a snapshot into the incredible diversity of visible life on Earth, but understanding the potentially mind-boggling myriad of minuscule viruses has not been so easy.
Capturing new viruses is not like netting a new species of butterfly – viruses are invisible.
Undeterred by this practical problem an international team was keen to survey invertebrates for new viral species.
Invertebrates are spineless creatures and the group includes many familiar animals, such as insects, spiders, worms and snails. They represent the vast majority of animal species in the world today.
Scientists wanting to work out the totality of viral "life" – although many virologists would argue that viruses are not truly alive – are starting to adopt techniques that reveal their genetic calling cards, revealed in the things they infect.
Just like powerful new telescopes are peering deeper into space, revealing a wealth of hitherto unknown stars, next-generation sequencing techniques are providing new insight into the magnitude of the invisible world of viruses; a world we call the virosphere.
We are familiar with DNA, the "stuff of life" that makes up the blueprint of our genomes. But many viruses use a different chemical to construct their genomes – a substance known as RNA.
Just like DNA, this consists of strings of individual building blocks, or bases; each designated by a different letter: A, C, G and U.
Next generation sequencing allows researchers to quickly determine the sequence of these letters. And if you work out the order of the letters on any chain of RNA, you can determine if it belongs to a virus and whether or not the virus is new.
Its potential for virus discovery is huge.
The research team collected around 220 species of land- and water-dwelling invertebrates living in China, extracted their RNA and, using next-generation sequencing, deciphered the sequence of a staggering 6 trillion letters present in the invertebrate RNA "libraries".
When the researchers analysed this mass of data they realised that they had discovered almost 1,500 new virus species – a whopping number by any measure. Many of these were so distinct that they did not easily fit into our existing virus family tree.
Prof Elodie Ghedin from New York University, who was not directly involved with the study, told the BBC: "This is an extraordinary study providing the largest virus discovery to date.
"It will no doubt remodel our view of the virus world and redraw virus phylogeny.
"This is what happens when you combine a bold and brute force approach with the right technology and the right set of eyes."
Even though some invertebrates carry viruses that can infect humans - like zika and dengue - the study authors do not think that these newly discovered viruses pose a significant risk.
However, this cannot be ruled out entirely, and Prof Ghedin thinks that this is an important issue to address.
"If we have learned anything from these types of true discovery projects is that when we start looking into places we haven’t looked at before, we find an incredible richness that goes beyond what was suspected.
"It also makes a strong case for expanding virus surveillance to invertebrates in our quest to better understand (and predict) emerging viruses," she said.

'Looking back'

The research also showed that throughout time viruses have been trading genetic material to create new species – an incredible feat according to Prof Eric Delwart from the University of California, San Francisco, who told the BBC: "It shows a lego-like ability of different viral functional units to be recombined to create new viruses even when they originate from highly divergent viruses. The plasticity of viral genomes continues to amaze."
Not only have these studies expanded our view of the diversity of viruses, they have also provided a more complete picture of virus history, as Prof Edward Holmes from the University of Sydney, who was involved in the study explained: "We have discovered that most groups of viruses that infect vertebrates – including humans, such as those that cause well-known diseases like influenza – are in fact derived from those present in invertebrates."
He also believes that his group's data shows that viruses have been infecting invertebrates for possibly billions of years, raising the prospect that invertebrates are the true hosts for many types of virus.
The researchers hope that next-generation sequencing can pave the way for virus discovery in a variety of other species. And it does not stop there.
Prof Delwart thinks that further analyses of existing next-generation datasets may yield additional virus species unlike any that we have seen before.
If future studies reveal anywhere near this number of new viruses, then we’ve only just scratched the surface. It seems that the virosphere is set to explode.
Jonathan Ball is a professor of virology at Nottingham University. This coming Saturday, he will be taking part in CrowdScience, the new BBC World Service science weekly, which starts with a question from listener Ian in Jordan which is "where did viruses come from?"

Seasonal wetlands face uncertain future

Seasonal wetlands - ecologically important habitats that become visible during rainy seasons - are facing an uncertain future, warn scientists.
These ephemeral ecosystems support unique flora and fauna species that do not occur in permanent wetlands. Yet these poorly understood habitats are being lost to future generations as a result of poor land-use practices, the authors observed.
Although these intermittent, shallow-water seasonal natural features are most closely associated with arid or semi-arid landscapes, they are more widespread than generally realised. 
Changing landscape
"They tend to occur during the rainy season which is when you will see shallow water but for most months of the year, it will appear to be dry," explained co-author Tatenda Dalu, from Rhodes University, South Africa.
The seasonal wetlands are dominated by aquatic biodiversity, he told BBC News.
"You have your plankton, you have your insects, which then brings in the birds to feed on these insects," Dr Dalu said.
"Some of these systems have unique communities of fish, such as the 'land fish'."
However, these unique ecosystems were vulnerable for a number of reasons, explained Dr Dalu.
"The biggest threat we are seeing at the moment is either the digging up of the ecosystems or making them permanent.
"By making them permanent, people accidently introduce invasive species which then wipe out the unique invertebrate communities."
For example, people look to have a lake full of fish on their land. Very often, the introduced species of fish results in the unique habitat that had previously thrived in the intermittent water being squeezed to the point of becoming locally extinct.
The team also recognised that changes to the climate system were set to alter rainfall and temperature patterns.
The researchers observed in their paper: "In tropical regions of southern Africa, for example, drought is projected to be particularly problematic.
"In such areas, ephemeral wetlands are highly likely to be affected given that ephemeral aquatic environments are internally drained systems, wholly reliant on localised rainfall."

Enriching features

Dr Dalu said the time to act to attempt to make the wetlands more resilient was now.
"One of the most important things for us is to try to map as many of the systems as we can.
"Having a record of where these unique systems exist will be important for the development of any further legislation."
He said that the flora of ephemeral wetlands enriched people's lives, even if they were not aware of the ecological importance of such sites.
"People will tell you about some of the unique flowers they see there," he said.
"That's how people identify them but they do not know anything else about these seasonal wetlands."
