Invisible fungi revealed by their genetic material

How can new life forms that we cannot see be discovered? Using a novel method based on looking for DNA in soil samples, researchers at Uppsala University have revealed the existence of two hitherto unknown, but very common fungus species. They are thought to perform a key function in the ecosystem, but their exact role remains to be clarified. The study is published in the journal IMA Fungus.

To most people, the word ‘fungus’ conjures up something like a chanterelle or fly agaric, rising vertically from the ground. Since a huge number of fungi do not form distinct fruit bodies, however, they do not catch the eye. This applies, for example, to the newly discovered fungi. Invisible to the naked eye, they are nonetheless common in forest soils in Northern and Central Europe, as DNA analyses of soil samples show.

The researchers found the fungi in soil samples from the Ivantjärnheden field station near Jädraås, in the province of Gästrikland, in east central Sweden. The method developed by the scientists is based on extracting both long DNA sequences, to investigate species interrelationships, and short DNA sequences to get an idea of how common species are.

“Our data show that these two are closely related but distinct species that compete for resources in the soil profile. One wins out, and is dominant, in organic soil; we’ve named it Archaeorhizomyces victor. In second place we have Archaeorhizomyces secundus, which makes do with resources in mineral soil to a greater extent,” says Anna Rosling of the Department of Ecology and Genetics at Uppsala University, who headed the work.

Where the two species coexist—in soil and roots in mixed and coniferous forest—Archaeorhizomyces victor thus predominates in the humus-rich soil. Just a little further down in the ground, where the soil contains less nutrients, victor does poorly and secundus can become widespread.

These species belong to the class Archaeorhizomycetes and, as such, to a group of ancient fungal root endophytes: fungi that colonize plants’ root tissue internally and live in symbiosis with the host, enhancing plant performance and causing no obvious harm. From soil samples around the world, the researchers know that this class comprises at least 1,000 species. These fungi are common; in soil samples from Ivantjärnheden, for example, they make up roughly 30 percent of all sequenced genetic material. This large fungus group was first described scientifically in 2011 and then, too, it was Anna Rosling and her research group who made the discovery, and also succeeded in cultivating two species in their laboratory. The fungi then grew enough to permit more detailed study. Rosling describes them as slow-growing and somewhat beige in color, and says they form differently shaped spores.

With these two newly discovered fungi, the known species of Archaeorhizomycetes have doubled in number. Even more important, the researchers think, is the fact that they have established a method of identifying new species that does not depend on cultivation, or on finding a fruiting body. And much remains to be discovered in the fungus kingdom. The presence of certain marker genes in soil samples indicates that nearly 90 percent of all fungi have yet to be scientifically described.

“With our study, we want to give an idea of the tremendous diversity of fungi in the soil and the importance of naming them, even if we haven’t seen them with the naked eye yet,” Rosling says.

Deputy UN chief pushes Security Council on global ceasefire, to fight ‘common enemy’

Deputy UN chief pushes Security Council on global ceasefire, to fight ‘common enemy’

“I count on your commitment to this appeal”, Amina Mohammed told the meeting via videoconference, on factors driving civil strife worldwide. “And I count on your renewed political and financial investments in prevention and solutions, to stave off security and conflict risks, at a time when the world needs peace and calm more than ever before”.  

She informed that the pandemic continues to exacerbate the risks and drivers of conflict, “from cross-border insecurity and climate-related threats, to social unrest and democratic deficits”.

“Grievances and inequalities are deepening, eroding trust in authorities and institutions of all kinds, and increasing vulnerabilities”, she said.

Millions of women at risk

The deputy UN chief cited the diverse impacts of the pandemic on economic and social inequalities, as well as on the promotion and protection of human rights, especially for women.

“Parties to conflict are taking advantage of the pandemic to create or aggravate insecurity and impede medical care and other life-saving assistance and services”, she attested.  

At the same time women are disproportionately employed in the sectors most affected by lockdowns – where there is “an alarming spike” in gender-based and domestic violence – and are more likely than men to lack savings, social security and health coverage. 

“How can we talk about peace and security when millions of women are at greatest risk in their own homes? And we know there is a straight line between violence against women and girls, civic oppression and conflict”, stated Ms. Mohammed.

Climate driver

Turning to linkages between climate change and security challenges, she dubbed the climate emergency “a major driver of inequality, insecurity and conflict”. 

She recounted her own fact-finding missions in the Sahel, Lake Chad region and Middle East, noting connections between the large-scale displacement of people and “extreme weather events like droughts and floods that destroy homes, livelihoods and communities”. 

“In some cases, the climate crisis threatens the very existence of nations”, Ms. Mohammed spelled out.

‘Stalled’ development 

The UN official also pointed to “stalled” progress on development that is continually being addressed in a “fragmented” manner.

While noting, “the drivers of conflict are not static: they change and evolve”, so too are the opportunities, including new means for learning and growing, she continued.

“The pandemic has already shown that rapid change is possible, as millions of people adopt new ways of working, learning and socializing”, the deputy chief said, urging everyone to “build forward better”.   

She also maintained that recovering from COVID has “reinforced the need for the 2030 Agenda for Sustainable Development – our ultimate prevention tool”, including on gender equality, and upholding the rule of law and good governance.

She called for a “whole-of-UN approach” to the contemporary challenges and drivers of conflict, which must include all Member States.

‘Unequal world order’

Munir Akram, President of the Economic and Social Council (ECOSOC), attributed the UN’s failure in living up to “the ideals of collective and cooperative security” to an “unequal world order”.

The root causes of conflicts “range from the internal struggles for scarce resources; external contests for precious natural resources, and interventions designed to suppress the struggle of peoples to reclaim their own political and economic destinies”, he said.

COVID factor

And due to the COVID-19 pandemic, the world economy is projected to contract by 5-10 per cent, depending on when the virus can be brought under control, according to the ECOSOC chief. 

Noting that over a 100 million people will likely be pushed back into poverty, he flagged that “as usual”, the poorest countries and people “will suffer the most”. 

Unless they receive financial assistance, Mr. Akram said “many developing economies – with lost revenues and laden with unplayable debt – are likely to face economic collapse”, which “would spread chaos and further inflame regional conflicts and global tensions”. 

A toxic brew

Ibrahim Mayaki, head of the New Partnership for Africa’s Development (NEPAD), painted a picture of African populations migrating to cities, including in largely rural countries, warning that conflict only adds to the difficulties States face in providing services for rural dwellers.

He noted that some African border areas, are virtual magnets for violence perpetrated by armed groups and warned that global warming in the Sahel is bringing about “extreme climate events”.

Chairing the meeting – his Caribbean island nation holding the Council presidency for November – Prime Minister of Saint Vincent and the Grenadines, Ralph Gonsalves, reminded that most of the region’s problems do not have military solutions and rejected any solutions that bypass the needs and aspirations of local populations.

He underscored the Government’s urgent responsibility to “end suffering” especially in conflict settings, adding that current chasms cannot be overcome with “baby steps.”

WATCH: Grand Forks man challenges police officer about new city mask mandate and wins, citing religion and health concerns

GRAND FORKS, N.D. — Grand Forks’ mask mandate was put to the test at City Hall Monday night, Nov. 2.

Anti-mask supporter David Waterman proved the mandates put in by Mayor Brandon Bochenski and the city council have very little weight.

The mandates regarding city buildings and mask-use around the city do not have any penalties attached.

The citywide mandate was originally proposed with a penalty, but was ultimately shot down.

After a one-hour protest outside of city hall that was attended by two dozen people, including children, was organized by Waterman, he attempted to enter city hall for the city council meeting.

However, a Grand Forks police officer told him he had to wear a mask.

Waterman refused, citing religious and unspecified health concerns.

The Grand Forks police officer called his supervisor and ultimately allowed Waterman, along with his wife and another protestor, to enter city hall without a mask.

His wife and the protestor were not challenged by police.

During the meeting, city health officer Debbie Swanson told the mayor and city councilors more mitigation with penalties attached are needed to slow what she called a crisis. Nearly 700 new cases have been reported since Friday alone.

Statement by Head of the Ahmadiyya Muslim Community in light of Recent Developments in France

0

Following today’s attack in Nice and following on from the murder of Samuel Paty on 16 October, the World Head of the Ahmadiyya Muslim Community, His Holiness, Hazrat Mirza Masroor Ahmad has condemned all forms of terrorism and extremism and called for mutual understanding and dialogue between all peoples and nations.

His Holiness, Hazrat Mirza Masroor Ahmad states:

“The murder and beheading of Samuel Paty and the attack in Nice earlier today must be condemned in the strongest possible terms. Such grievous attacks are completely against the teachings of Islam. Our religion does not permit terrorism or extremism under any circumstances and anyone who claims otherwise acts against the teachings of the Holy Quran and contrary to the noble character of the Holy Prophet of Islam (peace and blessings of Allah be upon him).

As the worldwide Head of the Ahmadiyya Muslim Community, I extend our deepest sympathies to the loved ones of the victims and to the French nation. Let it be clear that our condemnation and hatred of such attacks is not something new but has always been our position and stance. The Founder of the Ahmadiyya Muslim Community (peace be upon him) and his Successors have always categorically rejected all forms of violence or bloodshed in the name of religion.

The fallout from this heinous act has further exacerbated the tensions between the Islamic world and the West and between Muslims living in France and the rest of society. We consider this to be a source of deep regret and a means of further undermining the peace and stability of the world. We must all join together to root out all forms of extremism and to encourage mutual understanding and tolerance. From our perspective, the Ahmadiyya Muslim Community will spare no effort in our mission to foster a better understanding of the true and peaceful teachings of Islam in the world.”

(Photo: Sean Hawkey / WCC)On the eve of UN climate talks called COP21 in Paris, demonstrators gathered in the Place de la Republique in Paris. Frustrated at the planned climate march being banned following terror attacks the preceding weekend, riot police were brought in to ensure the march didn’t happen and some confrontations ensued on Nov. 29, 2015

In a week of brutal inter-ethnic violence and a series of attacks by extremists claiming to act in the name of Islam, the World Council of Churches has condemned the violence and called for confronting the brutal ideologies behind them.


“The unbearable toll of lives lost, and the impact on the affected communities and nations, must engage the concern, solidarity and action of the international community and all people of goodwill,” wrote Rev. Ioan Sauca, interim general secretary of the World Council of Churches.

This must be done to “stem the bloodshed and to confront the brutal ideologies behind such atrocities,” he said on Nov. 3.

He was commenting on violent extremist attacks in western Ethiopia, Kabul and Vienna that followed another attack in Nice France last week,

“In an attack on ethnic Amharas in western Ethiopia on November 1, 54 people are reported to have been killed, in a tragic escalation of the ethnic violence which threatens the very fabric of the Ethiopian nation.

The on Nov. 2, gunmen attacked Afghanistan’s largest university, killing at least 19 people and wounding more than a dozen, in the second deadly assault on an educational institution in the capital resulting in mass casualties in just over a week.

“And now in an apparent religiously-inspired extremist attack in Vienna – which began outside the Seitenstettengasse Synagogue, four people are reported killed and another 17 wounded,” said the WCC.

The WCC said the “Seitenstettengasse Synagogue, the main house of prayer for the Viennese Jewish community” has been the target of past violent attacks.

Gunmen opened fire in six different locations in the Vienna city center and at least one suspect was still at large.

The WCC categorically denounced all the attacks, “and its rejection of any attempts to justify such violence on religious grounds,” Sauca said.

“Merciful God, bring peace to a world increasingly riven by divisions and hatreds. Introduce compassion and wisdom to those leaders who so fearfully lack these qualities and who incite hatred and violence,” he prayed.

“Bring peace to a world increasingly riven by divisions and hatreds. Introduce compassion and wisdom to those leaders who so fearfully lack these qualities and who incite hatred and violence. Comfort all those who mourn the precious lives lost, and encourage and protect the communities now living in fear.”

On Oct 29, Pope Francis expressed his sorrow and offered prayers for a “savage attack” in at a church in the French city of Nice in which three people were killed in a knife attack described as a “terrorist incident” and which was denounced by the French president and the WCC.

And two days earlier WCC’s joined global Christians and the United Nations in expressing horror at the brutal attack on schoolchildren in Cameron in which assailants slaughtered at least eight students with firearms and machetes.

Holy See urges comprehensive approach to tackling inequality – Vatican News

Holy See urges comprehensive approach to tackling inequality - Vatican News

By Vatican News staff writer

Addressing participants at the 2020 Organization for Security and Cooperation in Europe (OSCE) Mediterranean Conference on Tuesday, Monsignor Janusz Urbańczyk stressed the importance of an integral approach in tackling the challenges of security and development amid the ongoing Covid-19 crisis.

The Permanent Representative of the Holy See to the OSCE said that security issues should always be addressed in a comprehensive manner, taking into consideration items such as “security, climate change, migration and the current economic and financial crisis exacerbated by the Covid-19 pandemic.”

Often, Msgr. Urbańczyk continued, “the level of economic growth of a country is the only factor considered in development.” However, he said, “the development we speak of cannot be restricted merely to economic growth.” For it to be authentic, “it must be well rounded; it must foster the development of each person and of the whole person.” 

The OSCE Conference was themed: “Promoting Security in the OSCE Mediterranean Region through Sustainable Development and Economic Growth.”

Integral development 

Echoing Pope Francis’ observation in the 2020 Encyclical letter Fratelli tutti, Msgr. Urbańczyk highlighted some economic rules that have proved effective for growth but not for integral human development. He notes that “wealth has increased, but together with inequality; with the result that ‘new forms of poverty are emerging’.”

Especially in these times marked by the wide-ranging effects of the ongoing Covid-19 pandemic, these new forms of poverty have not only exacerbated already existing poverties but have added new ones. Some of these include the limits of our health care systems, which are overwhelmed by the crisis; or the long-lasting consequences of the economic crisis; the lack of access to correct information and education; and the suffering caused by social isolation, increased violence, and distress.

“We cannot allow economics to be separated from human realities, nor development from the civilization in which it takes place,” said Msgr Urbańczyk. “What counts for us is the person – each individual, each community, and humanity as a whole.”

Women particularly affected

The pandemic has a disproportionate effect on women, Msgr. Urbańczyk noted. Many are impacted by a heavier workload, including telework, care, and domestic work; or by unpaid leaves and job losses, especially in the informal sector.

Highlighting the crucial role women play in the economy and society, the Monsignor stressed that “women must be recognized as dignified protagonists of their integral development,” adding that governments have the responsibility of protecting their dignity and providing them with a system of social safeguards and adequate compensation.

Inclusion of all

In light of the strong societal inequalities highlighted by the pandemic, Msgr. Urbańczyk recommended that the policies and tools put in place to respond to those in need be guided by two principles: the inclusion of all, and the protection of the sacredness of human life.

Although the pandemic is a test for individuals and society as a whole, Msgr. Urbańczyk concluded, “it also provides a real opportunity to seek new and innovative consensus-based solutions that are not divisive, politicized or partial, but that truly seek the common good and the integral human development of all.”

Ivory Coast president declared winner in contested election - Vatican News

Vatican News staff writer

The Ivory Coast electoral commission announced Tuesday morning that Alassane Ouattara has won re-election to a third term as president of the west African nation.

Opposition groups immediately rejected the results, citing Ivory Coast’s constitution which sets a two-term limit on the presidency. The incumbent argued, however, that the approval of a new constitution in 2016 allowed him to restart his mandate.

According to the results announced Tuesday, Ouattara won with over 94% of the vote, with a turnout of 53.90% of voters. Leaders of opposition groups, which had called for a boycott of the election, said turnout was closer to 10%. They said they did not recognize an Ouattara victory, and would instead form a transitional council that would work on organising “a fair, transparent, and inclusive presidential election.”

International election observers had already noted on Monday that “a significant portion of the population did not vote,” compared to previous elections. A statement released by the observer mission carried out by The Carter Center and Electoral Institute for Sustainable Democracy in Africa added, “these problems threaten public acceptance of the results and the country’s cohesion.”

Disputes over the election and Ouattara’s candidacy led to violence prior to Saturday’s election, with at least 30 people killed. Violence also broke out on election day itself, with reports of five deaths.

Recent elections in Ivory Coast have led to widespread unrest, with a brief civil war following the election in 2010 that left more than 3000 people dead.

The streets of the capital, Abidjan, remained calm in the early morning hours after the results were announced but it was unknown whether that would hold.

The opposition on Monday night said that its call for civil disobedience was still in effect and told its supporters “to remain mobilized until the final victory.” The U.N. refugee agency reported that as of Tuesday more than 3,200 Ivorians had fled to Liberia, Ghana and Togo fearing post-electoral violence.

Fish Scupper: EU and EU fail to bridge gaps on fisheries

The UK and European Union have so far failed to reach agreements on the three most contentious issues in their ongoing trade talks, both sides said.

The pair have not been able to reach agreements on fisheries, the so-called level playing field, and settling future disputes between Britain and the EU.

The impasse comes despite almost two weeks of intensive talks in a last-ditch attempt to strike a deal for when Britain’s transition agreement with the bloc comes to an end on 31 December.

Any deal to smooth billions of pounds of trade between the pair needs to be agreed by 15 November to give it time to be ratified by the EU before the transition period expires.

An update on the talks’ progress and the chances of a deal being struck is expected tomorrow or Thursday. Chief EU negotiator Michel Barnier said last week that “much remains to be done” before an agreement is reached.

A European Commission spokesperson said negotiators have not yet found a deal on sharing access to fishing waters after the post-Brexit transition period ends in December. 

“We have not yet found a solution on fisheries,” a Commission spokesperson said. They said “a lot more work remains to be done to get a deal”, adding: “we are not there yet”. 

A spokesman for Prime Minister Boris Johnson said: “We’ll only be able to make progress if the EU accepts the reality that the UK will have the right to control access to its waters at the end of this year.”

“There are significant gaps that do remain between our positions in the most difficult areas, and there is much work still to be done if we are to bridge those gaps.”

The Commission also said it would consider escalating its legal dispute with the UK over its violation of the Brexit withdrawal treaty.

The bloc sent London a formal letter of notice at the start of last month over the UK’s internal market bill – which Britain has admitted breached international law by breaching its earlier Brexit divorce settlement with the bloc.

The Commission spokesperson said that Britain had failed to reply and that the EU would therefore now consider the next step in the legal dispute – a reasoned opinion.

Indonesian Bishops call for dialogue in restive West Papua – Vatican News

Indonesian Bishops call for dialogue in restive West Papua - Vatican News

By Devin Watkins

Representatives of the Catholic Church in Indonesia, in particular from the West Papua province, have held talks with the country’s Coordinating Minister for Political, Legal, and Security Affairs.

The meeting was held on Sunday at Mr. Mahfud MD’s residence, and were aimed at discussing the various problems afflicting the restive province.

Present were Bishop Aloysius Murwito of Agats and Bishop Petrus Canisius Mandagi of Amboina, who is also the Apostolic Administrator of Merauke, along with Cardinal Ignatius Suharyo Hardjoatmodjo, President of Indonesia’s Conference of Catholic Bishops.

The encounter came after reports emerged that the Indonesian National Army had shot dead a Catholic catechist on 26 October. He was suspected of belonging to a separatist movement. 

The murder took place in Jalae Village, Sugapa District, in West Papua’s Intan Jaya Regency.

Harmful effects

Bishop Mandagi told UCA News that the hour-long meeting was meant to address “various problems in Papua, especially violence.” 

Indonesia’s Bishops, he added, are concerned about the situation, though he said no specific cases were discussed. 

Rather, talks focused on the suffering wrought by violence, both on local civilians as well as on security forces.

Dialogue, not violence

Bishop Mandagi said he told Mr. Mahfud that expanded dialogue with the people of Papua could help ease tensions. The local Catholic Church, he added, was always open to discussions.

“Papuans are good people,” he said. “Everyone including military, police, and church workers who come to Papua must not look down on them. We all need to settle Papua’s problems with dialogue, by respecting Papuans and without violence.”

The Bishop said military interventions only serve to exacerbate tensions.

Long-running unrest

A separatist movement has simmered in Indonesia’s West Papua and Papua provinces since the late 1960s, when the region became part of Indonesia.

Papuans complain of human rights abuses and discrimination from government authorities.

Following the meeting with Church leaders, Mr. Mahfud said the government would engage in further dialogue with Bishops in West Papua and Papua, as well as with other religious leaders.

Bishop Mandagi expressed his hopes for the cessation of violence.

“We want Papua to become a land of love, not a war zone,” he said.
